Identification of Hymenoptera (wasps, bees, ants)

Alexey, look, maybe there will be options for this bee, I still have a couple of types hung, I didn't know that it would be so difficult with them
Coelixys male, was caught in the south of the region, on raspberries. Dacha plot. 9-11 mm. I didn't find any similar ones based on the definitions of the Far East and Europe. The platypus is not covered with thick dirty white hairs. They are densely punctured, sometimes forming longitudinal wrinkles. Back in large, frequent points, quite shiny. The hair is light, erect, not thick. Bandages 2-4 solid, only 2 short interrupted, not wide, of the same width. The points of the abdomen are rough, the center of the tergites is weaker. 1st tergite in the hairs, light spots on the sides. There are no teeth on the 5th tergite. ON the 6th tergite, there are sharp teeth on the sides, two more teeth in the middle, and two more shortened and flattened tubercles-teeth above them. On the 6th stubble, there is a notch at the top. On the 4th tergite, the dots are slightly smaller than on the 3rd. On the top, the dots are smaller and very dense. At the top are shagreen ones. The spurs are black.
Perhaps C. mandibularis looks like this.…
[attachmentid()=120347]
[attachmentid()=120348]
[attachmentid()=120349]
[attachmentid()=120350]
The second male shows the same features as the first, but the pubescence of the platypus is much thicker with thick white hairs, which hide the sculpture of the platypus at the top.
[attachmentid()=120351]
[attachmentid()=120352]

This is definitely not Coelioxys mandibularis, as it would have very characteristic rectangular curved mandibles. Most likely it is Coelioxys inermis.

Echo of "Catch Reports"...

Is it possible to determine,
confirm or refute something from such photos ???

In the foreground Stizus fasciatus
in the background -???

13 [attachmentid()=118711]

Thank you in advance!

Can I tell you more about Eumenes tripunctatus? How many specimens have you seen, and what biotopes?

Once I laid out the female Ancistrocerus parietinus L , so it seems to me just her male, was caught approximately in the same place. South of the Krasnoyarsk Territory, Minusinsk.
About 8 mm. The whisker is yellow at the bottom, with yellow spots on the scutellum, tegulae, and posterior scutellum. The 2nd sternite is almost flat, not concave, on top with a yellow sling, on the 3rd sternite there is also a thin sling. There are 5 bandages on the tergites and a yellow spot on the 6th tergite.

No, this is not Ancistrocerus parietinus, it has a completely different clypeus. I can't say what it is yet, I recently caught some of them myself and haven't identified them yet.

Krasnoyarsk, slope of the Bazaikha river, glade, on the umbrella. Something is difficult to define, I think it is Symmorphus allobrogus (bifasciatus) female. On DV so, and on green, like bifasciatus is the main name.
10-11 mm. Srednespinka only in short hairs, much smaller than on the crown. The length of the inclined and horizontal parts of the 1st tertite is almost equal. The dots on top of it are quite large, but with blurry edges. At the apex, the median longitudinal groove is lost in a rather strong dotted line.
Median field of the gap. the segment is slightly glassy, obliquely striated, with a large pit under the posteriorly.
The prong on the rear basins is pointed.
Light bandages only on 1 and 2 tergites.
The shape of the parietal pits with slightly elongated depressions on one side that converge to each other.

Symmorphus with the view neither as unfortunately. South of the Krasnoyarsk Territory. Minusinsk city. 11-12 mm. On the mid-spine, the hairs are thick and long, like on the crown of the head. Shield with a longitudinal groove. The dotted line is less dense and deep than in murarius.
Yellow dots are found only on the sides of the prothorax. Sides of the gap. the segment is small and thick. striated, in murarius some wrinkles are raised. Its median field is rather rough and irregularly cellular-wrinkled. Sides of the mid-chest in sparse points, which turn into weak oblique wrinkles.
The teeth of the platbands are quite long.
The lower legs of the hind legs are brown in the middle, lighter at the ends. The hind legs are red.
On 1,2 tergites there are apical bandages, on the 4th there is an elongated light spot. 2-3 tergites at the top are faintly and imperceptibly dotted. The first tergite is shagreen, the dots are quite large, sparse, and not deep. As an option maybe angustatus

I found it quite an interesting specimen. With some errors and inaccuracies, I go out on the DV for Symmorphus mizuhonis Tsun female. Surroundings of Krasnoyarsk, on the umbrella streets. About 9 mm.
In addition to the short pubescence, there are long, slightly pressed hairs on the mid-spine. It is difficult to deal with the rollers at the base of the front sternite, but there does not seem to be a clear longitudinal roller that would rest against the arc-shaped roller at the top of the sternite. Transverse roller of the 1st tergite with a triangular protrusion in the middle. The dots are quite rare, but not small. Bandages are available only on 1 and 2 tergites. The gap.the segment from the sides of the central field b is coarsely cellular. Bottom with two elongated teeth. In the center with a longitudinal ridge, slightly shiny with oblique wrinkles. There is a deep fossa under the posteriorly. On the scutellum there is a powerful, wide groove in the center, its surface in very rare points. The parietal fossa is simple and rounded.

The aster bee is from the genus Amegilla.

I also thought that Amegilla, but my arolia has, and Amegilla doesn't seem to have them.

I also thought that Amegilla, but my arolia has them, and Amegilla doesn't seem to have them.

In this case, only one species is suitable - Anthophora bimaculata.

In this case, only one species is suitable - Anthophora bimaculata.

Is that what the green Heliophila bimaculata looks like?
I went to it, but I was confused: "summer uniforms; ... they nest in the ground colonially", and then it's the end of September, and all summer nothing like this has flown in this place.

The question is removed Anthophora bimaculata (Panzer, 1798) = Heliophila bimaculata Pz.
Blunted, watched "fauna", she sent me, and Google something immediately did not figure out.

Separately "autumn forms" as far as I remember (I haven't watched it for a long time) they're not there, so "summer" means they're not springtime. There can't be anything else on MO's list of bees.

Thank you so much for dispelling my doubts.

I was confused not by what happened in the fall, but in combination with coloniality. In theory, if the summer colonial, then in the summer a fairly large number should be, at least females should have been caught, and here two males at the end of September. And so there were quite a lot of female bumblebees and psytirchs flying around, but there hadn't been any males for several weeks, so I thought that it had recently hatched, something from late summer or autumn.

Could you provide a link to the list of bees MO.

I have to apologize, as I made two mistakes at once: I went to the forum from someone else's computer at work, where the ancient monitor "stretched" everything and tried to determine it from memory. Hence the incorrect definition.
First, by Ancistrocerus. I can now see (on a normal screen) that your male instance is quite consistent with A. parietinus! So everything is correct.
By Symmorphus. Again, you will have to take your words back, you had everything right about S. crassicornis (not S. murarius!).
Unfortunately, I can't tell from the last photos, because there is nothing to compare it with (only S. murarius, S. crassicornis, S. bifasciatus, S. debilitatus, S. gracilis are on hand). Basically, everything you've identified so far has been correct, so I don't have any more chances than you do for species that have nothing to compare them to. There are no special contradictions between the first and S. allobrogus and the second and S. angustatus. According to S. mizuhonis, everything is suitable, only the pubescence of the chest can not be called long and shaggy, and with the rollers on the first stubble, nothing is really clear.
Yes, S. allobrogus is the correct name. And under S. bifasciatus should be understood the species that is in the" green " - S. mutinensis.

Could you provide a link to the MO bee list?

Krasnoyarsk, slope of the Bazaikha river, glades, on the umbrella. Nothing but Ancistrocerus parietum goes to the female's head. About 11 mm
. The 2nd sternite is almost flat. The longitudinal grooves on it are almost the same length in the center and from the sides. Transverse roller on the first tergite with an obtuse recess in the middle. 1-5 tergites with yellow bandages. ON the 6th, rub the middle spot. There are two light spots on the scutellum and one spot on the posterior scutellum. The sides of the pronotum are not elongated into spines.

2 akulich-sibiria
Yes, this is A. parietum. Not quite the typical black pattern on the first tergum, it should be semicircular, not rectangular. But I think this can be attributed to variability, I also came across such things. The second sternite should be flat, and the fact that it is "concave" is hardly noticeable in comparison with other species in which it is really concave (A. gazella, for example). And although this sign on your photo can not be seen normally, I think there is no reason to doubt the definition, since the shoulder corners and the recess on the roller are the very thing.

thank you very much!! then I will leave only the genus names in the labels of the previous instances, especially with regard to angustatus.
I have a series of females Ancistrocerus trifasciatus, strange as it is, according to the signs I go to this species, but they are not very similar to each other.., I will try to photograph them later in series. And also on there are questions on Eumenes, Eudynerus
As it posted here this OS, once again I would like to check. Is it Pseudepipona herrichii??

Is it Pseudepipona herrichii??

Yes, it's a birthmark. Very variable in color appearance. You have such beautiful ones, but we have no red color at all. The size should be about 12 - 15 mm.
And at the expense of symmorphuses, - yes, leave "angustatus" as Symmorphus sp., and the rest are most likely defined correctly, so you can sign it.

I began to understand a little what it means to have a flat or raised base of the 2nd tergite. Therefore, I began to review some types. Previously posted Ancistrocerus trifasciatus, here's what I think about it. Still, it seems to me that the base of the 2nd tertite is raised. I have two options: either it is a male nigricornis or scoticus.
After the raised base, the surface is straight, if it is curved, it is almost invisible. The platypus is of equal length and width, its top with rather developed teeth, along the front and side edges with a thin transparent border. The sides of the pronotum are quite sharp, but not elongated into a sharp spike, but this may be a relative sign. On tergites only 1-3 yellow bandages, while on the 3rd it is not complete from the sides. On the first tergite, the band is not so thick. The temples at the base of the mandibles are strongly narrowed. There are yellow spots near the inner edge of the eyes. There is a light spot on the forehead. The body hair is light. The hind legs are yellow with a black side. I'm leaning towards scoticus

Here are three females that I think belong to the same species - Ancistrocerus trifasciatus.
The second sternite is uniformly convex in all cases, without sharp rises. No. 1 has a more gentle, almost straight line, and No. 2,3 has a more rounded one. No. 1,3 has a full-face rounded face, yellow spots at the inner edges of the eyes, No. 2 has a wider face, there are no spots near the eyes.
No. 1 lower legs are black on the outside, the first segment of the legs is partly black, the rest of the legs and legs are brown-red.
No. 2 is more black, the color of the paws is also brown-red.
No. 3 lower legs are black with yellow stripes, legs are almost black, the last segment of the legs is yellow.
The main segment of the antennae in No. 1,3 has a yellow stripe on the inside along the segment, the stripe is slightly expanded at the top, and in No. 2 it is completely black.
Alexander, can you say this is the variability of one species or different species? It seems to me that No. 1,3 is trifasciatus and No. 2 is ichneumonideus.
№1



№2




№3

I'm leaning towards scoticus

I agree, - A. scoticus. I don't have this type in my collection either, but all the signs of it are there.
In addition to differences in the shape of the second sternite, males of A. nigricornis should have a more elongated platelet with a narrower notch and spiny shoulder angles.

Alexander, what are the main differences between males of zfrietum and parietinus?..I already posted the latter here, but again doubts between these two types. I have another copy, which, unlike the previously posted one, does not have yellow spots on the shield and back of the shield...Longitudinal furrows on the 2nd sternum are quite difficult to understand, they are too long than from the sides or not. And another difference is only 4 yellow stripes on tergites....

here is the second one, you can compare it with the photos previously posted on this page

It seems to me that No. 1,3 is trifasciatus and No. 2 is ichneumonideus.

Me too. Again, I don't have the second one on hand.
But a good sign is the shape of the first tergite. In trifasciatus, it is noticeably longer. The shape of the head and the presence of yellow spots near the eyes-too.
In terms of coloration, yes, the variability can be quite strong.
But the degree of curvature of the second sternite is not clear to me. Taken from different angles, not strictly in profile, sometimes not visible. But personally, I caught for example A. parietum with both flat and slightly concave.

here is the second one, you can compare it with the photos previously posted on this page

This is not parietinus.
It is very similar to parietum.
Now I doubt again that the last one was A. parietinus.
Most likely parietum, but the signs are poorly visible.
I've never identified an OS from photos before, but the collection has never had any problems distinguishing between these types. As for males, A. parietum has a second sternum that is flat or concave at the base, the shoulder angles are almost rectangular, the platypus is longer (slightly longer than the width) and with a narrow notch (about 1/5 of the width). In A. parietinus, the second sternite is always clearly uniformly convex, the shoulder angles are in the form of spines, the platypus is clearly shorter than its width and with a wide notch (approximately 1/3 of the width). In addition, the latter type is larger. As for the color , it is very variable. However, the light pattern on the posterior scutellum (and in males, on the scutellum) is not characteristic of parietinus, in contrast to parietum.

Alexander tell me what is the main name now?7 bifasciatus, sinuatus or mutinensis, it seems to have found a handsome male of this species, just according to different determinants, the name is different...Tell me, do you have any separate qualifiers for childbirth? I think such literature would help me a lot: -)

The correct one is bifasciatus.
For what specific births? Or did you mean the gender determinant?

for a snack, another view that never reached the view today, tomorrow I will try to post a photo and sort out the problem couple of males, thank
you We have an hour in the morning already, tomorrow for the "favorite" work....

well, ancistrocerus, simmorphus, odynerus, eumenes from the latter genus I have a couple of instances, while they are listed as mongolicus, but everything is not clear at all. I don't have many caught instances from these oss.

By Symmorphus - http://www.aseanbiodiversity.info/Abstract/51008768.pdf
Also for this and other specified genera, there is the fauna of Europe in German, Gusenleitner. Can I search for links if necessary?

Yes, I forgot. According to Odynerus, the best determinant of Kurzenko (1977) in the volume of the USSR. Do you have any?

thanks for the link on simmorphuses, as for Kurzenko, no, I don't have it. On vespids I have only standard and I think already outdated-the European part and DV.

Here's Gusenleitner. Bad drawings everywhere and in German. But still.

The latter has an incorrect drawing of A. trifasciatus (second sternite on the side).

aha, I understood what kind of drawing, thank you so much for the info, sorry not English. while useful drawings.

What wasp?

IMG_4018________.jpg — (130.05к)

this is horntail

symmorphus sp was caught in the city of Krasnoyarsk, on the sandy bank of the river. 8-9 mm. I couldn't decide on the exact type.
Three light stripes on the abdomen. On the 1,2 and 4 th tergites. Characteristic shape of the top of the platband, the teeth are not large, extending to the sides, located at a fairly large distance from each other, between them with a very weak notch, almost straight top. The vertical part of the 1st tergite is almost equal to the horizontal part, the points on it are quite deep, rough, and the median longitudinal line is poorly marked. The sides of the tergite are slightly descending to the base. There are only small standing hairs on the back. Rough punctuation does not reach the base of the mid-spine. Median field of the gap.the body is quite shiny, without any visible striation. Valvula gap.segment as I understand it is pointed. The parietal fossae are simple, rather far apart, and their diameter is smaller than the lateral ocelli. At the very base of the crown there is a small longitudinal short roller. The sides of the chest are quite shiny, with sparse, rather rough spots. The corners of the pronotum are not elongated into spines.
It would be great to go out on bifasciatus, but the main distinguishing feature, like the ratio of the horizontal and vertical parts of the 1st tergite, does not go.
as a variant of allobrogus, but the structure of the gap.the segment doesn't match my previously defined ones, and my valvules are rounded. There is also a pointed bump on the rear basins.

Desalination of the city of Krasnoyarsk. On umbrella sites. About 7-8 mm. The hairs on the back are only small. The vertical part of the 1st tergite is smaller than the horizontal one. The punctuation on it is rough, strongly conceals the longitudinal groove. Two yellow bandages on 1-2 tergites, and on the 4th there is a shortened strip. Sides of the median field of the gap.the segments are bounded by improperly raised folds. The sides are clearly creased and dimpled. The sides of the chest in rare uniform clear points. I'm leaning towards Symmorphus bifasciatus L male

The female is Symmorphus connexus.
Male - I also get S. bifasciatus, although I don't have a copy of S. fuscipes at hand for comparison. There are no serious differences from my S. bifasciatus.

Symmorphus male is about 8-9 mm. Achinsky district of the Krasnoyarsk Territory.
As I understand it, the main ratio of the vertical and horizontal parts of the first tergite is here. The horizontal part is larger than the vertical one. And so in many ways similar to angustatus.
A large yellow spot on the architrave, the teeth on its top are quite sharp, pointing forward. There are no yellow spots near the eyes. The last four members of the mustache have yellowish thyloids. The upper part of the mustache is completely black. The hairs on the back are quite thick, raised, slightly smaller than on the head, but not as small as in bifasciatus. Large dots on the back reach to the base. The points on the sides of the chest and back of the chest are large and deep. Valvula gap. a segment with a drawn tip. The median field is honeycombed at the top, with a slightly glassy center. The dots on the horizontal part of the first tergite are large and frequent. The longitudinal furrow is faintly visible due to the dotted line. The transverse roller between the planes is clear, raised. The sides of the pronotum are quite well defined, clear. Well only bifasciatus…
