Hello. I didn't find a topic on this widespread group of tinder insects on the forum, so I ask permission to open a new one.

Representatives of the family are rarely found in collectibles, small in size and generally little known. They are rarely found openly, rarely found on the surface of trunks, do not come across when mowing, and fly weakly to the light. But there is a high probability of getting wood fungi from the nearest fruit body, which are more often dry, collapsing, mostly Polyporous, which is what your humble servant does during raids to study the coleoptera fauna-xylobionts and mycetobionts.

Below you will see photos of certain Ciidae specimens and the fruit bodies from which they were extracted using a photoextractor. Currently, the definition is based on the "green" determinant (compiled by L. V. Arnoldi, p. 329), so there may be inaccuracies in the synonymy that has been outdated since 1965. The author will be grateful for any corrections and comments. Active participation, collaboration, exchange of experience, articles, books, links, notes, and collectible materials are also welcome

okr. Kazan, June 1, 2011, basidioma Trametes cf. hirsuta from a dry branch of linden in aspen. the tree fell at least 5 years ago, and several dozen fruit bodies were found on the partially unrooted trunk, 6 of which were removed for research

obtained Ciidae and Lathridiidae material after photo-deflector run

specifically from these fruit bodies during the collection on June 1, 2011, it was possible to collect manually and extract the following cyid fauna with a photoextractor:

Cis bidentulus (1 copy)
Cis fissicornis (1 copy)
Cis micans (5 copies)
Cis striatulus (4 copies)
Ennearthron affinis (63 copies)
Ennearthron cornutum (1 specimen)
Rhopalodontus perforatus (5 specimens)

A month later, on June 2, 2011, the material was re-collected from the above-mentioned tree. of the remaining Trametes cf. hirsuta, the following species were added::

Cis boleti (1 copy)
Cis comptus (6 copies)
Rhopalodontus fronticornis (1 specimen)

roc. Kazan, May 20, 2011, Fomes fimentarius basidioma from dead birch in a pine-birch forest.

the larvae were found here, most likely representatives of the family. Ciidae, and also found in a variety of adults:

Cis jacquemartii (29 copies)
Cis nitidus (1 copy)
Ennearthron affine (8 copies)
Rhopalodontus perforatus (6 экз.)

The topic is quite interesting, at least for me. I myself have been working on this group of beetles for quite a long time. The names, of course, are outdated. The larva in the photo doesn't seem to be Ciidae. Cyids have clear short colored urogomphs of a different shape than in the drawing. Cis boleti, it seems to be determined correctly, as far as can be judged from these photos, as you understand, they are not perfect, and to determine ciid, a large magnification is often necessary. The males of C. fissicornis and C. comptus are precisely correctly identified. I'm not sure about Cis jacquemartii and C. castaneus (=nitidus). The differences between the species are much more noticeable when viewed from above: in C. jacquemartii, the lateral part of the prsp. it tapers anteriorly, while in C. castaneus the back is straight. I'm not sure about Cis submicans (=micans) either. Cis striatulus is apparently a female C. comptus, it is unlikely that C. striatulus is found in you, it is a more southern species and not so stocky. Sulcacis nitidus (=Ennearthron affine), Sulcacis fronticornis seem to be defined correctly, if the segments on the antennae are correctly counted. I'm not sure about Ennearthron cornutum, but I think I can see rows of dots. Well, in addition to Rhopalodontus perforatus, you may have R. strandi, look at the male's prothorax, head, and genitals.

Thank you. in this case, it is interesting to learn the literature with modern names and species. since the Far Eastern in Krivolutskaya is brought only to the genus with a reference as I understood to the work on the American fauna of Lawrence, they are not present in Polish, and in the German electronic determinant the word Ciidae is inactive. perhaps there are still references in the works of DKM, but they are not available to me at the moment

this larva is very small, maybe the first age even. A month later, I came to pick up bigger and more skelitised ones, including urogomphs. Cis submicans was first identified as C. hispidus (but that one has copper-colored scales, while this one has matte-shiny scales). with Cis comptus, yes, I got confused, but in the collections all beetles seem just the same not stocky, but elongated, except for a few specimens identified as C. comptus. So C. striatulus is even more slender? Ennearthron very well stand out on the antennae. Rhopalodontus strandi has not been found in the literature. in the collections, several different beetles were noticed. as for the southern ones, according to the latest data, we have populations of such southern species in the Republic of Tatarstan that do not fit into the local picture in any way. so it is better to check with a modern determinant, preferably koneshn and genital samples

speaking of maggots. In early June, I collected a small 5-cm cap of Pleurotus sp.
in a ravine on a dry aspen (forest-mixed birch). There were also a couple of Dacne bipustulata beetles. three weeks later, only one skin and several dozen live Dacne bipustulata remained in a sealed container from the oyster mushroom, which had already passed to the neighboring Trametes sp. I think it is quite an effective way to remove beetles in laboratory conditions.

I have experimented with similar samolovkami for tinder beetles on the appropriate bait. the boxes were fixed under large tinder boxes. The Ciidae themselves were not found. on the other hand, several staffs, skrytnoyedov Atomaria sp., a lot of flies, a baby Gnathoncus buyssoni, blackbirds, spangles and a large 2 mm were caught in this way. Aspidiphorus sp. (Aspidiphoridae). Trichonyx sulcicollis (Pselaphinae), which was not previously mentioned in the Volga region, is also frequently found on tinder plants, and Sphindus dubius (Sphindidae)is not uncommon
