The Trogidae family includes about 300 species of world fauna [5]. In the fauna of Russia, there are 9 species of the genus Trox [1, 3]. I. V. Shokhin [3] gives 7 species of the family for the territory of Southern Russia. Data on the scavenger fauna of the Saratov region with direct collection points on its territory can be found in N. L. Sakharov's report on coleoptera of the Saratov province [2], where he cites 3 trox species. In this article, a list of Trogidae of the Saratov region is compiled on the basis of literature and collection data. Views listed for the region for the first time are marked with an asterisk (*).

I would like to express my gratitude to I. V. Kryukov, I. A. Zabaluev, A. B. Khalturin (Saratov), A.V. Kovalev (Ulyanovsk), A.M. Shapovalov (Orenburg), and Ya. N.Kovalenko (Belgorod).

Trogidae Macleay, 1819

Views shown for the region are marked with an asterisk (*) for the first time.

Trox cadaverinus Illiger, 1802
Sakharov, 1903: 40 - "flying in the daytime, often on sandy roads; 15.VI". - Saratov region, Tatishchevsky district, okr. s. Oktyabrsky gorodok (near Sakharov "Nikolaevsky gorodok").
Xerophilus, keratophage. VI-IX. The species is associated with sandy soils and is characteristic of both forest zones and steppes (Shokhin, 2007).
Material: Saratov region. Krasnoarmeysky district, surrounding village. Kamensky, 1989 (1 copy) leg. I. V. Kryukov, det. A. S. Sazhnev, coll. I. V. Kryukova.

*Trox eversmanni Krynicky, 1832
Botryobiont, common in rodent and fox burrows. According to Medvedev (1947), the coprophage, in our opinion, like other representatives of this genus, is a keratophagus. Xerophilus (Shokhin, 2007).
Material: Saratov region, Rtishchevsky district, Klyuchi village, Makarovsky zakaznik, na svet, 26-28. VI. 2008 (1 copy) leg. I. V. Kryukov, A. S. Sazhnev, det. A. S. Sazhnev, coll. A. S. Sazhneva.
Note: The Saratov specimen is black (approximately as in the second photo), and not rusty-red as it is written in most keys, the maximum legs are brown, the dimensions are 6.8 mm. Non-family specimens are known from Southern Russia and are tentatively identified as Trox perrisii Fairmaire, 1868; however, comparative data from Europe is required for full confidence (Shokhin, 2007). Taking into account the general distribution of the following species: Trox eversmanni - from the Czech Republic to Siberia, including Central Asia, sandy deserts and steppes; Trox perrisii-Europe, North Africa, Turkey, which is given for the first time in Southern Russia (Shokhin, 2007), and morphological features, we concluded that the find should be attributed to Trox eversmanni Krynicky, 1832.

Trox sabulosus ssp. sabulosus (Linnaeus, 1758)
Sakharov, 1903: 40 - " flying in the daytime; on the corpses of small animals: hedgehogs, mice, etc.".
The mesophile, or keratophagus, is confined to forest landscapes. The species is distributed from Europe to Primorye; the nominate subspecies occupies the west of its range, extending east to Lake Baikal (Shokhin, 2007).

Trox scaber (Linnaeus, 1767)
Sakharov, 1903: 40 - "let in the evenings and on the fire at night; 25. IV".
Mesophile, found in forest landscapes, where it is often associated with burrows and nests, keratophagus (Shokhin, 2007).
Material: "Saratov region" – without a more precise label, call SGAU.

*Trox hispidus ssp. niger Rossi, 1792
Xerophile, a keratophage that mainly adheres to open biotopes. The subspecies niger is distributed in Southern Europe, Southern Russia, Anatolia, and Central Asia up to China (Shokhin, 2007).
Material: Saratov region, Rtishchevsky district, Klyuchi village, Makarovsky zakaznik, na svet, 26-28. VI. 2008 (1 copy) leg. I. V. Kryukov, A. S. Sazhnev, det. A. S. Sazhnev, coll. A. S. Sazhneva.

Since we are talking about trogids from European Russia, I will add information on:

Trox morticinii Pallas, 1781

Biology. It is recorded in forest and forest-steppe areas, possibly associated with rodent burrows.
Distribution. Europe, North Africa, Turkey, and Southern Russia are listed for the first time."
