731687CCFFC54C25FF37EF87FA37F805.taxon	diagnosis	Differential diagnosis. Based on the general shapes of the body and the aedeagus, the hind tarsomeres 1 – 4 together distinctly shorter than apical tarsomere and transverse preapical antennomeres, Sinaculia gen. n undoubtedly belongs to the tribe Omaliini. Regarding the general shape of small and convex body, with the presence of the distinctly crenulate lateral margins of the pronotum, Sinacrulia gen. n. can be compared with several genera which have recently been reviewed by Shavrin & Zanetti (2020): Palaearctic Acrulia Thomson, 1858 (three species), western palaearctic Dialycera Ganglbauer, 1895 (three species), Holarctic Acruliopsis Zerche, 2003 (five species), and Holarctic Hapalaraea Thomson, 1858 (six species). From all these genera Sinacrulia gen. n. can be distinguished by the following morphological features: 1) apical segment of the maxillary palpi very long and narrow, slightly less than three times as long as moderately broad penultimate segment, 2) the presence of indistinct pronotal impressions (S. sp.), 3) the shape of very broad median lobe, from widest middle strongly narrowed apically, 4) the shape of the very short parameres, reaching middle of the median lobe, 5) the presence of elongate accessory plates (“ accessory lamella ” according Zanetti (1987 )) rounded apically at level of middle part of the median lobe, 6) the missing of sclerotized spines of internal sac, 7) the presence of very long and strong flagellum. Based on the general shape of the transverse head evenly convex in middle, without shield-like median elevation and with moderately long temples, the shape of the slightly elongate antennomere 5, and the strong punctation of the forebody, Sinacrulia gen. n. is somewhat similar to the genus Acruliopsis (Zerche 2003, Shavrin 2013, Shavrin & Zanetti 2020), from which it differs by the missing of pubescence of the forebody, finer crenulation of lateral margins of the pronotum, longer elytra and different morphology of the aedeagus. From all genera of Omaliini it can be distinguished by the unusual shape of the aedeagus, and the presence of very long flagellum. Natural history. The species of Sinacrulia were collected at high elevations from 2970 to 3050 m a. s. l. by sifting of litter and mosses.	en	Shavrin, Alexey V.

731687CCFFC54C25FF37EF87FA37F805.taxon	etymology	Etymology. The name of the new genus is derived from the prefix Sino -, referring to China, and the genus name Acrulia, one of the relative taxa of the tribe Omaliini.	en	Shavrin, Alexey V. (2023): A new genus of Omaliini from China (Coleoptera: Staphylinidae: Omaliinae).

731687CCFFC54C25FF37EF87FA37F805.taxon	discussion	Remarks. The general structure of the aedeagus of Sinacrulia gen. n. is somewhat similar to that of some species of Omalium Gravenhorst, 1802 and Acrolocha Thomson 1858. Almost all species of these genera have developed accessory plates, sometimes strongly sclerotized and protruded apicad between elongate median lobe, and also have similar shapes of the parameres (usually more complicated in many species Omalium). The presence of large and long flagellum in Sinacrulia gen. n. is unique. Only species of some genera have short narrow flagellum not spirally folded in basal portion of the aedeagus (e. g. Carcinocephalus Berhauer, 1903, Omaliopsis Jeannel, 1940 (some species), Phloeonomus Heer, 1839, Tetradelus Fauvel, 1904). Usually, the very long flagellum with the spiral in basal portion of the aedeagus can be observed in some genera of the tribe Anthophagini Thomson, 1859: Hygrodromicus Tronquet, 1982 (Shavrin 2021 b, 2022), Trichodromeus Luze, 1903 (Zerche 1992, Shavrin 2012, 2021 a).	en	Shavrin, Alexey V.
