The new species can be distinguished from them by the shape of the postocular portion of the head with subacute angles distinctly protruded basad (as that in species of the acutangulum group), the shape of the pronotum broadest in apical third and with apical angles protruded anteriad (the pronotum of O. amplissimum is widest in apical third, but apical angles not protruded anteriad, and the pronotum of O. bilobum is widest slightly above middle and with anterior angles protruded anteriad), the shape of short apical part of the median lobe, different shape of the parameres and morphology of the internal sac.</p><p>Distribution. Omalium intermedium sp. nov. is known only from the type locality in Bagmati, central Nepal (Fig. 16).</p><p>Etymology. The specific epithet is the Latin adjective intermedius, - a, - um (intermediate). It refers to the intermediate shape of the pronotum if compared to related species.</p><p>Bionomics. Specimens were collected at elevations from 2550 to 2650 m a.s.l. Detailed bionomical data are unknown.</p></div>	https://treatment.plazi.org/id/03FF87A84204FF8C62B2F941705BFCAA	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

Omalium littorale is a widely distributed Western Palaearctic species, and also known from Middle Asia, Afghanistan and Pakistan (Shavrin 2023a). This species is morphologically variable both in external and internal features, especially in the length of the elytra and hind wings, proportions of the pronotum and the shape of the median lobe (Zanetti 2006; Shavrin &amp; Khachikov 2023; Shavrin 2023a). Aedeagus as in Fig. 3.</p><p>Homalium balassogloi was originally described based on “ 3 Exemplare ” from “See Issyk-Kul”. During the study of the collection of NMW, I found one female (Fig. 5) which undoubtedly belongs to the type serie. I designate this specimen as the lectotype. Measurements of the lectotype: HW: 0.45; HL: 0.32; OL: 0.11; TL: 0.07; AL: 0.87; PL: 0.37; PWmax: 0.60; PWmin: 0.52; ESL: 0.73; EW: 0.76; AW: 0.80; BL: 2.28. Based on the details of the morphology of the body, it similar to other studied specimens of O. littorale . Thus, I synonymized it with the latter species.</p><p>Omalium bucharicum was originally described based on a single specimen which was collected from “Repetek (Buchara)”. I studied the holotype from the collection of FMNH (see above). Based on the shape and details of the morphology of the body, it conspecific with O. littorale . Thus, it was synonymized with the latter species.</p></div>	https://treatment.plazi.org/id/03FF87A84203FF8F62B2FC0A7465FC76	Public Domain	No known copyright restrictions apply.

Neck with short and longitudinal wrinkles between punctures. Ocelli located at about level of postocular ridges; distance between ocelli and eyes about twice as long as distance between ocellus and posterior margin of eye. Antennomere 2 suboval, about twice as long as basal antennomere, 3 distinctly narrower than 2, 4 about twice shorter than 3, 5 distinctly longer and slightly broader than 4, 6 slightly broader than 5, 7 slightly broader than 6, 8 slightly longer and distinctly broader than 7, 9–10 distinctly longer and broader than 8.</p><p>Pronotum convex, slightly broader than long, 1.1 times as broad as head, widest slightly above middle.Anterior angles widely rounded. Anterior margin somewhat straight, slightly concave in middle. Posterior margin rounded, slightly concave in middle. Lateral portions widely impressed in middle and laterobasal parts. Surface of disc with two wide and deep longitudinal depressions, significantly broadened in mediobasal portion. Medioapical part with indistinct small and oval depression. Surface between wide pronotal depressions strongly elevated. Middle part with irregular longitudinal elevations between punctures, slightly stronger in medioapical area. Each lateroapical part with rounded moderately wide elevation.</p><p>Elytra about as long as broad, 1.6 times as long as pronotum, indistinctly broadened posteriad. Dorsal surface of each elytron with strong elevations between punctures.</p><p>Metatarsi 1.5 times as long as metatibia.</p><p>Abdomen as broad as elytra, with two small round wing-folding patches in middle of abdominal tergite IV.</p><p>Male. Posterior margin of abdominal tergite VIII straight. Posterior margin of abdominal sternite VIII widely sinuate. Aedeagus with moderately broad basal portion, gradually narrowed toward wide and elongate median lobe; median lobe from apical third gradually narrowed toward rounded apex; mediolateral portions with narrow elongate accessory plates curved apically; parameres short and narrow, reaching middle of median lobe, each with narrow apex, and one long and two short apical setae; internal sac wide and moderately long, with several long spines in apical and middle portions (Fig. 10). Lateral aspect of the aedeagus as in Fig. 11.</p><p>Female unknown.</p><p>Comparative notes. Based on the shape of the aedeagus, O. conoideum sp. nov. belongs to the Oxyacanthae group (Zanetti 1987; Shavrin 2023a). Based on the length of the body, and the general shape of the aedeagus with significantly shortened parameres and the presence of long spines in apical part of the internal sac, O. conoideum sp. nov. is similar to O. alticola Cameron, 1941, known from the Himalayan Region (Shavrin 2023a) and also from Sichuan (Shavrin 2025a), and to O. khmericum Shavrin, 2020, recently described from northern Laos (Shavrin 2020). Omalium conoideum sp. nov. can be distinguished from O. alticola by the slightly broader apical part of the pronotum, denser punctation and coarser elevations between punctures of the pronotum and the elytra, and significantly narrower median lobe. Based on the punctation of the forebody and the shape of narrower median lobe, O. conoideum sp. nov. is more similar to O. khmericum, but can be distinguished from it by the darker body, the shape of the pronotum widest slightly above middle (pronotum of O. khmericum is widest in or slightly before the middle), and the slightly narrower elytra. From both species it differs by the different structure of the internal sac and details of the external morphology of the aedeagus.</p><p>Distribution. Omalium conoideum sp. n ov. is known only from the type locality in Nantou Hsien, Taiwan.</p><p>Etymology. The specific epithet is the Latin adjective conoideus, - a, - um (similar). It alludes to the similarity of the shape of the aedeagus with that of O. alticola .</p><p>Bionomics. The specimen was collected at an elevation of 1600 m a.s.l. Detailed bionomical data are unknown.</p></div>	https://treatment.plazi.org/id/03FF87A84200FF8162B2FBFA705BFBC2	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

(cSh) .</p><p>Remarks. Omalium rivulare is one of the widely distributed species of the genus in the Holarctic Region (Herman 2001, Shavrin 2025b). It was recorded from Kazakhstan by Kashsheev (1984). Despite this, Kashsheev (1999) described O. kabakovi Kashcheev, 1999 from Dzhungar Alatau, Jetisu Region of Eastern Kazakhstan. The original description was based on seven specimens from the upper reaches of Tentek River. The author has not compared this species with other species of Omalium, but after the description he provided a key for “relative” species, including European O. laticolle Kraatz, 1857, Palaearctic O. curtipenne Mäklin, 1878 and widespread O. allardi Fairmaire &amp; Brisout de Barneville, 1859 . When I was last time in ZIN in 2016, I could not locate the types of O. kabakovi except for one male of O. rivulare from Altai Mts., East Kazakhstan (see above). Based on the morphological features provided in the original description and sketchy figure of the aedeagus (Fig. 2 in Kashsheev 1999), O. kabakovi is conspecific with the Holarctic O. rivulare . Thus, it was synonymized with the latter species.</p></div>	https://treatment.plazi.org/id/03FF87A8420AFF8562B2FB3F74C9F85F	Public Domain	No known copyright restrictions apply.
