03878061FF99D14EFE32FBE9852AFE11.taxon	description	Measurements – Body length: 555 – 585 (seven males), 630 (one female); notogaster width: 390 – 420 (seven males), 480 (one female). Integument (Figs. 4, 5, 20, 23, 24, 26) – Body brown. Surface densely microsculpturing tuberculate (visible under high magnification in dissected specimens); lamella and dorsal part of tutorium longitudinally striate; lateral side of body partially with microgranulate cerotegument. Prodorsum (Figs. 4 – 6, 8, 9, 17 – 24) – Rostrum with median rectangular ledge bordered by two deep incisions and with several (six to eight) lateral teeth (anterior tooth is largest). Lamella (excluding cusp) shorter than half of prodorsum; lamellar cusp slightly shorter than basal part of lamella, distally with strong inner tooth and small lateral outer tooth (sometimes reduced); cusps clearly separated medially, parallel or slightly divergent, connected mediobasally by one small interlamellar tooth. Rostral (52 – 56) and lamellar (71 – 75) setae rod-like, barbed; lamellar seta inserted in distal part of lamellar cusp; interlamellar seta (26 – 28) distinctly thinner than rostral and lamellar setae, setiform, slightly barbed; bothridial seta (34 – 41) with short exposed stalk and longer, fusiform (narrowed or pointed distally), slightly barbed head; in some specimens, bothridial head has apical spike; exobothridial seta not observable. Tutorium long, ridge-like, directed to rostrum, continue lateral and near the insertion of rostral seta. Notogaster (Figs. 4, 6, 7, 17 – 21, 25) – Eleven pairs of notogastral setae (28 – 34) setiform, smooth; each seta inserted on small tubercle. Opisthonotal gland opening and all lyrifissures well observable. Gnathosoma (Figs. 10 – 12) – Subcapitulum size: 154 – 169 × 86 – 90; subcapitular setae (a, h: 30 – 34; m: 37 – 41) setiform, slightly barbed; both adoral setae (26 – 30) setiform, barbed. Palp length: 90 – 97; setation: 0 - 2 - 1 - 3 - 9 (+ ω); postpalpal seta (7 – 9) spiniform, smooth. Chelicera length: 154 – 169; cheliceral setae (cha: 52 – 56; chb: 37 – 41) setiform, barbed. Epimeral and lateral podosomal regions (Figs. 5, 6, 19) – Epimeral setal formula: 3 - 1 - 3 - 3; setae 1 a, 2 a, 3 a (17 – 19) setiform, smooth, others (1 b, 3 b, 3 c: 30 – 34; 1 c, 4 a, 4 b, 4 c: 26 – 28) setiform, slightly barbed; 1 a, 2 a, 3 a, 3 c inserted on distinct tubercles, others on slight tubercles. Circumpedal carina distinct. Anogenital region (Figs 5 – 7, 19, 26) – Anogenital setal formula: 6 - 1 - 2 - 3; genital (17 – 19), anal (30 – 34) and adanal (30 – 34) setae setiform, erect, smooth; all adanal setae inserted on slight tubercles; both aggenital setae (30 – 34) setiform, erect, slightly barbed. Adanal lyrifissure transverse. Legs (Figs. 13 – 16, 19, 21, 27, 28) – Median claw thicker than lateral ones, all slightly barbed on dorsal side. Dorsoparaxial porose area on all femora and on trochanters III, IV distinct. Formulas of leg setation and solenidia: I (1 - 5 - 3 - 4 - 20) [1 - 2 - 2], II (1 - 4 - 2 - 4 - 16) [1 - 1 - 2], III (2 - 3 - 1 - 3 - 15) [1 - 1 - 0], IV (1 - 2 - 2 - 3 - 12) [0 - 1 - 0]; homology of setae and solenidia indicated in Table 1; seta s on tarsus I eupathidial, located between paired setae u and a; solenidia ω 1 and ω 2 on tarsi I, II and σ on genu III rod-like, rounded apically, other solenidia setiform to subflagellate. parentheses refer to a pair of setae. Diagnosis Based on our supplementary description and on the original description (Grishina 1984) of adult L. neonominatus, we propose the following diagnostic morphological traits for this species: Body length: 522 – 665. Surface microsculpturing tuberculate; lamella striate. Rostrum with median rectangular ledge, two incisions and several lateral teeth. Lamellar cusp distally with strong inner tooth and small outer tooth (sometimes reduced); cusps separate medially, connected mediobasally by small tooth. Rostral and lamellar setae medium-sized, rod-like, barbed; interlamellar seta short, setiform, slightly barbed; bothridial seta short, fusiform (sometimes with apical spike), slightly barbed, with head longer than stalk. All notogastral setae short, setiform, smooth, inserted on tubercles. All epimeral and anogenital setae short, setiform. Adanal lyrifissure transverse.	en	Ermilov, Sergey G., Kontschán, Jenő, Soromotin, Andrey V., Shulaev, Nikita A., Bayartogtokh, Badamdorj (2025): Supplementary description of Liacarus neonominatus Subías, 2004, with remarks on the genus Liacarus (Acari, Oribatida, Liacaridae).
