Diagnosis. Neodima belousovi Prosvirov & Kundrata sp. nov. differs from N. sichuanensis in the smaller and shallower punctures on prothorax (Figs 2C, D; 3C; 6C, D; 7B, C, D), longer posterior pronotal angles (Figs 2D; 3C; 6D; 7B, C), straight frontal margin of mesanepisternum (Figs 2C, 3D, 6C, 7D), broader metaxocal plates (Figs 2F, 3E, 6F), more elongate elytra with smaller punctures (Figs 1A; 3A; 5A, D, G), aedeagal median lobe distinctly surpassing parameres and bearing the sclerotized hook-like sclerite inside (only slightly surpassing parameres and without visible sclerites inside in N. sichuanensis), and the paramere apex without a subapical hook (Figs. 2 I–K; 6L–N). Neodima cechovskyi has uniformly colored body without dark elytral stripes (Fig. 1D), elongate elytra, which are about 2.20 times as long as wide (1.85–1.95 times in N. belousovi Prosvirov & Kundrata sp. nov.; Figs 1D; 5A, D, G), and much larger elytral punctures.
Description. Holotype, male. Body length 5.50 mm; width 1.80 mm. Body (Fig. 5 A–C) elongate, moderately convex. Head dark brown, mandibles brown with darker apex, remaining mouthparts pale yellow, antennae brown, from antennomere III partially dark brown apically; pronotum dark brown, brown at anterior and posterior parts, scutellar shield brown, darker along margins, elytra yellowish brown, with darker humeri, each elytron with broad dark brown longitudinal stripe from stria I to stria VII, stripe developed almost in whole length of elytron; hypomeron and prosternum brown, prosternum darker in middle; meso- and metaventite as well as metacoxal plates pale yellow; abdomen dark brown, each ventite yellowish anteriorly and posteriorly; legs pale yellow; pubescence golden.
Head (Fig. 6A, D) including eyes about 0.7 times as wide as pronotum; frons apically with almost smooth edge but not forming frontal carina, rounded in lateral view, overhanging base of labrum; surface above antennal insertions elevated but not forming carinae. Head surface sparsely punctate; punctures rather small, intervals between punctures mostly equal 2–3 puncture diameter. Maxillary palpus with palpomere III about as long as wide. Antenna (Figs 5 A–C, 6B) slightly surpassing midlength of elytra, length ratio of antennomeres II–IV = 1.00: 1.10: 1.33, pedicel shortest, about twice as long as wide; antennomere III elongate, about 2.5 times as long as wide; antennomeres IV–X elongate, about 3–3.5 times as long as wide; ultimate antennomere elongate, about 1.2 times as long as penultimate antennomere, about four times as long as wide, gradually widened subapically, narrowed apically.
Pronotum (Figs 5A, 6D) 1.2 times as wide as long if measured along midline (length at midline 1.20 mm; width 1.40 mm), and about as wide as long if measured between anterior and posterior angles, strongly convex, mainly at middle.Anterior angles very slightly produced forward; sides before half more or less evenly narrowing anteriad and posteriad, anteriorly narrowing more sharply than posteriorly; posterior angles moderately long, only very slightly divergent. Disc moderately densely punctate; punctures medium-sized, rather deep, rounded; interstices smooth. Hypomeron densely punctate, punctures rather large, oval and deep. Prosternum (Figs 5B, 6C) including prosternal process about 1.5 times as long as wide, in front of coxal cavities 0.9 times as long as wide; with punctation sparser than on hypomeron, punctures smaller and rounded; prosternal process about 0.65 times as long as prosternum in front of procoxal cavities. Scutellar shield (Fig. 6E) suboval, about 1.4 times as wide as long; anterior margin slightly extended medially, with distinct edge; posterior margin rounded. Mesoventrite (Figs 5B, 6C) transverse, medial prostrusion of frontal margin apically only slightly emarginate medially; procoxal rests indistinct. Mesanepisternum with frontal margin slightly rounded, with indistinct lateral extensions of procoxal rests. Metacoxal plate (Fig. 6F) strongly reduced towards body edge, from about half forming only narrow strip. Elytra (Fig. 5A, C) elongate, together 1.95 times as long as wide, widest about at middle, from humeri more or less gradually widened to middle, then gradually narrowed towards apex, with striae formed by lines of large window-like punctures; interstriae reduced to convex ridges; laterally strongly bent downwards after interstria VI at basal half.
Abdomen (Fig. 5B) with ventrites rather sparsely puncate, punctures small, circular; apical ventrite truncate posteriorly. Tergite VIII (Fig. 6G) broadly triangular, about 1.6 times as wide as long, apically rounded, sparcely punctate, covered with sparse pubescence. Sternite VIII (Fig. 6H) transverse, about 1.6 times as wide as long, apicomedially emarginate. Tergite IX (Fig. 6I) subtriangular, about 1.2 times as wide as long, deeply emarginate apically; tergite X (Fig. 6I) rather small, widely rounded apically. Sternite IX (Fig. 6J) elongate, about 3.6 times as long as wide, apically widely rounded. Sternite X (Fig. 6K) membranous. Aedeagus (Figs 6 L–N) 3.5 times as long as wide. Median lobe elongate, notably surpassing parameres, gradually narrowed towards anterior half, then sharply constricted and gradually narrowing towards apex, apically narrowly rounded, bears sclerotized hook-like sclerite inside, with rather short basal struts. Paramere elongate, broadened at anterior third, gradually tapering at anterior quarter, apex rounded. Phallobase small, narrow, U-shaped, slightly widened anteriorly.
Female (Figs 5 D–I, 7). Body length 5.00 mm; width 1.70–1.75 mm. Similar to male in most characters. Body coloration slightly lighter.Antenna (Figs 5 D–I, 7A) shorter, reaching or only slightly surpassing midlength of elytra, length ratio of antennomeres II–IV = 1.00: 1.25: 1.45; antennomeres IV–X elongate, about 3.0–3.5 times as long as wide; posterior angles of pronotum slightly longer and more divergent than in male; prosternal sutures (Figs 5E, 7D) almost straight; anterior margin of scutellar shield (Fig. 7E, F) almost rounded medially. Tergite VIII (Fig. 7G, H, J, K) triangular or broadly triangular, about as long as wide to about 1.4 times as wide as long, apically narrowly or widely rounded, finely punctate, covered with sparse pubescence. Sternite VIII (Fig. 7G, H, J, K) more or less broadly triangular, about as long as wide to about 1.5 times as wide as long, apically widely rounded, spiculum ventrale about 4–6 times sternite length. Ovipositor (Fig. 7L) relatively long; with paraprocts about 4.0–4.5 times as long as gonocoxites; gonocoxite (Fig. 7I) narrowed to apex; stylus elongate. Bursa copulatrix (Fig. 7M) elongate, sac-like, without any sclerotized structures.
Immature stages unknown.
Distribution. China: Sichuan Province, Ya‘an City (Fig. 8).
Etymology. This species is named in honor of the distinguished Russian entomologist Dr. Igor A. Belousov, one of the collectors of the type series.
