description: Brevicopius gen. nov.
Type species. Fortunia jianfenglingensis Chen, Zhang et Chang, 2014
Description. Head with eyes slightly narrower than pronotum (Fig. 1). Vertex transverse, 1.6 times as wide as long medially, anterior margin almost straight, posterior margin emarginate, lateral margins distinctly elevated, with median carina (Figs. 1, 6). Frons longer than wide, slightly widening above the clypeus, lateral margin subparallel; upper magin angulately incised, lateral margins strongly elevated and slightly sinute near to distal third; frons with three carinae, median carina present at upper and median area of frons, very strong at middle, sublateral carinae arcuate, united far away from upper margin of the frons, ending at frontal nasale and not reaching the clypeus, disc densely wrinkly between sublateral carinae, with a row of big tubercules along the outside of sublateral carinae, otherwise, with small tubercules at upper and lateral area; disc moderately depressed at upper part, smally roundly swollen below apex of median carina, and protruded forward as short nasale near to clypeus in lateral view (Figs 2–4, 7). Rostrum reaching hind trochanters (Fig. 3). Eyes elliptical and well developed, with small excision just above antennae in lateral view (Figs 2–4). Antennae with scape short, ring-shaped, pedicel subglobose with numerous sensory organs (Figs 2–4).
Pronotum large, covered with small tubercules, anterior margin convex between eyes medially, posterior margin arcuately convex at middle, with median carina and with two small rounded calli on both sides of median catina near its posterior margin; lateral lobes considerably enlarged and flabellate in frontal view, with small granules on the whole surface and tubercules on upper half along the inside of laterocaudal margin, apical margin slightly concave, apicolateral angles nearly right (Fig. 1). Mesonotum wide and relatively short, slightly narrower than pronotum; anterior and lateral margins distinctly elevated, disc flat, with three carinae, median carina anteriorly thin and distinctly thick posteriorly, sublateral carinae relatively thin and short, with several small tubercules on lateral area outside the sublateral carinae (Fig. 1).
Tegmina nealy oblongus, with narrow hypocostal plate, weakly narrow to rounded apex, costal and claval margins subparallel, costal margin shallowly concave at basal third. Claval margin relatively straight, caudal angle bent down roundly; Sc+R forking near to basel cell, each branch simple, MP vein forking in its basal third, CuA vein independently emiting from the underneath of basal cell, forking at basal half, CuA1 forked distally, CuA2 forked just before the terminal tip of clavus; CuP distinct, clavus short, and reaching the middle of tegmina, Pcu + A1 running to CuP, but very close to the apex of clavus, Pcu and A1 united at distal third of clavus, with reticulated transverse veinlets between the Pcu and CuP, 12–14 transverse veinlets between A1 vein and A2; longitudinal veins distinctly prominent and transverse veins relatively weak, transverse veinlets comparatively dense and reticulated at apical half (Fig. 1). Hind wings well-developed, trilobed, wider than tegmina, with deep cleft at apex of CuP vein, anal lobe rudimentary; longitudinal veins R, M, CuA, Pcu, A1 and A2 forking except CuP, among which, R forking at middle of the wing, M forking at distal half, CuA forking nearly before M, Pcu forking before wing middle, A1 and A2 forking distally; R, M, CuA, A1 and A2 veins distinct, CuP and Pcu relatively gracile; with one transverse vein at middle between C and R veins, about 4–5 transverse veins between R and M, 7–9 transverse veins between M and CuA, and 8–10 transverse veins between CuA and CuP from base to middle of wing; transverse veinlets obviously dense and reticulated after the middle of wing (Fig. 5). Anterior tibiae distinctly compressed and dilated, posterior tibiae with two lateral spines distally. Spinal formula of hind leg 7–8– 2.
Male genitalia: Anal tube nearly ovaliform in dorsal view (Fig. 12). Aedeagus shallowly U-shaped, phallus with a pair of slender and short hooks ventrally (Figs. 10, 11). Genital styles in profile view nearly triangular, caudo-ventral angle strongly convex, hind margin strongly angularly concave medially, and with transverse carina below the capitulum (Fig. 8). Capitulum of style long, tip pointed in lateral view, lateral tooth wide and large (Fig. 9). Pygofer with posterior margin strongly convex medially in lateral view (Fig. 8).
Female genitalia: Anal tube nearly quadrilateral in dorsal view (Fig. 15). Gonoplacs wide and short in lateral view, apical margin membranous and oblique, with one blunt projection at base in dorsal view, third gonoplac lobes with fork wide, faintly sclerotized and pigmented (Figs 13, 14). Gonapophyses IX moderately large, elliptical in dorsal view, proximal part of posterior connective lamina convex, median field very large with two lobes, and extremely elevated wholly (Figs 16, 17). Gonospiculum bridge small, basal part relatively large, nearly quadrilateral and flat, apical part very short (Figs 16, 17). Anterior connective lamina of gonapophysis VIII with three strong teeth in apical group and four teeth in lateral group (Fig. 18). Gonocoxae VIII nearly rectangular, with hind margin concave (Fig. 18).
Etymology. The generic name is derived from combination of Latin root prefix “brevi-” and “-copius”, referring to the frons distinctly short. The name is masculine in gender.
Diagnosis. This genus is similar to genus Mincopius Distant, 1909, but differs from the latter in the following characters: 1) frons short, slightly widening to clypeus, about 1.2 times longer than wider at widest in middle line, with median carina disappear near united lateral carina, in Mincopius, frons relatively long, about twice as long as wide in middle line, with median carina elongate, almost reaching to clypeus; 2) tegmina with narrow hypocostal plate, CuA vein forked appreciably at basal half of tegmina, bifurcate after M fork, CuP vein well marked throughout its length, in the Mincopius, without hypocostal plate, CuA vein forked extremely closed to basal cell, bifurcate in front of M fork, CuP vein well marked only proximally.
The new genus also resembles Fortunia Distant, 1909, but can be separated from the latter by the following characters: 1) frons relatively short and broad, elarged to apex of nasale, apical margin slightly convex medially (in dorsal view), lateral margins of the frons not joining at apex of nasale (in ventral view), upper margin deeply concave (in frontal view), disc with a small round swelling below apex of median carina, in Fortunia, frons relatively long and narrow, basal part almost as wide as apical part, apical margin emarginate medially (in dorsal view), lateral margins of the frons curved inwards, almost joining at apex of nasale (in ventral view), upper margin straight (in frontal view), disc flat, without swelling (Ôuchi, 1940, Fig. 1: a–b; Chan & Yang, 1994, Fig. 35: A–C; Gnezdilov & Wilson, 2007, Figs. 10–11; Chen et al., 2014, Fig. 2 –45: A–E); 2) gonoplacs forking at basal half (Fig. 13), in Fortunia, gonoplacs forking at distal one third (Fig. 20); 3) anterior connective lamina of gonapophysis VIII with teeth in lateral group appearing from apical margin to dorsal margin, apicodorsal angle angulate (Fig. 18), in Fortunia, anterior connective lamina of gonapophysis VIII with teeth in lateral group appearing at apical margin, and apicodorsal angle widely rounded (Fig. 19).
Distribution. China (Hainan).
