V. 21; (NHMC) .</p><p>Diagnosis.</p><p>Trochoideus tonkineus appears to be similar to T. sinensis sp. nov. in having a glabrous, dark brown and elongate-oval body. However, T. tonkineus differs from T. sinensis sp. nov. by the antennomere 4 in males (Fig. 19) elongate-oval in shape (vs. broadly oval); in females (Fig. 20) sides almost parallel, tridentate apically (vs. elongated triangle, deeply and widely emarginate apically); pronotum and elytra with fine punctures (vs. coarse punctures); and pronotum with anterior margin concave medially (vs. weakly arcuate medially).</p><p>Description of female.</p><p>Body (Figs 18 B, 20) length 4.8 mm; body long and oval, 2.0 times as long as wide; weakly convex; smooth, rather shiny. Dorsal surfaces mostly dark brown with antennae, clypeus, labrum, mandibles and legs light brown; ventral surfaces dark brown but slightly lighter than dorsal surfaces, elytral epipleura same colour as dorsal surfaces.</p><p>Head. Antenna (Fig. 19) 4 - segmented, scape subglobose, 1.5 times longer than wide; pedicel longer than wide, concave medially; antennomere 3 nearly triangular, widened apically, 1.8 times wider than pedicel; antennomere 4 nearly parallel-sided, about 2.4 times as long as wide, dorsal and ventral surfaces with deep, wide concavity medially, tridentate apically. Maxilla with terminal palpomere 1.5 times as long as wide, sides strongly tapering towards apex, arcuate apically.</p><p>Thorax. Pronotum 1.2 mm long, 1.6 mm wide; about 0.8 times as long as wide; anterior margin distinctly concave medially; sides curved, widest near 1 / 2 of pronotal length; anterior and lateral edges very narrowly bordered; disc rather convex, median furrow absent; pronotal surface polished between punctures, punctation rather dense and fine; lateral sulci distinct, linear, extending nearly to 1 / 4 of pronotal length, with trianglar concave area medio-basally; basal sulcus poorly developed. Prosternal process distinctly narrower than intercoxal process of mesoventrite, not extending beyond front coxae; sides nearly straight, weakly truncate apically. Mesoventrite with intercoxal process extending to approximate 1 / 2 length of mesocoxae, nearly parallel-sided, weakly rounded apically. Elytra 3.0 mm long, 2.4 mm wide; 1.3 times as long as wide; 2.5 times longer than pronotum, 1.5 times wider than pronotum; elytral surface polished between punctures, punctations dense, coarser than those on pronotum; sides curved, widest near anterior 1 / 4 of elytral length; then converging apically; humeri weakly prominent; elytral apices rounded. Legs with fore and mid tibiae simple, gradually widened apically, metatibia with inner edge extending in a triangular tooth at apex.</p><p>Abdomen with six freely articulated ventrites. Ventrite 1 nearly as long as three subsequent ventrites combined; ventrites 2–4 subequal in length; ventrite 5 longer than previous 3 ventrites; ventrite 6 nearly semi-circular in shape, rounded apically.</p><p>Measurements (in mm).

Type species: Pseudopaussus monstrosus Schulze, 1916 .</p><p>Description (modified from Tomaszewska 2000).</p><p>Body 3.0- 4.2 mm long, weakly elongate, moderately convex, shiny. Dorsal surfaces with dense and rather short pubescence; densely and confusedly punctate. Colour light to dark brown, sometimes with contrasting markings on the elytra. Antenna with 4 antennomeres (but there are species of Trochoideus with females that have 7 antennomeres), almost as long as head and thorax together; terminal antennomeres greatly enlarged, especially in male. Mandible with large tooth and two smaller subapical teeth. Maxilla with palpomere 1 smallest; palpomere 2 twice as long as 1 or 3; terminal palpomere longer than 2 and 3 combined, cylindrical, tapering, narrowly rounded apically. Labium with palpi widely separated at base, terminal palpomere large, subquadrate. Pronotum widest near midlength; lateral edges densely and finely denticulate and setose; basal sulcus hardly visible; lateral sulci in form of shallow, triangular depressions; anterior angles rounded; posterior angles slightly produced, acute. Prosternal process very narrow, extends to posterior margin of coxae, rounded apically. Mesoventral process narrow and elongate, not extending beyond posterior margin of mesocoxae. Elytral epipleuron narrow, incomplete apically. Leg with tibia scarcely widening towards tarsus, surrounded by short, spines apically. Tarsal formula 4-4 - 4 in both sexes; tarsomeres 1 and 2 weakly lobed ventrally; tarsomeres 3 slightly shorter than tarsomeres 2. Abdomen with six freely articulated ventrites; ventrites 2 and 3 subequal in length. Aedeagus comparatively short, weakly sclerotized, scarcely curved. Tegmen with large tegminal plate; tegminal strut submembranous, slender, slightly shorter than tegminal plate.</p><p>Diagnosis.</p><p>Trochoideus resembles two other genera of Pleganophorinae in appearance. However, the pronotum without a median sulcus can separate it from Dadocerus, which has the pronotum with a median longitudinal sulcus; and the pronotum with posterior angles not spinose can separate it from Pleganophorus, which has the pronotum with the posterior angles developed into long, sharp spines (Strohecker 1953).</p></div>	https://treatment.plazi.org/id/A80CADAF58AA52AB9058A02F9DFA01AC	Public Domain	No known copyright restrictions apply.
