description: <i>Hagrides</i> Jin, de Keyzer et &amp;Sacute;lipi&amp;nacute;ski, 2020 (Figs. 9, 14I, 15M, 17F) <i>Hagrides</i> Jin, de Keyzer et &amp;Sacute;lipi&amp;nacute;ski, 2020: 19. Type species <i>Cnemoplites princeps</i> Gahan, 1893, by original designation. <b> <i>Diagnostic combination (Male)</i>.</b> Large beetles, 30–70 mm long. Dorsum usually unicoloured, black or dark brown, sometimes with elytra reddish brown. Sexually dimorphic dense punctures absent. Head distinctly narrower than prothorax; frontoclypeal suture arcuate or broadly angulate; median groove complete. Antennal tubercles moderately prominent, rounded apically. Eyes large, weakly emarginate near antennal insertion, moderately separated dorsally. Mandibles about half of head capsule length, not sexually dimorphic, not bent towards ventral side, and unidentate apically. Antenna in male extending to or beyond the middle of elytra. Scape about 1/3–1/2 of head length, extending beyond posterior margin of eye, expanded apically, flat with blunt external edge; antennomere 3 slightly longer than scape and distinctly longer than antennomere 4. Mentum not fused to sub-mentum. Terminal palpomere of maxillary and labial palps elongate oval and apically slightly truncate. Prothorax transverse with lateral carina regularly spinose; anterior and posterior margins with complete beads. Pronotal disc usually glabrous, sometimes with very sparse and fine hairs, surface with dense coarse punctures. Prosternal process subparallel, extending far beyond procoxae, narrowly rounded or slightly pointed apically. Elytral surfaces strongly coriaceous, with at least two distinct costae, without adpressed hairs; inner apical angle with short spine. Abdominal ventrites 1–4 covered by lighter tomentose pile separated from glabrous posterior patch on each ventrite by rows of long erected setae. Legs relatively long and strong; femora with rows of sharp spines ventrally. Protibia with rows of spines, two or three sharp external projections apically and a pair of subequal spurs; tarsomere 3 moderately lobed; tarsomere 5 shorter than tarsomeres 1 and 2 combined. <i> <i>Description</i>.</i> <b>Male.</b> Length 30–70 mm. Dorsum usually uniformly brown or dark brown, sometimes with slightly reddish elytra. Head capsule approximately as long as wide, narrower than pronotum, and with very sharp genal projection. Mandibles about as long or slightly longer than half of head capsule, moderately curved inwards; each mandible wedge-shaped, very thick and strong on lateral side and near the base, unidentate at apex, with two extra teeth on incisor edge. Labrum transverse, anterior margin pointed medially with very dense setae; labrum separated from clypeus by a deep arcuate groove; dorsal surface of labrum and clypeus almost glabrous. Frontoclypeal suture angulate or broadly arcuate; median groove distinct and complete. Antennal tubercles relatively prominent, apex rounded. Antenna 11-segmented, filiform, extending to or beyond the middle of elytra; scape long and weakly flat, reaching beyond posterior margin of eye; antennomere 3 slightly longer than scape and distinctly longer than 4. Eyes large, transverse, coarsely facetted, slightly emarginate near antennal foramen; moderately separated dorsally. Submentum weakly emarginate at apex, mentum well exposed. Terminal palpomere of maxillary and labial palps elongate oval and apex slightly truncate. Pronotum sub rectangular, transverse, usually with slightly curved anterior margin; complete bead present on both anterior and posterior margins; lateral carina distinct with regular sharp teeth. Disc almost glabrous, rarely with very sparse and fine hairs, almost uniformly densely and coarsely punctate with very weakly elevated and shiny area medially. Prosternum coriaceous; hypomeron welldefined, broader than prosternal process. Prosternal process sub-parallel, strongly projecting beyond procoxae, narrowly pointed or rounded apically. Mesoventral process relatively narrow, emarginate at apex. Ventral side of thorax and coxae covered with golden hairs, ventral side of trochanter with erect golden setae. Metanepisternum weakly constricted at both ends. Scutellum rounded apically; surface with or without dense punctures. Elytral surfaces covered with irregular coriaceous sculpture, glabrous and usually shiny, with at least two weak traces of venation presenting on each elytron; elytral apices rounded with short sutural spine; epipleuron almost complete, narrowing apically. Legs strong; meso- and metatrochanter with patches of dense yellowish setae; femora sub-parallel, with two rows of sharp spines on ventral side; tibiae weakly expanded towards apex, surface rough and with rows of spines along outer margin, bearing sensory setae on ventral side apically; each tibia with two or three apical projections and a pair of subequal spurs; tarsi moderately strong; tarsomere 3 moderately lobed; tarsomere 5 shorter than tarsomeres 1 and 2 combined. Abdominal ventrites 1–4 covered by lighter tomentose pile separated from glabrous posterior patch on each ventrite by rows of long erected setae; lateral margin with complete carinae; setae present along the edge of ventrites 1–5, especially on the apex of ventrite 5. Male genitalia (Fig.14I). Tegmen longer than sternite VII; parameres length varies in different species, rounded apically with triangular projections at the base; penis as long as tegmen, dorsal apex emarginate while ventral apex narrowly rounded. <b>Female.</b> Body usually larger than male, length up to 80 mm. Antennae usually shorter than in male, filiform, only extending beyond elytral humeral angle; antennal scape about as long as antennomere 3 and distinctly longer than antennomere 4. Pronotal disc trapezoid with posterior margin broader than anterior margin; sexual setal patches absent on abdominal ventrites. Ovipositor (Fig. 15M) long; apical sclerosed part longer than half length of baculus, distal gonocoxites length and shape varies in different species, stylus moderately short and small, inserted laterally and relatively distant to gonocoxite apex, very weakly expanded apically. <b> <i>Remarks</i>.</b> Two species, <i>H. princeps</i> and <i>H. blackburni</i>, were originally included in <i>Cnemoplites</i> because of sexual patches on male abdominal ventrites. Our molecular results (Jin <i>et al</i>. 2020) revealed a long distance between them and the type species of <i>Cnemoplites,</i> and strongly indicated that the sexual abdominal patches evolved multiple times in the Prioninae history. Actually, these two species can be easily distinguished from <i>Cnemoplites</i> by the following characters: antennal scape shorter, only extending to the posterior margin of eyes; genal projections very sharp; pronotum more or less square with hypomeron relatively broader at anterior angle; female ovipositor with very small styli. One new species <i>H. mandibularis</i> sp. nov. (indicated as <i>Hagrides</i> sp 2 in Jin <i>et al</i>. 2020) is accordingly described here.
