Teispes Thomson, 1864

( Figs. 13 D–F, 15A , 15P , 18C )

Teispes Thomson, 1864: 304 . Type species Teispes dorsalis Thomson, 1864 (= Mallodon insulare Hope, 1842 ), by monotypy.

Teispes: Lacordaire, 1868: 111 ; Lameere, 1903a: 8; Lameere, 1919: 22.

Diagnostic combination (Male). Large beetles, 35–55 mm long. Head and pronotum black, elytra brown or light brown. Sexually dimorphic dense fine punctures present near lateral margin of pronotum and most of ventral side of prothorax. Head slightly narrower than prothorax; frontoclypeal suture straight to broadly angulate; median groove complete. Antennal tubercles almost flat, rounded apically. Eyes transverse, weakly emarginate near antennal insertion, broadly separated dorsally. Mandibles 2/3 of head capsule length, sexually dimorphic, not bending towards ventral side and unidentate apically. Antenna reaching to middle of elytra. Scape about 1/4 of head length, posteriorly not reaching posterior margin of eye, gradually expanded apically; antennomere 3 as long as scape or antennomere 4. Mentum not fused to sub-mentum, constricted underneath sub-mentum and not visible ventrally. Terminal palpomere of maxillary and labial palps oval and apically weakly truncate. Prothorax transverse with lateral carina moderately strongly dentate; anterior and posterior margins with complete bead. Pronotal disc mostly shiny, with fine and dense punctate, slightly depressed lateral irregular areas. Prosternal process sub-parallel, extending to mesoventrite, rounded apically. Elytral surface shiny with irregular coriaceous sculptures; inner apical angle with short spine. Legs moderately strong, rows of small spines present on all femora and protibia. Protibia with two sharp apical projections and pair of subequal spurs; tarsomere 3 moderately lobed, tarsomere 5 as long as tarsomeres 1 and 2 combined.

Description. Male. Length 35–55 mm. Dorsum glabrous and shiny; head and pronotum black, elytra uniformly reddish brown to dark brown. Head oval, slightly narrower than pronotum. Mandibles much longer and stronger in males; dorsum bearing short setae, apex curved inwards; each mandible wedgeshaped, 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 relatively dense setae; labrum separated from clypeus by a deep groove; dorsal surface of clypeus with sparse short setae. Frontoclypeal suture almost broadly angulate; median groove distinct and complete. Antennal tubercles relatively flat, very distant to each other, apex rounded. Antennaa 11-segmented, filiform, extending to middle of elytra; scapes short, slightly longer than eye. Eyes transverse, coarsely facetted, very weakly emarginate near antennal foramen; broadly separated dorsally. Submentum weakly curved at apex, mentum restricted and not visible ventrally. Terminal palpomere of maxillary and labial palps oval and apically rounded. Pronotum transverse, width 2.5 times of length, with anterior margin emarginate medially; complete bead present on both anterior and posterior margins; lateral carina distinct and dentate. Disc shiny, glabrous and with sparse punctures medially; lateral and anterolateral area with deep and fine punctures. Prosternum bearing uniformly deep fine punctures; hypomeron well-defined, slightly broader than prosternal process; prosternal process sub-parallel, projecting towards mesoventrite, narrowly rounded apically. Mesoventral process relatively broad, apex emarginate medially. Ventral side of pterothorax and coxae covered with golden hairs, shiny and glabrous arrow-shapped area present in central part of metaventrite. Metanepisternum slightly broader posteriorly, but sharply constricted at base. Scutellum broadly rounded at apex, surface smooth and shiny. Elytral surfaces shiny with very fine and weak irregular coriaceous sculpture, two or three traces of venation present; elytral apices rounded with small sutural spine; epipleuron complete. Legs strong, femur broad and relatively flat, constricted at both ends, surface smooth, ventral side with several tiny spines; each tibia with distinct apical projections and a pair of subequal spurs; tarsi relatively strong; tarsomere 3 moderately lobed; tarsomere 5 longer than tarsomere 1 and 2 combined. Abdominal ventrites smooth, only bearing dense long setae along the edge, especially on the apex of ventrite 5. Male genitalia ( Fig. 15A ). Tegmen longer than sternite VII; parameres moderately long, 0.15 times length of entire tegmen, truncate apically with small triangular projections at the base; penis about as long as than tegmen, dorsal apex broadly rounded while ventral apex narrowly pointed.

Female. Mandibles much shorter than in males. Pronotum weakly emarginate at anterior margin; anterior angles prominent; lateral carina with longer lateral spines. Pronotal surface coarsely punctate, punctures coarser and irregular in lateral area; prosternum and hypomeron with sparse fine punctures and loose hairs, relatively shiny. Ovipositor ( Fig. 15P ) moderately long, apical sclerosed part 2/3 of baculus length; distal gonocoxites short and small; stylus inserted laterally and close to gonocoxite apex, relatively long and gradually expanded apically.
