description: <i>Cryptipus</i> Jin, de Keyzer et &amp;Sacute;lipi&amp;nacute;ski, 2020 (Figs. 5 J–M, 14G, 15J, 17B) <i>Cryptipus</i> Jin, de Keyzer et &amp;Sacute;lipi&amp;nacute;ski, 2020: 19. Type species <i>Teispes frenchi</i> Blackburn, 1892, by original designation and monotypy. <b> <i>Diagnostic combination (Male)</i>.</b> Large beetles, 25–50 mm long. Dorsum uniformly reddish brown to dark brown. Sexually dimorphic dense fine punctures present near lateral margins of pronotum, ventral side of prothorax and mesoventrite. Head as broad as prothorax; frontoclypeal suture arcuate or broadly angulate; median groove complete. Antennal tubercles almost flat, rounded apically. Eyes transverse, weakly emarginate near antennal insertion, relatively distant dorsally. Mandibles shorter than head, sexually dimorphic longer and thicker in male than in female, weakly arcuate and unidentate apically. Antenna reaching mid elytra in males. Scape about half of head length, posteriorly not extending to posterior margin of eye, gradually expanded apically; antennomere 3 shorter than scape and about as long as 4. Mentum not fused to submentum (Fig. 5M). Terminal palpomere of maxillary and labial palps weakly expanded and apically round- ed. Prothorax transverse with lateral carina weakly dentate; anterior margin without bead, posterior margin with complete bead. Pronotal disc shiny and almost smooth medially surrounded by large and deep, sometimes merged punctures laterally and posteriorly separating disc from irregular lateral densely punctate areas. Prosternal process weakly expanded beyond procoxae, extending to mesoventrite, narrowly pointed apically. Elytra surface almost glabrous and shiny; inner apices with acute sutural angles. Legs strong, rows of tiny spines present on femora while absent on tibia. Protibia smooth externally with two sharp apical projections and pair of subequal spurs; lobes on tarsomere 3 narrow and short, tarsomere 5 much longer than tarsomeres 1 and 2 combined. <b> <i>Description</i>. Male.</b> Length 25–50 mm. Dorsum globrous and shiny, uniformly reddish brown to dark brown. Head oval, slightly narrower than pronotum. Mandibles about as long as head capsule, dorsally bearing sparse hairs, apex curved inwards; each mandible wedge-shaped, very thick and strong on lateral side and near the base, unidentate at apex, with one extra tooth 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 long setae. Frontoclypeal suture almost arcuate or broadly angulate; median groove distinct and complete. Antennal tubercles relatively flat, very distant to each other, apex rounded. Antennae 11-segmented, filiform, extending to mid elytra; scapes short, as long as eye length. Eyes transverse, coarsely facetted, very weakly emarginate near antennal foramen; relatively distant dorsally. Submentum weakly curved at apex, mentum well exposed; gular area triangular and coarsely punctate. Terminal palpomere of maxillary and labial palps weakly expanded and apically rounded. Pronotum transverse with anterior margin emarginate medially; anterior margin without bead, posterior margin with complete bead; lateral carina weakly dentate. Disc surface shiny, glabrous and smooth medially, with deep and fine punctures on lateral area and two small patches of coarsely punctate area posteriorly. Prosternum bearing uniformly deep fine punctures; hypomeron well-defined, broader than prosternal process; prosternal process moderately expand beyond procoxae, with median lobe projecting towards mesoventrite, narrowly rounded apically. Mesoventral process relatively broad, apex emarginate medially. Ventral side of pterothorax and coxae covered with golden hairs. Metanepisternum constricted at base. Scutellum narrowly rounded at apex, surface smooth and shiny. Elytra shiny with very fine and weak irregular coriaceous sculpture, three traces of venation present on apical half of elytra; elytral apices rounded with small but sharp sutural angulation; epipleuron almost complete, very narrowing apically. Legs strong, femur broad and relatively flattened, weakly constricted at both ends, ventral side with rows of tiny spines; each tibia with two distinct apical spines and a pair of strong spurs. Tarsi slender; tarsomere 3 with narrow and short lobes; tarsomere 5 much longer than tarsomere 1 and 2 combined. Abdominal ventrites smooth, only bearing dense long setae along the edges, especially on the apex of ventrite 5. Male genitalia (Fig. 14G). Tegmen longer than sternite VII; parameres short, less than 0.1 times length of entire tegmen, truncate apically with small triangular projections at the base; penis longer than tegmen, dorsal apex broadly rounded while ventral apex narrowly pointed. <b>Female.</b> Mandibles much shorter and narrower than in male; pronotum weakly constricted near anterior margin, with coarsely punctate, irregular lateral area devoid of very sense punctation; prosternum and hypomeron with sparse fine punctures and sparse hairs, relatively shiny. Ovipositor (Fig. 15J) long, apical sclerosed part half of baculus length; distal gonocoxites short and small; stylus inserted laterally and close to gonocoxite apex, relatively long and gradually expanded apically. <b> <i>Remarks</i>.</b> <i>Cryptipus</i> can be distinguished from the remaining genera of the Australian Macrotomini by having the uniformly reddish-brown body, relatively glabrous and smooth elytra, surface only with very fine and shallow punctures usually very hardly seen, the elongate tarsomere 5, which is longer than tarsomeres 1–3 combined, and the tibia without any teeth or spines along external margins. Males are recognised by longer and stronger mandibles. <i>Cryptipus</i> is currently regarded as a monotypic genus to include single Australian species described as <i>Teispes frenchi</i> by Blackburn (1892) and subsequently transferred to <i>Archetypus</i> by Lameere (1903a). Our molecular results (Jin <i>et al</i>. 2020) revealed a relatively isolated placement for this species, hence it was placed in a separate genus.
