description: Metipocregyes brunneatus sp. nov.
(Figs 17–20, 37–38, 82–88)
Type locality. Bao Loc, Lam Dong Prov., Vietnam
Type series. Holotype: ♂ (EUMJ, Figs. 17–18, 37, 82–88): “[South Vietnam] / Bảo Lộc / Lam Dong Prov. / 23–25. IV, 2000 / J. Yamasako coll.”. Paratypes: 1♂ 1♀ (CJY, Figs 19–20, 38), same locality and collector as the holotype, 5– 7. V, 1999; 1♂ (CJY), same data as the holotype; 1♂ 1♀ (CST), same locality, 21–22. V, 2000, Masao Ito leg.
Description. Male (n = 4, Figs 17–18, 37): LB = 13.8–15.8 mm, WB = 5.0– 5.6 mm.
Body dark brown except for antenna and legs which are reddish brown, or entirely reddish brown, with sparse black or brown hairs on dorsal surface, beneath antennomeres, and legs. Head, pronotum, elytra, and ventral surface clothed with brown pubescence, and partly spotted with white pubescence. Antenna with antennomere I partly clothed with same pubescence as head; antennomere II and each basal area of III–XI with light brown or white pubescence, and the remainders with brown pubescence. Elytra each scattered with small black spots, with markings of black pubescence arranged into transverse zigzag bands behind base and before and behind middle. Legs with each femur with brown and light brown or white pubescence; each tibia with same pubescence on base and middle; tarsomeres I–II and middle of claws with same pubescence; the remainders with brown pubescence.
Eye deeply emarginate; upper and lower lobes connected posteriorly by 2–4 rows of ommatidia; lower lobe large, LL/WL = 1.1, LL/LG = 1.5–1.9. Antenna 1.2–1.3 times as long as body length; relative lengths of each antennomere from I to XI as follows: 1.6–1.7: 0.3: 2.0: 1.3–1.4: 0.9–1.0: 0.8: 0.7: 0.6–0.7: 0.6: 0.5–0.6: 0.4– 0.5; antennomeres III slightly dilated inwardly at apex. Pronotum LP/WP = 0.7, WP/WEH = 0.7, constricted near base and transversally depressed before apex, with granules on dorsal surface and pair of obtuse swellings on middle of disk. Elytra LE/LB = 0.7, LE/WEH = 1.9–2.0, LE/LP = 3.6–4.0, almost slightly and evenly narrowed toward apical 1/5, arcuately narrowed and rounded apically; disk granulate in basal 1/5, with punctures rough and distinct in basal half but reduced apically.
Male genitalia as in Figs 82–88. Tegmen in dorsal view widest near middle, gently curved in lateral view; paramere in dorsal view thick, ca. 1/4 length of tegmen, gently and evenly narrowed toward rounded apex, with setae arising from apical half on latero-dorsal side and concentrated in apical area, and with short setae on base of ventral side; ringed part in dorsal view expanded laterally near middle of tegmen, thence gently narrowed basally. Median lobe in dorsal view thick, gently curved in lateral view; apex of ventral plate roundly pointed; basal strut dehiscent from just before middle of median lobe. Endophallus almost triple length of median lobe; BPH subequal to half-length of median lobe, with pair of CS; MPH with MT+CT curved near distal 1/4, with MSp and LSp; PB cylindrical in proximal 2/3, roundly swollen together with APH in distal 1/3, with SSp; APH short, with ED proximally, without AA; MSp minute, indistinct, very sparsely arranged in proximal 2/3 of MT+CT; LSp small, unidentate, densely distributed mainly in distal 1/3 of MT+CT; SSp minute, densely covered dominant area of PB, somewhat sparser in dorsal side of proximal part.
Female (n = 2, Figs 19–20, 38): very similar to male. LB = 16.5–17.7 mm, WB = 6.2–6.7 mm. Antenna 1.0– 1.1 times as long as body length; relative lengths of each antennomere from I to XI as follows: 1.7–1.9: 0.3–0.4: 2.1–2.3: 1.6–2.0: 0.9–1.0: 0.7: 0.6: 0.4–0.5: 0.4: 0.4: 0.3–0.4.
Diagnosis. This species is unique within the genus and easily distinguished from congeners by a combination of the following features: body clothed with brown pubescence; eye deeply emarginated and the lobes connected posteriorly by 2–4 rows of ommatidia; lower eye lobe large.
Distribution. South Vietnam (Lam Dong).
Etymology. The specific epithet is attributable to its dominant color of pubescence on the body surface.
