Redescription. Male (n = 3, Figs 1–2, 29): LB = 11.0–13.0 mm, WB = 4.5–5.2 mm.
Body black, with long sparse suberect black and partly white hairs on dorsal surface, beneath antennomeres, and legs. Head, pronotum, and elytra mostly with black pubescence, spotted with whitish and/or yellowish cream white pubescence which are concentrated and formed wide vague transverse band in apical 1/4 of elytra. Antenna without tuft of hairs; antennomere I sparsely spotted with white pubescence; antennomere II, each basal part of III– VII, and entire part of VIII–X with white pubescence, and the remainders with black pubescence. Ventral surface clothed with whitish and/or light yellowish pubescence intermixed with sparse white hairs. Legs with femora irregularly spotted with whitish and/or light yellowish pubescence; tibiae with same pubescence on basal and middle parts.
Eye subdivided into upper and lower lobes which are connected posteriorly by narrow line without ommatidium, LL/WL = 1.2–1.4, LL/LG = 1.2–1.4. Antenna 1.3–1.4 times as long as body length; relative lengths of each antennomere from I to XI as follows: 1.5: 0.3–0.4: 1.9–2.0: 1.3–1.4: 0.9–1.0: 0.8: 0.7–0.8: 0.6: 0.6: 0.5–0.6: 0.4–0.5; antennomeres III and VI slightly dilated inwardly at each apex. Pronotum LP/WP = 0.7, WP/ WEH = 0.7, constricted and transversally depressed near base and apex, with pair of obtuse indistinct swellings on disk. Elytra LE/BL = 0.7, LE/WEH = 1.7, LE/LP = 3.4–3.6, almost parallel-sided on basal 3/4, arcuately narrowed and rounded apically; disk with sparse granules on base, irregularly with fine punctures which are rough, distinct in basal half and reduced apically.
Male genitalia as in Figs 53–60. Tegmen in dorsal view widest behind middle, gently curved in lateral view; paramere in dorsal view thick, ca. 1/4 length of tegmen, gently and arcuately narrowed toward rounded apex, with setae arising from apical half on latero-dorsal side and concentrated apically; ringed part in dorsal view expanded laterally behind middle of tegmen, thence gently narrowed basally. Median lobe in dorsal view thick, gently curved in lateral view; apex of ventral plate bluntly pointed; basal strut dehiscent from near middle of median lobe. Endophallus almost 3.5 times as long as median lobe; BPH subequal to half-length of median lobe, with pair of CS; MPH with MT+CT curved near distal 1/3, with MSp and LSp; PB cylindrical in proximal 2/3, roundly swollen together with APH in distal 1/3, with SSp; APH short, with AA on dorsal side and ED on AA; MSp minute, sparsely arranged in proximal 3/4 of MT+CT; LSp small, unidentate, evenly and densely distributed on distal 1/4 of MT+CT; SSp minute, densely covered dominant area of PB, somewhat sparser in proximal part.
Female (n = 4, Figs 3–4, 30): similar to male. LB = 12.0– 16.6 mm, WB = 4.8–6.4 mm. Body relatively thick. Lower eye lobe relatively small, LL/WL = 1.2–1.3, LL/LG = 1.0–1.1. Antenna relatively thick and short, 0.9–1.2 times as long as body length; relative lengths of each antennomere from I to XI as follows: 1.7–2.1: 0.4–0.5: 2.3– 2.5: 1.6–1.7: 1.0–1.2: 0.6–0.7: 0.5–0.6: 0.4–0.5: 0.3–0.4: 0.3: 0.2–0.3; antennomere IX–XI with black pubescence.
FIGURES 1–8. Habitus of Metipocregyes spp. 1–4, M. nodieri; 5–8, M. affinis; 1–2, 5–6, male; 3–4, 7–8, female; 1, 3, 5, 7, dorsal view; 2, 4, 6, 8, lateral view.
Diagnosis. This species is distinguishable from other congeners by the following features: head, pronotum, and elytra mostly with black pubescence, spotted with white and yellowish pubescence which are concentrated and formed a wide vague transverse band in apical 1/4 of elytra; antenna without tuft of hairs.
Distribution. North Vietnam (Ha Giang and Vinh Phu), South China (Guangxi and Yunnan).
Remarks. This is the type species of this genus. Prior to this work, it was known only from the type locality. This is the first record from China and a new locality in Vietnam.
