Description

Sparedrus atricolor (Pic, 1935) comb. nov.

(Figs. 8, 12, 18-19)

Sparedropsis atricolor Pic, 1935: 100.

Type locality. Northern Vietnam, Tuyên Quang province, Chiêm Hóa and Tuyen Quang regions.

Type material examined. SYNTYPE (? HOLOTYPE): ♀, ‘Museum Paris, Tonkin centr. [northern Vietnam], région de Chim-Hoa [= Chiêm Hóa] et de Tuyen-Quan [= Tuyên Quang], A. Weis 1901 [yellow label, printed] // Printemps [printed] // Sparedropsis unicolor [Pic’s handwriting], M. Pic det. [printed] // type [red label, printed]’ (MNHN).

Redescription. Coloration. Head sepia, palpi and antennae terra-cotta, thorax, elytra and ventral side of abdomen sepia, legs terra-cotta with knees narrowly sepia (Fig. 8).

Male unknown.

Female. Eyes large, very slightly protruding, head across eyes about as wide as pronotum, straight behind eyes, very slightly narrowing posteriorly. Frons between eyes ca. four times as wide as length of antennomere 2 (Fig. 12). Last maxillary palpomere narrowly securiform. Antennomeres 2-3 as in Fig. 18, antennomeres 6-11 missing in the examined specimen, antennomeres 4 and 5 moderately serrate, with slightly protruding inner apical corner. Surface of head finely and densely verrucose, matt, between eyes more sparsely structured, semilustrous, with sparse, long, semierect yellowish-white pubescence. Pronotum moderately longer than wide, moderately cordiform, anterior margin very slightly sinuate, nearly straight, anterior corners rounded, lateral margins rather sinuately converging posteriorly, posterior corners obtuse, posterior margin rounded. Surface of pronotum sculptured and pubescent like that of head, matt, semilustrous both near anterior and posterior margin, with very shallow median depression before midlength. Elytra parallel-sided, their surface finely punctate, semilustrous (left elytron, right one is teratologically sculptured, roughly verrucose, matt), with fine, semierect, yellowish-white pubescence, elytral nervation slightly indicated. Last tergite moderately exceeding last sternite, with triangular apical emargination (Fig. 19), apex of last sternite rounded.

Length (♀). 18.3 mm.

Distribution. Northern Vietnam.

Comments. Because the male is unknown, this species cannot be included in any species group. Owing to its large body and habitus, it is probably related to S. subserratus (Gressitt, 1939) and S. latipennis (Pic, 1923).
