Sparedrus latipennis ( Pic, 1923) comb. nov.

( Figs. 10 , 13, 21)

Sparedropsis latipennis Pic, 1923: 22 .

Type locality. Northern Vietnam, Hai Phong province, Hạ Lüng, ca 10 km W Haiphong.

Type material examined. SYNTYPE (? HOLOTYPE): ♀, ‘Há-Lang [= Hạ Lüng, ca 10 km W Haiphong], Tonkin nord [= northern Vietnam] [handwritten] // Sparedropsis latipennis n. sp. [Pic’s handwriting] // type [yellow label, Pic’s handwriting] // type [red label, printed] // Muséum Paris, coll. M. Pic [printed]’ ( MNHN).

Redescription. Coloration. Body entirely terra-cotta to rusty, only apices of femora very narrowly sepia ( Fig. 10 ).

Male unknown.

Female. Eyes large, only slightly protruding, head across eyes ca. as wide as pronotum, behind eyes straight, nearly parallel-sided. Frons between eyes less than three times as wide as length of antennomere 2 (Fig. 13). Last maxillary palpomere narrowly securiform. Antenna slightly exceeding two thirds of elytral length, antennomeres 3-10 more or less serrate with arcuate inner margin and protruding inner lateroapical corner, antennomeres 6-11 more or less flattened dorsoventrally, more or less curved, antennomeres 9-10 as in Fig. 21 . Surface of head densely punctate on vertex, more sparsely between eyes, with sparse, long, semierect yellow pubescence, matt to semilustrous. Pronotum ca. one sixth longer than wide, its anterior margin slightly but distinctly sinuate, anterior corners slightly rounded, lateral margins almost straight, moderately converging posteriorly, posterior corners obtuse, posterior margin rounded. Surface of pronotum punctate and pubescent like that of head, matt, semilustrous before base, very shallow mediolongitudinal depression reaching from one third of pronotal length to basal margin. Elytra parallel-sided, their surface finely punctate, semilustrous, with semierect, fine yellow pubescence, elytral nervation very slightly indicated. Last tergite slightly exceeding last sternite, with small triangular apical emargination; apex of last sternite rounded.

Length (♀). 15.5 mm.

Comments. Because the male is unknown, the 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. atricolor ( Pic, 1935) .

Distribution. Northern Vietnam.
