( Figs. 11 , 22 )

Sparedropsis angustatus Pic, 1923: 22 .

Type locality. Cambodia, Kâmpóng Kesley (uncertain, hardly readable).

Type material examined. SYNTYPE (? HOLOTYPE): ♀, ‘ Cambodge, Kampong [= Kâmpóng] Kesley [uncertain, hardly readable, Pic’s handwriting] // pas coll. Frm. [= Fairmaire] [Pic’s handwriting] // type [yellow label, Pic’s handwriting] // type [red label, printed] // Sparedropsis angustatus n.sp. [Pic’s handwriting] // Muséum Paris, coll. M. Pic [printed]’ ( MNHN).

Redescription. Coloration. Body entirely rusty ( Fig. 11 ).

Male unknown.

Female. Eyes large, slightly protruding, head across eyes ca. as wide as pronotum, behind eyes narrowing posteriorly in an almost straight line. Frons between eyes about 1.5 times as wide as length of antennomere 2. Last maxillary palpomeres missing in examined specimen. Antenna presumably moderately exceeding elytral midlength (both last antennomeres missing in examined specimen), antennomeres 3-10 more or less serrate with inner margin arcuate and inner lateroapical corner protruding, antennomeres 6-10 more or less flattened dorsoventrally, more or less curved, antennomeres 9-10 as in Fig. 22 . Surface of head densely verrucose on vertex, matt, sparsely punctate between eyes, semilustrous, with long, semierect yellow pubescence. Pronotum ca. as long as wide, anterior margin straight, very slightly sinuate in middle, anterior corners rounded, lateral margins straight, nearly paralell-sided, slightly sinuate before obtuse posterior corners, posterior margin rounded. Surface of pronotum sculptured and pubescent like that of vertex, matt, with indistinct, impunctate, narrow mediolongitudinal line situated in posterior two thirds of pronotal length. Elytra parallel-sided, their surface finely punctate and yellow pubescent, semilustrous, elytral nervation absent. Last tergite not exceeding last sternite, both rounded apically.

Length (♀). 10.6 mm.

Differential diagnosis. Because the male is unknown and the last palpomeres are missing in the examined specimen, it cannot be included in any species group. It might even be a female of S. rufus , which is the habitually most similar species.

Distribution. Cambodia.
