( Fig. 76 )

Lithocharis preangeranus [sic] CAMERON, 1936: 50.

Type material examined: Holotype ♀: " JAVA. F.C. Drescher. B.M. 1934-264. / F.C. Drescher, lamp. Preanger, Bandoeng-Dago , 8.IX.1929 / Lithocharis preangeranus Cam , Type / Holo-Type / Holotype Lithocharis preangeranus Cam. , det. R.G. Booth 2014 / Lithocharis preangerana Cameron , det. V. Assing 2015 " ( BMNH).

Comment: The original description is based on "A single ♀ " from "Dago, Bandoeng" ( CAMERON 1936). The generic assignment is uncertain and requires confirmation based on males.

Redescription: Body length 4.5 mm; length of forebody 2.2 mm. Coloration: head dark-brown; pronotum reddish; elytra pale-reddish, with a large infuscate spot in posterior half, this spot narrowly separated from suture and posterior margin of elytra; abdomen brown, with segments VIII-X and the anterior, lateral, and posterior margins of segments III-VII reddish; legs yellow; antennae reddish.

Head ( Fig. 76 ) weakly transverse, 1.04 times as broad as long, weakly narrowed behind eyes; posterior angles marked; punctation extremely dense and fine. Eyes large, slightly longer than postocular region in dorsal view. Antennae 1.4 mm long; preapical antennomeres approximately as long as broad.

Pronotum ( Fig. 76 ) 1.02 times as wide as long and 1.1 times as broad as head; posterior angles moderately marked; punctation similar to that of head, disc matt; midline with narrow glossy band not quite reaching anterior and posterior margins of pronotum.

Elytra ( Fig. 76 ) as long as pronotum; punctation very dense and fine; surface matt. Protarsomeres I-IV unmodified. Metatarsomere I approximately as long as the combined length of II and III.

Abdomen narrower than elytra; punctation extremely fine and dense; interstices with microreticulation; posterior margin of tergite VII with palisade fringe.

♂: unknown.

Comparative notes: This species is characterized particularly by the marked posterior angles of the head and the coloration of the elytra.

Distribution: Lithocharis preangerana is currently known only from Java.
