[4] Parena (Crossoglossa) obenbergeri Jedlička, 1951

Habitus: Fig. 20A . Male genitalia: Fig. 20B .

Jedlička, 1952: 210 (type locality: Java; holotype in NMPC).

Type material examined. Parena obenbergeri Jedlička : Holotype (NMPC, Fig. 20 ), male, body length = 9.9 mm, " g. Roesa / Java ", "TYPUS" [red label], " Obenbergeri / sp. n. / det. ING. JEDLIČKA" [pink label].

Non-type material examined. 1 female (NNML), " Nederland Indie / Java 1800'-2400' / Tjiajoenan / Soekanegara / eind kot. 1941 / J.M.A.v. Groenendael". 1 ex (NHML), "Bato-raden / G. Slamat. Java / F.C. Drescher. / 9.VI.1938 "; " Andr. / FCD / 201 "; " Parena / mellea/? Chd. / H.E. Andrewes det."; "H.E. Andrewes Coll. / B.M. 1945-97".

Comparisons. P. obenbergeri is very similar to P. laesipennis . It differs from the latter species only in having the elytral apical truncation more distinct and the outer apical angles sharper. However, with the male genitalia of P. obenbergeri having the apical lamella distinctly narrower than in P. laesipennis and the wide distributional gap between them, we treat it as a distinct species.

Description. Body length 9.9 mm. Dorsum reddish brown; basal three antennomeres, and basal half of antennomere 4 reddish brown, rest parts of antennae nearly black; venter brown. Pronotum strongly transverse, PW/PL = 1.60, slightly wider than head including eyes, PW/HW = 1.08; lateral explanations very wide. Elytra without microsculpture; striae not incised, replaced by lines of fine punctures; intervals completely flat, very finely and sparsely punctate; disc depressed near middle of intervals 3 to 6, depressions subtriangular; apical truncation distinct, straight, outer apical angles well angulate, forming distinct obtuse angles; sutural angles pointed, forming short spines. Median lobe of aedeagus gradually narrowed to apex, ventral margin almost straight; apical lamella slightly bent to dorsum, length 1.75 folds as its basal width, apex rounded. Endophallus very densely scaled on basal sheath, base of apical sheath ovate in dorsal view; squamate sac indistinctly divided, on basal fifth of median lobe, right to squamate sheath. Female ovipositor not studied.

Distribution ( Map 3 , green). Only known from the western part of Java.
