Additional material examined. VIETNAM: 1 spec. ( FEFU), Hanoi Hotel Kim-lien , 1–2.V.1966, Exp. Gy. Topál, Nr. 245, from decaying banana tree, Dactylosternum abdominale (Fabricius) , Det. M.

Diagnosis. Length 4.4–5.0 mm, maximum width 2.5–2.8 mm. Body oblong oval, anterior half of elytra nearly parallel-sided ( Fig.1 View FIGURES 1–4 ); elytra weakly convex.Dorsal black to dark brown.Anterior margin of clypeus without marginal rim. Clypeus, posterior margin of vertex and lateral portion of pronotum with distinct mesh-like microsculpture between punctures ( Fig. 47 View FIGURES 39–47 ). Antenna yellow-brown, with club black to yellow-brown, club compact ( Fig. 40 View FIGURES 39–47 ). Elytron with sutural stria and 10 rows of serial punctures, all nearly reaching elytral base. Aedeagus ( Fig. 20 View FIGURES 20–24 ) ca. 1 mm long. Phallobase ca. 0.6× as long as parameres. Parameres slender, mostly membranous in apical half, truncate and widened apically; the widening is often not distinct due to modification of membranous apex during preparation or due to an intraspecific variation. Median lobe shorter than parameres, ca. 0.7× as long as parameres, moderately stout, elongate, triangular, tapering towards apex; apex of median lobe abruptly tapered with rounded apex. Gonopore situated subapically.

For detailed description see Smetana (1978) and Hansen (1991).

Biology. ( Figs. 65, 67 View FIGURES 64–69 ) Found in various types of decaying organic matter, such as rotting plant tissues, domestic waste or farmyard manure, in China often associated with decaying trunks of banana plants and the farmyard manure. Adult individuals are attracted by light .
