Berosus megaphallus Oliva & Short 2012

Body length: 6.0–7.7 mm. Shape elongate, depressed, not very narrow. Eyes prominent, a little more in males. Maxillary palpi slender, rather long, a little more so in males because the apical segment is longer and more slender than in females. Dorsum of head, pronotum, scutellum, and elytra testaceous, except slightly darkened on base of frons, a pair of narrow paramedial bands on pronotal disc, and small elytral spots in the usual pattern. Venter of thorax and abdomen dark brown; maxillary palpi darkened at tip of apical segment; femora with pubescent portion darkened, glabrous portion testaceous. Dorsal sculpture moderate to fine, regular; punctures round, only on the base of frons a little elliptical. Head and pronotum with punctures about twice the size of an ommatidion; micropunctures about one-sixth the size of punctures. Elytral striae deep, well-impressed, finely punctured. Interstriae flat, wide, with moderate-sized punctures disposed in several series, on posterior half of elytra a little coarser and bearing spine-like hairs. Elytral micropunctures fine, on posterior half obsolete. Elytral apices emarginate, with acute parasutural spine; in males sutural angle broadly rounded, comprising the three inner striae; in females the emargination a little broader and the sutural angle produced into a short straight spine. Mesoventral process laminar, with large, curved, but not acute, anterior tooth, behind the margin obliquely lowered. Metaventral process narrow, with small median depression; posterolateral angles produced into triangular laminae, posterior angle not raised. First ventrite carinate medially only between metacoxae, with deep, moderately large lateral depressions. Fifth ventrite with shallow apical notch in females, in males raised into a disc around a narrow, very deep notch (Fig. 21B). Lateral margins of abdominal ventrites smooth. Meso- and metafemora with pubescence on basal three-fifths and three-quarters respectively. Male protarsi with the two basal tarsomeres thickened, bearing adhesive soles; first about twice as long as second, fourth slender, longer than 3 basal segments taken together. All claws long, slender, very weakly curved. Male genitalia: Basal piece about two-fifths of total length. Parameres complex, in lateral aspect with wide blunt apices, with membranous appendices in a ventral position. Median lobe much shorter than parameres, a little shorter than the appendices (Fig. 21B).
