Note on Otraleus hypsimelathrus Günther, 1935

Otraleus hypsimelathrus Günther, 1935: 28 (description), pl. 2, fig. 18 (dorsal aspect of habitus).

Otraleus hypsimelathrus – Günther 1938: 59 (list). — Hennemann 1998: 122 (list). — Zompro 2005: 267 (type data). — Otte & Brock 2005: 242 (type data). — Seow-Choen 2016: 199 (notes on holotype).

To supplement Günther’s (1935) original description, we provide illustrations of the holotype along with a distribution map for the species which is so far known from a single location in Sulawesi ( Fig. 1 ). Currently only the male is known.

Males of O. hypsimelathrus Günther, 1935 can be separated from the four newly described Philippine species of Otraleus by the following combination of characters:

1. Abdominal terga II–VIII with definite lobes postero-laterally.

2. Ventral portion of thorax black.

3. Apterous.

4. Mesonotum, median segment and abdominal terga at best with an indefinite hump posteromedially.
