Chelonocoris usingeri Kormilev, 1956

( Figs 1 , 4–8 , 19 )

Chelonocoris usingeri KORMILEV, 1956: 287 .

Material studied: Holotype, female ( HNHM): “Borneo / Xántus // Holotype // Chelonocoris usingeri / N. Kormilev 1955”.

Notes: In the original description the female holotype was described, and only the tip of abdomen was figured. Now habitus drawings from two different directions, and a photo of the holotype and its antenna is given. Some features of this specimen are compared to those of Ch. bakonyii sp. n. under the latter species.

KORMILEV (1956) gave the proportions of the antennal joints erroneously as 20:11:22:8, (obvious misspelling for joint I), they are as 70:22:40: 16 in my measurements.

Note on type locality: János Xántus, an early Hungarian explorer, hunt- er, ethnographer and geographer performed a collecting trip from January to May 1870 in the northern territories of Borneo , debarking in Sarawak ( SÁNDOR 1970). Thus, the approximate time and locality of collecting can be added .
