Penthicodes (Ereosoma) bimaculatus (Schmidt, 1905)

( Figs 2 , 5A–D , 6A–C , 7A , 9A )

Diagnosis. The external morphology of the species is close to P. (Ereosoma) celebicus and P. (Ereosoma) rugulosus that are known from Indonesia (Sulawesi) and Philippines, respectively. They share the characters of a white patch along the sutural margin on nodal line of cross-veins and irregular black-brown markings on tegmina, but the disc of the hind wing is red with orange apically in P. (Ereosoma) bimculatus . The male genitalia of this species differ from other species by these charac- ters: anal tube short with lateral curved expansion direct- ed ventrally ( Fig. 5B, D ); gonostyli slightly elongated, round at apex in lateral view.

Material examined. Thailand: 2 ♀♀, Yala Prov., Betong Dist. , 24.VIII 2018, M. Naiduang- chan & P. Pawangkhanant leg., THNHM-I-24962 and THNHM-I-24963 ( THNHM) ; 1 ♂, Yala Prov., Betong Dist. , 3.VIII 2020, P. Pawangkhanant leg., THNHM-I-24961 ( THNHM) .

Material examined from photographs. Malaysia: 1 specimen ( Fig. 6A ), Selangor, Semenyih , 2.9474° N, 101.8451° E, 24.V.2020, T. Eng Wah ; 1 specimen ( Fig. 6B ), Selangor, Sungai Tua , 3.25233° N, 101.67538° E, 10.XII.2016, T. Eng Wah ; 1 specimen ( Fig. 6C ), Selangor, Ulu Yam , 3°25′59″ N, 101°39′27″ E, 9.VI.2012, H.P. Guek .

Distribution. Borneo, Indonesia (Sumatra), West Malaysia (new country record), Singapore and Thailand ( Constant 2010; Bourgoin 2022).

Biology. Specimens (male and female) of P. (Ereosoma) bimaculatus have been confirmed from Thailand and Peninsular Malaysia. This species is confined to Sunda- land. So far, the northern limit in its distribution range is in the southernmost part of Thailand. The male specimen was collected from southern Thailand on a trunk of Shorea cf. curtisii ( Dipterocarpaceae ) together with a cockroach ( Fig. 7A ).
