Diagnosis

Platybinthus punctatus gen. et comb. nov. differs from Platybinthus striolatus gen. et comb. nov. by larger size, and female copulatory papilla with apex narrowed and bilobed (instead of narrowed and obtusely rounded). Only faint differences of female FW venation and colouration with Platybinthus sandyi gen. et sp. nov.

Material examined

Syntype INDONESIA – Maluka • 1 ♀; Halmaheira [= Halmahera Island ]; 1894; W. Kükenthal leg.; molecular sample L176; GenBank accession: OP684789 and OP686541 ; MNHN-EO-ENSIF1448 .

Additional specimens INDONESIA – Maluka • 1 ♀; Halmahera [Island], Gamkonora ; 4 May 1931; G. Heinrich leg.; MNHN- EO-ENSIF1430 .

Remark

The only type specimen examined from the original type series is a female from MNHN, but male syntypes exist according to the male measurements and the drawing of male FW venation presented in Brunner von Wattenwyl (1898). Due to the lack of male characters, the comparison with other species of the genus remains limited. Molecular data obtained for the three species of the genus support the fact that they should be considered as different taxa, despite the lack of detailed information on P. punctatus gen. et comb. nov. Further information will have to be provided by future studies.

Redescription

Female

FWs reaching middle of fourth tergite, faintly overlapping. Cells of dorsal field dark brown, not translucent, with orange strong longitudinal veins and white weak transverse ones; with 9 veins on dorsal field, 4 on lateral field. Dorsal field apex truncated, lateral field posterior margin oblique.

GENITALIA. Ovipositor as long as FIII, apex not denticulate dorsally. Copulatory papilla rounded; basal sclerite forming a semi-circular ring with a small basal plate; bent at apical third in lateral view; apex narrowed and bilobed ( Fig. 8G ).
