Description

Anterior margin of head with two dark brown transverse bands on either side of a pale transverse band between ocelli, and a broad transverse brown, orange or reddish band between eyes tinged with brown anteriorly; face pale brown with variable darker brown arcs dorsally. Thorax with a transverse brown, orange or reddish band anteriorly and posteriorly on pronotum and anteriorly on scutellum. Forewings marked with brown apically and on some veins (at least in distal part of wing). Head triangularly produced, similar in width to pronotum, approximately twice as long medially than next to eye; ocelli situated on anterior margin of head close to eye. Forewing with outer subapical cell extending sub-basally towards wing margin and with a reflexed costal vein.

MALE GENITALIA. Pygofer short to long with or without a caudal process, with scattered macrosetae distally. Valve subtriangular. Subgenital plates short to long, evenly tapered to narrowly rounded apex; with several long uniseriate lateral macrosetae sub-basally to subapically and a few long fine setae at least apically. Connective Y-shaped, articulated with aedeagus; stem very short to long with or without a lightly sclerotized lobe-like area on each side. Style with well-developed preapicalal lobe and usually short acute apophysis. Aedeagal shaft short to long with a pair of usually long apical processes, gonopore apical; preatrium absent; basal apodeme usually well developed.

FEMALE GENITALIA. First valvulae with dorsal sculpture concatenate to strigate. Second valvulae abruptly expanded slightly basad of midlength and gradually tapered to apex (blade-like), with approximately 20 prominent teeth; dorsal sclerotized area and dorsal hyaline area present.

Distribution

Mainland Asia ( China, India) and in the Pacific (Sabah and Sarawak).

Remarks

This genus is similar to Selangomonus gen. nov. in appearance, but can be distinguished by aedeagus. Aedeagus of Selangomonus usually without processes (apical processes present in S. furcatus gen. et comb. nov.) and preatrium usually well developed (short in S. splinterus ).
