Blaiseus malayensis Douglas , new species

( Figs. 1 , 12 , 23 )

Material examined. Two males.

96 Holotype: Male labeled: ‘‘Doherty’’; [handwritten] ‘‘Perak’’; ‘‘Fry Coll./ 1905.100.’’; [red] ‘‘ HOLOTYPE / Blaiseus / malayensis/ Douglas 2006,’’ with genitalia in microvial attached to pin ( NHM). Paratype : 1 male labeled: ‘‘Doherty’’; [handwritten] ‘‘Perak’’; ‘‘Fry Coll./ 1905.100.’’; [yellow] ‘‘PARA- TYPE/ Blaiseus / malayensis/ Douglas 2006’’ ( NHM) .

Type locality: Malaysia, Perak State.

Diagnosis. Legs: Femora and tibiae not fossorial; protibiae without teeth.

Description. Male: Length 4.5 mm. Integument red-brown, with elytra lighter coloured ( Fig. 12 ). Head: Antennae reaching to hind coxae; labrum concave in side view; nasale with a pair of circular pits antero-mesad of antennal fossae.

Prothorax: Hypomeron with hind edge sinuate immediately meso-ventrad of hind angles ( Fig. 1 ). Prosternum with ventral surface of prosternal process with carinae surrounding dorsal surface weak or absent. Pterothorax: Scutellum with posterior apex pointed (Fig. 3). Elytra not upturned at apex; suture and interval 5 costate on apical quarter; epipleurae with globular serrations. Hind wings with CuA1 not forked at junction with MP3+4. Legs: Femora and tibiae not expanded; protibiae without teeth; tarsomere 4 lobed. Male genitalia: Aedeagus with median lobe broadest near apex, weakly concave mesally at apex; parameres with ventral apices much longer than dorsal apices ( Fig. 23 ); inner apices present but unsclerotized. Female: Unknown.

Comments. This is the only known Blaiseus without apparent adaptations for fossorial living. Additional evidence for the non-conspecificity of this and all others include its small size and distinctive aedeagus. This is the only Blaiseus species known from Malaysia.
