Serridiocerus membranaceus sp. nov.

( Figs. 8 , 16 )

Description. Length (including wings): male 5.5–5.8 mm.

Body brown. Crown-face transition with round black spot on either side of midline closer to eyes than ocelli. Face brown; gena brownish with black markings. Pronotum brownish with indistinct brown markings. Mesonotum with basal triangles brownish and small, disc with two black spots, and two black stripes on lateral margin. Forewing transparent, veins mostly darker but with white on apex of claval veins.

Male pygofer broadened medially, dorsum and medial and ventral margin with membranous area. Subgenital slightly shorter than pygofer, with few short setae. Aedeagal shaft somewhat foot-shaped in lateral view, with heellike ventral projection and slightly curved and tapered distal part; atrium in ventral view with each side expanded and trilobed; gonopore near midlength of distal portion of shaft. Style with elongate tapered distal section extended lateral beyond acutely rounded medial heel.

Material examined. Holotype, ♂, Malaysia, Sandakan , coll. Baker ( USNM) ; Paratypes, 2♂♂, same data as holotype ( USNM) .

Etymology. The specific epithet refers to the pygofer with a membranous area on the dorsum and medial and ventral margins.

Remarks. This species can easily be recognized by the well developed ventral apodeme and serrate lateral margin of the aedeagus.
