Burmascopus longidens sp. nov.

(Figs. 2, 10)

Description. Length (including wings): male 5.3 mm, female 5.5 mm.

Crown yellowish brown (Fig. 2 A). Frontoclypeus, anteclypeus and lora brownish (Fig. 2 D). Gena brown with dark brown grooves. Ocelli dark brown. Pronotum and scutellum brown. Mesonotum with basal triangles only slightly darker than rest of sclerite (Fig. 2 C). Forewing brown with veins slightly paler.

Face including eyes slightly wider than long; lateral frontal sutures reaching ocelli; frontoclypeus broad; lateral margin of anteclypeus concave; lora broad (Fig. 2 D). Mesonotum and scutellum longer than pronotum and crown together.

Pygofer elongate, dorsum with broad membranous area. Segment X fused to pygofer with internal process forked apically; inner ventral process curved dorsad subapically, nearly reaching caudal margin, apex fork-shaped (Fig. 10 A). Subgenital plate shorter than pygofer, with fine and long setae on dorsal margin in distal 2/3 and near base of ventral margin (Fig. 10 A). Connective with medial longitudinal dorsal keel. Style curved dorsally, dorsal margin with tubercle near apical third, apex evenly tapered, with distinct apical and preapical groups of dense fine setae on dorsal margin (Fig. 10 F). Aedeagal shaft slender and evenly curved dorsad, crenulate along lateral margin; apex tapered to blunt tip in lateral view, narrowly rounded in ventral view; dorsal apodeme somewhat expanded dorsad and rounded in ventral view; preatrium longer than shaft, with membranous area on ventral margin; gonopore subapically on ventral surface (Figs. 10 D–E).

Material examined. Holotype, ♂, Malaysia, Sandakan, coll. Baker (USNM) . Paratypes, 1♂ 1 ♀, same data as holotype (USNM) .

Etymology. The specific epithet refers to the longer crenulate on lateral margin of the aedeagal shaft.

Remarks. This species can differs from the type species in lacking dark markings on the pronotum and scutellum and face, and in the crenulate lateral margin of the aedeagal shaft.
