Varicopsella odontoida Yang & Dietrich sp. nov.

(Figs 16–18, 26–34)

Description. Length ♂ 4.0mm.

Crown, pronotum and scutellum light brown, marked with dark brown lines and dots. Scutellum with basal triangles ocher (Fig. 16). Face light brown, with dark brown dots concentrated on dorsal half, eyes sliver grey (Fig. 18). Forewing light brown, with numerous small irregular dark spots (Fig. 17).

Body distinctly flattened dorsoventrally. Head including eyes wider than pronotum. Crown prominent, V-shaped in dorsal view. Pronotum long and broad, slightly declivous, striations on surface dense and oblique. Scutellum small, triangular (Fig. 16). Face flat, longer than wide, lower half strongly inflated in male. Ocelli situated about 6 times closer to adjacent eyes than to each other (Fig. 18). Hind tibia chaetotaxy PD 10, AD 8, AV 5. Forewing with 3 anteapical cells (Fig. 17).

Male genitalia. Pygofer broad, lobe bearing pair of spinelike distal processes. Subgenital plate slender, with marginal setae on dorsal region, apex with tuft of long setae ( Figs 26, 27 ). Aedeagus tubular, shaft slender with two finely serrate ventrolateral flanges near midlength, bent dorsally, gonopore apical ( Figs 28, 29 ). Dorsal connectives with upper parts falcate, with single point, ventral parts boot-shaped in posterior view ( Figs 30, 31 ). Connective small, with fingerlike protrusion in middle between dorsally bent anterior arms ( Figs 32, 33 ). Style slender, with sparse row of fine setae dorsolaterally, apex upturned ( Fig. 34 ).

Female. Unknown.

Material examined. Holotype ♂, Thailand: Phitsanulok Thung Salaeng Luang NP Dry evergreen, 16°50.217’N, 100°52.54’E, 580m, 11–18 Aug 2006, coll. Pongpitak Pranee ( QSBG).

Diagnosis. This new species resembles V. o bt us a Hamilton in the structure of the pygofer, but may be distinguished from the latter by the serrate rim of the aedeagus in lateral view and the presence of a single projection on the each upper part of the dorsal connective.

Etymology. This new species epithet refers to the serrate rim of the aedeagus in lateral view.
