Description

Measurements. Body length: male: 3.8–4.1 mm.

Ground color red. Anteclypeus tapered and weakly convex, not expanded.

1T apodemes reaching to middle of segment III, divergent posteriorly (Fig. 32). Male pygofer with dorsal margin slightly protruded in profile apically, bearing 5–6 rigid microsetae along posterior margin (Figs 33, 34, 62, 63). Subgenital plate far exceeding pygofer lobe, strongly narrowed apicad; basal setae (7–8) fully truncated and restricted to end of caudal protrusion in basal 1/3; marginal setae (3–4) strictly distributed apicad; macrosetae (4) inconsistent, basal one distinctly shorter than others; feeble microsetae (4–5) sparse, indistinct (Figs 33, 62, 64). Aedeagus shaft tubular, relatively short and tapered distally, with pair of long, slender, symmetrical processes arising near base, bowed laterad then curved posteromesad and surpassing shaft apex; gonopore apical in dorsal view (Figs 65, 66). Style S-shape in outline, dentifer bearing 5–6 teeth and about 4–5 setae on lateral surface near apex (Fig. 67). Anal tube process evenly curved and attenuate (Fig. 68).

Etymology. The name is an arbitrary combination of letters.

Remarks. This new species is similar to H. sinensis in having the subgenital plate strongly narrowed in the distal 2/3 and folded in the section with basal setae (Fig. 64). However, H. asilata differs from H. sinensis in having the 1T apodemes strongly divergent (Fig. 32) (1T apodemes almost parallel in H. sinensis (Fig. 83)). It also differs from H. sinensis in having the aedeagus shaft with a pair of symmetrical ventrobasal processes (Figs 65, 66) (aedeagus shaft with asymmetrical distal processes in H. sinensis). This species appears to be the least common species of the genus occurring in Thailand. Out of the> 100 male specimens from Thailand dissected, only three belong to this species.

Distribution. Thailand.
