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.
