Description.

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

Ground color red. Anteclypeus slightly broader in male than in female (Fig. 8).

1T apodemes forming arc bending apicad, not extended to segment II (Fig. 26). Male pygofer in profile with apex rounded, bearing 6–7 rigid microsetae along posterior margin, dorsal bridge well developed (Figs 27, 28, 46–48). Subgenital plate far exceeding pygofer lobe, gradually curved toward pygofer ventral margin; basal setae (7–8) situated on broadest section of plate, two or three setae separated from bristle clusters; marginal setae (6–8) sparse, arranged in single row; macrosetae (5) discrete, not extended to tip of plate; feeble microsetae (10–12) inconspicuous (Figs 27, 46, 49). Aedeagus shaft tubular, with attenuate distal extension and pair of shorter asymmetrical processes subapically, one rounded and longer, other shorter and pointed; gonopore subapical on ventral side (Figs 50, 51). Style bearing 6–7 tiny teeth apically and 5–6 fine setae subapically (Fig. 52). Anal tube process smooth (Fig. 53).

Etymology. The name is an arbitrary combination of letters.

Remarks. This new species is similar to H. haematoptilus in having the 1T apodemes not extended to segment II and triangular in shape (Fig. 26). However, H. osificata differs from H. haematoptilus in having the aedeagus with three distal projections, all extended distad (Fig. 50). The aedeagus H. haematoptilus has only two distal projections, one extended ventrad (Fig. 42).
