Description.

Measurements. Body length: male 3.8–4.1 mm.

Ground color reddish brown. Face crimson, ocelli surrounded by dark patches (Fig. 20). Anteclypeus strongly swollen and broader in male than in female (Fig. 20).

1T apodemes not extending to end of segment III, divergent posteriorly (Fig. 35). Male pygofer in lateral view with rounded apex, bearing 5–6 rigid microsetae along posterior margin (Figs 36, 37, 69–71). Subgenital plate widest at base and terminated in rectangle; basal setae (7–8) slightly shorter than macrosetae; marginal setae (8–10) arranged in irregular 1–2 rows, discrete; macrosetae (6–7) somewhat pointed, not reaching tip of plate; feeble microsetae (6–8) weakly developed (Figs 69, 72). Aedeagus shaft tubular, with long unpaired basal process surpassing shaft apex, both shaft and process with single tiny preapical spine, gonopore apical in dorsal view (Figs 73–75). Style strongly curved medially, dentifer bearing 5-6 tiny teeth and about 4–5 setae (Fig. 76). Anal tube lamellate, tapered to acute apex (Fig. 77).

Etymology. The name is an arbitrary combination of letters.

Remarks. This species is similar to H. osificata in having the male anteclypeus strongly swollen and broadened (Figs 8, 20), but differs from the latter in having the subgenital plate macrosetae concentrated near the plate apex (Fig. 72) (concentrated near base in H. osificata (Fig. 49)). H. algulata is also similar to H. asilata in having the 1T apodemes divergent posteriorly (Figs 32, 35). However, it differs from H. asilata in having the anal tube process broad basally (Fig. 77) (anal tube process narrowed basally in H. asilata (Fig. 68)). H. algulata differs from all other known species of Homa in having a single well-developed basal aedeagal process surpassing the shaft apex (Figs 73, 74).

Distribution. Thailand and Vietnam.
