Description

Male length 2.8 mm (including wing). Body yellowish. Vertex brownish-yellow, with pair of small dark brown apical spots (Fig. 3 A and C). Eyes grey. Face pale milky yellow, anteclypeus and frontoclypeus light brownish (Fig. 3 B and D). Pronotum and scutellum brownish-yellow and anterior margin of scutellum with black triangles (Fig. 3 A and C). Forewing beige (Fig. 3 A and B). Abdominal apodemes very short, not extended to 3rd sternite (Fig. 4 A).

Diagnosis

Male genitalia. Pygofer lobe broad, with dense microsetae near dorso-caudal margin and several peg-like setae on outer surface (Fig. 4 B). Pygofer dorsal appendage broadened at base, tapering towards apex (Fig. 4 C). Subgenital plate slightly concave near middle area, with three macrosetae on lateral margin, row of short stout setae along upper margin from sub-base to apex (Fig. 4 D). Style with two points at apex; pre-apical lobe small (Fig. 4 E). Aedeagal shaft straight and flat in lateral view, but long and slim in ventral view; gonopore arising from ventral surface, reaching two thirds of aedeagal shaft; dorsal apodeme well developed (Fig. 4 F and G). Connective Y-shaped, two arms slender, central lobe absent (Fig. 4 H).

Etymology

The new species is named from the Latin word " confluensus ", referring to the connective stem fused with a long process (Fig. 4 H).

Taxon discussion

This species is similar to A. akazu ( Matsumura 1932), but can be recognised by the subapical ventral surface without paired short processes and pygofer appendage not bifurcate at apex.
