Description

Body brownish-black. Head milky yellow (Fig. 1 A and D). Eyes pitch black. Face milky yellow, anteclypeus little darker than fronteclypeus (Fig. 1 C and E). Pronotum light yellow with two sides black (Fig. 1 A and D). Scutellum yellowish-brown, with dark basal triangles (Fig. 1 A and D). Forewing brownish (Fig. 1 A and C). Abdominal apodemes broad, extended to 4th sternite (Fig. 2 C).

Diagnosis

Male genitalia

Pygofer lobe broad, with five macroseta at cephalo-ventral angle of lobe and one macroseta at junction area with anal tube (Fig. 2 A). Pygofer dorsal appendage broad at base, tapering towards apex. Subgenital plate slightly concave near middle area, with two macrosetae on outer surface (Fig. 2 B). Style with two points at apex; pre-apical lobe small (Fig. 2 C). Aedeagus with shaft almost straight and flat in lateral view, pair of long processes arising from base of shaft, surpassing gonopore; gonopore reaching 3/4 height of aedeagal shaft, on ventral surface; dorsal apodeme well developed (Fig. 2 D and G). Connective Y-shaped, two lateral arms long and central lobe large; stem well developed (Fig. 2 F).

Measurement: Male length (including wing) 2.9 mm.

Etymology

The specific epithet is derived from the Latin word " ventricosus ", referring to the connective central lobe well developed.

Taxon discussion

This species is similar to A. confluensa Tan, Jiang & Song, 2021 with similar shape of style and aedeagus, but can be distinguished by the five macrosetae at cephalo-ventral angle of lobe and one macroseta at junction area with anal tube; the aedeagus with pair of long processes arising from base of shaft and the connective central lobe well developed.
