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

Male genitalia

Pygofer lobe broad, with five macroseta at cephalo-ventral angle of lobe and one macroseta at junction area with anal tube (Fig. 2A). Pygofer dorsal appendage broad at base, tapering towards apex. Subgenital plate slightly concave near middle area, with two macrosetae on outer surface (Fig. 2B). Style with two points at apex; pre-apical lobe small (Fig. 2C). 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. 2D and G). Connective Y-shaped, two lateral arms long and central lobe large; stem well developed (Fig. 2F).

Measurement: Male length (including wing) 2.9 mm.

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

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.

Body brownish-yellow (Fig. 3A). Head brownish-black (Fig. 3A and D). Eyes black. Face brownish, anteclypeus brownish and frontoclypeus centrally dark brown with brownish lateral margins (Fig. 3C and E). Pronotum brownish two sides black (Fig. 3A and D). Scutellum black in whole (Fig. 3A and D). Forewing faint brown (Fig. 3A and C). Abdominal apodemes broad, extended to 4^th sternite (Fig. 4C).

Anufrievia unianxialis sp. nov. A Subgenital plate; B Style; C Abdominal apodemes; D Aedeagus, ventral view; E Aedeagus, style and connective; F Connective; G Aedeagus, ventrolateral view.

Male genitalia

Subgenital plate slightly concave near middle area, with three macrosetae on outer surface (Fig. 4A). Style with two points at apex; pre-apical lobe obvious (Fig. 4B). Aedeagal shaft almost straight and flat in lateral view, without any process; gonopore large, reaching 1/2 height of aedeagal shaft; dorsal apodeme small and pre-atrium well developed, as long as shaft (Fig. 4D and G). Connective M-shaped, two lateral arms long, central lobe small (Fig. 4F).

Measurement: Male length (including wing) 2.7 mm.

The new species is named from the Latin word “unianxialis”, referring to the aedeagal shaft without serrated marginal lamellae apically.

This species is similar to A. crispata Tan, Jiang & Song, 2021, but can be distinguished by the aedeagal shaft without serrated marginal lamellae; without pair of small processes curved mesally under the gonopore and the connective with distinct central lobe.
