Length: ♂ 3.2 mm–3.4 mm.
Ground colour of body yellowish (
Fig. 118
). Crown with light green patch on each side of coronal suture (
Fig. 116
). Eyes brown. Pronotum with irregular patches on anterior margin of pronotum and under eyes. Forewing and hind wing semitransparent. Abdomen light yellow. Legs light green to yellow-greenish (
Fig. 117
).
Ventral abdominal apodemes well developed, reaching midlength of segment 5, parallel-sided to broadly rounded apices (
Fig. 58
). Male pygofer slightly narrowing caudad, with a few rigid setae on caudal-dorsal angle (
Fig. 51
); ventral pygofer appendage tapering, slightly curved, not exceeding lobe margin (
Fig. 52
). Anal appendage solid, with numerous serrations apically (
Fig. 53
). Subgenital plate in lateral view, curved gradually caudodorsad apically, tapering to rounded apex; with numerous macrosetae and fine setae somewhat irregularly scattered; dorsolateral margin group A with 5 long stout setae, group B with 24–26 short microsetae on apical 2/3 (
Fig. 60
), group C double near base, with a single row of macrosetae distally, group D irregular with numerous elongate setae. Paramere with 6–7 teeth on dentifer, several setae subapically (
Fig. 59
). Connective broad, with anterior margin slightly emarginated medially (
Fig. 54
). Aedeagus with preatrium straight, longer than shaft; dorsal apodeme well developed; shaft in lateral view curved dorsad, with ventral notch adjacent to gonopore, without dorsal denticuli; apical process elongate, slender, strongly curved, apex tapered and serrate (
Figs 55, 56
).
Etymology.
The specific epithet is derived from the Latin "
reflexus
" meaning "turned back" and refers to the reflexed aedeagal process.
Diagnosis.
The new species is similar to
A. kaicola
Dworakowska, 1982
, but can be distinguished by the strongly curved aedeagal appendage lacking an apical bifurcation.
