Type material examined: Lectotype (here designated) of Gyrophaena (Acanthophaena) rufiventris Cameron 1920 , 1 ♀ [dissected; original labels as in Fig. 99 ]: ‘ Ceylon. G. Lewis. 1910–320.’, ‘Kitulgalle. 1,700 ft. 17–20.I.82.’, ‘SYN- TYPE’, ‘ Phanerota (Acanthophaena) rufiventris (Cameron) Enushchenko I.V. 2019 det.’ ( BMNH).

Paralectotype: 1 ♀: same labels as the lectotype ( BMNH) .

Distribution. Sri Lanka.

Remarks. The species was originally described from “Galle, Kitulgalle, Dikoya” based on the unspecified number of syntypes. Later, the same author ( Cameron 1939) redescribed it as G. (A.) rufiventris .

Habitus as in Fig. 95 . Body length: 2.00– 2.50 mm.

Male unknown.

Female. Apical margin of abdominal tergite VIII about as that in Ph. (A.) appendiculata ( Fig. 97 ). Apical margin of abdominal sternite VIII widely rounded ( Fig. 98 ). Spermatheca as in Fig. 96 .

The species is distinguished from G. (A.) appendiculata by the coloration of antennae (antennomeres 1–4 and apical part of apical antennomere yellow, antennomeres 5–11 brown while all antennomeres in Ph. (A.) appendiculata are yellow) and abdomen (all tergites yellow to reddish-yellow, while in Ph. (A.) appendiculata tergites V–VI are distinctly darker than other tergites), and the shape of the spermatheca (see above).
