Gonioctena (Brachyphytodecta) mauroi species-group

Differential diagnosis. Body length 5.9–6.9 mm. Body short-oval, strongly convex ( Figs 1, 3 View Figs 1–4. 1–2 ). Dorsum reddish-brown with basal margin of pronotum black ( Figs 2, 4 View Figs 1–4. 1–2 ). Venter entirely or largely reddish-brown. Legs black, partially blackish-brown. Aedeagus long and thin, setose apicolaterally, with apical process varying in shape ( Figs 7, 9, 11–12 View Figs 6–12. 6–7 ). Gonioctena (B.) flavipennis (Jacoby, 1888) is almost identical with members of Gonioctena mauroi speciesgroup in body shape and coloration, but differs in its glabrous aedeagus. The most consistent characteristic that differentiates this species-group from other species of the subgenus Brachyphytodecta is setose aedeagus.
