Zeugodacus Hendel, 1927

Zeugodacus Hendel, 1927: 26. Raised to genus level by Virgilio et al. 2015: 177. Type species: Dacus caudatus Fabricius, 1805: 276. Type locality: Indonesia, Java.

Diagnosis.

Abdominal tergites free, scutum with medial postsutural vitta except for few species in several subgenera including Parasinodacus Drew & Romig, Paradacus Perkins and some species of Sinodacus Zia, sternite 5 of male with shallow/flat posterior emargination. In males, epandrium distinctly bulb-shaped in posterior view, proctiger hyaline, triangular (when uninflated) smaller than epandrium, lateral surstylus longer than epandrium (profile view); posterior lobe of lateral surstylus 5-6 × longer than anterior lobe. Phallus with well-developed acrophallus (single semi-tubular lobe) and patterned/granulated praeputium. Dorsal sclerite of glans without hexagonal pattern. Aculeus dorsoventrally flattened with four pairs of preapical setae ( David and Ramani 2019). Zeugodacus is similar to Bactrocera and Dacus in general appearance as they are wasp mimics and are characterised by the presence of reddish-brown to black colour with yellow vittae and markings. It can be differentiated from Dacus by the presence of free abdominal tergites and by the presence of four pairs of preapical setae; from Bactrocera by the shallow/ flat emargination sternite 5 in males, posterior lobe of lateral surstylus 5-6 × longer than anterior lobe and patterned acrophallus.
