Pronotum smooth medially; two pairs of posteroangular setae usually developed (cf. Fig. 1 ) (no long setae in T. veversae Mound & Masumoto from Australia ). Mesonotum with median pair of setae situated near posterior margin or ahead of submedian setae (cf. Figs. 3 , 7 ). Metascutum usually smooth, often weakly sculptured medially; median pair of setae situated at or near anterior margin; campaniform sensilla present or absent. Prosternal ferna undivided. Mesosternum without sternopleural suture; endofurca with spinula. Metasternal endofurca usually without spinula. Metaepimeron with 0 to 2 setae. Fore wing first vein with median long gap in setal row and two setae distally; clavus usually with four (rarely three or five) veinal and one discal setae; posterior fringe hairs wavy. Tarsi 2­segmented. Abdominal terga without ctenidia or posteromarginal craspeda; terga II to VII with three setae (B3–B5 setae) along lateral margin arranged in straight line, usually smooth medially and sculptured laterally (cf. Fig. 4 ); tergum VIII without posteromarginal comb; tergum IX with or without campaniform sensilla (cf. Fig. 10 ); tergum X without median split; sterna without posteromarginal craspeda, with or without discal setae; sternum II with two or three pairs of posteromarginal setae; sterna III to VII with three pairs of posteromarginal setae; laterotergites without discal setae. Ovipositor developed. Male . Macropterous or apterous. General structure and colour similar to female. Abdominal tergum IX usually with a pair of posteromarginal processes (drepanae) (cf. Fig. 11 ); sterna III to VIII with numerous scattered, or three to six, glandular areas (cf. Fig. 13 ).
