Abstract: Tribe Gereniini Brunner von Wattenwyl, 1893 Remarks. This tribe consists of 24 species in six genera distributed in South-East Asia and India, namely Gerenia Stål, 1878, Anacranae Miller, 1934, Striatosedulia Ingrisch, 1989, Bibractella Storozhenko, 2002, Leosedulia Storozhenko, 2009, and Anasedulia Dawwueng, Storozhenko et Asanok, 2015 (Stål, 1878; Miller, 1934, Ingrisch, 1989; Storozhenko, 2002, 2009; Dawwueng et al., 2015; Tan et al., 2016, 2017; Cigliano et al., 2025). Members of this tribe are characterized by follow combination of features: Male medium-sized for subfamily; female larger and more robust. Head considerably shorter than pronotum. Frontal ridge almost parallel-sided and distinctly narrower than width of vertex between eyes. Eyes large, oval; vertical diameter of eye 2–2.2 times in male and 1.5–1.7 times in female as long as subocular furrow. Foveolae absent. Antennae filiform, 20–25-segmented. Pronotum long, crossed by three transverse furrows; prozona considerably longer than metazona; lateral carinae usually absent (well defined in Bibractella); median carina distinct but low (or vestigial in Anacranae). Prosternal spine straight, conical, with obtuse apex. Mesosternal lophi broad, widely separated. Tegmina abbreviated, touching each other in rest position, or lateral, scale-like; rare, in males of Gerenia dorsale (Walker, 1870), G. intermedia Brunner von Wattenwyl, 1893 and G. selangorensis Miller, 1935 from India, Myanmar and Malaysia respectively, tegmina and hind wings far surpassing apex of hind femora. Hind wings usually abbreviated or absent. Hind femora stout with upper keel serrated; lower lophi of hind knees with broadly rounded apex. Hind tibiae with 6–9 outer dorsal spines and 8–11 inner dorsal spines; outer apical dorsal spine absent. Hind tarsi short, not longer than half of hind tibiae; third segment distinctly shorter than two others together; arolium large, almost reaching apex of claws. Tympanum large, oval. Furculae on posterior margin of the male tenth tergite present or rare vestigial. Male cerci conical (in Gerenia and Anacranae) or elongated, compressed and gently incurved, in apical third suddenly narrowed (other genera). Female cerci conical with obtuse or pointed apex. Ovipositor short or rare elongated. Male genitalia: epiphallus bridge-like, ancorae present; lophi of epipallus triangle or broadly rounded; the apical valves of penis and cingular valves long; basal valves of penis connected with apical ones by flexure.
