Genus Anacranae Miller, 1934

Anacranae Miller, 1934: 537 ; Willemse, 1957: 353; Otte, 1995: 269; Yin et al., 1996: 53; Storozhenko, 2002: 602.

Type species: Anacranae nuda Miller, 1934 , by original designation.

Differential diagnosis. Anacranae belongs to the group of Gereniini genera with scale-like tegmina which not touching each other in rest position; therefore, it easy recognizable from the genus Gerenia which characterized by tegmina touching each other in rest position and almost reaching or surpassing apex of abdomen. In the genus Bibractella median and lateral carinae of the pronotum are well defined and tegmina are very short, reaching hind margin of mesonotum only (in Anacranae median and lateral carinae of the pronotum absent and tegmina reaching the apex of 2 nd abdominal tergite). In the genera Sedulia and Leosedulia median carina of the pronotum distinct; tegmina with large and shining black spot in central part of tegmen; ovipositor short, ventral valves with large tooth near base (in Anacranae median carina of the pronotum absent, tegmina scale-like without shiny black spot, and ovipositor with elongated valves, lower side of ventral valves smooth). The genus Striatosedulia differs from Anacranae by well defined median carina of the pronotum, by a row of parallel veinlets in costal field of tegmen, and by male subgenital plate terminating in two obtuse lateral lobes (in Anacranae costal field without veinlets and male subgenital plate with obtuse apex). Anasedulia is easy recognizable from Anacranae by follow combination of characters: posterior margin of pronotum angularly rounded; median carina of pronotum distinct; tegmina with shining black spot and the costal field of tegmen broad with irregular veinlets; male subgenital plate with a pair of unusually long lateral lophi covered by long hair-like setae; ovipositor short, hook-like (in Anacranae posterior margin of pronotum broadly rounded or almost straight, tegmina without shining spot, costal field narrow, male subgenital plate conical without lateral lobes, and ovipositor with elongated valves). Moreover, the males of Anacranae differ from all representatives of Gereniini in enlarged paraprocts with distinct process of different shape on its lateral side, while in other genera paraprocts not modified.

Composition. Genus consists of four species from Thailand and Vietnam ( Cigliano et al., 2025). One new species is described in this work.
