Genus Anaselina Storozhenko , gen. nov.

Type species Vingselina minor Sjöstedt, 1921 .

Description. Body small-sized for Australian Batrachideinae . Antennae filiform. Antennal grooves situated between lower margins of eyes ( Figs 9, 12, 14 ). Compound eyes not elevated above pronotum in lateral view. Frontal ridge, in lateral view, broadly rounded with shallow concavity above lateral ocelli ( Figs. 9, 12 ); in frontal view, this ridge broad; lateral carinae of frontal ridge moderately diverging downwards and gentle incurved below antennal grooves ( Fig. 14 ). Pronotum short; anterior margin of pronotum, in dorsal view, broadly triangular and almost reaching middle of eyes; apex of posterior process of pronotum excised ( Figs. 10, 13 ). Median carina of pronotum low, in profile almost straight ( Figs. 9, 12 ), in cross-section triangular. Hind margin of lateral lobes of pronotum with shallow lower sinus; tegminal sinus absent; lower edge of infrascapular area barely sinuate ( Figs. 9, 12 ); lower part of lateral lobe of pronotum, in dorsal view, forming rounded lobule ( Figs. 10, 13 ). Tegmina and hind wings absent. Fore and mid femora with lower carinae weakly sinuate; dorsal side of fore femora sulcate. Upper carina of hind femora gentle serrated, without lappets. First tarsal segment of hind legs distinctly longer than third segment. Female subgenital plate with deep median furrow bordered with ridges ( Fig. 11 ). Valves of ovipositor narrow, dentate.

Differential diagnosis. The new genus differs from the Oriental genera of Batrachideinae in the same characters as Vingselina and easy recognizable from Australian taxa in the low and almost straight median carina of the pronotum. Anaselia gen. nov. is also similar to the genus Epitettix Hancock, 1907 (subfamily Cladonotinae ) especially in the low median carina of the pronotum and the shape of frontal ridge. All species of Epitettix are characterized by keeled dorsal side of the fore and mid femora and by smooth female subgenital plate ( Hancock, 1907; Tumbrinck, 2014; Storozhenko & Dawwrueng, 2014; Zheng & Liu, 2016), while in Anaselia gen. nov., the dorsal side of the fore and mid femora sulcate, and the female subgenital plate with deep median furrow.

Composition. The genus is monotypic.

Etymology. This name is originated from Latinized Greek prefix “ana-” and the genus name Vingselina . Gender feminine.
