Luodianasca gen. n.

Type species: Luodianasca recurvata n. sp.

Description. Body robust. Head with eyes narrower than maximum width of pronotum. Vertex slightly produced medially, rounded anteriorly with transition to face rounded in profile; coronal suture distinct, extending to anterior margin of vertex. Face narrow and slightly convex in profile. Forewing with 3rd apical cell sometimes with short stalk. Hindwing with CuA bifurcated.

Abdominal apodemes weakly developed. Male pygofer short, terminally with few rigid microsetae on each side of lobe; ventral appendage absent. Anal tube large, process broad at base, subapically abruptly narrowing and turned anteriad. Subgenital plate broad basally, narrowing apicad, with large basolateral protrusion, setae of basal group unrecognizable, fine setae arising at extreme base of outer margin and macrosetae arranged in single row terminating subapically. Paramere serrate apically, preceded by setae and sensory pits. Connective lamellate with small caudal lobes. Aedeagal shaft tubular, preatrium long; without dorsal apodeme.

Etymology. The name is derived from the type locality of the type species (Luodian, Guizhou Province). Gender: feminine.

Remarks. Luodianasca is similar to Alebroides Matsumura , Ghauriana Thapa , Matsumurama Thapa , Nikkotettix Matsumura and Bhatasca Dworakowska in that the veins MP’ and RP in the forewing arise from m cell and CuA in the hindwing is branched apically. It is also similar to Ghauriana , Bhatasca and Matsumurama in having uniseriate lateral macrosetae of the subgenital plate, and also to Bhatasca in lacking the ventral pygofer appendage. The new genus differs from these genera in having the subgenital plate broad basally, the basal group setae not identifiable, anal tube appendage strongly developed, abdominal apodemes weakly developed and the coronal suture reaching the anterior margin of the vertex.
