Treufalka , gen. n.

Type species: Treufalka lamellata n. sp.

Description. Head broader than pronotum. Vertex long, rounded anteriorly, in profile evenly curved to face, latter short and convex; coronal suture very short. Forewing without stalked apical cell. Hindwing with area bordered by re-emerging AA and AP veins small; CuA unbranched apically.

Abdominal apodemes moderately long, broad basally, diverging apically. Pygofer trapezoidal, strongly narrowing in caudal half, laterodorsal margin with a lobe adjacent anal tube; pygofer terminally bearing rigid microsetae on each side of lobe; ventral appendage present. Anal tube process hook-like but bowed cephalad. Subgenital plate long and narrow, far exceeding pygofer side, all categories of setae present; setae of basal group fairly long and broad and restricted to thickened outer margin subbasally, lateral macrosetae arranged in one row towards apex of plate. Paramere apophysis with prominent dentifer, few sensory pits and rather long fine setae near its base. Connective fused with base of aedeagus. Aedeagal shaft tubular, without preatrium and dorsal apodeme; gonopore dorsad near apex, small.

Remarks. Treufalka is similar to Dayus Mahmood , Ifugoa Dworakowska & Pawar , Usharia Dworakowska , Baguoidea Mahmood , Goifa Dworakowska and Dunioa Dworakowska in having posteriorly divergent abdominal apodemes and the connective fused with the base of the aedeagus but differs in its long and narrow subgenital plate. It also differs from Baguoidea , Goifa and Dayus in having the vein RP in the forewing arising from r cell rather than m cell, from Baguoidea in having a row rather than a cluster of macrosetae subapically, from Goifa by the vertex being shorter and broader than the pronotum and the dorsal margin of the pygofer side having a large lobe and all setal types present on the subgenital plate, from Usharia and Ifugoa in having the transverse veins of the forewing not situated at the same level and from Dunioa in lacking a stalked cell in the fore wing and vein MP’ arising from m cell. The new genus also differs from Goifa and Dunioa in its distinct ventral pygofer appendage.

Etymology. The generic name is an arbitrary combination of letters, and is regarded as feminine.
