Agnesiella Dworakowska 1970

Agnesiella Dworakowska, 1970 Agnesiella Dworakowska, 1970: 211 Type species: Typhlocyba aino Matsumura, 1932, by original designation. Description. Body with ground color ivory to brownish. Vertex and face junction usually with 2 sesame-like whitish patches; vertex usually with a pair of roundish black patches near eye inner margins. Pronotum usually with an oval dark longitudinal patch near center of anterior margin and 1 or 2 pairs of dark patches laterally. Forewing basal 2/3 generally with brownish patches, patches at distal end of ScP+RA and MP''+CuA' veins, and 3rd apical cell usually brownish; brochosome area semi-transparent to reddish-brown with patches at both ends brownish to black. Crown obtusely protruding medially, narrower than pronotum with length about 1/2 that of pronotum, and with anterior and posterior margins approximately parallel. Pronotum with anterior margin arched and posterior margin straight. Apical half of forewing narrowing gradually, with RP and MP' veins confluent at the base and 3rd apical cell subtriangular. Hind wing transparent with R and MP veins confluent terminally. Abdominal 2S apodemes developed and usually reaching 5th or 6th abdominal sternite. Male pygofer generally with 2 setal groups, posterior margin generally with digitiform process extended dorsad or backwards and a small protrusion bearing small rigid setae on upper part. Length of genital valve approximately 1/5 to 1/4 length of subgenital plate. Subgenital plate club-shaped, usually with slightly expanded distal end, outer margin usually narrowed subapically with a protrusion generally bearing few peg-like setae; apical half usually with small rigid setae and fine setae. Style usually with subapical processes varying in length, number and angle; caudal half with row of microsetae on outer side and row of sensilla pores on inner side. Connective Y-shaped with stem well developed. Aedeagal shaft slender, usually with tooth-like end curling inwards and lamellar or digitiform ventral processes; gonopore apical. This genus resembles Linnavuoriana Dlabola, 1958 in having paired spots on the head and pronotum and lacking macrosetae on the subgenital plate, but differs in having a pair of black submarginal spots on the vertex and one or more spinelike processes on the male pygofer.
