Typhlocyba aino Matsumura, 1932 Type-locality. Japan . Distribution: Palaearctic and Oriental regions. Body with ground color ivory to brownish. Joint area of vertex and face usually with 2 sesame seed-like whitish patches near medial border of eyes; vertex usually with a pair of roundish black patches also near medial border of eyes. Pronotum usually with an oval dark patch longitudinally near center of anterior margin and 1 or 2 pairs of dark patches laterally. Forewing with most of patches brownish to ochre usually on basal half, patches at both ends of brochosome field brownish to black; patches at distal end of ScP+RA and MP"+CuA' vein, and 3rd apical cell usually brownish. Crown obtusely protruding medially and narrower than pronotum with length 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' vein confluent basally and 3rd apical cell subtriangular. Hind wing with R and MP vein confluent terminally. Abdominal 2S apodemes developed and usually reaching 5th or 6th abdominal sternite. Male pygofer side generally with 2 setae areas, posterior margin generally with digitiform appendages extended dorsad or backwards and a small protrusion bearing rigid microsetae on upper part. Length of genital valve approximately 1/4 or 1/5 length of subgenital plate. Subgenital plate club-shaped usually with slightly expanded end, outer margin usually narrowed subapically with peg-like setae or a small protrusion arising from bent part; some rigid microsetae and fine moderate setae on apical half. Paramere with subapical protrusions varying in length, number and angle; caudal half with row of microsetae on outer side and row of sensilla pores on inner side. Connective Yshaped with stem relatively developed. Aedeagal shaft slender with tooth-like end curling inwards and lamellar or digitiform ventral appendages; gonopore apical. This genus resembles Linnavuoriana Dlabola 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.
