Notes on Typhonoya Prozorov

Imago. Head. Antennae bipectinate, pectination gradually shortening in length until tip ( Fig. 2 ). Eyes loosely short haired. Labial palps three segmented, third segment about half as long as second segment ( Figs 1, 3 ). Maxillary palps thin, elongated ( T. kravchenkoi maxillary palps significantly longer than of T. longipennis , Fig. 1 ). Legs. The tibial spur formula is 0-2-2 ( Figs 4–5 ). Epiphysis claw-shaped, almost three fourth of tibia in length. Distitarsus bears apical pair of long chaetae ( Fig. 6 ). Venation. Both species almost similar in vein scheme, overall the venation is typical of Gastropachini ( Figs 7–10 ). Hind wing additional cell size almost of R-Cu cell; two to four humeral veins; CuP absent. Resting pose. Resembles other Gastropachini ( Figs 11–13 ). Labial palps forward directed, stretched. Antennae backward directed, placed laterally along thorax. Thoracic spackle pattern clearly visible ( Fig. 13b ). Forewings form a pointed “tent” above abdomen, tornal scales turned upward, like a fan ( Fig. 13a ). Hindwings moved out laterally until about Rs. Long abdominal scales protrude from hind wings.
