Paratypes: 1 ♂, 1 ♀♀, [Indonesia], G. Paloe, Tampoe, West Celebes [Sulawesi], 2.700’, Jan. 1937, (J.P.A. Kalis), specimen photo numbers: 012832479 (♂), 012832517 (♀), slide number: 010315510 (♂).   
DESCRIPTION. Length of male fore wing 18–20 mm. Antenna bipectinate from base to half of length, distally not pectinate.

Fore wing elongated, apically sharp, light-creamy, wide greyish-bluish portion medially, reticulated brown pattern along all wing edges. Hind wing significantly shorter than fore wing, light-creamy, sprayed with greyish scales, reticulated brown pattern along outer edge and in anal angle area.

 How to cite this article: Yakovlev R. V. 2020. New species of genus Tarsozeuzera Schoorl, 1990 (Lepidoptera: relatively short; gnathos arms very thin, ribbon-like; gnathos reduced; juxta trapezoidal with small leaf-like lateral processes; saccus semicircular, small.Phallus robust, short (slightly shorter than valve), slightly curved in basal third, longitudinal folds in distal third, large finger-like cornutus in dorsal part of vesica.   
Female. Length of fore wing 33 mm. Antenna simple, not pectinate. Fore wing long, apically rounded. Wing pattern identical to that of male.  
 DIAGNOSIS. Among all species of the genus, externally may be confused with T. fuscipars and T. kochi. Differs from the closest species in the following characters:   
 — T. fuscipars and T. kochi are slightly smaller (length of the male fore wing is 15–19 mm);   
 — T. fuscipars and T. kochi have more expressed brown pattern on the fore wing (especially along the rear edge of the wing);   
 — the valve in T. fuscipars and T. kochi is significantly narrower basally (in T. prashkevitchi sp. nov. the valve is wide, with even edges).   
ETYMOLOGY. The new species is named after the wellknown talented Russian writer, Gennady Prashkevich (Novosibirsk).
