INTRODUCTION
Cossidae (Lepidoptera) of Neotropical region are very poorly studied.For the majority of taxa described from Neotropics, the genitalia structure remains unknown, the size of genera is still unclear, the name-bearing types are not examined.Some progress in the study of the Neotropical Cossidae was made in the recent years.The Cossulinae of Costa Rica were thoroughly revised (Davis et al., 2008), the taxonomic position of the genus Miacora Dyar, 1905 was resolved (Yakovlev, 2014), the faunal list of Cossidae of Argentine was published (Penco & Yakovlev, 2015).In this article we give a redescription of the genus Psychonoctua Grote, 1865.This genus was assigned to P. personalis Grote, 1865 from Cuba (Grote, 1865).Later a series of species from Central America and the Caribbean region was described (Schaus, 1901(Schaus, , 1911;;Hampson, 1904;Barnes & McDunnough, 1910;Dyar, 1914Dyar, , 1918Dyar, , 1925Dyar, , 1940;;Lindsey, 1926), these species are now assigned to the genus Psychonoctua (Schoorl, 1990: 127).Schoorl (1990) also provides data on three non-described species from Panama, the Antilles and the Virgin Islands, the specimens of which are deposited in the collections of the Nationaal Natuurhistorisch Museum (Leiden, The Netherlands) and Zoologisk Museum (Kobenhavn, Denmark).The name-bearing types of the majority of the described taxa are photographed, but there was no morphological examination.Basing on the collection of the Museum Witt (München) (further -MWM) we have examined the specimens of two species: type species of the genus − P. personalis Grote, 1865 and P. jamaicensis (Schaus, 1901).
Description.Male.Length of fore wing 12-16 mm.Antenna bipectinate from base to middle, distal half filiform.Fore wing elongated, apex tapered, coloring pale grey with thin reticulated pattern, pale portion in cubital area and black discal spot.Several black strokes on costal edge of fore wing, thin pale border on outer edge of wing, fringe mottled, dark at veins and pale between veins.Hind wing pale, without pattern, with minor spraying of black scales at anal angle, fringe pale with bunches of dark scales near anal edge.
Male genitalia.Uncus with thick base, distal part strongly elongated, thin, with parallel edges and tapered apex; gnathos arms thin, ribbon-like, slightly narrowing from base to apex, not fused; valve narrow, edges practically parallel, apex rounded, notch at abdominal edge near base; juxta of medium size with long wide leaflike lateral processes; saccus semicircular, small; phallus thick, short (¼ shorter than valve), vesica very big, with long ribbon-like sclerites in its lateral surfaces, one of them 3 times larger than other.
Description.Male.Length of fore wing 18 mm.Antenna bipectinate from base to middle, distal half filiform.Fore wing elongated, grey with continuous thin reticulated pattern, relatively big black V-shaped spot near base of discal cell, brown brushstroke on costal edge (on border between two proximal thirds and distal third of wing length), brown portion at wing base (continuous at costal edge and split into brown strokes in cubital area), fringe grey.Hind wing grey without pattern, fringe grey.
Male genitalia are very similar to those of P. personalis.The differences are: uncus with narrowing edges, saccus larger, notch at abdominal edge of valve more expressed.
Female larger.Length of fore wing 20 mm.Antenna filiform.Fore wing grey with relatively rare sputtering of black scales, discal black spot small, expressed more poorly than that of male.Hind wing grey without pattern.
Female genitalia.Ovipositor very long.Papillae anales tapered, anterior and posterior apophyses very long, equal in length, antrum slightly dipped, funnel-shaped, ductus wide, short, bursa pouch-like with large signum on lateral surface, channel (ending with small rounded bulla) extending from lateral surface of bursa.

DISCUSSION
The morphological study conducted for the first time has proved the assignation of the genus Psychonoctua to the Zeuzerinae subfamily.The external characters (elongated fore wings, thin reticulated patters), the antennae structure (bipectinate from the base to middle, with a filiform distal half) and the genitalia structure of males (reduction of the gnathos, the long poorly sclerotized lateral processes of the juxta, complicated structure of the phallus) and of females (presence of bulla), are typical for the representatives of this subfamily.The peculiar apomorphic characters of Psychonoctua are narrow valves and an expressed notch on the abdominal edge of the valve.
