Type species— Geraldocossus durrelli Yakovlev & Sáfián, sp. nov. Gender: masculine
Description
Description. Adult (Figs 1–3). Medium sized. Antenna simple, without rami on segments. Eye hairless. Frons width equal to eye diameter. Labial palpi 1.5 Χ shorter that eye diameter. Thorax and abdomen covered with dark scales. Fore wing with rounded apex; black with faintly expressed brown pattern. Hindwing dark grey without pattern. Underside of wings dark, without pattern. Male genitalia. Uncus narrow, elongated, with a deep notch at apex. Tegumen very large, trapezoid. Gnathos branches thick, short, with strongly sclerotized dorsal surface, apices of gnathos branches strongly thickened and heavily sclerotized, with needle-like spines. Valva short, concave, spoon-like, slightly narrowed apically, heavily sclerotized including apical area, with well expressed sacculus. Juxta of very complicated shape, with three pairs of lateral processes (first pair of long stiletto-like processes diluted at right angle and directed dorsally; second pair of wide leaf-like processes, diluted in different directions; third pair of small tapered processes directed abdominally). Saccus large, cylindrical, directed abdominally. Phallus long (by ¼ longer than valve length), almost straight, vesica aperture in dorsoapical position, its length ¼ of valve length, vesica without cornuti. Female unknown.
Diagnosis
Diagnosis. The new species clearly differs from the known genera of the Politzariellinae by the following features of the male genitalia: - the needle-like spines at the apices of gnathos branches (Politzariella and Holcoceroides has the gnathos branches strongly sclerotized without specific processes, fig. 6)); - the absence of the harpe (Politzariella has the warty harpe closer to the costal margin of the valve, see fig. 6; Holcoceroides has a specific complicated construction of the valve inner surface with the development of large, strongly sclerotized hooks, see figs 7-8); - the specific structure of the juxta with three pairs of lateral processes (Politzariella has the juxta with one pair of thin lateral processes, diluted in different directions, Holcoceroides has the funnel-like juxta without lateral processes, see figs 7–8). The most significant apomorphic features of the new genus are: the needle-like processes at the apices of gnathos branches and the specific juxta with three pairs of lateral processes.
