description: Kozloviella viazmenskyi sp. n.
(Figs 1a, 1b, 9a, 10a, 11a, 13a, 15a, 16a, 17a, 17b)
Diagnosis. Similar in general color and FW texture to many species of the cibyrine clade (sensu Grehan 2012), but contrasting with narrower forewings and slightly concave costal margin, and particularly a narrow and oblique, black V-shaped line that appears to be unique to this species. The yellowish orange color of this species contrasts with the grayish brown of Dugdaleiella gen. n. and the yellowish brown to grayish brown color tones of Pfitzneriella species.
Description. Male (Figs 1a, 1b): Wingspan: 34 mm; FW length: 17 mm, width: 7 mm, ratio 2.4: 1; HW length: 14 mm, width: 11 mm, ratio 1.3: 1.
Head. Scales covered with dark brown tipped yellowish brown piliform scales, as also are the frons and vertex. Interocular-antennal antennal scales piliform, extending over the eye. Antenna filiform with 39 flagellomeres, annuli slightly compressed, laterally covered with numerous sensillae chaetica, the basal 3-4 annuli covered with some lamellar scales; scape barrel shaped, covered with lamellar scales. Labial palpi long (longer than surrounding scales); distal palpomere digitiform, 2.3 times length of basal segment, subapical sensory pit present (Fig. 9a).
Thorax. Dorsal scales greyish brown, ventral yellowish brown with darker brown at apex of scale. Legs (Fig. 13a) coloured as the thorax: pro-, meso-, meta- legs length ratio 1.3:1.5:1; epiphysis present; tibial and tarsal scales long, but not obscuring tarsomeres, dorsal scales of tarsi 1–4 about 1/3 longer than tarsomeres, ventral tarsal scales short; metaleg pale orange-brown, femoral and tibial scales piliform. Wings narrow, slightly wider distally. FW distinctly narrow compared to HW, mid-costal margin concave, outer margin convex, curving gradually to anal margin; venation hepialine (Dumbleton 1966), base of FW anal vein strongly curved anteriorly, distally curved posteriorly (Fig. 10a); dorsal ground colour pale yellowish orange with areas of darker orange-brown and dark brown shading and scattered black markings; oblique black line forming a V-shape with outer line extending between Cu and apex (Fig. 11a); orange-brown shading predominant over outer discal cells and near apex. HW greyish brown with pale reddish brown towards outer margin.
Abdomen. Greyish brown, narrow, distally wider around genitalic region. Tergum VIII rectangular, wider than long, sternum VII wider than long (Fig. 16a).
Male genitalia. See description of the genus. Ventral surface of saccus forming two subrectangular lobes, separated medially. Phallus membranous without cornutus.
Female unknown.
Distribution. Northern Peru, known from the type locality only (Figs 27a, 29). Collected in a mountain valley in the eastern Andes adjacent to disturbed forest with local clearing and farming activities at 2,050 m (Figs 26a, 26b).
Ethology. Attracted to UV-light at collecting sheet.
Host plant. Larval habits and host plants are unknown.
Etymology. This species is named after Alexander Lvovich Viazmensky (Saint Petersburg, Russia), the famous Russian aquarellist and the passionate fan of mushrooms, at the special request of Anton Kozlov (Moscow, Russia).
