Popis: Nemophora agassizi Kozlov, sp. nov. (Figs. 3, 13) Holotype ♀: Papua New Guinea, New Guinea, Enga, Wabag (5o28'S 143o40'E); labelled: 8 mm circle with red margin, print ���Holo- | type���; 8 �� 13 mm, print ��� Papua New Guinea | Enga Prov., Wabag, | Kaiap, 9000 ft. | 10.xi.1984 | D. J. L. Agassiz���; 4 �� 13 mm, print ��� D. J. L. Agassiz | B. M. 1985-13���; 8 �� 18 mm, print ��� HOLOTYPE ♀ | Nemophora | agassiz i Kozlov��� (NHM). Diagnosis. Similar to N. kalshoveni and N. humerella, from which it differs by monotonous silver grey basal quarter of forewing (basal half of forewing in N. kalshoveni and N. humerella is scattered with both dark brown and white or yellow scales). From N. toxopeusi differs by monotonously brown labial palpus (apical segment of labial palpus in N. toxopeusi is white), as well as by yellow oblique stripe in the apical part of forewing (white in N. toxopeusi) not reaching 0.5 �� forewing width (reaching at least 0.7 �� forewing width in N. toxopeusi). Etymology. Named after David John Lawrence Agassiz, British entomologist, who collected the holotype. Description. Male unknown. Female (Figs. 3, 12). FWL 5.2 mm; WLR 0.35. Vertex dark brown; frons glossy silver. PLB dark brown, short and thin, 1.2 �� scape. Proboscis dark brown. Antenna 1.3 �� FWL. Scape and base of flagellum dark bronze; basal 8���10 segments and then segments 35���50 thickened by raised black scales, which form characteristic brush at about 0.55���0.85 �� FWL; flagellar segments 12 to 30 with white rings; 6���8 flagellar segments following a brush are white, then colour of flagellum abruptly changes to dark brown. Tegula and thorax brown. Forewing grey; basal quarter of forewing monotonous, silver grey; the second quarter densely suffused with both dark brown and light yellow scales (approximately in 1:1 ratio). Base of costa with small dark brown spot. Oblique stripe in the apical part of forewing straight, yellow, extremely narrow and short (not reaching 0.5 �� forewing width); wing apex behind this oblique stripe dark brown, sparsely suffused with yellow scales. Wing margin between the veins R and M2 silver grey, externally bordered by dark brown scales. Fringe brown. Hindwing brown; costal area light brown; fringe light brown apically to light grey basally. Legs dark brown; apices of tibiae and of all tarsomers white; fore and hind tibiae medially with white spots; base of the first tarsomer white. Epiphysis at 0.6, very short, not reaching tip of tibia. Abdomen light brown; distal margins of IV���VI sternites with rows of white scales. Distribution (Fig. 9). Papua New Guinea (Enga).
