Phyllonorycter gozmanyi — De Prins & De Prins (2007: 49–56; figs 1, 3, 5, 7, 9–11).

Diagnosis. Phyllonorycter gozmanyi is generally similar in appearance to P. farensis , P. pavoniae and P. rhynchosiae . However, it differs from P. farensis by its darker ochreous reflection along costa and presence of black scales at tornus. Male genitalia have some definite distinguishable features. Valva with two lobe projections is unique within the genus. In females, the strongly sclerotized boomerang-like fold sterigma around antrum, membraneaous area and a stellate signum are shared with other species in the rhynchosiae species group. Female genitalia of P. gozmanyi are very similar to those of P. farensis , but the ratio of distance between ostium bursae and anterior margin of segment VII versus the distance between ostium bursae and posterior margin of segment VII is larger than 3 in P. gozmanyi (3.86 and 3.09 respectively) and approximately 2 in P. farensis .

Forewing elongate, ground colour golden ochreous brown with white markings consisting of two transverse fasciae, two costal and one dorsal strigulae; basal streak absent; first fascia at 1/5, angulated, irregular, broader at dorsum, running from base of forewing and forming a patch in which white scales intermix with shiny bronze scales; a row of sparse black scales basally edging first fascia and reaching midline; second fascia at 1/3, angulated, edged with row of black scales basally; first costal and first dorsal strigulae at 2/3, opposite each other, almost of equal size, narrow, comma-shaped, tapering towards apex, touching each other at midline; some black scales stretching irregularly from junction of costal and dorsal strigulae into apical sector; apical sector covered with greyish fuscous brown, intermixed with black and few dirty white scales; second costal strigula at apex, dirty white, comma-shaped, without shine, bordered basally by small patch consisting of 6–8 black scales along costa; posteriorly with row of 4–5 black scales around apex, not reaching costa, and with patch of black scales at middle of apical sector; outer margin of apical sector edged with line of black scales; with second faint parallel line at tornus; fringe long, pale golden with slight shine, preceded by dirty ochreous shade. Hindwing pale fuscous, shiny; fringe shiny pale gold to grey. Fore coxa greyish fuscous; femur dark greyish fuscous; tibia and tarsomeres dark fuscous except pale grey bases of first two tarsomeres and apex of tarsomere V. Mid-leg femur white; tibia dirty white, with two rows of dark blackish brown scales preceded by ochreous brown and forming circular band at base, with two rows of dark blackish brown scales intermixed with ochreous and dark fuscous at 1/2 forming obscure band, and with irregular patch of dark blackish intermixed with fuscous subapically; tarsomeres I–III dirty white, clearly ringed with blackish brown subapically; tarsomere IV golden white; apex of terminal tarsomere pale golden. Hindleg femur pale beige; hind tibia dirty white becoming dark grey dorsally from 1/2 to apex and with row of 4–5 brown scales subbasally, tibial spurs white with slight intermixture of few darker scales, terminated with white hair-like scales reaching 2/3 of tarsomere I; apices of tarsomeres I–III marked with dark brown scales, terminal tarsomeres white.

Abdomen: Greyish brown dorsally, white ventrally. Eighth sternum of male slightly tapering to rounded apex.

Male genitalia ( Figs 262–264 View FIGURES 259–264 ). Tegumen lightly sclerotized, apex conical, tuba analis not protruding. Valvae symmetrical, valva of moderate width, 1.5× longer than eighth sternum, gradually widening, 1.5× wider at apex than at base, rounded apically; costal margin more thickly sclerotized, medially with sparse short setation from middle to apex; each valva with bilobed projections extending from base to apex; ventral projection gradually broadening at 2/3, tapering distally, with rounded apex; both projections forming a 90° angle; dorsal (upper) projection broadening from very narrow bases, forming a triangular pointed peak at ¼, followed by slight depression, then to both margins of projection running parallel and connecting with apex of valva; both projections covered medially with sparse setae becoming slightly thicker at apical sector of dorsal projection; dorsal projection slightly more thickly sclerotized than ventral one; median surface of valva overlapping with surface of dorsal projection.
