status

sp. nov.

Nyctiophylax dosyhpor , new species ( Figs. 3 View FIGURE 3 A–3E)

Holotype: male. Wings and larger part of body yellow fuscous; head, prothorax, antennae yellow. Length of each forewing 4 mm.

Male genitalia. Ventral part of segment IX in lateral view trapezoid. Superior appendages large and round in lateral view. Segment X in lateral view narrow, finger-like; in dorsal view triangular, acutely bilobed apically. Mesoventral process of each superior appendage hook-like, short, with wide base and narrow apex turned downwards. Inferior appendages in lateral view each with small rounded ventral branch and larger tapering dorsal branch with parallel sides and acute apex; in ventral view, with short, rectangular ventral and long, gradually narrowed dorsal branches. Phallus with two pairs of very long spines: dorsal pair (probable parameres) slender and long, directed posterad; ventral pair massive, half as long as dorsal pair, and curved ventrolaterad. Seven strong subparallel ventral spines in apical third of phallus directed posteroventrad.

Diagnosis. Male genitalia of this new species are similar to those of Nyctiophylax argentensis Malicky 1995a from Vietnam, differing from the latter in the shape of the inferior appendages (each of which has a more-acute dorsal branch and a more-prominent ventral branch), very strong serial spines on the phallus (finer and more numerous in N. argentensis ), and a more-slender mesoventral part of each superior appendage.

Holotype: THAILAND, Krabi Province, 18 km N from Krabi, waterfall, 08º14’21”N, 98º55’17”E, height 320 m, UV light traps, 31 January 2014, leg. Melnitsky, Ivanov. (Locality 4) GoogleMaps

Distribution. Thailand (known only from type locality).

Etymology. An indeclinable name with gender agreement irrelevant, from the Russian do syh por (up to now).
