Rhotana globosa Zelazny , sp. nov.

( Fig. 226)

Description. Forewings 2.1 times longer than wide, length about 4.8 mm. Colour stramineous to light brown; rostrum and a diffuse, longitudinal band along frons and clypeus darker, tinted with orange; fore tibiae, - tarsi, and tips of fore femora reddish-brown. Forewings with eight round, black marks lining in pairs the apical cross-veins between Cu, Cu1, Ms1b, and Ms1a; area in front of markings and some spots in between them covered with white powder; rest of forewings glassy, faintly yellow-brown, but with hyaline areas, e.g. in basal quarter, and before, and after apical cross-veins; a red mark around last subcostal sector; veins in between markings, apical cross-veins between Sc, R and M, apical margin, and a central section of costa red; remaining veins stramineous. Hindwings colourless. Rostrum surpassing hindcoxae; facial carinae meeting at very base; subantennal processes and lateral carinae of pronotum well developed. Forewings with costal margin and Sc nearly straight; Sc+R fork slightly before middle of wing; Ms1 branched at apex of basal median cell, both branches nearly parallel; apical portion of Ms1b connected to Cu1 by a cross-vein; base of Ms1a connected to M by a cross-vein forming a trapezoid cell at base of Ms1. Male genitalia with pygofer narrow. Apical part of aedeagus ending in two rounded lobes, the right one slightly shorter and partly overlapping the left one.

Etymology. The species name is a Latin adjective (globosus, -a, -um = spherical).

Type material. Holotype ♂ (forewing 4.8 mm), INDONESIA, WEST PAPUA; labels: 1) NEW GUINEA: NETH./ VOGELKOP: Fak Fak / S. coast of Bomberai / 10–100 m., VI-1-1959 2) J.L. Gressitt / Collector ( BPBM).

Distribution. New Guinea (West Papua).

Diagnosis. Rhotana globosa resembles closely R. pavo (Bierman) from Sumatra and Borneo. It can be distinguished by the forewings having red apical crossveins as well as a conspicuous red mark around the last subcostal sector, and by the veins in between the black marks not lined with red (although the veins themselves are red). In the male aedeagus the two terminal lobes are nearly of equal length.
