description: Lissochlora klausi Viidalepp & Lindt, sp. n. (Figs 1, 3, 5)
Material: Holotype: male, French Guiana, Kaw Mts., Amazone Nature Lodge, 13– 20.11.2006, leg. J.& V. Viidalepp (slide 7765)(ID: IZBE0121097); paratypes, 3♀, the same data but (ID: IZBE0121095) and wuth slides 7766 (ID: IZBE0121093), and 8844 (ID: IZBE0121094). The type specimens are deposited in the IZBE collection at the Estonian University of Life sciences (Tartu, Estonia) and in the Estonian Museum of Natural History (Tallinn, Estonia) and registered in the PlutoF database.
Diagnosis: The new species is similar with Lissochlora purpureotincta (Warren, 1900) from Ecuador, differing in having broader wings, shorter palpi, and much longer male antennal rami. The socii are shorter in the male genitalia and the configuration of the distal costal process of valva is different in L. purpureotincta and L. klausi, sp. n. (compare Figs 3 and 4).
Description: Wing span 21 mm in male, 24–25 mm in females (Fig. 1). The frons is brown with lower corners paler, the palpi are darker below, short and pointed in male but 0.6 mm long in females. Male antennae are bipectinate, the rami 0.45 mm long on the tenth segment. The hindtibial process is 0.6 mm long. The interantennal fillet is broad, white, the vertex green, a broad dark rosy line between. The metathorax is grey, the white blotch on tergite A1 is quadrangular, broader than long, edged red-brown, the dorsum of tergite A2 is green, without a blotch, the white blotch on the tergite A3 is large and edged red-brown; the dorsum of the fourth tergite is grey with a smaller white spot. The wings are green, the ante- and postmedian lines represented by pairs of brown and white vein-spots of equal size. The postmedial spots are white on the hindwing. The red-brown marginal line is bold, sometimes slightly lunulate, disrupted by pale spots on the veins; the fringe is white in its basal third, greyish distally, strongly chequered brownish against vein ends, retaining a row of slender, oval, white streaks.
Male genitalia (Fig. 3): The uncus is sclerotised and conical with a stick-shaped apical process; the socii are broad at the base, slender at the apex; the process of the gnathos is spoon-shaped but slender; the costa of the valva is broad, broader than the valvula, produced leg-shaped rather than bifid beyond the costal edge as in L. purpureotincta but nearer to the valvula. The tip of the costa is not upcurved in other members of the L. albociliaia species group. The coremata hairscales are blackish. The last abdominal sternite is distally bilobed, twice broader than long. The aedeagus is slender. Female genitalia (Fig. 5): The ductus bursae is as long as the corpus bursae, the signum is present.
Biology and distribution. The species inhabits tropical rainforests in French Guiana.
Derivatio nominis. The new species is named after Klaus, the baby boy in the family of the first author’s grandson Erki Viidalepp.
