Kokeshia oroszi sp. nov.

( Figs. 6 , 14-18 )

Type locality. Thailand, Trang Province, Khao Chong Botanical Garden [ca. 7°33′20.35″N and 99°47′38.28″E].

Type material. HOLOTYPE: J (macropterous), ‘ THAILAND: Prov. Trang, / Khao Chong Bot. Garden, / at the staff center // at light, 27. 11. 2003 / leg. A. Orosz & Gy. Sziráki’ (glued on the triangle, abdomen preserved in intact condition in plastic microvial with glycerine, pinned with the specimen) ( HNHM).

Description. Macropterous male. Colour. General body colour, including appendages, light brown; head and anterior half of pronotum (excluding collar) distinctly darker brown.

Structure. General facies and external morphology as Kokeshia martensi Štys, 1985 , except when indicated otherwise.

Head strongly declivent, interocular distance about 0.87 times as wide as diatone, eyes small. Pronotum about 1.87 times as wide between humeri as median length. Fore wing tegminal, surpassing greatly apex of abdomen; fused apical portion of free distal remigial vein clavately terminating before margin; vein distally delimiting marginal postfractural cell strongly oblique. Pregenital abdomen ( Fig. 6 ) symmetrical; subgenital plate (sternum VII) relatively narrow, symmetrical, generally subtriangular, only slightly wider than pygophore.

Male terminalia. Tergum VIII ( Fig. 14 ) subdivided into asymmetrical hemitergites; left hemitergite with a slender, flagelliform, curved process gradually narrowing towards apex; right hemitergite triangularly projecting posteriad, right laterotergite could not be observed in situ. Pygophore ( Fig. 14 ) with slight dextral asymmetry, proximally separated by segment X. Proctiger ( Fig. 14 ): segment X directed slightly dextrally, simple; segment XI elongate, tubular, slightly narrowed subapically, dextrally and dorsolaterally protruding, surpassing lateral outline of pygophore in dorsal view. Parameres asymmetrical ( Figs. 14-18 ); left paramere ( Figs. 15-16 ) with an oval base provided with a distinct anterior and posterior extension, anterior extension large, lobe-like, oval, directed mesad, hypophysis simple, finger-like, directed mesad; right paramere ( Figs. 17-18 ) with a wide, subtriangular basal extension projecting posteriad, hypophysis finger-like. Phallus ( Fig. 14 ) examined only in situ; with a tubular, curved, relatively narrow apical part protruding from pygophore, external part forming one incomplete coil, provided with a crest-like sclerite.

Measurements (holotype) (in mm). Body length from apex of head to apex of fore wings as visible in dorsal view 1.04; width of head 0.314, interocular distance 0.272; length of pronotum along meson (including collar) 0.291, length of collar along meson 0.049, humeral width 0.543, length of fore wing 0.872.

Female. Unknown.

Differential diagnosis. The male of this new species is similar to that of K. esakii in the relatively narrow subgenital plate and the large, lobe-like anterior extension of the left paramere; however, K. oroszi sp. nov. can be readily distinguished from the latter species, among others, by the very long and narrow apical part of phallus forming about 1.5 coils outside the pygophore. The new species is uniquely characterized within the genus by the small body and the simple, flagelliform, curved process of left hemitergite of tergum VIII in male.

Etymology. This new species is dedicated to my friend and colleague András Orosz (Hungarian Natural History Museum, Budapest), collector of the holotype.

Locality and habitat notes. The specimen was captured at light in a clearing surrounded by a rainforest.

Distribution. Thailand.
