MATERIAL. Holotype – ♂, Laos: Vientiane Prov., ~ 70 km NNW of Vientiane

City , Nam Lik Eco Vill. on Nam Lik River, 18.61469ºN, 102.40847ºE, ~ 200 m, secondary forest, at light, 10–30.VI 2017, A. Gorochov, M. Omelko .

DESCRIPTION. Male. Coloration yellowish (light greenish in living condition)

with light brown eyes and very sparse and small spots on antennal flagellum, brownish stripe on each tegmen along its anal edge (but mirror and nearest lateral, medial and basal membranes transparent) and several rather small spots on tegminal lateral field more or less along its median axis as well as dorsal surface of almost each tibial spine of fore and middle legs, a pair of dark brown apical dots on hind femur, and slightly darkened spines of hind tibia and areas on subapical segment of all tarsi.

Body structure similar to that of other representatives of this subgenus, but hind wings insignificantly protruding beyond very long tegmina, last tergite with deeper posteromedian notch and very small and practically non-bifurcated posterodorsal process (apex of this process somewhat notched; Fig. 56 ), epiproct rather small and elongately oval as well as directed downwards, paraprocts rounded and similar to epiproct in size, cerci symmetrical and moderately short, distal half of each cercus with elongate dorsoapical lobule (directed backwards and slightly medially) as well as with similar ventroapical lobule partly curved medially and having angular tooth at base of its medial surface ( Figs 54, 56 ), proximal half of each cercus with small but distinct angular medial projection ( Figs 54, 56 ), genital plate rather small and simple ( Fig. 55 ), and genitalia membranous.

Female unknown.

MEASUREMENTS. Length (in mm). Body 9; body with wings 18.5; pronotum

3.2; tegmina 14.3; hind femora 8.5.

COMPARISON. The new species is clearly distinguished from all the other species of Furcixizicus by the unpaired posterodorsal process of male last tergite notched at the apex but not distinctly bifurcated, by the ventroapical lobule of male cercus with a medial tooth (such tooth in other representatives of this subgenus is absent, located on the basal part of dorsoapical cercal lobule or between dorso- and ventroapical cercal lobules), or by the male genital plate less narrowed in the distal half [only from X. (? Furcixizicus ) fallax Wang, Jing, Liu et Li, 2014].

ETYMOLOGY. The species is named in honor of the lepidopterist M.M. Omelko for his help during my field work in Laos.
