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

Nam Lik Ecovillage on Nam Lik River, 18.621469ºN, 102.40847ºE, ~ 200 m, at light, 10–

30. VI.2017, A. Gorochov, M. Omelko ( ZIN) . Paratypes: 2 ♀, same data as for holotype

( ZIN).

DESCRIPTION. Female (holotype). Coloration and structure of body very similar to those of nominotypical subspecies but with some differences: body distinctly smaller; sixth abdominal sternite distinctly larger and with wide (not more or less narrowed) posterior part,

i.e. this sternite approximately as in X. (X.) b. thaica; seventh abdominal sternite clearly less short in median part than in X. (X.) b. thaica and with barely distinct median convexity (in X. b.

beybienkoi , this sternite with very distinct median concavity); genital plate with ventroproximal transverse fold having slight angular median projection ( Fig. 88 ) which visible almost as denticle only from side (in X. b. beybienkoi , this fold indistinct, but ventroproximal median denticle well developed, i.e. visible as denticle from both positions: from side and from behind), and with distinct median keel on more distal part of this plate (this keel indistinct in

X. b. beybienkoi ).

Variations. One paratype with sparse darkish dots on lateral tegminal field (as in holotype of this subspecies, X. b. beybienkoi and X. b. adjacens subsp. n.), but second one almost without such dots.

Male unknown.

MEASUREMENTS. Length (in mm). Body 9–10; body with wings 19–20; pronotum

2.9–3.2; tegmina 15–16.5; hind femora 9.2–9.7; ovipositor 6.8–7.2.

COMPARISON. The new subspecies differs from the nominotypical one in the characters listed above; from X. (X.) thaica, in the distinctly longer median part of the seventh abdominal sternite in female and in the same features of the female genital plate as from the previous subspecies; and from X. (X.) adjacens subsp. n., mainly in the clearly smaller body. From X.

(X.) bituberculata Ebner, 1939 ( China) with the similar female genital plate, the new subspecies is distinguished by the absence of a pair of characteristic tubercles on the female last abdominal sternite.

ETYMOLOGY. This subspecies is named after its type locality.
