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

Nam Lik Eco Village on Nam Lik River , 18.61469º N, 102.40847º E, ~ 200 m, secondary forest, on forest bush at night, 10–30. VI 2017, A. Gorochov, M. Omelko ( ZIN). Paratypes :

same data as for holotype, 1 ♂, 2 ♀ ( ZIN) .

DESCRIPTION. Male (holotype). Body medium-sized for this genus. Coloration almost uniformly greyish brown but with more or less greyish-yellowish venter and following marks:

mandibles blackish; small spot at each base of fore and middle tibiae brown; inner halves of scapes and area under rostral apex as well as two spots on dorsal half of fore tibia dark brown;

very numerous dots on other parts of body whitish (Fig. 56). Hind lobe of pronotum covering most part of tegmina; only very short and widely rounded apical tegminal parts visible behind posterior edge of this lobe. Last tergite with short but wide and roundly angular posterodorsal lobe having moderately small angular posteromedian notch; cercus moderately elongate and rather thin, with almost straight proximal half and medially curved distal part which flattened and divided into two flat but not very narrow lobules having small darkened apical denticles

( Figs 70–72 ); epiproct simple, small, triangular, directed downwards; paraproct also small but with almost globular apical lobule; genital plate with normal styles and rather deep angular notch between them ( Fig. 70 ); genitalia with sclerites rather thick, connected together by narrow semimembranous area, movable in relation to each other, with one rather large apical denticle on each sclerite ( Figs 134–136 ), and with distinct ventroproximal lobule (vp) on subbasal part of each sclerite (this lobule directed forwards or laterally in different positions of these sclerites; Figs 134 and 135 , 156 and 157 ).

neofurcata sp. n.; 78 – A. (? E.) bangkirai sp. n.; 79–82 – A. (E.) signata sp. n.; 83–86 – A.

(E.) parasignata sp. n.; 87–89 – A. (E.) denticulata sp. n.; 90 – A. (E.) boku Helfert et

Sänger; 91 – A. (? E.) phetchaburi sp. n.; 92–96 – A. (Perianelytra) propria propria Gor.

(after Gorochov, 1994). Male abdominal apex from above (70, 75, 79, 83, 87), from side (71,

76, 80, 84, 88), as well as from above (92) and from side (93) but without genital plate; distal part of left male cercus from behind (72, 73, 77, 81, 85, 89); female genital plate from below

(74, 78, 82, 86, 90, 91, 96); male epiproct from behind (94); distal part of male genital plate from above (95).

Variations. Second male with distal cercal lobules partly fused with each other ( Fig. 73 ),

and with three apical denticles on right genital sclerite.

Female. General appearance as in males, but anterior surface of epicranium in one female with somewhat darker median band, tegmina visible as a pair of extremely small lateral scales behind pronotum, last tergite almost without posterodorsal lobe but with moderately deep or rather shallow posteromedian angular concavity, paraprocts without distinct lobules,

and cerci smaller and rather thin as well as elongately conical; genital plate transverse,

somewhat laterally inflated, with posterior edge as in Fig. 74 ; ovipositor rather short and moderately arcuate ( Fig. 177 ).

MEASUREMENTS. Length (in mm). Body: ♂ 24–25.5, ♀ 25–29; pronotum: ♂ 7–7.3, ♀

6.4–6.6; hind pronotal lobe: ♂ 1.4–1.5, ♀ 0.9–1; tegmina, visible parts: ♂ 0.6–0.7, ♀ 0.1–

0.2; hind femora: ♂ 12.4–12.7, ♀ 12.5–13; ovipositor 8.5–8.8.

COMPARISON. The new species differs from the other species of Euanelytra in the male last tergite having its posterodorsal lobe shorter and wider than in A. localis , A. indigena and

A. jinghonga as well as more notched than in A. adjacens , male cerci less shortened than in

A. stylata as well as with the both distal lobules shorter than in E. furcata and similar in length or shape (compared to A. malaya , A. boku , A. compressa and A. spinia ), male genitalia with characteristic shape of sclerites, and female genital plate transverse and partly inflated as well as with short and roundly bilobate posteromedian lobule (however, it is necessary to note that in A. dividata from Thailand, this plate is rather similar in shape but with larger posteromedian notch, and A. punctata from Burma was described after a female nymph having acute lobes at the apex of this plate).

ETYMOLOGY. This species is named after the Nam Lik Eco Village, its type locality.
