MATERIAL. Holotype – ♂, Laos: environs of Luang Prabang [Phabang] Town, forest on left bank of Mekong River, 18.VI 2017, D. Gapon (ZIN). Paratype – Thailand, Loei Prov.,

Phu Ruea, 735 m, 27.V 2010, ♀, V. Bezborodov (ZIN).

DESCRIPTION. Male. General appearance similar to that of A. (A.) superba but with following differences: coloration light brown with dark pattern on head as in this species but also with additional brown areas under antennal cavities and dark narrow and sparse longitudinal stripes on rest part of epicranium (Fig. 62), with light brown pedicel, with light red labrum and rest of clypeus, with pronotum having numerous brown dots and two pairs of dark longitudinal areas on hind pronotal part, with other visible tergites as in female of A.

(A.) superba in coloration, and with light brown sternites and genital plate (but sternites with slightly darkened areas in middle part); hind pronotal lobe covering most part of tegmina, i.e.

reaching distal part of tegminal mirror; last tergite less gradually narrowed to wider posterodorsal lobe which also strongly curved downwards but less long and lacking apical spines (this lobe with a pair of short finger-like lobules only; Figs 111–113 ); cercus with one distomedial spine only ( Figs 111, 113 ); genital plate also similar to that of A. (A.) superba but with less transverse apical lobules having very small subapical styles on ventral surfaces of these lobules ( Fig. 114 ); genitalia with short and stout sclerites clearly fused with each other by their medial (distal) portions, but apical parts of these sclerites not fused with each other as well as slightly widened (rounded at apex) and having a few distinct marginal denticles, and ventroproximal lobules of these sclerites rather large and clearly laterally curved

( Figs 148, 149 , 168 ).

Female. External structure and coloration of body very similar to those of male, but general color of head and pronotum as well as legs and sternites slightly darker, structure of pronotum and tegmina practically as in female of A. (A.) superba , and structure of abdominal apex distinguished from that of this female by somewhat longer genital plate with slightly wider distal part and smaller apical projections ( Fig. 115 ) as well as by barely shorter ovipositor ( Fig. 183 ).

MEASUREMENTS. Length (in mm). Body: ♂ 24.5, ♀ 21; pronotum: ♂ 8, ♀ 6.6; hind pronotal lobe: ♂ 1.8, ♀ 0.9; visible parts of tegmina, ♂ 1.5; hind femora: ♂ 10.5, ♀ 10.5;

ovipositor 8.5.

Genital sclerites from below (reversed): proximal parts (156–169, 171–174); whole sclerites,

but left one reconstructed (170). Left cercus from above (175, 176). Abbreviations: dp –

dorsoproximal lobule (laterobasal part of genital sclerite); vp – ventroproximal (additional)

lobule of genital sclerite [usually more or less curved laterally; sometimes practically not curved (159, 170), strongly reduced or undeveloped (160, 169, 174)].

COMPARISON. The new species is most similar to A. (A.) curvata in the structure of male last tergite and male genital plate, but it differs from the latter congener in the posterodorsal lobe of this tergite less roundly hook-like, male genital plate with smaller styles,

and male cercus with distinctly shorter distomedial spine. From A. (A.) superba , the new species differs in the characters listed above (in A. semicurvata description); from A. (A.)

fastigata, in the male genital plate having very distinct narrowing of its subapical part; from

A. (A.) hainanensis , in the posterodorsal lobe of male last tergite more strongly curved downwards but with apical parts of this lobe not curved forwards (structure of cerci and genital plate in male of A. hainanensis is unclear, because its abdominal apex was not prepared for study; Shi & Xie, 2015: fig. 1); and from the other congeners, in the posterodorsal lobe of male last tergite more strongly curved downwards in combination with the abovementioned character of male genital plate. Belonging of the female from Loei Province of

Thailand to the new species is problematic, because this province is between the type localities of A. (A.) curvata (Phetchabun Province of Thailand) and A. (A.) semicurvata

(northern part of Laos), but this female differs from that of A. (A.) curvata in the genital plate somewhat longer.

ETYMOLOGY. This species name originates from another species name ( A. curvata )

with addition of the Latin prefix “semi-“ (half-).
