MATERIAL. Holotype – ♂, Thailand: Loei Prov., Phu Ruea , 735 m, 28.V 2010, V.

Bezborodov ( ZIN).

DESCRIPTION. Male. Body rather small and slender. Coloration light brown with following pattern (Fig. 64): most part of epicranium, maxillae, labrum, venter of thorax and six proximal sternites of abdomen yellowish; anterior surface of epicranium (including ventral part of rostral tubercle), ventromedial parts of antennal cavities and areas on mandibles blackish; ventromedial parts of scapes, distal part of labrum, a pair of bands on pronotal lateral lobes along lateral edges of posterior half of disc, longitudinal area on each lateral side of abdomen, each lateral part of metanotum and two dorsal spots on fore tibia brown; clypeus and rest of distal halves of mandibles reddish; numerous dots on all tergites whitish. Head rather narrow, almost as in A. (A.) archaica (Fig. 64); pronotum with lateral lobes similar to those of A. (A.) superba and A. (A.) semicurvata , and with hind lobe slightly concave posteriorly; tegmina almost completely covered with this lobe, i.e. only small distal parts of tegmina visible (these visible parts widely rounded); last tergite with wide posterodorsal lobe divided into a pair of narrower lobes by very deep and rather wide posteromedian notch (each distal part of latter lobes narrow, with hooked apical spine curved medially and slightly downwards, and with small subapical spinule directed downwards and somewhat medially

( Figs 116, 117 ); epiproct small, almost rhombic in shape and with rather large concavity in centre; paraproct also small and simple, with concave posterolateral surfaces and somewhat elevated medial parts; cercus similar to that of A. (A.) semicurvata but with much longer distomedial spine (this spine is longer and thicker than even in A. curvata ; Fig. 116, 118 );

genital plate almost elongately rectangular, with normal styles and rather large (but not deep)

and almost angular notch between them ( Fig. 116 ); sclerites of genitalia rather thin, having medial (distal) portions connected with each other by very narrow membrane from base of proximal portions of these sclerites to their apical parts, and lacking distinct ventroproximal lobules (a pair of small additional semimembranous plates located near apical parts of genital sclerites developed; Figs 151, 152 , 169 ).

Female unknown.

MEASUREMENTS. Length (in mm). Body 22; pronotum 5.8; hind pronotal lobe 1.2;

visible parts of tegmina 0.4; hind femora 10.5.

COMPARISON. The new species is somewhat similar to A. (A.) multicurvata having the posterodorsal lobe of male last tergite deeply bifurcate, and male cercus with one distomedial spine only, but A. (A.) forceps is distinguished from the latter species by the blackish face

(vs. face is not darker than rest of head), longer lateral parts of posterodorsal lobe of male last tergite, deeper notch between them, and male cercus much shorter and not S-shaped. From all the other congeners, A. (A.) forceps differs in the posterodorsal lobe of male last tergite deeply bifurcate and very characteristic (forceps-like) in shape.

ETYMOLOGY. The species name is the Latin word “forceps” (ticks, forceps) given in connection with the forceps-like lobes of male last tergite.
