MATERIAL. Holotype – ♂, Philippines: Busuanga I. (near Palawan I.), environs of

Coron Town on southern coast, secondary forest, 21–23.II 2004, A. Gorochov ( ZIN).

DESCRIPTION. Male. General appearance similar to that of A. (S.) nigra but with slightly less slender body which almost as in A. (A.) archaica in shape (Fig. 65). Coloration greyish-

brownish but very light and with following pattern: ventrolateral parts of rostral tubercle,

ventromedial parts of both antennal cavity and scape, epicranial area between antennae,

vertical (median) band running from this area to middle of anterior surface of epicranium dark brown; rest of this surface and most part of clypeus light brown; stripe on epicranium along dorsal edge of antennal cavity as well as marks on pedicel brown; most part of mandible blackish; distal part of labrum reddish brown (Fig. 65); tegminal part, visible behind pronotum,

with yellowish (almost whitish) venation and greyish brown to dark brown membranes; legs and thoracic venter yellowish with dark brown dorsal marks on fore tibia, small brown subapical spot on middle tibia, and slight greyish reticular pattern on middle and hind femora as well as on hind tibia; abdomen light greyish brown (barely darker than head and thorax) with numerous whitish dots on tergites and almost yellowish genital plate. Apex of rostral tubercle distinctly not reaching apices of scapes; pronotum similar to that of A. (A.) forceps but with somewhat more concave posterior edge of hind lobe covering only basal part of tegmina;

tegmina almost reaching posterior edge of metanotum, widely rounded posteriorly, with mirror completely visible behind pronotum; last tergite almost without posterodorsal lobe but having a pair of small and obtuse projections around rounded posteromedian notch (these projections practically not protruding beyond base of epiproct, because epiproct articulated with posterior edge of this tergite); epiproct directed backwards, with basal part rather narrow and having deep median groove on dorsal surface, and with distal part strongly widened and flattened as well as roundly truncate at apex ( Fig. 119 ); paraproct rather small and simple, but with short rounded lobule at apex; lateral branch of cercus larger than medial one, with long and thin apical hook having small acute denticle at apex, and with moderately long subapical angular projection; medial branch of cercus distinctly shorter and thinner, almost spine-like, located near cercal base and directed almost at right angle to previous branch ( Figs 120–122 ); genital plate moderately elongate and almost rectangular, with normal styles and shallow rounded notch between them ( Fig. 123 ); sclerites of genitalia moderately thin and not fused with each other, with ventroproximal lobules located in more anterior (more basal) position than in A.

(S.) nigra and less strongly curved laterally ( Fig. 173 ), and with apical parts rounded, not widened and lacking denticles ( Figs 153, 154 ).

Female unknown.

MEASUREMENTS. Length (in mm). Body 29.5; pronotum 7.7; hind pronotal lobe 1;

visible parts of tegmina 2.5; hind femora 15.

phetchaburi sp. n.; 183 – A. (Anelytra) semicurvata sp. n.; 184 – A. (Stenanelytra) nigra nigra (Ingr.) ; 185 – A. (Stenanelytra) nigra khmerica subsp. n.; 186 – A. (Stenanelytra) angusticauda sp. n.; 187 – A. (? Euanelytra ) bangkirai sp. n.; 188 – A. (Perianelytra) propria propria Gor.

COMPARISON. The new species is similar to A. (S.) nigra in the structure of male abdominal apex (including shape of its epiproct), but it clearly differs from the latter species in the smaller darkened part of epicranial face, distinctly longer subapical angular projection of male cercus, and ventroproximal lobules of male genital sclerites less curved and located more basally.
