MATERIAL. Holotype – ♂, Vietnam: Gia Lai Prov., ~ 40 km N of Kannack Town ,

environs of Tram Lap Vill., primary forest, 20–24.IV 1995, A. Gorochov ( ZIN).

DESCRIPTION. Male. General appearance similar to that of A. (E.) namlik including coloration of head (Fig. 58) and tergites but with following characteristic features: pronotum with lateral lobes more similar to those of A. (E.) neofurcata in shape; hind pronotal lobe completely covering stridulatory areas of tegmina (only widely rounded posterior parts of tegmina, which located behind mirror, visible from above); last tergite with a pair of moderately narrow and long posterior lobes separated from each other by deep and rather wide posteromedian notch; distal parts of these lobes arcuately curved downwards, rounded apically and having several small marginal denticles ( Figs 87, 88 ); epiproct small and simple (almost triangular), directed downwards and slightly forwards, with basal part visible from above between posterior lobes of last tergite; paraprocts also small and simple (roundly triangular),

without distinct lobules; cerci similar to those of A. (E.) namlik but slightly shorter and with distal parts curved medially, flattened, somewhat widened and having two apical denticles

(possible traces of two distal cercal lobules: dorsal of these denticles spine-like, but ventral one distinctly shorter; Fig. 89 ); genital plate with rather deep and angular posteromedian notch between normal styles ( Figs 87, 88 ); genitalia with sclerites having rather wide proximal two thirds located very near each other at long distance, with narrower and almost

S-shaped distal thirds of these sclerites having a few denticles at each apex, and with short ventroproximal lobules of these sclerites located near each other (i.e. practically not curved laterally; Figs 137, 138 , 159 ).

Female unknown.

MEASUREMENTS. Length (in mm). Body 26.5; pronotum 7; hind pronotal lobe 1.8;

visible parts of tegmina 1.1; hind femora 11.5.

COMPARISON. The new species is clearly distinguished from all the other congeners by the presence of a pair of long and denticulate posterior lobes on the male last tergite, and by the male cercus with characteristic shape of its distal part (this part is with the distal lobules fused with each other not less strongly than in paratype of A. namlik ).

ETYMOLOGY. Name of the new species is the Latin word “denticulata” (denticulate),

because this species has the male last tergite with denticulate lobes.
