Reserve, 10º32ʹ N, 107º29ʹ E, 50 m, VI 2007, 1 ♀, A. Abramov ( ZIN) .

DESCRIPTION. Male (holotype). Body structure and coloration very similar to those of

A. (E.) signata but with following differences: ventral half of head rostral tubercle and upper half of clypeus uniformly dark brown (i.e. of same color as anterior surface of epicranium);

general coloration of head dorsum and all tergites slightly darker than in this species, almost greyish brown; tegmina including mirror somewhat smaller, but posterior edge of pronotum reaching base of mirror (as in male of A. signata ); last tergite with slightly narrower distal part of posterodorsal lobe and with distinctly less deep posteromedian notch; cercus also short, but its distal lobules shorter than in this species (dorsal of them moderately wide and with angular apex; ventral lobule clearly shorter and thinner, with small denticle at apex; both lobules directed medially and separated from additional roundly tubercle-like lateral lobule by additional and rather deep concavity; Figs 83–85 ); epiproct small, roundly triangular,

directed downwards and slightly forwards, having a pair of posterodorsal finger-like processes in basal part ( Fig. 84 ); paraprocts more or less similar to those of A. (E.) namlik ;

genital plate with somewhat wider apical part having very shallow but distinctly wider notch between styles ( Fig. 83 ); genitalia with distinctly longer sclerites having slightly widened distal portions which arcuately curved downwards and lacking distinct denticles ( Figs 143,

144); proximal parts of these sclerites partly fused with each other and having very small

(short) ventroproximal lobules directed more or less laterally ( Figs 143 , 163 ).

Variations. Second male with dark anterior surface of epicranium having distinct lighter

(brown) dots, and with dark mandibles having some brown to almost light brown marks.

Female. General appearance as in males, but head without brown dots on dark brown areas, and tegmina invisible or almost as in female of A. (E.) namlik ; abdominal apex approximately as in female of A. (E.) signata , but cerci with slightly thinner and longer apical parts, genital plate without median membranous area but with longer and less hooked apical lobules as well as with narrower space between them ( Fig. 86 ), and ovipositor barely more arcuate (less straight; Fig. 180 ).

MEASUREMENTS. Length (in mm). Body: ♂ 22–24.5, ♀ 21–27; pronotum: ♂ 6.3–6.5,

♀ 6.4–6.7; hind pronotal lobe: ♂ 1.2, ♀ 1.1–1.2; visible parts of tegmina: ♂ 1.4–1.7, ♀ 0–

0.3; hind femora: ♂ 10.7–11.5, ♀ 12–12.5; ovipositor 11–12.

COMPARISON. The new species is most similar to A. (E.) signata and A. (E.) boku in the body coloration (including presence of four darkened spots on pronotum) but well distinguished from them by the structure of male cercal lobules; these lobules are shorter than in these species (especially ventral lobule) and similar to those of A. (E.) styliana, but the latter species differs from A. (E.) parasignata in the sclerites of male genitalia shorter,

more stout and with more strongly curved distal portions. From all the other congeners, the new species differs in the characteristic coloration, shape of structures of male abdominal apex and peculiarities of female genital plate.

ETYMOLOGY. Name of the new species originates from the species name A. signata and Latinized Greek prefix “para-” (near).
