DESCRIPTION. Male. Coloration light yellowish (light greenish in living condition) with numerous very small brown spots on proximal part of antennal flagellum,

greyish brown to blackish rest of this flagellum, intensively yellow stripe on each tegmen along its anal edge, partly brown to brownish dorsal surfaces of long outer spines on fore tibia, light brown narrow marks on dorsal surface of long inner spines of this tibia, brown dot on each apical lobule of hind femur, brownish dorsal spinules of hind tibiae, blackish marks on ventral surfaces of subapical segments of fore and middle tarsi as well as on all segments of hind tarsus, and darkened apical spines

(spurs) of hind tibia. External structure typical of Asiophlugis Gorochov, 1998 , but pronotum with hind lobe barely inflated and covering basal areas of tegmina, fore leg with 3 outer and 4 inner spines on femur as well as 4 pairs of long spines and a pair of short ventroapical spinules on tibia, middle leg with latter spinules only,

hind leg without spines or denticles on femur as well as with a pair of rows from not very numerous dorsal spinules and 2 pairs of short apical spines on tibia,

tegmina reaching cercal apices and with stridulatory apparatus as in Fig. 6 , hind wings distinctly protruding beyond tegminal apices, last tergite with very short and barely bilobed posteromedian lobe, epiproct rounded and projected behind this lobe,

paraprocts also rounded but smaller than epiproct, proximal portion of cercus rather long and slightly arcuate as well as with small and spinule–like ventrobasal hook directed medially, distal portion of cercus shorter than proximal one and curved laterally as well as somewhat widened at base ( Figs 25, 26 ), and genital plate short and with rather long styles as well as with moderately wide and very shallow notch between them ( Fig. 27 ); genitalia membranous.

Female. General appearance as in male, but stridulatory apparatus absent, and last tergite and cerci unspecialized; genital plate short, with widely truncated apical part and 3 folds (a pair of ventrolateral longitudinal keels and one transverse fold between them and apical part of this plate; Fig. 28 ); ovipositor as in Fig. 8 .

MEASUREMENTS. Length (in mm). Body: ♂ 10, ♀ 10.5; body with wings: ♂

13, ♀ 14.5; pronotum: ♂ 3.4, ♀ 3.4; visible parts of tegmina: ♂ 7.5, ♀ 8; hind femora: ♂ 11, ♀ 12; ovipositor 5.3.

COMPARISON. The new species is similar to A. thaumasia Hebard, 1922 and

A. malacca Gorochov, 1998 in the male abdominal apex and female genital plate,

respectively. However, it is distinguished from A. thaumasia by the posteromedian lobe of last male tergite shorter, male epiproct visible from above, male cerci with the distal portion clearly shorter than proximal one (vs. these portions almost equal in length), and male genital plate with the posterior edge between styles notched but not convex or almost straight; from A. malacca , the new species differs in the female genital plate with the lateral edges of distal part more or less convex (not concave),

and with a distinct transverse fold and narrow longitudinal keels (in A. malacca and

A. thaumasia , such fold is absent, and there are a pair of longitudinal inflations instead these keels; see Figs 28, 30, 31 ).

ETYMOLOGY. Name of this species is the Latin word “legitima” (real, correct).
