Pharynxbipartite, consisting of a slender muscular anterior section, which bears a minute (but perceptible) mucro at its beginning (observed in the four specimens examined); a deep constriction separating both sections; basal expansion nearly cylindrical, occupying 63-71% of total neck length and surrounded by a distinct spiral muscular sheath.

, who provided measurements of two females and two males. The Vietnamese material herein examined perfectly fits the general morphology of the type material (females) (unfortunately, male was not collected in Vietnam), especially concerning the genital system. Moreover, the morphometrics of the two Indian populations and the Vietnamese one largely overlap in spite of the few number of available specimens in the three cases. The ranges of several ratios and measurements, however, are significantly widened, for instance c = 50-70 vs 53-55 in type material, V = 47-57 vs 52-54, etc. Thus, no reasonable uncertainty persists on the identity of this material.
