Diagnosis.
The new species is unique for the possession of four spine-like projections of the female subgenital plate: one pair from the end of the upcurved baso-lateral areas, and the other pair from the end of the central disc. Moreover, the dorsal ovipositor valves have the dorsal margin markedly convex but not strongly widened.
Description.
Coloration of face uniformly pale, of general color; mandibles of same color, only at, in situ hidden, tip black; antennal scrobae light to medium brown (
Fig. 4J
). Femora with the following number of spines on ventral margins: (1) a 6, p 7–8; (2) a 7–8, p 5; (3) a 13, p 13–15 (n=1).
Male unknown.
Female. Subgenital plate with convex ventral surface but in lateral areas curved more strongly dorsad; lateral margins convex behind basal area, the marginal lateral areas divide from the disc and form a pair of stout, rounded projections with approaching margins and acute tip; in the further curse the lateral margins then run in a bow to the somewhat elevated central area; the central area divides at end into a pair of apical, spine-like projections that are separated by a wide and straight interspace with subtruncate bottom (

,
7C
). Ovipositor only little longer than body but for one third longer than the hind femur, laterally compressed; behind basal constriction with dorsal margin convex and moderately elevated around mid-length, in apical area straight and narrow (

Etymology.
The new species is named for the presence of four spine-like projections of the female subgenital plate, from the Latin words
quaternio, quattuor
= four and
spina
= spine.
