Etymology. The specific name is derived from two Latin words: the prefix ir – (not or without), and ramulus (small branch), with reference to paramere of this species basally not bifurcate. Recognition. This species clearly differs from the similar P. punctifrons Shuckard, 1838 and all other members of the genus by the combination of the following characters: ventral margin of clypeus (Fig. 3) in female broadly and roundly protruding in the middle, prominence of clypeal ventral margin (Fig. 4) in male bluntly toothed medially; branch of sternum VIII (Fig. 5) subapically protruding inwards; paramere of genitalia basally not bifurcate; branch of sternum VIII not protruding inwards and paramere of genitalia basally bifurcate in P. punctifrons. Description. Female body length 7.5–8.5 mm; male body length 7.5 mm. Body black; palpi, mandible apically, ventral margin of clypeus medially and outer margin of tegula dark brown. Body with long, erect silvery setae, setae on clypeus and ventral frons comparatively denser, those on apical band of each gastral tergum more obvious and denser laterally, and inconspicuous medially; fore wing (Fig. 10) with three submarginal cells Ƥ (Figs. 1, 3 & 8). Head: Clypeus, frons and vertex with dense punctures, those on frons large and subcontiguous; eye incision wide and shallow; frons dorsally without medial longitudinal furrow, ventrally with medial longitudinal carina; clypeus (Fig. 3) medially protruding, ventral margin broadly and roundly protruding in middle; apex of each antennal flagellomere wider than its base; HW: HL: IOD V:= 125: 42: 45; IOD S= 45: 60; OOD: OD: POD= 7: 7: 7; flagellomere I= 26; flagellomere I, II, III= 26: 25: 22. Thorax: Thorax punctate, punctures obviously sparser, larger and deeper than those on head, PD Gaster: Tergum I somewhat constricted apically in dorsal view; gaster with minute, sparse punctures, interspaces between punctures smooth and shiny; translucent apical bands of terga I-IV obviously wider than diameter of hindtarsomere I. 3 (Figs. 2–7). Similar to female; differing from female as follows: ventral margin of clypeus (Fig. 4) toothed somewhat bluntly in the middle; transverse ridges on propodeal dorsum not arched in the middle, straighter than in female; HW: HL: IOD V= 123: 37: 46, IOD S= 46: 55, OOD: OD: POD= 8: 8: 10; flagellomere I= 20; flagellomere I, II, III= 20: 16: 15, branch of sternum VIII (Fig. 5) subapically protruding inwards; paramere of genitalia (Figs. 6–7) basally not bifurcate.
