Parancistrocerus irritatus Giordani Soika, 1972 Parancistrocerus irritatus Giordani Soika, 1972 : 103 , fig. 3, male, “ Sikkim ” (ZMB); Giordani Soika, 1994 : 154 (key), 164. Diagnosis : Male: Distance between clypeal teeth much shorter than basal width of clypeus, area between clypeal teeth more closely emarginate at apex; antennae with 11th article short, not longer than wide; apical antennal article very long, and its apex reaches far beyond base of 11th article (see Fig. 3 of Giordani Soika, 19 72: 102); superior carina of propodeum little developed and irregular, hence no true dorsal surface of propodeum clearly separated from posterior; T2 with apical margin prolonged in middle; mesosoma 1.5x longer than wide; T2 about 1.25x longer than wide, slightly round at sides. Colour description : Body black with yellow and ferruginous to yellow-ferruginous markings. Yellow portions: mandible; clypeus; inter antennal space; ocular sinus; ventral side of scape; linear mark on tempora; wide band along anterior margin of pronotum; front and rear ends of tegulae; parategulae; metanotum; large mark on mid and hind coxae; apex of femur and outer face of fore and mid tibiae; regular band at apex of T1, extended to side margins; wide band at apex of T2 and narrow band at apex of S2; apical margins of S3 and S4. Ferruginous to yellow-ferruginous: antennae; posterior margin of pronotum; tegulae except yellow markings; legs except yellow markings. Fore wing infumate along costa, with large dark spot at apex. Length (H+M+T1+T2): 9-9.5 mm. Distribution : India: Sikkim. Remarks : No specimens were available for our studies, hence the description was taken from Giordani Soika (1972) .
