(A) Head and mesosoma, lateral aspect; (B) face, oblique aspect, showing square black mark; (C) metasomal tergites 1 and 2, lateral aspect; (D) fore wing second submarginal cell; (E) base of hind wing showing large glabrous area distal to vein cu-a.
Colouration
Head yellow with square mark on face as well as mid-longitudinal stripe on upper part, frons medially and vertex and occiput black. Meso- and metasoma black except for a few dark brown-black marks and apical half of antenna which is brown yellow, fore and
middle legs which are cream yellow, the latter with distinct dark brown mark on coxa and baso-ventral part of femur. Wings smoky yellow with distal margin grey brown.
Notes
Closely related to
I. laboriosus
and
I. albitarsus
sp. nov.
differing from both in being almost entirely black and in having the antennae yellowish distally.
