Aenictus orientalis (Karavaiev)   HNS , n. stat.

Eciton (Aenictus) ceylonicus subsp. orientalis Karavaiev   HNS , 1926: 423 (junior synonym of A. ceylonicus   HNS by Wilson, 1964: 452; new status as valid species).

Aenictus papuanus Donisthorpe   HNS , 1941: 129 (junior synonym of A. ceylonicus   HNS by Wilson, 1964: 452; removed from synonymy with A. ceylonicus   HNS , new synonym of A. orientalis   HNS ).

Aenictus similis Donisthorpe   HNS , 1948: 131 (junior synonym of A. ceylonicus   HNS by Wilson, 1964: 452; removed from synonymy with A. ceylonicus   HNS , new synonym of A. orientalis   HNS ).

Types. Eciton (Aenictus) ceylonicus subsp. orientalis   HNS : Three worker syntypes from Wammar, Aru Island, Indonesia ( ANIC, examined) . Aenictus papuanus   HNS : Two worker syntypes from Malufu, Wharton Range , Papua New Guinea ( MCZC, examined) . Aenictus similis   HNS : Fourteen worker syntypes from Maffin Bay, Irian Jaya , Indonesia (2 in MCZC, examined) .

Comments. In this species the pronotal humeral angles are well developed, causing the anterodorsal surface of the pronotum to be nearly vertical, in dorsal view the area between the humeral angles is weakly convex to weakly concave. This is in contrast to the otherwise similar A. prolixus   HNS and A. turneri   HNS where the humeral angles are weakly developed and the anterodorsal section of the pronotum is gradually sloping, the area between the humeral angles being moderately convex. In addition, A. orientalis   HNS can be separated from A. prolixus   HNS by the shorter scapes (SI 65-82 vs. 89-96) and from A. turneri   HNS by the yellow head and legs which contrast with the yellow-red mesosoma (the body is essentially uniform in colour in A. turneri   HNS ). This species is known from eastern Indonesia and New Guinea.
