A new Leioproctus with unique wing venation in males (Hymenoptera: Colletidae: Paracolletinae) with comments on unusual wing modifications in bees

Leioproctus idiotropoptera Packer, new species, is described on the basis of one male and two females from the Northern Territory, Australia. The male has modifications of the venation and setation of the forewing that are unparalleled among the bees and also possesses highly modified mandibles and fore- and midlegs. The new species does not fall easily into any of the presently named subgenera of Leioproctus, but, given the great need for revision of this group, an additional subgeneric name is not presented at this time. Some comments on unusual wing modifications in bees are made.
