John T. POLHEMUS & Dan A. POLHEMUS University of Colorado Museum, Englewood, U.S.A. & Bishop Museum, Honolulu, U.S.. FOUR NEW GENERA OF MICROVELIINAE (HETEROPTERA) FROM NEW GUINEA Polhemus, J. T. & D. A. Polhemus, 1994. Four new genera of Microveliinae (Heteroptera) from New Guinea. -Tijdschrift voor Entomologie 137: 57-74, figs. 1-30. [ISSN 0040-7496]. Published 15 July 1994. Four new genera of Microveliinae are described from New Guinea. These genera and their con-stituent species are as follows: Tanyvelia gen. n. containing type species T. missim sp. n. from Papua New Guinea; Aegilipsicola gen. n. containing type species A. rapida sp. n. from Papua New Guinea; Tarsovelia gen. n. containing type species T. alta sp. n. from Papua New Guinea, plus T. arfak sp. n. from Irian Jaya, and T. dan i sp. n. from Irian Jaya; and Neusterinsifer gen. n. containing type species N. compacta sp. n. from Papua New Guinea, plus N. sepik sp. n. from Papua New Guinea, N. cyclops sp. n. from Papua New Guinea, N. nabiresp. n. from Irian Jaya, and N. gladius sp. n. from Irian Jaya. Habitus figures of the above new genera are provided, ac-companied by illustrations of the male genital structures and distribution maps for all new spe-cies. Correspondence: Dr Dan A.

The assemblages of Microveliinae occurring on the islands of the Malay Archipelago exhibit a profound shift in taxonomie composition as one progresses from west to east through the region. On the Greater Sunda Islands, Celebes and the Philippines such fau-nas are dominated by members of the genera Pseudovelia Hoberlandt and Microvelia Westwood, accompanied by several other more ecologically spe-cialized and less speciose genera. On New Guinea and surrounding islands, by contrast, Pseudovelia is absent and there occurs instead a group of previously unde-scribed endemic genera which fill the typical Pseudovelia niches. In addition, New Guinea also supports numerous endemic species of in the genus Microvelia sensu lato, but as noted by Andersen (1982) this generic grouping is almost certainly poly-phyletic. A detailed analysis on a world basis of the subgroups contained within it will be necessary be-fore it can be certain that the Papuan and Australian species presently held in Microvelia are in fact conge-neric with the Asian forms. New Guinea thus represents a major center of di-versification for the Microveliinae, with a fauna de-rived independently from that occurring in the Asian tropics. In the present report we describe four new genera of endemic Papuan Microveliinae, all of which are easily separable from Microvelia sensu lato on the basis of distinct apomorphies. The relationships among these genera are still unresolved, however, pending the completion of ongoing revisions of the diverse Australian and New Guinea Microvelia fau-nas. Key to genera of New Guinea Microveliinae 1. Middle tarsi subequal in length to middle tibia (fig. 9); light markings on hemelytra restricted to basal angles; fore femur of male at least slightly modified for phoresy Tarsovelia gen.. n. -Middle tarsi distinctly shorter than middle tibia (figs. 1, 5, 17); light markings on hemelytra may be restricted to basal angles, or may occur also on distal portions; fore femur may or may not be modified for phoresy (figs. 3, 6, 24-26) 2 2. Claws extremely long; light hemelytral markings entirely bright greyish to light bluish pruinose; gula long, rostral cavity demarcated by strongly raised carina Aegilipsicola gen. n. -Claws relatively short; light hemelytral markings not bright pruinose; gula short, rostral cavity not demarcated by strongly raised carina 3 3. Antennae extremely long (fig. 1); comb on fore tibia 3/4 the length of the tibia (fig. 3); only mi-cropterous morph known Tanyvelia gen. n. -Antennae not extremely long (fig. 17); comb on fore tibia less than 3/4 length of tibia (except in Neuterinsifer compacta), if comb on fore tibia 3/4 length of tibia then male proctiger bearing elon-gate process and female abdominal tergites VII 57
