Paulo, vol. 25(12) :99-103 30-IX-1971 NOTES ON THE GENUS CORDYLIGASTER MACQUART, WITH THE DESCRIPTION OF A NEW SPECIES FROM BRAZIL (DIPTERA, TACHINIDAE) J. H. Guimarães Abstract Cordyligaster townsendi, sp. n. iholotype male from Mato Grosso, Pôsto Garapu, Rio 7 de Setembro), is described. TMs fly is dose to C. analis Macquart, differing chiefly in details of body coloration. Keys and notes on the distribution, biology and systematics of the genus are pre- sented. Through the activities of the "Expedição Permanente da Amazô- nia", sponsored by the Fundação de Amparo à Pesquisa do Estado de São Paulo, the Museu de Zoologia da Universidade de São Paulo, and the Museu Paraense "Emílio Goeldi", a number of specimens of Cor- dyligaster Macquart have been collected. In a recent attempt to identify the specimens in the collection of the Museu de Zoologia, a new species was found. Biological observations Townsend (1936: 52), while collecting at Boa Vista, about 100 miles up the River Tapajós, Pará, Brazil, recorded that "hundreds of females [of Cordyligaster petiolatus W.], unaccompanied by males, occurred pn the veranda screens of the laboratory from the last week in August to the first week in October and ali examined contained developed maggots in the uterus. It is certain that these flies had not issued from hosts in or around the laboratory, for in such case males should have been present and the females should not have uni- formly contained fully developed maggots". Townsend concluded in his report that wasps or hornets should be the hosts of Cordyligaster, as these Hymenoptera were very abund- ant in that region. This biological relationship with wasps, as sus- pected by Townsend, has not yet been established through rearing. Museu de Zoologia, Universidade de São Paulo.

Aldrich (1927) revised this group, recognizing three species for Cordyligaster, and two for Eucordyligaster. Both genera are neotro- pical in distribution. except for EucordyligaMer ( which has a wide northern range, reaching the eastern United btates (Pennsylvania and Maryland). Key to genera 1.

Eucordylidexia ategulata Townsend, 1915: 41 (Type-locality: Guatemala, Puerto Barrios). This species is readily recognizable by the black antennae, palpi and lees Originally described from Brazil, it has been reported from Rolivia Costa Rica, and Guatemala. In South America this species nresents a curious disjunct distribution — in our collection there are specimens from the Brazilian northern States (Pará, Amazonas, and Vol. 25 (12), 1971 101 Maranhão), and from Argentina (Tucumán). No specimen has been recorded between those areas, and dose examination of both samples did not reveal any morphological character suggesting the possibility of the existence of two distinct species.

Unreoognized species Cordyligaster analis (Macquart) Megistogaster analis Macquart, 1851: 187 (1851: 214) (Type-locality: Brazil, Amazonas). Cordyligaster analis; Townsend, 1917: 122; Aldrich, 1927: 85. This species, described from a single male from the Amazon, is not represented in our collection, and its identity is not yet clear. Aldrich (Z. c.) stated that the type had the fourth segment of the abdômen black, except on its anterior border; he also identified as this species a specimen from the Guyana in the Melander collection (now in the U. S. National Museum), with the fourth abdominal segment wholly yellow, as well as the legs and coxae. According to Dr. R. Crosskey (unpu- blished notes on the type-material of Macquart and Robineau-Desvoidy), the Paris Museum contains no types of Cordyligaster.
