A NEW SPECIES OF BRACHYCENTRUS FROM GEORGIA WITH TWO UNUSUAL LARVEL CHARACTERS (TRICHOPTERA: BRACHYCENTRIDAE) 1 J. B. Wallace 2 In several vials of Trichoptera larvae sent to the University of Georgia by Dr. W. L. Peters of Florida A & M University, there were some larvae of an unusual brachycentrid that Dr. Peters had collected from the Etowah River in north central Georgia. These larvae have several characters that would place them near the western genus Oligoplectrum in Wiggins, (1965) key to the genera of North Ameri-can Brachycentridae larvae. Several visits to the area where the larvae were first found resulted in association of all life stages. The adults proved to be a new species of Brachijcentrus near B. numerosus (Say). The following is an account of the taxonomy and biology of this new species. Brachycentrus etowahensis NEW SPECIES MALE. Length=8-10 mm; dark brown to black. Antennae about same length as body. Maxillary palps 3 segmented and curved upward over face, basal segment short and somewhat globular, palps with long, dense white setae occasionally intermixed with a few scattered, black setae near base of palps. Last two segments of labial palps distinctly lighter in color than basal segment. Tibia and tarsi of all legs light, femora dark. Tibial spurs 2, 3, 3. Wings pale brown with venation as in Figs. 7 and 8. Seventh abdominal sternite produced into a rather wide posterioventral plate that is generally broader than long ( Fig. 5). Genitalia as in Fig. 1. Ninth segment narrowed dorsally. Cerci somewhat variable, generally ovate, often somewhat pointed ventro-apically, and separated 'This research was supported by grant 18050 DFQ from the FWQA-EPA.
