Vol. 101, No. 1, January & February 1990 35 THE LEPTOCERIDAE (TRICHOPTERA) OF WEST VIRGINIA 1 James B. Glover, Donald C. Tarter 2 ABSTRACT: Over 9,000 adult leptocerids were identified from light trap samples through-out West Virginia. A total of 27 species, including 25 new state records, are reported for West Virginia. The most common species in the state included Cerac/ea cancellata, C. maculata. Oecetis avara, and O. inconspicua. Species that were abundant only in the larger rivers of the western portion of the state included C. /7ava, C. macu/afa, Nectopsyche pavida, and Triaenodes ignitus. Cerac/ea ne/77 was most abundant in the smaller, cooler, fast-flowing streams at the higher elevations in the eastern part of the state. Cerac/ea ophioderus (IL. NC, SC), C. slossonae (FL, GA. PA, VA), and C. wetzeli (MI, PA) were important range extensions into West Virginia. The collection period ranged from 30 April (O. inconspicua and T. ignita) to 17 October (O. c/nerascens). Prior to this study, only two species ofleptocerids had been reported from West Virginia: Oecetis avara (Banks) (Ross, 1944) and Mystacides sepulchralis (Walker) (Yamamoto and Wiggins, 1964). Based on the examination of 9,136 adult leptocerids from black light and Malaise traps, 27 species, including 25 new state records, are recorded from West Virginia. Three important range extensions are noted: Cerac/ea ophioderus (Ross) (IL, NC, SC); C. slossonae (Banks) (FL, GA, PA, VA); and C. wet-zeli (Ross) (MI, PA). The collection period ranged from 30 April, Oecetis inconspicua (Walker) and Triaenodes ignitus (Walker), to 17 October, O. cinerascens (Hagen). The only species that was collected exclusively in the early part of the year (30 April-6 June) was T. ignitus. One male of C. wetzeli was collected on 14 May. Some species had extended flight periods begin-ning in May and extending into September. Detailed collecting data are found in Glover (1988). All adults are stored in the West Virginia Benthological Survey at Marshall Univers-ity. Collecting Stations Collecting stations are listed alphabetically by county (in caps) and each station is assigned a number. The station numbers given below are shown on Figure 1. Stations number 34 and 47 are listed only as county because of incomplete information and are not shown on map. An ^Received December 12, 1988.
