CHECKLIST OF THE SIMULIIDAE OF GUYANA

Crosskey and Howard's world inventory of the Simuliidae (1997) records 13 species of simulids from Guyana: S. cauchense, exiguum s.l., guianense s.l., haematopotum, incrustatum, limbatum, oyapockense s.l., perflavum, perplexum, pulverulentum, quadrifidum, rorotaense, and S. rubrithorax. Since this publication the taxonomy of the species of the Amazon and surroundings has advanced and so the following comments can be made. The records of S. rubrithorax Lutz and S. haematopotum Malloch date back to Smart (1940). Their correct identifications (see Shelley et al. 1997, 2002) are S. maroniense s.l. Floch & Abonnenc and S. oyapockense s.l. Floch & Abonnenc, respectively. Simulium pul-verulentum Knab was based on a record in Vulcano (1981), but Shelley et al. (2002) in their revision of this species discounted its presence in Guyana based on lack of information on specimens and the known distribution of this species. The record for S. incrustatum Lutz refers to the closely related S. limbatum Knab (see Shelley et al. 1997 for morphological diagnoses). The origin of the record of S. exiguum Roubaud cannot be traced, but the present work confirms its presence in the area studied (see Material Examined). Also S. rorotaense should read as S. maroniense s.l. Consequently, prior to the present paper only nine simuliid species had been reliably recorded from Guyana. The 14 species now known from the country are listed in alphabetical order by subgenera and by species within each subgenus. Five species, S. clarki, S. kabanayense, S. lutzianum s.l., S. spinibranchium, and S. subpallidum represent new country records. Species marked with an asterisk bite man.
