New Species Records for the Blackfly (Diptera-Simuliidae) Fauna of Argentina with Description of Adults, Pupa and Larva of Simulium oyapockense s. l. and S. seriatum
Two blackfly species Simulium (Cerqueirellum) oyapockense Floch &
Abonnenc and S. (Hemicnetha) seriatum Knab are recorded from Argentina,
representing the most southern register for both species. S.
oyapockense is a species epidemiologically very important, as a vector
of onchocerciasis in the Amazonian focus. Both species are described
and illustrated and their distribution are reported, in similarity to
others like S. roraimense Nunes de Mello and S. ganalesense Vargas et
al. in reference to S. oyapockense and S. mexicanum Bellardi similar to
S. seriatum are discussed
The preimaginal stages of Cryptotylus unicolor (Wiedemann) and Tabanus nebulosus ornativentris Kroeber (Tabanidae-Diptera-Insecta)
A larva with peculiar very long pubescence on the integument, the pupa
of Cryptotylus unicolor, and the larva and pupa of Tabanus nebulosus
ornativentris are described and illustrated
Description of Male, Larva and Pupa of Stibasoma theotaenia (Wiedemann) (Diptera-Tabanidae)
Unknown male, larva and pupa of Stibasoma theotaenia from northern
Argentina are described and illustrated. Larvae were collected from
terrestrial Bromeliaceae of Aechnea sp. and maintained in the
laboratory through development
The Polytene Chromosomes of Cnesia dissimilis (Edwards) and Three Species of Gigantodax Enderlein (Diptera: Simuliidae) from Lanin National Park (Argentina)
Cytological studies were made on larvae of Gigantodax marginalis, G. chilensis, G. fulvescens and Cnesia dissimilis from four creeks in Lanin National Park, Neuquen province, Argentina. Chromosome maps and idiograms of these species are presented. The following inversions were observed: G. marginalis: IL-1 (X-linked inversion), IL-2 (Y-linked inversion), IIS-1.2, IIL-1, IIIL-4,5; G. chilensis: IL-4 (X-linked inversion), IIS-1.2, IIIL-4,5; G. fulvescens:IL-1 (X-linked inversion), IL-3 (Y-linked inversion), IIS-1.2, IIL-1, IIIL-4,5; C. dissimilis: IL-1, IL-5, IIIL-1. Karyological information was used to construct a cladogram and Cnesia sp. Was found to show close resemblance to the three Gigantodax spp
