Descrição da larva de Erythemis mithroides (Brauer) e notas sobre outras larvas conhecidas do gênero (Odonata, Libellulidae)

Abstract

ABSTRACT. DESCRIPTION OF THE LARVA OF ERYTHEMIS MITHROIDES (BRAUER) ANO NOTES ON OTHER KNOWN LARVAEOF THE GENUS (ODONATA, LIBELLULIDAE). The last instar lalVll of Erythemls milhroldes (Brauer, 1900) is described and figured based on exuviae of reared specimens. A comparative analysis ofthis immature stage and the known larvae of the genus are furnished according to the data available in the literature and of specimens of E. credula (Hagen, 1861) and E. veslculosa (Fab., 1775) permiting a diagnose for the larvae of the genus Erythemis Hagen, 1861.

Preliminary dragonfly (Odonata) species list from the Pampa biome in Rio Grande do Sul, Brazil, with ecological notes for 19 new records for the State

“…Ris, 1911 (Libellulidae) This is a tiny libellulid species whose males have bright yellowish colors that make the identification easy in the field. In our survey it occurred only on two locations, which were slow flowing water areas fed by small streams, corroborating the information provided by Costa et al (2001) describing the larvae of the species. It is known to occur in Brazil (Pirassununga, SP), Paraguay and Argentina (Jurzitza 1981, Costa et al 2001).…”

Calvert, 1909 (Libellulidae) A species which is easily identifiable in the field by the yellowish or amber spots on the male wing bases.…”

An updated checklist of Lesser Antillean Odonata

“…This has severely hampered studies in many islands as the literature necessary to identify all known species is scattered and not easily accessible. This is changing, as identification guides have recently been published for the Neotropical region that describe species also occurring in the Lesser Antilles: keys to species for Central America (Förster, 2001), generic keys for adults of Brazilian Zygoptera (Lencioni, 2005(Lencioni, , 2006, generic keys for larvae of Brazilian Odonata (Costa et al, 2004), generic keys for the New World Anisoptera and Zygoptera (Garrison et al, 2006(Garrison et al, , 2010, and generic keys for South American Odonata (von Ellenrieder & Garrison, 2009) as well as the recent publication of a book on the French West Indian Dragonflies (Meurgey & Picard, 2011).…”
