Estudo dos Homiinae (Hymenoptera, Braconidae) em remanescentes de Mata Atlântica Ombrófila do Brasil.
Resumen
In this work the efficiency of three traditional methods of collection of
insects were analyzed and tested (Malaise trap, Moericke trap and "sweepings" of
the vegetation) for studies of the subfamília Hormiinae and, separately, for the six
more abundant sorts in the collections (Allobracon Gahan, 1915; Aspilodemon
Fischer, 1968; Hormius, Nees, 1818; Pambolus Haliday, 1836; Pseudorhysipolis
Scatolini & Penteado-Dias, 2002, and Rhysipolis Förster, 1862). The relation of
this efficiency ea biology of the sorts briefly is argued. The technique of
"sweepings" of the vegetation was the method most efficient for specimen
collection of the majority of the sorts. The theories regarding the distribution of
the species in a latitudinal gradient are argued on the basis of specimen samples of
a subfamily of parasitoid insects, that seem to constitute an exception to the
classic standard of distribution of the largest part of the organisms. The
importance to consider the biology of the organisms and regional variables is
pointed out. The gotten results corroborate with the consulted works and the
hypotheses of geometric limits, energy of the environment and spalling of
resources. Twelve new species and new occurrences for three sorts and two
species for Brazil are cited. The distribution of the species in the points of
collection and the South America is told and illustrated. The potential of new
species is briefly commented with approach in the main sorts and also in the
Northeast Region. Twelve new species of Allobracon Gahan, 1915
(Hymenoptera: Braconidae) are described and illustrated. All species described
were collected in Brazilian Atlantic Forest. A key to species is added.
