Triatoma matsunoi Fernandez-Loayza, 1989 com um estudo sobre a genitália externa masculina (Hemiptera, Reduviidae, Triatominae)

Morphobiological aspects of Rhodnius brethesi Matta, 1919 (Hemiptera:Reduviidae) from the Upper and Middle Negro River, Amazon region of Brazil: I - scanning electron microscopy

“…The first descriptions of the external morphology of R. brethesi using optical microscopy were based on adult specimens (Matta 1919(Matta , 1922. The eggs, nymph stages and life cycle were described by Mascarenhas in 1982Mascarenhas in , 1987Mascarenhas in , and 1990 Other studies related to the external morphology, including in relation to the male and female genitalia, were performed using optical microscopy by Lent (1948), Lent and Jurberg (1969), and Lent and Wygodzinky (1979).Structures like the stridulatory sulcus, buccula and rostrum were highlighted by Carcavallo et al (1996), Silva et al (2003), Ferro et al (1997Ferro et al ( , 1998 Preliminary studies on the external morphology of R. brethesi at an ultrastructural level utilizing scanning electron microscopy have been performed on the structures of the head, thorax and feet of nymphs and adults (Ferro et al 1997, Andrade et al 2002.With aim of obtaining better knowledge of R. brethesi, a morphological analysis was performed on the head (anterior ocular region, ocular-ocellar region, antennae, buccula and rostrum), thorax (stridulatory sulcus) and feet (apex of the tibia, spongy fossette, ctenidium, and tarsus) of adults of this species. …”

Can body traits, other than wings, reflect the flight ability of Triatominae bugs?

“…Females of M. spinolai are invariably wingless, whereas males might be wingless or winged, with wings having normal length or extending up to 2mm beyond the terminalia. The wingless forms need to be METHODS strictly termed micropterous, because tiny wingpads are present both on the meso-and metathoracic segments (13) . Similarly, the two forms of winged males are more correctly described as submacropterous and macropterous because, although the long-winged macropterous forms have similar wing shape and venation to that of other species of Triatominae, the normallength submacropterous wings sometimes show slightly truncated venation of the membrane both of the meso-and metathoracic wings (11) .…”

Rhodnius robustus in Bolivia identified by its wings

“…The only published report of R. pictipes after those of Torrico (Tibayrenc & Le Pont 1984) is probably also a misidentification with R. stali (Dujardin et al 2000). After 1959, R. robustus was reported in the Departments of Pando and Santa Cruz (Wygodzinsky 1959, Lent & Jurberg 1969, Bermudez 1994, Galindez et al 1996, as well as R. prolixus (Lent & Jurberg 1969, Romero & Borda 1979, Borda 1979. No precise geographic origin was described for R. prolixus, which may be considered as a doubtful report (Bermudez 1994), possibly a confusion with R. robustus.…”
