A genitália externa na tribo Bolboderini (Hemiptera, Reduviidae, Triatominae)

Abstract

Sete espécies da tribo bolboderini, pertencentes aos gêneros Bolbodera, Belminus, Microtriatoma e Parabelminus, duas das quais já encontradas naturalmente infectadas com Trypanosoma cruzi, foram analisadas e comparadas tendo como enfoque oito estruturas da genitália externa dos machos: Processo mediano do pigóforo (PrP), Processo da conjuntiva (PrCj), Extensão mediana da placa basal (EPIb), Processo do endosoma (PrEn), Suporte do falosoma (SPh), Falosoma (Ph), Processo do gonoporo (PrG) e a Vesica (V). Microtriatoma trinidadensis (lent, 1951) e M. borbai Lent & Wygodzinsky, 1979 mostraram um plano estrutural morfológico semelhante a Parabelminus yurupucu Lent & Wygodzinsky, 1979 e P. carioca Lent, 1943 e deferindo nitidamente de Belminus peruvianus Herrer, Lent & Wygodzinsky, 1954 e B. herreri Lent & Wygodzinsky, 1979 e de Bolbodera scabrosa, Valdés, 1910, não só pela ausência como pela forma de determinadas estruturas. Estas observações comparativas confirmam as afinidades entre Microtriatoma e Parabelminus e suas relações com belminus e Bolbodera.<br>Seven species of the Bolboderini tribe belonging to the genera bolbodera, Belminus, Microtriatoma and Parabelminus, two of them found naturally infected with Trypanosoma cruzi, were analysed and compared emphasizing eight structures of the male external genitalia: median process of pygophore (PrP), conjunctiva process (PrCj), pedicel (EP1b), endosoma process (PrEn), struts (SPh), phallosoma (Ph), medium bridge (PrG) and vesica (V). Microtriatoma trinidadensis (Lent, 1951) and M. borbai Lent & Wygodzinsky, 1979 have shown a structural morphological aspect similar to Parabelminus yurupucu Lent & Wygodzinsky, 1979 and P. carioca Lent, 1943 differing clearly from Belminus peruvianus Herrer, Lent & Wygodzinsky, 1954, B. herreri Lent & Wygodzinsky, 1979 and Bolbodera scabrosa valdés, 1910, not only by the absence but by the shape of some structures. These comparative observations confirm the affinity between Microtriatoma and Parabelminus and their relations with Belminus and Bolbodera

Description of the male genitalia of Belminus rugulosus Stål and Belminus corredori Galvão &amp; Angulo, and comments on the holotype of Parabelminus yurupucu Lent &amp; Wygodzinsky (Hemiptera: Heteroptera: Reduviidae: Triatominae: Bolboderini)

“…Among the taxonomical tools for systematic refinement in Triatominae, studying the male genitalia has been confirmed for this purpose, particularly through several papers from H. Lent and J. Jurberg on this subject (e. g., Lent & Jurberg 1984) (Galvão 2003).…”

“…Lent & Wygodzinsky (1979) commented that the male genitalia of B. peruvianus and B. costaricensis were similar to each other and also to the generic description of Belminus that they furnished. Lent & Jurberg (1984) redescribed the male genitalia of B. peruvianus in greater detail and compared the characteristics of the male genitalia of Bolboderini genera.…”

Belminus ferroae n. sp. from the Colombian north-east, with a key to the species of the genus (Hemiptera: Reduviidae: Triatominae)

“…laportei Lent, Jurberg & Carcavallo, 1995;and B. corredori Galvão & Angulo, 2006. The scarce knowledge of Belminus species is restricted to a few morphological papers (Lent & Wygodzinsky 1979, Lent & Jurberg 1984, Rocha et al 2005. The genus is characterized mainly by the rostrum being very slightly compressed dorsoventrally with its first and second segments elongate, subequal in length, third very short.…”

“…Male genitalia as in generic description (see Herrer et al 1954, Martinez & Carcavallo, 1976, Lent & Wygodzinsky 1979, Lent & Jurberg 1984, Jurberg et al 1999. The general aspect of male genitalia of B. ferroae n. sp.…”
