“…Based on the RMA results for S. platyrhinus (Table III), the elytral length and width did not show allometry. These results showed that all other structures are indicative of sexual dimorphism, as previously suggested by HOLLOWAY (1982) andMERMUDES (2002).…”

“…16), rejecting, at least in this analysis, the hypothesis of size polyphenism in this species. Considering together all the results on allometry and sexual dimorphism, we conclude that, in the case of S. platyrhinus, the dimensions of the rostrum, antennal segments, and ventrites IV and V indicate that sexual dimorphism is in place, as previously suggested by MERMUDES (2002). Traits that exhibited positive allometry are a strong indication of sexual dimorphism (EMLEN 1996, MOCZEK et al 2002, MATSUO 2005, MOCZEK 2006.…”

A recent study of the material housed in the Muséum National d'Histoire Naturelle (Paris, France) provided new information to describe and illustrate the males of Ptychoderes brevis Jordan and Ptychoderes jekeli Mermudes & Napp (Coleoptera; Anthribidae). These males were previously unknown, and their characters had never been studied by the cladistical method. A reanalysis of the genus was carried out, which included 50 characters and 24 taxa (seven as outgroup). The resulting single most-parsimonious cladogram corroborates previous hypotheses of the relationships among the genera of Ptychoderini and groups of Ptychoderes species. The male of P. brevis is characterized by; rostrum 1.5× longer than wide across base; sides not swollen between scrobe and eye; scrobe with a deep narrow extension and a deep distal pit; antennae elongated, reaching middle of elytra; ventrite I swollen, with moderately developed setiferous sex patch, closer to apical margin, clothed with dense yellow pilosity; and ventrite V with lateroapical projections not acuminate. The male of P. jekeli has rostrum slightly longer than wide across base; sides not swollen and the extension shallow; antennae exceeding apical elytron by segment XI; ventrite I with well developed setiferous sex patch, closer to apical margin and with olive green pilosity; and ventrite V strongly impressed, with lateroapical angles not projected and somewhat expanded. The relationship between P. brevis and P. jekeli was confirmed, and this group belongs to the P. crustatus+, corroborating the most basal lineage by the vestiture of the sides of prosternum with a vitta of the same color as the dorsal vestiture, and elytra transversely impressed behind the basal gibbosities.

ABSTRACT. Comparative morphology of three species of Stenocerus (Coleoptera, Anthribidae, Anthribinae). Detailed studies of exoskeleton, mouthparts, wing venation, endosternites, retal plates and male and female terminalia, has been used to improve the systematics and evolutionary studies of the Neotropical anthribids. In this approach S. fulvitarsis (type-species of the genus), S. longulus and S. frontalis were carefully compared including descriptions and illustrations of characters never studied. Among the species examined, S. frontalis display a distinct mimetic pattern with flies of the family Sarcophagidae. The hypothesis that this species does not belong in the genus Stenocerus when compared with the type-species and S. longulus is discussed based mainly on position of the eyes, lack of lateral carinae, lamina of metendosternite longer than arms and median rods of ovipositor narrowed in the proximal region.KEYWORDS. Curculionoidea; Neotropical; Stenocerini; systematics.RESUMO. Morfologia comparada de três espécies de Stenocerus (Coleoptera, Anthribidae, Anthribinae). Estudos detalhados da morfologia do exoesqueleto, peças bucais, venação alar, endosternitos, placas esclerotizadas do intestino posterior e genitálias do macho e da fêmea, foram utilizados para aprimorar a sistemática e evolução de antríbideos neotropicais. Nesta abordagem, S. fulvitarsis (espécie-tipo do gênero), S. longulus e S. frontalis foram minuciosamente comparadas, incluindo as redescrições e ilustrações de caracteres nunca antes estudados. Dentre as espécies analisadas, S. frontalis apresenta um distinto padrão mimético com dípteros da família Sarcophagidae. A hipótese desta espécie não pertencer ao gênero se comparada com a espécie-tipo e S. longulus é discutida com base principalmente na posição dos olhos, ausência de carenas laterais, metendosternito com lâminas laterais mais curtas que os braços e hastes medianas do ovipositor estreitas na porção proximal.
