Análise cladística da tribo Rhopalophorini Blanchard, 1845 (Coleoptera, Cerambycidae)

Abstract

ABSTRACT. Cladistic analysis of the tribe Rhopalophorini Blanchard, 1845 (Coleoptera, Cerambycidae). Rhopalophorini is primarily a New World group. Of the 23 known genera, 19 were described from the Neotropical region. A cladistic analysis of the American genera was carried out with 91 morphological characters. The genera Ozodes Audinet-Serville and Lissozodes Bates, recently transferred to Necydalopsini, were included in the analysis in order to investigate their relationships with the Rhopalophorini. The results suggested that their shared similarities with the Rhopalophorini are symplesiomorphies at the level considered in the analysis, so they are maintained in Necydalopsini, and Neozodes Zajciw, indicated as the sister group of Ozodes, is herein transferred to this tribe. In the same way, Elaphopsis Audinet-Serville is transferred to Ibidionini. Rhopalophorini, as defined in the present work, is a monophyletic group and includes 17 American genera. Within Rhopalophorini, Argyrodines + Parozodes constitute the basalmost group, and Cycnoderus is the sister group of the two major clades formed, one by Ischionodonta, Disaulax, Cosmisoma, Closteropus and Gurubira, and the other, by Rhopalophora, Coremia, Merocoremia, Dirocoremia, Thalusia and Lathusia; the relationships of Rhopalophorella, Rhopalina and Muxbalia remain inconclusive. A phylogenetic classification of Rhopalophorini at the genus level is proposed.

Comparative morphological study of the Neotropical Cleomenini genera and their transference to the tribes Rhopalophorini Blanchard and Rhinotragini Thomson (Coleoptera, Cerambycidae, Cerambycinae)

“…Similarly, the intercoxal process of the prosternum (Figs. 31-34) is like that observed in Rhopalophorini (MARQUES & NAPP 2003) and much different from the intercoxal process of Cleomenes (Fig. 37) which is very narrow and subparallelsided, suddenly enlarged at the apex.…”

“…Finally, MARQUES & NAPP (2003), in the cladistic analysis of the Rhopalophorini, raised the hypothesis that the Neotropical Cleomenini genera may belong to that tribe.…”

“…It is, however, more similar to the latter by the elongate genae and eyes with transverse lower lobes with the upper margins and the portion linking the eye lobes distant from the antennal tubercles. The latter two conditions have been considered synapomorphies of Rhopalophorini (MARQUES & NAPP 2003). In Cleomenes (Fig.…”

“…The cylindrical galea, as long as the palp, enlarged apically and obliquely truncate is a synapomorphy of Rhopalophorini (MARQUES & NAPP 2003). However, Listroptera, Aguassay, Haenkea, Dihammaphora, Timabiara and Dihammaphoroides may be distinguished from both Cleomenes (Fig.…”

“…However, the quadrangular mentum as occurring in Rhopalophora and in the Neotropical Cleomenini, was considered as a synapomorphy of the Rhopalophorini (MARQUES & NAPP 2003), differing from Cleomenes that has a transverse mentum. Pandrosos differs by the deep, angulate median notch of the ligula and Dihammaphoroides by the general shape of this structure.…”
