Taxonomia de Pseudisobrachium (Hymenoptera, Bethylidae) da Mata Atlântica Brasileira

Epyrini (Epyrinae) are the largest and morphologically most diverse group within Bethylidae. Evans' conception of Epyrini induces misclassification of several taxa and their diagnostic features, such as median lobe of clypeus projected, and fovea in lateroposterior angle of propodeal disc, are insufficient to place species in the tribe. No previous comprehensive cladistic study has recovered Epyrini as a clade, and no synapomorphies are reported for the tribe, suggesting that the group is artificial. We infer a phylogeny based on 391 informative morphological characters for 42 terminal taxa (31 ingroup, 11 outgroup). Monophyly of Epyrini is supported by a petiole with fused root and body as an autapomorphy. Anisepyris Kieffer, Laelius Ashmead, Holepyris Kieffer, Formosiepyris Terayama, Disepyris Kieffer, Bakeriella Kieffer and Trachepyris Kieffer were retrieved as monophyletic. Epyris Westwood and Chlorepyris Kieffer are paraphyletic. The addition of new characters was essential to define Epyrini, and the ventral region of the mesosoma, petiole and male genitalia may help to better understand genera and species limits. All resulting trees indicate that Epyrinae are polyphyletic. Tribes Epyrini and Sclerodermini are revalidated to subfamily status.

“…Groups P and Q correspond to Clade I and II, respectively. Furthermore, Caloapenesia, Calobrachium and Pseudisobrachium show huge gonostipes and unique apically-divided harpe in the subfamily (Azevedo 2008;Gobbi and Azevedo 2010. Pseudisobrachium was recovered to be independent of both Clade I and II in phylogenetic trees.…”

The pristocerine genus Pristepyris comprises 38 valid species recorded worldwide, except in the Australian Region. Of them, three species, namely P. mieae (Terayama, 1995), P. tainanensis (Terayama, 1995) and P. takasago (Terayama, 1996), have been recorded from Taiwan and three species, i.e. P. ishigakiensis (Yasumatsu, 1955), P. minutus (Yasumatsu, 1955) and P. ryukyuensis (Terayama, 1999), from the Ryukyus in Japan. In the present study, the species-level classification of both Taiwanese and Ryukyuan species of Pristepyris was revised using newly-collected specimens by the external and male genital morphological as well as molecular phylogenetic analysis. Overall, six species of Pristepyris were recorded from Taiwan and the Ryukyus. Among these, five were previously recorded for the region and were revised here: P. ishigakiensis, P. mieae, P. ryukyuensis, P. tainanensis and P. zhejiangensis. Additionally, a new species, P. seqalusp. nov., is herein described and illustrated. Furthermore, the species P. minutus is transferred to Eleganesia and P. takasago is synonymized under P. minutus. Due to the new combination of Pristepyris minutus, a key to Taiwanese and Ryukyuan species of the genus Eleganesia, based on male morphology, is provided in Appendix 1. We confirmed for the first time the correspondence between the male and female species of P. zhejiangensis by molecular data. High compatibility in species delimitation patterns, suggested by the morphological and molecular phylogenetic approaches, highlighted the significance of the former approach for accurately classifying aged voucher specimens of Pristocerinae in public collections.

Anatomic glossary of mesopleural structures in Bethylidae (Hymenoptera: Chrysidoidea)

The mesopleuron of Bethylidae has many structures that are used in taxonomic and phylogenetic studies. The lack of understanding of these structures has generated independent terminologies and a series of confusing terms, hampering effective scientific communication. A morphological study and literature review were made in order to solve these problems. Our study resulted in an anatomic glossary with 49 terms that presented a large number of synonyms and polysemies. The glossary standardizes the terms used in the Bethylidae mesopleuron and in other Hymenoptera groups, which will facilitate hypotheses of primary homology in comparative biology.
