Preliminary Phylogenetic Analysis

AbstractThe subgenus M. (Scaphigenia) Lacordaire includes six species distributed in arid regions of South America. A systematic revision of this subgenus is presented, including re-descriptions and an update of distribution data of the six species. A preliminary cladistic analysis is performed to test the relationships among the species of the subgenus and if the morphological characters used are suitable. A key is presented to separate the seven subgenera of Megalostomis Chevrolat as well as a key for the species of the subgenus M. (Scaphigenia). Male aedeagus internal sac of the nine studied taxa are described and illustrated. This constitutes the first internal sac descriptions for members of this subtribe and could help clarify the homology of such structures within Cryptocephalinae. M. (S) consimilis Achard is reassigned to the species status on the base of genitalic characters. The cladistic analysis was done using forty-one characters from adult external morphology and male and female genitalia. Two species of two different subgenera of Megalostomis: M. (Megalostomis), and M. (Heterostomis) Lacordaire, and one representative of the genus Themesia Lacordaire were selected as out groups. Results were obtained by implicit enumeration using parsimony software. Three equally parsimonious trees were obtained of 45 steps, Ri=0.952, and Ci= 0.941. Support of each group was evaluated by Jacknifing, Bootstrap and Bremer values. Relationships between species are discussed.

Judith River Formation

AbstractMedusaceratops lokiiRyan, Russell, and Hartman, 2010 is an enigmatic taxon of ceratopsid represented by partial parietals from the Mansfield bonebed in the Campanian Judith River Formation, Montana. Originally, all ceratopsid material collected from this bonebed was referred to the centrosaurine ceratopsidAlbertaceratops, but subsequently two parietals were designated the types of the chasmosaurine,M.lokii, in part, because they were interpreted to have three epiparietals bilaterally. Here we describe new material from the bonebed that allows a systematic revision of the taxon. A revised reconstruction of the frill, informed by newly discovered parietals, reveals thatM.lokiihad a broad midline ramus and at least five epiparietals (ep) around the margin of the frill, both traits that are characteristic of Centrosaurinae. From medial to lateral, the epiparietal ornamentation consists of a small, variably procurving epiparietal (ep 1), an anterolaterally curving pachyostotic hook (ep 2), a smaller pachyostoic process (ep 3), and two small triangular epiparietals (ep 4 and 5). A phylogenetic analysis of ceratopsids, which is the first to includeMedusaceratops, indicates thatM.lokiiis a unique, early centrosaurine ceratopsid taxon that is more closely related to Centrosaurini and Pachyrhinosaurini than Nasutoceratopsini. No unequivocal chasmosaurine bones or diagnostic material from any other ceratopsid could be identified from the Mansfield bonebed, suggesting that it represents one of the oldest occurrences of a monodominant accumulation of a centrosaurine ceratopsid on record.

A systematic revision of Mcateella is given including the description of seven new species: M. austera, sp. nov., M. coolgardie, sp. nov., M. esperancensis, sp. nov., M. exocarposa, sp. nov., M. kwoki, sp. nov., M. reidi, sp. nov. and M. schuhi, sp. nov. The following species are redescribed: M. elongata Hacker M. gibber Drake, M. interioris Hacker and M. splendida Drake. Mcateella is defined as a monophyletic group on the basis of clavate guard setae and the stridulatory apparatus. Phylogenetic analysis of the Piesmatidae recognised Eopiesma as the sister-taxon relative to the remaining extant Piesmatidae. The ingroup relationships of Mcateella contained one polytomy. Miespa was found to be the sister taxon to Mcateella, positing a transantarctic relationship. Host plant analysis indicates that Mcateella are not all Acacia specialists as stated in the literature but feed on a wide range of angiosperms.

Thirty-five species are recognized in the Neotropical genus Anopinella Powell, including 5 previously described, A. isodelta (Meyrick), A. triquetra (Walsingham), A. ophiodes (Walsingham), A. aurea (Razowski & Becker), new combination, and A. perblanda (Razowski & Becker), new combination, and 30 described as new: A. albolinea (TL: Costa Rica), A. araguana (TL: Venezuela), A. arenalana (TL: Costa Rica), A. boliviana (TL: Bolivia), A. brasiliana (TL: Brazil), A. cafrosana (TL: Costa Rica), A. cartagoa (TL: Costa Rica), A. carabayana (TL: Peru), A. choko (TL: Colombia), A. cuzco (TL: Peru), A. fana (TL: Venezuela), A. holandia (TL: Guatemala), A. larana (TL: Venezuela), A. macrosema (TL: Costa Rica), A. mariana (TL: Guatemala), A. panamana (TL: Panama), A. parambana (TL: Ecuador), A. peruvensis (TL: Peru), A. phillipsae (TL: Costa Rica), A. porrasa (TL: Costa Rica), A. powelli (TL: Costa Rica), A. rastafariana (TL: Jamaica), A. razowskii (TL: Brazil), A. rica (TL: Costa Rica), A. rigidana (TL: Costa Rica), A. styraxivora (TL: Costa Rica), A. sympatrica (TL: Guatemala), A. tinalandana (TL: Ecuador), A. transecta (TL: Costa Rica), and A. tucki (TL: Peru). The genus occurs from Jamaica and southern Mexico to southern Brazil, Paraguay, and Bolivia. One species has been reared from the fruit of Styrax (Styracaceae), one from a fungus gall on Inga longispina (Fabaceae), and one from the stem of Vernonia (Asteraceae). We re-examine phylogenetic relationships among Anopinella and its putative related genera, Seticosta Razowski, Punctapinella Brown, Strophotina Brown, and Apolychrosis Amsel. We synonymize Ecuadorica Razowski & Becker, 2000, with Anopinella.
