Rapid Radiations

Abstract Among mammalian phylogenies, those characterized by rapid radiations are particularly problematic. The New World monkeys (NWMs, Platyrrhini) comprise 3 families and 7 subfamilies, which radiated within a relatively short time period. Accordingly, their phylogenetic relationships are still largely disputed. In the present study, 56 nuclear non-coding loci, including 33 introns (INs) and 23 intergenic regions (IGs), from 20 NWM individuals representing 18 species were used to investigate phylogenetic relationships among families and subfamilies. Of the 56 loci, 43 have not been used in previous NWM phylogenetics. We applied concatenation and coalescence tree-inference methods, and a recently proposed question-specific approach to address NWM phylogeny. Our results indicate incongruence between concatenation and coalescence methods for the IN and IG datasets. However, a consensus was reached with a single tree topology from all analyses of combined INs and IGs as well as all analyses of question-specific loci using both concatenation and coalescence methods, albeit with varying degrees of statistical support. In detail, our results indicated the sister-group relationships between the families Atelidae and Pitheciidae, and between the subfamilies Aotinae and Callithrichinae among Cebidae. Our study provides insights into the disputed phylogenetic relationships among NWM families and subfamilies from the perspective of multiple non-coding loci and various tree-inference approaches. However, the present phylogenetic framework needs further evaluation by adding more independent sequence data and a deeper taxonomic sampling. Overall, our work has important implications for phylogenetic studies dealing with rapid radiations.

Paraleucopidae Wheeler fam. nov. is proposed for the previously unplaced New World genera Paraleucopis Malloch, Mallochianamyia Santos-Neto and Schizostomyia Malloch and undescribed Australian species. A key to genera of Paraleucopidae is provided. Paraleucopis is revised and includes nine species: P. auripes Wheeler & Sinclair sp. nov. (type locality: Andalgala, Argentina); P. bispinosa Wheeler & Sinclair sp. nov. (type locality: Socos, Coquimbo, Chile); P. boharti Wheeler & Sinclair sp. nov. (type locality: Andalgala, Argentina); P. boydensis Steyskal (type locality: nr. Palm Desert, California, USA); P. corvina Malloch (type species of genus; type locality: New Mexico, USA); P. mexicana Steyskal (type locality: Kino Bay, Mexico); P. nigra Wheeler & Sinclair sp. nov. (type locality: Portal, Arizona, USA); P. paraboydensis Wheeler & Sinclair sp. nov. (type locality: Willis Palms Oasis, California, USA); P. saguaro Wheeler & Sinclair sp. nov. (type locality: Usery Mtn Park, Arizona, USA). A key to the species of Paraleucopis is provided. The distribution of Paraleucopis is disjunct, with six species in the western United States and northwestern Mexico and three species in northern Chile and northern Argentina.                The sister group and superfamilial assignment of the Paraleucopidae cannot be established based on current knowledge although the family has affinities to some families of the Asteioinea sensu J.F. McAlpine. A well-supported hypothesis on the relationships of the families of the Acalyptratae will be required before the sister group relationships of Paraleucopidae can be determined.

Abstract Phylogenetic relationships among the Palaearctic genera of the subfamily Simuliinae are analyzed based on the matrix of 100 morphological characters and 37 taxa, including 6 outgroups. Parsimonic analysis was resulted in 3 consensus trees (weighting based on CI, RI and RC indices) of slightly different topology, which show monophyly of the subfamily Simuliinae, tribes Stegopternini, Nevermanniini, Wilhelmiini and Simuliini, and a possible sister-group relationships between the latter two tribes. Tribe Ectemniini is apparently a paraphyletic formation. The analysis also supports transferring of the Stegopternini and Nevermanniini from Prosimuliinae to Simuliinae.

Diplodactylid geckos offer a model system for investigating the biogeographic history of Australia and adaptive radiations in the arid zone, but there is considerable uncertainty in the systematics of several key genera. We used sequence data from mitochondrial DNA to carry out a comprehensive analysis of phylogenetic relationships of geckos in the genus Diplodactylus. Parsimony and Bayesian analyses were highly concordant and allocated all species to one of two monophyletic clades, one comprising the species placed in the vittatus and conspicillatus species groups, the other comprising species placed in the stenodactylus and steindachneri species groups, plus D. byrnei, formerly in the vittatus group. The distinctness of these two clades is supported by external morphology of the digits, body and limb proportions, and osteology of the bones in the orbital region, and we use these characters to formally define the two clades as genera. We revive and expand the genus Lucasium for D. byrnei, D. steindachneri and the stenodactylus group, with the other species staying in a redefined Diplodactylus. The monotypic Rhynchoedura is distinct from Lucasium, although the Bayesian mtDNA analysis (but not parsimony) gives some support for a sister-group relationship between Lucasium and Rhynchoedura. Molecular data suggest that each of these clades represents a distinct radiation into semiarid and arid terrestrial habitats during the mid-Tertiary, well before the hypothesised Pliocene onset of major aridification.

Culicomorpha is a monophyletic group containing most bloodsucking lower dipterans, including many important vectors of pathogens. However, the higher-level phylogenetic relationships within Culicomorpha are largely unresolved, with multiple competing hypotheses based on molecular sequence data. Here we sequenced four nearly complete mitochondrial (mt) genomes representing four culicomorph families, and combined these new data with published mt genomes to reconstruct the phylogenetic relationships of all eight extant culicomorph families. We estimated phylogenies using four datasets and three methods. We also used four-cluster likelihood mapping to study potential incongruent topologies supported by the different datasets and phylogenetic questions generated by the previous studies. The results showed that a clade containing Ceratopogonidae, Thaumaleidae and Simuliidae was the sister group to all other Culicomorpha; in another clade, the Dixidae was basal to the remaining four families; Chaoboridae, Corethrellidae and Culicidae formed a monophyletic group and the Chironomidae was the sister group to this clade; Culicidae and Corethrellidae were sister groups in all trees. Our study provides novel mt genome data in Culicomorpha for three new family representatives, and the resulting mt phylogenomic analysis helps to resolve the phylogeny and taxonomy of Culicomorpha.

Phylogenetic relationships among the families in the infraorder Sejina and the position of Sejina relative to other infraorders of Mesostigmata are re-examined based on molecular and morphological data. Data sets included DNA sequence data for complete 18S, EF-1 , partial CO1genes, and 69 morphological characters. The two families of Heterozerconina consistently group within Sejina, and we propose to synonymize Heterozerconina with Sejina (Sejina s.l). Microgyniina is not the closest relative of Sejina. Rather, Sejina s.l. most often groups with Gamasina. Uropodellidae and Ichthyostomatogasteridae are sister groups and this lineage forms the sister group to Discozerconidae plus Heterozerconidae. Overall, we recognize 5 families within Sejina: Uropodellidae, Ichthyostomatogasteridae, Sejidae, Discozerconidae, and Heterozerconidae.

Stratigraphic Position

Phylogenetic relationships within the neogastropod family Nassariidae are poorly understood as are relationships between the Nassariidae and other fossil and extant buccinid taxa. The poor resolution of nassariid and buccinoidean relationships is due to: 1) the complex distribution among these gastropods of characters commonly used in classification; 2) a number of Mesozoic and Paleogene genera whose relationships to extant buccinoidean lineages are poorly constrained; and 3) a lack of previous efforts to address these problems on a rigorous, phylogenetic basis.The results of a phylogenetic analysis of nassariid genera did not decisively support the monophyly of the family. The buccinid subfamily Photinae was an extant sister group to the Nassariinae in a phylogenetic analysis of extant taxa and on many cladograms from an analysis combining fossil and extant taxa. In addition, Buccitriton (representing the Paleogene Tritiaria group) was a sister taxon to the Nassariinae in all analyses in which it was included, regardless of the identity of the extant nassariine sister group. This suggests that the photines, which likely arose from a Tritiaria ancestor, are the closest living relatives to the Nassariinae. Many Paleogene fossil “buccinoid” taxa appear to be more distantly related to the Nassariinae and possibly to the rest of the nassariids as well. Stratigraphic range data combined with the results of this study suggest that the Nassariinae diversified rapidly in the early Miocene and achieved a cosmopolitan distribution early in their history. A largely Indo-Pacific subclade was consistently deeply-nested within the Nassariinae, suggesting that nassariines invaded the Indo-Pacific region most recently. The timing of this invasion is difficult to estimate but had occurred by the end of the Miocene. Further analyses using molecular sequence data, relative stratigraphic position, or focusing in more detail on the Paleogene taxa are required to resolve the identity of the sister group to the Nassariinae with greater confidence.

New Subgenus

Sarcophaga (Bulbostyla) subgen. nov. is described as a new subgenus of Sarcophaga Meigen to accommodate some species previously assigned to the subgenus S. (Neobellieria) Blanchard. Sarcophaga (Bulbostyla) contains nine species: S. airosalis sp. nov., S. cadyi sp. nov. (type species), S. cuautla sp. nov., S. fattigina sp. nov., S. ironalis sp. nov., S. semimarginalis Hall, S. sternalis (Reinhard), S. subdiscalis Aldrich and S. yorkii Parker. All species are described and illustrated and a key to the species is provided. The species within the subgenus are morphologically uniform externally and are distinguished mostly on male genitalic characters. Phylogenetic relationships within Bulbostyla are unresolved based on morphological characters and will require consideration of additional characters, such as molecular sequence data. The genus-group taxon Robackina Lopes is removed from synonymy with the subgenus Sarcophaga (Neobellieria) and reinstated as a valid subgenus of Sarcophaga (stat. nov.) to accommodate the single New World species Sarcophaga triplasia Wulp. A lectotype is designated for S. triplasia. The subgenus and species are redescribed and illustrated.
