In response to Quinn (Biol Philos, 2017. 10.1007/s10539-017-9577-z) we identify cladistics to be about natural classifications and their discovery and thereby propose to add an eighth cladistic definition to Quinn's list, namely the systematist who seeks to discover natural classifications, regardless of their affiliation, theoretical or methodological justifications.

Our understanding of primate evolution is ultimately based on patterns of phyletic relationship and morphological change documented in the fossil record. Stratophenetic interpretation of living and fossil primates yields an objective alternative to the arbitrary scala naturae assumed implicitly in traditional comparative biology. Fossils provide an outline of primate history constraining compar...

The Nimravidae is a family of extinct carnivores commonly referred to as "false saber-tooth cats." Since their initial discovery, they have prompted difficulty in taxonomic assignments and number of valid species. Past revisions have only examined a handful of genera, while recent advances in cladistic and morphometric analyses have granted us additional avenues to answering questions regarding...

The monotypic linyphiid genus Lomaita Bryant 1948 is redescribed. We present an updated description of the male of L. darlingtoni, the first description of the female and data on its natural history and distribution in the Dominican Republic. We provide a hypothesis on the phylogenetic placement of Lomaita based on cladistic analyses of morphological characters.

A cladistic analysis of the genera of the Macrothricidae (Crustacea, Cladocera, Radopoda) was performed based on 36 morphological characters, and including 15 terminal taxa (three as outgroups). The single tree obtained from this analysis supported the monophyly of Macrothricidae and Macrothricinae. The group called as “non-Macrothricinae” was indicated as paraphyletic. Neothricidae was also no...

In the present study, Collartida eowilsoni sp. nov. is described from Guadalcanal (Solomon Islands), which extends distribution of genus and tribe Collartidini as a whole to Oceanian biogeographic realm. The highly aberrant morphology new species required reassessment diagnostic characters generic limits Collartida. To evaluate systematic position C. morphology-based cladistic analysis was perf...
