Neoprincipia nov. gen., a new Mississippian red alga, and remarks on the Archaeolithophyllaceae (Rhodophyta)

A new alga is described from the late Visean of SW Spain: Neoprincipia nov. gen. Specimens of this new genus were either usually assigned to Archaeolithophyllum or Principia of Brigantian-Serpukhovian age. Two new species N. guadiatica nov. gen., nov. sp. and N. tethysiana nov. gen., nov. sp. are described. Their massive appearance, in continuous series, characterizes the base of the Brigantian elsewhere in the Paleotethys, although some rare cases of first appearance in the late Asbian exist. Its acme is Brigantian, but it extends into the Pendleian. The genus Neoprincipia, and its family Archaeolithophyllaceae, are interpreted to be the earliest true red algae, that exhibit clearly differentiated hypothallus and perithallus, and therefore are situated at the origin of these “coralline algae”, which are very prolific from the Cretaceous to the Recent.     

Four new species of Chimarra Stephens (Trichoptera: Philopotamoidea: Philopotamidae) from Indian Himalaya

Four new species are added to the philopotamid fauna of India. The newly described species under Chimarra Stephens are Chimarra barnardi sp. nov. and C. padami sp. nov. (both from Arunachal Pradesh), C. bidenta sp. nov. from Uttarakhand and C. quadrata sp. nov. from Sikkim. These species are distinguishable from each other as well as from previously known allied species by consistent variation in the structure of inferior appendages, tergite X and the phallic apparatus of males.     

On the Cyprideis species flock (Crustacea, Ostracoda) in Lake Tanganyika, with the description of four new species

Four new species, belonging to three genera, of ostracods from Lake Tanganyika are described: Mesocyprideis nitida sp.nov., Romecytheridea belone sp.nov., R. plegma sp. nov. and Cyprideis loricata sp. nov. The Cyprideis species flock of Lake Tanganyika now consists of 17 formally described species (16 endemic) in 6 genera (4 endemic). The geographical and ecological distribution of the four species is briefly discussed and some supplementary remarks on the radiation of the Cyprideis species flock in Lake Tanganyika are offered.     

Middle Permian Ostracods from Tak Fa Limestone, Phetchabun Province, Central Thailand

This paper presents the first Permian ostracod fauna discovered in Thailand. The ostracods are recovered from the Tak Fa Limestone (Middle Permian) in Phetchabun province, central Thailand. The ostracods belong to eight genera and 15 species. Four species are newly described: Sargentina phetchabunensis nov. sp., Geffenina bungsamphanensis nov. sp., Reviya subsompongensis nov. sp. and Bairdia takfaensis nov. sp. The ostracod assemblages characterize a shallow marine, near shore environment at the time of deposition. Except for one species, which shows palaeobiogeographical links between Central Thailand and South China, all the other species are endemic.     

Integrative Taxonomy and Species Delimitation in Harvestmen: A Revision of the Western North American Genus Sclerobunus (Opiliones: Laniatores: Travunioidea)

Alpha taxonomy, and specifically the delimitation of species, is becoming increasingly objective and integrative. The use of coalescent-based methods applied to genetic data is providing new tools for the discovery and delimitation of species. Here, we use an integrative approach via a combination of discovery-based multivariate morphological analyses to detect potential new species. These potential species are then used as a priori species in hypothesis-driven validation analyses with genetic data. This research focuses on the harvestmen genus Sclerobunus found throughout the mountainous regions of western North America. Based on our analyses, we conduct a revision of Sclerobunus resulting in synonymy of Cyptobunus with Sclerobunus including transfer of S. cavicolens comb. nov. and elevation of both subspecies of S. ungulatus: S. ungulatus comb. nov. and S. madhousensis comb. nov., stat. nov. The three subspecies of S. robustus are elevated, S. robustus, S. glorietus stat. nov., and S. idahoensis stat. nov. Additionally, five new species of Sclerobunus are described from New Mexico and Colorado, including S. jemez sp. nov., S. klomax sp. nov., S. skywalkeri sp. nov., S. speoventus sp. nov., and S. steinmanni sp. nov. Several of the newly described species are single-cave endemics, and our findings suggest that further exploration of western North American cave habitats will likely yield additional new species.

Morphological and Molecular Diversity of the Neglected Genus Rhizomastix Alexeieff, 1911 (Amoebozoa: Archamoebae) with Description of Five New Species

The genus Rhizomastix is a poorly known group of amoeboid heterotrophic flagellates living as intestinal commensals of insects, amphibians or reptiles, and as inhabitants of organic freshwater sediments. Eleven Rhizomastix species have been described so far, but DNA sequences from only a single species have been published. Recently, phylogenetic analyses confirmed a previous hypothesis that the genus belongs to the Archamoebae; however, its exact position therein remains unclear. In this study we cultured nine strains of Rhizomastix, both endobiotic and free‐living. According to their light‐microscopic morphology and SSU rRNA and actin gene analyses, the strains represent five species, of which four are newly described here: R. bicoronata sp. nov., R. elongata sp. nov., R. vacuolata sp. nov. and R. varia sp. nov. In addition, R. tipulae sp. nov., living in the intestine of crane flies, is separated from the type species, R. gracilis. We also examined the ultrastructure of R. elongata sp. nov., which revealed that it is more complicated than the previously described R. libera. Our data show that either the endobiotic lifestyle of some Rhizomastix species has arisen independently from other endobiotic archamoebae, or the free‐living members of this genus represent a secondary switch from the endobiotic lifestyle.
