A New Species

In recent years, there has been an increase in the descriptions of members of the lizard genus Lepidophyma. Herein, we describe a new species of Lepidophyma from the Huasteca Potosina region of Mexico, previously confused with L. gaigeae, from which it differs in lacking parietal spot, among other characteristics. We inferred its phylogenetic position and provide information on its thermal and hydric physiology, as well as on some other aspects of natural history. Molecular and morphological data supported the independent taxonomic status of the new species, indicating its placement as the sister taxon of L. gaigeae and a wide morphological separation between these species. Lepidophyma lusca sp. nov. has a diurnal-crepuscular activity period and occurs at lower elevations than L. gaigeae. Also, the new species differ from its sister taxon in its physiology, as reflected by its tendency toward higher thermal parameters and water loss rates. With the description of L. lusca sp. nov., the number of species in the genus Lepidophyma rises to 21.

A New Species

A new species in the dicroglossine genus Limnonectes from West Sumatra, Indonesia, is described. Analysis of DNA sequence data from the mitochondrial 12S and 16S gene regions places the species within the Limnonectes kuhlii Complex and demonstrates it to be the sister taxon of Limnonectes kuhlii sensu stricto from Java. Both molecular and morphological data support the recognition of this lineage as a new species. Notably, the presence of a spinule-covered mental plate distinguishes Limnonectes sisikdagu sp. nov. from all other members of the L. kuhlii Complex. Additionally, pair-wise sequence divergence greater than 10% separate the new species from its sister taxon, L. kuhlii from Java.

A New Species

Anopheles (Anopheles) prachongae, a new species of the Gigas Complex from northern Thailand, is described and illustrated in the adult, pupal and larval stages, and bionomics and chaetotaxy tables are provided for the immature stages. The species is distinguished from Anopheles baileyi, the only other species of the complex known to occur in Thailand, and contrasted with other taxa of the complex that occur in the Oriental Region. Available morphological data indicate that An. gigas sumatrana is unique and is therefore formally afforded species status. The three other Sumatran subspecies may be conspecific. The taxonomic status of the non-Sumatran subspecies, i.e. crockeri (Borneo), formosus (Philippines), refutans (Sri Lanka) and simlensis (south-central Asia), is questioned but their status is unchanged pending further study.

Apical Axis

Backgrounds and aims: Hantzschia Grunow is a genus characterized by having valves asymmetric to the apical axis, markedly dorsiventral, with an eccentric raphe on the ventral side supported by fibulae and ‘hantzschioid’ symmetry of the frustules. In 1942 J. Frenguelli published the flora of diatoms of Neuquén province (Argentina), work in which he erected Hantzschia subandina as a new species for science. This work investigates the identity and taxonomic status of this taxon.  M&M: Original material of Hantzschia subandina of the Frenguelli Collection was analysed with light and scanning electron microscopy. Results: Observations on the material suggested two different species were included in the concept of this species assigned originally to the genus Hantzschia. Furthermore, neither of the two species present are assignable to the genus Hantzschia. Nitzschia subandina (Frenguelli) comb. nov. has a large central nodule and a slight asymmetry about the apical axis; it also produces frustules with nitzschioid and hantzschioid symmetry. We designate a lectotype for this taxon. In addition, another diatom in the same material with slight asymmetry about the apical axis has distinctive ornamentation on the mantle of the valve and produces nitzschioid and hantzschioid frustules. For this taxon we tentatively assign it to the non-monophyletic genus Nitzschia, describing it as N. araucana sp. nov. We discuss the possible phylogenetic position of this new taxon, and suggest that the genus Nitzschia is “the next Navicula” ready to be further subdivided into distinct genera.

Original Type

The genus Pedioplanis reaches its northernmost limit in western Angola, where it is represented by three species, Pedioplanis benguelensis, P. haackei and P. huntleyi. The taxonomic status of P. benguelensis remains problematic, mainly due to the vague original description and the loss of the original type material. Here we provide a revision of the Angolan representatives of the genus, with the description of a new species, Pedioplanis serodioi sp. nov., from the lowlands of southwestern Angola. Phylogenetic analyses using a combination of mitochondrial (16S and ND2) and nuclear (RAG-1) markers, as well as morphological data, support the recognition of the new species. For purposes of nomenclatural stability, we designate a neotype for P. benguelensis and provide motivation to correct the spelling of the specific epithet to “benguelensis”. The clarification of the status of P. benguelensis and the description of a new species contribute to a better understanding of the taxonomy and biogeography of the genus Pedioplanis, as well as the general biogeographic context of southwestern Angola, adding to the growing evidence in favor of the recognition of this region as a hotspot of lizard diversity and endemism. An updated key to the genus is also provided.

Silene sunhangii, a new species of Caryophyllaceae known from only three populations in Hubei and Hunan provinces of central China, is described. Both morphological and molecular data were used to assess the taxonomic status and relationships of this species. Morphologically, S. sunhangii is most similar to S. platyphylla Franch. from which it differs most readily in having 3-veined elliptical leaves without pubescence, tasseled catacorolla, pale purple to red petals without a linear lobe or narrow tooth and lanceolate, bifid to one third. A phylogenetic analysis based on nuclear ITS region identified the new species as a well-supported, independent lineage. Our new species is nested within a grade that encompasses species representing a polyphyletic Silene sect. Physolychnis (Benth.) Bocquet. Both the genetic and morphological data support the recognition of Silene sunhangii as a distinct species, although there is inconsistency between these two datasets as to the relationships of the new species.

Benthic marine heterocytous cyanoprokaryotes of Mexico´s tropical coast are being recognized as an important and conspicuous component of the supralittoral and intertidal zones usually described as an extreme and low diversity biotope. Although Kyrtuthrix has been reported from different coasts worldwide, its complex morphology has led to differing taxonomic interpretations and positioning. Ten marine supra and intertidal populations of Kyrtuthrix were analyzed using a detailed morphological approach, complemented with ecological and geographical information as well as DNA sequence data of the 16S rRNA gene and associated 16S–23S ITS. Kyrtuthrix huatulcensis is described as a new species, different from K. dalmatica Ercegovic and K. maculans (Gomont) Umezaki based primarily on morphological data. Our material has smaller dimensions in thalli, filaments, trichomes and cells, and possesses differences in qualitative characters as well. Our material is epilithic as in K. maculans but not endolithic as in K. dalmatica. The analysis of molecular data, mainly 16S rRNA gene sequence, show that this genus is within the Rivulariaceae clade, and outside of the Scytonemataceae clade. ITS secondary structure comparison with some of the closer representatives of Rivulariaceae shows considerable differences with these related genera. Based on the evidence gathered in this study, inclusion of Kyrtuthrix within the Rivulariaceae, rather than the Scytonemataceae, is fully supported.

Multiple collections of a new member of the Entolomataceae were found in W National Park of Niger during a survey of macrofungi. This new species with a dark reddish brown scaly pileus surface and a yellow stipe belongs in the genus Rhodophana of the Rhodocybe-Clitopilus clade in the Entolomataceae. Using a three-gene analysis of the phylogenetic position of Rhodophana flavipes it is most closely related to the recently described Rhodophana squamulosa from India and is a sister taxon to Rhodophana nitellina and R. melleopallens. Micromorphological examination of the type of Rhodocybe fibulata, another African species with a scaly cap, confirms that it belongs in Rhodophana, thus a new combination Rhodophana fibulata is proposed.

Abstract. This study presents a revision, using type material, of the tiny foraminifera Discorbina minutissima Chaster, D. chasteri Heron-Allen &amp; Earland (erected as a nomen novum for D. minutissima Chaster, non Seguenza) and D. chasteri var. bispinosa Heron-Allen &amp; Earland. All are referred to the genus Rotaliella Grell. Heron-Allen &amp; Earland’s new name chasteri is shown to be only applicable as a replacement name for Chaster’s species; their own material from Clare Island is a new species, named here R. heronalleni sp.nov. In addition, two other species — Rotaliella ? simplex (Sidebottom) and R. antarctica sp.nov. — have been recognised amongst the specimens labelled as D. chasteri in the Heron-Allen &amp; Earland Collection in the Natural History Museum (BMNH). Lectotypes are designated for Rotaliella chasteri and R. bispinosa.

A New Species

The genus Linum consists of 15 species in Iran. A new species as well as a new record from Iran is described and illustrated here as L. khorassanicum and L. turcomanicum, respectively. The original description of the latter species is incomplete and ambiguous, probably due to incomplete taxon sampling. In this work, after a comprehensive taxon sampling from the entire distribution range of the species in northeast of Iran, the taxonomic description of L. turcomanicum is completed. The present study considers morphological and molecular (the nrITS region) analyses of the both species. In phylogenetic analysis based on the molecular data, we included these species and some related Linum species to examine the phylogenetic relationship of the new species and L. turcomanicum with other members of the genus. Linum turcomanicum is morphologically almost similar to L. austriacum and L. perenne, but it can be distinguished from them on the basis of several traits such as fruiting-pedicel form and length of petal. Likewise, results obtained from the molecular phylogenetic tree are consistent with those obtained from the morphological data. Linum khorassanicum is well characterized morphologically by having erect fruiting pedicels and inflorescence with few flowers. Our results suggest that the morphological data are in agreement with the molecular phylogenetic tree in which the taxonomic status of L. khorassanicum is confirmed as a new species. Based on IUCN Red List categories and criteria, L. khorassanicum and L. turcomanicum are evaluated as Endangered and Near Threatened species, respectively.
