Two New Species

In northwestern Victoria, Australia, the Pterostylis (Orchidaceae) section Oligochaetochilus ‘rufa group’ comprises several little studied and poorly collected taxa. We surveyed populations of the rufa group in the Sunset Country, collecting information on the habitat and vegetation community. Fourteen sites were surveyed for plants with affinities to P. biseta and P. exelsa. We measured 23 morphological traits for each of 31 field-collected and seven herbarium specimens from this area. Multivariate analyses were undertaken, with cluster analysis and ordination performed on range-standardised data. Three distinct groups were present in both an ordination and dendrogram, with key diagnostic characters relating to the labellum. These groups were compared against other morphologically similar species of Pterostylis. Our analyses confirmed one of these groups as P. biseta, which is widespread in northwestern Victoria, and two as previously undescribed, putatively rare taxa, described here.

Two New Species

Dima guizhouensis Ruan, Kundrata & Qiu sp. nov. and Dima xiaolongi Ruan, Kundrata & Qiu sp. nov. are described from Guizhou and Hunan Provinces in China, respectively. Both species are easily distinguishable from most of their congeners by having a strongly convex pronotum and relatively long elytra with carinate interstria VI. The only superficially similar species is D. tianmuensis Qiu & Kundrata in Qiu et al. (2018) from Zhejiang Province. Habitus and main diagnostic characters are figured for both new species, and their systematic placement is discussed. The discovery of these species brings the total number of Dima species in China to 13.

The pseudoscorpion sample from a cave in Bosnia has been studied. Two new species have been described herein: Chthonius (Chthonius) protobosniacus n. sp. and C. (C.) kladanjensis n. sp. Both taxa are considered endemic of Bosnia and the Balkan Peninsula. In this paper, diagnostic characters of the analyzed forms are thoroughly described and figured. Taxonomic interrelationship amd geographic distribution are briefly discussed.

Passalus Fabricius, 1792 is the largest genus of Passalidae and presents great diversity in South America, mainly in the Amazon region. Currently this complex and heterogeneous genus is subdivided into three subgenera: P. (Pertinax) Kaup, 1869, P. (Mitrorhinus) Kaup, 1871, and P. (Passalus). Herein, two new species of Passalus from the western region of the Brazilian Amazon, a diverse but poorly studied area, are described and illustrated. The new species Passalus (Pertinax) deuterocerus sp. nov. and Passalus (Passalus) cleidecostae sp. nov. are compared with similar species occurring in nearby regions. Also, the diagnostic characters used to define the subgenera and sections of Passalus are summarized.

Myxosporean Species

SUMMARYOur survey of marine fish from South Africa and Indonesia revealed the presence of two new myxosporean species of the genus Sphaeromyxa for which we provide morphological and sequence data. Sphaeromyxa clini n. sp. detected in three Clinus spp. and Muraenoclinus dorsalis from South Africa is morphologically similar to Sphaeromyxa noblei previously described from Heteroclinus whiteleggii from Australia and to several other sphaeromyxids with arcuate spores and rounded ends. This similarity is reflected by phylogenetic positioning of S. clini n. sp. which clusters within the ‘incurvata’ group of the Sphaeromyxa clade. It differs from morphologically similar species by spore and polar capsule dimensions, host specificity and geographic distribution. Sphaeromyxa limocapitis n. sp., described from Gephyroberyx darwinii from Java, is morphologically similar to sphaeromyxids with straight spores and to marine Myxidium species with spindle-shaped spores but differs from them by spore and polar capsule dimensions, host specificity and geographic distribution. S. limocapitis n. sp. represents a separate lineage of the Sphaeromyxa clade and appears to be a missing link in the evolution of sphaeromyxids.

Formerly Cnemidophorus was thought to be the most speciose genus of Teiidae. This genus comprised four morphological groups that were later defined as four different genera, Ameivula, Aurivela, Cnemidophorus and Contomastix. The last appears as paraphyletic in a recent phylogenetic reconstruction based on morphology, but monophyletic in a reconstruction using molecular characters. Six species are allocated to Contomastix. One of them, C. lacertoides, having an extensive and disjunct geographic distribution in Argentina, Uruguay and Brazil. Preliminary analyses revealed morphological differences among its populations, suggesting that it is actually a complex of species. Here, we describe a new species corresponding to the Argentinian populations hitherto regarded as C. lacertoides, by integrating morphological and molecular evidence. Furthermore, we demonstrate that the presence of notched proximal margin of the tongue is a character that defines the genus Contomastix.

Abstract—Two new diploid species, Aira minoricensis and Aira hercynica, are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.
