A New Species

Several populations of a partially submerged, robust, morphologically distinct Fossombronia were personally collected in central Mexico and several high elevation subpáramo communities in Venezuela. Comparative morphological studies of these populations with the type collections of F. peruviana, F. herzogii, F. ptychophylla, and F. australis, and a phylogenetic analysis of three chloroplast loci in 18 morphologically defined species of the genus were conducted to determine the taxonomic status of these populations.  Both studies support the recognition of these populations as a new species of Fossombronia, which is named and described herein as Fossombronia delgadilloana. This new species resolves in a clade that is sister to F. peruviana, and is characterized by horizontal, planate, sub-longitudinally inserted leaves, widely dispersed antheridia, with basally expanded stalks, stipitate caulocalyces that lack lamellae, obovoid to ellipsoidal capsules, I-type inner capsule wall thickenings, and spores that are > 40µm, with reticulate distal wall ornamentation. Fossombronia herzogii is recognized as a new synonym of F. peruviana, and a new lectotype is designated for F. ptychophylla.

A New Species

A new species, Pseudodactylaria brevis, is described, illustrated and compared with other Pseudodactylaria and Dactylaria-like taxa. Evidence for the new species is provided by morphological comparison and sequence data analyses. Pseudodactylaria brevis can be distinguished from other Pseudodactylaria and Dactylaria-like species by its short hyaline conidiophores and fusiform, 1-septate hyaline conidia. Phylogenetic analysis of LSU and ITS sequence data was carried out to determine the phylogenetic placement of the species and confirm the taxonomic status of Pseudodactylariaceae.

A New Species

Cryptobenthic fauna investigations are highly relevant at studying biodiversity of regions. Studies of the species composition of Gobiesocidae family were carried out in order to clarify ichthyofauna of different regions, and a new species for the Black Sea coastal zone of Crimea was found. Information about its morphology, biology, behavior and other characteristics is very important because of weak study and indeterminate taxonomic status of this species. As a result of morphological studies of the Crimean specimens no significant difference with the type of the Atlantic-Mediterranean populations has been proven. Naturalization of small-headed clingfish in coastal waters of Crimea has been confirmed and some population characteristics, such as a length-weight relationship, have been described. Peculiarities of habitat which which small-headed clingfish prefers and features of localization, enabling competitiveness have been identified. Identification keys were compiled and are given in the paper.

We describe a new species of a wild Mexican Opuntia producer of edible acidic prickly pears (xoconostles), locally known as “xoconostle de cerro blanco“ (white hillside xoconostle), based on external morphology and micromorphology attributes (mainly characters of the spines). This species is morphologically compared with another four species of wild xoconostles distributed in the same region: O. joconostle, O. leiascheinvariana, O. oligacantha and O. matudae. A taxonomic key for the xoconostles of the area is provided. Based on the phylogenetic analysis of one chloroplast gene, one plastid intergenic spacer and one nuclear molecular marker, the new species was recognized as a monophyletic group within Opuntia s.s. sensu Majure et al.

A New Species

A new species of truffle, T.aztecorum, is described from central Mexico. Tuberaztecorum can be distinguished from other related Tuber species synoptically by a combination of morphological features including ascospore size, pellis cells with irregular thickness, cystidia, ascoma colour and associated host (Abiesreligiosa an endemic Abies species from central Mexico); sequence variation on the ITS rDNA also distinguishes T.aztecorum from related species. A phylogenetic analysis of the ITS rDNA demonstrates that T.aztecorum belongs to the Maculatum clade and is unique from other similar small, white-cream coloured Tuber species distributed in north-eastern Mexico such as T.castilloi and T.guevarai.

Portulaca juliomartinezii is described here as a new species from the Mexican states of Guanajuato and Querétaro. It is a perennial species with fusiform roots, magenta flowers, and a hemispheric operculum, a set of characters that segregate it from other taxa like P. mexicana and P. pilosa. Although the molecular phylogenetic analysis is not clear about the sister relationships of P. juliomartinezii, the new species was found to be member of a high-supported clade within the Pilosa clade.

A New Species

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

Abstract Culex longitubus Somboon, Namgay & Harbach is described as a new species of the Mimeticus Subgroup of the subgenus Culex. The larva is most similar to the larva of Cx. tianpingensis Chen from China, but is distinguished by the length of the siphon and the anal papillae, the form of the comb scales and pecten spines, and the development of setae 7-P, 13-T, 1-X, and 4-X. The adults have wing markings and male genitalia similar to those of species of the Mimeticus Complex. Phylogenetic analysis of COI sequences revealed that the new species is closely related to Cx. murrelli Lien of the Mimulus Complex. The immature stages of the new species were found in stagnant pools and marshes at high altitudes in several districts of Bhutan.

Lines Of Evidence

Abstract The systematics and taxonomy of the broadly distributed bats of the genus Cynomops has changed considerably in the last few years. Among the major changes, Cynomops abrasus was split into two species of large-bodied forms (Cynomops mastivus and C. abrasus) distributed east of the Andes. However, large Colombian specimens identified as C. abrasus from the western side of the Andes had yet to be included in any revisionary work. Phylogenetic analysis performed in this study, using mtDNA sequences (Cytochrome-b), revealed that these Colombian individuals are more closely related to Cynomops greenhalli. Morphological and molecular data allowed us to recognize populations from western Colombia, western Ecuador and northwestern Peru, as members of a new species of Cynomops. Characters that allow for its differentiation from C. greenhalli include a larger forearm, paler but more uniform ventral pelage, more globular braincase, and well-developed zygomatic processes of the maxilla (almost reaching the postorbital constriction). This study serves as another example of the importance of including multiple lines of evidence in the recognition of a new species. Given its rarity and the advanced transformation of its habitat, this new species is particularly important from a conservation perspective.
