Kumanoa belonging to the order Batrachospermales is the most species-rich and widely distributed genus of freshwater red algae in China. In this study, a new Kumanoa species is described and illustrated from Baiyun Mountain, Guangdong, China, based on morphological observations and phylogenetic analysis. Kumanoa baiyunensis sp. nov is morphologically distinguished from other species by presenting a small habit (0.5–1 cm tall) with abundant branching in upper part of the thallus; carposporophytes spherical and one per whorl; club-shaped trichogynes with distinct stalk; spermatangia sparse and single-grown, terminal on primary fascicles. Phylogenetic analysis based on the concatenated rbcL+COI-5P+UPA alignment places Kumanoa baiyunensis in a well-supported clade (98/0.96, bootstrap proportion/posterior probability) sister to K. faroensis (from USA) and K. spermatiophora (from Hawaii) with high divergence (rbcL: 4.9%–5.0%, COI-5P: 10.1%–10.5%, UPA: 2.3%). In addition, K. baiyunensis can be easily distinguished from ten Kumanoa species reported in China through morphological features such as small thallus size, abundant branching in upper parts of the thallus, and spermatangia sparse, single-grown, and terminal on primary fascicles. The description of this new species expands the diversity of genus Kumanoa in the world.

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.

A New Species

Ants are one of the most successful and widespread organisms in the world. Although ants of the genus Pachycondyla (Hymenoptera: Formicidae: Ponerinae) are predominantly tropical in distribution, Pachycondyla chinensis (Emery) is especially abundant in temperate zones in Asia. Recently, P. chinensis has also become an abundant invasive ant species in the United States. However, it was well-known that the Pachycondyla chinensis species complex remained unresolved. Our molecular and morphological results allow us to distinguish two species in the species complex: the species P. chinensis and the new cryptic species P. nakasujii sp. nov., and these two species are widely and sympatrically distributed and abundant in temperate forests in Japan. Moreover, phylogenetic analysis showed that P. chinensis has been introduced into the United States from Japan. In conclusion, our finding of the new species P. nakasujii suggests that much remains undiscovered even in biologically fascinating and well-studied organisms.

A New Species

A new species of the genus Sabellaria Lamarck, 1818 (Annelida: Polychaeta: Sabellariidae) is described from the intertidal zone of Jeram, Selangor, Malaysia. Sabellaria jeramae n. sp. is a gregarious species that constructs large reefs several hundreds of meters long and 50–200 m wide. The new species is distinguished from other congeners by the character combination of the presence of a single kind of middle paleae with conspicuous morphology, and outer paleae with long frayed teeth. Morphological features of the species are described and compared to those of all congeneric species. We also compare the reef structure and geographical distribution of the new species to those of the members of the family Sabellariidae around the world, demonstrating the ecological traits of the reefs.

Biogeographic Analysis

The mite order Opilioacarida is widely distributed in the tropical and sub-tropical zones of the world, where it is rare and poorly known. On the American continent only two genera, 14 species and one subspecies are known. This work aimed to describe a new species of Caribeacarus from the state of Pará, in the eastern part of the Brazilian Amazon. A phylogenetic analysis of the species in this genus is also presented, and interpreted along with the historical biogeography of this genus in Central and South America. A key to the species of Caribeacarus is provided.

A New Species

Batrachospermum is a widely distributed genus in China. Nonetheless, many taxa recorded previously have no molecular data. In this study, a new species of Batrachospermum called Batrachospermum qujingense is described and illustrated from Qujing, Yunnan, Southwest China, based on morphological observations and a phylogenetic analysis. This species is distinguished morphologically from other species by dioecious thalli, straight carpogonial branches with 7–9 cells and stalked angled obovoid or inflated-clavate trichogynes. In addition, a phylogenetic analysis of the molecular data from the rbcL, COI-5P, and psbA genes indicated separation between the new species proposed in this study and other species in the genus Batrachospermum (4.0–5.3% for rbcL, 7.7%–10.6% for COI-5P, and 2.2–3.2% for psbA ). This is the first species of Batrachospermum reported in Yunnan and the third species of Batrachospermum with molecular data in China. The description of the new species and geographical distribution expands the diversity of freshwater red algae in China.

A New Species

A new species of Kefersteinia (Orchidaceae, Zygopetalinae), K. carolorum, from the state of Táchira, Venezuela, is herein described, illustrated, and characterized based on morphological features. Kefersteinia carolorum is similar to K. lactea from Costa Rica, but it differs in the non-resupinate flowers and the longer callus. The labellum in the upper-most position that distinguishes this species is unique in the genus but has evolved independently in Zygopetalinae at least three times. Evolutionary, ecological, and functional implications of this character are explored. The conservation status of the new taxon is assessed as DD according to IUCN (International Union for Conservation of Nature) criteria. We also provide a key to identify the genera of the Zygopetalinae with labellum in an upper-most position. In addition, we offer a key for the Kefersteinia species from Venezuela, a figure, and a map showing their geographical distributions.

A New Species

Proseriata is a diverse and species-rich taxon of Neoophora (Platyhelminthes). The group is divided into two morphologically well-characterised taxa: Lithophora and Unguiphora. Previous molecular analyses, aimed at ascertaining in-group relationships of the Proseriata, were equivocal in supporting the monophyly of the Lithophora, and of one of its families, the Coelogynoporidae. Here we present a new phylogeny of the Proseriata, based on complete ssrDNA and partial (D1-D6) lsrDNA. The analysis includes 36 proseriate species. 13 new sequences from seven species are used, four of which from species of the Coelogynoporidae and one from a new species of the recently established family Calviriidae. Phylogenetic analysis was performed using Bayesian Inference (BI), maximum likelihood (ML) and maximum parsimony (MP). Clades were considered to have high nodal support if BI posterior probability and ML and MP bootstrap percentages were >90%. The resulting cladogram strongly supports the monophyly of the Lithophora. In addition, the monophyly of the Coelogynoporidae and their inclusion in the Lithophora are corroborated. Within the Lithophora, two sister clades are supported, including Coelogynoporidae+Calviriidae, and Otoplanidae+Archimonocelididae+Monocelididae respectively. In the Coelogynoporidae, there was a poor correspondence between estimates of phylogeny and the monophyly of genera, suggesting the family is in need of systematic revision. Current morphology-based systematic arrangements of Otoplanidae and Monocelididae are not supported by molecular results. The enigmatic taxon Ciliopharyngiella (formerly included in the Rhabdocoela) clusters with the Unguiphora, although with low support. One new species of Coelogynoporidae (Parainvenusta englarorum n. gen n. sp.) is described and discussed in the appendix.
