Two new species of the genus Exocelina Broun, 1886: E. athesphatossp. nov. and E. tsingasp. nov. are described from New Guinea and placed into the E. ekari group based on the structure of their male genitalia. The two species are very similar with respect to their external morphology and characterised by almost identical, strongly modified male antennae. However, they can easily be separated by the shape and setation of the median lobe and paramere. Based on morphological similarity and results of a molecular phylogenetic analysis, we suggest these are sister species. Both of them have been collected on the southern slopes of the Central Range (the spine of New Guinea), with a distance of ca. 380 km straight line between the collecting localities.

Two New Species

The genus Anisoderomorpha Arrow, 1925 (Coleoptera: Erotylidae: Languriinae) is redescribed and two new species of Anisoderomorpha are described: A. tamdaoensis sp. nov. from Vietnam and A. malayana sp. nov. from Malaysia. The adults of A. tamdaoensis sp. nov. were found to be sexually dimorphic in external morphology, particularly in the shape of the head and mandibles: females have a large asymmetrical head and mandibles, whereas males have a symmetrical head with slightly asymmetrical mandibles. All three members of Anisoderomorpha and its related taxon, Celolanguria curvipes Arrow, 1925, are illustrated and the host plant of Anisoderomorpha is predicted based on the morphological similarity of the specified mouthparts to those of other genera.

The laniatorean family Phalangodidae has been largely reduced to a core of Holarctic species; however, many taxa were never formally transferred to other families. We examined a group of harvestmen related to Beloniscus Thorell, 1891, from South-east Asia and determined the nature of the relationships of the ‘Beloniscus-like harvestmen’, herein described as the new family Beloniscidae, fam. nov., in the broad context of Laniatores. Based on a molecular phylogenetic analysis of a broad representative laniatorean Sanger-sequences dataset we found support for our taxonomic hypotheses that (1) inclusion of Beloniscidae, fam. nov. in Phalangodidae would render the family non-monophyletic, and (2) Beloniscidae, fam. nov. represents a lineage that is morphologically and genetically distinct from all other known laniatorean families. The new family Beloniscidae is endemic to South-east Asia and comprises 37 species in two new subfamilies: Beloniscinae, subfam. nov. and Buparinae, subfam. nov. Beloniscinae includes the genera Beloniscellus Roewer, 1931, Beloniscops Roewer, 1949, Belonisculus Roewer, 1923, Beloniscus (type genus) and Kendengus Roewer, 1949. Buparinae includes the genera Buparellus Roewer, 1949, Bupares Thorell, 1889 (type genus) and Buparomma Roewer, 1949. Members of Beloniscidae are relatively homogeneous in their external morphology, but are recognised by well marked genitalic features. Male genitalia are described for exemplar species, and the morphology is compared with that of Epedanidae. Names are given to two new genitalic structures: sella curulis and pseudocalyx. http://zoobank.org/urn:lsid:zoobank.org:act:540BCE49-6F2E-4372-BFD4-D3C6068F045D http://zoobank.org/urn:lsid:zoobank.org:act:FE8B011B-AA6D-4E6C-A321-123542A0563F http://zoobank.org/urn:lsid:zoobank.org:act:E4A559CD-170A-40F2-924A-541C22974344

Two new species of Tomentella from the Lesser Xingan Mts. of northeastern China, T. pallidocastanea and T. tenuirhizomorpha, are described and illustrated using morphological characteristics and molecular phylogenetic analysis. T. pallidocastanea is characterized by mucedinoid basidiocarps adherent to the substrate, a light reddish brown to pinkish grey hymenophoral surface, absence of rhizomorphs and cystidia, generative hyphae with clamps, rarely with simple septa and echinulate, and subglobose to lobed basidiospores (echinuli up to 1.5 μm long). T. tenuirhizomorpha is characterized by mucedinoid basidiocarps separable from the substrate, a greyish brown to dark brown hymenophoral surface, thin rhizomorphs in the subiculum and margins, an absence of cystidia, generative hyphae with clamps rarely with simple septa and echinulate, and subglobose to globose basidiospores (echinuli up to 1.5 μm long). Molecular analyses using Maximum Likelihood, Maximum Parsimony and Bayesian Analysis confirm the phylogenetic position of the two new species. The discriminating characters of these two new species and their closely related species are discussed in this study.

Two New Species

Two new geckos from islands off the southeastern tip of New Guinea are not readily assignable to any currently defined genus but appear closely related to Nactus. The defining features of Nactus, however, have been uncertain because of variation among species assigned to this group, character convergence with other genera, and varying character emphases of different researchers. Moreover, relationships of Nactus to other gekkonine genera are uncertain because of homoplasy among the few characters used to infer higher-level relationships within Gekkoninae. I performed an analysis of phylogenetic relationships of my two new species to members of Nactus using a variety of other gekkonine and diplodactyline genera as outgroups. The results indicate the two new species are derived members of the genus Nactus that have undergone evolutionary reversal of some of the characters previously used to distinguish this genus. A further result of my analyses is that Nactus as currently conceived may prove paraphyletic or polyphyletic because its two most morphologically divergent species fail to cluster with the remaining members of this genus in all analyses. The two new species are herein described as Nactus sphaerodactylodes sp. nov. and Nactus acutus sp. nov. and may readily be distinguished from the other members of the genus by a variety of scalational features.

Abstract Numerous rivers, interrupted by large waterfalls and extensive rapids, drain the geologically ancient Guiana Shield Highlands. We describe a new armoured catfish genus and two new species endemic to the upper Ireng and Kuribrong rivers, respective tributaries of the Amazon and Essequibo basins in western Guiana. Corymbophanes ameliae sp. nov. is distinguished by having vermiculations on the abdomen, bands on the caudal fin, the anal fin i,5 and narrow caudal peduncle. Yaluwak primus gen. & sp. nov. is distinguished by having evertible cheek odontodes, a plated snout, a tall caudal peduncle and absence of adipose fin and iris operculum. We present a new molecular phylogenetic analysis inclusive of these and several related genera that suggests that the Corymbophanes clade (Araichthys, Corymbophanes, Cryptancistrus, Guianancistrus, Hopliancistrus and Yaluwak) originated in the Guiana Shield with secondary dispersal to the Brazilian Shield. Within the Guiana Shield, relationships among Corymbophanes and Yaluwak are consistent with geodispersal between drainages via headwater capture, although an uplift-mediated relictual distribution cannot be ruled out. ND2 haplotype structure among C. ameliae populations suggests that ichthyofaunal diversity on the Guiana Shield escarpment is shaped not only by inter-, but also intrafluvial barriers to gene flow.

Two fresh collections of Discosia were made from dead leaves of Fagus sylvatica in Italy. As these collections could not be cultured, the fruiting bodies were directly used for sequencing using a Forensic DNA Extraction Kit. Based on analyses of the concatenated internal transcribed spacer regions of the nrDNA operon (ITS) and large subunit rDNA (LSU) gene sequences, as well as morphological characters, the fresh collections are introduced as two new species, namely D. italica and D. fagi. Phylogenetically, these two species are distinct from all other Discosia species. Morphologically, D. italica is somewhat similar with D. fagi, but can be distinguished using dimension of conidiomata and conidiogenous cells. Descriptions and illustrations of the new taxa are provided herein.

Lithobius (Ezembius) longibasitarsussp. n. and Lithobius (Ezembius) datongensissp. n. (Lithobiomorpha: Lithobiidae), recently discovered from Qinghai-Tibet Plateau, China, are described. A key to the species of the subgenus Ezembius in China is presented. The partial mitochondrial cytochrome c oxidase subunit I barcoding gene was amplified and sequenced for eight individuals of the two new species and the dataset was used for molecular phylogenetic analysis and genetic distance determination. Both morphology and molecular data show that the specimens examined should be referred to Lithobius (Ezembius).

Two new species are described in the Neotropical genus Agaporomorphus Guignot from Suriname: A. hamatocolessp. nov. and A. tortussp. nov. The species are included in a phylogenetic parsimony analysis of 13 morphological characters and all 12 known species. Two equally parsimonious arrangements are found with the only difference a rearrangement among the A. knischi clade. Agaporomorphus tortus belongs to the A. dolichodactylus group based on presence of an elongate, club-like lobe on the dorsal, basal surface of the male median lobe and long, subsinuate male mesotarsal claws and a small lobe at the apex of male mesotarsomere V. Agaporomorphus hamatocoles does not belong to a known species group and is phylogenetically isolated lacking synapomorphies characterizing the other groups, so the species is placed in its own species group. Male genitalia are illustrated for the new species and redrawn for all the species of the A. dolichodactylus group, and male mesotarsal claws are illustrated for A. tortus and redrawn for other members of the A. dolichodactylus group. New distribution records are reported for Suriname for the species A. colberti Miller and Wheeler and A. pereirai Guignot.
