A comprehensive molecular phylogenetic analysis of the family Thamnophilidae indicated that the genus Myrmotherula is not monophyletic. The clade composed of M. guttata and M. hauxwelli is only distantly related to other members of the genus and should be removed from Myrmotherula. The phenotypic distinctiveness of the clade argues against merging it with its sister group Thamnomanes and no generic name is available for the guttata-hauxwelli clade. Consequently, we describe the genus Isleria for these two species, and designate Myrmothera guttata as its type species.

Generic Position

Several species of the family Xeniidae, previously assigned to the genus Cespitularia Milne Edwards & Haime, 1850 are revised. Based on the problematical identity and status of the type of this genus, it became apparent that the literature has introduced misperceptions concerning its diagnosis. A consequent examination of the type colonies of Cespitularia coerulea May, 1898 has led to the establishment of the new genus Conglomeratuscleragen. n. and similarly to the assignment of Cespitularia simplex Thomson & Dean, 1931 to the new genus, Caementabundagen. n. Both new genera are described and depicted and both feature unique sclerite morphology, further highlighting the importance of sclerite microstructure for generic position among Xeniidae. Freshly collected material was subjected to molecular phylogenetic analysis, whose results substantiated the taxonomic assignment of the new genera, as well as the synonymies of several others.

Neochloroglyphica gen. nov. and its type species N. perbella sp. nov. are described from Yunnan, China. Morphological characters and molecular phylogenetic analysis, based on one mitochondrial and three nuclear genes, support the hypothesis that Neochloroglyphica is a member of the tribe Neohipparchini, and that it is a sister genus to Chloroglyphica. Morphological characters, including those of the genitalia, are figured and compared with related genera, especially Chloroglyphica, Neohipparchus and Chlororithra. Diagnoses for the genus and the species are provided and illustrations of external features and genitalia are presented.

A New Species

Because of the problematical identity and status of the type of the xeniid soft coral genus Cespitularia Milne-Edwards & Haime, 1850, the species C. stolonifera Gohar, 1938 is revised. Examination of the type colonies has led to the establishment of the new genus Unomia gen. n. which is described and depicted. This genus features a stalk, commonly divided into branches featuring a diffuse polypiferous part consisting of distal clustered polyps and proximal individual ones on the stalk or the basal membranous part of the colonies. The sclerites are ellipsoid platelets composed of dendritic calcite rods whose tips are distinct on the surface of the platelets. Freshly collected material from Venezuelan reefs where the species is invasive was subjected to molecular phylogenetic analysis, the results of which substantiate the taxonomic assignment of the new genus under U. stolonifera comb. n. A new species, U. complanatis, from Japan and Green Island (Taiwan) is described and further illustrates the extent of the interspecific morphological variation within the genus. The results reveal that the biogeographic distribution of Unomia gen. n. includes Pacific Ocean reefs in addition to the previously reported invaded Caribbean reefs.

A New Species

A new species of the continental shelf hyperbenthic genus Pilarella is described, the first from the Indo-Pacific. This is the second species of Pilarella known, and the first description of a male in the genus. The new species is easily distinguished from other species of Pilarella (P. longicornis) based on: (1) short caudal rami, approximately 1.5 times longer than wide; (2) 2 setae on the mandibular endopod; (3) 6 setae on the maxillular coxal epipodite; and (4) in the female, a short left antennule reaching the posterior border of the genital double-somite. The new diagnosis of Pilarella differs from Metacalanus in the separation of ancestral segments IX–XII and XIV–XV of the antennule, and the presence of 5–6 setae on the maxillular praecoxal arthrite. Pilarella is also separated from Metacalanalis based on the absence of a seta on the third ancestral segment of the antennary exopod, the symmetry of legs 1–3, the presence of a medial basal seta on the female leg 5, and 2 lateral exopodal spines on the female leg 5. A molecular phylogenetic analysis of some representative genera of the family Arietellidae, including the present new species, recovers two arietellid clades (Metacalanus- and Arietellus-clades) as in previous studies. Dichotomous keys for the genera of Arietellidae and the species of Pilarella are included.

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

Phylogenetic Affinities

One of the major problems hindering the systematic study of tachinid flies is that genera are often poorly defined, making it difficult to unambiguously assign species among closely related genera. Within the tribe Winthemiini, an example of this problem is represented by the unstable classification of the Afrotropical species most recently classified as Smidtia capensis (Schiner). This species has been previously assigned to four different genera on the basis of limited examination and evidence. Here, we evaluate the identity and phylogenetic affinities of this species and other members of the tribe Winthemiini using morphological and molecular phylogenetic analysis. We demonstrate that S. capensis actually belongs to the genus Winthemia Robineau-Desvoidy. We also find that Winthemia is paraphyletic with respect to two monotypic genera, Crypsina (type species Crypsina prima Brauer & Bergenstamm) and Hemiwinthemia (type species Hemiwinthemia calva Villeneuve). On the basis of morphological and genetic evidence, we propose to extend the generic limits of Winthemia to include W. londti, sp. nov. (South Africa), W. capensis (Schiner), comb. nov. (South Africa), W. prima (Brauer & Bergenstamm), comb. nov. (China, Japan, Australia) and W. calva (Villeneuve), comb. nov. (D.R. Congo), thus synonymising with Winthemia the generic names Crypsina, syn. nov. and Hemiwinthemia, syn. nov.

Based on our molecular phylogenetic analysis of haplolepideous mosses with concatenated sequences of chloroplast rps4 and rbcL genes, a new family Timmiellaceae is erected to accommodate the genera Timmiella and Luisierella, both of which have been formerly included in the family Pottiaceae.  The family Timmiellaceae is resolved as a second-branching clade together with Distichium (Distichiaceae) within the Dicranidae (haplolepideous moss) lineages and phylogenetically distinct from the Pottiaceae.  Reassessment of morphological characters suggests that a combination of the characters: 1) adaxially bulging and abaxially flat leaf surfaces, 2) sinistrorse or straight peristomes, when present, and 3) sinistrorsely arranged operculum cells is unique to Timmiellaceae and discriminates it from other haplolepideous moss families.
