Alloperla Banks, 1906 (Plecoptera: Chloroperlidae) is a speciose genus of spring- and summer-emergent stoneflies known from the Oriental, eastern Palearctic, and Nearctic realms. Over 50 species are currently recognized. Alloperla clarki sp. nov. is described herein from the adult male stage from a small geographic area in the Appalachian Mountains in Virginia and West Virginia, USA. Diagnostic characters are presented with scanning electron microscope (SEM) photomicrographs. Alloperla clarki sp. nov. most closely resembles A. biserrata Nelson & Kondratieff, 1980, A. nanina Banks, 1911, and A. stipitata Surdick, 2004. These four species share similar characteristics of the male epiproct and appear to comprise a species group. The Alloperla nanina Group is formally proposed. Comparative SEM images are also provided for A. biserrata, A. nanina, and A. stipitata to assist with differentiating between these four species.

A new species of glycerid polychaete, Glycera sheikhmujibi, is described from the saltmarsh on the central coast of Bangladesh. The species is identified based on morphological characteristics using both a light microscope and scanning electron microscope (SEM). The species is characterized by the presence of three distinct types of proboscideal papillae: type 1 papillae (conical with three transverse ridges), type 2 (conical with a straight, median, longitudinal ridge), and type 3 (round, shorter, and broader, with a straight, median, longitudinal ridge). It has a Y-shaped aileron with gently incised triangular base, almost equal-size digitiform noto- and neuropodial lobes in the mid-body, and long ventral cirri at the posterior end. The new species is compared with its related species, previously described from the Bay of Bengal region. A key to all these species is provided.

A new species of Tabularia, Tabularia sinensis, is described from the inland Poyang Lake (Jiangxi Province), the largest lake in China. The description is based on light and scanning electron microscope observations of valve and girdle elements. Given the diversity of forms in the genus, the relationships and status of the genus was investigated in the context of the other known species in the genus and to ascertain if Tabularia, as originally circumscribed, remains monophyletic.

Anixiopsis biplanata sp.nov. is described as a new ascomycete isolated from soil at an altitude of 3100 m in Nepal. It is heterothallic and characterized by small, reddish brown ascospores (4 × 3 μm), which under the light microscope seem subrectangular to hexagonal in side view and appear smooth walled. Under the scanning electron microscope, however, they are tire shaped, ornamented with an equatorial reticulum and with two smooth, flat, lateral discs. Its anamorph is a Chrysosporium. Anixiopsis biplanata is briefly compared with the three other species already included in the genus Anixiopsis Hansen.

Alopecosa volubilis n. sp. is described from Korea and is differentiated from other species in Alopecosa Simon, 1885 by morphological characteristics, such as three retromarginal teeth of chelicera, smaller body size, and the presence of a distinct tip of the median apophysis. The pedipalpal sclerites and somatic characters of two similar species, A. moriutii Tanaka, 1985 and A. hokkaidensis Tanaka, 1985, are compared with those of the new species. An illustration of the body and scanning electron microscope (SEM) pictures of the pedipalpal organ are provided.

Studies carried out in tropical rain forest enclaves in semiarid region of Brazil revealed a new species of Calvatia. The basidiomata were collected during the rainy season of 2009 and 2012 in two states of Northeast Brazil. Macroscopic and microscopic analyses were based on dried basidiomata with the aid of light microscope and scanning electron microscope. Calvatia nodulata is recognized by its pyriform to turbinate basidiomata, exoperidium granulose to pilose and not persistent, subgleba becoming hollow at maturity, nodulose capillitium, and punctate basidiospores (3–5 μm). Detailed description, taxonomic comments, and illustrations with photographs and drawings are provided.

Merxmuellera setacea N.P. Barker from the south-western Cape. South Africa, is formally described. Descriptions of the morphology and leaf anatomy, in transectional and surface view, as observed under the light- and scanning electron microscope are given. Comparisons between this taxon and other southern African arundinoid species are made on the basis of morphological and anatomical observations. While the morphology of M setacea is in keeping with the generic limits of Merxmuellera Conert. the leaf blade anatomy appears to be intermediate between Merxmuellera, Pentameris Beauv. and  Pentaschistis (Nees) Spach.

Large collections of Australian Syllidae (Polychaeta) from the Australian Museum (Sydney) have been examined and identified, together with material from the Hamburgische Zoologische Museum der Universität (Hamburg, Germany), as well as some specimens from other museums. All known Australian species of the subfamily Syllinae belonging to Inermosyllis San Martín, 2003 (1 species), Megasyllis n. gen. (3 species), Opisthosyllis Langerhans, 1879 (5 species), and Trypanosyllis Claparède, 1864 (2 species), are described and figured. The Scanning Electron Microscope was used to illustrate relevant taxonomic characters and reproduction methods in these genera. Inermosyllis pseudohaploides is described as a new species. Megasyllis is described as a new genus, including M. corruscans (Haswell, 1885) and M. heterosetosa (Hartmann-Schöder, 1991) from Australia, and M. inflata (Marenzeller, 1879) from Japan and Australia; thespecies M. multiannulata (Aguado, San Martín & Nishi, in press) from Japan is also referred to this genus. The genus Inermosyllis is reported for the first time from Australia, as well as the species Opisthosyllis longicirrata Monro, 1939 and Trypanosyllis aeolis Langerhans, 1879.
