Cladocera, commonly known as ‘water flea’ due to the jerky movements produced by their second antennae, form an important food component for planktivorous fishes and other aquatic invertebrates. The present investigation comprising a collection of zooplankton samples from a shallow pond located in the Bishnah tehsil of Jammu district has revealed the presence of 13 Cladocera species belonging to the families Daphniidae, Chydoridae, Moinidae, Sididae, and Macrothricidae. Three species of the family Sididae belonging to the genus Diaphanosoma, namely, senegal, sarsi and excisum are new species records to the cladoceran fauna of Jammu & Kashmir. Presently, a detailed morphological analysis has been made on all the three Diaphanosoma species. They have shown major differences in their body size with D. senegal being larger than D. sarsi and D. excisum. All three species have well observable variability with reference to their head size, eye size, shell duplicature, shape of posterior valve margin, and the number of denticles so present on posterior valve margin. All the three species have also shown coexistence with each other, but D. senegal was dominant in terms of population density.

Three new species of oribatid mites of the family Galumnidae are described from soil and coniferous litter of Hogsback State Forest, Eastern Cape Province, South Africa. Pilogalumna hogsbackensis sp. nov. differs from Pilogalumna tenuiclava and P. ornatula by the presence of elongate oval postanal porose area and narrowly unilaterally dilated bothridial head. Pergalumna amatholensis sp. nov. differs from Pergalumna distincta by the presence of smaller body size, rounded rostrum, unilaterally dilated bothridial head, one pair of notogastral porose areas Aa, and the localization of opisthonotal gland opening and lyrifissure im. Stictozetes ihaguensis sp. nov. differs from all species of the genus by presence of bothridial seta with narrowly dilated head and median pore in both genders. An identification key to known species of Stictozetes is presented.

A new species of oribatid mite of the family Galumnidae, Pergalumna sistanbaluchestanica sp. nov., is described and illustrated based on adult specimens from soil in Sistan and Baluchestan province, southeastern Iran. The new species is characterized by dentate rostrum; long interlamellar setae; long, setiform, finely barbed bothridial setae; complete dorsosejugal furrow; large, nearly triangular porose areas Aa; presence of median pore in females and males; large, elongated postanal porose area and large body size. The new species is most similar morphologically to P. seminervosa Mahunka & Mahunka-Papp, 2008, however, differs from it in morphology of bothridial setae and notogastral porose areas Aa and also by the surface ornamentation of the pteromorphs and genital plates; localization of setal alveoli la and lyrifissures im and body size. An identification key to known species of Pergalumna from the Palaearctic region is given.

Two new species of oribatid mites of the family Oppiidae collected from leaf litter in Madagascar are described. Ramuselloppia indistincta sp. nov. differs from Ramuselloppia anomala by larger body size, the presence of epimeral tubercles  and comparatively long lamellar, interlamellar and notogastral setae and the absence of costulae and heads of bothridial setae. An identification key to known species of Ramuselloppia is provided. Lanceoppia (Baioppia) rugosa sp. nov. differs from all species of the subgenus by heavily rugose posterior part of the notogaster. The genus Ramuselloppia and subgenus Lanceoppia (Baioppia) are recorded in the Ethiopian region for the first time; the species Multioppia (Hammeroppia) wilsoni is recorded in Madagascar for the first time.

We describe a new species of Glassfrog of the family Centrolenidae. This new taxon, Terarohyla sornozai sp. nov., is diagnosed by having a protruding snout in lateral profile, uniform green dorsal colouration in life, concealed prepollex, extensive webbing between the outer fingers, fully webbed toes, and small body size. It inhabits the Non-Seasonal Evergreen Foothill and Lowland forests in the provinces of Esmeraldas, Imbabura, and Pichincha, north-western Ecuador.

AbstractThe genus Anonchus is revised. The genera Assia and Haconnus are considered to be synonymous with Anonchus on the basis of the morphological analysis. Additional descriptions of six species, viz. A. maculatus , A. mirabilis , A. millelacunatus , A. palaeotropicus , A. coomansi and A. pulcher are provided on the basis of type material or recently collected populations. The lectotype of A. monohystera is designated and described and the synonymy of this species with A. maculatus is confirmed. Two new species are described; A. winiszewskae sp. n. from Paraguay and A. venezolanus sp. n. from Venezuela. Several aspects of the morphology are described and the variability and diagnostic significance of the main morphological characters discussed. A study of intrageneric and suprageneric taxonomy of the genus Anonchus is presented. The subfamily Aphanolaiminae is reinstated for the genera Aphanolaimus, Aphanonchus and Paraphanolaimus and raised to family rank. The family Aphanolaimidae includes two subfamilies: Aphanolaiminae and Anonchinae. An emended diagnosis and a revised classification of Anonchus are proposed and a key to the species of the genus is provided.

The Relationship

The family Apidae, which is amongst the largest bee families, are important pollinators globally and have been well studied for their visual adaptations and visually guided behaviors. This review is a synthesis of what is known about their eyes and visual capabilities. There are many species-specific differences, however, the relationship between body size, eye size, resolution, and sensitivity shows common patterns. Salient differences between castes and sexes are evident in important visually guided behaviors such as nest defense and mate search. We highlight that Apis mellifera and Bombus terrestris are popular bee models employed in the majority of studies that have contributed immensely to our understanding vision in bees. However, other species, specifically the tropical and many non-social Apidae, merit further investigation for a better understanding of the influence of ecological conditions on the evolution of bee vision.

Four members of the family Renicolidae are described from Heron I., Australia. Adults of two new species are found in the kidneys of the black noddy, Anous minutus. Of these, Renicola foliata, sp. nov., differs from related species in the position of the ovary and testes, in the lobate gonads, in egg size, and in the presence of an oesophagus. R. caudescens, sp. nov., is distinguished by its body size, the lobation and position of the testes, the distribution of the vitellarian follicles and the size of the oral sucker. Also described are a renicolid metacercaria from the musculature of an atherinid fish, and a renicolid cercaria (cercaria F of Rohde, 1981) from the gastropod Planaxis sulcatus.

A New Species

A new species of oribatid mite of the family Galumnidae is described and illustrated based on adult specimens from soil in Mashhad county, Razavi Khorasan Province, northeastern Iran. Pilogalumna khorasanica sp. nov. is characterised by rounded rostrum; very long interlamellar setae; long, nearly setiform, finely bilaterally barbed bothridial setae; medially interrupted dorsosejugal furrow; elongated porose areas A2, very long and narrow, ribbon shaped A3 and large body size. The new species is most similar morphologically to Pilogalumna crassiclava longiareata (Pérez-Íñigo, 1976), however, differs from it in morphology of bothridial setae and structure of notogastral porose areas, by the presence of longer interlamellar setae and larger body size. An updated identification key to known species of Pilogalumna is presented.
