A new species of clingfish, Dellichthystrnskii sp. n. is described on the basis of 27 specimens, 11.9–46.0 mm SL, collected from intertidal and shallow coastal waters of New Zealand. It is distinguished from its only congener, D.morelandi Briggs, 1955 by characters of the cephalic sensory system and oral jaws, snout shape, and colouration in life. A rediagnosis is provided for D.morelandi, which is shown to exhibit sexual dimorphism in snout shape.

A New Species

An unusual new omaliine species, Anthobium alekseevisp. nov., is described and illustrated from Eocene Baltic amber, tentatively placed in the megadiverse genus Anthobium Leach, 1819. A new monotypic species-group is established. The new species can easily be distinguished from other species of the genus by the larger body, shape of the subrectangular pronotum, and the presence of a median carina on the prosternum and large, subtriangular tooth on the inner side of each mesotibia, likely exhibiting a peculiar sexual dimorphism in the male. Based on the study of the specimen with support of microtomographic images, a brief comparative analysis of a new species with described extant species of Anthobium is provided.

Abstract We describe a new species of Aratinga—A. pintoi (Sulfur-breasted Parakeet)—from open areas on the northern bank of the lower Amazon River in the state of Pará, Brazil. It was for a long time misidentified as a juvenile of A. solstitialis or a hybrid between that species and A. jandaya. It can be distinguished from other Aratinga species by the combination of the following characters: mantle and wing coverts green, suffused with pale yellow; underparts pale yellow, with pale orange restricted to belly and flanks; and feathers on the underparts with a dark rachis. On the basis of color characters and general morphology, we suggest that this new species should be a member of a group composed of A. solstitialis, A. jandaya, A. auricapillus, and, possibly, Nandayus nenday. A review of taxonomy and distribution of the group is also presented.

A New Species

A new species of the genus Euscorpiops Vachon, 1980 is described, based on specimens collected from Menglian County, Yunnan Province, China. It is characterized by the following characters: (1) pectinal teeth number 7–7 in females and 8–8 in males; (2) cheliceral movable finger with 6–7 basal teeth on ventral edge; (3) chela ratio of length to width over 3.5 in females and over 4.1 in males; (4) a slight lobe on movable finger and corresponding notch on fixed finger in both males and females, with no marked sexual dimorphism; (5) patella with 19 external trichobothria (6eb, 2esb, 2em, 4est, 5et), and with 10 ventral trichobothria. With the species described in the present publication, the number of known species of Euscorpiops is raised to 17.

A New Species

Pugettia quadridens (De Haan, 1837) and its closely similar congener, P. intermedia Sakai, 1938, are redescribed and illustrated and their possible infraspecific variations related to sexual, ontogenetic, and environmental differences are discussed. As a result, a new species, Pugettia ferox, which had long been believed to be a local variant of P. quadridens sensu lato in the northeast Japan, is described. Despite moderate sexual dimorphism and considerable variability related to their ontogeny, the three species can be distinguished from each other by the combination of various morphological characters including the structure of the orbital region and male first gonopods. The patterns of ontogenetic morphological and morphometric changes in the chelipeds, gonopods, and pleons are also differentiated among the three species. The updated distribution ranges of three species greatly overlap in the northeast Asian waters, although P. quadridens sensu stricto is distributed more southward than P. ferox n. sp.. Distinguishing characters between P. quadridens s.s. and P. pellucens Rathbun, 1932, and between P. intermedia and P. vulgaris Ohtsuchi, Kawamura & Takeda, 2014, are revised.

A New Species

Corotoca Schiødte, 1853 is a Neotropical genus of termitophiles beetles, with five species, and its description marks the first record of insects associated with termites. A new species, Corotoca fontesi sp. nov., from Brazil, is described and illustrated, and a taxonomical problem regarding to the identification and nomenclatural status of two species, Corotoca phylo Schiødte, 1853 and Corotoca seeversi Fontes, 1977, is solved. Therefore, Corotoca seeversi is proposed as a new junior synonym of C. phylo, and the material identified as C. phylo housed in the Museum of Zoology of the University of São Paulo, Brazil (MZUSP) is recognized as a new species, Corotoca fontesi sp. nov. New morphological and sexual dimorphism data in the species, and solution of some messy informations about the genus present in the literature are also present.
