der M. orientalis Ferrière, 1935 n. syn., M. vuilleti (Crawford, 1912) under M. pulchriceps Cameron, 1905 n. syn., and Semianastatus orientalis Kalina, 1984 and Mesocomys kalinai Özdikmen, 2011 under M. albitarsis (Ashmead, 1904) n. syns. Lectotypes are newly designated for M. menzeli, M. obscurus, M. orientalis, M. pauliani, M. pulchriceps and M. vuilleti. Morphological features characteristic of the genus and of the highly dimorphic sexes are described and illustrated, and the species are keyed, described, and illustrated through macrophotography. Phylogenetics are discussed for the genus, the two species groups, and species within the pulchriceps group. Distribution and host records are also summarized for each species.A new species of the family Agnaridae, Lucasioides altaicus sp. nov., is described from the Altai Mountains, southwestern Siberia, based both on morphological characters and molecular data. This species is the first record of Lucasioides from Russia, whose location is the northernmost habitat of terrestrial isopods in indigenous habitats presently known to Eurasia. The diagnostic characters of the new species and a preliminary phylogenetic analysis within Agnaridae are provided.Two new species of the cestode genus Caulobothrium, collected from the duckbill eagle ray, Aetomylaeus bovinus, off Senegal, are described. Although postulated as sister taxa in an earlier molecular phylogenetic analysis, Caulobothrium multispelaeum n. sp. and Caulobothrium katzi n. read more sp., respectively, are among the smallest and largest members of the genus. The smaller species is unique among its congeners in possessing unusual medial longitudinal grooves along the dorsal and ventral surfaces of its strobila that develop into a tandem series of elliptical apertures on the posterior proglottids. The inner surfaces of these apertures stained positively with McManus' periodic acid Schiff in a manner similar to that seen in members of the distantly related lecanicephalidean genus Elicilacunosus. The larger species differs from its congeners in size, number of proglottids, and arrangement of bothridial loculi. Both new species were found to possess a small apical sucker on the anterior margin of each of their bothridia. Scanning electron microscopy (SEM) and frontal sections of a bothridium of Caulobothrium tetrascaphium suggests that this species also bears an apical sucker. Examination of the hologenophore of the species provisionally referred to as Caulobothrium n. sp. 5 in the earlier molecular analysis indicates it is conspecific with the recently described Caulobothrium pedunculatum, which was also determined to possess bothridial apical suckers. This leads us to suspect that this feature may be found to occur in all members of the genus. SEM of specimens of Caulobothrium for the first time indicates their bothridial surfaces are covered with filitriches of various sizes but lack spinitriches; spinitriches were seen only on the cephalic peduncle of C. katzi n. sp. The geographic distribution and host associations of Caulobothrium are expanded to include data now available for all species. The diagnosis of the genus is revised to include all of this information.We describe a new species of large green treefrog from southern Papua Province, Indonesia. Litoria lubisi sp. nov. is placed in the L. infrafrenata Group based on its size, colouration and configuration of hand webbing, but differs from other members of this group in aspects of body size and proportions, extent of hand webbing, colouration and male advertisement call. Litoria lubisi sp. nov. occurs in close proximity to two other species in the L. infrafrenata Group, emphasising an until-recently overlooked pattern that multiple species of large, arboreal Litoria have overlapping distributions across much of the lowlands of southern New Guinea.The known distribution of Macrourus caml is extended to the Ob and Lena Banks area, and southwest of Heard and McDonald Islands. Macrourus holotrachys was recorded from Prince Edward Islands and the Ob and Lena Banks. Macrourus carinatus specimens examined were all from Prince Edward Islands, the type locality. Macrourus whitsoni specimens examined were all from the southeast Atlantic Ocean at about 69˚S, close to the Antarctic continent (off Maud Land), consistent with a previous study which reported the species from 64-77˚S. A revised identification key is provided.Two new deep-sea Henricia species, Henricia margarethae n. sp. and Henricia fragilis n. sp. are described from Sagami Bay and the Ogasawara Islands in Japan. The two new species show an affinity with eight congeners in having multiple furrow spines and abactinal papular areas which are larger than surrounding plates. The two species described herein are characterized by the arrangement of abactinal pseudopaxillae, the arrangement of abactinal papulae, the shape and arrangement of abactinal spines, the length of intermarginal and ventrolateral series, and the armament of superomarginal, inferomarginal, and adambulacral plates.Considering the importance of establishing different approaches to the early detection of invasive species, the present study aimed to describe and illustrate the morphology of the early larval stages of the shrimp Lysmata lipkei, an invasive species in the Western Atlantic. Additionally, we did a morphological comparison and a review of the other Lysmata species from the Western Atlantic Ocean with a known larvae description. The larvae used in this study were obtained by the maintenance, under laboratory conditions, of ovigerous hermaphrodites of L. lipkei, collected in the wild. Then, larvae were dissected under a stereo microscope and illustrated using a microscope equipped with a camera lucida. The first three larval stages (zoeae) of L. lipkei were illustrated, described, and compared to other species of Lysmata previously described of the Western Atlantic. Some features of the larval morphology of L. lipkei are very similar when compared to other Lysmata species with previous larval descriptions, such as a rostrum long and simple, the eyes stalked with a long peduncle from the second zoeae, one pterygostomian spine and several denticles along the anterior ventral margin of the carapace, similarities in the segmentation of the maxillipeds, and the presence of dorsolateral spines on the posterior margin of the 5th pleomere, among other features. Also, unique features were observed for L. lipkei, such as differences in the setation of some structures, including the antennule, antenna, maxillule, and maxillipeds. Using the morphological descriptions, we expect to identify species from the plankton, especially invaders, that might be present in the Western Atlantic, as well as assist in several areas in which the larval morphology is relevant.
