A new species of Caligus (Copepoda, Siphonostomatoida) from the plankton of the Caribbean coast of Venezuela with a key to species

During a survey of the zooplankton community of Bahía Amuay, Venezuelan Caribbean, specimens of an undescribed species of Caligus Müller were collected. It resembles Caligus xystercus Cressey and Caligus ocyurus Cressey, both known only from the Caribbean Sea. The new species can be distinguished from these and other congeners by a combination of characters including the armature of legs 1 and 4, but mainly by its unique female genital complex. This is the first species of Caligus described from Venezuela. The species is described in full and a key to the species of the genus recorded in Venezuela is provided.     

Heteronarce rierai,a new narkid ray from Mozambique,western Indian ocean

Heteronarce rierai sp. nov. is described on the basis of six specimens, one male and five females, caught in the waters off Mozambique (western Indian Ocean). Total lengths range from 257 to 296 mm. The new species is distinguished from the three other species of the genusHeteronarce by its narrower disc width (29.6% of TL in male, and 33.0 to 39.2% of TL in females), shorter disc length (32.7% of TL in male, and 34.4 to 40.6% of TL in females), and its longer interdorsal distance (10.1 to 11.7% of TL).     

Two new species of Andean gymnophthalmid lizards of the genus Euspondylus (Reptilia, Squamata) from central and southern Peru

Two new species of lizards assigned to the genus Euspondylus from the montane forests of the Peruvian Andes in the Pasco Department (central Peru) and Ayacucho Department (southern Peru) both at elevations of 2550 and 3450 m, respectively, are described. The new species are distinguishable from all other Peruvian and Ecuadorian species of Euspondylus by a unique combination of morphometric, scalation and color pattern characteristics. Natural history data for the new species and for Euspondylus spinalis are also provided.     

A new cave-dwelling loach, Triplophysa macrocephala (Teleostei: Cypriniformes: Balitoridae), from Guangxi, China

A new cave-dwelling species, Triplophysa macrocephala sp. nov. is described based on specimens collected from a karst cave in Renguang village, Lihu Town, Nandan County, Guangxi Zhuang Autonomous Region, China. The new species can be distinguished from its congeners by possessing the following combination of characters: pectoral fin not reaching beyond pelvic-fin origin; caudal fin forked; body smooth or scaleless; dorsal-fin origin anterior to pelvic-fin origin, edge of dorsal fin truncate; dorsal fin with eight branched rays; anal fin with five branched rays; eye small and vestigial; lower jaw arched with a median notch; air-bladder wrapped in bony capsule, lateral enlarged, posterior chamber of air-bladder degenerated.     

中国伊洛瓦底江和怒江褶鮡属鱼类的形态差异及分类地位

将采自中国伊洛瓦底江和怒江中115尾褶鮡属(Pseudecheneis)鱼类标本以采集地分为10组,对它们开展多变量形态度量学研究,共测量了25个框架性状和14个常规性状。经两次主成分分析,逐步提取分值散点聚在一起的标本,最终分离出5种不同的类型。第1类仅分布于伊洛瓦底江支流龙川江中下游,以其尾柄细长,区别于其他类型,确认为细尾褶鮡(P.stenura),其余4类均是未被描记的新种。第2类分布于伊洛瓦底江支流龙川江上游,体型极度纤细延长。第3类分布于怒江支流湾甸河,以胸鳍长为主要鉴别特征区别于其他类型,综合解剖学和分子生物学的系统发育研究结果,这类标本应是未被描记的一新种。第4类和第5类分别分布于怒江支流南汀河及伊洛瓦底江支流大盈江,它们以背部色斑的差异相互区分。此外,腾冲曲石部分标本的度量数据无法与大盈江的标本区分,外部形态特征亦无差异。它们是同一种类的不同地理种群,还是不同的种类,或者腾冲曲石的这些标本是另一新种?这些猜测均有待后续采用其他方法研究后进一步确认。     

A new species of Philometra Costa, 1845 (Nematoda: Philometridae) from the freshwater fish (red piranha) Pygocentrus nattereri Kner (Characidae) in Amazonia, Brazil

A new nematode species, Philometra nattereri n. sp. (Philometridae), is described from female specimens found in the oculo-orbits and nasal cavity of the red piranha Pygocentrus nattereri Kner (Characiformes: Characidae) from five lakes in Central Amazonia, Brazil, collected in 2008 and 2009 (overall prevalence 12%, intensity 1?C3 nematodes per fish). Based on light and scanning electron microscopical examination, the new species differs from most other congeners parasitising freshwater fishes in that its oesophageal gland extends anteriorly far anterior to the level of the nerve-ring, in the presence of 14 small cephalic papillae arranged in two circles and in having two minute caudal projections. This is the first species of Philometra Costa, 1845 reported from fishes of the family Characidae and the second valid species of this genus parasitic in freshwater fishes of Brazil and South America.

Records of anglerfishes (Lophiiformes: Lophiidae) from the western South Pacific Ocean, with descriptions of two new species

Species of Lophiidae collected from the western South Pacific Ocean are examined. Nine nominal species are recognized, all but one species with their distributions extended eastwards and southwards from the western Pacific Ocean. Two new species are described from Polynesia. Lophiodes iwamotoi n. sp. is described from five specimens collected from Savannah Seamount. It is characterized by a relatively long third dorsal-fin spine (56.9-70.8% standard length, L(S)) that extends (when retracted) to between the end of the soft dorsal fin and caudal-fin base; a relatively short fifth dorsal-fin spine (10.5-13.1% L(S)); a relatively short and narrow head; 19-20 pectoral-fin rays. Lophiodes maculatus n. sp. is described from 20 specimens collected from Marquesas Islands. It is characterized by an extremely long third dorsal-fin spine (71.9-87.2% L(S)), extending well beyond the caudal-fin base; a relatively short fifth dorsal-fin spine (11.4-16.5% L(S)); 17-18 pectoral-fin rays. A key to the lophiids in the western South Pacific Ocean is provided.     

The species of Hymenoptera described by Linnaeus in the genera Sphex, Chrysis, Vespa, Apis and Mutilla

Data are presented on the type-material representing the species described by Linnaeus in his genera Sphex, Chrysis, Vespa, Apis and Mutilla , The names here considered total 158; six are currently applied in the Hymenoptera Parasitica. Of the balance of 147, three are emendations and five are unavailable homonyms or names proposed in the synonymy of other species. Fifteen Linnaean names are here placed as synonyms. One name is attributed to an author other than Linnaeus, and live names remain species incertae sedis. The remainder, 118, are applied as valid names in die Hymenoptera Aculeata. Holotype specimens in London, Uppsala or Stockholm represent 60 names; 55 names are based on lectotype specimens of which 49 are here designated, two by other authors. One name is represented by a neotype specimen in Lund, and one by a lectotype figure. One non-aculeate species is based on syntypes. Specimens appear to be lost with respect to 25 names; three specimens in Uppsala may be the holotypes of a further three species.
Eight new combinations are made, and twelve new synonyms established; three further new combinations and three further new synonymies are suggested. A systematically arranged summary of species treated and of nomenclatural changes made is given. Nomenclatural changes affecting non-Linnaean names are included where relevant; lectotypes are designated for two non-Linnaean species.

浙江鹿城发现云开脊蛇和黄家岭脊蛇

2022年9月和2023年4月在浙江省温州市鹿城区仰义水库分别采集到1条脊蛇属（Achalinus）物种幼体尸体标本（标本编号分别为2022AZJLCN1和2023AZJLCN2）。形态上它们分别与黄家岭脊蛇（A. huangjietangi）和云开脊蛇（A. yunkaiensis）接近。基于线粒体COI基因片段的最大似然树结果,两蛇样本序列分别与这两种脊蛇聚为一个支系;2023AZJLCN2标本与云开脊蛇的遗传距离为0.10,低于中国境内分布脊蛇属物种间的遗传距离（0.12～0.16）;2022AZJLCN1标本与黄家岭脊蛇的遗传距离为0.09,在黄家岭脊蛇种内遗传距离（0.04～0.12）范围内。综上,鉴定2023AZJLCN2标本为云开脊蛇,2022AZJLCN1标本为黄家岭脊蛇。此前记录云开脊蛇分布于我国广东和广西,本次在浙江温州市鹿城区的发现为浙江蛇类新分布记录种;黄家岭脊蛇分布于安徽和浙江,此次在在温州市鹿城区的发现是温州市首次新分布记录。这两种脊蛇的新分布记录提示它们有更广的分布范围。     

A new species of Triatominae from Tamil Nadu, India

Abstract A new species of the genus Linshcosteus Distant, 1904 (Hemiptera: Reduviidae: Triatominae) is described from specimens collected near Kalakkadu, Tamil Nadu state, southern India. Specimens were found in deep crevices between rocks, in a region of semi‐arid scrub jungle. The distinctiveness of the new species was demonstrated by a morphometric analysis including the five previously described species of Linshcosteus, all from India. Nine measurements of the head were used in an isometric size‐free principal component analysis. In terms of discrete morphology the new species, Linshcosteus karupus sp.n. Galvão, Patterson, Rocha & Jurberg differs from the most similar one, L. kali Lent & Wygodzinsky, 1979 , by its very prominent anterolateral projections of the pronotum, by the length to width ratio of the pronotum, by the pilosity of the head and several other characters, including phallic structures. A revised key is presented for the six species of the genus.     

Redescription of the deep-sea octopod Benthoctopus normani (Massy 1907) and a description of a new species from the Northeast Atlantic

A long-synonymized species Benthoctopus normani (Massy 1907) (Cephalopoda: Octopodidae) is redescribed from material collected over 30 years by the National Oceanography Centre, Southampton and the National Museums of Scotland. It can be distinguished from other octopodid specimens found in deep waters of the Northeast Atlantic by its biserial suckers, lack of ink sac, and simple ligula, which lacks transverse ridges. Examination of the collections led to the identification of a new species of Benthoctopus from the Northeast Atlantic, which is described herein.     

内蒙古上渐新统中Yindirtemys(啮齿目,梳趾鼠科)的发现

在内蒙古上渐新统伊克布拉格组中发现的 Yindirtemys 的新材料证明,Yindirtemys woodi 是 Tataromys grangeri 的晚出的同物异名,但 Tataromys grangeri 的特点与典型的 Tataromys 的区别很大,而 Yindirtemys 属仍是有效的.因此,这个种应从 Tataromys 属中排除,而归人 Yindirtemys 属.     

Length‐weight relationships of five fish species from the Daninghe River,China

Length‐weight relationships were described for five fish species belonging to three families and four genera from the Daninghe River, one of primary tributaries of the upper Yangtze River, China. A total of 1894 specimens were collected from 2014 to 2016 by using electro‐fishing equipment. Length–weight relationships for five species were recorded previously in FishBase and new maximum total lengths for five species were also presented in this paper. The results will be useful for fishery research, management and conservation in the upper Yangtze River Basin.
