The species of the genus Micrambe Thomson 1863, from South Africa (Coleoptera: Cryptophagidae)

The 22 species of the genus Micrambe Thomson known from South Africa are analyzed and revised. Micrambe danielssoni sp. nov is described. Following a detailed study of the type material in different entomological collections, the status of two taxa is revised and two new synonymies are proposed: Micrambe kolbei Grouvelle 1908, syn. nov. for Micrambe minuta Grouvelle 1908, and Micrambe similis Bruce 1957, syn. nov. for Micrambe peringueyi Grouvelle 1908. A lectotypus is designated for one taxon: Micrambe capensis (Redtenbacher 1867). A key to all the species occurring in South Africa is presented.     

A new species of the genus Mekongina Fowler, 1937 (Cypriniformes: Cyprinidae) from South China

A new species of cyprinid fish, Mekongina lancangensis, is described from the upper Mekong River drainage in Southern Yunnan, China. The new species is distinguished from the other species of Mekongina occurring in the lower Mekong River drainage by possessing the following combination of characters: one pair of rostral barbels; two rows of tubercles irregularly scattered on the snout and cheeks, with two enlarged tubercles present at each side of anterior of the snout; 19–27 rostral marginal lappets; lateral line with 38–41 scales; 5·5 or 6·5 scales in transverse series from dorsal‐fin origin to lateral line; 18–20 circumpeduncular scales; snout length 31·9–36·9% head length; tip of depressed anal‐fin rays extending to the caudal‐fin base.     

Neogosseidae (Gastrotricha,Chaetonotida) from the iSimangaliso Wetland Park,KwaZulu-Natal,South Africa

Among the mostly benthic gastrotrichs, the Neogosseidae (Gastrotricha, Chaetonotida) are particularly interesting from an evolutionary point of view in virtue of their planktonic lifestyle; yet, they are poorly known and uncertainties concerning morphological traits hamper accurate in-group systematics. During a recent survey of meiofauna in the iSimangaliso Wetland Park, South Africa, two species of Neogosseidae were found in a freshwater pond near Charter’s Creek on the Western Shores of Lake St Lucia. Based on morphological traits, one species has been identified as Neogossea acanthocolla, originally described from Brazil, while the other, affiliated to the genus Kijanebalola, is proposed as new to science. Using a combination of differential interference contrast and scanning electron microscopy, fine anatomical details were observed and are here discussed in a larger taxonomic framework, especially regarding Kijanebalola devestiva sp. n. Results have also provided reasons for a revision of the diagnostic traits of Kijanebalola, Neogossea and the whole Family Neogosseidae. Besides expanding awareness about the biodiversity hosted by South Africa’s first UNESCO World Heritage Site, our study will be beneficial to future phylogenetic studies of the Gastrotricha based on morphology, by allowing the selection and/or a more precise character coding of traits of phylogenetic relevance.     

A new branchipodid genus and species (Crustacea: Branchiopoda: Anostraca) from South Africa

Rhinobranchipus martensi gen. et sp. nov. (Anostraca: Branchipodidae) was collected from a shallow temporary pool in the surroundings of Grahamstown (Cape Province, South Africa) (33^o18'S, 26^o32'E). Rhinobranchipus shares partial fusion of the chitinized basal parts of the male antennae, the so-called clypeus, with other Branchipodidae. The new genus is distinguished from confamilial genera by the morphology of the basal part of the penes. The new species, known from its type locality only, should be considered endangered, if it has not already become extinct as a result of recent modifications of its habitat.     

Descriptions of two new species of the botiid genus Leptobotia Bleeker, 1870 (Teleostei: Cypriniformes) from South China

Two new species of Leptobotia are here described as L. rotundilobus from the Xin'an-Jiang of the upper Qiantang-Jiang basin in both Anhui and Zhejiang Provinces and the Cao'e-Jiang in Zhejiang Province, and L. paucipinna from the Qing-Jiang of the middle Chang-Jiang basin in Hubei Province, South China. Both have a plain brown body as found in L. bellacauda Bohlen & Šlechtová, 2016, L. microphthalma Fu & Ye, 1983, L. posterodorsalis Chen & Lan, 1992 and L. tientainensis (Wu, 1930). The two new species are distinct from these species in vertebral counts, further from L. posterodorsalis in vent placement and further from the other three species in pectoral-fin length. Both differ in caudal-fin coloration and shape, and dorsal-fin location and coloration, and also in internal morphology. Their validity is confirmed by their own monophyly recovered in a phylogenetic analysis based on the mitochondrial cyt b and COI genes.     

A new genus of Entiminae from North Africa,supported by a phylogenetic analysis (Coleoptera: Curculionidae: Entiminae)

The genus Holcophloeus gen. nov. is here proposed to include Trachyphloeus cruciatus Seidlitz, 1868, and two new species native to North Africa, based on a phylogenetic analysis and an evaluation of the diagnostic characters. The taxonomic position of Holcophloeus in relation to the tribes Trachyphloeini Lacordaire, 1863, and Holcorhinini Desbrochers, 1898, is discussed, and the new genus is attributed to the Holcorhinini. Holcophloeus laurae sp. nov. from south‐eastern Morocco and Holcophloeus weilli sp. nov. from northern Libya are described and illustrated and a key to the species of the new genus is given. The lectotype of Trachyphloeus cruciatus Seidlitz, 1868, is designated. The genus Massimiellus Borovec, 2009, is transferred from Trachyphloeini to Holcorhinini. © 2013 The Linnean Society of London     

A new goby (Teleostei: Gobiidae) from the South China Sea and its significance for gobioid classification

A new genus and species of gobiid fish, Egglestonichthys Patriciae , is described from the South China Sea. Certain features of the modified head lateral-line system resemble those seen in eleotrine genera with 'transverse' suborbital sensory papillae, but the skeleton of the new goby is essentially gobiine. Aspects of the lateral-line system indicate closest relationship with genera from both the IndoPacific area ( Callogobius complex, Psilogobius, Stonogobiops ) and the New World ( Microgobius ). Wider affinities with other gobiine and gobionelline genera are discussed. Discrepancies between arrangements based predominantly on lateral-line characters and on osteology are noted and their implications considered for future classification of the gobioid fishes.     

Reassessment of the isopod crustacean Aega deshaysiana (Milne Edwards, 1840) (Cymothoida: Aegidae): a world-wide complex of 21 species

Aega deshaysiana (Milne Edwards, 1840) and A. antillensis Schioedte & Meinert, 1879, have long been confounded, with all records eventually becoming regarded as belonging to one globally distributed species, namely A. deshaysiana. These two species are redescribed and differentiated, with A. schioedteana Bovallius, 1885 remaining in synonymy with A. deshaysiana. Aega deshaysiana occurs only in the eastern North Atlantic and Mediterranean, while A. antillensis is known only from the Caribbean and Gulf of Mexico. A further two named species are redescribed: A. excisa Richardson, 1910, previously placed in synonymy with A. deshaysiana, and A. magnifica (Dana, 1852). A neotype is designated for A. magnifica. This ‘complex’ or group of Aega species is distinguished from the others by their large eyes, which are usually medially united and occupy most of the head, their large adult size (20–60 mm), a posteriorly acute and defined pleotelson apex, and the uropod rami not extending posteriorly beyond the pleotelson, with exopod held at an oblique angle to the endopod and deeply notched endopod lateral margin. The group is not necessarily monophyletic, as there is a gradation in the depth of the uropod notch from deep to scarcely evident, and in eye size from entirely occupying the head to just separate (though the eyes are always large). Twelve new species in the group are described. All species are considered to be micropredators of fishes and elasmobranches, although prey records are few and unreliable owing to the readiness of these isopods to detach. Species of the group have been recorded from depths varying between 10 m and 600 m and occasionally deeper. Several have extensive distributions ranging from the Southern Ocean to tropical waters. The group is represented in all oceans. © 2004 The Linnean Society of London, Zoological Journal of the Linnean Society, 2004, 142 , 135–232.     

Anzygina, a new genus for some Australasian microleafhopper species formerly placed in the genus Zygina Fieber (Cicadellidae: Typhlocybinae: Erythroneurini)

Species of Erythroneurini (Cicadellidae: Typhlocybinae) currently placed in the genus Zygina and found in Australia, New Zealand and some neighbouring islands are transferred to the new genus Anzygina , type species Erythroneura sidnica Kirkaldy, following comparison with the type species of the genus: Typhlocyba nivea Mulsant and Rey. New combinations are Anzygina sidnica (Kirkaldy), Anzygina honiloa (Kirkaldy), Anzygina melanogaster (Kirkaldy) and Anzygina sativae (Evans) from Australia, Anzygina toetoe (Cumber), Anzygina agni (Knight), Anzygina dumbletoni (Ghauri) and Anzygina ramsayi (Knight) from New Zealand, Anzygina zealandica (Myers) from Australia and New Zealand, Anzygina jowettae (Knight) from Norfolk Island and Anzygina medioborealis (Ghauri) from Papua New Guinea. Lectotypes are designated for Erythroneura honiloa Kirkaldy and E. sidnica Kirkaldy. Anzygina billi sp.n. is described from SE Qld, and Anzygina barrattae sp.n. is described from the South Island of New Zealand. A. agni is a new record for Australia and is presumed to be Australian in origin. A. dumbletoni has a distribution which suggests that it also is introduced to New Zealand although its origins are not known. A. ramsayi, A. barrattae and A. toetoe , all of which appear to be New Zealand endemics, show affinity with each other based on aedeagal structure. A key to these species, based on males, is provided. The lack of male syntypes for Erythroneura honiala Kirkaldy and Erythroneura lubra Kirkaldy precludes establishment of their identities relative to other species of the genus, and both names are regarded as having nomen dubium status. Australian species not transferred to Anzygina are Zygina evansi (Ross) and Zygina ipoloa (Kirkaldy), both of which belong elsewhere.     

Olemehlia krali,a new genus and species of Ripidiinae from Baltic amber (Coleoptera: Ripiphoridae)

A new genus and species, Olemehlia krali n. g. & n. sp. (Coleoptera: Ripiphoridae: Ripidiinae), is described from Baltic amber. The newly described genus is compared with all known fossil and extant closely related genera of the subfamily Ripidiinae. It is characterised by the following combination of characters: antennae consisting of 10 antennomeres, with scape, pedicel, and antennomere 3 simple and antennomeres 4–10 uniflabellate, mouthparts reduced to a small single unpaired tubercle, postocular ommatidia absent, pronotum trapezoid without grooves or impressions, elytra without white apical spots, tarsal formula 5–5–4, hind tarsomere I shorter than three remaining combined. Diversity of Ripiphoridae in Baltic amber is discussed; key to Ripidiinae genera from Baltic amber is provided.     

A new genus of Grapholitini from Africa related to Thaumatotibia (Lepidoptera,Tortricidae)

Thaumatovalva gen. n. is described and illustrated from the Afrotropical region. As currently defined the genus includes four species: T. deprinsorum sp. n. from the Democratic Republic of Congo; T. albolineana sp. n. (type species) from the Democratic Republic of Congo; T. spinai (Razowski & Trematerra), comb. n., from Ethiopia and Nigeria; and T. limbata (Diakonoff), comb. n., from the Seychelles and Kenya. Thaumatovalva limbata has been reared from the fruit of Cordia somaliensis Baker and C. monoica Roxb. (Boraginaceae) in Kenya. Although structures of the male and female genitalia are extremely similar among three of the four species, male secondary scales on the under surface of the hindwing easily distinguish them.     

Notes on the genus Neochauliodes Weele (Megaloptera: Corydalidae) from Henan, China

The species of the genus Neochauliodes from Henan are reviewed. Three species are described as new to science: Neochauliodes digitiformis sp. nov., Neochauliodes parasparsus sp. nov. and Neochauliodes sparsus sp. nov. A key to the species from Henan is presented.

Titimbera,a new genus of Orthocladiinae from South and Central America (Diptera: Chironomidae)

Titimbera n. gen. is erected based on the males of three new species from South and Central America: T. amazonica n. sp. from the Amazon region, Brazil; T. titi n. sp. from Venezuela and T. laselvensis n. sp. from Costa Rica. The combination of bare eyes and wing membrane; antenna without strong apical seta; scalpellate acrostichals in mid scutum; costa strongly extended; R₄₊₅ ending opposite to M₃₊₄; Cu₁ strongly curved to slightly sinuous; anal point sitting high on tergite IX, nearly parallel-sided with bluntly rounded apex; and club-shaped to subtriangular gonostylus with distinct heel will separate the genus from all other orthoclads.     

Two new species of the genus Boysidia from China,with a preliminary discussion of its geography (Pulmonata: Stylommatophora: Pupillidae)

Two species of the genus Boysidia Ancey, 1881 were reported as new to science, Boysidia(Boysidia) xianfengensis sp. nov. and B.(B.) xiaoguanensis sp. nov., while the distribution of the 23 species of Boysidia from China was discussed. The materials of the new species were collected from Hubei Province, China by authors. The shell of B.(B.) xianfengensis sp. nov. looks small(height 4.90 mm, diameter 3.10 mm), and has five apertural teeth: one large parietal tooth, one long columellar tooth, one small nipple-shaped upper palatal tooth, one large flake-shaped lower palatal tooth, one small infrapalatal tooth. The shell of B.(B.) xiaoguanensis sp. nov. looks small(height 3.55 mm, diameter 2.20 mm), and has four apertural teeth: one large parietal tooth, one long columellar tooth, one large flake-shaped upper palatal tooth, one slightly small flake-shaped lower palatal tooth. The type specimens of the new species are deposited in the Institute of Zoology, Chinese Academy of Sciences, China.     

A new genus and a new subgenus of cavernicolous beetles from Furong Jiang valley,southwestern China (Coleoptera: Carabidae: Trechinae)

A new genus and a new subgenus of semi-aphaenopsian trechine beetles are described from Furong Jiang valley in the bordering areas of Chongqing Shi (Municipality) and Guizhou Province, southwestern China: Deuveaphaenops Tian & Huang, n. gen. (type species: Deuveaphaenops qimenxicus Tian & Huang, n. sp. from Qimenxia Cave II, Wulong Xian, Chongqing) and Furongius Tian & Huang, n. subgen. (type species: Deuveaphaenops (Furongius) gelaophilus Tian & Huang, n. sp. from cave Xianmi Dong, Daozhen Xian, Guizhou). Deuveaphaenops probably belongs to the complex of Cathaiaphaenops, Qianotrechus, Guizhaphaenops and Sinotroglodytes.     

Spiders of the genus Lachesana and a new storenoid genus from Israel (Araneae: Zodariidae)

Zodariid spiders of two genera in Israel are revised. The genus Lachesana is represented by two species. Only one male of these was ever depicted while the females of both and their hitherto unknown retreats were never described. Pax gen. nov. has been erected to accommodate five species, some of which have formerly been placed in Slorena, Selamia or Habronestes . Diagnostic characters of the West Mediterranean Selamia and the Australian Habronestes are newly illustrated. No drawings of Pax libani and P. islamita were ever published; the male of the latter is described here for the first time. Pax palmonii sp. nov. and P. engediensis sp. nov. are described and affinities of all taxa are discussed. Illustrations, records of distribution and keys to the species are provided.
