Studies on the South African Clinidae. I. Description of a new species of Pavoclinus, and redescription of Gynutoclinus rotundifrons (Barnard)

ABSTRACT The South African species of Caecidae are revised on the basis of the material stored in the KwaZulu-Natal Museum (Pietermaritzburg, South Africa). Twenty species are recognized, 10 of which are described as new: Caecum austrafricanum, C. incisum, C. intortum, C. Knysnaense, C. leilae, C. lindae, C. maraisi, C. morgan, Parastrophia avaricosa and P. ornata. The lectotype of Caecum subquadratum Carpenter, 1859 is herein selected.

Six new species are described from South African waters: Nymphonella lambertensis, Achelia barnardi, Nymphon modestum, Propallene crassimana, Anoplodactylus unilobus, and Pycnogonum angulirostrum. Two other species, Ammothella indica Stock and Achelia spec. aff. australiensis (Miers), are recorded for the first time from South Africa. The genus Hannonia is synonymized with Tanystylum. Of the genus Queubus the hitherto unknown female is described; her anatomical details point to relationships with the Callipallenidae. Remarkable anatomical facts are mentioned in Propallene crassimana (numerous cement gland cones), and in Achelia barnardi and Tanystylum brevipes (both with a retractable proboscis).

A new species of Biton from the Kalahari is described. Some observations are made on the ctenidial hairs and the tarsal spines of Biton schreineri (Purcell) and its relationship with Broomiella lineata (Pocock). Comments are made on the distribution of Solpuga monteiroi Pocock and the systematic position of ‘Solpuga grindleyi n. sp.’ Brown.

Paramendax apicina Powell and Mendax attenuatispira Powell are referred to genus Triforis Deshayes; T. antepallaxa, T. blacki, and T. tui are described as new; and a species close to the South Australian Triforis epallaxa (Verco) is recorded from New Zealand waters. Paramendax Powell is transferred from the Cerithiopsidae to the Triforidae as a subgenus of Triforis. It is suggested that the Recent South African Cerithiella nonnitens Barnard is referable to Triforis.

The taxonomy of the poorly known estuarine crab genus Ilyograpsus Barnard, 1955, is revised. Five species are recognized in the genus: I. paludicola (Rathbun, 1909) from Southeast to South Asia, northeastern Australia and New Caledonia; I. rhizophorae Barnard, 1955 (type species) from the Red Sea and the western Indian Ocean; I. nodulosus Sakai, 1983, from southern Japan; I. vannini Sawada, Hosogi & Sakai, 2005 from Somalia; and I. daviei, new species, from Queensland, Australia. The four previously described species are rediagnosed. A new genus, Apograpsus, is established for the recently described species Ilyograpsus paantu Naruse & Kishino, 2006. The two genera are referred to the family Macrophthalmidae. Affi nities of the two genera to Enigmaplax Davie, 1993 and a hypothetical ancestor of Macrophthalmus proposed by Barnes (1967) are discussed.

Close examination of Orthoprotella mayeri K.H. Barnard, 1916 (sensu lato) which has been recorded from South Africa and New South Wales, Australia, revealed that there are two distinct species from Cape Province, South Africa and New South Wales, Australia, respectively. The present paper provides a redescription of O. mayeri K.H. Barnard, 1916 (sensu stricto) from South Africa and a description of O. berentsae sp. nov. from New South Wales, Australia. The two species can be identified based on the morphology of antenna 2, pereonites 6 and 7, and the uropods, although characteristic body somites of both species resemble other species.

Caddella croeseri sp. n. is described from the eastern Cape Province and Natal. A brief review of the distribution of known species of the genus is given, and a key for their identification. The genus Caddella was established by Hirst (1925) for a single species, C. capensis, from the Cape Province of South Africa. It was considered to be a member of the family Acropsopilionidae which then contained only a monotypic genus from Chile. In 1931 Lawrence created another monotypic genus, Oonopsopilio, and in 1935 synonymised it with Caddella and described one more species with a colour variety. Kauri (1961) redescribed C. capensis and C. africana but left the genus in Acropsopilionidae. In 1975 Shear, when revising the American forms of Caddidae, included the African species and assigned them to this family, recognising Acropsopilioninae as a subfamily. The three southern African species described to date are: .

A new gekkonid species, Afroedura hawequensis, is described from the south-western Cape (South Africa). The three species groups recognized in the genus are discussed.

ABSTRACT The scorpion fauna of East Africa, encompassing Burundi, Kenya, Tanzania, Rwanda, and Uganda, is more diverse than those of West and Central Africa, but a systematic survey has never been conducted and the distributions of its species remain poorly understood. A recent opportunity to examine two extensive collections of East African, and predominantly Kenyan, scorpions and new material acquired by the author permitted a reassessment of the fauna of the region. The present contribution, the first of several emanating from this research, comprises two parts. The first part presents a redefinition and revision of the scorpionid genus Pandinoides Fet, 1997, with a redescription of the type species, Pandinoides cavimanus (Pocock, 1888), a revalidation and redescription of Pandinoides militaris (Pocock, 1900), and a description of Pandinoides duffmackayi, sp. nov. Pending reassessment of the genera and subgenera of Pandinus, sensu lato, based on quantitative phylogenetic analysis, Pandinoides is restri...

Three South African Monhystera species, described by Joubert & Heyns (1980) (M. magnacdphala, M. gabaza and M. taaiboschiensis) are redeseribed and two of them figured in more detail, incorporating...

Abstract. Blacodatus szutkowskii, sp. nov. from South Africa is described, illustrated and compared with its relative — Blacodatus vertagus (Mulsant et Rey, 1859). A new generic concept of the previously monotypic Blacodatus is proposed. The distribution map is presented.

A revision of the south African genus Neopimus Özdikmen, Demir & Türkeş, 2008 is presented. Based on revision of the type and additional material, three species are recognised. The genus Neopimus is redescribed and all species are described or redescribed and illustrated, two of them for the first time: Neopimus capensis Janák, sp. nov., from Eastern Cape Province, South Africa and N. zulu Janák, sp. nov., from KwaZulu-Natal Province, South Africa. The distribution of the genus is mapped and a key of species is presented.

Afrotropical species previously assigned to Afroholopogon Londt, 1994 are revised. Following the reallocation of a species from Rhabdogaster Loew, 1858, the transfer of some species to Rhabdogaster and to a new genus, and the discovery of undescribed species, twenty-one species, arranged in two genera, are dealt with. Keys, and notes on taxonomy, distribution, phenology and biology, are provided. New genus: Ischiolobos (type species - Heteropogon holcocephaloides Lindner, 1955). New species: Afroholopogon: anassa (South Africa, Swaziland), argos (South Africa), aspros (South Africa), chirundu (Zimbabwe, South Africa), dasys (Oman, Eritrea), mauros (South Africa, Botswana, Namibia), melas (South Africa), pardosoros (South Africa), tanystylos (South Africa), uranopia (South Africa), xeros (Namibia, South Africa). Ischiolobos: mesotopos (South Africa), notios (South Africa). New combinations: Rhabdogaster meilloni Oldroyd, 1974 transferred to Afroholopogon; Heteropogon holcocephaloides Lindner, 1955 and Holopogon niveoscutum Hull, 1967 transferred to Ischiolobos. Heteropogon gracilis Engel & Cuthbertson, 1937 transferred to Rhabdogaster. New synonyms: Holopogon tomentosus Oldroyd, 1974 = Afroholopogon capensis (Lindner, 1961). Previously described species considered valid: Afroholopogon: africanus (Ricardo, 1925), capensis (Lindner, 1961), fugax (Loew, 1858), meilloni (Oldroyd, 1974), peregrinus (Engel, 1929), vumba (Oldroyd, 1974). Ischiolobos: holcocephaloides (Lindner, 1955), niveoscutum (Hull, 1967).

The parasitic isopod Cinusa tetrodontis Schioedte and Meinert, 1884, is the only species in Cinusa and has one known host, the evil-eye puffer fish, Amblyrhynchotes honckenii. The original Latin description contained many generic or family traits and thus the genus and species are redescribed. A complete revision of the genus was carried out, detailed illustrations of C. tetrodontis are provided and a lectotype designated and deposited in the Zoological Museum, University of Copenhagen.
