AbstractThree nematode species of Cithariniella (Pharyngodonidae), C. citharini, C. khalili, and C. gonzalesi, were recorded from the recta of squeaker (Mochokidae: Siluriformes) and citharinid (Citharinidae: Characiformes) fishes from Senegal, West Africa. Morphological characteristics obtained by scanning electron microscopy (form of oral aperture and cephalic papillae, presence of lateral alae, distribution and form of cloacal papillae, simple or paired papillae on tail of males, eggs with numerous long filaments on each pole in females) correspond well to the generic diagnosis and represent species differences. The shape and size of the cephalic papillae and lips were identified as a new determination feature. C. gonzalesi is reported for the first time from Senegal and its host, Paradistichodus dimidiatus, represents a new host record. A tentative simple key for differentiating C. citharini, C. khalili, C. gonzalesi and C. petterae is provided based upon these results.

The genus Malgacheliodes is recorded in South Africa for the first time. Malgacheliodes martensi spec. nov. is described from soil of Hogsback State Forest, Eastern Cape Province. Adults of the new species differ from those of Malgacheliodes guillaumeti by the presence of ribs and furrows in the aggenital region, bacilliform leg tracheae, rounded ventral keel on leg I femur and four pairs of notogastral setae (h1 absent); while its tritonymph differs from that of M. guillaumeti by the presence of five pairs of gastronotic setae (c1 absent). The generic diagnosis of Malgacheliodes is updated. The differences in morphology of the tritonymphal instar in Malgacheliodes and other genera of Licnodamaeidae are presented.

A New Species

The crab spider genus Tarrocanus Simon, 1895 currently includes two species: T. capra Simon, 1895 and T. viridis Dyal, 1935. Recent field work revealed the presence of a new species, providing an opportunity to review the genus. The new species is described as T. jaffnaensis sp. nov. Furthermore, the male of T. capra is described for the first time, and taxonomic notes on Alcimochthes Simon, 1885 and Domatha Simon, 1895 are given, both presumably being close relatives of Tarrocanus. Tarrocanus viridis Dyal, 1935 is considered as nomen dubium.

AbstractSpecies of the oribatid mite genus Tegeocranellus from North and Central America are discussed, and immatures are described for the first time. Six new species are described and keyed: Tegeocranellus alas from Costa Rica, T. barbarae from Alabama, Mississippi, and Florida, T. kethleyi from Alabama and Mississippi, T. mississippii from Louisiana and Texas, T. muscorum known from Ontario to Florida, and T. mediolamellatus from Guatemala. Descriptions of T. alas, T. barbarae, T. mediolamellatus, and T. muscorum are based on adults and immatures, and those of the other two species on adults only. I expand the generic diagnosis to include information on the apheredermous, plicate immatures, and present a character analysis hypothesizing that the monogeneric family Tegeocranellidae is a member of the Ameronothroidea, closely related to Selenoribatidae and Fortuyniidae.

The oribatid mite genus Gephyrazetes (Oribatida, Mochlozetidae) is recorded for the first time in the Ethiopian region; one new species is described from soil and litter of Korup National Park in Cameroon. Gephyrazetes umukusumae sp. nov. differs from G. fasciatus Hirauchi, 1999 by the larger body size, truncate lamellar cusps, setiform bothridial setae, very small notogastral porose areas, paraanal position of adanal lyrifissures, presence of four pairs of genital setae and tuberculate lateral parts of prodorsum, and absence of dorsosejugal and sublamellar porose areas. Revised generic diagnosis and the data on distribution and ecology of Gephyrazetes species are presented.

The genus Kalloia (Oribatida, Carabodidae) is recorded in the Oriental region for the first time. A new species — Kalloia gerdweigmanni n. sp. — is described from litter of oil palm plantations and jungle rubber agroforests from Sumatra, Indonesia. It differs from Kalloia simpliseta Mahunka, 1985 by the presence of a transverse ridge in the mediodistal part of the lamellae, translamella and two thick, diagonal, convergent ridges forming a triangular structure in the medioanterior part of the notogaster, and by the localization of notogastral setae da, dm, la, lm, lp and h1. The generic status of Kalloia is discussed and supported. Kalloia mahunkai Pérez-Íñigo and Baggio, 1989 and Machadocepheus foveolatus Mahunka, 1978, which were considered representatives of Kalloia, are removed from this genus and combined preliminarily in Gibbicepheus. Revised generic diagnosis and data on ecology and distribution of known species of Kalloia are presented.

Crab Spiders

Urbanization has a great impact on the diversity of living organisms. Spiders, for example, have been shown to respond negatively (some orb weaving species) and positively (ground dwelling species) to urbanization. The effects of urbanization on crab spiders (Thomisidae) (sit-and-wait predators that generally ambush their prey on flowers and leaves) are not sufficiently known. This paper describes the Thomisidae community that inhabits green patches in a temperate Neotropical city, Cordoba, Argentina, and its surroundings, and ascertains whether there are differences in species richness, abundance and composition between urban and exurban sites. Samples were collected from 30 sites during the summer and spring of 2013 and 2014, using the garden-vacuum method. We compared the abundance, richness and composition of Thomisidae among three habitat categories (urban, suburban and external). Seven species in three genera, Misumenops, Wechselia and Tmarus, were detected. Misumenops was the most abundant genus in Córdoba, and Tmarus elongates Mello-Leitão, 1929 was collected in Argentina for the first time. The abundance, richness and composition of thomisid spiders did not differ between habitat categories, indicating that urbanization does not have a negative effect on the communities of these spiders in open green spaces. Site variability, on the other hand, does, suggesting that local factors may be more relevant than broad-scale factors to explain community patterns in this family.
