A New Species

Cottunculus tubulosus n.sp. is described from one specimen caught in the summer of 2004 in the Northeast Atlantic, at about 2000 m depth in the Mid Atlantic Ridge. The species is characterised by a slender body, a long head, large pointed cranial spines, large bony tubules along the lateral line, prominent dermal prickles along the back, dorsal and anal fins set far posterior, a short caudal peduncle, and no banded colour patterns. From morphological characters, the species seems closely related to the South African species C. spinosus.

Two New Species

Two species of Aphanarthrum collected from dead spurges of Euphorbia in South Africa are illustrated and described as new to science. They represent the first records from the southern parts of Africa and thus significantly extend the known distribution of the genus. Analyses of the phylogenetic relationships of the species of Aphanarthrum and Coleobothrus based on molecular and morphological characters yielded a relatively well supported but nevertheless distant sister relationship between the two South African species. Their relationship to other Aphanarthrum remains uncertain and revealed deep divergence, indicative of a rather ancient origin. The peripheral distribution of the South African species and the broad availability of suitable host plants throughout the continent suggest that more species remain to be discovered in this region.

AbstractThe New World genus Erythrothrips is redefined and a key to the species provided. A new genus and species, Erythridothrips cubilis, is described from Australian tropical rain-forest. The South African genus Audiothrips is withdrawn from synonymy with Erythrothrips and a new species, A. senckenbergiana, is described. The sole African species in the American genus Stomatothrips is transferred to the African genus Allelothrips. The relationships of these taxa are discussed, together with reasons for questioning the validity of the tribe Orothripini.

A New Species

Strongylodesma aliwaliensis, a new species of Strongylodesma L vi, 1969 (Porifera; Demospongiae; Poecilosclerida; Latrunculiidae) is described from the subtropical waters along the east coast of South Africa. This species differs from both the type species, Strongylodesma areolata L vi (1969) and the two known South African species, S. tsitsikammaensis Samaai and Kelly (2003) and S. algoaensis Samaai and Kelly (2003), in the structures of the choanosome, length and morphology of the strongyles and colouration. The choanosome of S. aliwaliensis sp. nov. is divided into thick convoluted tracts, which may or may not form discrete chambers, the latter character first observed in Tsitsikamma favus Samaai and Kelly (2002). This structure however, is not unique for Tsitsikamma (Family Latrunculiidae), as evidence also shows that species of Zyzzya (Acarnidae) have a choanosomal structure reminiscent of that of Tsitsikamma (Samaai and Kelly, 2002). The choanosomal architecture of S. aliwaliensis sp. nov however, differs considerably from Tsitsikamma favus Samaai and Kelly (2002) in that the choanosome lacks the discrete honey comb-like chambers as found in T. favus Samaai and Kelly (2002). Thus, the convoluted tract morphological character as observe in Strongylodesma aliwaliensis sp. nov, Tsitsikamma and Zyzzya holds no phylogenetic weight; it is cross taxon like the axial compression of Axinellidae, Raspailiidae, and the desmas of Lithistids and therefore cannot be used as a character for inclusion of this new species within either Tsitsikamma or Zyzzya. The inclusion of the new taxon within Strongylodesma is strongly supported based on the presence of strongyles, the fungiform areolate porefields and structure of the ectosomal layer. Preliminary chemical analysis of the sponge has confirmed the presence of several pyrroloiminoquinone products, including makaluvamine I.

Eurytoma erythrinae Gates and Delvare, new species, is described and illustrated. This species was reared from fieldcollected galls on Erythrina spp. (Fabaceae) induced by Quadrastichus spp. (Hymenoptera: Eulophidae), in Tanzania, Ghana, and South Africa. It is compared with very similar African species, Eurytoma radicicola Risbec. Afrotropical species classified in Eurytoma are reviewed and twenty-seven new combinations are proposed: Aximopsis acaciacola (Hedqvist) comb. n., A. caryedocida (Rasplus) comb. n., A. lamtoensis (Rasplus) comb. n., A. mateui (Hedqvist) comb. n., A. mimosarum (Rasplus) comb. n., A. obocki (Risbec) comb. n., A. oryzivora (Delvare) comb. n., A. saharensis (Hedqvist) comb. n., A. senegalensis (Risbec) comb. n., A. tropicana (Risbec) comb. n., Bruchophagus conapionis (Rasplus) comb. n., Fronsoma ellenbergeri (Risbec) comb. n., Gibsonoma amborasahae (Risbec) comb. n., G. aphloiae (Risbec) comb. n., G. bararakae (Risbec) comb. n., G. eugeniae (Risbec) comb. n., G. mandrakae (Risbec) comb. n., G. pauliani (Risbec) comb. n., G. plectroniae (Risbec) comb. n., G. tavolae (Risbec) comb. n., Philolema arachnovora (Hesse) comb. n., P. arnoldi (Waterston) comb. n., P. bambeyi (Risbec) comb. n., P. braconidis (Ferrière) comb. n., and P. syleptae (Ferri_re) comb. n., Phylloxeroxenus cressoni (Howard) comb. n., and Sycophila plectroniae (Risbec) comb. n. Lectotypes are designated for ten species: Eurytoma perineti Risbec, E. radicicola Risbec, E. toddaliae Risbec, Gibsonoma amborasahae (Risbec), G. aphloiae (Risbec), G. eugeniae (Risbec), G. mandrakae (Risbec), G. pauliani (Risbec), G. tavolae (Risbec), and P. bambeyi (Risbec). We also provide a checklist of Afrotropical species that are or were classified in Eurytoma and tabulate the known host/associations of these species with references.

Platynereis Dumerilii

The perceived cosmopolitanism of polychaete worms could be an artefact of historical factors such as poor original species descriptions, lack of type material and the European taxonomic bias, to name a few. Thus, it is possible that several cosmopolitan species hide complexes of cryptic and pseudocryptic species. Two putative cosmopolitan species, Platynereis dumerilii and Platynereis australis, collected in South Africa were investigated here (1) to determine whether the South African taxa are conspecific with the morphologically identical taxa from France and New Zealand (the respective type localities of P. dumerilii and P. australis), (2) to compare the South African species morphometrically to determine whether their morphological characters are reliable enough to separate them, and (3) to investigate whether these species have geographically structured populations along the coast of South Africa. Molecular data (COI and ITS1) confirm that P. dumerilii and P. australis do not occur in South Africa. Instead, the South African taxon formerly thought to be Platynereis dumerilii is new and is described here as Platynereis entshonae, sp. nov.; the identity of the other South African species is currently unresolved and is treated here as Platynereis sp. Surprisingly, Platynereis massiliensis (type locality: Marseilles) nested within the South African Platynereissp. clade but, since it is part of a cryptic species complex in the Mediterranean, the name is considered doubtful. Morphological characters traditionally used to define these South African Platynereis species are not reliable as predefined morphological groupings do not match phylogenetic clades and principal component scores revealed no separation in morphological characters that could distinguish between them. Haplotype networks and phylogenetic trees revealed that P. entshonae, sp. nov. and Platynereis sp. have geographically structured populations along the South African coast. http://zoobank.org/urn:lsid:zoobank.org:pub:6E36A210-9E48-430F-8A93-EDC27F0C5631

A new species of Obuloides, Obuloides crinitus sp. nov., is described based on females and males collected from the galls and twigs of Grewia occidentalis (Tiliaceae) in South Africa. Obuloides crinutus is closely related to O. namibiensis and O. rajamohani but can be distinguished by the finely granulated shields, a character that no other species of this genus has. Another notable difference is the length of prodorsal setae v2, which are longer and more strongly serrated compared to the other species of this genus which have very short and mostly smooth setae. Males of this species lack setae d1. A key to known species is provided.

Two new species of the genus Paragus Latreille, 1804 are described from the Republic of South Africa: Paragus longipilus Tot, Vujić et Radenković sp. nov. and Paragus megacercus Tot, Vujić et Radenković sp. nov. These new species belong to the subgenus Pandasyopthalmus Stuckenberg, 1954a. Paragus longipilus sp. nov. is a member of the P. jozanus group, whereas Paragus megacercus sp. nov. belongs to the P. tibialis group. The taxonomic status of Paragus chalybeatus Hull, 1964 is revised and proposed as synonym of Paragus punctatus Hull, 1949. Additionally, an identification key to males of the South African species of Paragus is provided. Results of the present study confirm a significant level of endemism of Paragus in the Afrotropical Region (12 out of 29).
