A New Species

Summary A new species, Emoleptalea nwanedi n. sp. is described from the intestine of Schilbe intermedius, the silver catfish or butter barbel, from the Nwanedi-Luphephe Dam in the Limpopo Province of South Africa. Fish were collected using gill nets where after they were euthanised and dissected. The parasites were sampled, fixed in 70 % EtOH and stained with Van Cleave’s haematoxylin. This species represents an addition to the African cluster of Emoleptalea species previously described and differs from the known species due to its unique size, equal size of oral and ventral suckers, position of ovary and seminal receptacle, number of vitelline follicles and their size, as well as the unique ciliated receptors on the wall of the acetabulum. This is the first record of this parasite from the silver catfish and from southern Africa.

Notes are provided on a collection of Afrotropical harvestmen (Opiliones: Palpatores: Phalangiidae) from the California Academy of Sciences. A new species of Rhampsinitus, R. conjunctidens n. sp., is described from Limpopo province of South Africa. Rhampsinitus flavobrunneus Staręga 2009 and R. silvaticus Lawrence 1931 are recognised as junior synonyms of R. nubicolus Lawrence 1963 and R. vittatus Lawrence 1931, respectively. Both R. conjunctidens and R. nubicolus are recognised as exhibiting strong male dimorphism with major males exhibiting larger body size and greatly enlarged chelicerae relative to minor males; minor males cannot be readily identified to species without examination of genitalia. A discussion is also provided on generic boundaries within Afrotropical Phalangiidae, and a generic key to males of the region is presented.

A New Species

In the course of revising the subfamily Urgineoideae of the Hyacinthaceae it became evident, based on molecular and morphological data, that some plants usually named ‘Drimia indica’ from northeastern South Africa represent rather an undescribed species of Vera-duthiea. This is the first record of this genus occurring in southern Africa. The new species (V. zebrina) was collected and illustrated some 50 years ago, but never validly published. We here provide data on its morphology, ecology, and distribution.

A New Species

The genus Acanthistius Gill, 1862 comprises ten putative valid species occurring in shallow warm-temperate waters of the Southern Hemisphere: South America (coasts of Ecuador, Peru, Chile, Brazil, and Argentina) southern Africa (Namibia and South Africa), southern Australia, New Zealand, Lord Howe, Norfolk, Kermadec and Easter, and Sala y Gómez islands. Two species: Acanthistius sebastoides (Castelnau, 1861) and Acanthistius sp are known from shallow waters of the east coast of South Africa (Heemstra and Randall, 1986). The latter taxon, previously known from a brief description of a single specimen, is here described from 23 specimens and named Acanthistius joanae. Acanthistius sebastoides is redescribed from 13 specimens and compared with A. joanae and species of Acanthistius known from South America and Australia. A neotype is designated for Serranus sebastoides Castelnau, 1861, as the two syntypes are apparently lost.

A New Species

A re-examination of the herbarium material has allowed to describe a new species, Corbichonia exellii, occurring in Southern Africa (Angola, Namibia and South Africa). C. exellii represents the third species in the genus. Morphological differences between all three Corbichonia species (C. decumbens, C. rubriviolacea, and C. exellii) are provided. The description of the genus is defined using the newly discovered characters (reproductive features). The taxonomy of all Corbichonia species (synonyms included) is provided, as well as maps for all species. The lectotypes of Orygia decumbens (basionym of Corbichonia decumbens) and O. mucronata (synonym of C. decumbens) are designated on specimens preserved, respectively, at BM and K. The genus Corbichonia, recently placed in Lophiocarpaceae, is markedly different from the core genus Lophiocarpus on the basis of embryological, morphological and carpological characters, and deserves further investigation concerning its taxonomic status.

A New Species

Gymnosporia swazica, a new restricted-range southern African species, is described and illustrated here. Known from only a few localities in Swaziland and bordering parts of South Africa (Mpumalanga and northeastern KwaZulu-Natal), G. swazica grows as an understorey shrub or small tree in forest, often among granite boulders. Diagnostic characters for G. swazica include chartaceous leaves, usually shorter than 25 mm, 3-valved capsules usually 6–7 mm long, which are smooth, green turning yellow, and a white aril partially covering the brownish seed. Its closest relative appears to be G. buxifolia (capsules rugose, mottled white-and-brown), one of the most widespread members of the genus in southern Africa, but it can also be confused with G. maranguensis (capsules red, 2-valved) and G. harveyana (capsules pink to red, 3-valved; aril orange, completely covering the seed).

A new species of the family Stenothoidae,Wallametopa cylindricasp. nov., is described from samples collected in 2015 in the Knysna Estuary, Western Cape, South Africa. This is the first record of the genusWallametopain South Africa, a genus now being represented by two species found in Africa, Madagascar and Australia.Wallametopa cylindricais closely related to the Australian and MadagascanW. cabonBarnard, 1974, from which it differs by having a distinct cylindrical elongation of the merus of gnathopod 1 in both sexes but more striking in males. Both the basis and the merus of gnathopod 2 are also acutely produced postero-distally. The palmar margin of the propodus of gnathopod 2 in males is strongly, irregularly incised and with a deep, broad excavation (larger male). The dactylus reaches the whole length of the propodus and is densely setose on the inner margin.

Cymbastela sodwaniensis sp. nov. (order Halichondrida: family Axinellidae) is described from the subtropical waters of Sodwana Bay on the north-east coast of South Africa. The genus was previously unknown from southern Africa or the western and eastern parts of the Indian Ocean. This record represents the westernmost extent of this predominantly Indo-Pacific to Australasian genus. This new species record brings the number of Cymbastela species described to a total of nine.

AbstractA new species, which may already be extinct, of flightless Trox, T. youngai sp.n., is described based on specimens collected 30 years ago from a now severely transformed area in South Africa. It is one of seven members of the natalensis-group of Trox species. All have very localised distributions in small fragments of once considerably larger habitats along the greater eastern escarpment and the coastal edge of southern Africa. is description brings the total number of endemic flightless Trox in the region to 14. A key to the species in the natalensis-group is provided. Furthermore, pronotal and elytral features of diagnostic value are tabulated to aid in the identification of members of this group. All species are illustrated by photographs of habitus and male aedeagi. A map is provided showing the distributions for each of them.
