AbstractA new species of ascaridoid nematode, Hysterothylacium anguillae sp. n. (family Anisakidae), is described based on specimens recovered from the stomach and intestine of the giant mottled eel Anguilla marmorata Quoy et Gaimard from the Mngazi River, South Africa, collected in March–April 2011. It is characterized mainly by poorly developed lateral alae, a very short intestinal caecum and a long ventricular appendix, spicules 1.11–2.14 mm long (representing 5.2–5.8 % of body length), number of caudal papillae (19–21 pairs of preanals, 2 adanals and 5 postanals), presence of a median precloacal papilla (= ventromedian organ), tail tips of both sexes covered by minute spines, and by the shape and structure of lips. This is the first nominal species of Hysterothylacium described from an African freshwater fish and the second species of this genus reported from freshwater eels of the family Anguillidae. The following Indian congeneric species are considered species inquirendae: Hysterothalacium aetobathum Lakshmi, 2005, H. carutti Lakshmi, Rao et Shyamasundari, 1993, H. channai Lakshmi, 1995, H. fossillii Lakshmi, 1996, H. japonicum Rajialakshmi, 1996, H. kiranii Lakshmi, 1993, H. longicaecum Lakshmi, Rao et Shyamansundari, 1993, H. narayensis Lakshmi, 1997, H. nellorensis Lakshmi, 1996, H. neocornutum Rajialakshmi, Rao et Shyamasundari, 1992 and H. punctati Lakshmi, 1995. Of them, H. japonicum and H. neocornutum are transferred to Iheringascaris Pereira, 1935 as I. japonica (Rajialakshmi, 1996) comb. n. and I. neocornuta (Rajialakshmi, Rao et Shyamasundari, 1992) comb. n.

A New Species

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.

A new species of the spider family Telemidae from South Africa, Cangodercesglobosa sp. n., is diagnosed, described and illustrated. This is the second species of the family to be recorded from the country. Consistent with the habits of most Afrotropical telemids, C.globosa sp. n. was collected by sifting leaf litter in forests.

AbstractA new anisakid nematode, Hysterothylacium liparis sp. nov., is described from the intestine and stomach of the fish, Liparis tanakae (Gilbert et Burke, 1912) (Scorpaeniformes, Liparidae), a fish endemic to the Yellow Sea, China. The new species can be distinguished from the congeners by the absence of lateral alae, the length of the intestinal caecum (1.94–3.35 mm, 58.84–82.47% of oesophageal length), the number and arrangement of the caudal papillae (20–29 precloacal subventral pairs, 1 adcloacal pair and 4 postcloacal pairs), the size of the spicules (1.94–3.74 mm, 4.85–7.30% of body length) and the morphology of the tail tip. This is the first species of adult ascaridoid nematodes to be reported from fishes of the family Liparidae in northern China.

AbstractNumerical analyses were performed on three nominal species of the family Tristiridae. The synonymy existing between Philippiacris Liebermann and Elasmoderus Saussure is corroborated. Philippiacris rabiosus Liebermann is placed in synonymy under Elasmoderus lutescens (Blanchard) as a morphotype. The new combination Elasmoderus wagenknechti (Liebermann) is proposed, and a new species from Chile, Elasmoderus minutus, is erected.

A New Species

Myxinidocotyle eptatreti n. sp. is described from the skin of the sixgill hagfish, Eptatretus hexatrema collected for exhibition at the Two Oceans Aquarium in Cape Town, South Africa. The new species is the first acanthocotylid described from South Africa and differs significantly from the only two known Myxinidocotyle species by the morphology of the sclerotised male copulatory tube and the presence of a diverticulated intestinal caecum. The subfamily diagnosis is amended to include a single seminal receptacle, found within the anterior concave portion of the ovary and excludes the vaginal seminis receptaculum which is considered the seminal vesicle. The vagina travels ventrally over the seminal vesicle and does not fuse with it bilaterally as originally proposed by Malmberg & Fernholm (1989). Myxinidocotyle spp. possess 8 or 9 testes. The proximal male accessory gland reservoirs are connected by an intricate network of fine ducts to the field of extensive male accessory gland cells extending along the length of the body proper. Observations on the locomotion and attachment of live worms in vitro are discussed and the presence of adhesive secretions is confirmed for the haptoral glands and anterior glands.

A New Species

In the present study, we described and illustrated Aplectana minaensis n. sp. (Ascaridida: Cosmocercidae) from the intestinal caecum of Amphisbaena alba Linnaeus (Squamata: Amphisbaenidae). Aplectana minaensis n. sp. is the 5th species described in Brazilian hosts and 58th species assigned to the genus. This species differs from its congeners by a set of unique characters in males: the presence of one unpaired precloacal papilla and gubernaculum, the papillae pattern (4+1:2:6) and total number (12+1), and the size of spicules (400–605 µm). Among the Aplectana species with an unpaired precloacal papilla and gubernaculum, only A. minaensis n. sp. and A. nebulosa Gomez, González & Sanabria, has less than 20 pairs of caudal papillae. However, these species differ in the number of caudal papillae in males (12+1 vs. 13–14+1, respectively); the number and arrangement of post cloacal papillae (6 pairs: 1st to 4th pairs ventral, 5th pair laterodorsal, 6th pairventral vs. five pairs: 1st and 2nd ventral, 3rd lateral, 4th ventral, 5th lateral); and by the size of spicules (413–600 vs. 85–126 µm).
