Two earthworm species from central Mexico are described: Protozapotecia acaxetlensis sp. nov. and Protozapotecia oya-metlensis sp. nov. Delimitation of species was supported by morphological and molecular evidence. The two new species differ from the other species of Protozapotecia by the position of the prostates in segments 18 and 20. This morphological characteristic relates them to the genus Diplocardia, from which they differ by the presence of two gizzards separated by a muscular septum (Protozapotecia), instead of two gizzards fused as one, separated by a thin membranous septum in intersegment 5/6 (Diplocardia).

Two New Species

Abstract The genus Barretonus Roudier, 1958 is a genus endemic to Macaronesia, described from the archipelago of Madeira where four species are known to date. In this study, two new species of Barretonus, B. auarita García & Oromí sp. nov. (from La Palma, Canary Islands) and B. daute García & Andújar sp. nov. (from Tenerife, Canary Islands), are described based on morphological and molecular evidence (mtCOI), and additional notes on their biology and ecology are provided. Morphology of the new species is compared with the other representatives of the genus, and their phylogenetic relationships with a Barretonus representative from Madeira and species from additional genera within the Cossoninae are shown. This work increases the number of species of the genus Barretonus from four to six anophthalmous or microphthalmous species with an endogean lifestyle, and incorporates the Canary Islands into its Macaronesian range of distribution.

Two new species of Terebrasabella Fitzhugh & Rouse, 1999 are described from eastern Australia. Terebrasabella hutchingsae sp. nov., was found from preserved coral rock debris collected in 1977 on the outer Barrier Reef near Lizard Island, Queensland. Terebrasabella fitzhughi sp. nov., was found alive in burrows in and among spirorbin serpulid tubes on intertidal rocks in Tasmania in 1996. Both species were found in mucoid tubes, and brood their young in a manner similar to the only other described species of Terebrasabella, T. heterouncinata Fitzhugh & Rouse, 1999. Terebrasabella hutchingsae sp. nov., is exceptional as it possesses a type of thoracic neurochaetal uncinus different from the other two species, and which is similar to the notochaetal acicular “palmate hook” seen in Caobangia. Descriptions of both species are given, and the diagnosis for Terebrasabella is emended. Larval and chaetal morphology and relationships among of the three known Terebrasabella spp. are discussed.

Two new species of South African Syllidae of the genusSyllisLamarck, 1818 are described.Syllis unzimasp. nov. is characterized by having unidentate compound chaetae with long spines on margin, a characteristic colour pattern and its reproduction by vivipary. Vivipary is not common among the polychaetes, but most representatives occur in the family Syllidae Grube, 1850 (in five otherSyllisspecies, two species ofDentatisyllisPerkins, 1981 and two species ofParexogoneMesnil & Caullery, 1818).Syllis unzimasp. nov. differs from the other viviparous species in having large broods (>44 juveniles) which develop synchronously. Development of the juveniles is similar to that of free-spawningSyllisspecies, but the appearance of the first pair of eyespots and the differentiation of the pharynx and proventricle occur later inS. unzima.Syllis amicarmillarissp. nov., is characterized by having an elongated body with relatively short, fusiform dorsal cirri and the presence of one or two pseudosimple chaeta on midbody parapodia by loss of blade and enlargement of shaft.Syllis unzimasp. nov. was found in high densities on culturedHolothuria scabraJaeger, 1833 with single specimens found on a culturedCrassostrea gigasThunberg, 1793 and on coralline algae, respectively, whileS. amicarmillariswas found mainly in sediment outside an abalone farm and less frequently on culturedHaliotis midaeLinnaeus, 1758. We discuss the possible benefits of the association withH. scabratoS. unzimasp. nov.

The identity of the poorly known bagrid catfish Pseudomystus moeschii (Boulenger, 1890) is clarified and the species redescribed. Two new species of closely related bagrid catfishes are also described: Pseudomystus carnosus from the Way Seputih River drainage in the province of Lampung in the southern tip of Sumatra, and P. fumosus from the Pahang River drainage in eastern Peninsular Malaysia. Pseudomystus carnosus, P. fumosus and P. moeschii can be distinguished from congeners in having an enlarged posterior process of the post-temporal, presence of long hair-like epithelial projections on the skin and long tubular extensions of the sensory pores. Pseudomystus carnosus differs from the other two species in having a pointed (vs. rounded) tip of the nuchal shield, while P. fumosus differs from the other two species in having very well developed procurrent caudal rays which are sinuously curved along the anterior edges (vs. less developed procurrent caudal rays that slope evenly along the edges). A lectotype is designated for P. moeschii.

A New Species

The genus Cicadulina was established in 1926 (Bull. Ent. Res. 17, p. 43) to hold a new species, C. zeae, China, injurious to maize in Kenya Colony. Later (Bull. Ent. Res., 19, 1928, p. 66) it was shown that Balclutha mbila, Naude, recorded as transmitting the virus of streak disease of maize in Natal, also belonged to this genus, and two new species C. arachidis and C. similis were described from the Gambia, where they were reported as injurious to ground-nut and suspected of transmitting the virus of the rosette disease of that plant. Since that time Dr. H. H. Storey of the Amani Research Station has been investigating the possibility of transmission of the streak virus of maize by C. zeae. In attempting to breed strains capable of transmission of the disease certain crosses were made which showed conclusively that he was dealing with two distinct species. These species he was able to separate on the colour pattern of the abdomen. Dr. Storey has now sent to me material of both these species and a study of the genitalia corroborates his finding. One, of course, proved to be C. zeae, the other is new and I therefore propose to dedicate it to the discoverer.

Two new species of the genus Crenicichla from the upper rio Uruguay basin are described, Crenicichla hadrostigma and C. empheres. Both are included in the C. missioneira species group along with C. missioneira, C. minuano, C. tendybaguassu, C. igara, and C. jurubi, all occurring in the upper and middle rio Uruguay drainage. Crenicichla hadrostigma is distinguished by the conspicuous ocellated posttemporal blotch, absence of a humeral spot and lateral band, and the presence in males of nine to 16 narrow vertical bars extending from the dorsum to a horizontal line that passes through the lower edge of pectoral axilla. Crenicichla empheres is distinguished from the other species of the missioneira-group by the presence of six to eight horizontally elongate dark blotches along the middle portion of the body, slightly below the upper lateral line, absence of a lateral band, presence in males of numerous dark and irregularly arranged spots on nape, back, and sides of body, and isognathous mouth. A key to the species from rio Uruguay basin is presented.

Four species ofLaonice(Annelida: Spionidae) were collected from the lower bathyal depths (3300–3700 m) in the Whittard Canyon, NE Atlantic. Two are herewith described as new species:Laonice whittardensissp. nov. andLaonice nataesp. nov. The other two areLaonice blakeiSikorski & Jirkov, 1988 andLaonice magnacristataMaciolek, 2000.Laonice whittardensishas genital pouches appearing from chaetiger 3, prostomium free of peristomium and bidentate hooks.Laonice nataebelongs to the subgenusAppelloefianov. with prostomium distinct from the peristomium, more than two vertical rows of capillaries in several anterior chaetigers, genital pouches present on a limited number of segments or totally absent. However, the absence of pronounced anterior widening of the body together with anterior branchiae, which are remarkably (nearly twice) longer than the notopodial postchaetal lobes, the narrow lanceolate notopodial postchaetal lobes, the pronounced pointedness of all postchaetal lobes (both notopodial and neuropodial) in the anterior half of body at least, and absence of genital pouches and the size of the body all distinguishL. nataefrom other species belonging to this subgenus. An identification key to all nine known deep-water (>400 m depth)Laonicespecies in North Atlantic is given and four previously recognized sub-generic groups are formally named:Laonice, Sarsianasubgen. nov.,Appelloefiasubgen. nov.,Norgensiasubgen. nov.
