Species Descriptions

The genus Campylaimus is a broadly distributed but relatively uncommon genus of marine and brackish nematodes with 20 nominal species and one nomen nudum. Many species descriptions and redescriptions are based on very few (single) individuals, which limits our understanding of inter- and intra-specific variability and morphology-based species boundaries. Two new species were found in the Skagerrak off the west coast of Sweden. Campylaimus triclados sp. n. is characterised by body 0.59–0.69 mm long; cuticle without longitudinal striation; anteriormost edge of the amphid anterior to the oral opening; dorsal limb of the amphid equal to 1.6–2.5 labial region diameters in male, 1.9 labial region diameters in female; ventral limb of the amphid extends towards anterior part of the intestine in male and midpharynx in female, 4.3–5.5 times the length of the dorsal limb in male and 2.2–2.8 times the length of the dorsal limb in female; ventral limb of the amphid is as wide as the dorsal limb; interamphideal space extends further than the posterior end of the dorsal limb but not reaching the posterior end of the ventral limb; secretory-excretory pore opens posterior to the cardia; spicules 19–24 µm long; two precloacal supplements; tail equal to 4.3–5.6 anal body diameters in length, with conoid terminal part. Campylaimus longispiculus sp. n. is characterised by body 0.56–0.65 mm long; cuticle without longitudinal striation; anteriormost edge of the amphid anterior to the oral opening; dorsal limb of the amphid equal to 1.8–2.1 labial region diameters in male; ventral limb of the amphid extends towards anterior part of the intestine in male, 2.8–3.5 times the length of the dorsal limb in male; ventral limb of the amphid is as wide as the dorsal limb; interamphideal space absent; secretory-excretory pore opens posterior to the cardia; spicules 28–35 µm long; two precloacal supplements; tail equal to 4.9–5.3 anal body diameters in length, with clavate terminal part. In addition, following nine species are new records for the fauna of Sweden: Campylaimus amphidialis, C. inaequalis, C. lefeverei, C. minutus, C. orientalis, C. rimatus, C. siwaschensis, C. striatus and C. tkatchevi.

Species Descriptions

LacydoniaMarion & Bobretzky in Marion, 1874 is the only known genus in Lacydoniidae Bergström, 1914, which is composed of small polychaetes scarcely sampled. Studies on the biology and ecology of this group are rare and most species descriptions are based on one or a few specimens. There are 13 nominal species from different parts of the world. We revise herein the morphological characters used for species description on the basis of a lacydoniid assemblage collected in Campos Basin, Southern Brazil. Material was obtained in two sampling campaigns during the Project Habitats/Petrobras – Heterogeneidade Ambiental da Bacia de Campos, coordinated by CENPES/Petrobras. Lacydoniids were collected from the continental shelf, canyons and slope, at depths from 25 to 2500 m. This polychaete family is recorded for the first time in Brazilian waters, three new species are described and all others are new records to the South Atlantic. The new species areLacydonia anapaulaesp. nov.,L. brasiliensissp. nov. andL. jackisp. nov. Newly recorded species areL. cirrata(Hartman & Fauchald, 1971),L. laureciLaubier, 1975,L. mirandaMarion & Bobretzky in Marion, 1874,L. oculata(Hartman, 1967) andL. cf.papillataUschakov, 1958. An updated key to all described species ofLacydoniais included.

During a series of zooplankton surveys carried out from 2001 through 2005 off the coast of the state of Bahia, Brazil, 98 individuals of monstrilloid copepods were collected. These belong to five species (Monstrilla grandis, Cymbasoma cf. longispinosum, Cymbasoma cf. rigidum, Cymbasoma gracilis, and Cymbasoma quadridens). The first three are recorded for the first time in the Bahia coastal region. The geographical range of C. quadridens is expanded to the Brazilian northeastern coast. The results presented herein increase to nine the number of nominal species of Monstrilloida known from off Bahia; the environmental diversity of Caravelas Channel with highly productive areas and coral reef zones harbor an abundant and diverse monstrilloid fauna that should be surveyed in more detail.

We examined 308 specimens of the Indo-Pacific blenniid Omobranchus punctatus deposited in four museum collections, and analyzed data on their collection locations to assess its invasion on the Atlantic coast of Central and South America. This species occurs in shoreline estuarine and marine habitats in the Indo-West Pacific. Previous sampling and recent records in the Tropical West Atlantic from 1930 to 2004 produced 20 records for: Panamá, Colombia, Venezuela, Trinidad and Brazil. In this work, we provide data on 17 new records for the Gulfs of Venezuela and Paria in Venezuela, as well as four records for Maranhão and Pará states in NE Brazil. The temporal pattern of collections (1930 - 2009) and the proximity of most localities to ports and zones of ship traffic indicate that O. punctatus was initially introduced to the Atlantic by ships travelling from India to Trinidad. Within Brazil the introduction is linked to shipping connected to petroleum platforms. In Maranhão and Pará the introduction may have occurred as a result of fish sheltering in fouling on hulls of ships moving between ports around the mouth of the Amazon River. Alternatively, the spread of this species along of the American coast may reflect the expansion of the range of O. puntactus through larval dispersal in northward flowing currents. We recommend monitoring of this introduced species, and studies of its ecology in West Atlantic areas.

This is the first account of earthworms from the Gamba Complex of Protected Areas, a highly biodiverse coastal area ofequatorial Africa. We describe five new species of Dichogaster Beddard, 1888: Dichogaster (Diplothecodrilus)moussavoui sp. nov., D. (Diplothecodrilus) tchignoumbai sp. nov., D. (Diplothecodrilus) tobii sp. nov., D.(Diplothecodrilus) alonsoi sp. nov., and D. (Dichogaster) gambaensis sp. nov.; report several more taxa for which thematerial was not adequate to serve as the basis for new species descriptions, and present new records of several exoticspecies. Coastal Gamba is now known to have ten indigenous species and four introduced species, some of which areknown invasives. Characteristics shared by several Gamba Dichogaster conflict with characters used to define subgenera of Dichogaster, indicating that additional data are needed to resolve relationships within this large taxon.

Taxonomic Descriptions

The Mexican Pacific has been the focus of several research expeditions, with 90 species of hydromedusae and more than 200 species of hydroids recorded for the region. However, only a few of these reports include taxonomic descriptions, hindering inferences of the phylogenetic relationships, species boundaries, and diversity of Hydrozoa in Mexican waters. In this study, we present detailed and illustrated descriptions of new records of hydromedusae and hydroids for La Paz Bay, Gulf of California. We found a total of 16 species comprising 15 genera, with three new records for the Gulf of California (polyps of Antennella secundaria, Bimeria vestita, and Ventromma halecioides), two new records for the Mexican Pacific (medusa of Clytia linearis, polyp of Halopteris violae), and we redescribe Obelia tenuis. We show that the diversity of Hydrozoa in the Mexican Pacific is likely underestimated, and we emphasize the importance of taxonomic and systematic studies of hydroids and hydromedusae in Mexico.

Abstract A checklist of Schistonchus collected from Ficus spp. in Australia and stored in the Waite Nematode Collection at the University of Adelaide is presented. Within Australia, Schistonchus contains 12 morphospecies and four nominal species, based on a combination of the following characters: body shape when heat-relaxed, position of excretory pore, length of post-uterine sac, spicule form, and number and position of caudal papillae. Up to four morphospecies of Schistonchus have been collected from one species of Ficus and, in several cases, one morphospecies of Schistonchus has been collected from more than one host fig species. A phylogenetic tree based on D2/D3 sequences showed that Australian collections of Schistonchus fall into two clades, suggestive of endemic and introduced lineages with host switching. Schistonchus aculeata sp. n. is described from F. aculeata and F. opposita and differentiated from other species of Schistonchus by having the excretory pore opening near the lips, a short post-uterine sac, rosethorn-shaped spicules, arcuate gubernaculum or thickening of dorsal wall, amoeboid sperm, and three pairs of caudal papillae (one pair adcloacal, one just posterior to mid-tail, and one near the tail tip), association with Kradibia spp. pollinating wasps and apparent biogeographical range. A key to the known species and morphospecies of Schistonchus from Australia is presented.
