P. Payne MSc Thesis, Department of Biodiversity and Conservation Biology, University of the Western Cape. Seamounts are poorly understood ubiquitous undersea features, with less than 4% sampled for scientific purposes globally. Consequently, the fauna associated with seamounts in the Indian Ocean remains largely unknown, with less than 300 species recorded. One such feature within this region is Walters Shoal, a shallow seamount located on the South Madagascar Ridge, which is situated approximately 400 nautical miles south of Madagascar and 600 nautical miles east of South Africa. Even though it penetrates the euphotic zone (summit is 15 m below the sea surface) and is protected by the Southern Indian Ocean Deep- Sea Fishers Association, there is a paucity of biodiversity and oceanographic data. -

Prey preferences and feeding-related behaviour of a Central European species of Scydmaeninae, Euconnus pubicollis, were studied under laboratory conditions. Results of prey choice experiments involving 50 species of mites belonging to 24 families of Oribatida and one family of Uropodina demonstrated that beetles feed mostly on ptyctimous Phthiracaridae (over 90% of prey) and only occasionally on Achipteriidae, Chamobatidae, Steganacaridae, Oribatellidae, Ceratozetidae, Euphthiracaridae and Galumni- dae. The average number of mites consumed per beetle per day was 0.27 ± 0.07, and the entire feeding process took 2.15–33.7 h and showed a clear linear relationship with prey body length. Observations revealed a previously unknown mechanism for capturing prey in Scydmaeninae in which a droplet of liquid that exudes from the mouth onto the dorsal surface of the predator’s mouthparts adheres to the mite’s cuticle. Morphological adaptations associated with this strategy include the flattened distal parts of the maxillae, whereas the mandibles play a minor role in capturing prey. -

Larvae of the Moorish Idol, Zanclus Cornutus, Including a Comparison with Other Larval Acanthuroids
BULLETIN OF MARINE SCIENCE. 40(3): 494-511. 1987 CORAL REEF PAPER LARVAE OF THE MOORISH IDOL, ZANCLUS CORNUTUS, INCLUDING A COMPARISON WITH OTHER LARVAL ACANTHUROIDS G. David Johnson and Betsy B. Washington ABSTRACT The larvae of Zane/us carnutus are described and illustrated based on one postflexion and several preflexion specimens. In addition to general morphology and pigmentation, bony ornamentation ofthe head bones and other osteological features are described in detail. Head bones and the associated ornamentation are illustrated for larval Zane/us, Siganus. Luvarus and Nasa. These and other aspects of the morphology of larval acanthuroids are compared and discussed within the context of a phylogenetic hypothesis proposed in other current work. Larval characters corroborate the monophyly of the Acanthuroidei and the phyletic sequence, Siganidae, Luvaridae, Zanc1idae, Acanthuridae. The Acanthuridae is represented by three distinct larval forms. The moorish idol, Zane/us cornutus (Linnaeus), Family Zanclidae, occurs in tropical waters of the Indo-Pacific and eastern Pacific. Like the closely related Acanthuridae, adult Zane/us are reef-associated fishes, but the young are spe- cialized for a relatively prolonged pelagic existence. The specialized pelagic pre- juvenile is termed the "acronurus" stage, and, at least in acanthurids, may reach a length of 60 mm or more before settling (Leis and Rennis, 1983). Strasburg (1962) briefly described 13.4 and 16.0-mm SL specimens ofthe monotypic Zan- e/us and illustrated the larger specimens. Eggs, preflexion larvae and small post- flexion larvae of Zane/us have not been described (Leis and Richards, 1984). The primary purposes of this paper are to describe a 9.S-mm SL postflexion larva of Zane/us and to compare its morphology to that of postflexion larvae of other acanthuroids in a phylogenetic context. -

(Orthoptera) and Their Phylogenetic Implications Within Tetrigoidea
Mitochondrial genomes of eight Scelimeninae species (Orthoptera) and their phylogenetic implications within Tetrigoidea Ran Li1, Xiaoli Ying1, Weian Deng2, Wantao Rong2 and Xiaodong Li2 1 College of Life Sciences, Nanjing Normal University, Nanjing, China 2 School of Chemistry and Bioengineering, Hechi University, Yizhou, China ABSTRACT Scelimeninae is a key member of the pygmy grasshopper community, and an important ecological indicator. No mitochondrial genomes of Scelimeninae have been reported to date, and the monophyly of Scelimeninae and its phylogenetic relationship within Tetrigidae is still unclear. We sequenced and analyzed eight nearly complete mitochondrial genomes representing eight genera of Scelimeninae. These mitogenomes ranged in size from 13,112 to 16,380 bp and the order of tRNA genes between COII and ATP8 was reversed compared with the ancestral order of insects. The protein-coding genes (PCGs) of tetrigid species mainly with the typical ATN codons and most terminated with complete (TAA or TAG) stop codons. Analyses of pairwise genetic distances showed that ATP8 was the least conserved gene within Tetrigidae, while COI was the most conserved. The longest intergenic spacer (IGS) region in the mitogenomes was always found between tRNASer(UCN) and ND1. Additionally, tandem repeat units were identified in the longest IGS of three mitogenomes. Maximum likelihood (ML) and Bayesian Inference (BI) analyses based on the two datasets supported the monophyly of Tetriginae. Scelimeninae was classified as a non-monophyletic subfamily. -

The 242 new species are distributed unevenly among 50 families, with 62% of the total from the top 10 families. Geographically, these species are distributed unevenly among 39 countries. Most new species (72%) are from the top 10 countries, whereas 61% of the countries have only 1–3 new species each. Four of the top 10 countries are from Asia (Vietnam, China, India and The Philippines).

These possibilities of having the editors working alongside provide an efficient work in a shorter time. We definitely need to have these workshops periodically. The objectives of this workshop were: (i) to evaluate the work that has been done over the past three years and the maintenance of the database, (ii) to welcome the editors of terrestrial and fresh water nematodes, set clear goals, assign tasks and initiate the practical work related to new initiatives and (iii) to outline practices for outreach and scientific output for Nemys (e.g. scientific papers, presentations of the progress, plans and results at an upcoming conference). On the first day it was asked to have a rapporteur for each session in order to have it registered. The original minutes are on a separate document and were used to generate this report.

Nematode communities consisted of 23 genera belonging to 19 families, 8 orders for the dry and 24 genera, 17 families, 8 orders for the pre-rainy season. Several genera dominated in Tri An Reservoir such as Daptonema, Rhabdolaimus, Udonchus, and Neotobrilus indicated for organic enrichment conditions. The percentage of cp3&4 and MI (Maturity Index) value in the dry season was higher than that in the pre-rainy season expressed the ecological quality status of sediment in the dry season were better than those in the pre-rainy season. Furthermore, the result revealed that MI and c-p% composition can be used to evaluate the ecological quality status of sediment efficiently.
