STEBBINS 1,* and DOUGLAS J. EERNISSE 2 1 City of San Diego Marine Biology Laboratory, Metropolitan Wastewater Department, San Diego, CA, USA 2 Department of Biological Science, California State University, Fullerton, CA, USA Abstract: About 36 species of chitons possibly occur at depths greater than 30 m along the continental shelf and slope of the Southern California Bight (SCB), although little is known about their distribution or ecology. Nineteen species are reported here based on chitons collected as part of long-term, local benthic monitoring programs or less frequent region-wide surveys of the entire SCB, and these show little overlap with species that occur at depths typically encountered by scuba divers. Most chitons were collected between 30-305 m depths, although records are included for a few from slightly shallower waters. Of the two extant chiton lineages, Lepidopleurida is represented by Leptochitonidae (2 genera, 3 species), while Chitonida is represented by Ischnochitonidae (2 genera, 6-9 species) and Mopaliidae (4 genera, 7 species). -

Molecular Phylogeny of Echiuran Worms (Phylum: Annelida) Reveals Evolutionary Pattern of Feeding Mode and Sexual Dimorphism
Molecular Phylogeny of Echiuran Worms (Phylum: Annelida) Reveals Evolutionary Pattern of Feeding Mode and Sexual Dimorphism Ryutaro Goto1,2*, Tomoko Okamoto2, Hiroshi Ishikawa3, Yoichi Hamamura4, Makoto Kato2 1 Department of Marine Ecosystem Dynamics, Atmosphere and Ocean Research Institute, The University of Tokyo, Kashiwa, Chiba, Japan, 2 Graduate School of Human and Environmental Studies, Kyoto University, Kyoto, Japan, 3 Uwajima, Ehime, Japan, 4 Kure, Hiroshima, Japan Abstract The Echiura, or spoon worms, are a group of marine worms, most of which live in burrows in soft sediments. This annelid- like animal group was once considered as a separate phylum because of the absence of segmentation, although recent molecular analyses have placed it within the annelids. In this study, we elucidate the interfamily relationships of echiuran worms and their evolutionary pattern of feeding mode and sexual dimorphism, by performing molecular phylogenetic analyses using four genes (18S, 28S, H3, and COI) of representatives of all extant echiuran families. Our results suggest that Echiura is monophyletic and comprises two unexpected groups: [Echiuridae+Urechidae+Thalassematidae] and [Bone- lliidae+Ikedidae]. This grouping agrees with the presence/absence of marked sexual dimorphism involving dwarf males and the paired/non-paired configuration of the gonoducts (genital sacs). Furthermore, the data supports the sister group relationship of Echiuridae and Urechidae. These two families share the character of having anal chaetae rings around the posterior trunk as a synapomorphy. The analyses also suggest that deposit feeding is a basal feeding mode in echiurans and that filter feeding originated once in the common ancestor of Urechidae. Overall, our results contradict the currently accepted order-level classification, especially in that Echiuroinea is polyphyletic, and provide novel insights into the evolution of echiuran worms. -

Towards a Regional Information Base for Lake Tanganyika Research
RESEARCH FOR THE MANAGEMENT OF THE FISHERIES ON LAKE GCP/RAF/271/FIN-TD/Ol(En) TANGANYIKA GCP/RAF/271/FIN-TD/01 (En) January 1992 TOWARDS A REGIONAL INFORMATION BASE FOR LAKE TANGANYIKA RESEARCH by J. Eric Reynolds FINNISH INTERNATIONAL DEVELOPMENT AGENCY FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS Bujumbura, January 1992 The conclusions and recommendations given in this and other reports in the Research for the Management of the Fisheries on Lake Tanganyika Project series are those considered appropriate at the time of preparation. They may be modified in the light of further knowledge gained at subsequent stages of the Project. The designations employed and the presentation of material in this publication do not imply the expression of any opinion on the part of FAO or FINNIDA concerning the legal status of any country, territory, city or area, or concerning the determination of its frontiers or boundaries. PREFACE The Research for the Management of the Fisheries on Lake Tanganyika project (Tanganyika Research) became fully operational in January 1992. It is executed by the Food and Agriculture organization of the United Nations (FAO) and funded by the Finnish International Development Agency (FINNIDA). This project aims at the determination of the biological basis for fish production on Lake Tanganyika, in order to permit the formulation of a coherent lake-wide fisheries management policy for the four riparian States (Burundi, Tanzania, Zaïre and Zambia). Particular attention will be also given to the reinforcement of the skills and physical facilities of the fisheries research units in all four beneficiary countries as well as to the buildup of effective coordination mechanisms to ensure full collaboration between the Governments concerned. -

Out of Lake Tanganyika: Endemic Lake Fishes Inhabit Rapids of the Lukuga River
355 Ichthyol. Explor. Freshwaters, Vol. 22, No. 4, pp. 355-376, 5 figs., 3 tabs., December 2011 © 2011 by Verlag Dr. Friedrich Pfeil, München, Germany – ISSN 0936-9902 Out of Lake Tanganyika: endemic lake fishes inhabit rapids of the Lukuga River Sven O. Kullander* and Tyson R. Roberts** The Lukuga River is a large permanent river intermittently serving as the only effluent of Lake Tanganyika. For at least the first one hundred km its water is almost pure lake water. Seventy-seven species of fish were collected from six localities along the Lukuga River. Species of cichlids, cyprinids, and clupeids otherwise known only from Lake Tanganyika were identified from rapids in the Lukuga River at Niemba, 100 km from the lake, whereas downstream localities represent a Congo River fish fauna. Cichlid species from Niemba include special- ized algal browsers that also occur in the lake (Simochromis babaulti, S. diagramma) and one invertebrate picker representing a new species of a genus (Tanganicodus) otherwise only known from the lake. Other fish species from Niemba include an abundant species of clupeid, Stolothrissa tanganicae, otherwise only known from Lake Tangan- yika that has a pelagic mode of life in the lake. These species demonstrate that their adaptations are not neces- sarily dependent upon the lake habitat. Other endemic taxa occurring at Niemba are known to frequent vegetat- ed shore habitats or river mouths similar to the conditions at the entrance of the Lukuga, viz. Chelaethiops minutus (Cyprinidae), Lates mariae (Latidae), Mastacembelus cunningtoni (Mastacembelidae), Astatotilapia burtoni, Ctenochromis horei, Telmatochromis dhonti, and Tylochromis polylepis (Cichlidae). The Lukuga frequently did not serve as an ef- fluent due to weed masses and sand bars building up at the exit, and low water levels of Lake Tanganyika. -

The Dustywings in Cretaceous Burmese Amber (Insecta: Neuroptera: Coniopterygidae)
Journal of Systematic Palaeontology 2 (2): 133–136 Issued 23 July 2004 DOI: 10.1017/S1477201904001191 Printed in the United Kingdom C The Natural History Museum The Dustywings in Cretaceous Burmese amber (Insecta: Neuroptera: Coniopterygidae) Michael S. Engel Division of Entomology, Natural History Museum and Department of Ecology and Evolutionary Biology, Snow Hall, 1460 Jayhawk Boulevard, University of Kansas, Lawrence, KS 66045-7523, USA SYNOPSIS The dustywing fauna (Neuroptera: Coniopterygidae) of Upper Albian Burmese amber is revised. Two species are recognised, one belonging to the subfamily Aleuropteryginae and one to the Coniopteryginae. The aleuropterygine species is placed in the genus Glaesoconis (Glaesoconis baliopteryx sp. nov.), a previously known fontenelleine genus from New Jersey and Siberian ambers. The apparent coniopterygine differs in several features of wing venation and is therefore placed in its own tribe: Phthanoconini nov. (Phthanoconis burmitica gen. et sp. nov.). A revised key to Cretaceous dustywing genera is provided. KEY WORDS Aleuropteryginae, Coniopteryginae, Myanmar, Neuropterida, Planipennia, taxonomy Introduction arthropods such as mites living on conifers and deciduous trees or shrubs (Meinander 1972). The earliest fossil of the The Neuropterida (Neuroptera, Megaloptera and Raphidiop- family is Juraconiopteryx from the Upper Jurassic Karatau tera) are one of the most distinctive and ancient of endop- deposits in southern Kazakhstan (Meinander 1975) and, al- terygote lineages. Stem-group neuropterids occurred during though placed in Aleuropteryginae, little is preserved so that the Lower Permian with putative basal members of the or- assignment must be considered tentative. The earliest defin- ders Neuroptera and Megaloptera appearing shortly there- itive members of the family are those in Lower Cretaceous after and the earliest records of Raphidioptera coming from amber from Lebanon (Whalley 1980; Azar et al.
