New species and new records of recently described species of the coral genus Acropora (Scleractinia: Astrocoeniina: Acroporidae) from Indonesia

Six new species of the coral genus Acropora arc described from Indonesia. These include a species which is remarkable for tubercular cocnostcal structures similar to those of the confamilial genus Montipora. The new species include three regional endemics (A. togianensis and A. batunai from central east Sulawesi and A. derawanensis from east Kalimantan), one species with broad distribution across the southern island chains (A. sukarnoi) and two species which occur throughout most of the Indonesian archipelago (A. Indonesia and A. hoeksemai). A further two species described from Western Australia and Papua New Guinea in 1994 (A. turaki and A. jacquelineae respectively) are recorded from Indonesia for the first time, as common members of an unusual assemblage type in the Togian Islands. The range of another species described from Lombok in 1994 (A. suharsonoi) is extended into Bali. With A. desalwii, A. lokani and A. indiana , this brings to 12 the number of Acropora species newly recorded as being endemic to the Indonesian archipelago or to Indonesia and one adjoining region (either the Indian Ocean or the western Pacific).     

A new species of Bricelochlorops Paganelli and the first record of Urubambina rufa (Duda) (Diptera: Chloropidae) from Brazil

The subfamily Chloropinae comprises about 442 described species, with only one species recorded from the Brazilian Amazon. The genus Bricelochlorops Paganelli was represented by a unique species from Rio de Janeiro, Brazil. The species Urubambina rufa (Duda) is the only species of the genus Urubambina Paganelli and has been recorded only from Peru. A new species of Bricelochlorops, B. celutae sp. nov., is described here and Urubambina rufa is recorded for the first time in Brazil. Both species were collected in the state of Acre. A key to species of Bricelochlorops is provided.

Trophic levels in community food webs

Summary Four concepts are considered for the trophic level of a species in a community food web. The long-way-up-level (or LU-level) of species A is the length of the longest simple food chain from a basal species (one with no prey in the web) to A. (A simple chain is a chain that does not pass through any given species more than once.) The short-way-up-level (SU-level) of species A is the length of the shortest chain from a basal species to A. The long-way-down-level (LD-level) of species A is the length of the longest simple chain from species A to a top species (one with no consumers in the web). The short-way-down-level (SD-level) of species A is the length of the shortest chain from species A to a top species. The stratigraphy of a web is the analogue for species of the pyramid of numbers for individuals: it is the frequency distribution of species according to level. The LU-, SU-, LD-, and SD-stratigraphies of the seven webs in the Briand-Cohen collection with 30 or more trophic species reveal no species with LU-level or LD-level more than 6, no species with SU-level more than 3, and no species with SD-level more than 2. In all seven webs, SD-levels are stochastically less than SU-levels: species tend to be closer to a top predator than to a basal species. Two stochastic models of food web structure (the cascade model and the homogeneous superlinear model) correctly predict that 95% or more of species should have LU-level and LD-level in the range 0–6. The models also correctly predict some details of the distribution of species in the SU- and SD-stratigraphies, particularly the fraction of species in level 1. The models do not, in general, correctly predict the distribution of species within the range 0–6 of LU-levels and LD-levels.

REVISION OF THE GENUS APHYTIS (HYMENOPTERA: APHELINIDAE) WITH DESCRIPTIONS OF TWO NEW SPECIES FROM EGYPT

Abstract  The Egyptian species of the aphelinid genus Aphytis Howard are reviewed. Aphytis azai Abd-Rabou and Aphytis matruhi Abd-Rabou are described as new species from Egypt. Each species is briefly diagnosed and known information on hosts and distributed is given. A. azai sp. nov. is similar to A. melinus but different in the measurement of antennal segments. A. matruhi sp. nov. differs from A. lepidosaphes by the relative length of propodeum, metanotum and scutellum. A key to the Egyptian species of Aphytis is provided.     

A new species of Anisakis Dujardin, 1845 (Nematoda, Anisakidae) from beaked whales (Ziphiidae): allozyme and morphological evidence

Larvae and adults of Anisakis, recovered from the beaked whales Mesoplodon layardii and Ziphius cavirostris from the Mediterranean Sea and South African waters, were analysed morphologically and by molecular markers (allozymes). A new Anisakis species was identified, showing fixed allele differences at a number of loci from the other Anisakis spp. tested (A. simplex complex, A. physeteris). The lack of hybrid or recombinant genotypes in mixed infections with A. pegreffii, A. simplex C and A. physeteris, as well as the high values of genetic distance (average D_Nei = 1.65 from the members of the A. simplex complex, and D_Nei = 3.09 from A. physeteris) showed that the new species is reproductively isolated. This new Anisakis species is morphologically different from the other Anisakis retained by Davey (1971) as either good species or species inquirendae. The name Anisakis ziphidarum n. sp. is proposed for the new species.
