The Limonium binervosum aggregate (Plumbaginaceae) in the British Isles

A taxometric analysis of 153 colonies of the agamospermous Limonium binervosum aggregate in the British Isles has revealed an ordered hierarchy of variation. A taxonomic treatment of the group describes five new species, redefines four others and describes other infraspecific variants as subspecies or varieties. Each species is morphologically distinct and has a defined geographic range. There are four widespread and morphologically variable species and five geographically restricted species (four monotypic). Limonium recurvum , previously described as a microspecies endemic to a small area of the Dorset Coast, has been widened to include all triploid (2 n = 27) L. binervosum agg. variants found also in W and N Ireland, SW Scotland and Cumbria. All other taxa are tetraploid, usually with 2 n = 35.     

Molecular phylogeny of Plumbaginaceae with emphasis on Acantholimon Boiss. based on nuclear and plastid DNA sequences in Iran

The present study represents phylogenetic analyses of Plumbaginaceae with emphasis on Acantholimon from Iran using nrDNA ITS and plastid trnY-T sequences. The analyses support the monophyly and the close relationship of Limonium, Armeria and Psylliostachys. This is the first report of the close relationship between Acantholimon and Cephalorhizum. The data for the position of Cephalorhizum is unclear. The Shimodaira–Hasegawa test of nrDNA ITS and the combined datasets indicated that Acantholimon and Cephalorhizum are distinct genera. The molecular data revealed that the traditionally recognized multi-specific Acantholimon sections (Acantholimon, Acmostegia, Glumaria, Microstegia, Staticopsis and Tragacanthina) are not monophyletic. Their members are intermixed with each other and scattered across the Acantholimon clade, but the smaller sections including Platystegia and Pterostegia, each comprising two species, are monophyletic.     

Nacobbodera chitwoodi,n. gen., n. sp., (Nacobbidae:Nematoda) on Douglas Fir in Oregon

Nacobbodera chitwoodi, n. gen., n. sp., representing Nacobboderinae n. subfam, in the Nacobbidae, is described and illustrated from roots of Douglas fir, Pseudotsuga menziesii near Florence Oregon. This new species, having characters common to Nacobbidae, Heteroderidae, and Meloidogynidae, appears to represent a connecting link between these three families of the Heteroderoidea. Especially, a distinct tail on swollen adult females, vermiform shape of juvenile females, and the shape and sclerotization of the head of the various stages, indicate a Nacobbidae relationship. Certain other characteristics present in this new species are of the Heteroderidae and Meloidogynidae type as follows: Gross shape of adult female in posterior half of body, two ovaries, anterior position of excretory pore as in Meloidogyne females, absence of a bursa, and development of male within a sausage-shaped cuticle as in root-knot and cyst nematodes.     

Acantholimon doganii sp. nov. (Plumbaginaceae) with persistent circinnate leaf bases, from Turkey

Diagnostic morphological characteristics in closely related species are discussed and the conservation status of the new species is analysed. A revised key to the Turkish Acantholimon species with persistent circinnate leaf basis is also provided.     

Reassessment of the isopod crustacean Aega deshaysiana (Milne Edwards, 1840) (Cymothoida: Aegidae): a world-wide complex of 21 species

Aega deshaysiana (Milne Edwards, 1840) and A. antillensis Schioedte & Meinert, 1879, have long been confounded, with all records eventually becoming regarded as belonging to one globally distributed species, namely A. deshaysiana. These two species are redescribed and differentiated, with A. schioedteana Bovallius, 1885 remaining in synonymy with A. deshaysiana. Aega deshaysiana occurs only in the eastern North Atlantic and Mediterranean, while A. antillensis is known only from the Caribbean and Gulf of Mexico. A further two named species are redescribed: A. excisa Richardson, 1910, previously placed in synonymy with A. deshaysiana, and A. magnifica (Dana, 1852). A neotype is designated for A. magnifica. This ‘complex’ or group of Aega species is distinguished from the others by their large eyes, which are usually medially united and occupy most of the head, their large adult size (20–60 mm), a posteriorly acute and defined pleotelson apex, and the uropod rami not extending posteriorly beyond the pleotelson, with exopod held at an oblique angle to the endopod and deeply notched endopod lateral margin. The group is not necessarily monophyletic, as there is a gradation in the depth of the uropod notch from deep to scarcely evident, and in eye size from entirely occupying the head to just separate (though the eyes are always large). Twelve new species in the group are described. All species are considered to be micropredators of fishes and elasmobranches, although prey records are few and unreliable owing to the readiness of these isopods to detach. Species of the group have been recorded from depths varying between 10 m and 600 m and occasionally deeper. Several have extensive distributions ranging from the Southern Ocean to tropical waters. The group is represented in all oceans. © 2004 The Linnean Society of London, Zoological Journal of the Linnean Society, 2004, 142 , 135–232.     

Revision of the Acanthoclinidae (Pisces: Perciformes), with descriptions of a new genus and five new species

Abstract

The family Acanthoclinidae includes 10 species: Acanthoclinus fuscus Jenyns, 1842; Taumakoides littoreus ((Forster) Bloch & Schneider, 1801); T. rua n. sp.; T. marilynae n. sp.; T. matti n. sp.; Belonepterygion fasciolatum (Ogilby, 1889); Beliops xanthokrossos n. gen. et sp.; Acanthoplesiops indicus (Day, 1888); A. hiatti Schultz, 1953; and A. psilogaster n. sp. Acanthoclinus quadridactylus (Bloch & Schneider, 1801) and A. trilineatus Griffin, 1933, are reduced to synonymy under Taumakoides littoreus ((Forster) Bloch & Schneider, 1801).

Osteological and morpological character states, between and within genera, suggest that Acanthoclinus and Taumakoides are close to the stock from which the family is derived. There is also compelling evidence that T. matti is the least specialised species of Taumakoides. Progressive specialisation is evident in the remaining genera, with Acanthoplesiops being the most highly specialised.

The family occurs primarily in shallow waters of the Indian and western Pacific oceans; most of the species are found about New Zealand. The centre of origin of the Acanthoclinidae was probably on the Indian-Australian Plate (which includes the New Zealand continental shelf). Acanthoplesiops hiatti and A. indicus are considered to be endemics of the Pacific and African plates, respectively.

A key to species is included.

Identification of the areas of endemism (AOEs) of the genus Acantholimon (Plumbaginaceae) in Iran

Abstract

This study was conducted to identify areas of endemism for Acantholimon species using parsimony analysis of endemicity (PAE) and to detect endemic species richness of the genus in the region. The results obtained from the two methods used in this study were used in determining the priorities for the conservation of Acantholimon species in Iran. The distribution database of 62 endemic species belonging to this genus was formed by 1250 georeferenced observations in Iran. The study area was divided into 1?×1? grids of operative geographical units (OGUs) and the species?×?area matrix including presence/absence data was created. The endemic species richness was calculated using circular neighborhood with a radius of 50?km in 10?×?10?km² raster cells using DIVA-GIS software. The results of PAE analysis have shown four areas of endemism (AOEs) in Iran. AOE1: including Alborz and Zagros mountains, the mountains of central Iran. AOE2 and AOE3 are located in Khorassan subregion and AOE4 contains parts of western Iran. The map of endemic species richness indicated that the highest number of endemic species occurs in central Alborz region as well as Kerman, Chahar-Mahal and Bakhtiari, and Isfahan provinces.
