| A morphologically distinct cavernicolous salamander Proteus anguinus from southeastern Slovenia (Bela Krajina) is described as P. a. parkelj ssp. n. It differs from P. a. anguinus in a dark pigmentation, fully developed eyes, a skull with broader and shorter bones and fewer teeth, a voluminous jaw musculature that gives the head a bulky appearance, a proportionally longer trunk with a higher number of vertebrae, shorter extremities, and a shorter tail. Most of these traits are considered to be plesiomorphic character states. An allozyme analysis over 40 loci has shown the new dark pigmented taxon to be genetically similar to a white and troglomorphic neighbouring population from Stična (DNei = 0.23). Both populations in turn are genetically dissimilar to a... |

| Quota allocation mechanisms have distributional effects that are highly relevant to the economic organization of fisheries. In France, where fishing allocations are non-transferable, quotas are shared among Producer Organizations (POs) based on the historical landings of their members. Each PO is then responsible for implementing their own internal rules that provide individual or collective allocations to their members. This study investigates the distributional effects of the various quota management systems adopted by POs on quotas and production for the Bay of Biscay sole fishery. A comparison between initial allocations by vessel based on historical landings and actual observed landings is presented. Inequality metrics are used to quantify... |

| ABSTRACT We report new records of Gnamptogenys caelata Kempf (1967) and Gnamptogenys minuta (Emery, 1896) from Brazil. We also describe Gnamptogenys piei n. sp. from Southeast Brazil. This distinctive new species is known only from a single worker found in leaf litter from montane forests of the Mantiqueira mountains in Itatiaia National Park, Rio de Janeiro State, Brazil. The specimen was collected at 1991 m above sea level, an infrequent altitude for minuta-group ants, usually more common at lower altitudes. The new species is imaged, compared with other minuta-group species, and an updated identification key for all known species of the minuta-group is included. |

| Here we describe a new species of Echimyidae Amazonian rodent, Echimys vieirai sp. nov., based on two individuals from the south bank of Amazon river between the lower Madeira river to the right bank of the Tapajós, respectively in the Brazilian states of Amazonas and Pará, Brazil. The main diagnostic characteristic of this new species is the presence of a dorsal median dark maroon stripe on the head, running from the rostrum to the nape. Skull morphology is quite similar to that of Echimys chrysurus (Zimmermann, 1780), but our new species differ from other species in the genus by the development of the alisphenoid canal and dp4 morphology. Additionally, we offer a refinement of the diagnosis of the genera Echimys and Makalata. |

| ABSTRACT A new species of the characid genus Knodus is described from the rio Aripuanã (rio Madeira basin). It can be distinguished from its congeners by its very low body depth, the presence of tri- to pentacuspid teeth on the outer premaxillary series, with the median cuspid larger than the lateral ones, the teeth of the inner premaxillary series pentacuspid, distinctly larger than those of the outer series, the maxillary teeth tri- to pentacuspid, with the median cusp slightly larger than the lateral ones, the four anteriormost dentary teeth pentacuspid, the smaller posterior teeth tri- to pentacuspid, a complete lateral line with 36-38 scales, 3 longitudinal scale series from pelvic fin origin to lateral line, and 11-12 circumpeduncular scales. The new... |

| A new species of Roeboides is described from the Pacific slope of Costa Rica and Panama. Roeboides bussingi differs from all other Central American Roeboides and all members of the R. guatemalensis species group by the following combination of characters: presence of 18-22 scales above the lateral line (vs. 12-16 in R. dientito); 15-22 scales below the lateral line (vs. 10-14 in R. dientito, and 20-24 in R. loftini); an inconspicuous, sometimes absent, crescent-shaped humeral spot (vs. a large round, conspicuous humeral spot in R. carti, R. dayi, R. dientonito, R. ilseae, R. loftini,and R. occidentalis); a small wedge-shaped spot that does not reach the lateral line (vs. a large spot crossing the lateral line in R. guatemalensis); a teardrop shaped caudal... |

| Saccharosydne is the most diverse genus of the tribe Saccharosydnini. Male, female and nymphal Saccharosydne have been captured in recent collections from garlic (Allium sativum), rye (Secale cereale) and pampas grass (Cortaderia spp.) in Argentina. In this contribution, we describe and illustrate a new species S. subandina sp. nov., adding information on the geographical distribution and host plants. Saccharosydne subandina can be distinguished from its congeners by the following combination of features: uniformly light green-yellowish color with a distinctive rounded black macula on both genae; vertex 1.5x longer than wide, and projecting beyond eyes almost one half of its length; parameres divergent with internal and external angles acute; and... |

| Bunodes biscayensis Fischer, 1874, a species of Actiniaria described from Moulleau, Arcachon, south-western coast of France, and never recorded since, was rediscovered in July 1985 and found again in 1986 and 1987 in several localities along the French "Côte Basque" between the mouth of the river Adour and St. Jean-de-Luz. The species is here redescribed and referred to Bunodosoma Verrill, 1899, a genus of tropical and subtropical Atlantic and West-American intertidal and shallow water forms, hitherto not recorded from the Mediterranean and/or the Atlantic coast of Europe. Speculations are advanced as to the possible further distribution of B. biscayensis. A discussion is added concerning the morphological terms verruca and vesicle. The study is completed... |

| Material currently classified under the name Aricoris constantius (Fabricius, 1793) is examined and found to consist of three distinct species inhabiting southeastern and central Brazil, from the Brazilian state of Bahia to Paraguay. They are A. constantius, A. tutana (Godart, [1824]), reinstated status and A. monotona (Stichel, 1910), reinstated status, the latter two removed from synonymy. Besides significant morphological differences in wing pattern and genitalia, their status as separate species is supported by their overlapping ranges where each phenotype is sympatric with at least one other, with no evidence of hybridization. Notes are provided on the habitat in open formations, range and distribution in south eastern Brasil, and biology, including... |

| This paper presents a summary of the current knowledge on the systematics of the Greek taxa of Chorthippus, morphologically characterised by angled lateral pronotal keels (usually grouped as Glyptobothrus). Prior to this paper, based on traditional morphology, ten taxa of Chorthippus with angled lateral pronotal keels were recognized from Greece. Based on morphology as well as (and more importantly so) bioacoustics thirteen Greek taxa are now recognised. With addition of a few additional related taxa that occur only outside Greece, all are treated in this paper: Chorthippus apricarius apricarius (Linnaeus, 1758), C. vagans vagans (Eversmann, 1848) (not in Greece), C. v. cypriotus (Uvarov, 1936) stat. nov. [Cyprus], C. v. africanus Nadig, 1981 [N. Africa],... |
