Two new ostracod genera of the family Trachyleberididae Sylvester-Bradley, 1948, each based on a new species, are described and commented here. The specimens were collected in Tortonian sediments cropping out at El Hadjra Safra in the El Ma El Abiod basin (region of Tébessa, north-eastern Algeria).

Treinta estaciones en el Parque Nacional El Kala (Noreste de Argelia) fueron objeto de un inventario florístico que se centró en el estudio de la ecología de geófitos bulbosos y tuberosos. La flora se caracteriza por una alta proporción de taxones raros y/o endémicos, entre ellos, 6 especies son endemismos algero-tunecinos pertenecientes a la familia Orchidaceae. En este trabajo, se da a conocer la presencia de una nueva especie para la flora argelina, Ophrys fusca subsp. lupercalis. Los análisis multivariantes revelaron, ciertas variables ambientales que determinan la distribución de los geófitos. Los lugares de interés son particularmente sensibles a las amenazas, particularmente las de origen antrópico. Thirty stations at the El Kala National Park (North Eastern Algeria) were the subject of a floristic focused on the study of the ecology of bulbous and tuberous geophytes. The floristic analysis was used to draw up a checklist of 67 species belonging to 36 genera and 14 families, among of which 19 species a high proportion of rare and/or endemic taxa; among them six signed taxa are endemic to algerian-tunisian mainly represented by family of Orchidaceae. In this work, we recorded the presence of a new species for the Algerian flora which is Ophrys fusca subsp. lupercalis. Multivariate analyses revealed certain environmental variables determining the distribution of geophytes. The visited sites show an alarming vulnerability and subject to threats, particularly anthropogenic ones.

A new tribe of the Conocephalinae, Armadillagraeciini Rentz, Su, Ueshima is described to include three known Australiangenera: Armadillagraecia, Kapalgagraecia and Lichenagraecia gen. nov. Lichenagraecia gen. nov. is the eastern repre-sentative of the tribe, the others from the Northern Territory, northern Western Australia and western Queensland. Threenew genera in the tribe Agraeciini are described from the rainforests of north-eastern Queensland, Australia. Ingrischa-graecia gen. nov. is known from a single species, I. iterika sp. nov. Emeraldagraecia gen. nov. is known from two spe-cies, E. munggarifrons and E. windsorana spp. nov. Miniagraecia gen. nov. is described from two species: M. milyali andM. goorijupa spp. nov. In the Listroscelidinae; Requenini, a new species of the previously monotypic genus Xingbaoia,X. irvineorum sp. nov. is described from two localities in peril from repeated prescribed burning. Distribution maps, keys, measurements, song patterns and cytological observations are provided for most species.

A New Species

This research presents three new species of carnivorous sponges from the family Cladorhizidae from the Great Australian Bight, South Australia. This research also shows a clear separation within the species currently known as Cladorhiza into those with an arbuscular or tree-like morphology from the Atlantic, to those of differing morphologies and propose three new genera, i.e. Bathytentacular gen. nov., Abyssosdiskos gen. nov. and Nullarbora gen. nov. and the resurrection of an old genus Axoniderma. nov. The three new species described in this paper are Nullarbora heptaxia sp. nov., Abyssocladia oxyasters sp. nov. and Lycopodina hystrix sp. nov. A new species in the family Guitarridae, Guitarra davidconryi sp. nov., a family closely related to the carnivorous sponges is also described in this paper. These new species are the first recorded carnivorous species from South Australia and increase the number of species recorded from around Australia to 25.

In 1878 Dr. Arnold Forster, in his “Kleine Monographie”, erected many new genera in the family Chalcididæ that have been either overlooked by subsequent entomologists, or, at least, not included in any recent tables of the genera of this family, amongst which is a genus he calls Cratœpus placed by him in the Tetrastichoidœ, and which I am pleased to announce also occurs in America.

The classification of the Trematode family Opisthorchiidæ presents some difficulties to the systematist. These difficulties arise partly from the fact that a number of the existing species appear to lack any real morphological characters by which they can be differentiated, slight variations in measurements, together with a difference in host, having been considered sufficient to justify the making of new species. This view has resulted in the placing of undue importance on somewhat minor differences when they do occur in other species, such differences being considered sufficient for creating new genera.The systematist is further confronted with the difficulty of forming definite opinions on the systematic position of some of the species made by earlier workers. Their descriptions and figures are often inadequate owing to the fact that characters which, in the past, were considered of minor importance are now given much closer attention. Examples of the confusion which has arisen from such a position will be referred to in this paper.

A new species of the family Planorbidae is described from the land thermal spring Khakusy, on the north-eastern shore of Lake Baikal. The description of Gyraulustakhteevi sp. n. includes morphological characters and gene sequences (COI of mtDNA) for the species separation from sister taxon Gyraulusacronicus (A. Férussac, 1807) collected from the small Krestovka River in-flowing into the south-western part of the Lake. The new species differs from G.acronicus in small shell size of adults, having smaller number of prostate folds (maximal up to 26 in G.takhteevi n. sp. vs. 40 in G.acronicus), a short preputium (approximately twice shorter than the phallotheca), and an elongated bursa copulatrix. The population of Gyraulustakhteevi sp. n. consists of two co-existent morphs: one of them has a narrow shell spire and the second is characterized by wide spire similar to the shell of G.acronicus. One of the two revealed haplotypes of the new species includes both morphs, while the second consists of snails with wide spired shells.

AbstractLarval characterizations for the genera of North American Brachycentridae are revised and two new genera created, bringing to five the total number now recognized on this continent. Previous concepts of larval morphology inMicrasemaare emended. Discovery of the larval stage ofBrachycentrus(Amiocentrus)aspilusRoss necessitates elevation of this subgenus to generic status. Association of larvae with the two North American species placed inOligoplectrumnecessitates removal of one,O.dimicki(Milne), toMicrasema. Discovery of all stages of a new species on Mount Hood, Oregon, necessitates creation of a new genus. A provisional larval key to the genera of the North American Brachycentridae is proposed and the phylogenetic relationships of the genera are discussed. Validity of the Asian genusOligoplectrodesis questioned.

A new species of vesicomyid bivalve (Isorropodon nyeggaensis sp. nov.) is described based on shell morphology, from the Nyegga cold methane seep area on the Norwegian continental margin. This is the first description of vesicomyids from the Norwegian Sea and the northernmost record of recent representatives of the family Vesicomyidae. A dispersion of the genus into the Norwegian Sea basin from the north-eastern Atlantic is suggested. A brief description of other macrofauna from methane seep sites at Nyegga is also given.
