Earthworms (Clitellata, Acanthodrilidae) of the mountains of Eastern Jamaica

Fourteen species new to science are described from material collected at several sites in the Blue Mountains and the John Crow Mountains of eastern Jamaica, doubling the known endemic Jamaican earthworm fauna. New data on Dichogaster montecyanensis (Sims) are provided. All species are placed in the genus Dichogaster Beddard, which is here treated sensu lato, i.e. including Eutrigaster Cognetti. Eight of the new species have lost the posterior pair of prostates and the seminal grooves of the male field. These are D. bromeliocola, D. crossleyi, D. davidi, D. garciai, D. harperi, D. haruvi, D. hendrixi, and D. johnsoni. D. sydneyi n. sp. has independently lost the posterior prostates but not the seminal grooves. The new species D. altissima and D. manleyi have the conventional dichogastrine prostatic battery and male field characteristics. Three species described here, D. farri, D. garrawayi, and D. marleyi, all have a third pair of prostates in the 20th segment, no seminal grooves, dorsal paired intestinal caeca in segment lxv, and lack penial setae.     

Studies in SE Asiatic Rondeletieae II: Aleisanthiopsis (Rubiaceae), a new genus from Borneo

The gem Aleisanthiopsis is described to accommodate the species Greenea distantiflora and a new species Aleisanthiopsis multiflora described here. The character states of Aleisanthiopsis are presented. Illustrations are provided for both species. An approximate chromosome count is given for A. distantiflora . It is suggested, that Aleisanthiopsis may be the sister genus to Aleisanthia , a genus currently placed in the Rondeletieae subfamily Cinconoideae. It is shown that the genus Greeniopsis is very similar to Aleisanthia and Aleisanthiopsis except for the seed characters.     

Studies on the Lumbriculidae (Oligochaeta) in Britain

Seven species of Lumbriculidae, a family of fresh water Oligochaeta, found in Britain are described and a key is erected for their identification. Two species of Trichodrilus , separated by Beddard are redescribed, resulting in a new synonymy. Trichodrilus Hrabêi sp. n. from Denbighshire is denned. Dorydrilus michaeheni is recorded for the first time from Great Britain.     

Nine new species of Dichogaster (Oligochaeta, Megascolecidae) from Guadeloupe (French West Indies)

Nine species belonging to two distinct groups within the genus Dichogaster Beddard, 1888 are described from material collected on the volcanic section of the island of Guadeloupe. The species Dichogaster arborea, D. caesitifusca, D. callaina, D. girija and D. basseterrensis all inhabit the leaf tanks of bromeliads and share the following anatomical characteristics: spermathecal pores on the trailing edges of segments, spermathecal axis differentiated into ampulla, internally fluted central chamber and duct, penial setae long and slender, testes and funnels free, prostomium undivided or divided by two grooves, simple single typhlosole and a pair of dorsal caeca on the mid-intestine. Dichogaster athena also inhabits bromeliads, but lacks the above characteristics and male reproductive organs, and is more similar to the remaining species. The three remaining species, D. guadeloupensis, D. matoubensis and D. musciphila , with lateral typhlosoles, no intestinal caeca, simpler spermathecal structure, prostomiums divided by a single groove and short penial setae, all inhabit soils of montane forests. The division of Dichogaster based on muscularity of the proventriculus wall is shown to be unsupportable, since thickness of the wall is size-related.     

Lutzomyia derelicta (Diptera: Psychodidae) a singular new phlebotomine sand fly from an Inselberg in Northeastern Amazonia.

Lutzomyia derelicta n. sp. is described from specimens collected in an isolated xeric habitat in the rainforest in the north of the State of Pará, Brazil. The new species lacks the posterior bulge in the dorsal wall of the cibarium characteristic of the New World genus Lutzomyia, and the armature of the male genitalia is of the pattern found elsewhere only in the Old World species of Sergentomyia. L. derelicta is phenetically intermediate between the known species of Lutzomyia and Sergentomyia, and cannot readily be placed in any existing subgenus or species group of either genus.     

The Chromodorididae (Opisthobranchia: Mollusca) of the Indo-West Pacific: the genus Glossodoris Ehrenbergh (= Casella, H. & A. Adams)

The genus Glossodoris Ehrenberg is reviewed and 28 species are placed in the genus. Seventeen species are fully described and of these, seven are named as new species. Four others are considered new to science, but insufficient material is available to name them. Published information on a further 11 species is included as is a discussion on phylogenetic trends within the genus.

The Neotropical species of Notalina,a southern group of long-horned caddisflies (Trichoptera: Leptoceridae)*

The leptocerid trichopteran genus Notalina is recorded from the South American continent for the first time. Seven new species are described in it and placed in a new subgenus, Neonotalina: N.brasiliana, N.morsei, N.cipo and N.hamiltoni from southeastern Brazil, comprise the brasiliana species-group, and N.roraima from Venezuela, N.nanay from Peru and N.matthiasi from Colombia form the roraima species-group. Notalina (Neonotalina) is identifiable by the presence of a long, slender baso-mesal process on the male inferior appendage. The two species-groups may be distinguished by the morphology of the male phallus. The historical biogeography of the genus in South America is discussed.     

Report on the Polycystididae (Rhabdocoela, Kalyptorhynchia) from Australia, with the Description of Twelve New Species and Six New Genera

Twelve new species of Polycystididae Graff, 1905 are described from the Australian east coast. Nine of them could not be placed in any of the existing genera, and therefore six new genera are erected. Alchoides n. gen. differs from all other polycystidid genera by the presence of a bundle of glands that opens into the distal part of the male atrium (accessory vesicle type V). Two species are included in the genus, A. alchoides n. sp. and A. dittmannae n. sp., which differ from each other in the shape of the stylet. Ametochus gehrkei n. gen n. sp. can be distinguished from other polycystidids by the presence of a prostate vesicle type III associated with a prostate stylet type III, combined with the presence of an accessory stylet type III, while a prostate stylet type II is lacking. Typical for Arrawarria inexpectata n. gen n. sp. is the combined presence of an armed cirrus with a prostate vesicle type II connected to a prostate stylet type II. Two species are assigned to the new genus Duplexostylus n. gen.: D. rowei n. sp. and D. winsori n. sp. These two species have two unique features: a prostate vesicle type IV directly connected to a prostate stylet type III and an asymmetrical septum that surrounds the proximal part of the male atrium. They can be distinguished from each other by differences in the detailed construction of their stylets. Two new species are placed in the new genus Stradorhynchus n. gen.: S. caecus n. sp. and S. terminalis n. sp. They have unpaired gonads and a prostate vesicle type IV connected to a prostate stylet type IV, which combination of characters makes them unique within the Polycystididae. The two species differ from each other in the shape and size of the stylet. Triaustrorhynchus armatus n. gen., n. sp. is the first species of the Polycystididae to have three types of stylet in the male atrium: a prostate stylet type II, a prostate stylet type III and an accessory stylet type III. Three new species could be placed in existing genera: Cincturorhynchus monaculeus n. sp., Paraustrorhynchus caligatus n. sp. and Polycystis australis n. sp. All three differ from their congeners in the form and dimensions of their stylets. All newly described species are discussed, giving their similarities and differences with resembling species. Austrorhynchus hawaiiensis Karling, 1977 is reported for the first time in Australia, and the Australian population is compared with populations from other regions. The presence of Gyratrix hermaphroditus Ehrenberg, 1831, one new species of Paulodora Marcus, 1948 and a new genus of Typhlopolycystidinae Evdonin, 1977 is mentioned.     

Ighermia, a new genus of the Asteraceae – Inuleae

An aberrant species of the genus Asteriscus (Asteraceae–Inuleae), A. pinifolius from SW Morocco, is here proposed to be removed and placed in a separate, monotypic genus Ighermia. The systematic position and morphology of the new genus are also discussed.     

The agelenid funnel-weaver family and the spider genus Cedicus in Israel (Araneae, Agelenidae and Cybaeidae)

The funnel-weaver spiders of the family Agelenidae in Israel are revised along with spiders of the excluded genus Cedicus , here placed in the Cybaeidae. Although the webs are conspicuous and abundant only very few members of these families have been reported thus far from the East Mediterranean fauna. Altogether 19 species of agelenids are described with detailed diagnostic illustrations, including eight new records and six species new to science. With the biological and zoogeographical information revised and all type and non-type material pertinent to the fauna reexamined, the occurrence of Lycosoides and Maimuna in the Middle East has been verified while Textrix is absent. Agelena is represented only by a single species. Two Mediterranean species are newly placed in Benoitia , and a new genus Agelescape has been erected to accommodate three species. Tegenaria proves to be the largest indigenous genus and includes some of the long-legged spiders in Israel. The relationships of Cedicus and its two species in Israel are addressed. The new species described are: Agelescape gideoni, Maimuna carmelica, M. meronis, Tegenaria mediterranea, T. epacris, T. angustipalpis and Cedicus israeliensis .     

A new genus and species from Borneo and a new species from Java and Sumatra of Cicadini (Hemiptera: Cicadidae)

A new cicada genus and species, Minilomia triquetra, gen. and sp. nov., is described from Borneo. The new genus Minilomia is closely allied to Platylomia Stål and is placed in the subtribe Dundubiina of the tribe Cicadini. Another new cicada species, Pomponia brevicaudata, sp. nov. (subtribe Psithyristriina), is described from Java and Sumatra. The new species belongs to the Pomponia linearis species group and the P. linearis species complex but is distinguished from its congeners by the unusually short male abdomen.

A new genus and two new species of Choniostomatidae (Copepoda) parasitic on two deep sea isopods

The systematic position of the little-deformed parasitic copepod family Nicothoidae to the much deformed family Choniostomatidae has been disputed for many years. The new genus Diexanthema gen. nov., based on Diexanthema desistoma sp. nov. and Diexanthema bathydiaita sp. nov. discovered on two deep-sea asellote isopod species, clearly links the family Nicothoidae (via male Diexanthema) to the family Choniostomatidae (via female Diexanthema). Based upon the extreme sexual dimorphism of this new genus, it is suggested that the family Nicothoidae be dissolved and its members placed within the family Choniostomatidae. It is concluded that the differences seen between these two parasitic groups is probably due more to host adaptations than reflecting any phylogenetic trend that is evolutionarily significant. It is felt that the deep-sea environment may serve as a refugium for archaic copepod forms which may possibly offer additional clues and insights into the phylogeny of the parasitic copepoda.
This investigation suggests that the life history and parasite/host relationships of Diexanthema desistoma are quite complicated and well geared to the life history of its isopod host, Chelator insignis.
