LV.—A new trilobite,Acidaspis (Pseudomonaspis) magnospina,from the Coniston limestone

Summary

The morphology of adults and young of Acanthomia tomentosicollis Stål. and A. horrida, Germ. is described. Measurements of head-width and antennal segments of nymphs and adults were made. The heads of adults and nymphs of A. tomentosicollis are wider than those of A. horrida. The comparisons of head and antennal growth showed that the two species developed at about the same rate. Some of the morphological features of these species are remarkably primitive and are probably new features known in the Pentatomamorpha.     

Generic status and redescription of the Mediterranean fish Gobius liechtensteini Kolombatovic, 1891 (Teleostei: Gobioidea), and its affinities with certain American and Indo-Pacific gobies

Summary

A new monotypic genus, Corcyrogobius, is proposed for the gobiid fish, Gobius liechtensteini Kolombatovic 1891, known only from its Adriatic typelocality of Kor?ula, Yugoslavia. The species is redescribed and a lectotype designated from probable syntype material, which also includes examples of Odondebuenia balearica (Pellegrin & Fage, 1907), supposed by Kolombatovic to be adults of G. liechtensteini. The affinities of C. liechtensteini and the related genus Odondebuenia are discussed with reference to American seven-spined gobies, the Indo-Pacific Gladiogobius, and the subfamily Lioterinae, currently placed in the Eleotridae. Overall similarities between these gobies are described, their possible phylogeny outlined, and the Lioterinae transferred to the family Gobiidae.     

First record of the genus Tanaostigma (Hymenoptera,Chalcidoidea, Tanaostigmatidae) from the Afrotropical region with description of three new species

The jumping plant-lice (Hemiptera,Psylloidea) associated with Schinus (Anacardiaceae): systematics,biogeography and host plant relationships

The gall-forming psylloid fauna associated with the temperate Neotropical plant genus Schinus (Anacardiaceae) is revised, and keys are provided for adults, larvae and galls. Fourteen species are recognized in the genus Calophya (Calophyidae), 10 of which are described as new; C. gallifex and C. schini are reinstated from former synonymy with C. rubra. An additional closely related new species, C. clavuligera sp. n., is described from Lithrea spp. In the genus Tainarys (Psyllidae, Rhinocolinae), six species are recognized and, for five of these, Schinus species are confirmed hosts. Two of them are described as new and one is recombined from Leurolophus. A new Leurolophus species is described from Lithrea molleoides. Based on a cladistic analysis Pelmatobrachia, Microceropsylla and Neocalophya are synonymized with Calophya, producing five new and one revised species combinations as well as one nomen nov. A list of the 59 currently recognized species is provided with information on synonymy, distribution and host plants. The cladistic analyses suggest that the Schinus inhabiting calophyids form two monophyletic groups, the C. rubra and C. hermicitae groups, respectively. A discriminant analysis of 15 variables for both males and females provides morphometric characters for separating the morphologically very homogenous adults of the C. rubra group. The phylogenetic relationships of the Rhinocolinae are re-evaluated, and the genera Tainarys and Leurolophus are redefined. Notophyllura is transferred from the Euphyllurinae to the Rhinocolinae. Tainarys forms the sister group of Leurolophus + Notophyllura. Based on mapped distributions four areas of endemism (distribution) are defined: A (Eastern temperate South America), B (Central and Southern Chile, including adjacent parts of Argentina), C (Central Argentina) and D (Peru, Far Northern Chile, and Eastern Bolivia). Cladistic biogeographical analyses with TAS, COMPONENT and an algorithm by Enghoff yielded the general area cladogram (A +(C +(B +D))); the one calculated with BPA differed in the position of D: (D +(A +(B +C))). The reconstruction of vicariant events using a protocol by Hovenkamp, corroborates the former general area cladogram, which is compared to competing hypotheses. The history of dispersal and vicariance events is reconstructed with the programme DIVA. Evidence for cospeciation of Schinus with its associated psylloids is evaluated with COMPONENT and TREE MAP. The likelihood for cospeciation is high in the Calophya hermicitae group, but low in the Calophya rubra group and in Tainarys. The gall shape depends partly from the psylloid, partly from the Schinus phylogeny.     

Notes on the ecology of the Clwyd estuary,north Wales

Summary

No previous ecological work having been attempted in the Clwyd estuary, a 13 month survey was made to assess conditions and provide basic data. A notable feature of this estuary is its physical construction, which, being long in relation to its width, appears to limit the diversity of the benthic fauna. Comments are made on the five most abundant species, Macoma balthica, Scrobicularia plana, Nereis diversicolor, Corophium volutator and Gammarus duebeni. The effect of changing climatic conditions on one species, Gammarus duebeni is described.     

First described fossil representatives of the parasitoid wasp taxa Asaphesinae n. n. and Eunotinae (Hymenoptera: Chalcidoidea: Pteromalidae sensu lato) from Eocene Baltic amber

ABSTRACT

New Baltic amber species of Pteromalidae sensu lato are described, from two different subfamilies, Asaphesinae n. n. and Eunotinae. Asaphesinae is provided as a replacement name for Asaphinae Ashmead 1904, which is a junior homonym of the trilobite family Asaphidae Burmeister 1843. Coriotela lasallei gen. n., sp. n.. and Butiokeras costae gen. n., sp. n.. are described as the first known fossil species of Asaphesinae and Eunotinae, respectively. These species establish the minimum known age of both groups in the Eocene. Taxonomic changes are also proposed for some extant species. The genus Desantisiana Neder de Román syn. n.. is found to be a junior synonym of Notoglyptus, and its only described species is transferred as Notoglyptus jujuyensis (Neder de Román) comb. n.. The tribe Calyconotiscini, previously classified in Eunotinae, is abolished and Calyconotiscus Narendran & Saleem is transferred to Pireninae.

Five valid species of Heliconema are recognized: H. heliconema, H. ahiri, H. baylisi, H. brevispiculum and H. longissima.

A new species, H. baylisi is described, and H. heliconema, H. brevispiculum and H. longissima are redescribed.     

Observations on courtship,mating and sexual maturity in Portunus pelagicus (L., 1766) (Crustacea,Portunidae)

Summary

Larvae of Alpheus heterochaelis from North Carolina hatch from large eggs as advanced zoeae, usually moult three times, and exhibit almost no linear growth during a short (4 days at 25°c) larval development. Stage I lasts 6 hours at most and is sometimes skipped; III lasts about twice as long as II. Individuals simultaneously exhibiting characteristics of Stage III and the postlarva were occasionally seen. The three zoeal stages and postlarva are described in detail and illustrated. Stages in embryonic and juvenile development and the hatching process are briefly described.

An ‘extended’ pattern of larval development, characteristic of most alpheid species, is described in a general way, and the ‘abbreviated’ development of A. heterochaelis compared to it. At hatching, A. heterochaelis larvae bear rudimentary pereiopods and pleopods; other structures are at the same level of development in both patterns, but subsequent morphogenesis is faster in A. heterochaelis. Larval development of Synalpheus spp., some of which exhibit extreme abbreviation or direct development, is briefly described with reference to the A. heterochaelis pattern.

Nesting behaviour of Australian wasps of the genus Sphex (Hymenoptera,Sphecidae)

Summary

Nests and prey are described for three species of Australian Sphex: cognatus Smith, ephippium Smith, and bilobatus Kohl. All three prey upon Tettigoniidae. The first two make relatively deep, multicellular nests and make open, accessory burrows beside the true nest entrance; however, these accessory burrows are absent in some populations of cognatus. The nests of bilobatus are shallow and contain only one or two cells. Briefer notes are presented on two species of the related genus Prionyx: globosus (Smith) and saevus (Smith); these are predators on Acrididae.

A new species of Cladochaeta Coquillett, 1900 (Diptera: Drosophilidae) associated with Sphodroscarta trivirgata (Amyot & Serville, 1843) (Auchenorrhyncha: Aphrophoridae) from the Brazilian Amazon rainforest

ABSTRACT

A new species of Cladochaeta Coquillett, 1900 (Diptera: Drosophilidae) is described, C. amorimi nov. sp. based on a series obtained from pupae associated with nymphs of Sphodroscarta trivirgata (Amyot & Serville, 1843) (Auchenorrhyncha: Aphrophoridae) collected on the National Forest of Caxiuanã in the Brazilian Amazon, State of Pará. The new species belong so the dykra species group, being closely related to Cladochaeta erecta Grimaldi & Nguyen, 1999.

The Conidae (Mollusca: Gastropoda) of India

Summary

The polyp and immature medusa stages of Cladonema californicum Hyman, are described. The life cycle of the species was observed in the laboratory and took about 47 days to complete under laboratory conditions. Field collections from Bodega Harbor indicated that the medusae and reproductive polyp are present all year. A review of the taxonomy of the genus reveals that there are possibly only two valid species of Cladonema if one bases species separation on the medusa alone: C. radiatum and its ‘varieties’, and C. californicum. Additional work is needed to elucidate the relationships among the described varieties of the medusae of C. radiatum and the morphology of their respective polyps before further revision of the genus can be attempted.     

New species of Orasema (Hymenoptera: Eucharitidae) from Central and South America

ABSTRACT

Six new species of Orasema are described. Four species are placed into a newly recognised lasallei species group: Orasema lasallei sp. nov. (Costa Rica, Honduras, Mexico, Nicaragua), O. janzeni sp. nov. (Costa Rica), O. peckorum sp. nov. (Brazil) and O. vasquezi sp. nov. (Colombia). One species is placed in the wayqecha group, Orasema masneri sp. nov. (Ecuador). One other species is currently unplaced to species group, O. longinoi sp. nov. (Costa Rica). Orasema lasallei was taken from a nest of Pheidole vorax (Fabr.) and an undescribed species near O. longinoi from a nest of Pheidole dossena Wilson (Myrmicinae). The morphology of the digitate labrum is discussed with respect to other Eucharitidae.

Four species, A. zebrinum, A. omum, A. seyrigi and A. hancocki, are described as new and three new synonymies are proposed. A. leucostomum (Cameron) is newly transferred to Agrypon. Notes on the phylogeny of the species are included.     

Rediscovering Dichotomius foveicollis (Kirsch, 1871) (Coleoptera: Scarabaeinae), new combination,revalidation and other taxonomic notes

ABSTRACT

We found that Pinotus foveicollis synonym of D. agenor, does not belong to this group of species, neither is synonym of D. agenor. Here the species is revalidated to Dichotomius (Luederwaldtinia) foveicollis, the female is re-described, and the male is described for the first time. Based on male diagnostic characters the species is moved from D. agenor to D. inachus species-group.
