Revision of the West Palaearctic species of Rhoptromeris Förster, 1869 (Hymenoptera: Figitidae: Eucoilinae)

The West Palearctic species of Rhoptromeris are revised. A total of 11 species are recognised as valid in this region, including four newly described species: Rhoptromeris dichromata sp. nov., Rhoptromeris koponeni sp. nov., Rhoptromeris leptocornis sp. nov. and Rhoptromeris macaronesiensis sp. nov. Eucoila luteicornis Ionescu, 1959 is synonymised with Rhoptromeris heptoma (Hartig, 1840) syn. nov. A checklist of the Holarctic Rhoptromeris is presented and an identification key to the West Palearctic species is provided. www.zoobank.org/urn:lsid:zoobank.org:pub:8164332C-93E2-4E3F-A408-F5FF5DFB366E     

Amerozercon Halašková, 1969 species (Acari: Mesostigmata: Zerconidae) of the United States of America

During the study of rich material collected in the USA, six Zerconidae species were found which seem to belong to the genus Amerozercon Hala?ková, 1969 Hala?ková, V. 1969. Some new species of the family Zerconidae from North America (Acari: Mesostigmata). Acta Soc Zool Bohem, 33: 115–127.  [Google Scholar]. Four of them, Amerozercon annularis sp. nov., Amerozercon auricularis sp. nov., Amerozercon halaskovae sp. nov. and Amerozercon penicillatus sp. nov. proved to be new to science.

Acta Soc Zool Bohem, 33: 115–127.  [Google Scholar], is described. Amerozercon minimus (Sellnick, 1958) is redescribed and transferred from the genus Zercon C. L. Koch, 1836 to Amerozercon. Some remarks on the problems of the present Zerconidae systematics are discussed.     

Another inordinate fondness†: diversity of the tanaidacean fauna of Australia,with description of three new taxa

The shallow-water tanaidacean fauna of the Bass Strait has been the subject of recent intensive studies. The present paper extends this work into the deeper waters of the region, describing two new species and one new genus. The new species of the genus Paradoxapseudes has a combination of three maxillule palp setae, no plumose setae on the basis of pereopod 1 nor proximal serration on the antennal peduncle. The second species represents a new genus of the family Anarthruridae, having six marginal setae on the third maxilliped palp article and spines on the merus and carpus of the anterior pereopods. The high diversity of Tanaidacea in Australian waters is discussed. In particular, we conclude that Australian coasts suffer a diversity of immigration routes, have sufficient marine longevity, and afford such a diversity of available niches to have allowed multiple colonization and subsequent allopatric speciation of Tanaidacea. http://www.zoobank.org/urn:lsid:zoobank.org:pub:EE309A5A-E06D-416F-95BD-4C8D0D2BEB97     

Revision of the hirsuticornis‐like species of Macrothrix Baird, 1843 (Cladocera: Anomopoda: Macrothricidae) from Subantarctic and temperate regions of the southern hemisphere

The aim of this paper is to revise populations of Macrothrix cf. hirsuticornis (Cladocera: Anomopoda: Macrothricidae) from different regions of the southern hemisphere. It is demonstrated that M. hirsuticornis Norman and Brady, 1867 Norman, A. M. and Brady, G. S. 1867.

All populations in the southernmost portion of continental South America, Tierra del Fuego, Falklands, South Georgia, South Orkney Islands, and on the Antarctic Peninsula belong to M. oviformis Ekman, 1900 Ekman, S. 1900.

[Crossref] , [Google Scholar], previously known only from Tasmania, is found on Macquarie Island too. Differences between species from the southern hemisphere and Palaearctic M. hirsuticornis are summarized. It is demonstrated that characters of the general body shape (i.e. presence of a hood or a tooth on posterior head border) have a limited value for the systematics of Macrothrix. In contrast, some fine details, mostly missed by previous authors, are valuable for species discrimination. The present study increases the number of species recorded from the Antarctic‐Subantarctic region. Probably, the current pattern of Macrothrix distribution results from a disruption of a pan‐continental (early Mesozoic?) species complex.     

Redescription of Valdivianemertes valdiviae (Bürger, 1909) (Nemertea: Hoplonemertea: Cratenemertidae) and designation of neotype

A century ago Bürger described the species Drepanophorus valdiviae from a single specimen taken from 155 m off the southern tip of Africa by the research vessel Valdivia during the German Deep Sea Expedition. Stiasny-Wijnhoff in 1923 Stiasny-Wijnhoff, G. 1923. On Brinkmann's system of the Nemertea Enopla and Siboganemertes weberi n. g. n. sp. Q J Microsc Sci., 67: 627–669.  [Google Scholar] transferred this species along with Amphiporus stannii (sensu Bürger 1895 Bürger, O. 1895. Die Nemertinen des Golfes von Neapel und der angrenzenden Meeres-Abschnitte. Fauna und Flora des Golfes von Neapel, 22: 1–743.  [Google Scholar]) to a new genus Valdivianemertes but did not mention a family affiliation. In 1993 Crandall transferred this genus to the family Cratenemertidae. During the Spanish Antarctic Expedition BENTART 2003, carried out on board the RV Hespérides, we found one specimen identified with certainty as Valdivianemertes valdiviae, at 602 m depth in the Bellingshausen Sea (Antarctica). As there is no extant holotype, we here redescribe this species from this new specimen and designate it the neotype of this species; photomicrographs of the different regions of the body and the proboscis structure are provided for the first time.     

Tanaidacea (Crustacea: Peracarida) of the North-east Atlantic: the genera Leptognathioides and Portaratrum of the ‘Atlantic Margin’

The tanaidomorphan genera Leptognathioides and Portaratrum from the Benthic Invertebrates of Icelandic waters (BIOICE), Marine Benthic Fauna of the Faroe Islands (BIOFAR), and Atlantic Frontier Environmental Network (AFEN)-related surveys are examined. The diagnosis for Leptognathioides polita is amended and additional size data are given. A new species, L. biarticulata, is described although the differences from L. polita are slight. It occurs in the bathyal Iceland Basin with a distribution that does not overlap with that of L. polita. A new species of Portaratrum, P. holdichi, is described and the apparent similarities (parallelisms) between this former colletteid genus and the akanthophoreid Chauliopleona are discussed. The distribution and rarity of both genera in the region are analysed, Leptognathioides being more common in the cold-water areas or along the cold–warm interface. Portaratrum holdichi n. sp. is more common and abundant in the Rockall-Biscay region of the NE Atlantic.

Earthworms (Annelida: Oligochaeta) of Sao Tomé

During a soil zoology expedition to Sao Tomé Island, among other members of the soil fauna, earthworms were collected. During this collecting trip some 170 earthworm specimens belonging to 18 species were gathered of which two, Dichogaster (Diplothecodrilus) coeruleoviridis and Dichogaster (Diplothecodrilus) zicsii, proved to be new to science. In addition, a small sample from the same locality was also examined and Dichogaster (Dichogaster) thomeana Cognetti, 1910 Cognetti de Martiis, L. 1910. Lombrichi raccolti dal Cav.

Revision of ‘Horatia’ snails (Mollusca: Gastropoda: Hydrobiidae sensu lato) from South Caucasus with description of two new genera

Four nominal species of the genus Horatia Bourguignat, 1887 were described by Russian authors from Caucasian caves (H. borutzkii Shadin, 1932, H. birsteini Starobogatov, 1962, H. ljovushkini Starobogatov, 1962 and H. sokolovi Starobogatov, 1962). Hitherto all the species were known from type series (presented by empty shells) only. Examination of newly obtained samples from the caves of South Caucasus has shown that the four species actually do not belong to the genus Horatia due to obvious differences in the morphology of the copulatory organs between H. klecakiana Bourguignat, 1887 (the type species of this genus) and the Caucasian snails. Moreover, statistical analysis of conchological variation has revealed that the species H. birsteini, H. ljovushkini, and H. sokolovi are conspecific. Two genera are described: Pontohoratia (includes P. birsteini and P. smyri sp. nov.) and Motsametia (with the single species M. borutzkii comb. nov.). The two genera can be distinguished on the basis of the structure of their copulatory organs. The distribution and ecology of the Caucasian Horatia-like mollusks are briefly outlined.

Local floras of the southwest, 1920–1980: an annotated bibliography

Local floras, that is, plant lists for relatively small areas, are widely scattered, often unpublished, and difficult to locate. Over 100 local floras from the southwestern United States (Arizona, Colorado, Nevada, New Mexico, and Utah) are listed and briefly annotated.     

Four new species of the genus Trichomyia − subgenus Septemtrichomyia Bravo (Diptera: Psychodidae: Trichomyiinae) from Brazil

Septemtrichomyia Bravo is a subgenus of Trichomyia Haliday in Curtis that includes 14 Neotropical species. Here we describe four new species of moth flies from the state of Espírito Santo in Brazil: Trichomyia capixaba sp. nov., T. gabia sp. nov., T. gustavoi sp. nov. and T. menezesi sp. nov. We also provide an updated key to males of the subgenus Septemtrichomyia.

Camera traps capture images of predators of Caiman crocodilus yacare eggs (Reptilia: Crocodylia) in Brazil’s Pantanal wetlands

Camera traps were set up in forest nests in 2009, 2010 and 2012 to capture images of possible predators eating eggs of the Pantanal caiman, Caiman crocodilus yacare. We monitored 57 caiman nests; 42 nests were opened and the eggs were counted (mean = 25 eggs/nest, SD = 4.3). Females were present and captured at 38 of those nests. The remaining 15 nests were used as controls, and we did not capture the females or open the egg cavities of these nests. Most of the nests had the eggs eaten by predators, in both the disturbed group (38 nests) and the control group (13 nests). The main predators were carnivorous mammals, such as crab-eating foxes (Cerdocyon thous), coatis (Nasua nasua) and tayras (Eira barbara), although feral pigs (Sus scrofa) and armadillos (Dasypus novemcinctus) were also photographed eating caiman eggs. The lizard Salvator merianae was photographed eating eggs of two nests.     

Host–parasite relationships and life cycles of cuckoo wasps in agro-ecosystems in Argentina (Hymenoptera: Chrysididae: Chrysidini)

Chrysididae is a diverse group of parasitoid/cleptoparasitic wasps; however, host–parasite relationships and life cycles of few species have been studied. Nests of different wasp and bee species were obtained during a trap-nesting programme, in the Pampean region. Some of these nests were parasitised by cuckoo wasps females of Caenochrysis taschenbergi (Mocsáry), Chrysis boutheryi (Brèthes), C. saltana Bohart, C. sp. 1 (ignita-group), C. sp. 2 (ignita-group), Neochrysis lecointei (Ducke), Pleurochrysis ancilla (Buysson) and P. lynchi (Bréthes). This paper reports new data about host–parasite relationships and life cycles for these species. Multiple parasites (from one species or from different families of insects) emerged from single cells of some parasitised nests: from each host cell parasitised by species of Pleurochrysis, two adults emerged successfully, information previously unknown for the genus; and in three cases of cells parasitised by C. boutheryi, two adults successfully emerged from a single cell; in two cases both individuals were chrysidine, and in third one was chrysidine and one Leucospis pulchripes (Leucospidae).     

The Tanaidacea (Crustacea,Peracarida) of the North-East Atlantic: the shelf and bathyal Paratyphlotanais of the ‘Atlantic Margin’

Increasing oil-exploration activity and associated ecological surveying west of the Shetlands is leading to the discovery of many poorly known or undescribed tanaidaceans. Three species of the typhlotanaid genus Paratyphlotanais Kudinova-Pasternak and Pasternak, 1978 Kudinova-Pasternak R. K Pasternak F. A 1978 Deep sea Tanaidacea collected from the Caribbean Sea and Puerto Rico trench during the 16th cruise of RV ‘Akademik Kurchatov’ and the resemblance between the fauna of deep-sea Tanaidacea of the Caribbean region and the Pacific Trudy Instituta Okeanologiii. Akademiya Nauk SSSR, 113, 115–135 (in Russian)  [Google Scholar] have been recorded from shelf and bathyal depths between Iceland, the Faroe Islands and the western margin of the British Isles. Two, P. gracilipes (Hansen) and P. microcheles (G. O. Sars), formerly belonging to the genus Typhlotanais, are redescribed and a new species is described. A key to their identification is included. Inhabiting largely discrete zoogeographic areas, these species help define regional macrofaunal associations.
