Three noteworthy mirine plant bugs inhabiting subalpine zones of the Nepalese Himalayas (Hemiptera: Heteroptera: Miridae: Mirinae)

Three unique mirine plant bugs inhabiting typical subalpine vegetation in the Nepalese Himalayas are documented, with their confirmed plant associations. A new genus and new species, Khumbumiris schwartzi, is diagnosed and described, based on a male specimen collected from Abies spectabilis; two additional new species, Lygocoris laligurans (associated with Rhododendron shrubs) and Phytocoris sagarmathanus (Abies spectabilis), are also described. Images of the habitats and live individuals are also provided. The tribal placement of Khumbumiris is discussed in detail.

Scientific heritage: Reflections on its nature and new approaches to preservation,study and access

Scientific heritage can be found in every teaching and research institution, large or small, from universities to museums, from hospitals to secondary schools, from scientific societies to research laboratories. It is generally dispersed and vulnerable. Typically, these institutions lack the awareness, internal procedures, policies, or qualified staff to provide for its selection, preservation, and accessibility. Moreover, legislation that protects cultural heritage does not generally apply to the heritage of science. In this paper we analyse the main problems that make scientific heritage preservation so difficult to address. We discuss the concept and present existing preservation tools, including recent surveys, legislation, policies, and innovative institutional approaches. We briefly analyse two recent initiatives for the preservation of scientific heritage, at the Universities of Lisbon and Cambridge.     

Description of four new species of the genus Ampelisca (Amphipoda,Ampeliscidae) from the northeastern and southeastern coasts of Brazil and designation of a neotype for Ampelisca soleata Oliveira, 1954

The present study raises the number of Ampelisca species recorded from the Brazilian coast from 18 to 21. The amphipod fauna of the Brazilian northeast coast is hardly known compared to that of the southeast coast. In this study, we describe three new species from the northeast coast: Ampelisca pseudobicarinata sp. nov., Ampelisca rocasensis sp. nov. and Ampelisca cristianae sp. nov, recorded previously as Ampelisca aff. lobata (Serejo et al. 2000 Serejo, CS, Wakabara, Y and Valério-Berardo, MT. 2000. Taxonomy and geographic distribution of Ampelisca (Amphipoda: Gammaridea) from the Brazilian coast. Polsk Archiw Hydrobiol., 47(3–4): 495–510.  [Google Scholar]). We also report a new record of Ampelisca burkei Barnard and Thomas, 1989 Barnard, JL and Thomas, JD. 1989. A new species, Ampelisca burkei, (Crustacea, Amphipoda) from Florida. Proc Biol Soc Washington., 102(2): 375–384.  [Google Scholar]. From the southeast coast a new species Ampelisca angraensis sp. nov. is described. An obscure species, Ampelisca soleata, which is very similar to Ampelisca brevisimulata, is herein redescribed and a neotype is designated. An updated key with all species of Ampelisca recorded from the Brazilian coast and comments on geographic distribution are given.     

Two new species of Phylactella (Bryozoa Cheilostomatida) from the Mediterranean area belonging to the P. labrosa (Busk) complex of species

Examination of fossil and Recent specimens from the Sicilian area belonging to the Phylactella labrosa ‘complex’ revealed two new species: P. mediterranea sp. nov., a Pleistocene-to-Recent taxon and P. megarensis sp. nov., from Pleistocene sediments from eastern Sicily. Ecological, geographical and stratigraphical distribution of both new species are discussed also in comparison with P. labrosa.     

The identity of Yoldia micrometrica Seguenza, 1877 and three new deep-sea protobranchs from the Mediterranean (Bivalvia)

Three new species are described from the relatively well-known deep Mediterranean protobranch fauna. Yoldiella wareni n. sp. is a miniaturized species so far misidentified as Yoldiella micrometrica (Seguenza, 1877), which is a Pleistocene species (neotype here designated). Yoldiella ovulum n. sp. is similar to Y. micrometrica, of which it may represent a descendant species. Ledella marisnostri n. sp. is the second species known for the genus in the Mediterranean. These three species are thought to be endemic to the Mediterranean, where they may represent either persisting Plio-Pleistocene species which survived the changes from psychrospheric to homeothermic conditions, or newly adapted species, evolved from Plio-Pleistocene ancestors. In the second case, they seem to be the result of an ongoing differentiation of the deep Mediterranean protobranch fauna from the North-East Atlantic one, due to the physical isolation of the Mediterranean basin.

A new genus and species of Pteromalidae (Hymenoptera,Chalcidoidea) from Spain,parasitic in cynipid galls on Fumaria

Neaylax versicolor (Hymenoptera, Cynipidae), which forms galls on fumitory (Fumaria), is attacked in Spain by Rivasia fumariae, a species of Pteromalidae (Hymenoptera, Chalcidoidea) herein described as new and assigned to a new genus. The new genus has an unusual combination of morphological characters but seems best placed in the pteromalid subfamily Ormocerinae. An account is given of the biology and larval morphology of the new species.
