Les Caridea (Crustacea: Decapoda) des Herbiers de Phanérogames Marines de Nouvelle-Caledonie (Région de Nouméa) (Systématiquee, écologie, variations Nycthémèrales et vicariance) Naturalis
Ledoyer, M..
This study deals with Caridean fauna living between the leaves of New-Caledonian seagrassmeadows (Cymodocea sp. principally) from zero to about eight meters and sampled during day and night. Twenty species (all figured) were caught (excluding Alpheidae). All are known. Nevertheless, in some cases, small variations have been observed by comparison with the same species from other areas. Presently, 70 species are recognized from New-Caledonian marine waters, including the 17 species reported in this papier for the first time from that region. Comparison with Caridean fauna of seagrass-meadows of other areas (Australia, Japan, Madagascar) shows a very important resemblance between them.

Spatial and temporal distribution of caddisfly larvae in two lowland streams in The Netherlands (Trichoptera) Naturalis
Franken, R.J.M.; Klutman, A.G.M.; Tempelman, D..
Caddisflies are a species rich insect order. The adults are moth-like, but their wings bear hairs instead of scales. The larvae are aquatic and live in self-constructed cases, made of plant material, sand or debris. The species are used as indicators of water quality, but much is still not known about their biology and ecology. In this paper the preferred substrates and phenology of the larvae of 13 species are described, using the data of a survey of two lowland streams in the east of the Netherlands.

An Annotated Checklist of the Vascular Flora of Guinea-Bissau (West Africa) Naturalis
Catarino, L.; Martins, E.S.; Pinto Basto, M.F.; Diniz, M.A..
A Checklist of Guinea-Bissau’s vascular flora is presented, based on the inventory of herbarium material and on recent collections. In addition to the name, we cite for each taxon the basionym and synonyms, the life form and habitat, as well as the chorology, Raunkiaer’s biological type, phenology and vernacular names if known. 1507 specific and infra-specific taxa were recorded, of which 1459 are autochthonous, belonging to 696 genera. This shows a higher diversity than the 1000 species estimated so far. In the autochthonous flora there are 22 species of Pteridophyta from 14 families; 1041 taxa of Dicotyledons from 107 families, and 396 taxa of Monocotyledons belonging to 33 families. Three taxa are probably endemic to the country.

First Indonesian record of Fungiacava eilatensis Goreau et al., 1968 (Bivalvia: Mytilidae), endosymbiont of Fungia spp. (Scleractinia: Fungiidae) Naturalis
Hoeksema, B.W.; Achituv, Y..
The mytilid bivalve Fungiacava eilatensis Goreau, Goreau, Neumann & Yonge, 1968, previously mistakenly referred to as F. eilatensis Soot-Ryen, 1969, is reported for the first time from Indonesia. It lives as an obligate endosymbiont of mushroom corals, particulary Fungia spp., reef-dwelling corals restricted to the tropical Indo-Pacific. Notes are given on its association with different host species, its habitat, its biogeography, and its possible competition with endosymbiotic gastropods belonging to the genus Leptoconchus (Coralliophilidae).

Dischidia (Apocynaceae, Asclepiadoideae) in Laos and Vietnam Naturalis
Livshultz, T.; The Bach, Tran; Bounphanmy, Somchanh; Schott, D..
Two new species, Dischidia dohtii Tran & Livsh. and D. cornuta Livsh., are described and illustrated. Dischidia rimicola Kerr is illustrated for the first time. All three species are associated with treenesting ants of the genus Crematogaster. Presentation experiments with seeds of D. rimicola indicate that they are attractive to the ants. The possible affinity between D. dohtii and the enigmatic D. khasiana Hook.f. from north-eastern India is discussed; D. khasiana is lectotypified. A key to the 14 species of Dischidia documented from Vietnam and Laos and a list of exsiccatae are provided.

Ecology and distribution of Lycopodiaceae Mirbel in Malaysia Naturalis
Rusea, G.; Claysius, K.; Runi, S.; Joanes, U.; Haja Maideen, K.M.; Latiff, A..
This paper is the first account to discuss the distribution, ecology and habitats of the Lycopodiaceae in Malaysia. Lycopodiaceae are widely distributed throughout Malaysia with respect to altitudes and environmental conditions but most abundantly found in hill forest and lower montane forest, terrestrial as well as epiphytic, in shaded or semi-shaded places with relatively high humidity. Pahang in Peninsular Malaysia and Sabah in Borneo have the highest species diversity in terms of the number of species collected.

Herinneringen aan een reis naar Sint-Helena (2) Naturalis
Hartog, J.C. den.
St.-Helena, waar Napoleon zijn einde vond, is maar een klein eiland. Toch ontwikkelde zich er in de loop van de evolutie een aantal merkwaardige eilandvormen, zowel bij de planten als de dieren. Helaas zijn er daarvan verloren gegaan door ernstige fauna- en floravervalsing.

Integrative taxonomy reveals an unexpected diversity in Geastrum section Geastrum (Geastrales, Basidiomycota) Naturalis
Zamora, J.C.; Calonge, F.D.; Martín, M.P..
A revision of the classification of Geastrum sect. Geastrum is presented on the basis of an integrative taxonomic approach, which involves the study of morphological, molecular, ecological, and chorological data. Four DNA regions are analysed: the ITS and LSU nrDNA, rpb1, and atp6. Phylogenetic reconstructions include 95 ingroup samples and show five main clades, which are considered as five subsections, one of them proposed as new (G. subsect. Hungarica), and a total of 27 lineages recognizable at species level. Discriminant function analyses, ANOVAs and Tukey’s HSD tests on more than 500 basidiomata reveal the utility of several quantitative morphological characters for species delimitation. As a result of the combination of the different sources of...

Morphology, Ecology and Biogeography of the South American Caecilian Chthonerpeton Indistinctum (Amphibia: Gymnophiona: Typhlonectidae) Naturalis
Gudynas, E.; Williams, J.D.; Mercedes Azpelicueta, M. de las.
This study of Chthonerpeton indistinctum (Reinhardt & Lütken, 1861) considers 25 morphometric characters, teeth-counts and sex, based on 96 specimens. A multivariate analysis of characters and comparisons of geographically arranged samples is carried out by graphic and statistical methods. No trends in geographical variation were found. Subsequently a redescription of the species is presented, including measurements and counts. Sexual dimorphism was observed for four characters related to the cloacal region. The results are discussed and compared with previous reports. Character-variation is also studied. Primary annuli counts show very low variation; sample variation profiles were similar for the remaining characters. A revision of biological data...

The Old World species of Boehmeria (Urticaceae, tribus Boehmerieae). A taxonomic revision Naturalis
Wilmot-Dear, C.M.; Friis, I..
This is the second part of a world-wide revision of the genus Boehmeria, the previously-published part having dealt with the New World species. The Old World species are widely distributed in the tropics and subtropics from West Africa to islands in the Pacific Ocean and from Japan and China to Southern Africa, Madagascar and Australia, with the highest species richness in the Himalayas and their extension into China and Indochina. No indigenous species is common to both the Old and New World. The species represent taxonomic units of very different complexity: most species exhibit little infraspecific variation; in several others formal taxonomic infraspecific units can be recognised; however, in two, B. virgata and B. japonica, a highly complex variation...

A black, non-troglomorphic amphibian from the karst of Slovenia: Proteus anguinus parkelj n. ssp. (Urodela: Proteidae) Naturalis
Sket, B.; Arntzen, J.W..
A morphologically distinct cavernicolous salamander Proteus anguinus from southeastern Slovenia (Bela Krajina) is described as P. a. parkelj ssp. n. It differs from P. a. anguinus in a dark pigmentation, fully developed eyes, a skull with broader and shorter bones and fewer teeth, a voluminous jaw musculature that gives the head a bulky appearance, a proportionally longer trunk with a higher number of vertebrae, shorter extremities, and a shorter tail. Most of these traits are considered to be plesiomorphic character states. An allozyme analysis over 40 loci has shown the new dark pigmented taxon to be genetically similar to a white and troglomorphic neighbouring population from Stična (DNei = 0.23). Both populations in turn are genetically dissimilar to a...

In memoriam Prof. Dr J.T. Wiebes (1931-1999), evolutionary biologist and systematic entomologist Naturalis
Bruggen, A.C. van; Achterberg, C. van.
Born on 13 September 1931 in Rotterdam, Jacobus Theodorus [Koos] Wiebes read biology at Leiden University where he obtained his Ph.D. in 1963 on studies of Indo-Australian fig wasps. He started working on spiders (Lycosidae, Pisauridae) and beetles (Carabidae, Cetoniidae, Helodidae), but he earned his scientific reputation as a specialist in fig wasps (Hymenoptera: Agaonidae, Torymidae), their parasitoids and intricate host relationships (1961-1994: 89 papers). He served for many years on the staff of the Rijksmuseum van Natuurlijke Historie, Leiden (1955-1970, initially as assistant, later as curator of Coleoptera and as assistant director since 1965), to return as director of the newly merged national zoology and geology museums (ad interim 1982-1984,...

Hydroids from French Polynesia with notes on distribution and ecology Naturalis
Vervoort, W.; Vasseur, P..
INTRODUCTION Distribution and ecology of hydroids from coral reefs of high islands and atolls of French Polynesia so far have received little attention. Redier (1967, 1971) published a preliminary list of 14 species from Salvat's collections, sampled during several trips to Tahiti, Tuamoto (Mururoa, Reao and Maturei Vavao Atolls), to the Australes Islands (Rapa) and to Gambier. The present paper results from researches carried out by one of us (P.V.) concerning the benthic bionomy of reef sciophilous communities of hard bottoms. They have been carried out at Tiahura, Moorea, Society Islands (fig. IA) and on Takapoto Atoll, Tuamoto Archipelago (fig. 2A) in 1973 and 1974. They gave us occasion to compile a revised list of about 22 species of hydroids...

The rediscovery of Cervera atlantica (Johnson, 1861) (Cnidaria: Octocorallia): notes on its identification, ecology and geographical distribution Naturalis
Williams, R.B..
Cervera atlantica, a small stoloniferan octocoral, was described as Cornularia atlantica by James Yate Johnson in 1861 from Funchal, Madeira. It then remained unrecognized until 1972 when I discovered it on the Mediterranean coast of Spain. I have since confirmed its existence at the type locality and have traced its distribution around Madeira, throughout the Canary Islands, and on Portuguese and English coasts. In the Mediterranean Sea, I have found it along Spanish and French coasts, among the Balearic Islands and on the coast of Cyprus. Cervera atlantica is cryptic and photophobic, living under stones in shallow water (usually at 0-2 m) or in crevices and caves in massive intertidal rocks, protected from direct sunlight. Intolerant of rough water, it...

A revision of the Heteropteryginae (Insecta: Phasmida: Bacillidae) of Borneo, with the description of a new genus and ten new species Naturalis
Bragg, P.E..
The three tribes of Heteropteryginae Kirby, 1896 occurring in Borneo are nocturnal, and ground dwelling species, easily found in both primary and secondary rainforest. The subfamily is reviewed, with keys and redescriptions of all Bornean species; one new species of a predominantly Bornean genus is described from the Philippines. Lectotypes have been selected for a number of species. The eggs of 17 species are described and illustrated. Distribution maps are given for all species. Many of the species have been collected by the author and reared in the United Kingdom; some observations on their natural history and behaviour are included. In the tribe Heteropterygini the synonymy has been re-examined with a revision to the status of several taxa. The five...
