Australocrinia Heyer & Liem was erected to accommodate the species riparia Littlejohn & Martin and tasmaniensis Gunther. Here I examine these species and determine the systematic status of Australocrinia. Multivariate numerical techniques were employed to sort specimens of the 14 species examined. Ranidella Girard (sensu Heyer and Liem 1976) was shown to be a group of closely related species. Although A. riparia and A. tasmaniensis differ from this group in a number of respects the differences are considered insufficient to warrant the recognition of a genus to accommodate them. Accordingly I refer them to Ranidella. Three species-groups were recognized in Ranidella. One contains all the species referred to Ranidella by Heyer and Liem (1976), whereas R. riparia and R. tasmaniensis are monotypic groups.

The discovery of a new locality yielding giant Guadalupian (Lower Permian) fusulinids in east-central Alaska extends the range of these forms much farther north than previously known, and into a tectonostratigraphic terrane from which they previously had not been reported. The number of areas from which giant parafusulinids are known in North America is thus raised to eight. Three of these localities are in rocks that previously had been referred to the allochthonous McCloud belt arc, and one, West Texas, is known to have been part of Paleozoic North America. Comparison of species from all areas suggests that there are two closely related species groups: one represented in Texas and Coahuila, and the other represented in Sonora, northern California, northeastern Washington, southern and northern British Columbia, Alaska, and apparently in Texas. These groups may differ because they are of slightly different ages or because interchange between the faunas of Texas–Coahuila area and the other regions was somewhat inhibited during the Early Permian.

Three new coprophilous Chaetomium species are described and illustrated: C. subcircinatum from Tanzania, C. retardatum from Kenya and Zaire (Congo), and C. multispirale from Kenya, Canada, and Mexico. Many additional records are provided for 13 previously described species and species groups, several of which are redescribed from pure cultures. A comparison of two closely related species, C. globosum and C. coarctatum, is presented.

First Time

We provide morphological descriptions of the tadpoles of ten species of Malagasy treefrogs of the genus Boophis (family Mantellidae). Based on individuals determined by DNA barcoding, the larvae of eight species are described for the first time: B. anjanaharibeensis, B. axelmeyeri, B. elenae, B. englaenderi, B. luciae, B. rhodoscelis, B. roseipalmatus, and B. vittatus. For two additional species, B. andreonei and B. microtympanum, we provide descriptions from other localities than the previously known larvae. All tadpoles described herein are stream-adapted, exotrophic, and of a relatively generalized morphology. In general, we found a morphological similarity of larvae belonging to phenetic species groups of Boophis, but more detailed analyses showed several differences between taxa that are known to be sister species or closely related to each other: B. luciae has a much higher number of oral papillae than B. sibilans, B. roseipalmatus has a slightly lower number of papillae and possibly a stronger caudal musculature than B. madagascariensis, and B. elenae has a distinctly lower number of oral papillae and keratodonts in the first upper keratodont row than B. sandrae. This indicates that tadpole characters might, in some cases, provide good taxonomic characters in Boophis, a genus in which adults of closely related species are often morphologically extremely similar.

The subgenus Oculogaster Kluge 2016 is divided into two species groups: the «African group» includes Procloeon (Oculogaster) cylindroculum Kimmins 1956, P. (O.) barnardi sp. n., P. (O.) niger sp. n., unnamed species P. (O.) sp. «Wolfkloof» and presumably P. (O.) silvicola Gillies 1997; the «Asian group» includes P. (O.) album Kluge 2016, P. (O.) regularum Müller-Liebenau & Hubbard 1985, P. (O.) malabarensis sp. n., presumably Procloeon julia (Gillies 1949) comb. n. and unnamed species P. sp. «Thailand-3», P. sp. «Sulawesi» and P. sp. «Philippines». New South African species P. (O.) barnardi sp. n. and P. (O.) niger sp. n. are described from South Africa based on larvae, subimagines and imagines of both sexes associated by rearing; among them, P. (O.) barnardi sp. n. was formerly described by Barnard (1932) under the name «Austrocloeon africanum», being wrongly regarded to be the species originally described as Cloeon africanum Esben-Petersen 1913. Characters of larva and female subimago of another South African species, P. (O.) sp. «Wolfkloof» are described based on a single specimen. Two closely related species, P. (O.) regularum Müller-Liebenau & Hubbard 1985 from Sri Lanka and P. (O.) malabarensis sp. n. from India are described based on larvae, subimagines and imagines of both sexes associated by rearing; these two species have 2 (rarely 1 or 3) cross veins in pterostigma, in contrast to other species of Oculogaster which normally have one vein (rarely two veins). Procloeon julia is presumptively placed in Oculogaster based on the presence of one vein in pterostigma. Unnamed species P. sp. «Thailand-3», P. sp. «Sulawesi» and P. sp. «Philippines» are presumably placed in Oculogaster; each is briefly described based on a single larva.

Molecular Comparison

The palaemonid genus Isopericlimenaeus is currently comprised of only the type species, Isopericlimenaeus gorgonidarum, with the diagnostic character of the genus being the presence of a molar and fossa structure on both second chelipeds. Periclimenaeus uropodialis is a closely related species, which has either been considered a synonym of I. gorgonidarum or placed as a valid species in the related genus, Periclimenaeus. During fieldwork in the Philippines, Taiwan and Korea, several species of Periclimenaeus and other sponge associated shrimps belonging to the family Palaemonidae were collected, including I. gorgonidarum and P. uropodialis. Based on a morphological and molecular comparison, it is demonstrated that both taxa are conspecific and that Isopericlimenaeus is a junior synonym of Periclimenaeus.

Examination of differences in phenetic variation between a number of closely related species of mites of the family Phytoseiidae from four widely different environments in North America, ranging from subarctic to subtropical, was undertaken. Phenetic variation was measured by (1) determining the numbers of taxa recorded in given areas as a measure of the richness of species and genera; (2) determining interspecific morphological diversity using multivariate techniques based on frequency distributions of the taxonomic distances between pairs of species; and (3) by using phenogram analyses to determine the species groups in a given area.The results show a consistent trend in the degree of diversity. The more northerly communities have fewer taxa and these show little phenetic diversity, whereas the more southern communities have more taxa and they show greater phenetic diversity.

In this revision of the genus Rhytidoponera on the island of New Caledonia, 18 species are recognized: seven previously described taxa (acanthoponeroides Viehmeyer, atropurpurea Emery, fulgens Emery, numeensis Andre, pulchella Emery, versicolor Brown, and wilsoni Brown) and 11 new species (aquila sp.nov., arborea sp.nov., depilis sp.nov., insularis sp.nov., koumensis sp.nov., litoralis sp.nov., luteipes sp.nov., mimica sp.nov., nitidiventris sp.nov., opaciventris sp.nov., and terrestris sp.nov.). All of these species are endemic (except perhaps terrestris, for which there is a questionable record from Vanuatu), and they segregate into four species-groups: acanthoponeroides group (one species), fulgens group (four species), numeensis group (three species) and pulchella group (ten species). Alate queens have not been found in any species, suggesting that colonies are entirely worker-reproductive. The behaviour and nest architecture of species in the pulchella group indicates specialization as foliage-foragers on understorey and forest edge vegetation, in contrast to the ground-foraging tendencies of the remaining species. Some pulchella-group species are involved in mimicry complexes with other ants and other foliage- frequenting arthropods. Closely related species of New Caledonian Rhytidoponera are usually distributed allopatrically, and conspecific populations exhibit a wide range of morphological differentiation.
