Three new species are described in the genus Drymopsalta Ewart, previously known only from D. crepitum Ewart and D. daemeli Distant. The three new species occur in Southern Queensland and Northern Territory. D. wallumi sp. nov. occurs along coastal S.E. Queensland, whereas D. hobsoni sp. nov. is restricted to the Bringalily State Forest, near Inglewood, southern inland Queensland. D. acrotela sp. nov. is found in the Litchfield National Park and other locations near Jabaluka, Cahills Crossing, E. Alligator River and Nourlangie, all across the northern Northern Territory. D. crepitum occurs on the Cape York Peninsular extending into the southern Gulf, while D. daemeli occurs in two localised regions in central coastal N.S.W. Each of the species inhabits heath vegetation, often spilling-over into adjacent tree foliage. The species of Drymopsalta are small and inconspicuous cicadas (<15 mm body length) with relatively high frequency songs (~15 to 22 kHz). The temporal structures of the normal calling songs follow a similar pattern in each species, consisting of the emission of short chirps (comprising 2–16 ticks). Between the chirps are emitted one (D. wallumi, D. hobsoni, D. acrotela), two (D. daemeli) or 1–9 (D. crepitum) intervening single ticks. The species can be distinguished by the timing and the number of these single ticks relative to the adjacent chirps with the notable exception of D. hobsoni and D. acrotela. The calling songs of these two allopatric species are indistinguishable, an unusual feature in Australian cicadas. Two additional song variants are described, a more unstructured chirping song without intervening single ticks observed in each of the species except D. crepitum, and periodic extended buzzing echemes emitted within the calling songs (excepting the D. wallumi song).

Three new species of Anaulacomera are described, Anaulacomera (Anaulacomera) mariellae sp. n. and Anaulacomera (Anallomes) arlindoi sp. n., belonging respectively to the Inermis and Lanceolata species group, and Anaulacomera angelinae sp. n., placed as incertae sedis. The individuals were collected at the Iguaçu National Park and adjacent small fragments of Atlantic Forest, in southwestern Paraná state, Brazil. The description was based on external morphology of males. We also present distribution maps for the species of the Inermis and the Lanceolata species groups.

The Western Australian endemic humicolous beetle genus Tympallopatrum Perkins is revised. A key to the four known species is given. Three new species are described: T. aureolum (12 km W. Walpole, Walpole National Park, Mt. Clare), T. callosum (Beedelup National Park, 20 km W. Pemberton), and T. curvicostum (Porongurup National Park, Bolganup Creek). These rare, markedly sculptured beetles were collected from litter and/or fungi, or by pyrethrin fogging of bark, usually near streams or moist habitats. High resolution digital images of the holotypes are presented (online version in color), male genitalia are illustrated, and geographic distributions are mapped.

We describe three new gecko species of the Paroedura oviceps clade, diagnosed by deep divergences in mitochondrial DNA, absence of haplotype sharing in two nuclear genes (sacs and kiaa1239), and morphological differences. Paroedura spelaea sp. nov. is an extremely slender species from karst habitats in the limestone massif of the Tsingy de Bemaraha National Park in western Madagascar, morphologically reminiscent of P. homalorhina but distinguished by the absence of distinct dorsal rows of spiny tubercles. Paroedura fasciata sp. nov. from the small karstic island Nosy Hara in northern Madagascar is phylogenetically placed sister to P. spelaea despite radical morphological differences. It is morphologically most similar to P. hordiesi from the geographically close Montagne des Français massif, but is smaller, has slightly more spiny dorsal scales, and a distinctive colour pattern with light grey dorsal crossbands. The third species, Paroedura kloki sp. nov., is known from Ankarafantsika National Park and the western slopes of Makira, two sites of dry to transitional forest in western Madagascar. It is at least partly arboreal and morphologically very similar to P. oviceps, from which it differs by spiny scales extending over its entire tail. Although incomplete, the available phylogenetic evidence suggests that the karst specialists in the P. oviceps clade (P. fasciata, P. homalorhina, P. hordiesi, P. spelaea) form a monophyletic group which might have diversified by vicariance after becoming isolated, respectively, in their limestone habitats in Tsingy de Bemaraha, Ankarana, Nosy Hara and Montagne des Français.

Three new species of the nursery-web spider genus Architis Simon, 1898 are described and illustrated; all collected during spider biodiversity inventories in the Brazilian Amazonia. Architis gracilis Santos sp. nov. is based on a male and A. catuaba Santos sp. nov. on a female specimen, both from the state of Acre, western Brazilian Amazonia. Architis neblina Santos & Nogueira sp. nov. is described from eight females from the Pico da Neblina National Park, state of Amazonas. New records from Brazil are listed for Architis brasiliensis (Mello-Leitão, 1940), A. helveola (Simon, 1898), A. maturaca Santos, 2007 and A. tenuipes (Simon, 1898). The presence of cuspule-like spines on male coxae I, once known only for Architis tenuis Simon, 1898 and A. cymatilis Simon, 1898, are reported for A. maturaca. A remarkable dimorphism in the epigynum of Architis capricorna Carico, 1981 is described based on specimens from southern Brazil. An updated identification key for species of Architis is provided.

Three new species in the diatom genus Eunotia were found in the freshwater ponds and streams of Acadia National Park, Maine, USA. Eunotia novaeangliae sp. nov. belongs to the E. incisa group, species with nose-like apices and terminal raphe fissures distant from the ends. It is most similar to E. tenelloides in that species cluster, although differs in the valve shape, geographical distribution, several ultrastructural details and slight but consistent differences in valve dimensions and striae density. Eunotia panda sp. nov. is in the E. bilunaris group, species with slight even curvature and smooth margins of the valves. However, E. panda can be distinguished from E. bilunaris by dorsally slightly recurved apices with rounded ends, ultrastructural details and noticeably constant valve width. Eunotia spatulata sp. nov. is most similar to E. eurycephala, but differs from that taxon by having straighter and significantly larger valves with more swollen apices. All three taxa were sufficiently abundant in the samples collected from the park that they could be found in both SEM and LM microscopes. Eunotia novaeangliae and E. panda have both been illustrated in other publications before but not named. All three species occurred in waters of low conductivity and pH, typical for the genus. Acadia National Park appears to be a hotspot for Eunotia species diversity, and further study of the oligotrophic waters of this site is certainly warranted.

Three new species of oribatid mites of the genus Pergalumna (Oribatida, Galumnidae) are described from litter and soil in the Korup National Park (Cameroon). Pergalumna jenoi sp. nov. differs from P. margaritata Mahunka, 1989 and P. pseudomargaritata Mahunka, 1994 by the presence of simple dorsosejugal suture, dentate anterior margin of the ventral plate, distinct reticulate pattern on the pteromorphs and dense stria on the genital plates, the localization of setal alveoli la posterior to porose areas Aa, and the absence of a median pore. Pergalumna tuberclesejugalis sp. nov. differs from P. margaritata and P. pseudomargaritata by the larger body size, the localization of porose areas Aa closer to lm than la, and setal alveoli h3 close and lateral to A2, the presence of sejugal porose areas, and the absence of a median pore and stria on the genital plates. Pergalumna grebennikovi sp. nov. differs from P. bifissurata Hammer, 1972 by the larger body size, the presence of smooth bothridial setae, well-developed interlamellar setae, reticulate anterior margin of pteromorphs, comparatively long prodorsal median ridge and a median pore, and the localization of setal alveoli la and porose areas Aa. An identification key to the known species of the genus Pergalumna from the Ethiopian region is presented.

AbstractThree new species are described; two European species, tringarius L. and lineola Fabr., are recorded for the first time; and the previously described species are redefined and new distribution records presented, with a key to the eastern species. Rhagio hirtus Loew is recognized as a good species, R. boscii Macquart and Xylophagus fasciatus Say are synonymized with albicornis Say, and R. intermedius Walker is synonymized with R. vertebratus Say. The three new species are R. dichromaticus from Louisiana, recognized by its extremely dark coloration; R. floridensis from Florida and Georgia, with yellow thorax and distinctively patterned wings; and R. orestes from Great Smoky Mountains National Park, which is close to hirtus but separable by the darker thorax and abdomen.
