Two new species of Pentacalia are described herein on the basis of morphological evidence. These new findings are the result of field work and recent herbarium studies carried out at USM. Both species are very distinctive and any confusion with the other known taxa of the genus is unlikely. Both species are hitherto only known from the type locality, one collected in Junín Department (central Peru) and the other in Amazonas Department (northern Peru). They grow in Andean humid montane forests. Pictures of the respective holotypes and a distribution map are provided. Moreover, the name P. marinii is synonymized under P. herzogii, as well as P. megaphlebia to P. oronocensis.

The present study tries to focus on describing two new species belonging to genus Gammarus from western Iran along the Zagros Mountains range. The most remarkable feature of Gammarus hegmatanensis sp. n. is the shape of epimeral plate 3, which is sharply pointed posteriorly with a distinct lobate anterior margin. This species has some similarities with and differences from some other species of Gammarus pulex–group such as G. parthicus and G. syriacus. The other species, G. sirvannus sp. n. with elongated eyes is similar to G. duebeni, G. lobifer, G. balutchi and G. loeffleri, but it shows prominent morphological differences and a distinct geographical distribution from these species. These new findings shed more light on the information available on amphipod fauna of Iran.

Two new species of Senecio are described from Peru. One thrives in the high Andes of the southeastern department of Lima and the other one occurs in the lomas vegetation of southern Ica. Both species are compared with the morphologically closest taxa and useful characters for their proper identification are provided. A distribution map, illustrations, and pictures of living plants are also presented.

The diving beetles Liodessus altoperuensissp. nov. and Liodessus caxamarcasp. nov. (Dytiscidae, Hydroporinae, Bidessini) are described from the high altitudes of the Puna regions of north western Peru. They occur in shallow and exposed mossy peatland puddles. We delineate the two species using structures such as male genitalia, beetle size, shape and colour pattern. Mitochondrial Cox1 data were also generated, and revealed clusters congruent with morphological evidence. Altogether fourteen Liodessus species are now known from the Andean region.

Recent collections carried out in southern Colombia (Putumayo) and southern Ecuador (Zamora-Chinchipe) lead us to describe two new species of Pentacalia based on morphological evidence. One of them displays lateral, axillary synflorescences and disciform capitula, whereas the other keys out in the group of terminal synflorescences and disciform capitula. Taxonomically useful characters are provided to easily distinguish each species from its closest relatives, as well as detailed pictures of living plants and distribution maps. Adjusted keys for the Colombian and Ecuadorian species are also presented.

Two new species of the genus Cyrtodactylus are described based on collections from Northeast India, and descriptions and diagnoses of previously described species and synonyms from the region are provided. One of the new species from lowland habitats in Tripura is medium sized, with a continuous series of precloacal pores, and is allied to C. ayeyarwadyensis from Myanmar; while the other new species from West Bengal is smaller, with both femoral and precloacal pores, and is related to C. gubernatoris from West Bengal and Sikkim. We designate a lectotype for Cyrtodactylus khasiensis and recognize the C. khasiensis synonym Gymnodactylus himalayicus as a valid species of Cyrtodactylus based on morphological evidence, and suggest the recognition of the last remaining subspecies of C. khasiensis, C. k. cayuensis, as a valid species based on geography and morphology. The stabilization of the taxa Cyrtodactylus khasiensis and C. gubernatoris with a limited subset of characters and specific distributional data, as well as the elevation of Cyrtodactylus himalayicus comb. nov. from synonymy, will allow the descriptions of many more Cyrtodactylus species from the region.

Two new species of blind ground beetles are described from the southern United States. One species, Anillinus relictussp. nov. (type locality: E of Oneonta, Blount County, Alabama), based on the structure of male genitalia, is similar to Texan Anillinus, in particular to the endogean A. sinuatus Jeannel. The second species, A. felicianussp. nov. (type locality: 4 mi SW Jackson, West Feliciana Parish, Louisiana), is superficially similar to the endogean A. sinuaticollis Jeannel from Roane County, Tennessee, and represents the first record of the genus for the state of Louisiana. All species are illustrated with digital images of habitus, body parts, and male and female genitalia. Biogeographical and evolutionary implications of the new findings are discussed.

The article describes a new genus, Laberlia (type species − Langsdorfia bellaria Dognin, 1911), including three species, distributed in northern and central Andes (the territory of Colombia, Ecuador, and Peru). We establish a new combination: Laberlia bellaria (Dognin, 1911) comb. nov. Two new species are described: Laberlia illapai Yakovlev, Naydenov, Penco sp. nov. (type locality − Ecuador, Morona Santiago, 55 km Road Rio Bamba-Macas) and Laberlia apusorum Yakovlev, Naydenov, Penco sp. nov. (type locality – Peru, La Libertad, Pataz prov., S of Tayabamba). The article is illustrated with images of type specimens and male genital structures, the distribution map is provided.

Two new species of ants belonging to the genus Leptogenys are described: L. academica n. sp., and L. carioca n. sp., both belonging to the crudelis group. The former species is known from the city of Curitiba while the other species occurs in montane forests of the Itatiaia Plateau. We provide descriptions based on the worker caste, images, as well as a modification of the key presently used for identifying the New World workers of Leptogenys.

Two new species of Terebrasabella Fitzhugh & Rouse, 1999 are described from eastern Australia. Terebrasabella hutchingsae sp. nov., was found from preserved coral rock debris collected in 1977 on the outer Barrier Reef near Lizard Island, Queensland. Terebrasabella fitzhughi sp. nov., was found alive in burrows in and among spirorbin serpulid tubes on intertidal rocks in Tasmania in 1996. Both species were found in mucoid tubes, and brood their young in a manner similar to the only other described species of Terebrasabella, T. heterouncinata Fitzhugh & Rouse, 1999. Terebrasabella hutchingsae sp. nov., is exceptional as it possesses a type of thoracic neurochaetal uncinus different from the other two species, and which is similar to the notochaetal acicular “palmate hook” seen in Caobangia. Descriptions of both species are given, and the diagnosis for Terebrasabella is emended. Larval and chaetal morphology and relationships among of the three known Terebrasabella spp. are discussed.
