Potamophilops bragaorum sp. nov. is described and illustrated based on adult specimens collected in a mountainous area in the Cerrado biome in Taquaru\ç\ú district, Tocantins state, Brazil. This is the second species described in the genus and it represents the northernmost record of Potamophilops, which is known only from Argentina and Brazil. In this article we provide a diagnosis, details on the morphology and images of the habitus and structures used to determine the species and to distinguish the gender. Field observations permitted the description of some aspects on the biology of the new species that seem to be very similar to those of other Larainae genera. Examination of gut contents revealed a diet based mostly on periphyton.

The genus Austrolimnius Carter \& Zeck has its greatest known diversity in Oceania, but its fauna in the Americas is poorly known. In this paper, two new species\—Austrolimnius uncatus sp. nov. and A. bocainensis sp. nov.\—are described and illustrated based on adult specimens collected at Serra da Bocaina National Park, S\ão Jos\é do Barreiro Municipality, S\ão Paulo State, and Nova Friburgo Municipality, Rio de Janeiro State, Brazil. Austrolimnius uncatus sp. nov. is characterized by the long setae on the mesotarsus, the medial expansion of the hind tibiae, and the hook-like shape of the male genitalia. Austrolimnius bocainensis sp. nov. can be recognized by the absence of setae on the mid-tarsus, the cylindrical hind tibiae, and the slightly curved genitalia with few setae. A pictorial key for the Brazilian species of the genus is given. New records of Brazilian species of the genus are reported.

We provide a review of species of the genus Dryopomorphus Hinton, 1936 occurring in Malaysia. Three known species: D. bishopi Hinton, 1971; D. satoi Spangler, 1985 and D. hendrichi\ {\v C}iampor Jr \& Kodada, 2006 are diagnosed and five new species from the Malay Peninsula and Borneo are described here: D. grandis, D. jaechi, D. memei, D. pekariki and D. sarawacensis. Habitus photographs, drawings of genitalia and diagnostic characters of all species are included.
