Two new species of Hydroptilidae from Pará, Brazil, are described and illustrated: Costatrichia inaequalis sp. nov. is a distinctive species characterized principally by the lateral processes on tergum IX rounded and each bearing a long dorsal seta. Oxyethira carajas sp. nov. is characterized by the inferior appendages fused, incised mesally, narrowing posterolaterally, and each bearing a stout apical seta and having its ventral process blade-like. New distributional records are given for a species of Neotrichia for which the name is unpublished.

Based on nymphs collected in Espírito Santo and Amazonas, Southeastern and Northern Brazil, two new species of the genus Rivudiva Lugo-Ortiz & McCafferty, 1998 (Ephemeroptera: Baetidae) are described. Rivudiva inma sp. nov. shares several characteristics with R. minantenna Lugo-Ortiz & McCafferty, 1998, but can be distinguished by details of leg setation, such as length and shape of robust setae and presence of setae on trochanter. Rivudiva oonirikoperi sp. nov. is more similar to R. trichobasis Lugo-Ortiz & McCafferty, 1998, but can be separated by the absence of setae on scape and pedicel, shape of distal margin of labrum, and length of maxillary palp. New diagnoses and illustrations are provided for R. minantenna and R. trichobasis, as well as a key to the known nymphs of Rivudiva species.

Two new species of Diplura C. L. Koch 1850 are described from Brazil: Dipluramapinguari sp. n., from the state of Rondônia in southeastern Amazonia, northern Brazil, and Diplurarodrigoi sp. n., known from southeastern and central west regions of Brazil. Diplurarodrigoi sp. n. is morphologically similar to D.lineata (Lucas, 1857), D.sanguinea (F. O. Pickard-Cambridge, 1896), and D.mapinguari sp. n. Comments on diagnostic characters of Diplura are included. The synonymy of D.maculata (Mello-Leitão, 1927) with D.catharinensis (Mello-Leitão, 1923) is corroborated. A classification of color pattern of the dorsum of the abdomen is given.

Of the 69 Neotropical species of Stylogaster, only one record was previously known from Northeastern Brazil (from Bahia state in 1985—S. brasilia Camras & Parrillo). Several specimens from this region housed at the MNRJ collection were studied, mostly from Bahia, Ceará and Pernambuco states. Two new records were obtained: S. macrura Lopes, 1938, previously known from São Paulo state (Southeastern Brazil), and S. souzai Monteiro, 1960, from Amapá and Pará (Northern Brazil). Descriptions of two new species, S. hugoi sp. nov. and  S. planitarsis sp. nov. are presented, as well as that of the previously unknown female of S. souzai. Illustrations and geographic distribution of the species are also provided.

A study of harpacticoid copepods from the intertidal zone of Jeju Island in the South Sea of Korea resulted in the discovery of two new paramesochrid species. They are placed in the genus Apodopsyllus Huys, 2009 on account of the following combination of characters: the absence of P2–P4 endopods, the poorly defined body segmentation, the two-segmented P1 endopod and exopod, and the fusion of the P2-P4 coxae with the respective body somites. Apodopsyllus gwakjiensis sp. nov. is most closely related to A. bermudensis (Coull & Hogue, 1978), but clearly distinguishable from it by the following characters: the concave shape of the baseoendopod with two bare setae, P4 basis without endopodal seta, and certain detailed characteristics of the mouthparts. Apodopsyllus unisetosus sp. nov. is easily distinguished from its congeners by the antennary exopod, which is armed with a single apical seta. In addition, A. unisetosus has the baseoendopod of P5 fused with somite, the P1 armed with one inner and one outer basal seta, and the unique shape of the male P6. Keys to genera of the family Paramesochridae Lang, 1944, as well as to species of the genus Apodopsyllus Huys, 2009 are provided.

We describe two new species of false spider mite in a new genus, Acaricis gen. nov., collected from native Australian sedges (Cyperaceae). The new genus shares morphological characters with the genera Tenuipalpus Donnadieu and Prolixus Beard, Fan & Walter. All three genera have dorsal opisthosomal seta h2 long and attenuate. Acaricis shares the presence of a rostral shield with Tenuipalpus; and shares with Prolixus an elongate body shape, absence of dorsal seta c1, genua I with two setae, nude genua IV, and setae g1 being inserted anterior to g2. Acaricis differs from both genera in having four palpal segments, as opposed to one to three.

Two new species of the genus Haliplus Latreille, 1802 are described and illustrated: H. fiorentini sp. n. and H. regili sp. n., from Roraima state in northern Brazil, bringing the number of species known from Brazil to 14. The new species can be distinguished based on a series of characteristics, mainly observed in the elytra, prosternal and metaventral process, legs and male genitalia.

Several specimens of monstrilloid copepods were collected in different localities of Brazil between 1993 and 1997. The taxonomic analysis of these specimens yielded the identification of two new species of Monstrilla. The first one, M. careli sp. nov. can be distinguished by a combination of several characters, including its body proportions, with a very long cephalothorax, by the particularly long terminal segment of the antennules, by the structure of its fifth legs, and by the very long dorsal seta on the caudal rami. The second species, M. brasiliensis sp. nov. can be distinguished by the peculiar features of its fifth leg, with a patch of long and stout hair-like setae along its outer margin; it has also a notched protuberance near the antennule bases. It has a notch on the anterior protuberance of the genital somite, and a ventrally swollen cephalothorax. This species, together with M. inserta Scott bears a pair of enigmatic structures which are either modified sensillae or a vestigial postantennular appendage not previously described in the Monstrilloida.

AbstractTwo new species of Sciadicleithrum Kritsky, Thatcher and Boeger, 1989 are described from two cichlids from the Araguarí River, State of Amapá, northern Brazil. Sciadicleithrum edgari n. sp. from Satanoperca jurupari (Heckel, 1840) differs from all congeneric species in the morphology (hook-shaped, with middle process and distally bifurcate) of the accessory piece of the male copulatory organ (MCO). Sciadiclethrum araguariensis n. sp. from Crenicichla labrina (Spix and Agassiz, 1831) can be distinguished from all other species by a Y-shaped accessory piece of MCO. In addition to the description of two new species, new host and geographical records of six dactylogyrid monogeneans from cichlid fishes are presented.
