Phytoseiid mites have received considerable world wide attention because of their potential as natural enemies of phytophagous mites (McMurtry, 1984). The Amblyseius obtusus group Chant  is the largest species group in the genus Amblyseius. Chant & McMurtry (2004) divided the group into seven subgroups based on spermathecal morphology. The andersoni subgroup of Chant & McMurtry, 2004 is characterized by a spermatheca with the calyx dish-, cup-, bell-, or V-shaped, with the length/width ratio at the mid-point of the calyx < 3:1. A total of 24 species of the andersoni subgroup are known from the Neotropical region, 13 of these from Brazil (Moraes et al., 2004). A new species of this subgroup, Amblyseius paulofariensis sp. nov., is described and illustrated in this paper, from specimens collected in the semi-deciduous forest area of “Estação Ecológica de Paulo de Faria”, a protected natural area in the State of São Paulo, southeastern Brazil, on three species of Euphorbiaceae: Acalypha diversifolia Jacq., Actinostemon communis (Müll. Arg.) and Alchornea glandulosa Poepp. & Endl.. In the region where this mites was found, the climate is of the type Cwa-Aw of Köppen, with two distinct seasons: one wet, from October to March, and the other dry, from April to September. The annual mean temperature is 25°C, with a maximum mean of 30°C and a minimum mean of 20°C (Barcha & Arid, 1971; Arid & Barcha, 1973).

A new species of Leptodactylus belonging to the L. fuscus species group, and related to the L. mystaceus complex, is described from the Lagoa das Bromélias (20 o 53’S, 42 o 31’W; 1,227 m above sea level), Parque Estadual da Serra do Brigadeiro, Municipality of Ervália, State of Minas Gerais, Southeastern Brazil. Leptodactylus cupreus sp. nov. is characterized by the large size for the group (SVL 50.1–55.1 mm in males) and color pattern. The new species has a non-pulsed advertisement call, with call rate about 12 calls/s and a dominant frequency between 2,800 and 3,058 Hz.

A new sun-spider species of the ibirapemussu species-group of the genus Gaucha is described based on males and a female collected in Southeastern Brazil. The newly described species can be readily distinguished from its congeners by the reduction of the cheliceral fixed finger, distal tooth (FD), closely positioned and smaller than the medial tooth (FM); the presence of cheliceral fixed finger profondal subproximal (PFSP) and retrofondal submedial (RFSM) teeth; and by the cheliceral movable finger, medial tooth (MM) well developed, larger than submedial tooth (MSM) and smaller than proximal tooth (MP). This is the thirteenth described species in the genus Gaucha, all known from South America.

A new species was recently found in a cave from Southeastern Brazil, in the state of Minas Gerais, which is here described. Considering all the species of the genus, Spelaeogammarus uai sp. nov. is very similar to S. santanensis and S. sanctus, although the new species differs mainly in relation to the number of plumose setae in the apical margin of maxilliped inner plate, number of setae in the anterior margin of gnathopod 1 basis and number of setae in the posterior margin of gnathopod 2 basis. Furthermore, the ratio “length/width” of several articles of the new species is higher than in other species. An identification key of the Spelaeogammarus genus is provided, as well as a complemented multivariate statistical approach of the morphometry of the genus based on a previous work of the genus.

We describe a new species of hylid frog, Scinax peixotoi, from Queimada Grande Island, southeastern Brazil. The new species belongs to the Scinax perpusillus species group, in which all known forms inhabit bromeliads, and is diagnosed by the following set of characters: moderate-size (males 18.8–20.7 mm SVL, females 22.4–25.1 mm SVL); canthus rostralis distinct; dorsal skin slightly rugose; and a distinct advertisement call with relatively low dominant frequency. The new species is known from a single population on Queimada Grande, an island of 43 ha, approximately 33 km distant from the coast of São Paulo State, where it inhabits scattered patches of bromeliads. The highly specialized and patchy habitat of S. peixotoi, associated with its small range size, make this species highly susceptible to stochastic or anthropogenic habitat disturbances, which could lead it to extinction.

Several new records of the fairyfly genus Erythmelus Enock (Hymenoptera: Mymaridae) are reported from Argentina, Chile, and Guatemala, since the review by Triapitsyn et al. (2007). Erythmelus (Erythmelus) yuzhanin Triapitsyn sp. n., is described from Córdoba Province, Argentina. A key to the clavatus species group of the nominate subgenus is provided.

A new species of Pseudopaludicola is described from the Cerrado of southeastern Brazil. The new taxon is diagnosedfrom the P. pusilla species group by the absence of either T-shaped terminal phalanges or toe tips expanded, and promptlydistinguished from all (13) recognized taxa currently assigned to Pseudopaludicola by possessing isolated (instead of regular call series), long (117–187 ms) and non-pulsed advertisement calls.

A new species of the genus Helmutkunzia Wells & Rao, 1976 (Miraciidae) is described from specimens collected from an intertidal sandy beach in Xiamen, Fujian Province, China. Helmutkunzia xiamenensis sp. nov. differs from its two congeners by the length/width ratio of the female P5 exopod, the number or length of the setae on the sexually dimorphic P2 endopod in the male and the relative length of the spines on the endopodal lobe of the male P5. The Chinese species is morphologically closest to H. variabilis Wells & Rao, 1987 from the Andaman and Nicobar island chain. Females of both species can readily be differentiated by the relative length of the P5 exopod while males can be differentiated by the length of the armature elements on P2 enp-2 and the endopodal lobe of P5. The genus Balucopsylla Rao, 1972 is reviewed, resulting in the proposal of Pseudobalucopsylla gen. nov. to accommodate the type species Balucopsylla triarticulata Wells & Rao, 1987 and three new Indo-Pacific species previously identified with it: P. obscura sp. nov. from the Andaman Islands, P. costaricensis sp. nov. from the Pacific coast of Costa Rica and P. mielkei sp. nov. from the Galápagos archipelago. A key to species of Pseudobalucopsylla sp. nov. is provided.

A new species of Boholina, B. ganghwaensis sp. nov. is described, based on specimens collected from burrows of the manicure crab, Cleistostoma dilatatum, in the tidal flat of Ganghwa Island in western Korea. The new species is closely similar to B. purgata and B. parapurgata by having a pointed process on the posterior angles of the second and third pedigerous somites and a similar rostrum in the female, but can be distinguished from its congeners by the following characters: in females by the genital double-somite with small hook-like process on each gonoporal plate, the setation of the distal endopodal segment of mandible, the basis and first endopodal segment of the maxillule incompletely separated, the inner distal spine/outer terminal spine length ratio on P5; and in males by the distal spine present on the posterior surface of the basis of both P5 and the length/width ratio of the endopod of the right P5. This is the first Bololina species recorded from the north-west Pacific.
