Four new species in the caddisfly genus Contulma Flint 1969 (Trichoptera: Anomalopsychidae) are described from Bolivia and southeastern Brazil: C. boliviensis n. sp. (Bolivia), C. fluminensis n. sp. (Brazil), C. meloi n. sp. (Brazil), and C. tripui n. sp. (Brazil). The Bolivian species represents the first record of the genus and family for Bolivia. The Brazilian species form a closely related group of species also including C. tijuca Holzenthal & Flint 1995.

A new species of the genus Charinus—C. vulgaris— is described from Porto Velho, Rondônia. This is the first record of the family Charinidae from the Brazilian Amazonia and of a synanthropic species in South America. Additionally, two new records of the genus for Brazil are made and a key to the Brazilian species of the genus is given.

A new species of Kunzeana Oman, 1949 (Hemiptera: Cicadellidae: Typhlocybinae), Kunzeana zantedeschia sp. nov. is described and illustrated based on specimens from Minas Gerais, southeastern Brazil. The new species differs from its congeners by a membranous sheath surrounding the aedeagal stem and a pair of short dorsal processes at aedeagus base.

A New Species

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

A new species of the freshwater amphipod Hyalella Smith, 1874 is described for the plateau of the Itatiaia National Park, located between the states of Minas Gerais and Rio de Janeiro, southeastern Brazil. This is the first Brazilian species of Hyalella found at more than 2,200 meters of altitude. The specimens were found in a small stream, buried under rocks, in the higher area of the Park. The main morphological characteristics that differentiate the new species are the extreme reduction of the size of the uropod 3, absence of apical setae on telson, absence of comb-scales on gnatopods 1 and 2, absence of curved seta on inner ramus of uropod 1 and sternal gills tubular on pereonites 3 to 7. The new species presents similarities with some cave species of the genus, apparently being troglophile and that is the process of adaptation to the hypogean habitat. The importance of creating new protected areas for the conservation of Hyalella in Brazil is discussed.

A New Species

Deltamys is a monotypic sigmodontine rodent from the Pampas of South America. In addition to the formally recognized D. kempi that inhabits lowlands, an undescribed form Deltamys sp. 2n=40 was recently found in the highlands of southeastern Brazil. In the present study, we perform a phylogeographic reassessment of Deltamys and describe a third form of the genus, endemic to the Brazilian Araucaria Forest. We describe this new species based on an integrative analysis, using complete cytochrome b DNA sequences, karyology and morphology. Bayesian tree recovered two allopatric clades (lowlands vs. highlands) and three lineages: (i) the lowland D. kempi, (ii) the highland Deltamys sp. 2n=40, and (iii) Deltamys araucaria sp. n. Deltamys araucaria sp. n. is karyotypically (2n=34) and morphologically distinguishable from D. kempi (2n=37-38), showing a tawnier dorsum/flank pelage, presence of a protostyle, M1 alveolus positioned anteriorly to the posterior margin of the zygomatic plate, and several other distinguishing characteristics. A phylogeographic assessment of D. kempi recovered two haplogroups with significant differences in skull measurements. This phylogeographic break seems to have been shaped by the Patos Lagoon estuarine channel. The diversification in Deltamys might have been triggered by dispersal of older lineages over different altitudinal ranges in the Paraná geological basin.

New Diagnosis

Hoplonannus McAtee & Maloch, 1925 comprises three species described from Central America. Females of all these species are known only from brachypterous specimens. This paper describes the first South American species of the genus, Hoplonannus australis sp. nov. The new species differs from its congeners, in females, by the submacroptery, presence of ocelli and a basal bulge in the seventh sternite; in males, it differs by the presence of a process in the eighth tergite and the right paramere bifurcate apically, with branches subparallel. These traits entail a new diagnosis for the genus.

The tribe Diglottini Eichelbaum, 1909 comprises two halophilous rove beetle genera Diglotta Champion, 1899, and Paradiglotta Ashe & Ahn, 2004. The tribe contains eight known species distributed in the Nearctic and West-Palaearctic regions, and also Fiji Islands and New Zealand. This tribe is recorded for the first time from South America with the description of a new species, Diglotta brasiliensis n. sp. from southern Brazil (Paraná). Characters of the mouthparts, aedeagus and spermatheca of the new species are illustrated and compared with other Diglotta species. Sexual dimorphism is reported for the first time in the genus.

We describe seven new Neotropical species of Tischeriidae: Astrotischeria dondavisi Stonis & Diškus, sp. nov., A. bacchariphaga Diškus & Stonis, sp. nov., A. guatemalica Diškus & Stonis, sp. nov., A. sanjosei Stonis & Diškus, sp. nov., A. truncata Diškus & Stonis, sp. nov., Coptotriche parvisacculata Diškus & Stonis, sp. nov. and C. carmencita Stonis & Diškus, sp. nov. We report the discovery of Coptotriche Walsingham in South America and provide the following new host-plant records for the Neotropical Tischeriidae: Terminalia australis Cambess. (Combretaceae), Baccharis latifolia (Ruiz & Pav.) Pers., and B. emarginata (Ruiz & Pav.) Pers. (Asteraceae). We update the biology of Astrotischeria ochrimaculosa Diškus, Stonis & Vargas with the discovery that Wissadula (Malvaceae) is a new, verified host plant. The new species are illustrated with photographs of the adults, male and, if available, female genitalia, and the leaf mines. We expect broader distributions of tisheriid species in South America inferred from known host-plant distributions.
