Nomina Dubia

Maruina is an aquatic genus of Psychodidae with larvae and pupae adapted for life in flowing water. The genus is restricted to the Western Hemisphere, with the majority of species distributed in the Neotropical region. 39 Maruina species are described, with 11 currently known to occur in Brazil, all recorded from the eastern Biomes of Atlantic forest and Caatinga. Here we describe four new Maruina species collected from Brazil: Maruina (Aculcina) roraimensis sp. nov., Maruina (Maruina) kallyntrona sp. nov. and M. (M.) mystax sp. nov. constitute the first report of Maruina from Amazonia and M. (A.) pila sp. nov. from the southern portion of the Atlantic forest expands the distribution of the genus to Rio Grande do Sul, the southernmost state of Brazil. Type specimens of some described species were also studied. Redescriptions are completed for M. (M.) garota and M. (M.) namorada, and additional characters and figures are presented for M. (A.) duckhousei, M. (M.) barrettoi and M. (M.) jezeki. M. pilosella and M. spinosa are considered nomina dubia. Diagnostic characters for the genus and both subgenera are revised and distribution maps for Maruina species recorded in Brazil are provided.

Three New Species

New data about slender orb-weaving species of the cosmopolitan genus Tetragnatha are presented. Tetragnatha chauliodus (Thorell, 1890) and Tetragnatha tenuissima O. Pickard-Cambridge, 1889 are redescribed, including one synonymy for each species and the first record of the first species to the Neotropical region. Also, three new species are herein described, all based on males and females. Tetragnatha megalocera new species is recorded exclusively from Brazil (Espírito Santo, Rio de Janeiro, Rio Grande do Sul and São Paulo states), while Tetragnatha renatoi new species is recorded from Venezuela, Argentina (Misiones) and Brazil (Paraná, Pernambuco, Rio Grande do Sul, Rondônia, Santa Catarina and São Paulo states). Finally, Tetragnatha chiyokoae new species is described from Yunnan province (China) and Okinawa (Japan), with an additional record for Taiwan. Furthermore, Tetragnatha exilima (Mello-Leitão, 1943), Tetragnatha filigastra Mello-Leitão, 1943 and Tetragnatha lactescens (Mello-Leitão, 1947) are nomina dubia.

A New Species

Abstract: A new species of the genus Temnocephala Blanchard, 1849 from southern Brazil was found on two species of anomuran crustaceans, Aegla spinipalma Bond-Buckup & Buckup, 1994 and Aegla grisella Bond-Buckup & Buckup, 1994, the latter classified as a vulnerable species by the "Lista de Referência da Fauna Ameaçada de Extinção no Rio Grande do Sul. Decreto no 41.672, de 11 junho de 2002". The crustaceans were collected from a tributary creek of the Forqueta river, Perau de Janeiro, Arvorezinha and a tributary creek of the Fão river, Pouso Novo, Rio Grande do Sul, Brazil; both localities belong to the Sub-Basin of Forqueta River. The new species differs from seven other temnocephalans epibionts on Aegla Leach, 1820, by having the following characters: 1. a long and slightly curved cirrus, 2. two vaginal sphincters, one proximal, big and asymmetric, and one distal, smaller and symmetric, and; 3. longer than wide, elongated epidermal 'excretory' syncytial plates (EPs), with a almost horizontally central excretory pore, displaced to the anterior portion of the plate. The new species' EP is the largest in total length among epibionts temnocephalans in crustaceans already registered. Regarding the similarities with the male reproductive system of Temnocephala axenosMonticelli, 1898, the new species has important differences in the female reproductive system. It has a larger proximal vaginal sphincter, located in the middle of the vagina, while the smaller distal one is at the extreme end of the organ. Besides that, the vaginal portion between the proximal and distal sphincters is conspicuous, with a strong muscular wall. This is the first record of a species of Temnocephala in the Taquari Valley, as well in the 'Perau de Janeiro', which is an area with a rich endemic fauna.

The Family

The family Blaberidae contains large-sized species that may be apterous or subapterous with a rough pronotum, to fully winged with tegmina and wings extending beyond the apex of the abdomen. The family also contains small to medium-sized species colored green. Tribonium Saussure is placed in Zeborinae, one of the 10 subfamilies within Blaberidae (Roth 2003). Tribonium is essentially Neotropical, with species presenting a general brown coloration brown with dispersed black spots mainly on the tegmina. These similarities make species identifications difficult and further morphological studies of the genitalia are needed. Tribonium has a geographical distribution from French Guiana and Colombia to Brazil, Bolivia, Paraguay, and Argentina. The collection records are from tropical and subtropical forest, Atlantic forest, and regions of the Rio Grande do Sul. Currently, ten species are known, of which eight are Brazilian: T. conspersum (Guérin & Percheron), T. conspurcatum (Burmeister), T. delicatum Lopes, T. elegans (Brunner), T. gutulosum (Walker), T. litoris Lopes, T. neospectrum Lopes, and T. spectrum (Eschscholtz) (Lopes 1978).

New Distribution

Distictus aurantium new species, from the Brazilian Atlantic Forest, is described and illustrated. The validity of Distictus Townes was cladistically tested against 19 species and 60 informative characters, both with implied weighting and unweighted analyses. All cladograms recovered Distictus as monophyletic, while suggesting that it might be the sister group of the clade Lagarosoma Gupta + Prosthoporus Porter + Trypha Townes. Fenixia Aguiar is proposed as a new junior synonym of Distictus Townes, and the valid genus is transferred from Cryptina (=Ischnina) to Gabuniina. New distribution records expand the known range of D. tibialis to 17º48' latitude degrees, from Rio Grande do Sul to Goiás (Brazil).
