A New Species

A new species of Stygnidae is described from the state of Bahia, Brazil. Protimesius bahiensis sp. nov. can be distinguished from the remaining species of the genus by the combination of: male femur IV unarmed and cylindrical; male patella IV with a row of large dorsal acute tubercles, increasing in size distally and male tibia IV with one mesodistal tubercle; ventral plate of the penis with three pairs of distal curved setae and one pair of intermediate setae, smaller than the rest. A cladistic analysis of the subfamily is presented. Stygninae is divided in two groups of genera: (Ricstygnus, Stygnus, Sickesia), with a wide distribution and (Pickeliana (Protimesius (Phareus (Stenophareus (Auranus (Verrucastygnus, Stenostygnoides)))))), associated to the Guiana Shield, Amazon basin and Northeastern Brazil. The monophyly of Protimesius is supported by the apex of pedipalpal tibia sockets bifid (homoplastically present in Verrucastygnus and Stenostygnoides) and by the presence of scopulae with non-spatulated hairs.

A New Species

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

A New Species

A new species of Dendrophidion belonging to the D. dendrophis species group is described from Mata do Engenho Coimbra (08°59’S, 35°53’W; 526 m above sea level), Municipality of Ibateguara, in the Atlantic Rainforest remnants of the State of Alagoas, northeastern Brazil. Dendrophidion atlantica sp. nov. is characterized by having 154–163 ventral scales, 140–160 subcaudal scales, tail length 62.2–74.8% of snout–vent length, collar absent, head uniformly brown and dorsal ground color brown, paler on anterior third, with cream transversal lines (one half a scale long), bordered anteriorly and posteriorly by dark brown lines (one half a scale long), distributed from the neck to the tail; hemipenis single, subcylindrical, unicapitate, and unicalyculate; calyces large, well defined, papillate; a series of 12 large spines just below the capitulum, on the asulcate and lateral sides; a series of four spines, two large laterals and two small between them, in the basal region of the asulcate side of the organ body; two large spines on the lateral distal areas of the sulcate side of the hemipenial body; sulcus spermaticus centrolineal, bifurcating at the tip of the capitulum.

A New Species

A cladistic analysis of the genus Atlantodesmus Hoffman, 2000 is presented. With a total of 11 taxa and 30 morphological characters, and under implied weighting (k = 3), two equally most parsimonious trees (length = 58 steps; total fit = 23.150; CI = 0.64; RI = 0.64) recovered the monophyly of the genus. The resulting synapomorphies are: absence of a ventral projection on the post-gonopodal sternites; presence of folds on the dorsal edge of the prefemoral region of the gonopod; and one homoplastic transformation: presence of a cingulum. In addition, Atlantodesmus sierwaldae sp. nov. is described from the state of Minas Gerais, in the Brazilian Cerrado, and a key to the males of the genus is provided.

We describe a new species of Oxyepoecus Santschi, 1926, Oxyepoecus regularis sp. nov., based on workers and a gyne collected in "Caatinga Arbórea" (Arboreal Shrubland) in Milagres and "Mata Seca" (Dry Forest) in Boa Vista do Tupim, both in the state of Bahia, Brazil. The gyne of Oxyepoecus browni Albuquerque & Brandão, 2004, collected in the same leaf litter ant survey, is also described. In addition, we present new records for Oxyepoecus species in Northeastern Brazil.

A new species of Tropidurus of the semitaeniatus group is described from northeastern Brazil. Tropidurus sp. nov. is morphologically similar to other species of the group in the marked dorsoventral flattening of the body, and the presence of a series of sublabial shields that are larger than the adjacent scales. It is distinguished by a single middorsal longitudinal light stripe that extends from the snout to the scapular region. The new species appears to have the largest body size of the group. The new species inhabits the Vale do Jaguaribe, in the eastern part of the state of Ceará, where there are many fissured rocky outcrops surrounded by hypoxerophytic caatinga vegetation.

Zanthoxylum unifoliolatum Groppo & Pirani (Rutaceae), a new species from northeastern Brazil is here described and illustrated. To date, this species is known from a small number of collections from the state of Sergipe and considered endangered, given its restricted geographical distribution and the rapid deforestation of the Brazilian Atlantic Rainforest. Z. unifoliolatum can be readily distinguished from other Brazilian Zanthoxylum by its unifoliolate leaves, rather than pinnate leaves present in other Brazilian species of the genus A detailed description and illustrations of this new species are provided, as well as comments on the geographic distribution, phenology, generic relationships and conservation status. Additionally, a key to the species of Zanthoxylum from Northeastern Region of Brazil is provided.
