A New Species

A new species of Heteropterys belonging to the Parabanisteria informal group is described for the savannas grasslands of the Serra do Tombador Natural Reserve, municipality of Cavalcante, State of Goiás, Brazil. Heteropterys rosmarinifolia is easily distinguished from the remaining Brazilian species of the Parabanisteria informal group due to its stems unbranched, leaves associated with the inflorescence verticillate, blades linear to very narrowly oblong, strongly conduplicate, ascending to upright, and sparsely sericeous to glabrous at age. We present a complete morphological description for the new species, photographic plates, comments on its distribution, ecology, and taxonomy, besides an identification key to the species of Heteropterys from the Parabanisteria group from the State of Goiás, Brazil.

A new species of Pararhagadochir Davis, 1940 is described from the State of Tocantins, Brazil. Pararhagadochir castaneus sp. nov. differs from its congeners by relatively smaller size, elongated forewings, body uniformly chestnut-brown, submentum inflexed and strongly sclerotized, outer tip of 10Lp with both sclerotized and membranous areas and Cu vein unforked. An identification key to all species of Pararhagadochir and a short identification key to the Brazilian species are provided.

A New Species

Marantaceae is a family with approximately 550 species distributed throughout the tropics, with the exception of Australia (Andersson 2003). Calathea Meyer (1818: 6) used to be the largest genus in the family, previously including ca. 300 species. After the molecular study on the genus by Borchsenius et al. (2012), which confirmed the genus as polyphyletic, Goeppertia Nees (1831: 337) was resurrected to include all the species (approximately 245) that were not in the former subgenus Calathea Körnicke (1862: 112), the Calathea lanicaulis group (Kennedy et al. 1988) and the synonymized genus Sanblasia Andersson (1984: 21). Goeppertia thus became the most representative genus of Marantaceae, in Brazil represented by ca. 100 species (Braga 2013). It is found chiefly in rainforest habitats at elevations, below 1500m (Kennedy et al. 1988). However, the number of species may yet be underestimated due to unknown diversity of Brazilian species occurring in drier areas.

A New Species

A new amphipod species of the genus Elasmopus Costa, 1853 is described based on material collected from intertidal rocky shore, near the Suape Harbor, coast of the Brazilian state of Pernambuco. The new species may be recognized by the propodus of gnathopod 2 suboval, slightly tapering distally, palmar margin not defined by a stout seta, spine, or palmar corner, with a subdistal blunt tubercle, posterior margin covered by a dense fringe of plumose setae, and posterior margin of basis of pereopod 7 castelloserrate. This is the ninety-fifth species of the genus Elasmopus described worldwide, the most diverse genus in the family Maeridae Krapp-Schickel, 2008, and the eighth species recorded from Brazilian waters. An identification key to Brazilian species of Elasmopusis also provided.

A New Species

A new species of Hydrodynastes is described from the State of Tocantins, Central Brazil. The new species is distinguished from all congeners by having a melanistic color pattern, with head and dorsum of the body mostly dark-brown to black; absence of postocular stripe; venter grayish-brown, with dark rounded blotches outlining two lateral stripes which become gradually paler towards the posterior region of the belly, disappearing after midbody. Comparisons of the new species are made with others species of the genus and its affinity with H. gigas is suggested based on meristic and hemipenial characters

A new species of freshwater Amphipod, Gammarus topkarai sp. nov., collected from Ivriz Creek, Tarsus Province, South Anatolia, is described and illustrated. The new species belongs to Gammarus pulex-group and shows similar characteristic features with Gammarus agrarius G. S. Karaman, 1973. Absence of well developed dorsal elevations on the urosome segments, smaller body length and relatively lower endopod/exopod ratio of third uropod are the most obvious features differ from G. agrarius. A detailed morphological description and illustrations of new species are given and differences from related species are discussed. An updated identification key of Gammarus taxa reported from Turkey, up to date, was also presented.

A new species of the genus Dictyanthus is herein described and illustrated, more than 30 years since the last paper describing new species of this genus. Dictyanthus stevensii sp. nov. is known only from the Zoque forest in the Chimalapas region in the state of Oaxaca, Mexico. This species differs from all other species because it has the smallest flowers within the genus. It is morphologically related to D. eximius, a microendemic species of Chiapas. Information on the distribution and habitat of this new species is given, and its conservation status is proposed as Critically Endangered B2ab(ii). An identification key to Dictyanthus species in southern and southerneast Mexico is also provided.

The species of Centris of the hyptidis group are revised. The group, composed by C. hyptidis Ducke, C. hyptidoides Roig-Alsina, and C. thelyopsis n. sp., exhibits unique morphological characters within the genus, like foreand midtrochanters with a laminar expansion at the base, and elaiospathes strongly modified. An updated catalog, and floral and distributional records are provided for each species, as well as an identification key and a distribution map. The male of C. hyptidoides is described for the first time and a modern diagnosis for C. hyptidis is presented. A new species, C. thelyopsis n. sp., is described from Goiás State, in central Brazil. It can be easily distinguished from the two previously known species by its predominant orange pilosity, including that of the hind legs and metasoma.

We describe, illustrate and compare three new Brazilian species of Senegalia from the Atlantic Forest domain: Senegalia atlantica, from Rio de Janeiro State; Senegalia rafinesqueana, from the state of Paraná; and Senegalia cupuliformis, from Bahia State. These species are morphologically most similar to S. tenuifolia and S. multipinnata, S. velutina, and S. kuhlmannii, respectively. Additionally, we provide an identification key to all Senegalia species that are morphologically similar to S. atlantica, S. rafinesqueana and S. cupuliformis and occur in the Atlantic Forest domain; we also provide comments on the geographic distribution and the flowering and fruiting period of S. atlantica, S. rafinesqueana and S. cupuliformis.
