Distributional Knowledge

Diving beetles in the genus Platynectes (s. str.) in South America are relatively large and charismatically colored, yet relatively rare in museum collections. Recent fieldwork in northern and central South America has resulted in the collection of hundreds of new specimens that substantially expand our distributional knowledge of the genus. Here, we provide new distributional records for Platynectes decemnotatus (Aubé, 1838), P. garciai Gustafson, Short & Miller, 2016, P. submaculatus (Laporte, 1835), and P. tafelbergensis Gustafson, Short & Miller, 2016. In addition, two new species were identified and described herein: Platynectes bicolor sp. nov. of the P. ornatifrons species group from Brazil (Goiás and Mato Grosso do Sul), and P. colombicus sp. nov. of the P. submaculatus species group from the Guiana Shield region of eastern Colombia. These new records suggest that Platynectes (s. str.) is likely widespread across the Brazilian and Guiana Shield regions of the continent, and that some individual species have substantial range sizes of nearly 2000 km. An updated key to the species groups of Neotropical Platynectes (s. str.) and to the species of P. submaculatus species group are provided.

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.

Two New Species

Xiphocentron is the most species-rich genus of the pantropical family Xiphocentronidae. Among its five subgenera, Antillotrichia is the most diverse and the only one to occur in South America and Antilles. In the present study, two new species of Xiphocentron (Antillotrichia) are described from southern Atlantic Forest, Brazil. Xiphocentron gwarakeraba sp. nov. is diagnosed by the very elongate inferior appendage not bearing spines and with a simple mesal sclerite; X. muelleri sp. nov. is diagnosed by the inferior appendage with its ventral margin produced posterad and distinctly truncate. New distributional records are provided for X. acqualume, X. jaguare, X. kamakan, and X. maracanan. Additional non-genital diagnostic characters are presented for X. jaguare, and intraspecific morphological variations of forewing fork II (R3 and R4) and male genitalia are described for X. maracanan.

Anomaloglossus is a species-rich genus of frogs endemic to the Guiana Shield that still harbours several unnamed species. According to a recent integrative taxonomic survey, the A. stepheni species group includes five valid nominal species and at least four putatively unnamed species, two in Brazil and two in Suriname. In this paper, we describe the two species from Suriname based on adult and tadpole morphology as well as their calls and natural history. Both have exotrophic tadpoles transported by the male to small water bodies. These two new species differ from each other and from other congeners in body size, colouration pattern, call characteristics and breeding sites. Both have narrow distributions and should be considered Endangered according to IUCN criteria.

Two new species of the tribe Helopini (Coleoptera: Tenebrionidae) are described from Turkey: Nalassus (Nalassus) becvari sp. nov. (Elazığ Province) and Hedyphanes (Hedyphanes) kmenti sp. nov. (Artvin Province). The first species is characterized by strongly thickened antennomeres 2–8 and differs from all Turkish Nalassus s. str. Mulsant, 1854 in the ventral aspect of eye, which bears a weak posterior ventral impression (rather than a distinct groove of other species). The second species belongs to the species group with asperate punctation of the prothoracic hypomera and differs from all Hedyphanes Fischer von Waldheim, 1820 in the presence of suberect pubescence on both sides of elytral base. Distribution of some Helopini (the Helops genus-group, subtribe Helopina) from Anatolia and Cyprus is updated with new data. Hedyphanes mannerheimi Faldermann, 1837 is recorded for Turkey (Iğdır Province) for the first time. Helops caeruleus caeruleus Linnaeus, 1758 from Pervolia is a new record for Cyprus and the occurrence is probably a result of anthropogenic introduction.

Two New Species

Two new species are described in the Desmopachria convexa species group in the Neotropical genus Desmopachria Babington: D. mancosp. nov. (Guyana), and D. mortimersp. nov. (Costa Rica). Two subgroups, the D. convexa-convexa and the D. convexa-signata groups are defined. Desmopachria convexa-convexa species are from North and Central America and have a subapical articulable lobe on the male lateral lobe that is large and elongate and extends well beyond the slender, oblique apex of the lateral lobe. Desmopachria convexa-signata species are from South America and have a subapical articulable lobe on the male lateral lobe that is small and discrete and does not extend beyond the truncate apex of the lateral lobe. The male genitalia of all recognized species in the D. convexa group are redrawn from the literature. New species are illustrated from specimens and described species have morphological features redrawn from published illustrations.

Two new colourful species of direct-developing frogs of the genus Pristimantis are described from the summit of two isolated tepuis (sandstone table mountains) in the Eastern Pantepui District of the Guiana Shield highlands. Pristimantis jamescameroni sp. nov. is described from the summit of Aprada-tepui from 2557-2571 m elevation, and P. imthurni sp. nov. is described from the summit of Ptari-tepui at 2471 m elevation. Both species share the absence of a differentiated tympanic membrane and external tympanic annulus (but presence of tiny pharyngeal ostia), the presence of nuptial pads in males, and the presence of lateral fringes on fingers and toes, a combination of characters that immediately distinguishes them from all other known Pantepui congeners. The two new species are morphologically similar to each other and are phylogenetically closely related, but they can be distinguished based on colour pattern and morphological characters such as head proportions, dorsal skin texture, and condition of the supratympanic fold. The IUCN conservation status of the new species is considered as Endangered (EN) owing to their apparent very restricted ranges. The number of described Pristimantis species occurring exclusively on tepui (and faunistically related granitic mountains) summits and upper slopes now reaches eleven.

Two New Species

The oscinelline genus Medeventor Wheeler, 2007 was originally proposed for a single quite aberrant species from Central America, M. nubosus Wheeler, 2007. In this paper, we present two new Brazilian species of Medeventor—M. minimus sp. n. and M. tschirnhausi sp. n. (both from the State of Mato Grosso). A key for the species of the genus is provided. Some comments are made on the diagnosis of the genus.
