A New Species

The Lepidocyrtus lanuginosus group is formed by the species L. lanuginosus and L. cyaneus, which can be differentiated by the body color pattern. In the present paper several populations of these two species from the Northeastern Iberian Peninsula have been studied. This study has allowed the detection of chaetotaxic and morphological differences distinguishing the two mentioned species. Also the description of the new species L. bicoloris has been made (also characterized by the body color pattern), as well as a redefinition of the European Lepidocyrtus lanuginosus group.

Apogonichthyoides is resurrected from Apogon (Ostorhinchus) as a valid genus with 19 species. Members of this genus are mostly tannish brown to brownish-black in body color. The head and body usually have brownish to blackish spots (sometimes stripe-like), a darkish cheek line and usually two body bars. An ocellus may be present below the lateral line on the body or absent. One or more caudal-peduncular bars and/or a basicaudal spot are often present. Insertion patterns of supraneurals and pterygiophores are given for 11 species. Apogonichthyoides umbratilis, a new species, has 14 pectoral rays and five bars (three faint) on the body and caudal peduncle. Color pattern of the new species suggest relationships with Apogonichthyoides gardineri, A. timorensis and A. opercularis. Descriptions and illustrations of the latter two species are provided for comparison. Apogonichthyoides gardineri, a rare, deep-water species is characterized by 14 pectoral rays, two bars on the body and one wide bar near the base of the caudal peduncle. Specimens of Apogonichthyoides timorensis usually have 15–16 pectoral rays and two or three bars on the body and caudal peduncle. Specimens of Apogonichthyoides opercularis have nine soft anal rays and 10 soft dorsal rays. A key to eight species included in the timorensis species group is provided. A lectotype and paralectotypes are designated for the syntype series of Apogon opercularis. New name combinations follow: Apogonichthyoides atripes, A. brevicaudatus, A. cantoris, A. chrysurus, A. euspilotus, A. gardineri, A. heptastygma, A. niger, A. opercularis, A. pharaonis, A. pseudotaeniatus, A. regani, A. sialis and A. timorensis. Previous usage includes: Apogonichthyoides enigmaticus, A. nigripinnis, A. taeniatus and A. uninotatus

A New Species

ABSTRACT A new species of Ituglanis associated to the grasslands of the Pampa biome is described from the rio Uruguai basin, southern Brazil. The new species is distinguished from its congeners by the low number of ribs and by a unique color pattern composed of an outer layer with scattered round black blotches equivalent in size to the eye circumference over a reddish brown background on the lateral surface of the body. We provide the genetic sequences of the mitochondrial gene Cytochrome c Oxydase subunit I (COI) for three of the paratypes and discuss aspects about the recent discovery of the new species.

A New Species

A new species of Leporinus Agassiz is described from the rio Curuá, a tributary of the rio Iriri, rio Xingu basin, Serra do Cachimbo, Pará State, Brazil. The new species is diagnosed by the color pattern, which consists of eight to ten midlateral round dark blotches plus 20 to 40 smaller ones scattered over the body, dental formula 3/4, subinferior to inferior mouth, 37 to 38 lateral line scales, 4/3-4 transversal series of scales, and 12 circumpeduncular scale series. The new species most closely resembles L. octomaculatus and L. reticulatus from the upper Tapajós basin, and L. marcgravii and L. microphthalmus from the rio São Francisco and the rio Paranaíba, respectively. Based on recently collected specimens, L. reticulatus is re-diagnosed as having an allometric elongation of the snout.

A New Species

A new species of the romaleid grasshopper genus Zoniopoda Stål (Romaleidae: Romaleini) is described and illustrated from the Sierras Chicas of Córdoba Province, central Argentina. A cladistic analysis based on morphological characters indicates that the genus Zoniopoda constitutes a monophyletic group and that Zoniopoda serrana n. sp. must be assigned to Iheringi species group based on synapomorphies of the pronotum and body color. The new species is similar to Z. similis Bruner from Paraguay, Bolivia and Brazil, from which it can be distinguished by the color pattern of the body, shape of the pronotal dorso-median carina and characters of the male terminalia and epiphallus. This paper has been formatted with embedded links to images of the type specimen, maps based on georeferenced specimen data for the genus and an updated key to the species of Zoniopoda available on the Orthoptera Species File (OSF) online (http://orthoptera.speciesfile.org).

A New Species

We describe a new species of montane pitviper of the genus Bothrops from the Cordillera Oriental of the Central Andes, distributed from southern Peru to central Bolivia. The new species can be distinguished from its congeners by the characteristic combination of a dorsal body color pattern consisting of triangular or subtriangular dark brown dorsal blotches, paired dark brown parallel occipital stripes, a conspicuous dark brown postocular stripe, the presence of canthorostrals in some specimens, prelacunal fused or partially fused with second supralabial, one scale usually separating internasals, rostral trapezoidal, two canthals oval to rounded, similar size or slightly larger than internasals, three or four medial intercanthals, eight to twelve intersupraoculars, intercanthals and intersupraoculars keeled and frequently slightly keeled, supraoculars oval, one to three suboculars, two to three postoculars, loreal subtriangular, two to six prefoveals, subfoveals absent, two or none postfoveals, one or two scales between suboculars and fourth supralabial, seven or eight supralabials, nine or eleven infralabials, 23–25 middorsal scales, 189–195 ventrals in females and 182–190 in males, 48–58 subcaudals in females and 54–63 in males, exceptionally undivided. The new species is apparently restricted to areas within Andean montane forests that are less humid and devoid of large trees.

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

Lepidocyrtus lusitanicus is one of the species with greater color pattern variability within the genus Lepidocyrtus. Four subspecies have been described in relation to its body color variation. The study of various populations of Lepidocyrtus from the Iberian Peninsula has allowed me to describe the new chromatic form L. lusitanicus form A, as well as the new species L. bilobatus, which is very closely related to L. lusitanicus, and also shows high color pattern variability. The high similarity among species L. lusitanicus, L. selvaticus and L. bilobatus sp. nov., the high color pattern variability of their populations, the overlapping geographical distribution of many studied populations, and the presence of three dorsal macrochaetae between trichobothria m2 and a5 of the second abdominal tergum, led me to define the group Lepidocyrtus lusitanicus species-complex. This group included the three abovementioned species with all of their color forms.

A New Species

Characidium xanthopterum is described from tributaries of the upper rio Paraná and upper rio Tocantins basins, in the Central Brazilian Plateau, Goiás State, Brazil. The new species is diagnosed among congeners by the absence of dark bars on the sides of the body in adult specimens, and by the deep yellow coloration in all fins. Ontogenetic change of color pattern is recorded for the first time for Characidium species. Specimens smaller than 32 mm SL possess dark bars on body. These bars disappear with growth between 32 and 35 mm SL, and are always absent in individuals larger than 35 mm SL.
