Two New Species

ABSTRACT Members of the Leporinus desmotes species complex can be distinguished from other barred or banded congeners by the combination of nine distinct black bars across the head and trunk and long, pointed, laterally compressed and upward curving symphyseal dentary teeth. A taxonomic reassessment of this complex revealed two new species, one from the Orinoco and Negro rivers of Venezuela and Brazil, and the other from the Xingu and Tapajós rivers of Brazil. Both species are similar to L. desmotes and L. jatuncochi, but differ significantly in body shape morphology, coloration, and/or circumpeduncular scale counts. Genetic evidence also contributes to the recognition of both new species. This contribution also maps the geographic distribution of the four known species, and highlights the presence of an unusual meristic polymorphism within Leporinus desmotes sensu stricto that may suggest the presence of even more unrecognized diversity.

We provided a new diagnosis of the genus Stigmaeopsis. Then we described two new species that are very closely related to Stigmaeopsis miscanthi (Saito) from Miscanthus spp. in Japan and China. The Japanese species, named Stigmaeopsis sabelisi Saito and Sato n. sp., was previously referred to as Stigmaeopsis miscanthi low aggressiveness form , and is characterized by its low male-to-male aggression behavior. The other species, Stigmaeopsis continentalis Saito and Lin n. sp., was found in China (Fujian district). Thus four species could be discriminated from the species inhabiting Miscanthus and reed grasses. However, the two new species and S. miscanthi resemble each other very closely, thus they are considered to be sibling species. To identify them several naive characters, geographic distribution and genetic data are needed. An updated key to all known species of Stigmaeopsis is also proposed.

Two New Species

The genus Triaenogryllacris is redescribed and a key for identification of the species is provided. When dealing with observations of iNaturalist, accurate data about the distribution of T. triaena (the type species) are obtained, and three color forms are indicated: yellow, pink and green. Two new species are described here: T. diaena n. sp. and T. horaciotrianai n. sp., expanding the expected geographic distribution for the genus, thus recorded, from the Andean forests of Ecuador and Colombia’s three mountain ranges. Finally, the characters and distribution of Triaenogryllacris are discussed, contrasting with the other taxa described for the family Gryllacrididae.

The aim of this study is to conduct a detailed taxonomic revision of the Poecilimon (Poecilimon) zonatus species-group (Orthoptera: Phaneropterinae) using both morphology and bioacoustics. Two new species (Poecilimon (Poecilimon) salmani, P. (P) azizsancar) and one new subspecies (P. (P) zonatus datca) are described. Based on the data, we conclude that the species complex can be separated into two subgroups (P. tauricola and P. zonatus). Within the P. zonatus subgroup, song structures indicate P. variicercis as basal branch since producing two syllable types is possibly a derived character. From both, from bioacoustics and morphology, it is concluded that the relationships between species of the group are as follows: P. tauricola subgroup (P. tauricola + P. azizsancar) + P. zonatus subgroup (P. variicercis + (P. varicornis + (P. zonatus zonatus+P. zonatus datca)) + (P. salmani+P. vodnensis)))). Except for two species (P. vodnensis and P. varicornis), the other species of the group are all distributed in Anatolia. P. vodnensis is known only from Macedonia, whereas, P. varicornis has been recorded only from Syria and Lebanon. We assume that the group originated from an Anatolian ancestral stock and expanded its distribution to the Balkans through Taurus Way and Dardanelles. Other ancestral populations may have also spread in the north-south directions through the appropriate steppe corridors in the Anatolian Diagonal Mountains and in its vicinity.

Two New Species

Two new species of the nudibranch genus Okenia Menke, 1830 (Goniodorididae) are described, one from eastern Australian waters and one from the western Indian Ocean. Okenia atkinsonorum sp. nov. is the third Australian species reported to feed on the bryozoan Pleurotoichus clathratus (Harmer, 1902) and is very similar in external shape and colour to the other two species, O. hallucigenia Rudman, 2004 and O. stellata Rudman, 2004. Okenia rhinorma sp. nov. is reported from Tanzania and the Red Sea. Its body shape and anatomy suggest it is related to the ascidian-feeding group in the genus characterised by O. aspersa (Alder & Hancock, 1845).

Three coelomycete species with muriform conidia were collected in Italy and subjected to morpho-molecular analyses. In morphology, all species are similar to Camarosporium sensu stricto. Based on morphology, one was identified as C. spartii and the other two taxa are introduced as new species, viz. C. clematidis and C. robiniicola. Maximum likelihood, maximum parsimony and Bayesian analyses of the combined LSU, SSU and ITS dataset show that the three taxa cluster with C. quaternatum, the type species of Camarosporium, with high bootstrap and PP values. All four species can be considered as Camarosporium sensu stricto. Cucurbitaria elongata groups in the Camarosporium clade near to Camarosporium robiniicola and is considered that it is not congeneric with Cucurbitaria sensu stricto (Cucurbitariaceae).

Two new species of Chelodesmidae from the Brazilian northeast are described, Iguazus robustussp. nov., from the state of Paraíba, and Tessarithys exacuminatussp. nov., from the states of Pernambuco and Sergipe. Iguazus robustussp. nov. differs from other species of the genus by having a constriction in the zone of the gonopodal acropodite tip and an extra branch at the tip of the acropodite. Tessarithys exacuminatussp. nov. differs from the other species of the genus by the large and ascending subterminal dorsal branch of the prefemoral process of the gonopod. Brief reviews of the taxonomy, geographic distribution and a key for males of the respective genera are provided.

Two new species of Terebrasabella Fitzhugh & Rouse, 1999 are described from eastern Australia. Terebrasabella hutchingsae sp. nov., was found from preserved coral rock debris collected in 1977 on the outer Barrier Reef near Lizard Island, Queensland. Terebrasabella fitzhughi sp. nov., was found alive in burrows in and among spirorbin serpulid tubes on intertidal rocks in Tasmania in 1996. Both species were found in mucoid tubes, and brood their young in a manner similar to the only other described species of Terebrasabella, T. heterouncinata Fitzhugh & Rouse, 1999. Terebrasabella hutchingsae sp. nov., is exceptional as it possesses a type of thoracic neurochaetal uncinus different from the other two species, and which is similar to the notochaetal acicular “palmate hook” seen in Caobangia. Descriptions of both species are given, and the diagnosis for Terebrasabella is emended. Larval and chaetal morphology and relationships among of the three known Terebrasabella spp. are discussed.

AbstractThe systematics of Acalymma sensu stricto of North America including Mexico are revised. Acalymma sensu stricto is defined and distinguished from the other species groups of Acalymma. Sixteen species are discussed including four new species: A. blomorum, A. palomarense, A. invenustum, and A. luridifrons all from Mexico. Three new subspecies of A. blandulum (LeConte) are described: blandulum (LeConte) new status, nigriventre, and yucatanense. Acalymma coruscum costaricense Bechyné is placed as a synonym of A. innubum (Fabricius). Keys are presented to all species and subspecies. Habitus and male genitalia drawings are given for all species and distribution maps are given where appropriate.
