A New Species

Petrocodon asterocalyx F.Wen, Y.G.Wei & R.L.Zhang, a new species from the Danxia landform area in Guangxi, South China, is described and illustrated based on molecular and morphological data. The molecular evidence shows that the new species is recovered in a weakly supported clade. Within this clade, the new one is morphologically similar to P. hancei (Hemsl.) A.Weber & Mich.Möller and P. coriaceifolius (Y.G.Wei) Y.G.Wei & Mich.Möller, and it can be distinguished from the former by calyx lobes 20–40 × 2–3 mm, corolla 2.5–3.0 cm long, filaments sparsely erectly pubescent, anthers sparsely pubescent, staminodes 3, and stigmas 2; from latter by leaf blades rhombic-oblong or rhombic, base shallowly cuneate, margin crenulate to serrate, calyx lobes linear, 20–40 × 2–3 cm, and anthers 3.5–3.8 mm long, sparsely pubescent and elliptical.

A New Species

The genus Minuartia is represented in Turkey by 34 taxa. Some interesting specimens were collected from Antalya province, and examined. These specimens resemble Minuartia meyeri, and M. multinervis from which differ by characters (macro-, and micromorphological) of inflorescence, alar pedicels, petals, sepals, capsules and seeds. Moreover, by using the DNA sequences of the ITS genes, phylogenetic relationships between this collected species, and the related species were investigated. As a result of the evaluation of molecular, and morphological data, we proposed to described the population from Antalya as a new species for the science. A description, pictures, distribution, habitat, and IUCN category are given.

A New Species

Abstract Aegla lata Bond-Buckup & Buckup, 1994 is considered extinct in the type locality. New populations of this species, however, have been found in northern Paraná state, Brazil. We revised the taxonomy of A. lata based on morphological data obtained from the type material and specimens recently obtained from streams of the Tibagi River sub-basin, Paranapanema River basin, Upper Paraná Ecoregion. Moreover, Aegla jacutingan. sp. is described and illustrated. The new species resembles A. lata in the shapes of the body and chelipeds. Both species are nevertheless separated by particular morphological characters of the carapace, chelipeds, and epimeron as well as by molecular (COI mtDNA) differences. Both species can be distinguished from their congeners based on morphological and molecular evidence.

A New Species

A new species of the portunid genus, Monomia Gistel, 1848, is described from the South China Sea in Vietnam. Monomia lucida sp. nov. is morphologically most similar to M. argentata (A. Milne-Edwards, 1861), which was originally described from Sarawak, on the island of Borneo. In addition to the stout, forward-directed anterolateral teeth of the carapace, the subrectangular sixth segment of the male pleon, and the long and slender laterally bent first gonopods, adults of the new species reach a greater size, and can also be distinguished from M. argentata by the colour pattern on the natatory dactylus. The independent specific status of M. lucida sp. nov. is also supported by molecular evidence. Aside from a comparison of this new species with other known congeners, new photographs of the holotype of M. samoensis (Ward, 1939) are also provided.

A New Species

Until now, Hargeria was considered a monospecific leptocheliid genus, with the species Hargeria rapax considered a taxon with a wide distribution, from the Northwestern Atlantic to the Mexican Caribbean. Herein, after a detailed revision of type and topotype materials and specimens collected from the Mexican Caribbean, a new species H. chetumalensis sp. nov. is described, and the redescription of H. rapax is provided. Also, we found a significant genetic divergence between the two species based on the nucleotide sequences of cytochrome oxidase subunit I, which support the morphological data. The morphological features used to recognize both species are also adequate to link males, females, and juvenile stages, although these species have a high intraspecific polymorphism.

Lespedeza danxiaensis (Fabaceae), a new species from Danxiashan National Nature Reserve in Guangdong Province, is described and illustrated. The new species is morphologically similar to Lespedeza pilosa, but it can be easily distinguished by its thin leathery leaflets and long peduncles. Phylogenetic analysis based on ITS confirmed that the new species belongs to Lespedeza subg. Macrolespedeza. The new species is the first known species of Lespedeza endemic to Danxia landform and is currently only known from Mount Danxia, Guangdong.

A New Species

A new species group, the riverata species group, is established within the genus Scaptodrosophila based on morphological and molecular evidence for five known and five new species from China: S. abdentatasp. nov., S. cederholmi (Okada, 1988), S. crocata (Bock, 1976), S. paraclubata (Sundaran & Gupta, 1991), S. platyrhinasp. nov., S. puncticeps (Okada, 1956), S. riverata (Singh & Gupta, 1977), S. serrateifoliaceasp. nov., S. sinuatasp. nov. and S. tanyrhinasp. nov. A key to this group is provided. Furthermore, 51 mtDNA COI sequences belonging to S. puncticeps, S. riverata and the five new species are used for verifying species boundaries defined by the morphological data.

A New Species

The gregarious species of Apanteles that attack cactus-feeding phycitine moths (Lepidoptera : Pyralidae) from Argentina are identified using DNA barcodes and morphological data. Sequences of specimens from 10 different populations were generated. Corrected genetic divergences showed two clusters of specimens separated by COI divergences higher than 6%. Our morphological examinations were congruent with the molecular evidence and therefore two species were confidently identified: Apanteles alexanderi Brèthes and a new species, Apanteles opuntiarum Martínez & Berta, sp. nov., which we describe and illustrate. Despite these two taxa being considered to represent a single polyphagous species for at least 50 years, they can be easily distinguished by the length of their ovipositor sheaths. A key to the species of microgastrine parasitoids of cactus-feeding Lepidoptera in South America is provided. The recognition of the new species reveals a narrower host range for the species involved in this system, making it necessary to re-evaluate their potential as biocontrol agents of the prickly pear moth.
