A New Species

Plants belonging to the genus Petrocosmea are rare and small herbs difficult to find in the wild. In the present study, a new species, Petrocosmea duyunensis, from Guizhou, China, is described. The species is most similar to P. leiandra and differs from it by a distinctly recurved abaxial corolla lip, free anthers and included pistil. Detailed morphological comparisons are given. One population with about 100 mature individuals was found at the type locality. This new taxon was assessed as “Data Deficient” (DD) according to the IUCN standards.

Argostemma separatum, a new species with free stamens in star-shaped corolla from Mt. Halcon Oriental Mindoro, Philippines is here described and compared with Argostemma diversifolium, the only species of the genus with this type of flower. This species is distinct from A. diversifolium by its indumentum on stem, leaf blades and calyx, smaller leaf blades, fewer flowered inflorescences, shape of stipule and calyx, red tips on corolla lobes, and color of anthers. Based on the recent IUCN categories, the conservation status of A. separatum is Data Deficient (DD) since it was only collected at the type locality.

We describe a new species of salamander of Bolitoglossa (Oaxakia) Parra-Olea, García-París and Wake, 2004 from the cloud forests of the central portion of the Sierra Madre del Sur highlands in the Mexican state of Guerrero. Bolitoglossa coaxtlahuacana sp. nov. is currently known only from the type locality and can be differentiated from other members of the group by morphological, coloration, and molecular evidence. With the description of this new taxon, the number of species in the subgenus Oaxakia increases to six.

A New Species

The genus Pygidiapion De Sousa & Mermudes gen. n., described and illustrated here, includes two species from Brazil: the type-species Pygidiapion zeppelinii De Sousa & Mermudes sp. n. (type-locality: João Pessoa, Paraiba state), which develops in flower buds of Pterocarpus violaceus Vogel (Fabaceae); and Pygidiapion zikani (Heller, 1922) comb. n. (from Apion) (type-locality: Passa Quatro, Minas Gerais state), which develops in flower buds of Dalbergia foliolosa Benth. (Fabaceae). Pygidiapion is defined by the following set of characters: rostrum of males with two elongate longitudinal and punctate latero-ventral sulci; hind wings with small radial window; hypomeral lobes divided by median suture and sternellum distinctly exposed; meso- and metatibiae mucronate; pygidium of the apionine incomplete type; and tegminal plate fused with basal piece. Pygidiapion zeppelinii is diagnosed by: meso- and metatibiae mucronate; pygidium distinctly modified, with deep transverse dorsal sulcus, medially deeper and rounded, and proximal marginal rim angulate (apical flange), corresponding to the distal margin, which is emarginate; tegminal plate fused to basal piece, apical portion of parameroid lobes weakly notched medially, each side of suprafenestral plate with five macrochaetae, fenestral width 1.25 times length, separated by about 3.2 times fenestral width, linea arquata visible, prostegium protruding medially, tegminal apodeme 0.76 as long as basal piece, with apex narrow and rounded. Pygidiapion zikani is distinguished from P. zeppelinii by smaller size; head, rostrum and antennae brownish; scutellum subquadrate; and by association with Dalbergia spp. (Fabaceae). Association principally with the papilionoid group of Fabaceae suggest allocation of the new taxon to the subtribe Oxystomatina.

Insight Into

Abstract The late Paleozoic temnospondyl Sclerocephalus formed an aquatic top predator in various central European lakes of the late Carboniferous and early Permian. Despite hundreds of specimens spanning a wide range of sizes, knowledge of the endocranium (braincase and palatoquadrate) remained very insufficient in Sclerocephalus and other stereospondylomorphs because even large skulls had unossified endocrania. A new specimen from a stratigraphically ancient deposit at St. Wendel in southwestern Germany is recognized as representing a new taxon, S. concordiae new species, and reveals a completely ossified endocranium. The sphenethmoid was completely ossified from the basisphenoid to the anterior ethmoid region, co-ossified with the parasphenoid, and the basipterygoid joint was fully established. The pterygoid bears a slender, S-shaped epipterygoid, which formed a robust pillar lateral to the braincase. The massive stapes was firmly sutured to the parasphenoid. In the temnospondyl endocranium, character evolution involved various changes in the epipterygoid region, which evolved distinct morphologies in each of the major clades.

Basal Structure

Abstract. A very distinctive new deep-photic coccolithophore is described from the NE Indian Ocean. The new species is trimorphic with: 200–300 body coccoliths bearing low spines attached by narrow stems to a basal narrow-rimmed placolith structure; up to 18 circum-flagellar coccoliths with tall sail-like spines; and up to 22 coccoliths with moderately elevated spines occurring both around the circum-flagellar coccoliths and antapically. These features make the coccolithophore unique and require placement in a new species and genus. The basal structure, however, shows similarities to a recently recognized group of narrow-rimmed placoliths. Hence, the new coccolithophore provides some support for this grouping as a significant addition to our understanding of coccolithophore biodiversity, and potentially an explanation for a set of anomalous molecular genetic results. In addition the new taxon provides further evidence that the deep-photic coccolithophore community is more diverse than has been assumed.

Freshwater Diatom

During a survey of the freshwater diatom flora of the sub-Antarctic region (Iles Kerguelen and Iles Crozet) in the southern Indian Ocean, an unknown Cyclotella taxon was observed that was formerly identified as the presumed cosmopolitan C. meneghinana. Detailed morphological analysis based on light and scanning electron microscopical observations and comparison with several similar Cyclotella taxa worldwide justified the description of this unknown taxon as a new species: Cyclotella deceusteriana sp. nov. The new taxon is characterized by the presence of marginal fultoportulae on every costa, hyaline furrows between the raised marginal parts on which the striae are located, 2, occasionally 1, 3 or 4 central fultoportulae and an entirely flat, smooth, relatively small central area. The new species is described and compared with other Cyclotella taxa. Notes on its distribution and ecology are added.

A New Species

We present the description of Phrynus calypso sp. nov. from Trinidad and Tobago, and Venezuela This species is very similar to Phrynus pulchripes (Pocock), however after examining Colombian specimens of P. pulchripes (ca. type locality), many differences were found. Characters commonly used in diagnosis of Phrynus species are variable and make identification difficult. Differences in a few structures, like pedipalpal spines, could not be enough to provide a useful diagnosis.  It is necessary to account for variation of similar species in conjunction, and select non overlapping groups of characters. Observations in the variation in both species are presented, pointing out sources of confusion, and suggesting alternative characters to support diagnoses. At the moment, details about variation in many species in Phrynus, like that of P. pulchripes, are poorly known, and for this reason a redescription is provided.

A New Species

In May 2020, a new taxon of Euphorbia, Euphorbiaceae was collected from a dry hillside of Dongsheng District, Ordos City, Inner Mongolia. The morphological characteristics of the specimens analyzed differ from those of the known Euphorbia species from this region; therefore, we suspected this may be a new species, and we set to analyze the ITS2 sequences of some Euphorbia species. The results show that the new taxon belongs to the sect. Esula of Euphorbia subg. Esula. It is similar to Euphorbia esula (description from Flora of China) but does not belong to the same species. Concomitantly, plant morphological data and pollen morphology results show significant differences between the new taxon, E. esula and E. caesia, a finding that supports the delimitation of this new taxon, which is named Euphorbia mongoliensis in accordance with its geographical distribution.

A new species of Andinobates (Dendrobatidae) is described from the East Andes of Colombia, just 37 km away from the Colombian capital, Bogotá. Andinobates supata sp. nov., represents the second known species of yellow Andinobates, and can be distinguished from the other, Andinobates tolimensis, by an unique combination of ventral and dorsal color patterns. Our phylogenetic analyses, based on ≈ 1120 bp from two mitochondrial markers (16S rRNA and cytochrome b) showed that this new taxon is sister to a clade formed by A. cassidyhornae, A. bombetes, A. opisthomelas, A. tolimensis and A. virolinensis. The new species appears to be restricted to a handful of small forest fragments (<10 ha) distributed in no more than 5 km2, between 1800–2000 m elevation, where the human activity is high. In addition, more than 90% of the original forest has been logged at the type locality, and its watersheds receive considerable agrochemical discharges. Altogether, the evidence suggests that this new species should be listed as Critically Endangered and should receive immediate attention regarding basic research and urgent conservation measures.
