A New Species

Hetaerina americana Fabricius, 1798 has a long and irresolute taxonomic history. Several synonyms have been suggested (H. californica Hagen in Selys-Longchamps, 1859, H. basalis Hagen in Selys-Longchamps, 1859, H. texana Walsh, 1863, H. scelerata Walsh, 1863, etc.), related to the variation in the size of the wing spots as well as to the morphology of the male cerci. However, Calvert (1901) suggested that H. americana represents one variable species. Nevertheless, Vega-Sánchez et al. (2019) through a genetic and morphological analysis presented evidence to propose that H. americana represents a species complex. In the present work, we describe a new species that belongs to this complex: H. calverti sp. nov. The morphological characteristics by which males and females of H. calverti differ from H. americana are highlighted. The most important character for the differentiation of males is the shape of the cerci and the size of the individuals (when the two species are in sympatry). In females, the main differences are in the shape of the intersternites and the medio-dorsal carina of the last segment of the abdomen. Some generalities about the biology of the species are presented, including geographical distribution patterns and genetic divergence data.

A New Species

ABSTRACT The sciaenid genus Bairdiella comprises a group of relatively small fishes found in inshore waters and estuaries of the western Atlantic and eastern Pacific. Despite recent analyses of the phylogenetic relationships of Bairdiella, there has been no comprehensive revision of the alpha taxonomy of the species of the genus. Bairdiella ronchus from the western Atlantic, has a complex taxonomic history, with four junior synonyms recognized. Based on morphological and molecular evidence, this study indicates that B. ronchus represents a species complex. The species is therefore redescribed and its geographic range is redefined. Bairdiella veraecrucis, which is currently recognized as a junior synonym of B. ronchus, is revalidated, and a new species of the genus is described from the Atlantic coast of Brazil. Finally, inferences are made on the diversity and biogeography of the B. ronchus species complex.

A New Species

A new species of Austrolebias is described based on individuals from the middle and upper río Negro (río Uruguay basin) and río Yaguarón (Patos-Merín system). The new species can be differentiated from all other species of the genus by the unique presence in males of uniform bluish gray pigmentation on flanks (without vertical bands) and unpaired fins. The new species is also distinguished by the combination of characters associated with a reduction of the squamation of the abdominal, preopercular, and opercular regions. The new species presents some morphological characteristics similar to A. gymnoventris and A. luteoflammulatus. The distribution of the new species is concordant with three other species of Austrolebias and may represent a case of drainage rearrangement of the río Negro upstream tributaries (río Uruguay basin) and tributaries of laguna Merín system.

A New Species

The Neotropical genus Propetes Walker, 1851 currently includes three species recorded from Brazil and Guyana that share morphological characteristics related to wasp-mimicking behavior. A revision of available material of Amazonian Propetes was conducted, and a new species, P. sakakibara sp. nov., is described and illustrated herein based on males from Brazil, Peru, and Venezuela. Based on the association of males and females from Pará State (Brazil), a synonymy is proposed between P. triquetra (Fabricius, 1803) (previously known only from males) and P. compressa Walker, 1851 (previously known only from females). The female genitalia of P. triquetra is redescribed and illustrated in detail. Observation of bluffing display behavior is reported for the first time for the genus, in P. schmidti. A key to all species included in Propetes, based on males and females, and a map of distribution of Propetes species are provided, including new records of the genus from French Guiana, Peru, and Venezuela.

In this paper we summarize the taxonomic history of Pleurothallis crocodiliceps Rchb.f. and demonstrate that the species described by Reichenbach did not possess the stereotypical minute, pubescent, tri-lobed lip, with basal lobes modified into “horns”. The first two species described with such a lip were P. arietina and P. nelsonii. Rather than a single widely distributed, variable species, with a morphologically constant lip, P. crocodiliceps, we recognize the P. arietina-P. nelsonii species complex. Herein we describe four new species in this complex and discuss the morphological characters useful in distinguishing among the members of the complex. We also discuss the nature of the lip possessed by members of this complex and propose that it may mimic a female insect luring a male fly into pollinating the flower by pseudocopulation.

During an investigation into the microfungi on Dracaena fragrans in Thailand, a saprobic taxon belonging to Glomerellaceae was collected. Based on morphological characterization and combined phylogenetic analyses of ITS, GAPDH, CHS-1, ACT and TUB2 sequence data from the sexual and asexual morphs our taxon was identified as a new species of Colletotrichum. Colletotrichum dracaenigenum sp. nov. is introduced here with a full description, colour photographs of morphological characteristics and a phylogenetic tree to show the placement of the new taxon in the gloeosporioides species complex.

A New Species

Despite being recognized as ecologically and biogeographically important, the biodiversity of the Hengduan Mountain Region, particularly along the upper Mekong River, remains poorly understood. Here we describe a new species of Mountain Dragon of the genus Japalura sensu lato Gray, 1853 from the headwater region of the Mekong River in Chamdo, Tibet Autonomous Region, China. The species is recognized as a member of the Japalura flaviceps Barbour & Dunn 1919 complex, and it can be distinguished readily from all congeners by a suite of morphological characteristics, including its dwarf appearance (small body size and disproportionally short tails and short hind limbs), smooth or weakly keeled ventral scales, feebly developed vertebral crests in males, and by the absence of distinct gular spots in males and females. In addition to the description of the new species, we also report morphological variations and range extensions of two recently described congeners along the same river, namely J. iadina and J. vela. We discuss the distribution patterns of the genus in the Hengduan Mountain Region and the urgent conservation priorities for protecting Japalura species along the Mekong River. According to our best available data, we provided IUCN assessments of the three species and propos to list them as nationally protected under the Chinese Wildlife Protection Act.

A New Species

The Asian Temple Pitviper Tropidolaemus wagleri is a widespread polytypic species complex with a complicated taxonomic history, a lengthy species synonymy list, and a geographic distribution encompassing Vietnam, Thailand, Malaysia, Singapore, Brunei, portions of Indonesia, and the Philippines. As a prelude to a comprehensive review of this species complex, we describe a new species of Temple Pitviper based on five historic museum specimens from the Indonesian island of Sulawesi. The new species can be distinguished from sympatric members of the Tropidolaemus subannulatus complex and other congeners on the basis of its conspicuous color pattern and scalation characters. Available collecting data suggest that the new species has a wide distribution in rainforests and lower montane wet forests of Sulawesi Utara and Sulawesi Tengah provinces.

A New Species

A new species of chameleon, Trioceros wolfgangboehmeisp. nov., inhabiting the northern slopes of the Bale Mountains in Ethiopia, is described. It differs from its Ethiopian congeners by a combination of the following features: presence of a prominent dorsal crest with a low number of enlarged conical scales reaching along the anterior half of the tail as a prominent tail crest, a casque raised above the dorsal crest, heterogeneous body scalation, long canthus parietalis, rugose head scalation, high number of flank scales at midbody and unique hemipenial morphology. Based on morphological characteristics, phylogenetic discordances of previous studies and biogeographical patterns, this new species is assigned to the Trioceros affinis (Rüppell, 1845) species complex. An updated comprehensive key to the Trioceros found in Ethiopia is provided.

A new species of sea spider is described from the Great Barrier Reef, Australia. Anoplodactylus perissoporus n.sp. is in a species complex of extremely slender and tenuous forms that have serrated heel spines and are known to inhabit Indo- West Pacific coral reefs. The new species is characterized by the multiple cement gland pores on femora of males. Otherwise the species is very similar to, and probably closely related to A. tenuicorpus. The species boundaries within the A. tenuicorpus complex are difficult to discern and are not clearly defined, especially for females. Other character sets seem necessary to indicate affinities and distribution patterns of the tenuicorpus complex.

A new species of the Yellow Sally genus (Isoperla Banks, 1906) is described, based on morphological (males and females adults, larval and egg) and molecular (the barcode region of the cytochrome c oxidase subunit I gene (COI)) features. Popijač’s Yellow Sally, I. popijaci Hlebec & Sivec, sp. nov. inhabits two karstic sources of the Krasulja rivulet in Croatia. Male and female of the new species are characterised by colouration patterns of the head and pronotum; the dimensions of the female subgenital plate; the medial penial armature and oval-shaped egg without collar and anchor. The larvae differ from their congeners by the uniquely coloured head and pronotum. Based on morphological characteristics I. popijacisp. nov. belongs to the I. tripartita species group. Phylogenetic and taxonomic relationships were reconstructed using three methods of phylogenetic inference and three species delimitation methods. As I. popijacisp. nov. occurs at a narrow area of the Krasulja rivulet in Krbava field, the study puts emphasis on the conservation and hotspot importance of the temporary rivers in the Dinaric karst. Furthermore, the study accentuates the necessity for further research on the genetic diversity of Plecoptera in Croatia.
