[Herpetology • 2020] Hemidactylus flavicaudus & H. xericolus • Two New Species of Yellow-tailed Hemidactylus Goldfuss, 1820 (Squamata: Gekkonidae) from Rocky Outcrops on the Telangana Plateau, India


Hemidactylus flavicaudus Hxericolus 
Lajmi, Giri, Singh & Agarwal, 2020


Abstract

Two distinct species of the gekkonid genus Hemidactylus are described from the dry zone of peninsular India from the state of Telangana. The two sister species, Hemidactylus flavicaudus sp. nov. and Hxericolus sp. nov., are nested within the morphologically cryptic H. brookii group, but are clearly distinguishable from all known species in having a bright yellow tail and yellow markings on the head, besides unique combinations of meristic characters and small body size (< 45 mm snout to vent length). The two new species are also deeply divergent from each other and other members of the H. brookii group in mitochondrial NADH dehydrogenase 2 and cytochrome b sequences. Hemidactylus flavicaudus sp. nov. can be diagnosed from H. xericolus sp. nov. based on the number of dorsal tubercle rows at midbody (11–14 versus 6–8). These descriptions of evolutionarily and morphologically distinct species highlight the dearth of studies carried out in the dry zone of peninsular India and the urgent need to assess biodiversity in the face of rapid land-use changes in this landscape.

 Pati, Thackeray & Pawar. 2023


Abstract
Ghatiana sanguinolenta sp. nov. is recognized herein as the twelfth species of the gecarcinucid genus Ghatiana Pati & Sharma, 2014, and the fifth species of the genus from the Karnataka state. This new species of freshwater crab is currently known only from the type locality, which is situated in the Central Western Ghats of India. Ghatiana sanguinolenta sp. nov. can be immediately distinguished from congeners by the outwardly curved ultimate article of the male first gonopod and the dark blood-red colour in life.

[Botany • 2023] Cirsium tukuhnikivatzicum (Asteraceae) • A New Species of Thistle endemic to the La Sal Mountains of Utah, USA


  Cirsium tukuhnikivatzicum Ackerf.,

in Ackerfield, 2023. 

Abstract
Cirsium (thistles) have long been considered one of the most taxonomically challenging groups of plants in western North America. However, the relationships among thistles have become clearer thanks to recent molecular phylogenetic work. The results of this work revealed that Cirsium eatonii var. eriocephalum was polyphyletic, consisting of three distinct evolutionary lineages. Each of these lineages was also found to be distinct morphologically as well as geographically. Multiple lines of evidence thus indicated that Cirsium eatonii var. eriocephalum consisted of at least three distinct species. The first species recognized was the previously named C. scopulorum. The second lineage was recently named and described as Cirsium funkiae. The third lineage is here described as a new speciesCirsium tukuhnikivatzicum. Mount Tukuhnikivatz is a prominent backdrop against this new species of thistle. Tukuhnikivatz is also the Southern Paiute word for “place where the sun shines longest” and Ute word for “where the sun sets last.” The specific epithet tukuhnikivatzicum is therefore used to indicate the distribution of this species, while also acknowledging and paying tribute to the Southern Paiute and Ute legacy of use of the La Sal Mountains. There was a taxonomic lag time of 112 yr between the first specimen collection and the new species description presented here.

Abstract
Psaironeura angeloi sp. nov. (Holotype male deposited in FSCA: ECUADOR, Esmeraldas Province, small stream 5.6 km NW of Lita, 00.893°N 78.510°W, 4.II.1997, KJT leg.) is described and illustrated based on specimens from Ecuador, Panama, Costa Rica, and Nicaragua, bringing the total number of species in the genus to five. The new species is closely related to P. remissa (Calvert), a Mexican/northern Central American species with broad, foliate male cerci, but is distinct in that the long flagella of the genital ligula lack a small sharp spine unique to P. remissa, labrum and clypeus are orange-red, and the back of the head is mostly pale in both males and females. In life, the eyes of the new species are bright red in males versus green and black in P. remissa.

in Saba, Khalid et Sarwar, 2023. 
 Scale bars: 10 mm 

Abstract
Within the family Inocybaceae, many species of Mallocybe have been reported, but there are only a few reports of this genus from Pakistan. In this study, six collections of Mallocybe were studied by morphological and phylogenetic methods. Phylogenetic analyses, based on sequence data from two different loci (ITS and LSU) using Maximum Likelihood and Maximum Parsimony methods, have been performed to infer species relationships within Mallocybe. Results indicated that these six collections encompass two new species of Mallocybe i.e. M. pakistanica and M. pinicola, from Pakistan. Their detailed morphological descriptions and illustrations are also provided. In addition, comparison with morphologically closely-related taxa is also discussed. Previously, only two species of this genus have been recorded from Pakistan and, with this addition, the total number of reported taxa of Mallocybe has been raised to four from Pakistan. A key to the described taxa of Mallocybe from Pakistan is also provided.

 Mallocybe pakistanica Saba & Khalid, sp. nov.
 
Diagnosis: Most similar to Mallocybe myriadophylla described from north-western Europe, but differs by the absence of a crowded lamellae, different pileal colouration and somewhat larger basidiospores. Phylogenetically separated from other species of Mallocybe due to unique ITS and LSU sequences.

Etymology: Referring to the country where it was discovered.


 Mallocybe pinicola Saba & Khalid, sp. nov.
 
Diagnosis: Most similar to M. siciliana and M. subtomentosa, but differs by the combination of pileal colour, absence of umbo, size of basidiospores, pyriform to broadly clavate, catenate cheilocystidia and an ecological association with Pines. Phylogenetically separated from other species of Mallocybe due to unique ITS and LSU sequences.

Etymology: Referring to its exclusive association with Pinus.

Abstract
The explosive diversity of rainfrogs (Pristimantis spp) reaches its highest levels in the mountains of the Tropical Andes, with remarkable cryptic species mainly in unexplored areas of Ecuador. Based on phylogenetics, morphometric traits, skull osteology and bioacoustics, we describe two new species of Pristimantis, previously confused with Pristimantis gladiator, that belong to the subgenus Trachyphrynus traditionally known as the Pristimantis myersi species group. The two new taxa are closely related, but have allopatric distributions. We discuss the importance of the Quijos and Pastaza River valleys in the diversification along Amazonian slopes of the Ecuadorian Andes.

Abstract
We revise the Chilean genus Porteria, including the type species, Porteria albopunctata, and 11 new species: Porteria ajimayo sp. nov., Porteria alopobre sp. nov., Porteria ariasbohartae sp. nov., Porteria bunnyana sp. nov., Porteria contulmo sp. nov., Porteria correcaminos sp. nov., Porteria eddardstarki sp. nov., Porteria faberi sp. nov., Porteria fiura sp. nov., Porteria misbianka sp. nov. and Porteria torobayo sp. nov. A phylogenetic analysis using six genetic markers confirms the monophyly of Porteriinae, including Baiami and the core porteriines, here defined to include the ecribellate genera Cambridgea, Corasoides, Nanocambridgea and Porteria. Core porteriines are diagnosed by a narrowed section of the piriform gland spigot field, the cymbium extended to a narrow tip and lack of a median apophysis. Porteria and Corasoides are sister taxa, united by the behaviour of running atop the sheet of a web and by spinning a regular square mesh in the web platform. According to our results, the diversification of Porteria started about 30 Mya (44–17 Mya). A biogeographic analysis infers that an ancestor of Porteria reached South America via a founder event from Australia or New Zealand, where their close relatives occur.

[Crustacea • 2023] Hyalella yashmara • A New thermal Species of the Genus Hyalella (Amphipoda) from Peru with Molecular Phylogeny of the Family Hyalellidae


Hyalella yashmara 
Tomikawa, Kawasaki, Leiva & Arroyo, 2023


Abstract
In recent years, the impact of rising water temperatures associated with global warming on cold-water freshwater organisms has become a major issue, and understanding the physiological and ecological elements that support temperature limits is essential for the conservation biology of freshwater organisms. We describe a new species of thermophilic hyalellid amphipod, Hyalella yashmara sp. nov. from the Peruvian hot spring Baños del Inca Cajamarca and this could potentially contribute to understanding the high temperature preference of these. We found that this new species can live in water temperatures ranging from 19.8 to 52.1°C, that, to our knowledge, is the highest recorded habitat temperature of amphipods. Hyalella yashmara sp. nov. is most similar to H. meinerti Stebbing, 1899 from Peru. However, this new species differs from the latter in features of gnathopods 1 and 2, sternal gills, uropod 3 and telson. A detailed morphological comparison between Hyalella yashmara sp. nov. and Peruvian species is also provided. Our molecular phylogenetic analyses based on the nuclear 28S rRNA and mitochondrial cytochrome c oxidase subunit I (COI) gene sequences strongly support the monophyly of Hyalellidae (=Hyalella). Since Hyalellidae was found to form a sister group with Chiltoniidae, these two families were expected to have originated from a common ancestor that invaded freshwater habitats from marine environments when the continents of South America, Africa and Australia were united as Gondwana. Our findings suggest that the South American species of Hyalella are not monophyletic and that the North American species are likely to share a most recent common ancestor with H. yashmara sp. nov.

[Herpetology • 2023] Litoria ridibunda • Revision of Litoria rothii (Anura: Pelodryadidae) from northern Australia


 Litoria ridibunda
Donnellan, Catullo, Rowley, Doughty, Price, Hines & Richards, 2023


Abstract
Litoria rothii is a widespread pelodryadid frog with a charismatic “laughing” advertisement call, distributed across the Australian Monsoon Tropics and southern New Guinea. Given its large distribution spanning well-known biogeographic barriers, variation in male advertisement calls and the prevalence of unresolved species complexes in the Australian frog fauna, we examine the genetic, morphological and acoustic diversity in the species from across its range. Our analyses reveal the presence of a previously unrecognised species in western parts of the range of L. rothii sensu lato, which we describe herein as a new species. Litoria ridibunda sp. nov. is distinguished from L. rothii on the basis of paraphyly of nuclear gene trees with L. everetti from Indonesia, colour patterns on the posterior thigh and male advertisement calls. Compared to L. rothii, the new species has a less contrasting pattern on the posterior thigh and a male advertisement call with a greater number of notes per call and a greater call duration. In particular, the magnitude of call differences between the species is highest where the ranges of the two species are in proximity in north-western Queensland. Our study further emphasises the undiagnosed diversity that remains in Australian frogs, even in relatively large, charismatic, frequently encountered species that often share human dwellings.
