| 2:01a | [Arachnida • 2023] Porteria ajimayo, P. correcaminos, P. eddardstarki, etc. • A Revision of the Genus Porteria and the Phylogeny and Biogeography of Porteriinae (Araneae: Desidae)
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.

| 2:41a | [Herpetology • 2023] Pristimantis donnelsoni & P. kayi • Two New Species of Terrestrial Frogs of the Pristimantis gladiator Complex (Anura: Strabomantidae) from the Ecuadorian Andes, with insights on their Biogeography and Skull Morphology
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. Key words: Cryptic species, Ecuadorian Andean slopes, osteology, Pristimantis taxonomy

| 9:55a | [Fungi • 2023] Mallocybe pakistanica & M. pinicola (Agaricales: Inocybaceae) • New Species of Mallocybe from Pakistan, based on Morphological and Molecular Evidence
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. Key words: Asia, molecular systematics, phylogeny, Pinaceae
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.

| 11:20a | [Entomology • 2016] Psaironeura angeloi • A New Species of Damselfly (Zygoptera: Coenagrionidae) from Central and South America
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.

| 11:30a | [Botany • 2023] Cirsium tukuhnikivatzicum (Asteraceae) • A New Species of Thistle endemic to the La Sal Mountains of Utah, USA
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 species, Cirsium 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.

| 11:34a | [Crustacea • 2023] Ghatiana sanguinolenta • A New Species of Freshwater Crab (Brachyura: Gecarcinucidae) from the Central Western Ghats of India
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.

| 11:44a | [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
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 H. xericolus 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.
