A survey of pholcid spiders (Araneae, Pholcidae) from Guiyang, Guizhou Province, China https://zookeys.pensoft.net/article/105736/ ZooKeys 1186: 175-184

DOI: 10.3897/zookeys.1186.105736

Authors: Lan Yang, Fangyu Zhao, Qiaoqiao He, Zhiyuan Yao

Abstract: The family Pholcidae C.L. Koch, 1850 is highly diverse in Guizhou Province, southwestern China, and currently contains four genera and 22 species. Nevertheless, the distribution of pholcid spiders is conspicuously patchy in Guizhou. Species from Guiyang are poorly studied, and only Pholcus spilis Zhu & Gong, 1991 has been recorded. A survey was undertaken for the first time to study the pholcids in Guiyang. A total of four species are reported, comprising Belisana yuhaoi Yang & Yao, sp. nov. and three other species: Leptopholcus tanikawai Irie, 1999 (new record for Guiyang), Pholcus spilis Zhu & Gong, 1991 and Spermophora senoculata (Dugès, 1836) (new record for Guizhou).

To be or not to be… Integrative taxonomy and species delimitation in the daddy long-legs spiders of the genus Physocyclus (Araneae, Pholcidae) using DNA barcoding and morphology https://zookeys.pensoft.net/article/94628/ ZooKeys 1135: 93-118

DOI: 10.3897/zookeys.1135.94628

Authors: Samuel Nolasco, Alejandro Valdez-Mondragón

Abstract: Integrative taxonomy is crucial for discovery, recognition, and species delimitation, especially in underestimated species complex or cryptic species, by incorporating different sources of evidence to construct rigorous species hypotheses. The spider genus Physocyclus Simon, 1893 (Pholcidae, Arteminae) is composed of 37 species, mainly from North America. In this study, traditional morphology was compared with three DNA barcoding markers regarding their utility in species delimitation within the genus: 1) Cytochrome c Oxidase subunit 1 (CO1), 2) Internal Transcribed Spacer 2 (ITS2), and 3) Ribosomal large subunit (28S). The molecular species delimitation analyses were carried out using four methods under the corrected p-distances Neighbor-Joining (NJ) criteria: 1) Automatic Barcode Gap Discovery (ABGD), 2) Assemble Species by Automatic Partitioning (ASAP), 3) General Mixed Yule Coalescent model (GMYC), and 4) Bayesian Poisson Tree Processes (bPTP). The analyses incorporated 75 terminals from 22 putative species of Physocyclus. The average intraspecific genetic distance (p-distance) was found to be < 2%, whereas the average interspecific genetic distance was 20.6%. The ABGD, ASAP, and GMYC methods were the most congruent, delimiting 26 or 27 species, while the bPTP method delimited 33 species. The use of traditional morphology for species delimitation was congruent with most molecular methods, with the male palp, male chelicerae, and female genitalia shown to be robust characters that support species-level identification. The barcoding with CO1 and 28S had better resolution for species delimitation in comparison with ITS2. The concatenated matrix and traditional morphology were found to be more robust and informative for species delimitation within Physocyclus.

Notes on two closely related spider species of the Pholcus phungiformes species group (Araneae, Pholcidae) from Beijing, China https://zookeys.pensoft.net/article/56199/ ZooKeys 965: 1-16

DOI: 10.3897/zookeys.965.56199

Authors: Xiang Wang, Shumaila Shaheen, Qiaoqiao He, Zhiyuan Yao

Abstract: The Pholcus phungiformes species group is highly diverse and currently contains 53 species. In this study, Pholcus tongyaoi Wang & Yao, sp. nov. (male, female) from Huairou District, Beijing, China is described while similar congener Pholcus lexuancanhi Yao, Pham & Li, 2012 from neighboring Haidian District (type locality) is redescribed; the female of P. lexuancanhi is described for the first time. In addition, the DNA barcode COI for the two species was obtained to estimate p-distance.

The phylogeny of pholcid spiders: a critical evaluation of relationships suggested by molecular data (Araneae, Pholcidae) https://zookeys.pensoft.net/article/22781/ ZooKeys 789: 51-101

DOI: 10.3897/zookeys.789.22781

Authors: Bernhard A. Huber, Jonas Eberle, Dimitar Dimitrov

Abstract: With almost 600 species, the latest molecular phylogeny of pholcid spiders (Eberle et al. 2018, BMC Evolutionary Biology) more than triples the largest previously available molecular phylogeny of the family. At the level of genera, the coverage is high (86%, i.e., 75 of the 87 named genera), and at the level of subfamilies it is complete. The present paper is an effort to critically evaluate the implications of this phylogeny for pholcid systematics. The analyses largely support the division of Pholcidae into five subfamilies: Ninetinae, Arteminae, Modisiminae, Smeringopinae, and Pholcinae. Their compositions are largely unchanged except that Chisosa Huber, 2000 is moved from Ninetinae to Arteminae. The positions of Artema Walckenaer, 1837 and Priscula Simon, 1893 in this system remain dubious. Relationships among subfamilies remain weakly supported, except for the sister group relationship between Smeringopinae and Pholcinae. Several major clades within subfamilies are separated from each other along geographical boundaries; for example within Modisiminae a South American clade and a Central + North American + Caribbean clade, and within Smeringopinae a Sub-Saharan clade and a clade ranging from the Mediterranean to Central Asia. Central + North American + Caribbean clades in both Ninetinae and Modisiminae may originate from South American ancestors. Many taxonomic changes are suggested by the data, some of which are formally implemented herein. Two new genera result from the splitting of Calapnita Simon, 1892 and Panjange Deeleman-Reinhold & Deeleman, 1983, respectively: Nipisa Huber, gen. n.; and Apokayana Huber, gen. n. Nine new genera result from splitting of Pholcus: Cantikus Huber, gen. n.; Kelabita Huber, gen. n.; Kintaqa Huber, gen. n.; Muruta Huber, gen. n.; Meraha Huber, gen. n.; Paiwana Huber, gen. n.; Pribumia Huber, gen. n.; Teranga Huber, gen. n.; and Tissahamia Huber, gen. n. Two genera are newly synonymized: Platnicknia Özdikmen & Demir, 2009 is synonymized with Modisimus Simon, 1893; Sihala Huber, 2011 is synonymized with Pholcus Walckenaer, 1805. Pholcus agadir Huber, 2011 is moved to Micropholcus Deeleman-Reinhold & Prinsen, 1987, resulting in the new combination Micropholcus agadir (Huber, 2011).
