Anal spine rather short with strong granular papillae (Fig. 14). Etymology. The species has been named after the type locality. Discussion. The new species belongs to Deharveng&#x2019;s (1981) group 1 &#x2013;&#x2013; lamellifera group with two anal spines, three to five subequal dental chaetae. According to reduced number of dental chaetae this species is related to the subgroup formed by S. alpina Deharveng &amp; Izarra, 1979 (Savoie, France), S. delamarei Rusek, 1991 (Bohemia, Czech Republic), S. proxima Deharveng &amp; Izarra, 1979 (Pyr&#xE9;n&#xE9;es-Orientales, France), S. selgae Arbea, 1990 (Navarra, Spain), S. subalpina Arbea, 1990 (Navarra, Spain) and S. vallvidrerensis Selga, 1966 (Northern Spain). Main differences between S. tayaensis sp. nov. and these species are summarized in Table 2. The new species is most similar to S. subalpina. They differ in the number of tibiotarsal chaetae and the sensilar chaetotaxy of Ant IV. The number of sensilla on Ant IV given in the literature for Superodontella species should be taken with caution because some chaetae tend to be longer, blunt and more refringent than ordinary chaetae, looking like thin schaetae difficult to distinguish from mou-chaetae.</description><description>Published as part of Arbea, Javier I., Brahim-Bounab, Hayette &amp; Kroua, Salah Hamra, 2013, Collembola Poduromorpha from Guelma Province (Northeastern Algeria), with description of a new Superodontella species (Collembola: Odontellidae), pp. 177-184 in Zootaxa 3709 (2) on pages 178-182, DOI: 10.11646/zootaxa.3709.2.5, http://zenodo.org/record/219429</description><identifier>https://zenodo.org/record/6151211</identifier><identifier>10.5281/zenodo.6151211</identifier><identifier>oai:zenodo.org:6151211</identifier><relation>info:eu-repo/semantics/altIdentifier/url/http://treatment.plazi.org/id/1E482D44FFE9F47DFF36F99C91F3F937</relation><relation>doi:10.11646/zootaxa.3709.2.5</relation><relation>url:http://zenodo.org/record/219429</relation><relation>url:http://publication.plazi.org/id/E271553CFFE8F478FFA1FFD39336FFC3</relation><relation>doi:10.5281/zenodo.219430</relation><relation>doi:10.5281/zenodo.219431</relation><relation>doi:10.5281/zenodo.219432</relation><relation>url:http://zoobank.org/BE65D2AB-00C7-456C-ACAC-530DA96386E0</relation><relation>doi:10.5281/zenodo.6151210</relation><relation>url:https://zenodo.org/communities/biosyslit</relation><rights>info:eu-repo/semantics/openAccess</rights><rights>https://creativecommons.org/publicdomain/zero/1.0/legalcode</rights><source>Collembola Poduromorpha from Guelma Province (Northeastern Algeria), with description of a new Superodontella species (Collembola: Odontellidae), pp. 177-184 in Zootaxa 3709(2) 178-182</source><subject>Biodiversity</subject><subject>Taxonomy</subject><subject>Animalia</subject><subject>Arthropoda</subject><subject>Entognatha</subject><subject>Collembola</subject><subject>Odontellidae</subject><subject>Superodontella</subject><subject>Superodontella tayaensi</subject><title>Superodontella tayaensi Arbea, Brahim-Bounab &amp; Kroua, 2013, sp. nov.</title><type>Other:info:eu-repo/semantics/other</type><type>Other:publication-taxonomictreatment</type><recordID>6151211</recordID></dc>
