Hájek, Jiří & Kabátek, Petr, 2012, Synonymical notes on the genus Sybrinus from Socotra Island (Coleoptera: Cerambycidae: Lamiinae), Acta Entomologica Musei Nationalis Pragae 52, pp. 365-372 : 366-369

Sybrinus Gahan, 1900

Sybrinus Gahan, 1900: 12 (type species S. commixtus Gahan, 1900 , by monotypy); AURIVILLIUS (1922): 299 (catalogue); ADLBAUER (2010): 227 (catalogue).

Arabosybrinus Breuning, 1948: 16 (type species S. flavescens Breuning, 1948 , by original designation).

Sokotrosybrinus Breuning, 1949: 21 (type species S. simonyi Gahan, 1903 , by original designation).

GAHAN (1900) described the genus Sybrinus based on the single species S. commixtus Gahan, 1900 from Socotra Island, and placed it close to the genus Sybra Pascoe, 1865 , within the group ‘Ptericoptides’. GAHAN (1903) redescribed the genus and added one new species, again from Socotra Island. In accordance with GAHAN’ s (1900) original description, AURIVILLIUS (1922) catalogued Sybrinus within the tribe Ptericoptini , and named one variety mentioned in GAHAN (1903). Subsequently BREUNING (1948) described two new species from ‘Aden’ in the new subgenus Arabosybrinus Breuning, 1948 , BREUNING (1949) created a new subgenus Sokotrosybrinus Breuning, 1949 based on the Socotran S. simonyi , and BREUNING (1950) added three new species of Sybrinus from east Africa. In addition, BREUNING (1978) described two more Afrotropical Sybrinus , those were, however, synonymised with species of the genus Nyoma Duvivier, 1892 by SUDRE & TÉOCCHI (2005) and TÉOCCHI et al. (2008). HOLZSCHUH & TÉOCCHI (1991) listed both Arabian species, noted that they were erroneously placed in the genus Sybrinus and transferred them to genus Sophroniella Breuning, 1943 . However, most recently, JIROUX et al. (2004) overlooked this synonymy and described a third Socotran taxon: Sybrinus (Arabosybrinus) albosignatus sokotrensis Jiroux, Sudre & Téocchi, 2004 . Subsequently, TÉOCCHI et al. (2007) elevated the subspecies to specific rank, added two more new species, but also listed S. commixtus within the subgenus Arabosybrinus and assumed S. simonyi to be its synonym. Since S. commixtus and S. simonyi are the type species of their respective subgenera, by doing this TÉOCCHI et al. (2007) in fact informally synonymised all Sybrinus subgenera – which was formally published by SAMA (2010). SAMA (2010) also established a formal synonymy of Sybrinus with Sophroniella , currently a junior synonym of Nyoma ( Sophronica punctata Jordan, 1894 , type species of Sophroniella , is considered to be a junior subjective synonym of Nyoma parallela Duvivier, 1892 , type species of Nyoma ). Since the synonymy of Sybrinus and Nyoma is not based on study of type species, we retain, in accordance with TÉOCCHI et al. (2009), both genera as valid, pending a comprehensive revision of the group.

After the synonymy presented below, the genus Sybrinus contains seven species occurring in east Africa (3 species), Socotra Island (3 species) and continental Yemen (2 species).
