Revision ofVesiculentomon, Nosekientomonn. g. (Protura: Acerentomidae, Nipponentominae), and a Key to Genera of Nipponentominae

Abstract

Based on recent reexamination of types, Vesiculentomon rusekiNosek, 1977, differs significantly from Vesiculentomon marshalliRusek, 1974, in composition and shape of maxillary gland, number of anterior setae on metanotum, and shape of foretarsal sensillum t1. A new genus Nosekientomon is erected for V. ruseki. Nosekientomon n. gen. is characterized by three pairs of anterior setae on the metanotum, claviform foretarsal sensillum t1, and a smooth globular vesicle on the calyx of the maxillary gland. Vesiculentomon Rusek has four pairs of anterior setae on the metanotum, baculiform foretarsal sensillum t1, and a large vesicle near the calyx with dense granulation along its narrow proximal part. The original descriptions are corrected and supplemented with new characters, including head chaetotaxy, setal lengths, and porotaxy. A key to world genera of Nipponentominae is provided.

Revision of the GenusAndinentulus(Protura: Acerentomidae: Berberentulinae), with a Key to South and Central American Acerentomidae Species

“…Additionally, it differs from Najtentulus by the shape of the foretarsal sensillum t3 (finger-like in Acerentuloides, cylindrical in Najtentulus). The presence of a vesicle on the maxillary gland is found in only a few genera (Vesiculentomon Rusek, 1974, Nosekientomon (Nosek, 1977), Callientomon Yin, 1980, and Acerella Berlese, 1909, but they belong to other subfamilies of Acerentomidae (Tuxen 1964;Shrubovych et al 2014a). …”

Protura in Arctic Regions, with Description of Mastodonentomon n. gen. (Acerentomidae, Nipponentominae) and a Key to Known Arctic Taxa

“…The majority of these proturans were described as Acerentulus canadensis Tuxen, 1955, and six specimens from one sample as Nosekiella condei Tuxen, 1955 (Table 1). Currently, these species are in the genera Verrucoentomon and Vesiculentomon, respectively [19,22]. Hammer's collection contained one specimen belonging to the genus Eosentomon.…”

Genera of the Protura of the World: diagnosis, distribution, and key

“…Nosek’s (1978a) diagnostic framework is partly used and integrated with the new genera described and updated in accordance with the more recent taxonomic revisions and redescriptions of Nakamura (2010), Shrubovych and Rusek (2010), Shrubovych et al (2012a), Shrubovych and Smykla (2012), Shrubovych et al (2014b).…”

“…Parts concerning the Acerentominae and Nipponentominae genera are taken from Shrubovych and Rusek (2010) and Shrubovych et al (2014b), respectively. The previous key for Acerentomidae genera by Tuxen (1984) was also used as a reference.…”

“…For example, the number of worldwide genera cited by Tuxen (1964), Nosek (1978a), Yin (1983) and Szeptycki (2007) was 22, 40, 54 and 72, respectively. Four new genera ( Nanshanentulus Bu & Yin, 2007, Osientomon Nakamura, 2010, Liaoxientulus Wu & Yin, 2011, Nosekientomon Shrubovych et al, 2014b) have been described after the publication of Szeptycki’s Catalogue (2007), but since Yin (1983) there has not been published an updated key for the worldwide genera of Protura. In the belief that such a key is an essential tool for those researchers who want to study in detail this still poorly known taxon, this paper describes the diagnostic characters of the 76 genera known to date worldwide, accompanied by a key for their identification.…”
