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

Abstract

The species Acerentulus rapoportiCondé, 1963 is redescribed, transferred to genus AndinentulusTuxen, 1984, and synonymized with Andinentulus ebbeiTuxen, 1984 on the basis of type series. Andinentulus rapoporti (Condé, 1963) comb. nov. is characterized by very long and sword-shaped foretarsal sensillum a' sensillum b that is half the length of sensillum c, presence of additional seta d6 on the head, absence of seta P1a on abdominal tergites I–VI, and short oblong accessory setae on tergites I–VI. The differences between the genus Andinentulus and morphologically similar genera, which have three setae on the abdominal legs, are discussed. A key to South and Central American Acerentomidae species and their distribution in America is provided. The mitochondrial cytochrome oxidase subunit I sequence (barcode) is provided for several specimens of the species and compared with other proturan barcodes with a phylogenetic analysis.

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

“…Nevertheless, nearly 20% of 76 genera known worldwide [5] have been found in the region. Members of the widespread genus Eosentomon, which are very abundant and diverse in the Americas and Europe [36][37][38], are poorly represented, with only four known species, and restricted in distribution to Alaska and Northern Canada (Table 1). However, the lack of Eosentomon in the Siberian Arctic is not surprising because species of this genus are generally rare and not numerous in neighboring regions [18,39].…”

“…26,30,(32)(33)(34). sternite VIII, but differ from Acerentuloides by having a reduced labial palpus with 3 setae and a sensillum, and in reduction of the striate band to 2 lines without visible striae (Nosek 1973;Shrubovych & Bernard 2013;Shrubovych et al 2014c). Acerentuloides is morphologically close to the genera Acerentulus and Najtentulus, differing from them by the peculiar shape of the maxillary gland and strong reduction of the subapical median seta on abdominal legs II and III.…”

“…A 658 bp fragment of the COI gene (DNA barcode) as well as 1,541 bp of the 18S rRNA and 971 bp of the 28S rDNA D1-D2 were amplified and sequenced from a specimen collected in the USA. To complete the COI data sets previously published (Shrubovych et al , 2014b(Shrubovych et al , 2014c, other Acerentulus and Andinentulus species were amplified for 18S rRNA: Acerentulus charrieri Shrubovych, Schneider & D'Haese, 2012, A. noeli Shrubovych, Schneider & D'Haese, 2014., A. pyreneicus Shrubovych, Schneider & D'Haese, 2014, and Andinentulus rapoporti (Condé, 1963; 28S rDNA D1-D2: A. noeli and Andinentulus rapoporti (2 different specimens); 28S rDNA D3-D6: A. charrieri (2 different specimens), A. noeli (2 different specimens), A. pyreneicus, and Andinentulus rapoporti. The sequences were deposited in BOLD under accession numbers ABPE002-17-ABPE011-17 (see Table 1).…”
