Catalogue of snout mites (Acariformes: Bdellidae) of the world

Abstract

Bdellidae (Trombidiformes: Prostigmata) are moderate to large sized predatory mites that inhabit soil, leaves, leaf litter, and intertidal rocks. They are readily recognized by an elongated, snout-like gnathosoma and by elbowed pedipalps bearing two (one in Monotrichobdella Baker & Balock) long terminal setae. Despite being among the first mites ever described, with species described by Carl Linnaeus, the knowledge about bdellids has never been compiled into a taxonomic catalogue. Here we present a catalogue listing 278 valid species; for each species we include distribution information, taxonomic literature, and type depository institutions. The genus Rigibdella Tseng, 1978 is considered a junior synonym of Cyta von Heyden, 1826, and Bdellodes Oudemans, 1937 is considered a junior synonym of Odontoscirus Tohr, 1913. Illustrated keys to subfamilies and genera are presented, as well as keys to species of each genus.

Diversity and Distribution of Mites (Acari: Ixodida, Mesostigmata, Trombidiformes, Sarcoptiformes) in the Svalbard Archipelago

“…The arrangement of the Trombidiformes families follow [31] with the exception of the Eriophyidae that is included in the Endeostigmata, as suggested by [32,33]. Names and distributions of the Bdellidae follow [34]; Cunaxidae- [35]; Cocceupodidae and Eupodidae- [36,37] for nomenclature, and [38,39] for distributions; Penthaleidae- [40]; Penthalodidae- [41]; Rhagidiidae- [42][43][44]; Halacaridae- [45]; Triophtydeiidae- [46] for taxonomy, and [47,48] for distribution; Tydeidae- [49,50]; Iolinidae- [51,52] for taxonomy, and [47,53] for distributions; Sperchontidae- [48,54,55]; Trombidiidae- [56]; Syringophilidae- [57]; Stigmaeidae- [58]; Tetranychidae- [59,60]; and Pygmephoridae- [61].…”

Two new species of Bdellidae (Acari: Prostigmata) from China

“…Odontoscirus Thor, 1913 is the biggest genus of Bdellidae, currently comprises 100 species, including several species previously treated in the genera Bdellodes Oudemans, Hoploscirus Thor, Thoribdella Grandjean, Octobdellodes Atyeo and Biscirus Thor (Hernandes et al 2016; Paktinat-Saeej et al 2016; Barbar et al 2017; Porta et al 2020. The genus can be distinguished from other genera of the family mainly by subcapitulum with six pairs of ventral setae, trichobothrium present on tibiae II and each chelicera with at most two setae (Hernandes et al 2016).…”

Acari of Canada

“…Cunaxids and bdellids are predators in soil and litter, but also on plant surfaces (Walter et al 2009). In their recent catalogue, Hernandes et al (2016) list only seven species of Bdellidae from Canada. In contrast, Lindquist et al (1979) included 15 species, and we include 20 recorded species with an additional 25 species expected (Table 3).…”

“…Even for some of the better known acarine families in North America (e.g., Mesostigmata: Phytoseiidae; Prostigmata: Bdellidae, Tetranychidae, Trombiculidae), there are no species checklists available for Canada. There are large numbers of unpublished records for species present in Canada, but not reported in the world or North American catalogues (Denmark and Evans 2011, Walters et al 2011, Hernandes et al 2016, Demite et al 2018, Migeon and Dorkeld 2018).…”
