Two new species of Australian Eutarsopolipus (Acariformes: Podapolipidae) from Nurus medius (Coleoptera: Carabidae)

Abstract

Eutarsopolipus burwelli sp. nov. and E. echinatus sp. nov. (Acari: Podapolipidae) are described from Nurus medius Darlington, 1961 (Coleoptera: Carabidae), a large burrowing carabid beetle found in the rainforests of coastal central Queensland, Australia. Eutarsopolipus burwelli belongs to the ochoai species group, which is herein refined, and E. echinatus is placed tentatively in the pterostichi species group. A revised key to the species groups of Eutarsopolipus is provided. The synhospitalic species of Eutarsopolipus are reviewed and synhospitality within the genus is discussed.

Sheltered life beneath elytra: three new species of Eutarsopolipus (Acari, Heterostigmatina, Podapolipidae) parasitizing Australian ground beetles

“…Host beetles were all identified with the help of Geoff Monteith. Species group: pterostichi -Key characters of the group based on adult female: stigmata and tracheae absent; genua II-III without setae [42]. Type locality: Loc.…”

“…1a-1b). Length 68 (72-86), width 58 (60-68); cheliceral stylets length 66 (63-68); pharynx length 14 (15)(16)(17)(18), pharynx width 13 (13)(14); ch 19 (21)(22)(23)(24)(25)(26), su 3 (4)(5); distance between setae ch-ch 34 (40)(41)(42), su-su 17 (19)(20)(21)(22).…”

“…Australia is anticipated to harbour rich Eutarsopolipus fauna given its large diversity of carabid beetles [5]. This is inferred from small sampling efforts that have recently been conducted in some regions, and yet that discovered a considerable number of new species [31,[41][42][43][44]. Here, we describe three new species of Eutarsopolipus belonging to three different species groups (leytei, myzus, pterostichi) from three native Australian carabid beetles, raising the total number of Australian Eutarsopolipus to 30 species.…”

Tiny hitchhikers and parasites: a review of Australian heterostigmatic mites (Acari: Prostigmata) associated with insects, with description of three new species

“…It has a complete tracheal system, idiosomal plates, prominent ambulacral claws II-III, tarsus II solenidion and the largest number of femur I and genu I-III setae. Interestingly, the presence of ambulacral claws II-III is uniformly shared among almost all known Australian species except for E. echinatus which belongs to the pterostichi group (Seeman 2019a). Although all members of the pterostichi group uniformly lack a tracheal system and genu II-III setae, due to the inconsistency of ambulacral claws and leg setation, the current systematic status of this group is not well resolved.…”
