Genus Eutarsopolipus Berlese, 1913

Type species: Tarsopolipus lagenaeformis Berlese, 1911, by original designation.

Diagnosis. See Seeman (2019a).

Remarks. Eutarsopolipus is morphologically diverse, reflecting its diversity as the largest genus of Podapolipidae (Tables 1–4). Males in this genus are distinctive due to the terminal position of their genitalia, which is shared only by Archipolipus, Ovacarus and some exceptional species of Chrysomelobia (Table 1). The genus is difficult to define based on females and larvae alone, appearing similar to five other genera with three pairs of well developed legs (Tables 1–3). Generally, the femoral and genual setation (in combination) in the female and larval female define Eutarsopolipus species, but this setation is very similar to its possible sister-group genera Dorsipes and Ovacarus, both found on Carabidae (Husband 1991) . Dorsipes is very close to Eutarsopolipus and is likely to be its sister group: it would not be surprising to find species that form a grade into Eutarsopolipus, further blurring lines between the genera. Most Dorsipes species have a more complete leg chaetotaxy, with femora I–III 3-(0-1)-(0-1) and genua I–III (1-4)-(0-3)-(0-3). The presence of various femoral and genual setae, which are never found in Eutarsopolipus, will indicate the mite belongs to Dorsipes . For instance, Dorsipes mackenzyae Husband & Husband, 2007 has a much-reduced genual setation for genua I–III (1-0-0), similar to many Eutarsopolipus, but retains seta d on femora II–III, which is never found in Eutarsopolipus . Similarly, Dorsipes auncinius Husband, 2000c has a reduced femoral setation (3-0-0) but the retention of two setae on genu II has never been found in Eutarsopolipus .
