Genus-level revision of the Heterozerconoidea (Parasitiformes: Mesostigmata) Author Klompen, Hans klompen.1@osu.edu Author Gerdeman, Beverly S. klompen.1@osu.edu text Zootaxa 2023 2023-07-28 5322 1 1 66 http://dx.doi.org/10.11646/zootaxa.5322.1.1 journal article 10.11646/zootaxa.5322.1.1 1175-5326 8203657 DD295EE6-AB3F-4377-900E-CC76F1C6BC2D Heterozerconoidea Diagnosis: Movable digit in adults with thin, strap-like dorsal extension (2); gnathotectum without prominent points (15); median dorsal setae minute (31); genitiventral and anal shields not fused (66, reversed within some Heterozerconidae ); some marginal opisthosomal setae flattened (77.2); acrotarsus on legs I present (82); setae av4 and pv4 on tarsi IV absent (101). Remarks: As noted in the character discussion, possession of opisthogastral suckers (63) is not assumed to be an apomorphy for this grouping, as homology of the discozerconid and the heterozerconid suckers is uncertain.
