Witaliński, Wojciech, 2017, Key to the world species of Holoparasitus Oudemans, 1936 (Acari: Parasitiformes: Parasitidae), Zootaxa 4277 (3), pp. 301-351 : 306

Holoparasitus inornatus species-group (newly formed and defined)

Diagnosis. Both sexes. Gnathotectum trispinate; gland pores gv 2 in unmodified cuticle

Female. Presternal plate wide, narrowed medially, with a smooth anterior margin, lateral platelets free and narrow; sternum divided axially into two parts, left and right; posterior paragynial lobes distant; posterolateral protrusions locking the epigynial plate minute or absent; the thickening of the anterior paragynial edge facing coxa III absent; epigynium with the thickened antero- and posterolateral margins, the central prong short and rightangled, epigynial subapical structure not discernible; endogynium cup-shaped.

Male. Sternum without excipulum; the central part of hypostome regularly triangular and moderately sclerotised; hypostomatic setae not on a separate piece of cuticle; corniculi indented; fixed digit of chelicera slender, with many tiny denticles followed by a lamellar edge proximally, movable digit with several teeth in the distal half; leg II femoral main spur and axillary process short and similar in appearance.

Included species:

1. H. inornatus ( Berlese, 1906)

2. H. megacalcaratus Schmölzer, 1995

H. megacalcaratus Schmölzer, 1995 had been allocated to the Holoparasitus inornatus species-group due to a distinctly characteristic sternum in the female, which is split axially. The male, however, is so superficially described and illustrated that any conclusions drawn on its characteristics would be rather speculative. Furthermore, the second leg is spurred in the manner never found in any Holoparasitus species, and therefore still requires confirmation (see also Remarks).
