Kontschan, Jeno & Ermilov, Sergey G., 2023, Remarks on the genus Phymatodiscus Berlese, 1917, with the description of Phymatodiscidae fam. nov. and Bardizon eotvosi gen. nov., sp. nov. from Indonesia (Acari, Mesostigmata), ZooKeys 1182, pp. 223-235 : 223

Genus Phymatodiscus Berlese, 1917

Discopoma (Phymatodiscus) Berlese, 1917: 12.

Type species.

Discopoma miranda Berlese, 1905: 159, by original designation.

Diagnosis.

Phymatodiscid species lacking a pair of eye-like dorsal depressions. Margins of idiosoma with or without many prolongations.

List of the known species

Remarks. One species, Phymatodiscus titanicus (Berlese, 1905), is transferred here from the family Phymatodiscidae to the family Trachyuropodidae Berlese, 1917. According to the dorsal characteristics (only these were illustrated by Berlese 1905: fig. 13), our opinion is that this species belongs to the genus Bostocktrachys , as B. titanicus (Berlese, 1905) comb. nov., given that Berlese’s species has strongly sclerotized idiosoma and a deep transversal furrow on the dorsal shield ( Kontschán and Ermilov 2023c).
