Callobius theoblicki Bosmans, 2021: 879, 32-41 (♂♀). Diagnosis. See Bosmans 2021 and diagnosis of C. lodovicii + sp. nov. Description. See Bosmans 2021 . Distribution. Portugal. Habitat. Litter of Pinus and Quercus forests at low and middle mountain range (from 160 to 890 m, see Bosmans 2021 ) Remarks. Cybaeopsis theoblicki shows the typical morphological characters of Cybaeopsis , in particular: a retrolateral tibial apophysis ending bifurcated, three dorsal apophyses in the male palpal tibia two of which elongated and sharp, epigyne lacking a median lobe, and lateral lobes of epigyne extended laterally with a flat posterior margin. All these characters can be easily observed in the photos illustrated in Bosmans (2021) . The size range reported for the species (3.8-4.5 mm) further supports its affinity with the genus Cybaeopsis rather than Callobius . Based on these characters, the transfer of C. theoblicki to the genus Cybaeopsis is herein proposed.
