Possibly the second ever finding of Robertus alpinus
Pedipalp denticle row comparison between Hadogenes, Opisthacanthus and Cheloctonus.
Hadogenes: random denticle arrangement with at least two rows distinguishable distally.
Opisthacanthus: two rows, each row with several enlarged denticles that evenly separate their subordinate row.
Cheloctonus: one row, evenly separated by several enlarged denticles which are flanked with moderately enlarged denticles on the inner side.
