TABLE 4 in Deciphering a Chilean harvestmen enigma: what is Parabalta bicornis (Gervais, 1849) comb. nov. (Opiliones: Gonyleptidae: Pachylinae)

TABLE 4. Comparison of diagnostic characters between male Parabalta bicornis comb. nov. versus P. reedii (cf. PérezGonzález et al. 2022: fig. 2) and P. cristobalia (cf. Roewer 1943: pl. 2, figs. 14, 14 a).
Parabalta bicornisParabalta reedii / Parabalta cristobaliaCx IV: prolateral apophysisbifid, short, diagonally orientedsimple, curved tip, points backwardsTrIV: prolateral apophysissmall, ax-likebilobate, distal lobe is short and parallel to border (P. reedii) or large, finger-like, pointing sideways (P. cristobalia)TrIV: apical prodorsal finger-like apophysislarge, oriented upwards, inclined mediallyoriented sideways, either short (P. reedii), or long and parallel to the former apophysis (P. cristobalia)FeIV: prodorsal basal apophyses1–2, conic + acute granulesnoneFeIV: retrodorsal apophysislarge; followed by small apophyses of decreasing sizeeither large (P. reedii) or small (P. cristobalia), it is only followed by granulation on the medial sideFeIV: proventral row of tubercles / apophysesonly a row of tubercles, no subapical apophysisa large subapical apophysis pointing sideways, either alone or with 2–3 smaller ones in a rowPaIV: ventral acute apophysestwoone (P. reedii) or two (P. cristobalia)Ti IV: ventral acute apophysesone basal, three distal, a large gap in between (2–3 rudimentary tubercles may exist)one basal, three distal, in between one or two additional
