title: TABLE 3 in Deciphering a Chilean harvestmen enigma: what is Parabalta bicornis (Gervais, 1849) comb. nov. (Opiliones: Gonyleptidae: Pachylinae)

description: TABLE 3. Match (+M) or mismatch (–m) between fig. 10 (Gervais 1854), and Gervais’ (1849) description of G. bicornis and redescription of G. planiceps; features observable on fig. 4b (lateral view) are inserted in round brackets. Stronger evidence is marked as **.
