title: TABLE 2 in Deciphering a Chilean harvestmen enigma: what is Parabalta bicornis (Gervais, 1849) comb. nov. (Opiliones: Gonyleptidae: Pachylinae)

description: TABLE 2. Match (+M) or mismatch (–m) between the descriptions of G. asperatus (both Gervais 1847 and 1849) and G. bicornis. Features invoked by Pessoa-Silva et al. (2021) to support their synonymy proposal are underlined.
Gonyleptes asperatusmatchGonyleptes bicornisGranulation, DS1847: Back covered by abundant granular and spiny roughness. 1849: This species is remarkable for its abundant roughness, either spiny of simply granulous on its dorsal surface (…) granules arranged in series on the disc.–mdisco … vix granulato ‘Disc’ scarcely granular.Granulation, carapace and lateral areas1847: Scutum with serrate granules at the ocular region and the lateral border. 1849: lateraliter ad marginem granoso - many fine and dense small granules in the anteocular region and on the bilateral border–mcephalo-torace margine laterali vix granoso Lateral margins of cephalo-thorax scarcely granulous.Body, shape1847: Body triangular somewhat pyriform 1849: corpus ovato triangulare – Body triangular, rounded, somewhat lyriform on the cehalothorax.?Corpus ovato-lyratum Cephalo-thoracic ‘disc’ sub-lyriformOcular mound1847: Each eye at the external base of a straight and acute spine. 1849: cephalo-thorace ad oculos bispinigero+MIntra oculos spina duplice acuta Eyes on the external base of a double spine, imitating a pair of little straight and acute hornsArmature of DS and FT1847: Another pair of spines on the middle of the dorsal region. 1849: In medio tuberculis sparsis spinisque duabus rectis distincto – a pair of spines in middle of the dorsal region; other two pairs in the superior part of abdomen [free tergites]–mIt lacks gemiform tubercles on the dorsum, only some very weak on the posterior part [area V] and on the superior abdominal arcs [free tergites]DS, divisions1849: Disc with linear division little accentuated?Marked on the dorsal disc by transverse lines [no further detail]CxIV, armature1849: Ad angulos posticos lateraliter spina valida, apice inaequaliter biramosa – Coxae of hind legs end in a strong spine, split like the tip of a deer horn+MAd coxas spina postero-laterali subdivisa – Hind coxae end posteriorly in a incurved superior spine, inequally divided in twoTrIV, armature1849: The following article is not granous, but very spiny?The next article has a posterosuperior spine inclined inwardsFeIV. armature1849: Femoribus intus multispinosis, spinulis crassis, inaeqalibus – ‘Thigh’ granulous, a little distorted, with strong and unequal spines along its ‘external’ border [must be a mistake, fig. 9 shows they are on the internal border]?‘Thigh’ straight, granulous and multispinous: spines are unequal, the strongest one at its base.Ti IV, armature1849: Next article [patella] and leg [tibia] are also covered of granules [no special armature is mentioned]–m‘Leg’ [tibia] with three spines, one near the base and the other two close to the tarsal articulation
