Castianeira monai Pett, 2023: 936, figs 1–8

( holotype ♂ from PARAGUAY: Ñeembucú department, Desmochados, Estancia Cabaña Santa Elisa II, 22.VI.2020, B.L. Pett & V. Vladimirova leg. (CIPLT-Ar 692(1), examined ).

Remarks. Castianeira monai belongs to Grismadox due to the following combination of characteristics: presence of recurved PER, spiniform AS II, anterolaterally fused dorsal and epigastric scutum, and branched RTA with dRTA and vRTA, the latter only slightly conspicuous (Fig. 8A–D; Pett 2023: figs 1–3).

Diagnosis. Grismadox monai comb. nov. resembles G. baueri by the orange body color, but can distinguished by the lateral margins of the carapace with dark bands, the embolus with six keels and an embolic extension between them (vs. dark bands absent, five keels, and lacking an embolic extension in G. baueri) (cf. Fig. 8A–D; Pett et al. (2022): figs 12–15).
