Tibia and patella dorsal view; D. Palp, retrolateral view. Additional Material Examined . None. Diagnosis . Goeldia chinipensis differs from other species by the tegular process finger-shaped, with base larger than the apex ( Fig. 8A ); by the thick and distally constricted patellar apophysis ( Fig.7B–C ) and torsion of the palpal tibia ( Fig. 8C ).
