Sánchez-Ruiz, Alexander, Santos, Gabriel De Los, Brescovit, Antonio D. & Bonaldo, Alexandre B., 2020, The genus Syspira Simon, 1895 (Araneae: Miturgidae) from Hispaniola, with the description of four new species, Zootaxa 4894 (3), pp. 413-431 : 414

Genus Syspira Simon, 1895

Diagnosis. Spiders of the genus Syspira are easily recognized by the combined presence of a filiform embolus inserted retrolaterally ( Fig. 1A, C ), circling the bulbus proximally ( Fig. 2B ) and female epigynum with a pair of wide contiguous posterior ventral plates ( Figs 1D , 7D ) delimiting a small anterior atrium ( Fig. 1E ). Apart the presence of well developed epigynal posterior plates in females, males differ from those of Teminius Keyserling (the only other miturgid genus known to occur in the Caribbean) by the shape and position of the median apophysis, which is much more elaborated and inserted proximally in the retro-ventral tegular surface ( Fig. 1A – C ), as opposed to inserted distally in the pro-ventral tegular surface ( Platnick & Shadab 1989: figs 1, 5, 9)

Distribution. Southern United States, Mexico and Dominican Republic.
