Etymology.
The specific name is derived from the Latin word ovoideus, referring to the ovoid terminal apophysis of the male palp; adjective.
Diagnosis.
This species can be easily recognised by the palp (Fig. 13C-F View Figure 13 ) with the clavate retrolateral tegular apophysis (vs. absent, triangular, finger-shaped, or otherwise) and the ovoid membranous fan-shaped distal tegular apophysis (Fig. 13D, E View Figure 13 ) (vs. absent, ovoid, triangular, finger-shaped, or otherwise). Females are distinguished by the epigyne (Fig. 14C, D View Figure 14 ) with a weakly sclerotised transversal margin (vs. absent, M-shaped, arc-shaped, or otherwise), the funnel-shaped median septum (vs. rectangular, triangular, others), and the touching globular spermathecae (vs. widely or slightly separated).

MOA 0.25 long, front width 0.23, back width 0.29. Chelicerae (Fig. 13A, B View Figure 13 ) with three promarginal (middle largest, distal smallest) and six retromarginal teeth (distal largest, proximal smallest).

Palp (Fig. 13C-F View Figure 13 ). Femoral apophysis well-developed, width longer than half of length. Patella unmodified. Retrolateral tibial apophysis large, bending inward to the base of cymbium, triangular extruding in proximal part in retrolateral view, with a clear apophyses located at the base and a blunt apex in dorsal view. Sperm duct C-shaped, strongly sclerotised, around the base of retrolateral tegular apophysis, distal tegular apophysis and embolus; distal tegular apophysis club-shaped, longer than embolus. Conductor, ovoid, slightly shorter than embolus. Embolus, with proper broad base and a short, curved tip.

Epigyne (Fig. 14C, D View Figure 14 ). Epigynal plate bow-shaped, antero-medially with pair of concaved copulatory openings, with a funnel-shaped median septum, copulatory ducts, glandular appendage, connecting tubes and spermathecae distinctly visible through integument in intact epigyne. Anterior fovea separated by weakly sclerotised transversal margin. Copulatory ducts broad, located between copulatory openings and glandular appendages, posteriorly with pair of large, oval, transparent bursae. Glandular appendages short, partly covered by bursae, located on the anterior of connecting tubes.
