Type material. Holotype: female, PAPUA NEW GUINEA: New Britain: Nakanai Mts., near Camp 3, Tompoi , 5.343° S, 151.315° E, elev. 1590 m, 20 April 2009, coll. D. Gassmann & K. Sagatasame ( UBC-SEM AR00114 ).

Etymology. The specific epithet is a patronym in honor of Dr. J. Prószyṅski, who has made great contributions to the study of jumping spider systematics and biodiversity.

Diagnosis. Resembles Xenocytaea triramosa Berry, Beatty & Prószyṅski, 1998 and X. stanislawi Patoleta, 2011 in lacking the posterior pocket of the epigynum, but differs in the spermatheca closer to the epigynal groove and the shape of the anterior arch of the epigynum ( Figs 304–305). Also similar in epigynal shape to X. zabakai Berry, Beatty & Prószyṅski, 1998 , but can be distinguished by the spherical spermatheca ( Fig. 305).

Description. Female (holotype, UBC-SEM AR00114). Carapace length 1.6; abdomen length 1.7. Chelicera: red brown; with two promarginal teeth and one unident retromarginal tooth. Epigynum ( Figs 304–305): with a convex arch anteriorly; opening to copulatory duct at posterior end of the arch. Copulatory duct relatively short, without accessory gland; spermatheca spherical. First pair of legs with three pairs of ventral macrosetae on tibia. Measurements of legs: I 2.9, II 2.8, III 3.7, IV 3.8. Color in alcohol ( Fig. 303): carapace dark red brown, with some white scales; abdomen light yellow with brown to brownish markings; venter with two brownish stripes behind genital groove; legs light yellow.
