( Fig. 110a–e, h View FIGURE 110 . Map 68)

Material: Victoria: holotype ♂, Brooms Rd , 7.5 km NE of Yambuna 36°06'S, 145°05'E, pitfall traps, 17–22 Jan 1994, G.Milledge, MV K4403 . Paratype GoogleMaps : Victoria: allotype 1♀, 36°09'S, 145°01'E, State Forest , 1 km SE of Yambuna, pitfall traps, 17–22 Jan 1994, G. Milledge, MV K6985 GoogleMaps .

Diagnosis. Males are unique in the genus in the very long terminal extent of the embolus ( Fig. 110a View FIGURE 110 ). Females are unusual amongst the P. janthina species group in having only two pairs of spines on ventral tibiae I and II.

Etymology. The species epithet is a noun in apposition from the type locality.
