Diagnosis. Globular sponge, ranging in size from 3 x 3 x 1.5 cm to 13 x 13 cm in diameter with raised cylindricalshaped oscules and numerous large thin inverted mammiform areolate porefields ( Fig. 8C). Styles are terminally spined, 435 (400–464) x 16 (16) m, n=20 ( Fig. 8N). Microscleres ( Fig. 1S): anisodiscorhabds, stout and squat with the median whorl just above the manubrium. The median whorl is slightly smaller in diameter than the subsidiary whorl. Both are deeply notched along the rim and divided into four segments, each possessing denticulate margins of 2–4 spines that are themselves microspined. Anisodiscorhabd length, 40 (35–44) x 7 (7) m, n=20. The choanosomal skeleton is a firm, dense, well developed but irregular polygonal reticulation ( Fig. 9A View FIGURE 9 ), with tracts ranging in width from 273–455 m in thickness. The sponge, whose habitat is sandy gravel at 127–202 m depth, has only been recorded from Kurile Island, Sea of Okhotsk, Russia ( Fig. 7 View FIGURE 7 ) (from Samaai and Krasokhin 2002).
Remarks. Latrunculia oparinae is the only species in this genus that possesses terminally spined styles, making it unique among the species previously described within Latrunculia . The anisodiscorhabds are also unique in their short squat morphology.
