SUPPLEMENTARY DESCRIPTION OF ADULT FEMALE (Figure 25).—Carapace elongate (Figure 25a.

Infold (Figure 25b): Posterior infold with 5 small processes between list and valve edge.

Size: USNM 151394, left valve, length 2.66 mm, height 1.21 mm, height 45.5 percent of length.

First Antenna: Base of proximal of the long terminal filaments of sensory bristle of 5th joint at point slightly past base of c-bristle of 7th joint (Figure 25c).

Second Antenna: Protopodite with medial spines near dorsal margin and 1 minute, distal medial bristle. Exopodite: bristle of 2nd joint reaching 9th joint, with ventral spines; natatory bristles of joints 3–8 with few, faint, proximal, ventral spines; joints 4–8 with small basal spines; 9th joint with lateral spine about length of 9th joint; joints 2–8 with small, faint spines forming row along distal margins.

Mandible: 2nd endopodial joint: dorsal margin with spinous a-, b-, c-, and d-bristles, 3 small proximal spines (2 of these with bases on medial surface), and 1 small spinous bristle proximal to a-bristle; lateral surface with long bristle between c- and d-bristles; medial side near dorsal margin with 1 short cleaning bristle between a- and b-bristles, 1 cleaning bristle between b- and c-bristles, 6 cleaning bristles forming oblique row near base of c-bristle, and 1 long spinous bristle just distal to base of d-bristle.

Maxilla: Endite I with 3 long spinous bristles and 1 short slender bristle. Basale: medial surface near dorsal margin with 1 proximal bristle and 1 midbristle; ventral margin with 1 proximal bristle, 1 minute distal bristle, and 1 long, spinous, terminal bristle; lateral surface with 1 proximal bristle.

Lateral Eye: Each with 8 large divided, amber ommatidia.
