Abasia inflata

MATERIAL EXAMINED.—Holotype (USNM 171328) and 3 paratype (USNM 171329) from the gills of Saurida gracilis from the Philippines. One from the Philippines. One from Trobriand Islands, New Guinea. One from New Georgia, Solomons Islands. Four from Ambon and Kabaena Islands, Molluccas. All other material from the gills of the same host species as the types.

Female: Body form as in Figure 32a–c. Total length 2.25 mm, greatest width 0.96 mm. Cephalon slightly longer than wide (0.90 × 0.73 mm), dorsal surface papillose (Figures 39f, 40a). Genital segment about as long as wide (0.88 × 0.90 mm), wider than cephalon. Abdomen 2–segmented; first segment inflated with other posterior corners produced, extending to or slightly beyond caudal rami, about as wide as genital segment; second segment (Figure 32d) much smaller. Caudal rami (see Figure 32d), wider than long (47 × 35 μm), with 6 plumose setae (longest 94 μm).

Rostrum (Figure 32e) with 2 fleshy lobes projecting beyond first antennae. Frontal lunules absent (not seen with light or scanning electron microscope). Mid-ventral rugose area (Figures 40b,c) present as in previous species. First antenna (Figure 32f) of usual caligoid type; basal segment relatively smaller than in preceeding species, no asthetes seen. Second antenna (Figure 32g) uncinate, claw more curved than in proceeding species. Mouth tube with mandible and strigil (see Kabata, 1974:1587) within (Figure 40d). Mandible (Figure 32h) as in other species of the genus. First maxilla (Figure 32i) simple, with tip bearing 3 setae, one very broad, with spinules on distal half. Second maxilla (Figure 32j) with short distal claw (Figure 40e) bearing rows of spinules, an inner distal spinulose spine, and a palmate process (Figure 40f) on outer edge near base of distal claw. Maxilliped (Figure 32k) as in preceeding species.

Leg 1 (Figure 33a) weakly developed; exopod 1–segmented, bearing a lateral outer spine where segmentation occurs in other species, 4 short terminal setae, armed as in the figure; endopod small, bearing a short distal seta. Leg 2 (Figure 33b) with broad hyaline membranes as in previous species; exopod 2–segmented, first segment with well-developed outer distal spine and an inner seta, last segment with an outer well-developed spine, 2 weak outer spines and 4 terminal to inner plumose setae; endopod 2–segmented (segmentation weak), first segment with an inner plumose seta, last segment with 5 outer to inner plumose setae. Leg 3 (Figure 33c) reduced to a single segment bearing 1 subterminal spine and 2 short terminal spines, longest armed with rows of spinules. Legs 4–6 absent.

Male: Unknown.

ETYMOLOGY.—The Latin inflata (“swollen”) alludes to the 2 lobes on the rostrum.
