616Zoological Studies 50(5): 611-635 (2011)1 aesthetasc, and 8 + 1 aesthetasc. Parabasalprocess absent. Antenna (Fig. 3G) 2-segmented;corpus about twice as long as claw, former bearing1 broad basal seta on medial surface; claw bearingsimilar basal seta and terminal striations. Mandible(Fig. 3H) and maxillule (Fig. 3I) essentiallyas in previous species. Maxilla (Fig. 4A, B)2-segmented; lacertus unarmed; brachium bearing1 subterminal seta on medial margin, 1 blunt,terminal element, and large patch of denticles onouter surface; terminal claw fringed with rows ofdenticles along both edges. Maxilliped (Fig. 4C)2-segmented; corpus with fine denticles scatteredin myxal region; shaft longer than claw, with 1subterminal seta on medial margin; claw withstriations as in antenna.Ventral surface of leg 1 (Fig. 4D) with denticlesscattered on protopod and endopod;outer protopodal seta simple and thin, but innerprotopodal seta spiniform and arising from largepapilla; exopod 1-segmented and large, tipped with5 robust spines, inner 2 of which bear denticles onboth sides; endopod smaller than exopod, carrying1 long seta terminally. Leg 2 (Fig. 4E) protopodinconspicuous, without inner and outer setae;exopod armed as in leg 1, but seta on endopodbilaterally denticulate. Leg 3 with lamelliform ramicompletely fused to form a long plate completelycovering urosome ventrally (Fig. 3B) and leavinglarge gap dorsally (Fig. 3A); posterior edge ofventral lamella with 3 indentations (Fig. 3B). Leg 4a pair of long bilobate processes (Fig. 3A) arising(A)(B)(D)(C)(E)Fig. 4. Lernanthropodes trachinoti Pillai, 1962, female.
