Figure 1. (A-H) Photomicrograph (SEM) of grooming leg, Megalobrachium pacificum Gore & Abele, 1974, female (MZUSP 33040). (A) Left P5, ventral view. (B) Simple setae on distomesial surface of coxa. (C) Pappose setae on distolateral surface of basis-ischium. (D) Pappose setae on lateral surface of merus. (E) Straight serrate setae on distal surface of carpus, ventral view. (F) Detail of the straight serrate setae on distal surface of carpus. (G) Sickle-shaped serrate setae on distoventral surface of dactylus. (H) Tooth-like cuspidate setae and club-shaped setae on distal margin of dactylus (chelae). Cx = coxa; BI = basis-ischium; M = merus; C = carpus; P = propodus; D = dactylus; CS = club-shaped setae; Pp = pappose setae; S0 = simple setae; S1 = sickle-shaped serrate setae; SS = straight serrate setae; TC = tooth-like cuspidate setae; TP = terminal pore. Scale bars = (A) 0.3 mm; (B, C, E-H) 0.01 mm; (D) 0.1 mm.
