Figure 4. (A, B) Photomicrograph (SEM) of grooming leg, Pachycheles grossimanus (Guérin, 1835), male (MZUSP 26392). (A) Distal margin of propodus and dactylus, frontal view showing tooth-like cuspidate and club-shaped setae. (B) Detail of tooth-like cuspidate and club-shaped setae on distal margin of propodus. (C-H) Photomicrograph (SEM) of grooming leg, Petrolisthes armatus (Gibbes, 1850), male (MZUSP 24562). (C) Left P5, ventral view. (D) Straight serrate setae on distal surface of carpus. (E) Detail of the straight serrate setae on distal surface of carpus. (F) Dactylus and propodus, lateral view. (G) Tooth-like cuspidate and club-shaped setae on distal margin of dactylus. (H) Detail of tooth-like cuspidate setae on distal margin of dactylus. 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 = toothlike cuspidate setae. Scale bars = (A, B, G) 0.01 mm; (C) 0.3 mm; (D, F) 0.1 mm; (E, H) 0.005 mm.
