Figure 7 in Chaetotaxy and setal diversity of grooming legs in species of porcelain crabs (Crustacea: Anomura: Porcellanidae)

Figure 7. (A-C) Photomicrograph (SEM) of grooming leg, Porcellana platycheles (Pennant, 1777), male (MZUSP 16261). (A) Left P5, lateral view. (B) Dactylus and distal half of propodus, lateral view. (C) Tooth-like cuspidate setae on distal margin of dactylus and propodus. (D-H) Photomicrograph (SEM) of grooming leg, Porcellana sayana (Leach, 1820), male (MZUSP 28138). (D) Left P5, ventral view. (E) Dactylus and distal third of propodus, lateral view. (F) Distal surface of propodus and dactylus, frontal view. (G) Distal margin of propodus and dactylus, frontal view, with tooth-like cuspidate, club-shaped and simple setae. (H) Detail of tooth-like cuspidate setae and club-shaped setae on distal margin of propodus. Note in E distinct gap between fixed and movable fingers when chela is closed, and in H the tooth-like cuspidate setae provided with minute, unevenly sized, slightly acuminate teeth. 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. Scale bars = (A, D) 0.3 mm; (B, E, F) 0.1 mm; (C, G, H) 0.01 mm.
