Figure 5 in Chaetotaxy and setal diversity of grooming legs in species of porcelain crabs (Crustacea: Anomura: Porcellanidae)

Figure 5. (A-F) Photomicrograph (SEM) of grooming leg, Petrolisthes tuberculatus (Guérin, 1835), male (MZUSP 25888). (A) Left P5, ventral view. (B) Distal surface of propodus and dactylus, lateral view. (C) Propodus and dactylus, lateral view. (D) Sickle-shaped serrate setae on distal surface of propodus. (E) Dactylus and distal third of propodus, lateral view. (F) Tooth-like cuspidate and club-shaped setae on distal margin of propodus. (G, H) Photomicrograph (SEM) of grooming leg, Pisidia longicornis (Linnaeus, 1767), male (MZUSP 18730). (G, H) Photomicrograph (SEM) of grooming leg, Pisidia longicornis (Linnaeus, 1767), male (MZUSP 18730). (G) Left P5, ventral view (arrow indicates the hinged articulation and the extensive area of arthrodial membrane between merus and carpus). (H) Tooth-like cuspidate setae on distal margin of dactylus. Note in B scattered club-shaped setae on the closing surface of dactylus, and in F tooth-like cuspidate setae furnished with a strong, single median spine. 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, G) 0.3 mm; (B, H) 0.005 mm; (C, E) 0.1 mm; (D, F) 0.01 mm.
