Previous records from Panama. Haig (1957, 1960); Gore & Abele (1976).

Distribution. East Pacific: Mexico, Costa Rica, Panama (Coiba Is., Secas Is., Bahía Honda in Veraguas, Las Perlas Is.), Colombia and Ecuador (Galápagos) ( Haig 1960; Gore & Abele 1976; García-Madrigal & Andréu- Sánchez 2009; present study).

Ecology. Intertidal and shallow subtidal, known depth range: 0–12 m; on rocky intertidal reefs and adjacent hard-bottom subtidal habitats rich in boulders, coral rubble and dead coral heads; under rocks or in crevices of rocks and dead corals, often found in interstices of living corals, such as Pocillopora and Pavona ( Haig 1960, 1968; Werding & Haig 1982; Hickman & Zimmerman 2000; García-Madrigal & Andréu-Sánchez 2007; present study).

Remarks. Petrolisthes glasselli is the eastern Pacific sister of the western Atlantic P. rosariensis Werding, 1978 ( Hiller et al. 2006). The two species share many morphological characters, such as the presence of two epibranchial teeth; the P2–P4 dactyli with a row of four spines ventrally; and the absence of pubescence on the ventral side of the P1 palm ( Hiller et al. 2006). However, P. rosariensis can be distinguished from P. glasselli by the convex lateral margin of the P1 palm (manus) and typically four instead of five teeth on the P1 carpus (Werding, 1982). Remarkably, despite their phylogenetic proximity, P. glasselli and P. rosariensis have very different colour patterns (cf. Figs. 51–53 View FIGURE 51 View FIGURE 52 View FIGURE 53 , 72 View FIGURE 72 ). The colour pattern of P. glasselli is in fact highly diagnostic among the eastern Pacific porcelain crabs, despite some variation observed in the Panamanian material ( Figs. 51–53 View FIGURE 51 View FIGURE 52 View FIGURE 53 ). The ventral side of most specimens is brightly coloured with deep carmin or wine-red ( Figs. 51 View FIGURE 51 , 52 View FIGURE 52 ), although at least in one male, the red colour is much less conspicuous, also on the dorsal side ( Fig. 53 View FIGURE 53 ).
