Material examined. Panama [Pacific]: 2 males, cl 4.9, cw 5.0 and cl 3.8, cw 3.9 ( MZUSP 33142 View Materials ), Río Mar , rocksand intertidal at low tide, in rock crevices, leg. A. Anker & J.F. Lazarus-Agudelo, 20.03.2015 .

Previous records from Panama. Gore (1982).

Distribution. East Pacific: Mexico, El Salvador, Panama (vicinity of Ciudad de Panamá, Río Mar), Colombia and Ecuador ( Haig 1960; Gore 1982; Hiller et al. 2004; present study).

Ecology. Rock-sand intertidal and shallow subtidal, known depth range: 0–9 m; typically under rocks and in rock crevices, but also in sponges and dead corals, among hydrozoans or inside (probably dead) bivalves ( Haig 1960; Gore 1982; Hiller et al. 2004).

Remarks. Megalobrachium festae (often spelled as M. festai , see Osawa & McLaughlin 2010 for discussion) is morphologically very similar to its western Atlantic sister species M. roseum ( Rathbun, 1900) (Hiller & Lessios 2019) , especially in the structure and ornamentation of the P1–P4. However, in M. festae ( Fig. 6 View FIGURE 6 ), the carapace is subtriangular and with larger tubercles; the P2–P4 are more robust; and the telson possesses five plates vs. seven in M. roseum ( Haig 1960) .
