Neopisosoma dohenyi Haig, 1960

Neopisosoma dohenyi Haig 1960: 128 , pl. 9, pl. 30, fig. 4; Werding & Haig 1982: 64; Lazarus-Agudelo & Cantera-Kintz 2007: 229; García-Madrigal & Andréu-Sánchez 2009: 28, fig. 4G.

Material examined. Panama [ Pacific ]: 1 ov. female, cl 5.2, cw 6.6 ( FLMNH UF 57124 ), Las Perlas Is ., Isla Saboga , rocky shore near “Beach Club”, 8°37’29.3”N, 79°04’13.6”W, rocky intertidal, in rock crevices, leg. P.P.G. Pachelle & M. Leray, 20.03.2019 (fcn PP 19-022) .

Previous records from Panama. Haig (1960).

Distribution. East Pacific: Mexico, Costa Rica, Panama (Las Perlas Is., Bahía Piña in Darién) and Colombia ( Haig 1960; Lazarus-Agudelo & Cantera-Kintz 2007; Miranda & Mantelatto 2016; present study).

Ecology. Rocky and mixed rock-sand intertidal and shallow subtidal, presently known depth range: 0–7 m; among algae, in corals and rocks, occasionally associated with (dead?) bivalves (García-Madrigal & Andréu- Sánchez 2009; present study).

Remarks. Neopisosoma dohenyi is presumably the eastern Pacific sister of the western Atlantic N. angustifrons . These two species share the presence of rough granules on the dorsal surface of P1, the absence of crests on the P1 carpus, the five-plated telson and the absence of pleopods in males. However, N. angustifrons presents two rows of enlarged granules near the outer (lateral) margin of the P1 palm and extending onto the pollex, which is not the case of N. dohenyi , whilst the P1 carpal teeth of N. angustifrons are less projecting than in N. dohenyi ( Haig 1960) .

Another eastern Pacific species of Neopisosoma , N. bicapillatum Haig, 1960 , ranging from Galápagos and mainland of Ecuador and Colombia to Costa Rica ( Haig 1960; Vargas & Cortés 2006; Lazarus-Agudelo & Cantera- Kintz 2007), is likely present in suitable habitats on the Pacific coast of Panama, especially on the more exposed rocky shores of Coiba and Las Perlas Is., but has not yet been collected there (see Table 2 and Fig. 87E ).
