Fig. 3A–D

Material examined

PANAMA • 5 whole mounts; Pacific Ocean , Isla Iguana; 7°37′46″ N, 79°59′49″ W; depth 6 m; 6 Mar. 2016; subtidal, coarse sand; HU XIX.2.01–XIX.2.05 • 2 whole mounts; same collection data as preceding; 7°38′06″ N, 79°59′48″ W; depth 10 m; subtidal, coarse sand mixed with small rocks and covered with organic matter; HU XIX.2.06–XIX.2.07 .

Distribution

Bahia Academy, Santa Cruz, Galapagos Islands ( Artois & Schockaert, 2000).

Remarks

The specimens collected in Panama are morphologically similar to those from the Galapagos. The prostatic stylet type III ( Fig. 3A–D ) is 46–76 µm long (x = 62 µm; n = 7) and 10–31 µm wide (x = 21 µm; n = 7). A feature of the female system, not mentioned by Artois & Schockaert (2000), is the presence of a proximal, apparently sclerotised cap in the seminal receptacle.
