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


The specimens collected in Panama are morphologically similar to those from the Galapagos. The prostatic stylet type III ( Fig. 3A–D View Fig ) 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.
