Galapagetula Reygel, Willems & Artois, 2011

Emended diagnosis of Galapagetula (after Reygel et al. 2011). Koinocystididae with proboscis of the typical koinocystidid construction without proboscis juncture sphincter. Testes lie at mid-body or more caudally. Copulatory organ pear shaped, distal part cylindrical, containing an unarmed or armed cirrus. Female duct widened proximally, functioning as a seminal receptacle, only surrounded with muscles in its tube-shaped distal part. Two bursae open separately into the female atrium, a muscular one (accessory bursa) and a resorptive one.

Emended diagnosis of Galapagetula annikae (after Reygel et al. 2011). Species of Galapagetula without a mouth sphincter. Copulatory organ of the conjucta duplex-type, with a folded cirrus, armed with small spines. Female duct distally highly muscular with strong sphincter. Bursae without sphincters. Common gonopore at 85%.
