GENITALIA: External, interal pockets absent; anterior receptaculum with two long anterior apodemes, three membranous chambers at base, those at sides with strongly sclerotized walls, lumen well developed; posterior receptaculum absent, posterior apodeme formed by entire plate (figs. 195B, E–G, 197D).
