Kincaidiana Altman, 1936

Emended diagnosis (modified from Cook [1971]). Medium-sized to large worms with long, pseudosegmented proboscis ( Figs. 1A, 2A–B). Chaetae bifid and enlarged in a few anterior segments ( Fig. 1B); simple-pointed posteriorly. No distinct pharyngeal pad ( Fig. 2D). One or two pairs of lateral blood vessels, with many blind branches, in posterior segments ( Fig. 1C). Nephridia begin on 11/12; postseptal expansion narrow and directed dorsally ( Fig. 1D). One pair of testes in IX, one pair of ovaries in X. Male pores on IX, near 9/10, usually paired and slightly inside chaetal lines ( Fig. 1A). Pendant penes within shallow sacs when retracted; everted sacs form low porophores ( Figs. 2G–H). Atria club-shaped to elongate-cylindrical, ental ¾ or more loosely covered with multicellular, pyriform prostate glands ( Figs. 1E, 2G). One pair of male funnels, usually extending back one or more segments in sperm sac ( Fig. 1E). Vasa deferentia do not penetrate posterior septum (9/10); they join atria near-medially; muscle coat of atria extends for a short distance along vasa deferentia ( Fig. 2I–J). Female pores on chaetal lines at posterior septum of first post-atrial segment. Three pairs of spermathecae, in IX, X, and XI; pores slightly inside ventral chaetal lines, usually in line with or slightly anterior to chaetae ( Fig. 1A). Spermathecae with an elongate, thick duct and an elongate-tubular to elongate-pyriform ampulla ( Figs. 1E, 2E–F).
