Haplotaxoides sp. A

Figure 4. Haplotaxoides spp. from various sites. A, chaetae, Haplotaxoides decipiens from Guadalupe Creek, California, USA (non-type specimen): from left to right, dorsal and ventral chaetae in X, a mid-body segment, and a posterior segment. B, chaetae, Haplotaxoides spA from Smith River, California (specimen CE32193):dorsal and ventral chaetae from XX, and from a posterior segment (the ventral chaeta with a partially formed replacement). C–D, chaetae, Haplotaxoides tehama from Sacramento River, California:(C) from left, dorsal and ventral chaetae from segments XX and C (large, immature non-type worm); (D) dorsal and ventral chaetae from XXV, from a posterior segment, and genital chaetae from XIV and XVI (paratype). E, chaetae, Haplotaxoides spC from the Metolius River, Oregon, USA (not genetically analysed): dorsal and ventral chaetae from a mid-body segment and a posterior segment (ventrals have developing replacements). F, possible spermathecae in VI–VII, a partially mature Haplotaxoides decipiens from Los Gatos Creek, California (paratype). G, midventral glands and ventral nerve cord in VII–VIII, an immature Haplotaxoides decipiens from Guadalupe Creek (non-type). H, nephridium in XLIV, Haplotaxoides decipiens from Los Gatos Creek. I–K, Haplotaxoides tehama, from Sacramento River (paratype): (I) anterior end; (J) reproductive segments (XI–XVIII), ventrolateral view, ventral glands and chaeta greatly enlarged in XVI; (K) a lateral view of XIII.L, reproductive segments (XII– XVI) from a nearly mature Haplotaxoides tehama, Sacramento River (paratype), ventral view, ovaries and female funnels obscured by gut contents, ventral glands enlarged in XVI.
