From “artzain”, shepherd in the Basque language. The species is named for the many Basques who migrated to Idaho to work as shepherds in remote valleys.</p> <p>Description (based on populations from the Big Lost River Basin, Idaho). Length of preserved worms 11–19 mm; 56–75 segments; diameter in X 0.4–0.7 mm. Prostomium with proboscis, the latter 240–530 µm long, about 65 µm diameter at middle (Fig. 1A). Segmentation distinct in anterior segments; anterior secondary annulus about ¼ segment width, beginning segment IV and extending throughout body length except for clitellum. Chaetae (Figs. 1B, 2A) with nodulus median to slightly distal (about 0.4–0.5 from distal end), similar in anterior and posterior segments; within each pair, the inner chaeta is slightly longer, with a more proximal nodulus; ventral chaetae in preclitellar segments 122–192 µm, shorter in II (102–115 µm); in middle and posterior segments 127–192 µm long; dorsal chaetae 122–175 µm in anterior segments, and 120–175 µm in postclitellar segments. One pair of male pores in X, midway between chaetae and posterior septum (Fig. 1A,E,F), on short papillae (ca. 30–40 μm long) within broad, concave, ring-shaped porophores (Figs. 1C,F, 2G); porophore width 94–134 µm, height 30–72 µm; in some unmated specimens the atrial duct opens in a simple pore without a porophore. Two pairs of simple spermathecal pores, well behind ventral chaetae, on or slightly lateral to the ventral chaetal lines in XI and XII (Fig. 1A,D); those in XII very close to the posterior septum (12/13). Female pores on 11/12.</p> <p>Epidermis 16–28 µm thick in anterior segments, longitudinal muscles 26–44 µm thick. Clitellum (IX) X to XII, up to 36 µm thick. Pharynx mostly in II–IV, without a prominent dorsal pad; pharyngeal glands in IV–VI (VII). First nephridium on 12/13, nephridial duct without vesicle at pore.</p> <p>Paired testes in IX and X, ovaries in XI. Sperm sacs extend anteriorly to VIII, posteriorly to XIII or XIV; egg sacs to XV. Male funnels on 9/10 and 10/11, of similar size. Free portion of both anterior and posterior vasa deferentia 14–25 µm wide and about 320–600 µm long. Posterior vas forms a short loop in XI before entering X; both join basal part of atrial ampulla, run along outer surface a short distance, then under the muscle layer to enter atrial lumen near midpoint of the ampulla (Figs. 1E,F, 2E). Atrium petiolate, entirely in X, total length 440–720 μm; atrial duct narrow (180–300 µm long, diameter 18–30 µm), gradually widening into the elongate ampulla, and widening slightly near the ectal pore (Figs. 1C,E,F, 2B). Atrial ampulla covered by a layer of prostate cells, 10–24 µm high; layer may appear continuous (Fig. 2D), or as small, tightly-packed multicellular clusters (Fig. 2C); maximum atrium diameter in ental part of ampulla 127–205 µm; epithelial cells cuboidal, not glandular, forming a narrow layer, 3–10 µm high; atrial musculature very thick in ampulla (14–42 µm); muscle fibers arranged in an irregular, somewhat diagonal direction in the median part of the ampulla (Fig. 2 D–F). Atrium length 4–7 times porophore width, and 0.7–1.5 times body diameter in X.</p> <p>Spermathecae paired in XI and XII (Fig. 1E,F), either both with sperm, or only the anterior pair well-developed and filled with sperm. Spermathecal ampullae may extend into adjacent segments; ducts usually in segments XI and XII, but the second pair may extend into XIII, due to the pore location near the posterior intersegment. Ampullae irregular, sac-like, with uniform epithelial layer not glandular, about 8 µm thick; sperm appears unordered within ampulla (Fig. 2H). Spermathecal ducts short and strongly tapered, 40–150 µm long, with gradual transition to ampulla; usually with columnar cells and a narrow lumen; muscle layer thin (ca. 1 µm) (Fig. 2I,J). Ectal pores of spermathecae without glands or distinct epidermal modification.</p> <p>Specimens from other drainages: Two specimens from sites in other drainages (1 each from Muldoon and Hayden Creeks, both within the Snake River catchment) are similar to typical specimens in diagnostic characters, with elongate (but somewhat shorter, 320–595 µm), petiolate atria, with thick muscle layer and thin prostate layer. Male porophores are broad and slightly concave.</p> <p>Remarks. Externally, E. artzaini n. sp. is distinguished from other Eremidrilus species by the low, concave (annular) porophore, which surrounds a small papilla terminating in the male pore. Atrial morphology differs from that of all other species in the following combination of characters: large dimensions (Table 2), petiolate form (with elongate, narrow duct), thick and complex muscular layer, very thin epithelium, and thin layer of prostate glands (see the descriptions and Fig. 11 below; see also Fig. 5 in Fend &amp; Rodriguez 2003). Spermathecal pores are close to the posterior septa, and approximately on the ventral chaetal lines, as in other species described here; in contrast, they tend to be more laterally positioned in species having one spermathecal segment (cf. Fig. 7 in Fend &amp; Rodriguez 2003). The posterior spermathecae (in XII) are usually smaller than the anterior pair (in XI), and may not contain sperm.</p> </div>	https://treatment.plazi.org/id/03D287B7A57AFFCAFF7D6C66F430FDD6	Public Domain	No known copyright restrictions apply.

Named for the great biologist and naturalist Alexander von Humboldt, who emphasized the relationships between species diversity and their distribution, forming the basis of biogeography, and inspiring many generations of zoologists and botanists.</p> <p>Description. Length 12–26 mm; 54–74 segments; diameter in X 0.4–0.7 mm. Prostomium with proboscis, the latter 300–600 µm long, diameter about 80 µm at middle. Secondary segmentation well marked from IV–IX, weak in postclitellar segments (Fig. 3A). Chaetae moderately sigmoid, with nodulus slightly distal to midpoint (0.35–0.45 the distance from the tip); in anterior bundles 113–204 µm long, shorter in II, dorsals similar in length to ventrals; in mid body segments 120–216 µm long (Fig. 3B). Genital pores all on the longitudinal lines of ventral chaetae. Male pores on prominent dome-shaped porophores (26–84 µm high, 64–120 µm wide) in X, midway between chaetae and septum X/XI (Figs. 3D,E, 4A). Two pairs simple spermathecal pores in XI and XII; those in XI midway between chaetae and posterior septum; those in XII very close to posterior septum (12/13) (Fig. 3 C–E). Female pores on 11/12.</p> <p>Epidermis 9–24 µm thick in anterior segments, up to 40 µm in clitellum. Clitellum in X–XIII (XIV), not greatly thickened in most specimens. Pharyngeal glands in IV–VI (VII). First nephridium at 12/13 or 13/14; pores anterior to ventral chaetae, nephridial duct tubular at pore, without forming a vesicle.</p> <p>Sperm sacs extend anteriorly to VIII or VII, posteriorly to XIII–XIX; egg sacs extend 1–2 segments beyond. Male funnels on 9/10 and 10/11. Vasa deferentia 18–24 µm diameter, about 250–400 µm long; posterior vasa loop into XI; both vasa join the atrium near mid-length and enter the muscle layer, opening to atrial lumen near the (ental) apical end (Figs. 3 C–E, 4C). Atria short, 172–310 µm long, entirely in X, club-shaped, ampulla gradually narrows towards the pore, not clearly separated from the ectal duct; atrium length 0.3–0.5 times body width at segment X, and 2–3 times the porophore width (Fig. 4A,B). Maximum atrium diameter 38–69 µm; epithelial cells 5–10 µm thick; atrial muscle layer thin (3–6 µm); prostate glands 10–22 µm high, usually appearing as a continuous layer over most of the atrium, but in some specimens they can be seen as distinct clusters (Fig. 4C). No obvious glands at the ectal pore.</p> <p>Spermathecal ampullae oval or sac-like, the first pair about 150–700 µm long, the second pair similar or slightly smaller, 170–480 µm long, sometimes without sperm (Fig. 3D). Spermathecal ducts 40–85 µm long, 25–35 µm maximum diameter, tapered to the pore (Figs. 3 C–E; 4D–F); duct epithelium with columnar cells, usually with a gradual transition to the thinner epithelium of the ampulla (Figs. 3E, 4E).</p> <p>Remarks. Eremidrilus humboldti n. sp. resembles the Pacific Coastal E. ritocsi Fend &amp; Rodriguez, 2003 in the size of the atrium relative to the body diameter, and the male porophore is also similar. However, E. ritocsi has only one spermathecal segment, and the spermathecal pores are near the lateral line. Spermathecal morphology also differs: ampullae are more globular in E. ritocsi, with a characteristic sperm arrangement, and ducts are longer and more tubular (Fend &amp; Rodriguez 2003). As in other inland species described here, E. humboldti n. sp. has two spermathecal segments; spermathecae have short, tapered ducts, spermathecal pores are in line with ventral chaetal bundles, and the pores of the second pair are close to intersegment 12/13. It is distinguished from other species of the region by its small atrium (Table 2) and by the broadly rounded male porophore, with a simple pore (Fig. 4A).</p> </div>	https://treatment.plazi.org/id/03D287B7A57DFFC8FF7D6FF0F09EFD1E	Public Domain	No known copyright restrictions apply.

Gustafson.</p> <p>Etymology. Named for the State of Montana, location of the type locality.</p> <p>Description (based on specimens from the type locality). Length of preserved worms 17–26 mm; 61–91 segments; diameter in X 0.5–0.8 mm. Prostomium with proboscis, the latter 250 µm long in the single individual where complete, diameter 30–80 µm. Secondary segmentation from IV, weak in posterior segments (Fig. 5A). Chaetae two per bundle, with nodulus slightly distal (0.4–0.5 distance from tip) (Figs. 5B, 6A); in preclitellar ventral bundles length 142–218 µm, shorter in II (115–146 µm); in middle segments 162–226 µm, in posterior segments 142–232 µm; length of dorsal chaetae similar to ventrals. Male pores open on or slightly lateral to ventral chaetal lines (Figs. 5A,C, 6B), between chaetae and posterior septum (Fig. 5E); porophores absent or inconspicuous (Figs. 5C, 6B,C). Two pairs simple spermathecal pores in XI and XII, behind ventral chaetae, on the ventral chaetal line (Figs. 5D, 6F,G), the anterior pair about 2/3 distance from chaetae to posterior septum, the posterior pair very close to 12/13. Female pores on 11/12.</p> <p>Epidermis 12–26 µm thick in preclitellar segments, thinner (8-15 µm) in post-clitellar segments. Clitellum in X to XIV, clitellar epidermis somewhat thickened (20-35 µm), with glandular cells in specimens with mature eggs Pharyngeal glands in segments IV or V to VI (VII). First visible nephridium at 12/ 13 in most specimens, pore anterior to ventral chaetae; in posterior segments the duct may be slightly expanded (to about 30 µm) at the nephridiopore, forming a small vesicle.</p> <p>Paired testes in IX and X, ovaries in XI; sperm sacs extend anteriorly to VIII or more, posteriorly to XIII–XVII; egg sacs extend 1–2 segments beyond. Male funnels on 9/10 and 10/11, 110– 165 µm high. Two vasa deferentia per atrium, both 20–30 µm in diameter, and about 400–600 µm long. Posterior vasa deferentia loop back into XI; both anterior and posterior vasa join atrium at about the ental third of ampulla, running within atrial musculature and opening to atrial lumen near the apex (Figs. 5E,F, 6E). Atria entirely in X, 280–408 µm long, or 0.5–0.7 times body width at segment X; club-shaped, ampulla not clearly separated from the duct; duct narrows gradually towards pore. Maximum atrium diameter 73–89 µm; epithelial cells somewhat columnar, 7–19 µm high in ampulla (Fig. 6E); atrial lumen variable, to 25 µm. Atrial muscle layer 12–16 µm thick; all but a short ectal portion of atrium covered with a dense layer of short cells (11–16 µm high) beneath a thick layer (60–150 µm high) of densely packed, multicellular prostate glands that appear highly granular (Fig. 6 C–E). No obvious glands at the male pore (Fig. 6C).</p> <p>Spermathecal ampullae oval or sac-like, the first pair 360–530 µm long, the second pair about 2/3 the size of the first pair, each restricted to one segment, sometimes filling most of the segment. Ampullar epithelial layer not obviously glandular, mostly 9–15 µm thick, cells may be somewhat vacuolized near duct, up to 30 µm thick (Fig. 6G). Ectal ducts of spermathecae 80–160 long, sharply differentiated from ampulla, diameter 40–68 µm near ampulla, tapered to the pore (Figs. 5D,F, 6G,H); the ducts of the second pair as long as or slightly shorter than those of the first pair.</p> <p>Remarks. The species is distinguished from all other Eremidrilus species by the absence of a distinct male porophore. The club-shaped atria, with very large, dense prostate glands, and the thick epithelium and muscle layer are also distinctive. As in other congeners with two spermathecal segments, spermathecae open on the ventral chaetal lines, with the second pair posteriorly placed, close to intersegment 12/13. Unlike E. artzaini and E. humboldti n. spp., spermathecal ducts are sharply distinguished from the ampulla. Although this is the only Eremidrilus species without a distinct male porophore, other characters such as the proboscis, the club-shaped, semiprosoporous atrium and the postatrial spermathecae support its attribution to the genus. A continuous layer of cells covering the atrial ampulla, basal to the prostate gland layer has been also observed in E. elegans and E. coyote Fend &amp; Rodriguez, 2003 (Fend &amp; Rodriguez 2003).</p> </div>	https://treatment.plazi.org/id/03D287B7A57FFFC7FF7D6A20F70DF80E	Public Domain	No known copyright restrictions apply.

Nephridia in several postclitellar segments, terminating in a round vesicle (30 µm wide), anterior to ventral chaetae (Figs. 7C, 8G).</p> <p>Atria 240–340 µm long, entirely in X, club-shaped, maximum diameter 52–77 µm; muscle layer thin, 2–4 µm; epithelial cells cuboidal, to 6–7 µm high. Atrial ampulla covered with a prostate layer, 20–30 µm thick, prostate cells in densely packed clusters (Figs. 7C,D, 8D). Atrium narrows to 20 µm before porophore, and to about 10 µm near the male pore, which opens on a narrowly cylindrical porophore (26–50 µm long, 30–33 µm wide). Atrium length about 9–10 times porophore width, and 0.6–0.7 times body width. Two vasa deferentia per atrium, diameter 19–24 µm, length about 300 µm; posterior vas loops in XI, and both vasa join the atrial muscle layer near the middle, entering the lumen at about one third the distance from tip. (Fig. 7C,D)</p> <p>Spermathecae in XI and XII, ampullae may extend into next segment (Fig. 7C). Ampullae irregular sac-like, epithelial layer about 8 µm thick (Fig. 8E). Ectal ducts of spermathecae 60–90 µm long and up to 50 µm wide, usually tapered to about 20 µm near the pore; muscle layer thin (ca. 1 µm), lining cells somewhat columnar, about 12 µm high; lumen very narrow (Fig. 8F). Spermathecal pores without glands or distinct epidermal modifications.</p> <p>Remarks. The position of the spermathecal pores in line with the ventral chaetae, with the second pair close to intersegment 12/13, is similar to that of other Eremidrilus species having two spermathecal segments. Male pores open on a short porophore, narrower than that of E. humboldti n. sp. and E. allegheniensis (see below), and markedly different in shape from the concave, annular porophore of E. artzaini (a porophore is absent in E. montanensis n. sp.). The small size of the atrium and the thin atrial musculature most closely resemble those of E. humboldti, but in that species the atrium is shorter and the porophore is relatively large (see Table 2). The nephridial vesicles, observed in middle segments, appear more distinctive than those of E. montanensis.</p> </div>	https://treatment.plazi.org/id/03D287B7A572FFC2FF7D6A15F14EFCA2	Public Domain	No known copyright restrictions apply.

NMC 3471, 3472, 2 dissected paratypes from the type locality, Tennessee, Franklin Co., Round Mountain Cave, (7 miles Northeast of Still Fork, Alabama); in rimstone pool, 30 July 1967.</p> <p>Remarks. Eremidrilus allegheniensis was described in detail by Cook (1971), based on four museum specimens. A paratype (USNM 43491) was reexamined by Rodriguez &amp; Giani (1994) and the holotype (USNM 43490) by Fend &amp; Rodriguez (2003). The two additional specimens examined here confirm several characters that effectively distinguish the eastern North American E. allegheniensis from the new western species having two spermathecal segments. The allegheniensis atrium is more elongate and tubular (Table 2), commonly extending into adjacent segments (Fig. 9A,B; see also Fig. 1A in Cook 1971); it is densely covered by a thick layer of prostate glands in densely-packed, distinct clusters (Fig. 10A), and the ectal end (at the base of the porophore) is somewhat muscular, then narrowing within the porophore. The vasa deferentia are free for most of their length, only penetrating the atrial wall near the apical end.</p> <p>Some additional characters visible in the present material also appear noteworthy. The atrial epithelium of E. allegheniensis is thick (over 20 µm) and glandular (Fig. 10A,B), particularly compared with that of E. artzaini, E. humboldti, and E. gilita n. spp. The spermathecae have sacciform ampullae, short ducts and unordered sperm, as in other species with two spermathecal segments (Figs. 9A, 10F); however, E. allegheniensis spermathecal pores terminate on distinctive papillae (Fig. 10D,E). Among the other described Eremidrilus species, only E. felini Fend &amp; Rodriguez, 2003 has strongly modified spermathecal pores, but those open within laterally placed sacs (see Figs. 13 f,g in Fend &amp; Rodriguez 2003). A pair of large (copulatory?) glands, adjacent to the ventral chaetae in XIII (Figs. 9B, 10E) was seen in both E. allegheniensis paratypes examined here, and a smaller pair of similar glands was present anterior to the chaetae in XII. These glands are multicellular, with conjoined ducts terminating on a small secretory surface, and resemble copulatory glands in some other lumbriculid genera (e.g. Fend et al. 2015). They have not been observed in other Eremidrilus species, but also were not mentioned in prior E. allegheniensis descriptions.</p> </div>	https://treatment.plazi.org/id/03D287B7A575FFC2FF7D6E2CF076F8F1	Public Domain	No known copyright restrictions apply.
