Cuticle coarsely annulated, annuli -2.4–3.4 µm -wide at midbody and 2.2–3.0 µm wide in pharyngeal region. Cuticle tessellated: longitudinal striae giving it a tiled appearance, each block often with a central indentation as seen under SEM. Anteriorly, 9–10 first annuli, the longitudinal striation is irregular and blocks rounded, followed by a more regular striation creating rectangular blocks, 16 rows of blocks at midbody (excluding lateral field). Lateral field consisting of two wings separated by a broad groove, appearing as four incisures under LM, occupying about 20–25% of body diameter, extending almost to tail terminus in females and to midtail papillae in males, two outer incisures extend to tail terminus in males. Lip region slightly offset, carrying 6 + 4 papillae and two round amphids. Three pairs of asymmetrical lips, one dorsal and two ventrolateral. Pairs of lips separated by U-shaped primary axils without guarding processes. Each pair with a shallow incisure demarcating a secondary axil. Each lip asymmetrically rectangular with a smooth margin, without any tines. Three labial probolae, 8.0– -9.5 µm -high, bifurcated at half of their length, prongs bent toward one another apically (“snake-tongue”-shaped). Stoma somewhat longer than lip region diameter. Stomatal parts not clearly discernible. Cheilorhabdia bacilliform in lateromedian view; metastegostom with a dorsal denticle. Pharynx cephaloboid. Pharyngeal corpus cylindrical; isthmus narrow, often folded, and not clearly demarcated from corpus; bulb oval, with valves. Nerve ring at level of metacorpus to metacorpus-isthmus junction. Excretory pore and deirids at level of metacorpus-isthmus junction to isthmus. - - -Female - -Reproductive system monodelphic, prodelphic, in dextral position in relation to intestine. Ovary reflexed posteriorly at oviduct, ovary straight posterior to vulva. Spermatheca well developed. Postvulval uterine sac one to one-and-a-half times vulval body diameter long. Vagina about one-third of vulval body diameter. Vulval lips not or slightly protruding, anterior lip with cuticular flap directed posteriad and partly covering vulval opening. Vulva covered by genital plug in some specimens. Tail conoid with 13–15 ventral annuli, terminus truncate. One specimen has a tail with only 10–11 annuli and broadly rounded terminus.

- - - - -Remarks - - - -The population collected from sand in the Kelso Dunes area, Mojave Desert, California and described here, agrees in many respects with the -type -specimens of - -Stegelleta incisa - -described from Utah by -Thorne (1937) -and a bisexual population described from -Italy -by -Orselli & Vinciguerra (2002) -under the name - -S. ophioglossa - -. One major difference is the presence of a cuticular flap on the anterior vulval lip directed posteriad and partly covering the vulval opening, as seen by SEM in the present specimens. This feature is not easily seen with light microscopy, which probably explains why it was not mentioned by -Thorne (1937) -in his original description. -Orselli & Vinciguerra (2002) -also did not mention or illustrate it in their specimens, presumably for the same reason. - - - - \ No newline at end of file diff --git a/data/03/DC/87/03DC879A012540037F35FE2DFDAFFBA0.xml b/data/03/DC/87/03DC879A012540037F35FE2DFDAFFBA0.xml deleted file mode 100644 index c54f1ef6cb2..00000000000 --- a/data/03/DC/87/03DC879A012540037F35FE2DFDAFFBA0.xml +++ /dev/null @@ -1,178 +0,0 @@ - - - -Descriptions of species of Stegelleta Thorne, 1938 (Nematoda, Rhabditida, Cephalobidae) from California, New Zealand and Senegal, and a revision of the genus - - - -Author - -Boström, Sven -528300CC-D0F0-4097-9631-6C5F75922799 -Department of Zoology, Swedish Museum of Natural History, Box 50007, SE- 104 05 Stockholm, Sweden & Email: sven. bostrom @ nrm. se (corresponding author) & urn: lsid: zoobank. org: author: 528300 CC-D 0 F 0 - 4097 - 9631 - 6 C 5 F 75922799 -sven.bostrom@nrm.se - - - -Author - -Holovachov, Oleksandr -89D30ED8-CFD2-42EF-B962-30A13F97D203 -Department of Zoology, Swedish Museum of Natural History, Box 50007, SE- 104 05 Stockholm, Sweden & Email: oleksandr. holovachov @ nrm. se & urn: lsid: zoobank. org: author: 89 D 30 ED 8 - CFD 2 - 42 EF-B 962 - 30 A 13 F 97 D 203 -oleksandr.holovachov@nrm.se - -text - - -European Journal of Taxonomy - - -2014 - -2014-06-16 - - -87 - - -1 -19 - - - -journal article -22008 -10.5852/ejt.2014.87 -8ba6e51d-e141-47f2-9929-73127f823066 -2118-9773 -3835107 -691BA51C-6882-4437-A037-0E8861DCBF17 - - - - - -Genus - -Stegelleta -Thorne, 1938 - - - - - - - - - -Stegella -Thorne, 1937: 4 - - -[junior homonym of - -Stegella -Stechow, 1919 - -]. - - - - - - -Stegelleta -Thorne, 1938: 64–65 - - -. - - - - - - - -Type -species - - - - - -Stegella incisa -Thorne, 1937 - -. - - - - -Diagnosis -(emended after - -Holovachov -et al. -2009 - -) - -Cuticle annulated, without distinctly annulated internal layer; annuli with longitudinal incisures (tessellated).

+ + + + +Remarks + + + +The population collected from sand in the Kelso Dunes area, Mojave Desert, California and described here, agrees in many respects with the +type +specimens of + +Stegelleta incisa + +described from Utah by +Thorne (1937) +and a bisexual population described from +Italy +by +Orselli & Vinciguerra (2002) +under the name + +S. ophioglossa + +. One major difference is the presence of a cuticular flap on the anterior vulval lip directed posteriad and partly covering the vulval opening, as seen by SEM in the present specimens. This feature is not easily seen with light microscopy, which probably explains why it was not mentioned by +Thorne (1937) +in his original description. +Orselli & Vinciguerra (2002) +also did not mention or illustrate it in their specimens, presumably for the same reason. + + + + + + +Stegelleta laterocornuta + +sp. nov. + + + + + + +urn:lsid:zoobank.org:act: +7669B17A-D71A-46C0-8BA0-EB92F28B7111 + + + +Figs 1F–J +, +3 +, +Table 2 + + + + + + +Stegelleta + +sp.

Three pairs of asymmetrical lips, one dorsal and two ventrolateral. Pairs of lips separated by U-shaped primary axils without guarding processes. Each pair with a shallow incisure demarcating a secondary axil. Each lip asymmetrically rectangular with a smooth margin and one acute tine extending along the primary axil.

Cheilorhabdia bacilliform in lateromedian view; metastegostom with a dorsal denticle. Pharynx cephaloboid. Pharyngeal corpus cylindrical; isthmus narrow, not clearly demarcated from corpus; bulb oval, with valves.
