The latter configuration also occurs in the other three subfamilies: Lycozoarcinae Andriashev, 1939, Zoarcinae Gill, 1862 and Gymnelinae Gill, 1864 (Anderson, 1994). <i>Lycenchelys tohokuensis</i> clearly differs from species of Lycozoarcinae (including only <i>Lycozoarces regani</i> Popov, 1933) and Zoacinae (only <i>Zoarces</i> Cuvier, 1829 with six species) in having scales, and teeth on the vomer and palatine, and lacking the pelvic fins and dorsal-fin spines (vs. having pelvic fins and lacking scales in the Lycozoarcinae, and having pelvic fins and dorsal-fin spines, and lacking vomerine and palatine teeth in the Zoarcinae) (Anderson, 1994). When compared with genera of Gymnelinae, <i>L. tohokuensis</i> mostly resembles <i>Ericandersonia</i> Shinohara & Sakurai, 2006 [only 1 species, <i>Ericandersonia sagamia</i> Shinohara & Sakurai, 2006 (Fig 48)] in having similar numbers of dorsal-fin rays (112–116 vs. 113–116), anal-fin rays (93–94 vs. 93–95), pectoral-fin rays (14 vs. 14), and total vertebrae (116–119 vs.117–118), respectively (Anderson & Imamura, 2002; Shinohara & Sakurai, 2006; this study). Furthermore, numbers and arrangements of head pores in the two species are the same (2 nasal, 5 postorbital, 7 suborbital, 4 mandibular, 4 preopercular, 1 interorbital and 3 occipital pores) (Figs. 46A, B, C, 49A, B, C) (Anderson & Imamura, 2002; Shinohara & Sakurai, 2006; this study). The two are distinguishable, however, by the presence of 2 lateral lines, and a developed labial lobe on the lower jaw, and the lower edge of the gill opening set slightly above the lower end of the pectoral-fin base in <i>L. tohokuensis</i> (vs. lateral line single and mediolateral, labial lobe of lower jaw absent, and lower edge of the gill opening not reaching lower end of pectoral-fin base in <i>E. sagamia</i>) (Anderson & Imamura, 2002; Shinohara & Sakurai, 2006; this study). In addition, <i>E. sagamia</i> is characterized by the presence of a weak ridge (= pseudosubmental crest sensu Shinohara & Sakurai, 2006) on the ventral surface of the mandibula, which is absent in other zoarcid species (Shinohara & Sakurai, 2006; this study).</p> <p> The question of retaining <i>Lycenchelys tohokuensis</i> in <i>Lycenchelys</i> because of its peculiar arrangement of the suborbital bones, relative to that of other members of the subfamily needs to be tested by a phylogenetic study of the entire group.</p>Published as part of <i>Kawarada, Shumpei, Imamura, Hisashi, Narimatsu, Yoji & Shinohara, Gento, 2020, Taxonomic revision of the genus Lycenchelys (Osteichthyes: Zoarcidae) in Japanese waters, pp. 1-66 in Zootaxa 4762 (1)</i> on pages 50-55, DOI: 10.11646/zootaxa.4762.1.1, <a href="http://zenodo.org/record/3743698">http://zenodo.org/record/3743698</a>

Description — As given for genus. Frontal idiosoma margin concave. Anterior part of dorsum with spine-like structures. Male: Idiosoma 364–373 long ventrally, 356–365 long dorsally and 254–288 wide. Venter posteriorly with a short, apically rounded extension. Gonopore narrow, 24 long; an area surrounding the gonopore without idiosoma pores. Acetabula in the posteroventral sclerotization far posterior to gonopore, 7–8 pairs in irregular rows. Length of P1-P5: 18, 42, 26, 48, 22 (till tip of segment). P2 ventrally with three denticles, P3 ventrally with one denticle. Length of I-leg-4-6: 40, 44, 56 (till tip of segment). IV-leg-2 longer than other segments. Length of IV-leg-4 46, 52, 26. Female: Idiosoma 389–413 long ventrally, 381–405 long dorsally and 300–328 wide. Venter posteriorly with a pair of short, apically rounded extensions. Gonopore 64 long. Number of acetabula difficult to ascertain, but very likely around 20 pairs. Lengths of P1-P5: 18, 46, 26, 52, 24 (till tip). P2 ventrally with 2–5 denticles, P3 with one denticle. Length of I-leg-4-6: 43, 50, 56 (till tip of segment). Length of IV-leg-4-6: 49, 54, 50. Remarks — The specimens collected in this study match the description given by Imamura (1977). Imamura was not able to find the acetabula in his only male specimen. As the male was collected during a zoological expedition, and not by Imamura himself, it is likely that it was fixed in ethanol. This makes specimens dark and some structures, like the indistinct acetabula, are difficult to see. Imamura illustrated some indistinct structures posterior to the male gonopore, apparently not aware that these were the acetabula. Another feature not mentioned by Imamura is the long second segments of legs I-III, which are longer than the other segments of these legs. Habitat. Interstitial, but occasionally collected in superficial waters.Published as part of Smit, Harry, 2019, New and rare species of hyporheic water mites from New Zealand (Acari: Hydrachnidia: Aturidae, Momoniidae with the description of two new genera, one new subgenus and one new species, pp. 364-373 in Acarologia 59 (3) on pages 370-372, DOI: 10.24349/acarologia/20194339, http://zenodo.org/record/517369

External validation of Imamura nomogram as a tool to predict preoperatively laser semi-rigid ureterolithotripsy outcomes
No full textBackground: We aimed to validate Imamura nomogram for prediction of stone free rate in patients undergoing ureterolithotripsy (ULT). Methods: From January 2013 to June 2016, patients undergoing laser semi-rigid ULT were prospectively enrolled at our center. All patients were preoperatively assessed with clinical history, blood samples, uranalysis and non-contrast enhanced computed tomography (CT). Treatment efficacy was assessed 1 month later by non-contrast enhanced CT. ROC curve was used to evaluate the performance characteristics of Imamura nomogram. Results: Overall, we enrolled 275 patients. Median age was 55 years (IQR: 46/64), median length of stone was 9.8 mm (IQR: 7.5/12). Pyuria was detected in 6/275 (2.1%) patients. Stones were located at ureteropelvic junction in 55/275 (19%) patients, proximal ureter in 74/275 (26%) patients, middle and distal ureter in 66/275 (24%) patients and 82/275 (30%) patients, respectively. At 1-month follow-up, 209/275 (76%) patients were stone free. Imamura nomogram presented an AUC of 0.67 (95% CI: 0.580-0.761) for the prediction of stone free rate. At the best cut-off value of 75%, sensitivity was 76%, specificity was 55%, positive predictive value (PPV) was 83% and negative predictive value was 45%. Conclusions: We firstly validated Imamura nomogram in a European cohort study. It proved a reasonable accuracy (area under curve: 0.67) and a good PPV (83%). Further studies should confirm our results to support the routine clinical use of Imamura nomogram as a tool to predict ULT outcomes

Diagnosis. A species of Platycephalus with margin of the interopercle scalloped, skinny sensory tubes on infraorbitals and preopercle well developed, mostly covering cheek region, except for anteroventral region, and body and head lacking distinct large spots and bands dorsally. Description. Counts and proportional measurements are shown in Table 1. Body greatly depressed, mostly covered with ctenoid scales, but some cycloid scales on undersurface. Head greatly flattened, length 3.2 (3.1–3.4) in SL; snout and interorbit naked; nape, and occipital, postorbital, and opercular regions mostly scaled. Snout robust, length 3.2 (3.1–3.3) in HL, longer than orbital diameter. Upper surface of eye without papillae. Iris lappet broad, well expanded and simple dorsally, and small (broad in one paratype), simple, and weakly convex ventrally (Fig. 2 A). Interorbital width 7.2 (6.9–8.4) in HL, becoming wider with growth, shorter than orbital diameter. Spines and ridges weakly developed on top and side of head (Fig. 2 B). Nasal lacking spines. Lachrymal with two (or one in five paratypes) antrorse spines. Single preocular spine present. Suborbital ridge entirely smooth. Single postorbital spine present. Frontal ridges lacking spines. Supracleithrum with spine. Preopercle with two spines; lower spine slightly longer than upper one, not reaching posterior margin of opercle; upper lacking supplementary spine. Opercle with two spines, lacking prominent ridge. Interopercular flap absent; margin of interopercle scalloped (Fig. 3 A). Maxilla reaching beyond anterior margin of pupil, length 2.7 (2.6–2.7) in HL. Teeth in bands on jaws and palatine, and in shallowly V-shaped (or crescent in a paratype) patch on vomer; tooth band on upper jaw lacking distinct notch medially. Upper jaw with several small canine teeth anteriorly; remainder of jaw with small- to moderate-size conical teeth. Lower jaw mostly with two tooth rows, partially arranged in four rows (or partially arranged in three rows in some paratypes); inner row with longer conical teeth; outer row(s) with small-size conical teeth. Palatine with two tooth rows: inner row with longer and stouter conical teeth, outer row with small conical teeth. Vomer with small- to moderate-size canine teeth anteriorly and a few canine teeth posteriorly. Lip margins without papillae. Skinny sensory tubes on infraorbitals and preopercle well developed, mostly covering cheek region, except for anteroventral region (Fig. 3 A). Pored scales in lateral line each with one exterior opening posteriorly; opening in most pored scales directed posteroventrally, in several scales posterodorsally. First dorsal fin originating posterior to opercular margin. First and second dorsal fin narrowly separated. Pectoral fin rounded posteriorly, length 2.2 (2.0– 2.3) in HL. Posterior tip of pelvic fin reaching to third anal fin ray, length 1.2 (1.1–1.3) in HL. Caudal fin slightly rounded (or mostly flat in some paratypes) posteriorly, length 1.8 (1.7–1.9) in HL. Color in alcohol. Body and head pale brown, lacking distinct large spots and bands dorsally, whitish ventrally. Head densely covered with very small brownish spots. First and second dorsal fins with small brown spots along rays. Pectoral fin pale brown with white lower margin and scattered small darker brown spots. Pelvic fin dark brown with pale brown basal portion and whitish outer margin. Anal fin with brownish pigments along rays; membranes of posterior portion of anal fin dusky. Caudal fin blackish, with pale brownish basal area and white posterior margin; upper margin with several blackish short oblique bands continuous with middle blackish area. Color when fresh (based on color photographs of holotype): Color mostly similar to that in alcohol. Distribution. Known only from western Australia, ranging from Cape Cuvier (24 °S) to south of Cape Leeuwin (34 °S) (e.g., Hutchins, 2001; this study).

The specific name of this new species is derived from Latin for “eye”, based on its characteristic feature of a narrower interorbit. Remarks. Platycephalus orbitalis belongs to the genus Platycephalus in having pored scales in the lateral line more than 60 and a single tooth plate on the vomer (Imamura, 1996; Knapp, 1999). Platycephalus orbitalis is most similar to P. marmoratus in having a combination of following the characters: 13 second dorsal and anal fin rays; 65–68 pored scales in lateral line, each with one exterior opening posteriorly; snout and interorbit naked; lower opercular spine slightly longer than upper one; interopercular flap absent; no strong canine teeth on jaws, palatine, or vomer; skinny sensory tubes from infraorbitals and preopercle extending cheek region; and caudal fin blackish with white posterior margin. Other members of the genus Platycephalus do not possess this combination of characters (Knapp, 1991; Imamura, 2006). For example, a naked snout and interorbit are found only in P. marmoratus, P. chauliodous Knapp, 1991 and P. laevigatus Cuvier in Cuvier & Valenciennes, 1829, and the blackish caudal fin with the white posterior margin is only present in P. marmoratus among known members of Platycephalus (e.g., Imamrua, 2006). However, P. orbitalis is easily separable from P. marmoratus in having the margin of the interopercle scalloped (vs. smooth in P. marmoratus) (Fig. 3). In addition, there is a difference in the degree of the development of the skinny sensory tubes from the infraorbitals and preopercle covering cheek region; they mostly cover the cheek region, except for the anteroventral region in P. orbitalis, whereas they only partially cover it in P. marmoratus (Fig. 3). The coloration is also helpful separating these two species; viz. the body and head lack distinct large spots and bands dorsally in P. orbitalis, while they are marbled with dark brown, brown, and pale irregular bands and spots in P. marmoratus. Platycephalus orbitalis is also distinguished from P. marmoratus in having a larger orbital diameter (17.5–20.3 % HL) and narrower interorbit (11.9–14.6 % HL), the former larger than the latter in examined material (vs. orbital diameter smaller, 15.2–20.1 % HL, and interorbit wider, 13.6–21.4 % HL, the former becoming smaller than latter by 270 mm SL in P. marmoratus) (Fig. 4), although the ranges of the orbital diameter and interorbital width of the two species are partly or mostly overlapping. Finally, the range and mode of the number of the pectoral fin rays differ in P. orbitalis and P. marmoratus, and this difference is statistically significant (Mann-Whitney’s U test; P <0.01), although the ranges of these species also overlap (Table 2).

Remarks. Limnesia baderi is known from Papua New Guinea and Papua Province (Indonesia), and is reported here for the first time from Vogelkop. Very likely a species of hyporheic habitats, considering it’s pale yellow colour and the absence of eyes. Imamura (1983) considered it also an interstitial species.Published as part of Smit, Harry, 2013, New records of water mites mainly from Vogelkop, New Guinea (Acari: Hydrachnidia), with the description of one new genus and thirteen new species, pp. 207-235 in Zootaxa 3716 (2) on page 210, DOI: 10.11646/zootaxa.3716.2.5, http://zenodo.org/record/22254
