First record of Scincella fansipanensis Okabe, Motokawa, Koizumi, Nguyen, Nguyen & Bui, 2024 (Squamata, Scincidae) from China
No full textThe Fansipan ground skink, Scincella fansipanensis Okabe, Motokawa, Koizumi, Nguyen, Nguyen & Bui, was recently described from Fansipan Mountain, Lao Cai Province, northern Vietnam. Herein, we report the first national record of this species from China, based on four specimens collected from Ailao Mountain, Jingdong Yi Autonomous County, Yunnan Province.Morphologically, the Chinese specimens are consistent with the type series, but differ slightly in possessing a higher number of ventral scales (including gulars) and relatively shorter fore-limbs. Phylogenetic analyses, based on CO1 sequences, place the Chinese specimens within the S. fansipanensis clade; however, uncorrected p-distances of 6.5–7.3% between the Chinese and Vietnamese populations suggest moderate genetic divergence. This level of differentiation may reflect historical isolation by the Red River Basin's complex topography and the low dispersal ability of Scincella species. This record raises the number of the genus Scincella species known from China to 15

Pheretima sp. 11 – Nguyen 2013: 78, 2014: 111. Type locality. Viet Nam (Kien Giang: Lai Son island) (Nguyen et al. 2017b) Type material. Laboratory of Zoology, Department of Biology, Can Tho University (EW.087.01), Vietnam. Diagnosis. Body cylindrical, length 62–114 mm, diameter 2.7–4.4 mm, segments 62–111. Prostomium epilobous. First dorsal pore at 12/13. Three pairs of spermathecal pores in lateral intersegments 6/7/8/9, bithecate. Two pairs of ellipsoid genital markings in xvii and xix, each genital marking with a small opening at the center. Male pores located inside copulatory pouches in xviii. Septum 10/11 only present ventrally. Intestinal caeca simple. Holandric, testis sacs separated. Accessory glands coelomic, strongly covered by muscular-walled bursae in 17/18 and 18/19. Habitat. The subspecies were found numerously in leaf litters in natural forest (Nguyen 2014; Nguyen et al. 2017b). Distribution. Only known in Vietnam (Kien Giang: Lai Son island; An Giang: Cam mountain) (Nguyen 2014; Nguyen et al. 2017b) (Fig. 3). Remarks. Nguyen et al. (2017b) described a new subspecies, M. peguana laisonensis found in Lai Son Island (Kien Giang Province, Vietnam) based on the location of genital markings, spermathecal pores, and the attachment of the spermathecal diverticulum (Fig. 5) (Nguyen et al. 2017b). Previously, Nguyen (2013) identified samples collected from the Cam Mountain (An Giang Province) as M. bahli (Fig. 6), and observed that these samples have intermediate characters between M. bahli and M. peguana, for example, slit-shaped genital markings in xvii and xix, and the much laterally wider spermathecal pores (Nguyen 2013). The re-examination confirmed that specimens were definitely M. peguana laisonensis. There was a minor difference in the ending of the spermathecal diverticulum between the type specimens from Lai Son Island and samples collected from the Cam Mountain (An Giang Province) (attached directly to the base of the ampulla duct vs. attached to the middle of the ampulla duct). Genetic distance of M. peguana laisonensis in Cam Mountain and M. peguana peguana was 12.2%±1.4%, and that distance with other Metaphire species was 12.9%±1.5% (with M. bahli (type I)) to 22.3%±2.1% (with M. grandiverticulata) (Table 4).

Head scalation smooth; rostral convex, distinctly visible from above, in broad contact with frontonasal, which is broader than long; no supranasals; prefrontals in broad contact with one another; 5 supraoculars on left side and 4 on right side; a pair of frontoparietals, shorter than frontal; frontal narrowing posteriorly, longer than wide, bordered laterally by first two supraoculars, anteriorly by prefrontals, and posteriorly by frontoparietals; frontoparietals in contact with the second to fifth supraoculars on left side and the second to fourth supraoculars on right side; parietals in contact posteriorly, behind the interparietal; no nuchal; 7 supralabials on both sides, the fifth and sixth below the eye; 2 loreals, posterior loreal larger than anterior; nostril in center of nasal, which is in contact with the first supralabial, rostral, anterior loreal, and frontonasal; 8 supraciliaries, first largest; 1 anterior temporal, in contact with sixth and seventh supralabials; 2 secondary temporals, lower temporal overlapping upper one and in contact with seventh supralabial, upper temporal larger, in contact with parietal; lower eyelid scaly, 2 scales in center larger than scales in posterior and anterior areas; 6 infralabials, first pair medially in contact with each other; 1 anterior and 2 postmentals. Dorsal scales smooth, not larger than lateral and ventral scales; 34 midbody scale rows; 61 paravertebral scales; ventral scales smooth, in 60 rows; 112 subcaudal scales, slightly enlarged posteriorly; 11 and 20 smooth lamellae beneath finger IV and toe IV, respectively; 2 enlarged precloacal scales. Hemipenes. Each hemipenis deeply forked and asymmetrical with two smooth lobes. In fully everted position, the inner lobe is shorter and the outer lobe is much longer. Clear sulcus spermaticus starts from the base, divides into two branches at the fork and extends to the tips of the two lobes; body of the long lobe forming regular transversal shallow grooves and ending with terminal papillae. Short lobe obtuse, not forming regular transversal shallow grooves (Fig. 1F). Coloration. In life, overall dorsal coloration black (Hex #000000) to dark brown (Hex #654321) with two interrupted copper (Hex # B87333) dorsal lines in margins of dorsum extending from neck to base of tail; black and interrupted lateral lines under the copper ones; dorsum with irregular black spots; lateral side and lower part of head, neck, and tail orange (Hex #FF6600) to red (Hex #FE2712); venter from chest to tail base yellow (Hex #FFD300) to cream (Hex # FFFDD 0); upper side of limbs black with bright dots. Lateral margins of supralabials and infralabials with black blotches. Free margin of upper eyelid orange and the margin of lower eyelid yellow (Hex #FFD300). Eyes black. In preservation, color fades; orange and yellow disappear; overall dorsal coloration black with two interrupted brighter lines in margins of dorsum extending from neck to base of tail; venter zebra white (Hex #F5F5F5). Variation. Table 2 summarizes variation in size and scalation of the holotype, paratypes, and referred specimen. Supraoculars four in all specimens except for the left side of the holotype which bears 5 scales. Midbody scale rows vary from 32 to 34. Paravertebral and ventral scale rows range from 61 to 69 and from 58 to 67, respectively. Hemipenes of the second paratype ITBCZ 5684 (Fig. 3) similar to those of the holotype in being deeply forked and asymmetrical. Natural history. All specimens were collected at night and under rotting leaf layer in evergreen forest (Fig. 5), elevations 932 m and 1162 m a.s.l., between 19:00–23:30. However, the species was observed being active in the daytime and it may be diurnal. Sphenomorphus yersini sp. nov. was observed to be sympatric with other congener, S. indicus. Sexual dimorphism. Males are larger than females (SVL 56 mm vs. 52 mm, n=4) and have orange (Hex #FF6600) or red (Hex #FE2712) color on lateral sides and lower part of head, neck, and tail. The color on the lateral side in females faded to yellow (Hex #FFD300) or brown (Hex #964B00) with bright spots; lower part of head, limbs, and tail white (Hex #FFFFFF) to zebra white (Hex #F5F5F5); venter from neck to vent yellow (Hex #FCE883). Distribution. The new species is currently known only from Hon Ba NR, Khanh Hoa Province, southern Vietnam (Fig. 5). Etymology. We name this new species in honor of the famous physician and bacteriologist, Alexandre Yersin (1863–1943), who discovered the bacterium responsible for bubonic plague. Hon Ba NR associates with the name of Alexandre Yersin who built a research station on the top of the mountain and worked there. Currently, the research station has been reconstructed and opened to visitors. We recommend Yersin’s Forest Skink as the common name of this new species. Comparisons.
