“…Even though the distinct genetic divergence of these species was confirmed by the molecular study (Makino et al 2020), and their nomenclatural statuses were resolved above, their morphological diagnoses have not been well established. Although several scalation differences were pointed out in the original descriptions of A. okinavensis and A. pellopleurus (referred to as Lygosaurus pellopleurus browni Van Denburgh, 1912a) (Thompson 1912;Van Denburgh 1912a, b), Okada (1939) negated substantial differences between the Okinawajima and Amamioshima populations and synonymized them with A. pellopleurus.…”

“…1), and the southern lineage distributed in the Okinawa Group (sites 14-22) (Makino et al 2020). Then, Makino et al (2020) concluded that these lineages deserved full species recognition. Ateuchosaurus pellopleurus was originally described based on the specimens from Ousima (= Amamioshima Island, site 11) and "Loo-Choo" (= the Ryukyu Kingdom, often interpreted as Okinawajima Island, site 15; e.g., Stejneger 1907;Okada 1939) (Hallowell 1861).…”

“…This species and its congener, A. chinensis Gray, 1845, constitute the genus Ateuchosaurus Gray, 1845. The phylogenetic distinctness and morphological diagnoses of this genus have been well described (Mittleman 1952;Makino et al 2020). Additionally, the phylogenetic distinctness and morphological diagnosis between A. pellopleurus and A. chinensis have been provided in detail (Nguyen et al 2008;Makino et al 2020;Okamoto and Kurita 2021).…”

“…A recent molecular phylogenetic study elucidated the existence of two genetically divergent lineages within A. pellopleurus: the northern lineage distributed in the Osumi, Tokara, and Amami Groups (sites 1-13 in Fig. 1), and the southern lineage distributed in the Okinawa Group (sites 14-22) (Makino et al 2020). Then, Makino et al (2020) concluded that these lineages deserved full species recognition.…”

The scincid lizard Ateuchosaurus pellopleurus (Hallowell, 1861) has been recognized as a single species widely distributed in the Osumi, Tokara, Amami, and Okinawa Groups of the Ryukyu Archipelago, southern Japan. However, a recent molecular phylogenetic study suggested that this skink should be divided into two species: one distributed in the Osumi to Amami Groups, and another distributed in the Okinawa Group. For A. pellopleurus, two extant syntypes collected from an island of the Amami Group were confirmed. Therefore, we identified the species in the Osumi to Amami Groups as A. pellopleurus sensu stricto by designating one of the syntypes as the lectotype for this species. For the species in the Okinawa Group, we resurrected A. okinavensis (Thompson, 1912), of which the type locality is on Okinawajima Island in the Okinawa Group. Ateuchosaurus pellopleurus and A. okinavensis can be differentiated by the following characteristics: usually separated frontonasal and frontal, 8–14 subdigital scales on the fourth toe (mode = 11), and usually two or three pairs of dorsal median scale rows with black stripes in A. pellopleurus; usually fused frontonasal and frontal, 10–16 subdigital scales on the fourth toe (mode = 13), and usually no stripe on the dorsal scales or a pair of dorsal median scale rows with black stripes in A. okinavensis.

“…Previously, only the karyotypes of these two species have been reported (Ota et al 1997). Recently, Makino et al (2020) studied the before origin and intraspecific diversification of A. pellopleurus by molecular phylogeographic analyses, and found that the isolation of the two sister species was caused by a tectonic event in the Miocene. Here, we determined the complete mitochondrial DNA (mtDNA) of A. chinensis via next-generation sequencing, and compared the sequences with those of other scincid lizard species to analyze its phylogenetic placement.…”

The complete mitochondrial DNA (mtDNA) for the Chinese short-limbed skink (Ateuchosaurus chinensis Gray, 1845) was described by using next-generation sequencing. The total length of mtDNA was 16,840 bp, which contained 13 PCGs (COI-III, ND1-6, ND4L, ATP6, ATP8, and CYTB), 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes, and a control region (D-loop). The Bayesian inference tree showed that A. chinensis was a sister taxon to other scincid lizards in genera of Scincella, Isopachys, Sphenomorphus and Tropidophorus. The complete mtDNA of A. chinensis will be an important genetic resource to the studies of conservation and restoration of A. chinensis.

Neoentomelas asatoi Hasegawa, 1989 is a parasitic nematode that infests only the scincid lizard Ateuchosaurus pellopleurus (Hallowell, 1861) that inhabits the forest floor in the Northern and Central Ryukyu Archipelago, Japan. As a member of Rhabdiasidae, the reproductive mode of N. asatoi is characterised by the alternation of the protandrous hermaphroditic mode and gonochoristic mode throughout the life cycle. The intrafamily phylogenetic position and intraspecific diversity of this nematode species were inferred by molecular phylogenetic analyses. The results revealed the phylogenetic distinctiveness of Neoentomelas Hasegawa, 1989 in Rhabdiasidae that supports the unique generic status of Neoentomelas within the family. The intraspecific phylogenetic analyses of N. asatoi revealed a minor concordant phylogenetic pattern with the host and mosaic geographic arrangement of the major clades that was discordant with the host. The analyses and distribution pattern of subclades suggested that this geographic arrangement can be explained by at least three dispersal events and subsequent switching to indigenous host populations. Colonisation events might be promoted by the high establishment rate of new populations stemming from the parthenogenesis-like reproduction mode of N. asatoi. This study demonstrated that reproductive modes can affect the intraspecific genetic diversity of parasites.
