Karyotype of the Chinese soft-shelled turtle, Pelodiscus sinensis, from Japan and Taiwan, with chromosomal data for Dogania subplana.

Current Herpetology (2001)

Hiroyuki Sato Hidetoshi Ota

The male and female karyotypes were examined for 10 specimens of the Chinese soft-shelled turtle, Pelodiscus sinensis, from the main islands of Japan and Taiwan by the bone marrow air-dry technique. One specimen of Dogania subplana was also examined karyologically. Although both P. sinensis and D. subplana had 2n=66 chromosomes, they showed an interspecific variation in chromosome morphology. No karyotypical differences were evident between the Japanese and Taiwanese samples of P. sinensis, or within either of them. Comparisons of the present results with previously reported trionychine karyotypes indicate that there are some interspecific and intraspecific variations in centromeric positions of several macrochromosome pairs in this subfamily.

PHYLLOPHIS CARINATA GUNTHER, 1864 (CURRENTLY ELAPHE CARINATA; REPTILIA, SERPENTES): PROPOSED CONSERVATION OF THE SPECIFIC NAME

The Bulletin of zoological nomenclature (1995)

Hobart M. Smith Hidetoshi Ota Van Wallach

The purpose of this apphcation is to conserve the specific name of Phylhpliis carimita Giinther, 1864, which has had long usage in an extensive literature, for a snake occurring in southeastern China, northern Vietnam, Taiwan and southern Japan (Ryukyus).For a very short time (March -October 1891) the species was considered to be congeneric with the Central and South American snake Coluljer carinatus Linnaeus, 1758, rendering Giinther's name a junior secondary homonym.Coluber phyllophis Boulenger, 1891 was established as a replacement for C. carinatus (Giinther, 1864) and the latter is thus formally permanently invalid.However, the name phvllophis has rarely been used and has not appeared at all since 1929.

Karyotype of <i>Pareas iwasakii</i>

Japanese journal of herpetology (1999)

Hidetoshi Ota

The standard female karyotype of Pareas iwasakii, a species endemic to the southern Ryukyus, Japan, is described. This is the first report of the chromosomal arrangement for the subfamily Pareatinae. The present material had 2n=36 chromosomes, consisting of eight pairs of biarmed macrochromosomes and ten pairs of apparently uniarmed microchromosomes. Of these, pair 4 was heteromorphic, and thus is supposed to be the ZW-sex chromosome pair. The remaining pairs appeared homologous. The karyotype of this morphologically highly specialized snake largely fits the broadly prevailing henophidian/caenophidian format, which most likely represents a primitive state of the extant colubrid karyotypes.

A New Species of Lepidodactylus (Sauria: Gekkonidae) from Sabah, Malaysia

Copeia (1988)

Hidetoshi Ota Tsutomu Hikida

A specimen of a previously undescribed form of the genus Lepidodactylus was obtained from Sabah, Malaysia. This specimen most closely resembles Lepidodactylus mutahi and L. guppyi of the Solomon Islands, but differs from any other congeneric members in several morphological characters. We, therefore, describe this gecko as L. ranauensis.

Presence of isochore structures in reptile genomes suggested by the relationship between GC contents of intron regions and those of coding regions

Genes & Genetic Systems (2003)

Kazuo Hamada Tokumasa Horiike Hidetoshi Ota Keiko Mizuno Takao Shinozawa

Vertebrate genomes are mosaics of isochores. On the assumption that marked differences exist in the isochore structure between warm-blooded and cold-blooded animals, variations among vertebrates were previously attributed to adaptation to homeothermy. However, based on the data of coding regions from representatives of extant vertebrates, including a turtle, a crocodile (Archosauromorpha) and a few kinds of snakes (Lepidosauromorpha), it was recently hypothesized that the common ancestors of mammals, birds and extant reptiles already had the "warm-blooded" isochore structure. To test this hypothesis, the nucleotide sequences of α-globin genes including non-coding regions (introns) from two snakes, N. kaouthia and E. climacophora, were determined (accession number: AB104824, AB104825). The correlation between the GC contents in the introns and exons of α-globin genes from snakes and those from other vertebrates supports the above hypothesis. Similar analysis using data for exons and introns of other genes obtained from the GenBank (Release 131) also support the above hypothesis.

Geographic Variation in the Watase’s shrew Crocidura watasei (Insectivora, Soricidae) from the Ryukyu Archipelago, Japan

Mammalia (1996)

Masaharu Motokawa Satoshi Hattori Hidetoshi Ota Tsutomu Hikida

Des analyses univariees et multivariees ont ete faites a partir de 5 mesures corporelles, 10 dimensions du crâne et de la mandibule et 21 mesures dentaires sur 94 specimens de Crocidura watasei Kuroda, 1924, collectes dans 4 iles du groupe d'Amami et dans 2 iles du groupe d'Okinawa, dans l'archipel des iles Ryukyu, au Japon. Aucun caractere n'a montre de difference entre les sexes. Des comparaisons statistiques univariees d'echantillons de trois des iles du groupe d'Amami et d'une ile du groupe d'Okinawa ont montre que deux de ces populations sont bien differenciees exterieurement par rapport aux deux autres. La meme tendance a ete montree par analyses multivariees. Bien que la taille des echantillons des deux autres iles soit trop petite pour permettre des analyses statistiques, ces derniers semblaient se rapprocher plus de l'un des deux groupes precedents que de l'autre. L'ensemble des resultats met en evidence une grande dichotomie des populations insulaires des Ryukyus avec une affinite historique plus forte des populations du sud du groupe d'Amami avec les populations d'Okinawa qu'avec les populations du nord d'Amami.

Best practices: in the 21st Century, taxonomic decisions in herpetology are acceptable only when supported by a body of evidence and published via peer-review

Herpetological review (2013)

Hinrich Kaiser Brian I. Crother Christopher M. R. Kelly Luca Luiselli Mark O’Shea

This paper was written by nine authors from five continents, and supported by a further 80 academics and many major herpetological societies including the World Congress of Herpetology, in reaction to burgeoning number of species descriptions being published in herpetology by a small number of individuals through their own self-published journals which lack any peer-review.
