|Distribution||Myanmar (= Burma: Irrawaddy River Delta), Indonesia (Nias)|
Type locality: ‘Pegu (probably in the neighbourhood of Bassein)’ (= Bago, in southern Myanmar).
|Types||Neotype: BMNH 19188.8.131.52 (designated by MURPHY 2007: 282)|
Holotype: ZSI 8207 (but not located by Das et al. 1998).
|Diagnosis||Diagnosis (genus): Small to medium sized, with the combination of smooth scales, nasals in contact, 25 scale rows at mid-body, first three upper labials contact loreal, fourth upper labial in orbit. May be most easily confused with the snake formerly known as Enhydris pahangensis Tweedie, which has 25 dorsal scales rows, but has the first upper labial excluded from loreal (MURPHY & VORIS 2014: 21).|
DIAGNOSIS: This species has three pairs of chin shields, 123 ventrals, and a dorsal pattern of blotches without a stripe. All of which will separate it from G. vorisi, which has more than 142 ventrals and a stripe on scale rows 2–4 (n = 1; MURPHY & VORIS 2014: 22).
|Comment||Distribution: reports from China are erroneus (J. Murphy, pers. comm. 23 June 2011).|
Synonymy: Boulenger 1890 was apparently unaware of the replacement name that Blanford himself had suggested in 1881 and suggested another replacement name, Hypsirhina blanfordi.
Type species: Hypsirhina maculosa BLANFORD 1881 is the type species of the genus Gyiophis MURPHY & VORIS 2014: 21.
|Etymology||The genus has been named in honor of Ko Ko Gyi, the Burmese herpetologist who revised the homalopsids. Murphy & Voris 2014 claimed (erroneously) that the gender of the genus is feminine. It’s actually masculine, like all other genera ending in -ophis.|
