DistributionJapan (northern and central Ryu-Kyu Islands)

Type locality: probably from the central Ryu-Kyu Islands (TAKEDA & OTA 1996)  
TypesHolotype: BMNH 1946.8.4.53-63 
DiagnosisDescription: “Head long, as in T. serlineatus, its width being contained nearly twice in its length. A series of granules, usually incomplete, between the supraoculars and the supraciliaries; a small shield usually separates the large anterior supraocular from the loreal; temporal scales obtusely keeled, much smaller than in the other species, 10 to 15 on a line between the orbit and the tympanum. Dorsal shields strongly keeled, in eight to ten longitudinal series, the three outer series on each side largest and equal; eight longitudinal series of large, strongly keeled, mucronate ventrals, and three or four series of smaller ones on each side. Præanal shield usually longitudinally divided in the female, entire in the male. One inguinal pore on each side. Emerald-green above ; a pale yellow streak along each side, from the upper lip to the groin; males usually with a broad grey or bronzy lateral band above the yellow streak; lower surfaces greenish yellow.” (Boulenger 1887: 509) 
EtymologyNamed after Latin “smaragdinus” for “emerald,” an obvious allusion to the bright green ground color of this species.
