Type locality: Lower Volga River, Russia; "Salt Lake near the Lugaskoi Sawod [factory] on the Upper Yenisey” [Siberia, Russia], according to Gloyd and Conant, 1990:319. Redefined as Naryn or Ryn Peski desert, near the Russia-Kazakhstan border by Bour (1993:335). Terra typica restricta. Lugaskoi Zavod (Strauch, 1873). Small salt lakes near Lugaskoi Za- vod, Upper Yenisey River (= “Lugaskoi Zawod, obe- res Jenissei Gebiet”) [ORLOV & BARABANOV 1999]

Distribution: see maps in ORLOV & BARABANOV 1999.

Subspecies: Agkistrodon halys ussuriensis and other subspecies have been elevated to full species status.

Synonymy: The status of Trigonocephalus affinis GRAY 1849 remains unclear. MCDIARMID et al. 1999 list it as synonym of G. blomhoffi. GUMPRECHT et al. (2004) do not recognize the subspecies liupanensis, mogoi, and affinis.

Type species: Trigonocephalus Halys — BOIE 1827 is the type species of the genus Gloydius HOGE & ROMANO-HOGE 1981, a replacement name for Halys GRAY 1849, which is pre-occupied by Halys FABRICIUS 1803 (Hemiptera). See also MCDIARMID et al. 1999 for further discussion.

Type specimens: Not located (fide MCDIARMID et al. 1999).

Diagnosis (halys). Dorsal scales in 23 rows at midbody (very seldom 21 or 25); ventrals 141 – 187, sub- caudals 29 – 56; 7 – 9 supralabials. Total length up to 750 mm [ORLOV & BARABANOV 1999].

Diagnosis (boehmei, sensu Nilson, 1983). Total length 438 mm and tail 49 mm. Snout slightly raised. Dorsal scales, except lowermost row, strongly keeled on body and tail. At midbody scale rows are 23, apical pits absent. Two pre- and two postoculars on each side. Supralabials 7, sublabials 11. Ventrals 155, subcaudals 35, anal not divided [ORLOV & BARABANOV 1999].

Diagnosis (caucasicus). Total length up to 660 mm. Supra- labials 7 – 8, rarely 9; dorsal scales in 23 rows at midbody (rarely 25); ventrals 142 – 169; subcaudals 31 – 46 [ORLOV & BARABANOV 1999].

Diagnosis (cognatus). Total length up to 590 mm. Supralabials 7 – 8; dorsal scale in 23 rows at midbody, sometimes 21; ventrals 153 – 165; subcaudals 36 – 54 [ORLOV & BARABANOV 1999].

Diagnosis (stejnegeri). Supralabials 7 – 8; dorsal scales in 23 rows at midbody; ventrals 147 – 165; subcaudals 39 – 46. Total length up to 625 mm [ORLOV & BARABANOV 1999].

Activity Pattern. Diurnal and night.

Reproduction. Viviparous.
