'''''Gloydius intermedius''''' is a [[venomous snake|venomous]] [[Crotalinae|pitviper]] [[species]] [[Endemism|endemic]] to northern [[Asia]]. Three [[subspecies]] are currently recognized, including the [[Subspecies#Nominate subspecies|nominate subspecies]] described here.<ref name="ITIS">{{ITIS |id=634887 |taxon=''Gloydius intermedius'' |accessdate=8 August 2008}}</ref>

==Description==
[[Howard K. Gloyd|Gloyd]] and [[Roger Conant (herpetologist)|Conant]] (1990) reported examining subadults and adults that were {{convert|33.5|–|71|cm|in|abbr=on}} in total length. [[Alexander Mikhailovich Nikolsky|Nikolsky]] (1916) mentioned that some individuals may reach as much as {{convert|78|cm|in|round=0.5|abbr=on}} in total length. The body is relatively stout, and the snout is not upturned.<ref name="G&C90"/>

The scalation includes 7 [[supralabial scales]], 23 rows of keeled [[dorsal scales]] at midbody, 149-165 [[ventral scales]], and 32-48 [[subcaudal scales]].<ref name="G&C90"/>

The color pattern is variable, but generally consists of 28-45 dark subquadrate dorsal blotches or crossbands that usually extend down the flanks as far as the first or second scale rows. Between these blotches are irregular light areas. A dark brown to black postorbital stripe is present, extending from the eye back to the angle of the jaw, outlined by a light line above, and by cream-colored supralabial scales below.<ref name="G&C90"/>

==Common names==
Central Asian pit viper, intermediate mamushi, Mongolian pit viper,<ref name="G&C90"/> Central Asian pitviper.<ref name="Gum04">Gumprecht A, Tillack F, [[:fr:Nikolaï Orlov|Orlov NL]], [[Ashok Captain|Captain A]], Ryabov S (2004). ''Asian Pitvipers''. First Edition. Berlin: Geitje Books. 368 pp. ISBN 3-937975-00-4.</ref>

==Geographic range==
Found in southeastern [[Azerbaijan]], northern [[Iran]], southern [[Turkmenistan]], northwestern [[Afghanistan]], southern [[Russia]], northwestern [[China]] and [[Mongolia]]. The [[Type locality (biology)|type locality]] given by Stejneger (1907) is "Governm. [[Irkutsk]], East [[Siberia]]." Golay ''et al.'' (1993) give "Yesso (= Esso) Island, banks of [[Amur River]] and Khinggan (= Hinggan Ling) Mountain Range."<ref name="McD99"/>
