DiagnosisDiagnosis. Asthenodipsas lasgalenensis sp. nov. is distinguished from all other species of the Pareatidae by the unique combination of having of a maximum TL 771 (Smedley 1931); 15/15/14–15 dorsal scale rows167–190 ventrals; 54–77 subcaudal scales; one or two postorbitals; 1–2+1–3+1–2 temporals; 6–8 supralabials and infralabials; whitish ventral scales bearing small dark lateral spots; dorsum of adults unicolor dark brown; dorsum of hatchlings and juveniles bearing an orangish to light gray ground color overlain with 42–56 irregularly shaped rhomboidal darker bands beginning posterior to dark nuchal bar and extending the length of body and tail and onto lateral spots; edges of ventral scales but not encircling body; a light vertebral stripe; whitish labials usually edged in darker color; dark brown to black head; dark red to red-orange eyes. These character states are summarized across all species in Table 3 (LOREDO et al. 2013). 
CommentHabitat: partly arboreal (Harrington et al. 2018). 
EtymologyThe specific epithet lasgalenensis is derived from the name Eryn Lasgalen which means in the “Wood of Greenleaves” in the fictional Sindarian language from J.R.R Tolkien’s The Lord of the Rings (1955). It was the name used by the Wood Elves for the Mirkwood Forest after its cleansing following the War of the Ring. This name was chosen because Tolkien’s (1955) description of this forest showed great similarity to the cloudy, upland forests within which this species is found.
