TypesSyntypes: BMNH 1946.8.12.48-49 (and possibly additional specimens). 1946.8.12.44-45, 1946.8.12.55 original number 1859.3.14.8-12 [newtoni] 
DiagnosisDiagnosis. An Anolis of the Lesser An- tillean section of the hiniaculatus group ( as here defined) combining the following characters: prenasal posterodorsally elon- gate, extending to or beyond the anterior level of the naris; midventrals sharply keeled; interparietal in contact with supraorbital semicircles, or, if separated by one scale, then more than 23 midventrals contained in the standard distance, or, if separated by two scales, then more than 2S midventrals contained in the standard distance (Lazell 1972: 23)

Scalation: Lazell 1972: 23 (BHL scan quality too bad for OCR).

Coloration: Lazell 1972: 24 (BHL scan quality too bad for OCR).

Sexual dimorphism: well developed in both coloration and average adult size. It is not, however, nearly so striking in either respect as in some other Lesser Antillean forms. This is in keeping with the postulated position of Anolis acutus in himaculatus group phylogeny (Lazell 1972: 24). 
CommentSpecies group: Ctenonotus cristatellus species group (fide NICHOLSON et al. 2012). 
EtymologyNamed after Latin “acuere” = sharp, or “acutus” = sharpened, pointed, or “acumen” = tip, or “acus” = needle.
