DistributionSW Costa Rica (Pacific coast, especially Osa peninsula), NW Panama

Type locality: "tropical rainforest 9 km northern [sic] of Ciudad Neily in southeastern Provincia de Puntarenas, Costa Rica."  
TypesNeotype: UCR (given as MZUCR) 23185, adult male, designated by Solórzano & Sasa 2020. Holotype: ICP (also as MICP, Universidad de Costa Rica) 301, apparently now lost; paratypes: MICP 302–307. Entiauspe-Neto 2021 stated that the neotype designation by Solórzano & Sasa (2020) is invalid as it did not clarify the taxonomic status or the type locality (Article 75.3.1). 
DiagnosisDiagnosis. Distinguished from other species of Lachesis by having the dorsum of the head completely black. 

Distribution: see maps in González-Maya et al. 2014, Solórzano & Sasa 2020, and Barrio-Amorós et al. 2020 (Fig. 28). 
EtymologyThe specific name melanocephala is derived from the Greek melanos (= black) and kephalos (= head), an allusion to the solid black top of the head in this species.
