DistributionIndonesia (West Papua, Manokwari)

Type locality: “Hâvre Dorey, à la Nouvelle Guinée” [Doreri Bay, West Papua Province, West New Guinea]; corrected to Manokwari area on the Bird’s Head Peninsula of West Papua, Indonesian New Guinea, by Kaiser et al. 2018.  
Reproductionoviparous 
TypesHolotype: MNHN-RA 3412, from Hâvre Dorey, Nouvelle Guinée [Doreri Bay, West Papua, Indonesia]. Collected by Prosper Garnot and René-Primevère Lesson between 26 July and 9 August 1824.
Syntypes: MTD (= MTKD) 573 and unnamed additional specimens, from Supiori I. (as Mysore), Papua Province, Indonesia. Collected by Adolf B. Meyer between 25 March and 5 April 1873. Kaiser et al. 2018 designated MTD (= MTKD) as the lectotype so that any neotype designation would only need to take the characteristics of a single specimen into account [Lycodon magnus] 
Diagnosis 
CommentSynonymy after COGGER 1983 and Kaiser et al. 2018, who removed Stegonotus reticulatus BOULENGER 1895 as well as Lydodon keyensis DORIA 1874 from the synonymy of S. cucullatus. Many reports of S. cucullatus in the literature actually refer to S. australis after this species was revalidated by Kaiser et al. 2018.

Behavior: nocturnal

Distribution: records from Australia or Papua New Guinea are in error fide Kaiser et al. 2018.

Photos: many photos supposedly showing S. cucullatus show actually other species after Kaiser et al. 2018 revised the genus.

Habitat: partly arboreal (Harrington et al. 2018). 
EtymologyAfter the Latin “cucullatus”, a literal translation of the French “capuchon” for (cape or hood), likely chosen in reference to the dark brown dorsal coloration contrasted by the yellowish-white venter.
