|Diagnosis||Diagnosis (genus): A widespread African genus extending extralimitally onto the Arabian Peninsula, diagnosed by the following combination of characters: body moderately elongated and tail moderate to short; head of moderate size, flattenedabove, elongated isosceles trapezoidal in shape, broader than neckand distinct from it; eye moderate to large with vertically ellipticalpupil; midbody scale rows 23–35, vertebral row not enlarged; dorsal scales smooth with one or two apical pits; ventrals 168–246,without lateral keel; subcaudals paired (usually) or single (olivaceus), 38–85; anal entire; maxilla with six enlarged anterior teeth,separated (usually) by a short diastema from 12 to 16 smaller, sub-equal, ungrooved teeth; hemipenis shallowly forked, shaft withapproximately 12 rows of basal spines; rows merge distally intochevrons and/or denticulate calyces which extend onto lobes; sulcus centrifugal, dividing approximately half way up shaft (Bogert,1940; Broadley, 1990; Branch, 1998; Chippaux, 2001). After KELLY et al. 2011 (See Table 4 in their paper for additional data).|
|Comment||Similar species: Thorpe & McCarthy (1978) showed that Lamprophis lineatus is a distinct species in West Africa rather than a color morph of L. fuliginosus, but in Southern Africa the latter species takes on the color pattern of the former. Note, however, that the two species have been confused in the literature and therefore references to either species may be erroneous.|
Type species: Boaedon lineatum DUMÉRIL, BIBRON & DUMÉRIL 1854 is the type species of the genus Boaedon DUMÉRIL et al. 1854 (LOVERIDGE 1957, revived by KELLY 2011). Note that the characters formerly used to distinguish this genus from Lamprophis have proven invalid (Broadley, 1983), and no clear morphological synapomorphies have yet been discovered to diagnose Boaedon.
Synonymy: Lamprophis capensis has been previously synononymized with L. lineatus but is now considered as a valid species by most authors. The populations from Southern Africa of Lamprophis formerly regarded as L. lineatus or L. fuliginosus are regarded by Broadley et al (2003) and Johan Marais (2004) as Lamprophis capensis. For more synonyms see BOULENGER 1893. Boaedon angolensis and B. variegatus are listed as valid by MARQUES et al. 2018 but they point out that more studies are needed to establish their validity. Boaedon bedriagae BOULENGER 1906: 211 has been revalidated from the synonymy of B. lineatus by Ceriaco et al. 2021. See that paper for a more detailed synonymy.

Distribution: not in East Africa (S. Spawls, pers. comm., 28 June 2018). Not in Gabon, where it is replaced by B. perisilvestris (O. Pauwels, pers. comm., 25 April 2019).
Key: Hallermann et al. 2020 provide a key to the Angolan species of Boaedon.
|Etymology||Named after Latin “linea”, meaning stripe or line.|
