|Distribution||San Andres Island (SW Caribbean)|
Type locality: San Andrés Island (between Morgans Cave and Punta Sur), Departamento de Archipielago de San Andrés, Colombia flocated between 12° 28° and 12° 36'N, and 81° 40' and 81° 44'W.
|Types||Holotype: UMMZ 127884, unsexed adult|
|Diagnosis||Diagnosis. Mabuya berengerae is a particularly uncommon species which can be easily distinguished from all other Mabuya species, including its closest relative M. pergravis, by the following combination of characters: an extremely long, slender and pointed snout, the highest number ofenlarged nuchal scales ofany known species of Mabuya (Table l in MIRALLES 2006), a high number of subdigital lamellae under the fourth toes (19) and a contrasting reticulated pattern on the upper side of the head, the neck and the back, also unique in the genus. Caidedo 2014 provides a diagnosis in Spanish.|
Diagnosis. Alinea berengerae is characterized by (1–2; the holotype, the only known specimen, was not sexed in the original description) SVL, 59.5 mm; (3) snout width, 2.55% SVL; (4) head length, 19.0% SVL; (5) head width, 11.9% SVL; (6) ear length, 1.43% SVL; (7) toe-IV length, 12.8% SVL; (8) prefrontals, two; (9) supraoculars, four; (10) supraciliaries, four; (11) frontoparietals, two; (12) supralabial below the eye, six; (13) nuchal rows, one (see Remarks); (14) dorsals, 59; (15) ventrals, 65; (16) dorsals + ventrals, 124; (17) midbody scale rows, 28; (18) finger-IV lamellae, 14; (19) toe-IV lamellae, 19; (20) finger-IV + toe-IV lamellae, 33; (21) supranasal contact, Y; (22) prefrontal contact, N; (23) supraocular-1/frontal contact, N; (24) parietal contact, Y; (25) pale middorsal stripe, N; (26) dark dorsolateral stripe, N; (27) dark lateral stripe, Y (weakly visible, anteriorly); (28) pale lateral stripe, N; and (29) palms and soles, pale (Tables 3–5).
Within the Genus Alinea, it is distinguished from A. lanceolata by having fewer midbody scale rows (28 versus 30–32), a longer head (head length 19.0% versus 16.3–17.8% SVL), longer toes (toe-IV length 12.8% versus 9.25– 10.8% SVL), an attenuate body shape (non-attenuate in A. lanceolata), and absence of ventral striping. From A. luciae, it is distinguished by having supralabial six (versus five) below the eye, a higher number of dorsals (59 versus 54–57), an attenuate body shape (not attenuate in A. luciae), and an absence of ventral striping. From A. pergravis, it differs by having fewer dorsals (59 versus 62–63), fewer ventrals (65 versus 70–73), and fewer combined dorsals and ventrals (124 versus 132–136) [HEDGES & CONN 2012].
Marisora berengerae n. comb. and Marisora pergravis n. comb. differ from the two (remaining) species of Alinea, A. lanceolata and A. luciae, in having a more attenuate body shape (versus heavier-bodied in Alinea) and in lacking ventral striping (versus ventral striping present in Alinea) (McCranie et al. 2020).
|Comment||Conservation: Possibly extinct.|
Abundance: only known from the type locality (Meiri et al. 2017).
Distribution: see map in McCranie et al. 2020: 317 (Fig. 6).
|Etymology||The species name (berengerae) is a feminine genitive singular noun referring to the first name of the spouse of the describer, Bérengère (Miralles 2006a).|
