Leptophis dibernardoi Albuquerque, Santos, Borges-Nojosa & Ávila 2022: 10 View Cited Treatment . Male holotype ( CHUFC 1104 ; examined). Type locality: Messejana (03°49ʹ51″S, 38°29ʹ10″W, 28 m asl), municipality of Fortaleza   GoogleMaps , state of Ceará, Brazil.

Diagnosis. Leptophis dibernardoi can be distinguished from its congeners by the following unique combination of character states: (1) head scales not edged with black and with no black spots; (2) adult color pattern with no dark dorsal bands; (3) two dorsolateral stripes separated from each other by vertebral stripe one to one and a half scales wide in adults, at least anteriorly; (4) dorsals keeled, except first dorsal row on each side; keels not black; (5) no loreal scale; (6) ventrals 158–171 in males, 160–177 in females; (7) subcaudals 137–160 in males, 144–162 in females; (8) dorsal scales of tail keeled until point at which reduction from six to four scales occurs; (9) maxillary teeth 21–24; (10) TL/SVL: 95% CI = 0.585 –0.611 (n = 24); (11) small spines at first basal row of hemipenial body; (12) asulcate side of hemipenis similar to sulcate side.

Comparisons. Leptophis dibernardoi is distinguished from all members of the L. ahaetulla complex, except L. ahaetulla , by having two dorsolateral stripes separated from each other by a vertebral stripe extending onto the tail (vs. no dorsolateral stripes). Leptophis dibernardoi is similar to L. ahaetulla in its dorsal coloration, with both species sharing the pattern of two green dorsolateral stripes separated by a vertebral stripe, at least anteriorly. However, in life, the first (on the anterior region of trunk) to fourth (middle to posterior region) dorsal scale rows are White to Pale Sulphur Yellow (92) in L. dibernardoi (vs. second to fourth rows Sulphur Yellow [80]). The Jet Black (300) postocular stripe is wider in L. dibernardoi than in L. ahaetulla , occupying the lower half or two-thirds of the anterior temporal and most of the lower posterior temporal (vs. lower edge of the anterior temporal, with lower edge to one-third of lower posterior temporal pigmented). The snout is wider and shorter in L. dibernardoi than in L. ahaetulla . In life, the dorsal background color of L. dibernardoi is Light Emerald Green (142) to Robin’s Egg Blue (161) (vs. Light Grass Green [109] to Light Emerald Green [142] in L. ahaetulla ). It is further distinguished from the occasionally sympatric L. liocercus by having supracephalic scales not edged with black (vs. edged with black, Figs. 16A View FIGURE 16 , 17 View FIGURE 17 ).

Variation and sexual dimorphism. We refer to Albuquerque et al. (2022) for variation and sexual dimorphism.

Hemipenial morphology. We refer to Albuquerque et al. (2022) for hemipenial morphology.

Coloration in life. We refer to Albuquerque et al. (2022) for coloration in life.

Distribution and natural history. We refer to Albuquerque et al. (2022) for distribution and natural history.

Remarks. Prior to its recognition as a distinct species, several studies (see cresonymy above) had already recorded Leptophis dibernardoi as L. ahaetulla . However, Albuquerque et al. (2022) recognized the composite nature of Oliver’s (1948) ahaetulla and documented the existence of a new species apparently endemic to the semi-arid region of Brazil.
