| Diagnosis | Diagnosis: The most variable member of the veraepacis group; most easily distinguished from A. daryi and A. veraepacis by its bright orange, red, or pale brown ground color. The vertebral scale row is pale in coloration when the middorsal stripe is absent, thereby distinguishing this species from A. daryi and A. veraepacis: when present, it involves only the vertebral scale row, thereby distinguishing this species from A. latifasciatus. In most specimens the venter is unpigmented, distinguishing A. nigrilatus from A. daryi and A. veraepacis, whereas in a few specimens the possession of heavy pigmentation midventrally distinguishes A. nigrilatus from A. latifasciatus, and it lacks the dark anterior edging characteristic of A. daryi and A. veraepacis. Adelphicos nigrilatus may be distinguished from A. latifasciatus by having fewer subcaudals (21-26) and 26—36 in males and females, respectively) and relatively shorter tail in males and females, 13.5—18.9% (16.2%) and 10.3— 12.9% (11.6%) of the total length, respectively. Female A. nigrilatus generally have fewer ventrals than do those of A. veraepacis and A. latifasciatus (Campbell & Ford 1982). |

| Etymology | The name nigrilatus is derived from the Latin nigri meaning black, and lotus meaning side, and refers to the distinctive lateral stripes on the body. |
