Type locality: Bahia, Brazil [fide BOULENGER 1896: 240]
|Types||Neotype: BMNH.1918.104.22.168 (designated by Entiauspe-Neto et al. 2017); syntype: BMNH 1922.214.171.124; original syntypes: BMNH 19126.96.36.199 and BMNH 19188.8.131.52; the two smaller specimens illustrated in Günther (1861) are current syntypes of a different taxon, Coronelaps lepidus (Reinhardt, 1861).|
|Diagnosis||Diagnosis: Elapomorphus wuchereri can be distinguished from all its congeners by the following combination of characters: (1) dorsal scales 15-15-15, smooth; (2) postoculars two; (3) loreal absent; (4) temporals 1 + 1; (5) six supralabials, 2nd and 3rd in contact with orbit; (6) seven supralabials; (7) gular scale rows 2–4; (8) ventrals 164–188 (179–188 in females, 164–169 in males); (9) subcaudals 30–46 (30–34 in females, 40–46 in males); (10) dorsal pattern with three narrow dorsal stripes in juveniles, and faint stripes in adults on a copper or yellow background; (11) ventral surface immaculate cream; (12) snout–vent length 194–1212 mm (194–1212.7 in females, 224.5–863.6 in males, Entiauspe-Neto et al. 2017).|
Comparisons: Elapomorphus wuchereri is compared with E. quinquelineatus in Table 2 and Figure 3. Elapomorphus wuchereri differs from E. quinquelineatus (characters in parentheses) by absence of nape-cervical collars (present); ventral side of head uniformly colored (dotted), with black blotches radiating from mental groove (white background, with black circular blotches); background color varying during development, from copper to yellow (olive-brown to yellow); dorsal pattern from three narrow stripes in juveniles to faint stripes in adults (5 dark stripes reducing to 3). It is distinguished from Coronelaps lepidus by lacking a yellow parietal band and nape-cervical collars, and having a thicker body, and longer, more depressed head (rounded in C. lepidus), and fewer than 200 ventrals (more than 200 in C. lepidus, Entiauspe-Neto et al. 2017).
Synonymy: Elapomorphus accedens JAN 1861 has been removed from synonymy with E. wuchereri and synonymized with Elapomorphus quinquelineatus by de LEMA 1995.
