Resembles the sympatric B. helmrichi closely in external appearance, but B. zacapensis has a uniform pale tan color on the underside of the tail and lacks any mottling on the ventral side, whereas the subcaudal surface is orange or pink in B. helmrichi with mottling on the venter, gular region, and underside of limbs. Bolitoglossa zacapensis has less interdigital webbing compared with B. helmrichi: sinuosity = 1.90 + 0.11 [mean + SD, N = 10] vs. mean 1.80 + 0.07, N = 14 for B. helmrichi (Jaekel 2002; Jaekel and Wake 2007). Compared with B. helmrichi, B. zacapensis has a relatively longer tail (males: TL/ SVL 0.696–1.032, mean 0.909, N = 12 for B. zacapensis vs. 0.504–1.089, mean 0.814, N = 25 for B. helmrichi; t = 2.344, P = 0.030; females: 0.701–1.012, mean 0.887, N = 10 for B. zacapensis vs. 0.652–0.972, mean 0.781, N = 20 for B. helmrichi; t = 2.820, P = 0.015), and relatively shorter (significantly shorter for males) fore and hind limbs (males: FLL/SVL 0.254–0.286, mean 0.267, N = 12 for B. zacapensis vs. 0.246– 0.322, mean 0.282, N = 25 for B. helmrichi; t = 3.466, P = 0.002; HLL/SVL 0.247–0.289, mean 0.270, N = 12 for B. zacapensis vs. 0.267–0.339, mean 0.296, N = 25 for B. helmrichi; t = 4.644, P = 0.0001; females: FLL/SVL 0.238–0.279, mean 0.258, N = 13 for B. zacapensis vs. 0.245–0.286, mean 0.265, N = 21 for B. helmrichi; t = 1.736, P = 0.095; HLL/SVL 0.540–0.296, mean 0.273, N = 13 for B. zacapensis vs. 0.257–0.306, mean 0.282, N = 21 for B. helmrichi; t = 1.695, P = 0.106).
Description: A moderately sized species of Bolitoglossa. Head moderately broad; snout truncate; eyes weakly protuberant, barely visible when viewed from below; relatively shallow postorbital groove extends posteriorly from eye to the posterior end of the mandible, where it proceeds sharply ventrally and continues weakly across the gular region. Maxillary teeth abundant, premaxillary teeth anterior to line of maxillary teeth, do not pierce lip. Premaxillary teeth more numerous in females than in males. Moderate number of vomerine teeth extending in an irregular row just past outer edge of internal nares. Oval mental gland present in males. Labial protuberances moderately well developed. Tail somewhat rectangular at base, becoming more round towards tip; weakly constricted at base; tail relatively long, approximately same length as body. Limbs slender and relatively short; adpressed limbs separated by approximately two costal grooves. Webbing reduced with two phalanges of Digit III free of webbing on both hands and feet. Digit tips bluntly rounded with distinct subterminal pads; digits in order of increasing length I-II-IVIII on hands and I-II-V-IV-III on feet. Phalangeal formulae 1-2-3-2 for hand and 1-2-3-3-2 for foot. Brown in color; some individuals with thin yellowish lines running from head to hind limbs.

Etymology: Named for the Departmento de Zacapa, Guatemala, in which it was discovered and likely is restricted to. The authors of the original description suggest "Zacapa Salamander" as its English common name.
