| Diagnosis | Diagnosis: Rhadinaea hannsteini is a small brownish snake with a pale, broken neck-ring, a dark vertebral line, and several additional lines or stripes on each side. It has 17 scale rows and thus differs from related species characterized by 19 or 21 rows, and the several well-defined dark lines distinguish it from several small species that have a pale collar but no dark lateral lines. Rhadinaea hannsteini can be distinguished from the remaining members of the godmani group (R. kinkelini, R. lachrymans, R. pinicola) in having only one postocular, rather than two, and in details of color pattern. The species is most likely to be confused with R. kinkelini (q.u.) and, although the number of postoculars separates all specimens examined, close attention should be given to the illustrations of heads and body patterns; in addition to the slight differences in body striping, it will be noted that hannsteini lacks large pale areas on the frontal plate, whereas such markings are characteristic of kinkelini and some other members of the godmani group.

| Etymology | Named after Walter Bernhard Hannstein (b. 1902), a German whose father emigrated to Guatemala (1892). In the 1940s he bought a coffee plantation, Finca La Paz, which is still owned and managed by his descendants (fide Beolens et al. 2011). |
