[2] Callulina shengena is known from only two small locations in the Chome Forest Reserve in the Eastern Arc Mountains of Tanzania.

[1] Very little is known of the ecology of this species, specimens having been caught in pitfall traps, but some individuals have been seen climbing on undergrowth, low branches and tree trunks at night, at heights up to about 2.2 m (7.2 ft).

[1] The Chome Forest Reserve is being degraded by timber harvesting activities, with the valuable East African camphorwood being felled.

The ongoing destruction of its habitat does not augur well for this frog with its small range, and the International Union for Conservation of Nature has rated it as "critically endangered".
