Breviceps passmorei, or Passmore's rain frog or Ndumo rain frog is a species of frog in the genus Breviceps endemic to South Africa. Breviceps passmorei has extremely abbreviated snout mouth narrow and downturned; short limbs which, at rest, are held close to the body, not projecting beyond the body outline; digits tapering to apex; inner and outer toes very short or rudimentary; inner and outer metatarsal tubercles well developed, confluent or separated by a narrow groove; vent terminal, not deflected downwards.
It is located west of the Tembe Elephant Reserve in the vicinity of the Pongola River near borders of Eswatini and Mozambique, and into southeastern Limpopo Province. Breviceps passmorei is named after Neville Passmore in recognition of his contributions to South African herpetology in the field of bioacoustics, and for instilling a lifelong interest in frogs among his students, many of whom have also made significant contributions in this and other fields.

Rare
Under 5% of wildlife watchers report a Ndumo Rain Frog sighting in Kruger National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 28 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April and November–December
In those months about 10% of wildlife watchers report a Ndumo Rain Frog in Kruger National Park on a given day, against under 5% in January–March and May–October, the lowest months. Those are among Kruger National Park's wettest months, with about 55 mm of rain a month against almost none in August.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Ndumo Rain Frog sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Kruger National Park, in our data
Kruger National Park is the only park on Wallace's Line with enough records to rate Ndumo Rain Frog sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ndumo Rain Frog is recorded against all the amphibians logged in Kruger National Park (12 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
