Orinodromus Neumanni subsp. ufiomae Basilewsky, 1962: 65 (type: Ufiomi; Museum für Naturkunde Humboldt Universität, Berlin)

Length 16-20 mm. As the species that are found on Kilimanjaro, neumanni has the rear lobes of pronotum, provided with setae. Basing on this characteristic, Jeannel (1940) placed it, together with the species of Kilimanjaro, in the subgenus Orinodromus s. str.
Unlike the other species of the group, however, that have smooth elytra, neumanni has its elytra, characterized by 15 intervals on each of them; that means having a single tertiary interval on the sides of a secondary one ("triploïde" type). Also all the intervals have the same width and heigth ("omodyname" sculpture) and are distinctly separated by striae. The upper body is black with reddish elytra, with light metal luster. Even the pronotum may have bronze purple metallic luster on its sides, or both elytra and pronotum may completely lack metallic reflections (ufiomae).
neumanni was described on specimens captured on the crater of mount Hanang, 250 km south west of Kilimanjaro. Subsequently Basilewsky (1962:65) described the subspecies ufiomiae from the crater of the mount Ufiomi, about 50 km from mount Hanang, near the nature park of Tarangire. The description was based on minimal differences concerning the sculpture of elytra, namely the reduction of the foveae on primary intervals, and the lack of any metallic luster on the entire upper body.
neumanni (including ufiomiae that we believe does not deserve to be considered at the level of subspecies) occupies then the two contiguous major mountain ranges in the south west of Mount Kilimanjaro (crater of mount Hanang, and mount Ufiomi), from 1900 up to 2400 m.

Examined specimens
Tanzania: Dar es Salaam (MNHN); Mt Hanang, vers. Sud, 2350m, (RMCA); Mount Hanang, 2200m. (SB) Manyara, Mount Hanang (SB), Ufiomi, D.O.A. (paratype of Orinodromus Neumanni subsp. ufiomae Basilewsky, RMCA), Mount Ufiomi (NMB), Mount Ufiomi, Babati 1900m (EM, SB)..

Notes: Wingless. Contrary to the previously supposed rarity (Basilewsky, 1962: 64.), it has been found again recently living on the alpine meadows with Graminaeae, on both the typical localities.
Catches are reported from May to June, after the long rains, and from September to October, before the short rainy season, as it happens with most of the other alpine species of Kilimanjaro area.
The species is named after Oscar Rudolph Neumann (1867 – 1946) a German zoologist and ornithologist, who has traveled extensively in Africa, in particular between 1892 and 1894.
