Description

(n = 31). Size: length ♂, 9.1-11.5 mm; ♀, 10.2-11.5 mm; width ♂, 5.2-6.4 mm; ♀, 5.7-6.5 mm. This new subspecies differs from the nominal form by exhibiting the following characters: smaller size; black/brown markings more regularly disposed and reduced; background colour more reddish; anterior pronotal elevation more enhanced; lateral pronotal angles less round and hind part of lateral border slightly longer; antescutellar concavity weak; pilosity of sternum thinner, especially in male; parameres with lateral sides subparallel, apex with dull lateral angles, shape more squared.

Derivatio nominis.

This subspecies is named after the French collector Robert Minetti, who brought to the authors’ attention the holotype specimen from Zambia.

Remarks.

There was initially some reservation in erecting this new subspecies, despite the morphological differences with the other forms mentioned above. Only the study of a large series of Atrichelaphinis (Eugeaphinis) deplanata from various localities made it possible to isolate the new subspecies, considering also its broad geographic distribution. It is here given subspecies status because some of the specimens from Rwanda and Kenya actually represent a transition between the two forms, exhibitng intermediate characteristics such as coloration, shapes of pronotum and aedeagus. However, no potential intermediate forms were available from Congo-Brazzaville, where both subspecies are known to occur, but in separate parts of the country. Despite the Rwanda-Kenya transition zone, the new subspecies has a separate geographical distribution area from the nominal subspecies, which is restricted to western and central Africa. The new subspecies is distributed from central to east Africa and throughout the eastern half of southern Africa.
