Etymology
— The specific designation is made up of the Latin
herba
, soft usually green vegetation, referring to the host plant, plus the Latin
colus
, dweller, inhabitant.
Remarks
— The aedeagus of the
n.sp.
resembles that of
E. obtusus
Meyer, 1965
(however, in
E. obtusus
ends in a blunt tip) and that of
E. roedereri
Gutierrez, 1967
. It differs from both in leg chaetotaxy.
