Diagnosis.
Males of
E. tequendama
resemble those of
E. tropicus
(L. Koch)
and
E. valderramai
Bonaldo
by the short, excavated RTA, the extensive, sclerotized, lowered prolatero-apical sector of tegulum and by the long median prong of MA (
Bonaldo 1994: 43, 48
). They differ by the absence of a longitudinal keel on the median prong of MA, which is apically bifid (
Figs 20
, 22).
Etymology.
The specific name is a noun in apposition taken from the
type
locality.
