Description.
Holotype
female, length 12.3 mm, width 6.4 mm. As for
E. kidapawanus
except as follows: Integument black throughout. Rounded pale-yellow scales on pronotal disc forming two broad lines that converge anteriorly from latero-basal angle to apex, in form of an inverted “V”, these lines of scales extended onto elytral humeri and posteriorly along interstria 7 to about mid-length of elytra. Elytra with humeri prominent, angulate, glossy at tip and with row of small glossy tubercles extended from base to widest point. Elytral interstriae with elongate tubercles covered with shiny granules on interstriae 3 and 5, those on interstria 3 low, at about basal one-third of elytral length and the second one, much taller and pointed posteriorly, at apex of declivity, those on interstria 5 low, at about midlength and a second at apex of declivity adjacent to taller one on interstria 3; interval 7 with elongate tuberculate prominence just behind humeri. The
holotype
female was not dissected.

Etymology.
The new species is named after Robert E. Woodruff (1933–2021) of Gainesville,
Florida
in recognition of his interest in Philippine insects.
Diagnosis.
Aside from the obvious difference in the pattern of the pale scales on the pronotum and elytra there are some more subtle differences between the two species. The humeri in
E
.
kidapawanus
are marked by a strongly laterally protruding single glossy tubercle whereas in
E
.
woodruffi
the humeri are marked by a short series of smaller glossy tubercles that end in a slightly larger glossy tubercle at the widest point. This largest tubercle is not as strongly laterally protruding as in
E
.
kidapawanus
.
The largest elytral tubercle, located at the apex of the declivity on interstria 3 is more rounded and directed more dorsally in
E
.
kidapawanus
but has more of a pointed apex and is directed more posteriorly in
E
.
woodruffi
