Biology.
According to label data,
Fannia porce
sp
.
nov
.
is associated with decomposing organic matter, in forests and in rural areas in lowlands of the Central Cordillera (
770-1050 m
).
Comments.
These characters apply only to the male sex.
Fannia porce
sp
.
nov
.
is morphologically close to
Fannia sabroskyi
Seago
, but differs in the more developed
a
,
av
and
pv
on the hind femur. Both species belong to the sub-group
pusio
of the
canicularis
group.
Etymology.
Name in apposition. The species epithet refers to the
Porce
River, an extension of the Medellín River, department of Antioquia, type-locality of the species.
