Villa (Hemipenthes) inops
(Coquillett): Painter & Painter, 1965(1)
(Coquillett): Hull, 1973: 385
Explanation of Names
Genus: The wings of members of the genus "Hemi-penthes" are "half-shaded"...i.e. they have a portion of the anterior half of the wing darkened.
Specific Epithet: One meaning of the Latin word "inops" is "wanting/lacking"...and the epithet presumably refers to the fact that this species has the smallest darkened wing area among all members of the genus.
Distinct from other Hemipenthes
by: 1) largely hyaline wing with faint pigmentation; and 2) shape of the CuA1 vein...which forms a cross with a continuous m-cu/m-m such that dm and CuA1 never actually touch(2)
. (See Fig. 12 on pg. 25 of Ávalos-Hernádez(2)
for a detailed image of both the minimal wing infuscation and the distinctive wing venation just described for H. inops
Note also that H. inops is one of only two species in the genus having long, wide, black scales all along the hind femora & tibiae (the other such species is H. lepidota).
": In 2008, the original BugGuide page for this species was placed under the technically improper name Villa inops
...an inadvertent error, as that's a somewhat obscure junior synonym for this species. The mistake was noticed and changed in 2018, but had propagated to some extent over the internet...for details see this forum article
similarly has limited wing infuscation, but is found only in Mexico and lacks the CuA1 veining described above(2)
