Atherigona
Rondani
) with a very long postpedicel, arista with short hairs; acrostichal setulae in 2 rows before suture and 4–5 rows after suture; postsutural dorsocentrals 3, the two first shorter than the posterior one; scutellum with long basal and apical pairs of setae; lower katepisternal inserted closer to the long posterior one; lower calypter about twice the length of the upper one; fore tibia without a submedian seta; mid femur with 1 posterior preapical seta; mid tibia with 1 posterior seta; male with the first two mid tarsomeres creamy-yellow and greatly elongated; sternite 1 bare; sternite 5 as in

Notes.
The description of
L. quadristriata
was based on two females, both specimens with the head missing, but was complemented on pages 702–703 (
Emden 1951
) with the description of the male, based on additional material collected in
Liberia
in 1943 by
F.M. Snyder. This
enabled the head to be described, and
Snyder’s
male was designated as the
holotype
.
The
species can be easily recognized by the striking angular head (in profile) with a very long postpedicel and by the creamy-yellow and greatly elongated first two tarsomeres of the mid leg.
One
male dissected and illustrated.
