bare. Male: scutellum with a pair of reduced apical setae; vesica with a ventral, sclerotized lobe (
Fig. 6D–E
); juxta folding around tip of paraphallus and with numerous spine-like processes (

). [Female unknown.]
Etymology
The species epithet ‘

’ should be treated as a noun in apposition. The name refers to the province where the

locality of the new species is located.

Description
Male
(n=1)
Length:
8 mm
. Differs from
D. phoenix
sp. nov.
as follows:
Frons about 0.25 × head width at level of ocellar triangle; 10 well-developed frontal setae reaching level of apex of pedicel; first flagellomere approximately 4× as long as pedicel; thorax with slightly yellowish-silver pollinosity (
Fig. 3F
); intra-alars 2 +2, postpronotals 2; meral setae 5–7; scutellum with pair of reduced apical setae; abdomen dark brown, with golden pollinosity; T5 with row of 12 marginal setae; cercus with pointed apex (
Fig. 6B–C
); surstylus trapezium-shaped in lateral view (
Fig. 6B
); pregonite almost straight, 1.5× length of postgonite and with broad base (
Fig. 6D
); vesica consisting of membranous and sclerotized areas and with ventral dark lobe with 2–3 spines (
Fig. 6D–E
); juxta equipped with numerous spines (
Fig. 6D–E
); median stylus with enlarged base and narrow apex, slightly shorter than lateral stylus, base curved towards ventral and dorsal margins of paraphallus and with apical spines (
Fig. 6D–E
); lateral stylus with base slightly curved towards ventral margin of paraphallus and with apical spines (
Fig. 6D–E
).
Female

Remarks
Dexosarcophaga limon
sp. nov.
is morphologically similar to
D. petra
sp. nov.
and
D. paulistana
(Lopes, 1982)
by having a vesica with a rounded lobe in lateral view (
Figs 6D
,
7D
;
Lopes 1982a
: fig. 58).
Dexosarcophaga limon
sp. nov.
and
D. petra
sp. nov.
can be differentiated from
D. paulistana
by the distally completely rounded vesica (
Figs 6D
,
7D
) and with a digitiform projection distally in
D. paulistana
(
Lopes 1982a
: fig. 58). Males of
D. limon
sp. nov.
can be differentiated from those of
D. petra
sp. nov.
by the following features: ST5 with arm-like processes almost parallel-sides in middle part, apically rounded, and almost half as long as sternite (
Fig. 6A
), cercus almost straight in lateral view (
Fig. 6B
), and juxta with small spines apically (
Fig. 6D–E
). In
D. petra
sp. nov.
, these features appear as follows: ST5 with arm-like processes gradually tapering, apically pointed and distinctly shorter than half of sternite, and with two small but distinct lobes projecting near the midline (
Fig. 7A
); apical half of cercus curved anteriorly (
Fig. 7B
), and juxta with small spines only at base (
Fig. 7D–E
).
