Calliphora maestrica
Peris, Gonzalez-Mora, Fernandez, and Peris, 1998
: 49.
This species was originally described from the Sierra Maestra region,
Cuba
based on four female specimens. Five males and ten females were examined to characterize this species. The authors described the unusual condition in this species of only two katepisternal setae (see
Fig. 9
) and noted it has an orange basicosta which is found in only one other New World
Calliphora

vicina
. The genitalia in both sexes are highly modified and unlike any
Calliphora
in the Nearctic or mainland Neotropical Region.
Diagnosis.
Basicosta orange, a character shared only by
C
.
vicina
in the New World; two, rather than three katepisternal setae which is the condition found in all other known New World
Calliphora
; male frons exceptionally broad, 0.29 of head width, nearly as broad as female frons (0.33 of head width); male surstyli forceps-like, cerci fused and withdrawn into base of surstyli; ovipositor unlike other
Calliphora
in the Neotropical Region.
Measurements.
Male
frons exceptionally broad, 0.29 (0.028–0.30/5) of head width, only slightly narrower than female frons width, which is 0.33 (0.32–0.33/5) of head width.
Male
genitalia.
Surstyli forceps-like, cerci fused and withdrawn between bases of surstyli (
Fig. 10
). When surstyli are pulled down, posterior end of phallus and pre- and postgonites are exposed (
Fig. 11
). Phallus (
Figs.12–13
) with epiphallus strong and curved down, at base joining distal part of basiphallus. Paraphallus ends in a hook curved sharply downward and acrophallus long and slender; it is unclear if there are lateral ducts, although pale curved channels in
Fig.
13
may represent them. Hypandrium as in
Fig. 14
. Pregonite has a dense row of about 10 setae; postgonite robust and has a single tiny seta (
Fig. 15
). Ejaculatory sclerite large and fan-shaped (
Fig. 16
). ST 5 of the male very broad (
Fig. 17
).
Female genitalia.
T6 very short and broad for
Calliphora
with a wide, weakly sclerotized area in middle, and an inverted v-shaped notch posteriorly (
Fig. 18
). Posterior margin of the sclerite has a row of strong setae which extends up the edge to the paired spiracles; there are no microtrichia on this segment. ST6 broad, with wide rows of setae posteriorly and laterally; with microtrichia on the posterior quarter of segment. T7 divided medially by a Y-shaped area of weak sclerotization; posterior edge of each half has inward extensions. ST7 large and somewhat oval with hind portion almost isolated by a membranous area, posterior edge has a strong row of setae. T8 halves widely separated; ST8 reduced to two small triangular sclerites with setae posteriorly.
