Description of female terminalia.
Posterior margin of T5 triangular, brown with gray microtrichosity and with a row of robust setae near posterior margin (
Figs 84–86
). T6 divided into two halves, yellow, with golden microtrichosity and a row of robust setae near posterior margin (
Fig. 81
). Spiracle 6 located on intersegmentary membrane, spiracle 7 located on T6. T8 absent (
Figs 81, 84
). Epiproct triangular, covered with fine setae. Cercus covered with long and fine setae. Hypoproct triangular, covered with fine setae (
Fig. 82
). ST6 square, covered with setae distally and with robust setae near posterior margin. ST7 square, with short, sparsely distributed setulae and a median depression. ST8 reduced, wider than long, with a row of median setulae and two pairs of robust, median setae (
Fig. 81
). Spermathecae globular, with grooves and a small rounded chamber where they receive the spermathecal duct (
Fig. 83
).

Remarks.
Peckia
(
P.
)
hillifera
is very similar to
P.
(
P.
)
lutzi
, since them both have gena and parafacial with gray microtrichosity; males have vesica with a rounded lobe proximally and apex hook-shaped, and females have T5 with a triangular posterior margin. In addition, these species are both associated to coastal environments. However, males of
P.
(
P.
)
hillifera
differ from those of
P.
(
P.
)
lutzi
in having juxtal lateral plate square and short (shorter than length of phallic tube), as opposed to pointed and longer than length of phallic tube (
Fig. 16
). Females of
P.
(
P
.)
hillifera
have ST8 wider than long and spiracle 6 located on the intersegmentary membrane (
Fig. 81
), while in
P.
(
P
.)
lutzi
ST7 and ST8 are fused and spiracle 6 is located on T6 (
Fig. 87
).
Peckia
(
P.
)
hillifera
has been recorded from
Bahamas
,
Cuba
,
Jamaica
,
Mexico
,
Panama
,
Puerto Rico
,
Trinidad &
Tobago
,
Venezuela
and the
USA
, and the above records are the first for
Brazil
. It seems to be restricted to coastal environments of the Brazilian Amazon such as mangrove forests and beaches, where it is relatively common. We reared some specimens from a dead crab [
Ucides cordatus
(Linnaeus)].
