Peckia (Peckia) rosalbae View in CoL n. sp.

( Figs. 94, 95 View FIGURES 90–96. 90–91 )

Description. Male. Length. 13.0 mm. Head. Ocellar setae equal to or shorter than postoculars. Outer vertical seta of same size as postoculars. Orbital setae black. Four frontal setae situated below the dorsal limit of the lunule in lateral view. Genal setae black dorsally, yellow or white ventrally. First two rows of occipital setae black, others yellow. Thorax. Chaetotaxy: acrostichals = 0 + 1, dorsocentrals = 0 + 3 (anterior one shorter), intra-alars = 1 + 2 (anterior one shorter), supra-alars = 2 + 3, basal scutellars = 3. Prosternum and posterior surface of hind coxa with black setae. Antero-ventral scutellar setae white or yellow and black. Two katepisternal setae. Postalar wall with only black setae. Lower calypter with a central dark spot and a fringe of long hair-like setae along outer margin, extending to its posterior margin. Mid femur with a ctenidium. Antero-dorsal surface of mid tibia with a median seta and 1 apical seta. Hind tibia antero-dorsally with 1 seta in the basal third, 1 in the middle third and 1 preapical. Abdomen. Postero-ventral seams between T3/T4 and T4/T5 parallel. Posterior seam of T5 not projected posteriorly and ventrally. T5 with golden microtrichosity. Abdomen in lateral view with grey and golden microtrichosity. ST1+3 with only black setae. One lateral seta on each side of T4. Terminalia. ST5 brown. Medial margin of ST5 ∩-shaped. Inner margins of ST5 arms straight. Posterior region of ST5 arms bent dorsally. Syntergosternite 7+8 longer than high in lateral view, orange, with golden microtrichosity. Epandrium bright orange. Cercus orange proximally and brown or dark brown distally. Cercus in lateral view progressively narrowing towards the apex, with the dorsal margin slightly curved, without a depression or tooth-like projection. Cercal apex acute in lateral view. Surstylus orange, triangular, with a rounded apex. Postero-distal surface less sclerotized (more smooth; lighter and more transparent colour) than the remaining surface. Pregonite triangular, with a lateral projection, and an undulated apex, and curved in lateral view. Postgonite elongated, with a hooked apex. Basi- and distiphallus connected by a desclerotized strip. Juxta without demarcated connection with the phallic tube, as sclerotized as the phallic tube. Juxtal lateral plate short with rounded apex in lateral view. Distiphallus with a pair of lateral styli strongly enlarged distally and appearing closed in ventral view. Vesica composed of two plate-like structures connected proximally, with the ventral edge angled in lateral view and each with an acute, hook-shaped apex.

Female. Unknown.

Variable features. The following differences were observed in the paratype with respect to the holotype: Chaetotaxy: dorsocentrals = 0 + 2.

Taxonomic remarks. Peckia (Peckia) rosalbae is close to P. (Peckia) nephele , but differs by the lateral styli appearing closed in ventral view and by the anteriorly acute vesica more sclerotized and smaller than in P. (Peckia) nephele . Peckia (Peckia) rosalbae and P. (Peckia) nephele have lateral styli strongly enlarged distally, whereas these structures are filamentous in other species of the genus. The usual colour pattern of the Sarcophaginae can change, exhibiting a shiny black spot on the thorax posteriorly and on the abdomen in the center.

Biology. Unknown.

Distribution. NEOTROPICAL— Colombia (Magdalena).

Etymology. The specific epithet is given in honour of Rosalba Ruiz Molina, the mother of the first author.
