Peckia (Squamatodes) trivittata (Curran)

( Figs. 114, 115 ) (fig. 3 in Curran, 1927, figs. 3, 36, 41, 58, 76, 95, 97, 100, 105, 109 in Lopes 1958, fig. 59 in Carvalho & Mello-Patiu 2008)

Squamatodes trivittata Curran, 1927: 3 . Brazil, Mato Grosso, Chapada. Holotype male, in AMNH (not examined).

Squamatodes stahli Dodge, 1966: 699 . Argentina, Misiones , Eldorado [“Kol. Eldorado, Misiones am Parana ”]. Holotype female, in ZSM (examined).

Sarcophaga spitzi Lopes, 1933: 69 . Brazil, Goiás, Campinas. Holotype male, in MZUSP (not examined). Lopes (1933) used two original spellings, spitzi (p. 69) and sptzi (p. 71). By subsequent usage (ICZN Code Article 24.2.4), Lopes (1958: 228) acted as First Reviser and selected spitzi as the correct original spelling.

Description. Male. Head. Ocellar setae equal to or shorter than postoculars. Outer vertical seta of same size as postoculars. Black orbital setae. Three frontal setae situated below the dorsal limit of the lunule. Gena with white or yellow setae. Occipital setae white or yellow. Thorax. Prosternum and posterior surface of hind coxa with yellow or light brown setae. Chaetotaxy: acrostichals = 0 + 1, dorsocentrals = 0 + 2, intra-alars = 1 + 2 (anterior one shorter), supra-alars = 1 + 3, basal scutellars = 3. White or yellow and black antero-ventral scutellar setae. Two katepisternal setae. Postalar wall with white or yellow anterior setae. Lower calypter with a central dark spot, with black setae dorsally and a fringe of long hair-like setae along outer margin extending to its posterior margin. Mid femur without a ctenidium. Antero-dorsal surface of mid tibia with 1 median and 1 apical seta. Ventral surface of hind femur with 1 row of setae. Hind tibia with 2 setae in the basal third, 2 in the middle third and 1 preapical on antero-dorsal surface. Abdomen. Postero-ventral margins of T3 and to a lesser extent T4 curved posteriorly, so that segment 3 and to a lesser extent segment 4 are of near-equal length dorsally and ventrally. Posterior seam of T5 projected posteriorly and ventrally. Microtrichosity of the abdomen laterally grey and golden. ST1+3 with yellow or light brown hair-like setae. Two lateral setae on each side of T4. T5 with grey microtrichosity. Posterior seam of T5 projected posteriorly and ventrally. Postero-lateral area of T5 with setae directed towards the ventral body region. Terminalia. ST5 orange. Medial margin of ST5 Λ- shaped. Inner margins of ST5 arms straight. Inner margins of ST5 arms with a patch of short setae on the anterior region and long hair-like setae uniformly distributed. Syntergosternite 7+8 as long as 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 angulated in lateral view. Cercal apex acute in lateral view. Surstylus orange, triangular, with an acute apex. Pregonite subqadrate, straight in lateral view, with an undulated apex. Postgonite elongated, with a hooked apex. Basi- and distiphallus connected by a desclerotized strip. Phallic tube short and straight. Juxta with a demarcated connection with the phallic tube. Juxta without juxtal lateral plate. Juxta entire with a middle line dorsally forming a crest running the full juxtal length. Lateral styli fused and forming only one broad tube. Vesica absent.

Distribution. NEOTROPICAL— Argentina (Misiones), Brazil (Federal District, Goiás, Mato Grosso, Minas Gerais, Pará, São Paulo).
