( Figs. 71, 72 ) (fig. 2 in Dodge 1964)

Peckia (Chrysostomomyia) craigi Dodge, 1964: 52 . Mexico, Revillagigedo Is., Socorro Is. Holotype male, in CAS (not examined).

Description. Male. Head. Ocellar setae equal to or shorter than postoculars. Outer vertical seta stronger than postoculars. Black orbital setae. Four frontal setae situated below the dorsal limit of the lunule. Gena with white or yellow setae. Occipital setae white or 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. Black antero-ventral scutellar setae. 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 without a ctenidium. Antero-dorsal surface of mid tibia with 1 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. Microtrichosity of the abdomen laterally golden. ST1+3 with only black hair-like setae. Two lateral setae on each side of T4. T5 with golden microtrichosity. Posterior seam of T5 not projected posteriorly and ventrally, and normal setae in posteroventral area directed posteriorly. Terminalia. ST5 orange. Medial margin of ST5 ∏-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 posteriorly. 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 angled, with an acute apex in lateral view. Surstylus orange, triangular, with a rounded apex, with postero-distal surface less sclerotized (more smooth; lighter and more transparent colour) than the remaining surface. Pregonite triangular, becoming narrower towards the apex, curved in lateral view, with a rounded apex. 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. Juxta with lateral plate, long, curved inward, with an isosceles triangular projection on its outer margin, and a rounded apex in apical view. Distiphallus with a pair of lateral styli separated, each with a longitudinal cleft, visible in lateral and apical views. Vesica composed of two plate-like structures connected proximally and each with an acute, hook-shaped apex.

Distribution. NEOTROPICAL— Mexico (Revillagigedo Is.).
