Peckia (Euboettcheria) abrupta (Lopes)

( Figs. 25, 27 ) (figs. 7–14 in Lopes 1954, fig. 103 in Lopes 1958)

Paraphrissopoda (Euboettcheria) abrupta Lopes, 1954: 85 . Peru, Callao. Holotype male, in MNRJ (examined).

Description. Male. Head. Ocellar setae stronger than postoculars. Outer vertical seta stronger than postoculars. Black orbital setae. Genal setae black. Four frontal setae situated below the dorsal limit of the lunule. Thorax. Chaetotaxy: acrostichals = 0 + 1, dorsocentrals = 0 + 3 (anterior one shorter), intra-alars = 2 + 2 (anterior one shorter), supra-alars = 2 + 3, basal scutellars = 4. Prosternum and posterior surface of hind coxa with black setae. Three 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 almost to its posterior margin. Mid femur with a ctenidium. Antero-dorsal surface of mid tibia with 2 median setae and 1 apical seta. Hind femur with a row of antero-ventral and a row of postero-ventral setae. 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. T5 with golden microtrichosity. Microtrichosity of the abdomen laterally golden. ST1+3 with only black hair-like setae. Terminalia. ST5 orange. Medial margin of ST5 ∏-shaped. Inner margins of ST5 arms straight with a patch of short setae on the median region. Posterior margin of ST5 bent ventrally with long hair-like setae. 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 curved. Cercal prongs with the apex twisted to the median line in dorsal view. Cercal apex acute in lateral view, with numerous short, robust spine-like ventral setae. Surstylus orange, finger-shaped with anterior margin slightly projected towards the anterior body region, with a rounded apex. Postero-distal surface of surstylus as sclerotized as the rest of surstylus. Pregonite tongue-shaped, curved in lateral view, with an apical incision, a lateral projection, and an undulated apex. Postgonite elongated, with a hooked apex. Basi- and distiphallus connected by a desclerotized strip. Juxta without demarcated connection with the phallic tube. Juxta sclerotized and composed of one long plate without juxtal lateral plate and juxtal horns. Juxta with the lateral edges folded ventrally, resembling a tube narrowed towards the apex. Juxtal apex curved dorsally. Distiphallus with a pair of lateral styli separated, each with a longitudinal cleft. Short vesica composed of one entire plate without demarcated connection with the distiphallus.

Taxonomic remarks. Peckia (Euboettcheria) abrupta is morphologically very close to P. (Euboettcheria) asinoma , and their status as separate species needs to be further tested from a study of a larger material than has been available for the present work. The major differences we have been able to find relate to 1) the shape of the cercal tip in lateral view, which is acute in P. (Euboettcheria) abrupta but rounded or slightly truncated in P. (Euboettcheria) asinoma and 2) the shape of the pregonite, which is bent at almost a right angle in P. (Euboettcheria) asinoma , while the angle is distinctly obtuse in P. (Euboettcheria) abrupta .
