Peckia (Euboettcheria) asinoma (Hall)

( Fig. 22 ) (fig. 6 in Hall 1938)

Euboettcheria asinoma Hall, 1938: 259 . Ecuador, Oña. Holotype male, in DEI (examined).

Description. Male. Head. Ocellar setae stronger than postoculars. Outer vertical seta of same size as postoculars. Black orbital setae. Four frontal setae situated below the dorsal limit of the lunule. All genal setae black. First two rows of occipital setae black, others yellow. Thorax. Chaetotaxy: acrostichals = 0 + 1, dorsocentrals = 0 + 4 (anterior two 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 medial setae and 1 apical seta. Hind femur with with a row of antero-ventral and a row of postero-ventral setae. Hind tibia anterodorsally 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 hairlike setae. Two lateral setae on each side of T4. T5 with golden microtrichosity. Terminalia. ST5 orange. Medial margin of ST5 ∏-shaped, with a patch of short setae. Inner margins of ST5 arms straight. 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. Dorsal margin of cercus curved and cercal apex rounded or slightly truncated in lateral view. Cercus with subapical short spines on dorsal, lateral and ventral surface. Surstylus brown, finger-shaped with anterior margin slightly projected towards the anterior body region, and a rounded apex. Postero-distal surface of surstylus as sclerotized as the rest of surstylus. Pregonite tongue-shaped, curved in lateral view, with a lateral projection, an apical incision, 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. 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) asinoma is morphologically very close to P. (Euboettcheria) abrupta (see remarks for this species).

Distribution. NEOTROPICAL— Ecuador.
