Peckia (Euboettcheria) cacao n. sp.

( Figs. 31, 32 )

Description. Male. Length. 13.2 mm. Head. Ocellar setae stronger than postoculars. Outer vertical seta stronger than postoculars. Orbital setae black. Four frontal setae situated below the dorsal limit of the lunule in lateral view. Genal setae black anteriorly, yellow or white posteriorly. First two rows of occipital setae black, others yellow. 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 a median seta and 1 apical seta. One row of setae on ventral surface of hind femur. 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. Abdomen in lateral view with grey microtrichosity. ST1+3 with only black setae. Two lateral setae on each side of T4.

Terminalia. ST5 brown. Medial margin of ST5 Λ- shaped. Inner margins of ST5 arms convex, with a patch of short setae on the median region. 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 with a dorsal preapical huge protuberance with short, robust setae with the true (ventral) acute apex smooth without spines. Surstylus orange, finger-shaped with anterior margin slightly projected towards the anterior body region, with a rounded apex. Pregonite tongue-shaped, curved in lateral view, with an undulated apex in dorsal view. Postgonite elongated, with a hooked apex. Basi- and distiphallus connected by a desclerotized strip. Proximal section of the phallic tube very elongated, with the vesica close to the subapical opening. Juxta without demarcated connection with the phallic tube. Juxta sclerotized and composed of one long plate without juxtal lateral plate and juxtal horns. Juxta strongly angled in lateral view. The spermatic exit is directed ventrally. 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.

Female. Unknown.

Taxonomic remarks. Peckia (Euboettcheria) cacao has the juxta more enlarged than in the other species of the subgenus. The shape of cercus in this species bears some resemblance to that in P. (Euboettcheria) bifurcata and P. (Euboettcheria) cubensis but the dorsal protuberance is more developed.

Biology. Unknown.

Distribution. NEOTROPICAL— Costa Rica.

Etymology. The specific epithet is a noun in apposition and refers to the type locality.

Holotype. Male, COSTA RICA, Guanacaste province, Sector Cacao , Send. [Sendero] a cima, 1400–1500m, 13.iv.1997, F. A. Quesada ( INBio).
