Peckia (Euboettcheria) calixtoi n. sp.

( Figs. 38, 39 )

Description. Male. Length. 10.7 mm. Head. Ocellar setae stronger than postoculars. Outer vertical seta stronger than postoculars. Orbital setae black. Three 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 = 1 + 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 grey microtrichosity. Abdomen in lateral view with grey microtrichosity. ST1+3 with only black setae. Three lateral setae on each side of T4. Terminalia. ST5 orange. Medial margin of ST5 ∩-shaped. ST5 arms with acute apophyses anteriorly. 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 pair of rounded projections at the base, with dorsal margin curved in lateral view, and cercal prongs progressively narrowing towards the apex. Cercus with a dorsal preapical projection with short, robust setae with the true (ventral) apex smooth without setae. Surstylus brown, finger-shaped with anterior margin slightly projected towards the anterior body region, with a rounded apex. Pregonite tongue-shaped, curved with an acute apex in lateral view. Postgonite elongated, with a hooked apex. Basi- and distiphallus connected by a desclerotized strip. Distiphallus considerably longer than cercus. 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 an equibroad tube. 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, with a serrated apex.

Female. Unknown.

Variable features. The following differences were observed in the type series as compared with the holotype: 4 setae situated below the dorsal limit of the lunule in lateral view. Hind tibia with 2 setae in the basal third, 1 in the middle third and 1 preapical on antero-dorsal surface. Two lateral setae on each side of T4.

Taxonomic remarks. The shape of phallus in this species is similar to that in Peckia (Euboettcheria) nicasia but the texture is rough in the last one and smooth in P. (Euboettcheria) calixtoi . Also, the cercus in P. (Euboettcheria) calixtoi has the base more enlarged and the projection in a ventral hook is thicker than in P. (Euboettcheria) nicasia and P. (Euboettcheria) percussa . The vesica in the new species is serrated but simple in P. (Euboettcheria) nicasia .

Biology. Unknown.

Distribution. NEOTROPICAL— Puerto Rico.

Etymology. The specific epithet is given in honour of Calixto Ruiz, the grandfather of the first author.

Holotype. Male, PUERTO RICO, Luquillo National Forest, El verde, 4–17.xii.1968 [no collector] ( USNM).
