Poecilantrops baorucensis sp. nov.

( Figs. 176 , 233 )

Description. Head orange. Occiput, orbital plates and bases of interfrontal setae, gena, a band on face below lunule and antenna, and frontal plate around postocellars, through middle of ocellar triangle, and around bases of ocellar bristles with microtomentum. Ocellar bristles just anterior to median ocellus. Anterior genal bristle about 0.3X length of vibrissa, subvibrissal bristle about 0.5X length of vibrissa.

Thorax black, covered with microtomentum except for a patch extending from proepisternum and the ventral half and anterior two-thirds of the anepisternum, stretching ventrally to the katepisternum behind the fore coxa, and meron. Microtomentum on scutellum densest medially, sparse laterally. Halter white. Acrostichal setae in 4 irregular rows. Proepisternum with 1 seta.

Fore leg with coxa and trochanter orange, femur brown to dark brown with sharply-defined apical yellow band, tibia orange to brown, tarsus yellow to brown. Mid leg with coxa and basal half of femur brown to dark brown, trochanter and apical half of femur orange, tibia oange to brown, tarsus yellow. Hind leg with coxa and basal two-thirds of femur dark brown to black, trochanter and apical third of femur orange, tibia brown to dark brown, tarsus orange to brown. Mid tibia with row of anterodorsal, 1 preapical and 1–2 median posterodorsal, 2–3 anteroventral, 1 posteroventral, ring of 4 subapical bristles. Hind tibia with 1 long ventroapical, length about 1.5X width of tibia.

Wing dark brown, white spots on crossveins r-m and dm-cu, at tip of R 2, on R 4+5, 1 basal and 2 distal to r-m, 1 on CuA 1.

Abdomen with tergites black, covered with microtomentum. Syntergite 1+2 with a median ridge. Tergites 1+2 and 3 fused. Sternites square, well-sclerotized in males, weakly sclerotized in females. Males with strong lateral setae on tergites 4 and 5.

Male postabdomen: Sternite 5 cup-shaped, with medium to long thin anterior apodeme, posterior margin notched (see Fig. 185 ). Surstyli asymmetrical, left surstylus more strongly produced anteriorly, both scooped with distal portion scooped. Postgonite with lobes approximated, posterior lobe short, narrowly rounded, anterior lobe broad, truncated. Basiphallus swollen, without distinct epiphallus or preepiphallus. Distiphallus short, with short smooth dorsal tube, not projecting past flanking spike, ventral sclerites very short ( Fig. 176 ).

Female postabdomen: Tergites 6–7 wider than long, weakly sclerotized medially, with weakly sclerotized posterior strips. Tergite 8 with anterior margin notched, posterior half covered with microtomentum. Epiproct parallel-sided, with short anterior arms, posterior half covered with microtomentum, with 2 setae. Cerci short. Sternites 6–7 slightly wider than long, evenly but weakly sclerotized, with weakly sclerotized posterior strips. Sclerites of sternite 8 broadened apically, with microtomentum on posterior half. Hypoproct lozenge shaped, covered with microtomentum and setae. Spermathecae round, slightly longer than wide, with apex projecting slightly, sclerotized duct about 0.3X length of spermethecae.

Type material. Holotype ♂: DOMINICAN REPUBLIC: Pedernales: Las Abejas , 30 km N of Caba Rojo, 1300 m, cloud forest, 17 Jan 1989, S.A. Marshall, debu01039251 ( DEBU) . Paratypes: same data as holotype but dung vac., 19 Jan 1989 (4 ♂, 2 ♀, DEBU) ; as above but sweep (3 ♀, DEBU) ; as above but J.E. Swann (1 ♀, DEBU) ; Sierra de Baoruca , Las Abejas Valley, 1300 m, cloud forest, 17 Jan 1989, L. Masner (1 ♂, DEBU) .

Comments. The species name refers to this species’ occurrence in the Sierra de Baoruco. It may be endemic to this mountain range; it is not known from the other mountain ranges in the Dominican Republic, where P. dominicus has been collected. The arid Valle de Nieba separating the ranges is a significant ecological barrier; flooding of the valley has repeatedly separated the Sierra de Baoruco as a separate island, as recently as the Pleistocene interglacials ( McLaughlin et al. 1991, Mann et al. 1991), and Baoruco endemics have been documented in other animal taxa. Although not yet recorded from Haiti, this species may occur there if similar habitats have been preserved.
