Poecilantrops flavifemur View in CoL sp. nov.

( Figs. 182, 186 View FIGURES 181–188 , 238 View FIGURES 231–239 )

Description. Head dark brown to black, face and clypeus brown, prementum orange-brown, antenna orange. Anterior genal bristle and one subvibrissal bristle about 0.3X length of vibrissal bristle.

Thorax mostly covered with microtomentum, scutellum, ventral three-quarters of anepisternum, katepisternum, meron, and posterior half of metapleuron shiny.

Foreleg with coxa, trochanter, and femur yellow, tibia and 2 basal tarsomeres dark brown, distal 3 tarsomeres whitish. Midleg with coxa and femur dark brown, femur becoming paler on distal third, trochanter yellow, tibia and tarsus yellow to pale brownish. Hind leg with coxa, trochanter, distal third of femur, and tarsus yellow, tibia and basal two-thirds of femur dark brown.

Wing with membrane nearly clear, veins pale brown, white spots on crossveins r-m, bm-cu, dm-cu, and 2 along vein R 4+5 distal to crossvein r-m.

Abdomen with tergites not fused. Tergites covered with microtomentum except shiny anteromedial patch on syntergite 1+2.

Male postabdomen: Sternite 5 slightly longer than wide, posterior margin notched, covered with setae and microtomentum ( Fig. 186 View FIGURES 181–188 ). Surstylus scooped, subrectangular, slightly asymmetrical with anteroventral corner of right surstylus more acutely pointed. Postgonite with lobes broadly separated, anterior lobe broad, rounded, posterior lobe narrow, short. Basiphallus swollen, no distinct epiphallus or preepiphallus. Distiphallus short, with a thin spinose dorsal tube and a long ventral projection ( Fig. 182 View FIGURES 181–188 ).

Female postabdomen: Tergite 6 barely sclerotized, tergite 7 weakly sclerotized along anterior and lateral margins, not sclerotized medially, both wider than long and without posterior strips. Tergite 8 trapezoidal, moderately sclerotized, covered with microtomentum. Epiproct parallel-sided, pointed apically, with very short anterior arms, without setae. Cerci broad. Sternite 6 barely sclerotized, sternite 7 weakly sclerotized, both square, without posterior strips. Sclerites of sternite 8 rectangular, with microtomentum on apical third. Hypoproct lozenge-shaped, covered with microtomentum. Spermathecae ovoid, about 1.75X longer than wide, annulated, sclerotized duct short.

Type material. Holotype ♂: BOLIVIA: La Paz: Coroico , 1700 m, grassy slope, dung traps, 5 Apr 2001, S.A. Marshall, debu00167708 ( UASC) . Paratypes: same data as holotype (2 ♀, DEBU, UASC); Chulumani , Apa Apa Reserve, 2000 m, pans in compost, 1–3 Apr 2001, S.A. Marshall (1 ♀, DEBU) .

Comments. The species name refers to the yellow femur in this species, unique among known Bolivian species of Archiborborinae . This species is similar to A. marensis sp. nov., but can be identified based on the shiny scutellum and unfused abdominal tergites.
