Poecilantrops crocidosternum   sp. nov.

( Figs. 178–179, 236)

Description. Head orange, occiput black, posterior two-thirds of frons mostly brown. Mostly covered with microtomentum, interfrontal plates shiny, extending to lateral ocelli, also with a shiny stripe between ocellar bristles, and a small ventromedial spot on face. Ocellar bristles about 1 ocellus width anterior to median ocellus. One subvibrissal and anterior genal bristle enlarged, about 0.3X length of vibrissa.

Thorax black, with extensive microtomentum. Proepisternum, rectangular ventromedial spot on anepisternum, spot on katepisternum behind fore coxa, and metapleuron shiny, except stripe between posterior spiracle and hind coxa. Halter white, brown below knob. Acrostichal bristles in 6 rows.

Fore leg orange, tibia except base and basal tarsomere dark brown, distal 4 tarsomeres yellow. Mid leg orange, coxa black, basal half of femur brown. Hind leg with coxa and trochanter orange, basal half of femur black, distal half orange, tibia and basal 2 tarsomeres dark brown, distal 3 tarsomeres orange. Mid tibia with 1anterodorsal, 3 posterodorsal, 1 anteroventral, 1 posteroventral, 4 subapical bristles. Hind tibia with 2 ventroapicals, length of longest less than width of tibia.

Wing light brown, white spots on crossveins r-m, bm-cu, dm-cu, at tip of vein R 2, on vein R 4+5 with 1 basal to rm, 2 distal to r-m, 1 at tip, 1 on vein M basal to dm-cu and 1 at tip, 2 on vein CuA 1 basal to dm-cu.

Abdominal tergites black, covered with microtomentum. Tergite 3 fused to tergite 2. Tergite 4 with a depressed crescent on posterior half. Tergite 5 with strong lateral setae in male. Sternites heavily sclerotized and covered with microtomentum in male, weakly sclerotized in female.

Male postabdomen: Sternite 5 with lateral sides curved, narrow posteriorly ( Fig. 179). Surstylus paddleshaped, distal portion subrectangular. Postgonite with anterior lobe broad, subrectangular, posterior lobe thin, rounded apically. Basiphallus not swollen, longer than deep, with very short epiphallus, short unsclerotized preepiphallus. Distiphallus short, with short dorsal spinose tube, long ventral projection. Ejaculatory apodeme thin, about as long as width of basiphallus ( Fig. 178).

Female postabdomen: Tergites 6–7 and sternite 6–7 wider than long, moderately sclerotized medially, with weakly sclerotized lateral patches, covered with microtomentum. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 longer than wide, hourglass-shaped, emarginated anteriorly, covered with microtomentum. Epiproct broad, covered with microtomentum, with 1 pair of setae. Cerci broad. Sclerites of sternite 8 broad, covered with microtomentum, pinched medially. Hypoproct broad, subtriangular, anterior margin shiny, notched medially. Spermathecae barrel-shaped, slightly longer than wide, shallowly invaginated apically, evaginated basally, sclerotized duct about as long as spermathecae.

Type material. Holotype ♂: BRAZIL: São Paulo: Est. Biol. Boracéia, dung pans, 2 Dec 2008, G.F. Gonçalves Miranda, debu00344761 ( MZSP)   . Paratypes: Cipó , 15 Oct 1976, V. Alin (1 ♀, ZMUM)   ; Paraná: Curitiba , Feb 1976, H.S. Telford (1 ♀, USNM)   .

Comments. The species name is derived from the Greek krokidos (woollen nap) + sternon (breast), referring to the microtomentose katepisternum (see also P. psilosternum   ).
