Poecilantrops boraceiensis View in CoL sp. nov.

( Figs. 177, 180 View FIGURES 173–180 , 235 View FIGURES 231–239 )

Description. Head reddish brown, anterior margin of frons and antenna orange, prementum and maxillary palp yellow. Orbital plates, most of frontal triangle (except adjacent to ocellar triangle), bases of interfrontal setae, and occiput covered with microtomentum, face with small patch of microtomentum below lunule, gena with microtomentum on ventral two-thirds. Ocellar bristles just anterior to median ocellus. One subvibrissal and anterior genal bristle enlarged, about 0.5X length of vibrissa.

Thorax black, with extensive microtomenutm. Proepisternum, ventral third of anepisternum, anterior half of katepisternum, meron and metapleuron except stripe between posterior spiracle and hind coxa shiny. Halter white. Acrostichal bristles in about 6 rows.

Fore leg with coxa, trochanter, and femur orange, tibia and basal 2 tarsomeres dark brown, distal 3 tarsomeres whitish. Mid leg orange, coxa black, basal two-thirds of femur dark brown. Hind leg orange, coxa black, basal twothirds of femur black, distal half of tibia brown. Mid tibia with anterior row of anterodorsal, 1 anteroventral, 1 posteroventral, 5 subapical bristles. Hind tibia with 2 ventroapicals, length of longest about 1.5X 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 distal to dm-cu and 1 at tip, 1 on vein CuA 1 basal to dm-cu.

Abdominal tergites black, covered with microtomentum. Tergite 3 fused to tergite 2. Anterior margin of tergite 4 irregularly excavated. Syntergite 1+2 with a median ridge. Sternites heavily sclerotized, black, covered with microtomentum in male, weakly sclerotized in female.

Male postabdomen: Sternite 5 parallel-sided, with posterior margin broadly excavated, two very narrow, divergent apodemes ( Fig. 180 View FIGURES 173–180 ). Surstylus very broad, portion projecting below cerci with a quarter-circle shape, posterior margin straight. Pregonite distinct. Postgonite with very broad, rounded anterior lobe, narrow, pointed posterior lobe. Basiphallus swollen, without distinct epiphallus, preepiphallus short, curved. Distiphallus with a thin, smooth dorsal tube flanked by a single spike-like sclerite ( Fig. 177 View FIGURES 173–180 ).

Female postabdomen: Tergites 6–7 very broad, tergite 6 weakly sclerotized, tergite 7 heavily sclerotized except lateral edges, both covered with microtomentum. Sternite 6–7 weakly sclerotized along anterior and posterior margins only. Tergites with very weakly sclerotized posterior strips, sternites without visible strips. Tergite 8 broad, lateral margins rounded, anterior margin broadly emarginated, anterior margin shiny. Epiproct with distal half covered with microtomentum, 1 pair of setae. Sclerites of sternite 8 weakly sclerotized, anterior portion narrow, shiny, distal portion broad, covered with microtomentum. Hypoproct lozenge-shaped, weakly sclerotized. Spermathecae relatively large, round, not invaginated.

Type material. Holotype ♂: BRAZIL: São Paulo: USP Biology Station , 5–6 Feb 1979, R. Woodruff & J. Runnacles, debu01039073 ( MZSP) . Paratypes: same data as holotype (1 ♂, 3 ♀, DEBU, MZSP) ; Boracéia , 1 Feb 1994, M. Carrera (1 ♀, MZSP) ; as above but 850 m, 22–25 Jul 1949, L. Trav. F. & E.X. Rabello (1 ♀, MZSP) ; Est. Biol. Boracéia , dung pans, 2 Dec 2008, G.F. Gonçalves Miranda (2 ♀, MZSP) ; Rio de Janeiro: Rio de Janeiro , 1 Apr 1938, [no collector] (1 ♂, USNM) .

Comments. The species name refers to the Boracéia Biological Station, where this and several other members of Poecilantrops have been collected. This species is fairly similar to A. crocidosternum sp. nov. and A. psilosternum sp. nov.; all three can be readily separated based on the extent of microtomentum on the katepisternum, as well as the other characters given in the key.
