Poecilantrops plaumanni View in CoL sp. nov.

( Figs. 184, 188 View FIGURES 181–188 , 235 View FIGURES 231–239 )

Description. Head dark reddish brown, occiput black, antenna orange. Mostly covered with microtomentum, shiny on interfrontal plates, reaching to lateral ocelli medially, and ventral triangle on face. 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, mostly covered with microtomentum, anepisternum with a rectangular ventromedial shiny spot, katepisternum with spot behind fore coxa, metapleuron shiny except stripe between posterior spiracle and hind coxa. Halter whitish, brown below knob. Acrostichal bristles in about 6 rows.

Legs black, trochanters and tarsi yellow except first and hind basotarsomeres brown. Mid tibia with row of anterodorsal, 1 anteroventral, 1 posteroventral, 5 subapical bristles. Hind tibia with 2 ventroapical bristles, longest about as long as width of tibia.

Wing brown, whitish at junctions of veins, spots on crossveins r-m and dm-cu, at tips of veins R 2+3 and R 4+5, 1 on vein R 4+5 basal to r-m and 2 distal to r-m, and on vein CuA 1.

Abdomen with tergites black, covered with microtomentum, heavily sclerotized. Sternites square, black, covered with microtomentum, and heavily sclerotized in male, weakly sclerotized in female. Strong lateral setae on tergites 3–4 in male. Tergite 5 with a small depression medially on posteromedial margin.

Male postabdomen: Sternite 5 square, with slightly projecting paired medial lobes on posterior margin ( Fig. 188 View FIGURES 181–188 ). Surstylus expanded distally, ventral margin pointed, medial margin notched. Postgonite with posterior lobe very short, anterior lobe very broad, rectangular. Basiphallus slightly longer than wide, no distinct epiphallus, preepiphallus short, transparent. Distiphallus with a short smooth dorsal tube, flattened flanking spines ( Fig. 184 View FIGURES 181–188 ).

Female postabdomen: Tergites 6–7 wider than long, entirely sclerotized, with 3 weakly sclerotized posterior strips, lateral margins indented. Tergite 8 with lateral and anterior margins indented, covered with microtomentum. Epiproct narrow, parallel sided, with short anterior arms, 2 setae. Cerci covered with microtomentum. Sternites 6–7 wider than long, entirely sclerotized, with weakly sclerotized posterior strips. Sclerites of sternite 8 narrow anteriorly, covered with microtomentum. Hypoproct ovoid, anterolateral portions shiny. Spermathecae 2X longer than wide, annulated, without sclerotized ducts.

Type material. Holotype ♂: BRAZIL: Santa Catarina: Nova Teutônia , 27°10'S 52°22'W, 300–500 m, Mar 1972, F. Plaumann, debu01039284 ( FMNH) GoogleMaps . Paratypes: same data as holotype but Sep 1964 (1 ♀, DEBU) GoogleMaps ; as above but May 1967 (1 ♂, CNCI) ; as above but Sep 1972 (3 ♀, FMNH) ; as above but Oct 1972 (1 ♂, 8 ♀, FMNH) ; as above but Aug 1978 (2 ♂, 3 ♀, FMNH) ; as above but Nov 1978 (2 ♀, FMNH) ; São Paulo: Barueri, 18 Nov 1955, K. Lenko (1 ♂, MZSP) .

Comments. This species is named in recognition of the remarkable collecting effort and skill of the late Fritz Plaumann, who collected most of the type series of P. plaumanni , as well as a significant number of other specimens of Brazilian Archiborborinae . The black femora are unlike other known Brazilian Poecilantrops .
