Large species; face ivory white; head white and black, mesosoma testaceous-orange, metasoma black with apical margin of tergites 2–7 white; face densely punctate, clypeus transverse and sparsely punctate; entire mesosoma densely punctate-granulate; area superomedia about 2.5 x longer than wide; female femoral tooth small; ovipositor moderately long, its apex sinuate; POL 0.6; OOL 0.7; CT 1.9; ML 0.6; OT 1.4-1.5; FFT 1.
Species characterized by the black and white color pattern of metasoma, and the entirely densely punctate-granulate mesosoma.
Refers to a great beer of similar color pattern.

MADAGASCAR: 11♀♀, 1♂ ( MNHN), Rogez, February 1930 and 1936, January, April–May 1932, 1935, May 1936 and 1938; 1♂ ( MNHN), Ivondro, March 1940.
LENGTH. 6.5, 5.9 (4.9–6.7) (10 specimens).
HEAD. Strongly constricted behind eyes. Temple very short. Vertex finely granulate and sparsely punctate. Ocellar triangle equilateral. Frons smooth with basal transverse striation and a distinct longitudinal ridge from the central ocellus. Face subrectangular, shining, more densely punctate centrally than laterally. Clypeus moderately transverse, smooth with sparse punctures. Mandible stout, teeth subequal. Malar line rather short. Antenna with 35–36 flagellomeres.
MESOSOMA. Moderately elongate, nearly 2 x longer than high. Pronotum, mesonotum, mesopleuron and metapleuron densely punctate-granulate. Speculum punctate with a narrow smooth ventral area. Notaulus strongly impressed. Propodeum long, densely punctate, area petiolaris transversally wrinkled, area basalis opposite or slightly truncate, area superomedia about 2.5 x longer than wide, about as long as area petiolaris. Legs: femoral tooth reduced but distinct, followed by a row of small tubercles.
METASOMA. Tergite 1 almost smooth, post-petiole and tergite 2 finely aciculate, the following tergites finely granulate. Tergite 2, about 0.7 x as long as tergite 1, about 2.5 x longer than apically wide. Ovipositor moderately long and sinuate at apex.
COLOR. Head ivory white with frons, vertex, temple, occiput, posterior half of gena, and a small triangle under toruli black. Antenna basally black, fading to testaceous from flagellomere 3 but two apical flagellomeres darker. Mesosoma and legs testaceous orange. Metasoma black, tergites 2 and following largely white apically. Wings hyaline, densely hairy, pterostigma dark brown.
Length: 6.7 (6.3–7.1) (2 specimens). Posterior ocellus almost touching eyes dorsally (OOL = 0.1; POL = 0.4). Hind femur swollen with a stout and pointed tooth, followed by a row of denticles. Otherwise similar to female.
