Scale bars: 1 mm. Females (n = 4, except antennal segments III and IV (n = 3); median (minimum–maximum)). Body length 13.77 (13.69–15.08); head: length 3.72 (3.68–3.72), width (including eyes) 4.07 (4.02–4.17), interocular width 3.04 (2.99–3.19); lengths of antennal segments: I – 0.78 (0.74–0.78), IIa – 0.98 (0.88–1.03), IIb – 1.01 (0.98–1.03), III – 1.27 (1.27–1.37), IV – 1.42 (1.37–1.47); pronotum: length 3.75 (3.68–3.97), width 11.42 (11.18–11.57); scutellum: length 6.96 (6.86–7.06), width 6.47; abdomen: width (across segment III) 11.47 (11.27–12.06). Intraspecific variation. The specimens examined appear uniform in structure (except slight differences in measurements) and differ mostly in details of the black markings on the body venter and the antennal segment I. Only in some specimens from the environs of Antananarivo the venter of abdomen is more or less bright red. Etymology. The species name is the Latin adjective undulatus (- a , - um ), meaning wavy, waved, undulate, referring to the characteristic undulated lateral margins of abdomen. Habitat and biology. Unknown. Distribution. Humid and subhumid forest areas of north-eastern and eastern Madagascar (Fig. 74).
