Redescription. Color: Body generally pale, orange with black markings ( Fig. 1 ). Head black with pale collar on neck. All antennal segments dark brown, basiflagellomere and distiflagellomere slightly paler. Intercalar segments slightly paler than other antennal segments. Pronotum, scutellum orange. First and second visible labial segments black. Third visible labial segment and apical part of second segment pale. Hemelytra orange (more intensive color than in pronotum) with black markings apically on corium (extended on membrana) over VI abdominal tergite. From VI abdominal tergite basal and lateral margins of membrane dark. Venation on membrane grayish-brown. Legs bicolorous. Femora orange with black apically. Tibiae black. Fore and middle tarsi dark with pale first segment and basal part of second segment. Hind tibiae with pale first, second, and a basal part of third segment. Mediotergite, dorsal and ventral laterotergites and lateral margins of sternite of VI abdominal segment black. Abdomen orange in both sexes.

Structure: Body medium-sized, shining and slender in both sexes. Head with only a few medium-sized setae in postocellar and apical part as well as on antennifers. Anteocular part of head as long as postocular part. First and second visible labial segments with rather short, erected, and curved setae. Third visible labial segment with short, erected setae. Second visible labial segment reaching over posterior margin of the head. Scapus with various sized, scarce, erected setae. Pedicellus with very dense, erected setae. Basiflagellomere and distiflagellomere with dense, adherent setae. Anterior pronotal lobe with longitudinal sutura barely visible in apical part and distinctly hollowed basally. Anterior lobe with distinct calli in apical part. Both lateral parts (almost quadrangular in shape) of anterior pronotal lobe delicately curved in part connected with transversal sutura of pronotum. Posterior pronotal lobe with delicate depression in the middle and with long setae on the margins. Posterolateral angles of pronotum distinctly surpassing beyond posterior margin of pronotum. Scutellum with long, dense setae. Trochanters, femora, and tibiae with long setae. Hemelytra slender, surpassing apex of abdomen. Corium shining with medium, dense, and curved setae in basal part. Connexiva with slightly rounded external margin. Ventral part of abdomen with medium setae.

Genitalia: Male—Median process of pygophore long, wide, with two small processes (left slightly bigger) placed laterally on apex ( Figs 6–8 ). Apical part of middle process rounded. Both parameres club-shaped, distinctly curved with long setae on outer side ( Figs 9, 10, 13, 14 ). Both parameres with rounded apices. Phallosoma short and thin ( Figs 15, 16 ). Dorsal phallothecal sclerite enlarged with two sharp apices (directed laterally in dorsal view) in apical part ( Figs 11, 15 ). Phallus flattened ( Figs 13 ; 16; 17).

Female—Valvifer and valvula 1 quadrangular with long hairs on outer side and elongated processes with rounded on apex ( Figs 4, 5 ). Valvula 3 club-shaped and thin apically ( Fig. 3 ).

Measurements (in mm, male in parentheses): Body length: 11.25–12 (10.5–11.1); maximum width of abdomen: 3.42–3.75 (2.6–3.16); head length: 1.75–1.83 (1.5–1.7); head width: 1.33–1.41 (1.33–1.42); length of anteocular part: 0.41–0.54 (0.42–0.6); length of postocular part: 0.67–0.75 (0.5); length of synthlipsis: 0.63–0.67 (0.58–0.67); interocellar distance: 0.25–0.33 (0.25–0.33); length of antennal segments I:II:III:IV: 2.08–2.3 (2.42– 2.59): 0.81–0.83 (0.92–1.08): 1.33–1.58 (1.8–2.5): 2.25–2.33 (0.75–1.3); length of labial segments I:II:III: 0.79– 0.83 (0.83–.0.92): 0.96–1.08 (0.92–1): 0.29–0.33 (0.29–0.33); maximum length of anterior pronotal lobe: 0.75– 0.83 (0.67–0.75); maximum length of posterior pronotal lobe: 1.67–1.83 (1.3–1.58); maximum width of anterior pronotal lobe: 1.33–1.5 (1.16–1.33); maximum width of posterior pronotal lobe: 3–3.25 (2.5–2.67); length of scutellum: 0.58–0.83 (0.58–0.67); length of hemelytra: 8.1–8.5 (7.1–7.25).

Distribution. Madagascar.

Comments. During dissection of the female genitalia, a few eggs inside were found. The drawing of an egg is given in Fig. 2 .
