Type material. Holotype female, Antsiranana Province, 08.XI-2007, Amber Mountain forest ; “Baobab track”, 2°29.223’S 49°10.217’E. E. Guilbert coll. MNHN.GoogleMaps 

Diagnosis. Body oblong, pronotum with large paranota bent upwards, posterior process longer than wide, hemelytra with costal area irregularly triseriate, median row with areolae smaller than in inner and outer rows.

Description. Body long, brown with a tumid elevation on hemelytra, body beneath and apex of tarsi darker; legs, antennae and cephalic spines yellowish; dorsum densely pilose. Female (N=1): body length, 4.60; width, 1.90.

Head densely pilose, armed with five spines, occipital pair and median spine stout at base and slender at apex, directed forward, occipital spines slightly longer than median spine; frontal pair of spines shorter and slender, converging and directed forward; bucculae three areolae wide, joined in front; rostrum short, reaching middle of mesosternum; antennae long, slender and pilose, antennal segment measurements: I, 0.25; II, 0.18; III, 1.63; IV, 0.50.

Pronotum longer than wide, swollen, deeply punctate, tricarinate, carina raised, uniseriate, median carina higher than lateral carinae, collar two areolae wide, raised to form a small, tectiform hood contiguous to median carina; paranota well developed opposite to humeral angles, six areolae wide, raised, much narrower anteriorly, there one areolae wide, outer margins with tiny denticles; pro- and mesonotal sulcus narrow, metanotal sulcus widened and heart-shaped, open behind.

Hemelytra long, constricted behind apex of discoidal area, expanding at base; costal area broad, raised, two to three areolae wide, areolae irregularly arranged, outer margins with tiny denticles; subcostal area narrower than costal area, regularly uniseriate, areolae large and subquadrate; discoidal area longer than half the length of hemelytra, four areolae wide, areolae smaller than on costal and subcostal area; RM vein sharply raised at the middle length of discoidal area, raised however less at its junction with Cu vein; sutural area six areolae wide, areolae larger posteriorly; hypocostal area uniseriate, narrow anteriorly, widening posteriorly.

Etymology. The name of this species refers to the Anstiranana Province where it was collected.

Comments. This species differs from H. decoris Duarte Rodrigues  having a costal area three to four areolae wide, narrowing to two areolae wide on subcostal area near swollen part. It also differs from H. crispus (Drake)  and H. heranus (Drake)  by the costal area four to five areolae wide in H. crispus  and five to six in H. heranus  ) and by the subcostal area also smaller than the one of H. heranus  (two areolae wide).

The genus Haedacanthus  was described by Duarte Rodrigues (1992) to accommodate Pogonostyla crispa ( Drake 1958)  P. herana ( Drake 1958)  , and H. decoris Duarte Rodrigues 1992  . The genus is endemic to Madagascar.
