Description made from all three specimens but none mounted dorsoventrally and exact layout of some structures uncertain. Mounted material. Body roundly pear-shaped, 1.2–1.5 mm long, and 0.9–1.55 mm wide. Dorsum. Eight-shaped pore structure distinctive, with the two halves joined on one side; of 3 or 4 sizes: (i) largest pore, each 13–15 x 8–9 µm, frequent in a fairly broad marginal band and in 3 broad transverse bands, 1 band approximately dorsad to anterior spiracles, 1 dorsad to posterior spiracles and a third band on anterior abdominal segments plus a median longitudinal band anteriorly; (ii) intermediate pores variable in size, larger pores each about 10 x 6.5 µm, mainly found near type (i) pores, and smaller intermediate-sized pores, each 8.0–8.5 x 5.0–5.5 µm, about as abundant as largest pores, present elsewhere on dorsum apart from medially on posterior abdominal segments, where replaced by (iii) smallest pores, each 6 x 3.0–3.5 µm, present on posterior abdominal segments; intermediate and smallest pores not intermingling with largest pores; with 2 or 3 small intermediate-sized pores associated with apex of each stigmatic pore band. Simple pores, each 2.0–2.5 µm wide, rare. Cribriform plates misshappen, small, each mainly 13–15 µm wide, in 2 groups of 4 or 5 submedially on each side of abdominal segment IV; each plate with a broad border and moderate-sized micropores. Dorsal setae showing nothing distinctive. Tubular ducts with each outer ductule 20–22 µm long and about 2.5 µm wide, slightly broader than those on venter; abundant throughout. Anal lobes mainly membranous, but with sclerotized inner margins; each lobe with a long apical seta, all broken but at least 140 µm long; fleshy seta on dorsal surface near apex short, each 13–15 µm long; fleshy seta near centre of each dorsal surface 20–25 µm long; ventral setose seta near apical setae each 12–14 µm long; medioventral or outer margin setae each about 7 µm long; each lobe possibly without 8- shaped pores. Median anal plate blunt, 33–35 µm long, 33–35 µm wide at base. Anal ring with 4 pairs of setae, each about 50 µm long. Venter. Eight-shaped pores similar to intermediate-sized pores on dorsum, each 10 x 5.5 µm, in a sparse, fairly broad submarginal band; transverse bands anterior to each band of multilocular disc-pores very sparse or even absent. Simple pores rare. Small bilocular pores, each about 4.0 x 4.5 µm, frequent medially on head and thorax, not extending onto anterior abdominal segments. Spiracular disc-pores small, each 4–5 µm wide (smallest near spiracles), mainly with 5 loculi, each band narrow near spiracles but broadening on dorsum; posterior bands bifurcated; each band with 70–80 pores + 2 or 3 intermediate-sized 8-shaped pores associated with apex of each band; also with 1 quinquelocular disc-pore near each antenna. Small convex closed pores, each 3–5 µm wide, present in a broad band between anterior and posterior leg stubs, each band with 45–60 pores. Multilocular discpores, each 6–7 µm wide with mainly 10 loculi, in sparse transverse bands mainly 1 pore wide across abdominal segments, as follows: abdominal segment VIII 0; VII 0 or 1 on each side submarginally, none medially; VI a line of 6–9 medially; V 1–5 submarginally + 9–14 medially; IV 1–4 submarginally + 11–25 medially; III 4–8 submarginally + 18 or 20 medially; II 6–11 submarginally + 11 or 12 medially; also with 0–2 laterad to each leg stub on metathorax but none medially. Tubular ducts slightly narrower than those on dorsum, abundant throughout. Ventral setae showing nothing significant; preanal setae each 55–60 µm long; companion setae short. Leg stubs well developed. Antennae unsegmented, each 31–40 µm long, 23–27 µm wide, without either a sclerotized conelike point or a deep setal cavity; with about 7 or 8 setae. Clypeolabral shield about 125 µm long. Spiracular peritremes each 26–27 µm wide. Comment . The above description is similar to that of Lambdin and Kosztarab (1977) except that (i) they considered the convex closed pores on the venter to be multilocular disc-pores, and (ii) they found only two sizes of 8-shaped pores on the dorsum. Adult females of A. madagascariensis are somewhat similar to A. theydoni and A. yemenicus in having a broad band of small convex closed pores but these pores are much more abundant in the current species, on which they also form a group laterad to each metathoracic leg stub. Adult females of A. madagascariensis also have the following combination of character-states: (i) dorsum with three or four sizes of 8-shaped pores; (ii) largest 8- shaped pores restricted to margin and three broad transverse bands; (iii) largest 8-shaped pores absent from margins of posterior abdominal segments; (iv) smallest 8-shaped pores restricted to medially on posterior abdominal segments; (v) intermediate-sized 8-shaped pores present elsewhere but not intermingling with largest or smallest pores; (vi) cribriform plates in a submedial group of four or five on each side of abdominal segment IV; (vii) leg stubs present; (viii) posterior disc-pore band bifurcated; (ix) multilocular disc-pores sparse, in transverse bands across abdominal segments II–VI and laterad to metathoracic leg stubs; (x) small convex closed pores present in a band between pro- and metathoracic leg stubs; and (xi) antennae without a cone-like apex and setal cavity. The adult female of A. madagascariensis falls within Group D in the key to species of Antecerococcus , and keys out close to A. theydoni and A. yemenicus .
