Matile, pers. comm.) nor in the USNM. Therefore a lectotype has been chosen from among the syntypes in MNHN and is designated here. FIGURE 21. Antecerococcus intermedius (Balachowsky) . Adult female.

Eight-shaped pores of 3 sizes: (i) largest pores, each 20–22 x 13 [20– 22 x 12–13 / 20 x 11 ] µm, in medial swirls and in about 5 radial bands, and with concentrations around each stigmatic pore band; also with 7–10 [7–11/6–8] on each side of posterior abdominal segments; (ii) intermediate-sized pores, each 11–12 x 4–6 [ 9–11 x 5.5–6.0/7– 9 x 3.5–5.0] µm, throughout rest of dorsum wherever larger pores absent but becoming smaller on posterior abdominal segments [7.5 x 4.0/7.5 x 5.0]; also in swirls medially; and (iii) minute pores, each 5 x 3 [ 5 x 3.0–3.5/5.5 x 3.0] µm, restricted to 1–4 in each apical group of stigmatic pore bands. Simple pores small, each 2.0– 2.5 µm wide, sparse. Cribriform plates in a submedial group of 2–4 [3–5/3–5] on each side of abdominal segment IV, each unevenly round and 16–21 [13–22/13–22] µm wide; each with a broad margin and medium-sized micropores, often with 2 or 3 fused together. Dorsal setae few, each setose, showing nothing distinctive. Tubular ducts with each outer ductule 24–25 µm long, inner ductules quite short; outer ductules broader than those on venter; abundant throughout. Anal lobes with quite broad areas of sclerotization on each inner margin, without obvious folding; setae as follows: apical seta each about 250 [at least 190–230/at least 215] µm long; dorsal fleshy setae somewhat bent; more basal setae 35–40 [38–45/30–35] µm long, more apical setae 33–40 [40–45/26–32] µm long; setose setae near apex on ventral surface 38–50 [35–45/33–35] µm long; medioventral setae long, each 25 [15–20/13–15] µm long; anteroventral setae absent; outer margin setae each 17–18 [15–20/15–18] µm long; each lobe with a few small 8-shaped pores. Median anal plate bluntly rounded, sometimes with serrations; 43–55 [25– 35/30–35] µm long, 50 [60–62/45–48] µm wide at base. Anal ring with 4 pairs of setae, each 90–115 [80–90/115] µm long. Venter. Eight–shaped pores of intermediate size, approximately same size as those on dorsum but more rounded, each 12–13 x 6.0–6.5 [ 13–15 x 6.5–7.0/ 13 x 7 ] µm, in a marginal band on head and thorax and in segmental bands several pores wide across anterior abdominal segments; pores nearest stigmatic pore bands largest. Simple pores sparse. Small bilocular pores roundish, each 5 x 4 [ 5 x 3/ 6 x 4.5] µm, frequent medially on head and thorax. Spiracular disc-pores each 4–5 [3–4/5–6] µm wide, with mainly 5 loculi; with only a small group [8–15] near each peritreme; stigmatic pore bands mainly 1–3 pores wide [2–5 pores wide in C. cycliger ]; anterior band with a total of 39–53 [40–60/60–80] pores; posterior bands bifurcated, each with 30–50 [30–50/50–70] pores; each band with 0–2 [0–2/1–4] minute 8-shaped pores associated with apex; also with 1 or 2 [1–3/1–6] 5-locular pores laterad to each antenna. Small convex closed pores absent. Multilocular disc-pores, each 6.5–7.5 µm wide, mainly with 10 loculi, in transverse bands on each abdominal segment, as follows: IX 0; VIII with 1–5 on each side; VII 6–14 [4–9/4–7] in a submarginal group on each side of vulva; VI 7–10 [3–7/4–7] submarginally + 47–68 [20–36/31–37] medially; V 13–19 [7–10/6–12] submarginally + 63–76 [35–45/56–58] medially, in a band 2–4 pores wide; IV 13–22 [7–11/10–14] submarginally + 72–89 [32–42/64 or 65] medially, in a band 2–4 pores wide; III 4–6 [3–8/8–11] submarginally + 48–57 [9–16/44 medially], in a line 1 pore wide, and II 1–5 [0–7/7–19] submarginally +10–17 [6–8/29–32] medially; metathorax with 1–4 [0–7/10–16] submarginally, none medially. Tubular ducts very slightly narrower than those on dorsum, present throughout. Ventral setae showing nothing distinctive; preanal setae each 90–100 [65–80/about 100] µm long; smaller companion seta 12 [13/12] µm long. Leg stubs absent. Antennae unsegmented, each 50–55 [30–55/26] µm long, 35–40 [26–50/28] µm wide, with 6–8 fleshy setae; each antenna rounded, without either an apical cone-shaped point or a setal cavity. Clypeolabral shield 145 [150–155/180] long. Spiracular peritremes each about 33–40 [25–28/33–40] µm wide. Comment . The above description is very similar to that of Lambdin and Kosztarab (1977) for C. intermedius . The adult female of A. intermedius belongs to the Antecerococcus group with abundant large 8-shaped pores over much of the dorsum and has the following combination of character-states: (i) dorsum with three sizes of 8- shaped pore, largest in radial bands and medial swirls, intermediate-sized pores throughout; minute pores restricted to stigmatic pore bands; (ii) posterior abdominal segments with 6–10 large 8-shaped pores along each dorsal margin; (iii) cribriform plates roundish, with 2–4 submedially on each side of abdominal segment IV; (iv) leg stubs absent; (v) posterior stigmatic pore bands bifurcated; (vi) multilocular disc-pores in seven fairly broad transverse bands across abdominal segments and submarginally on metathorax; (vii) fleshy setae on dorsal surface of each anal lobe long; (viii) medioventral setae on each anal lobe long but anteroventral setae absent, and (ix) antennae without either an apical cone-shaped spine or an obvious setal cavity. As indicated by Neves (1954), the adult female of C. camarai is very similar to that of C. intermedius Balachowsky. Both species were collected on Lamiaceae and no significant differences could be found between the two lots of material, although the multilocular disc-pores on C. camarai were between one half to a third fewer than on A. intermedius . On the other hand, these pores were slightly more frequent on C. cycliger . It is here considered that the small differences noted above relate to geographical variation and therefore the names C. camarai Neves and C. cycliger Goux are here considered to be junior synonyms of C. intermedius Balachowsky. The differences between the specimens illustrated in Figs 21–23 are considered to be natural variation due to age and environmental factors. The adult female of A. intermedius falls within Group D in the key to species of Antecerococcus , keying out closest to A. delottoi from Kenya and A. perowskiae from the Palaearctic.
