( Fig. 10 View FIGURE 10 )

Cerococcus cistarum Balachowsky 1927: 202–204   ; 1930: 207–210, 215.

Type details. ALGERIA, nr. Alger, Kouba, on Cistus heterophyllus   ( Cistaceae   ), 18.xii. 1926, A. Balachowsky. Depositories: MNHN: l ectotype adf (here designated —see note below) and paralectotype adf (lectotype marked by an arrow) on 1 slide (MNHN 4854); paralectotype ff: same data as lectotype, 1 / 1 adf (MNHN 4854); same data as lectotype but 18.xii.1926, 3/ 6 adff (MNHN 4855 - 1 (2 adff), 4855 - 2 (2 adff) and 4855 - 3 (2 adff)). BMNH: ALGERIA, Constantine, El Guerrah, on Fumania glutinosa   (in Balachowsky, 1927) (= Helianthemum glutinosum   (in Lambdin & Kosztarab, 1977 )) ( Cistaceae   ), no date, A. Balachowsky # 6: 1 / 4 paralectotype adff (fvp). USNM: ALGERIA, Alger, Koula (should be Kouba), on Helianthemum glutinosum   , -. xii. 1926, A. Balachowsky: 1 / 1 paralectotype adf (Miller, pers. comm.).

Note. Although Miller et al. (2005) indicate that there is a holotype in Insectarium Jardin d’Essai in Algeria and Lambdin and Kosztarab (1977) mention paratypes, Balachowsky left no slides in Algeria, returning from Algeria with all his collection including types (Danièle Matile, pers. comm.). In fact, Balachowsky (1930, p. 210) states clearly that the type is in “Station centrale Entomology de Paris” [the collection is now the MNHN] but, as none of the type series was marked as “ type ” by Balachowsky, a specimen has been designated lectotype above. The correct spelling of the collection site is Kouba.

Material studied. Paralectotypes: ALGERIA, Constantine, El Guerrah, on Fumaria glutinosa   (in Balachowsky, 1927) (= Helianthemum glutinosum   (in Lambdin & Kosztarab, 1977 )) ( Cistaceae   ), no date, A. Balachowsky # 6 (BMNH): 1 / 4 adff (f-vp). Also: CYPRUS, Kyrenia, 30.xii. 1931, on Cistus   sp. ( Cistaceae   ), E.E. Green (BMNH # 44 / 53): 2 / 5 adff (f).

Mounted material. Body slightly elongate pear-shaped, 1.0– 1.3 mm long, 0.8 –1.0 mm wide.

Dorsum. Eight-shaped pores of 2 sizes: (i) a variable medium-sized pore, each 9–13 x 5.0– 7.5 µm, some with slightly pointed ends, each 14 x 7.5 µm, and some near each stigmatic pore band with smaller inner pale areas; present sparsely throughout, including posterior abdominal segments; perhaps most abundant nearer margins; and (ii) smaller pores, each 6.5 –7.0 x 4.0 µm, occasionally present on anal lobes and anterior to anal plates; small pores absent from apices of stigmatic pore bands. Simple pores very sparse throughout, each 1.5 –2.0 µm wide. Cribriform plates large, each 16–35 µm wide, with a fairly narrow sclerotized margin and moderate-sized micropores; in submedial groups of 3 plates on each side of segment IV, although larger plates are probably 2 or more fused. Dorsal setae few, each setose and mainly about 5 µm long. Tubular ducts with each outer duct 20–22 µm long, mostly 2.0– 2.5 µm wide (about same width as on venter). Anal lobes membranous apart from inner margin which is distinctly sclerotized; each lobe 55–65 µm long, with a long apical seta, both broken; each posterior fleshy seta on dorsal surface short and bent, 15–20 µm long; more anterior fleshy setae longer, each 24– 27 µm long; ventral seta near apex setose, 25–35 µm long; medioventral setae quite long, each 23–27 µm long; outer margin seta apparently absent; each lobe with 0–3 small 8 -shaped pores. Median anal plate roundly triangular, 38–50 µm long, 40–56 µm wide at base. Anal ring with 4 pairs of setae, each about 75 µm long.

Venter. Eight-shaped pores similar to larger pores on dorsum, each 12 x 6.5 µm, present in a submarginal band around margin of head and thorax and sparsely in transverse bands on abdominal segments; also forming a sparse line or band along lateral margins of posterior abdominal segments. Simple pore similar to those on dorsum but very sparse. Small bilocular pores, each 5.0– 5.5 µm widest, frequent medially on head and thorax. Spiracular discpores small, each 4–5 µm wide, mainly with 5 loculi near each spiracle but becoming multilocular (mainly with 8 loculi) near apex of each band; in a fairly dense group of about 15 pores near each spiracle, then forming a sparse band but this becoming dense on dorsal surface near apex; posterior band bifurcated; anterior and both posterior bands each with about 55 pores; each apex without associated minute eight-shaped pores; also with one 5 -locular pore near each antenna. Small convex closed pores not detected. Multilocular disc-pores, each 6–7 µm wide, mainly with 10 loculi, distributed as follows: abdominal segment VIII with 1–3 on each side, VII 4–6 on each side; and then in narrow transverse bands mainly 1 pore wide: VI 2–5 submarginally + 14–18 medially; V 2–4 submarginally + 19–24 medially; IV 2–5 submarginally + 17–24 medially; III 1–5 submarginally + 20–23 more medially, II 2–4 submarginally + 0–7 medially; also with 1 or 2 on each side of metathorax but absent medially none found near spiracles. Tubular ducts very similar to those on dorsum, present throughout. Ventral setae slightly more abundant than on dorsum on posterior abdominal segments but all setose and short; preanal setae each 75 µm long; companion setae short. Leg stubs absent. Antennae unsegmented, each 30–35 µm wide, with 7 or 8 setose and fleshy setae; without either an apical cone-like spine or a distinct setal cavity. Clypeolabral shield 125–145 µm long. Spiracular peritremes each about 25 µm wide.

Comment. The above description is similar to that of Lambdin and Kosztarab (1977). The adult female of A.

cistarum   is distinctive in having: (i) dorsum with two intermediate-sized 8 -shaped pores: (ii) intermediate-sized pores frequent throughout; smaller pores only present near anal lobes, (iii) large 8 -shaped pores entirely absent; (iv) median anal plate triangular; (v) cribriform plates in a submedial group of three plates on each side of abdominal segment IV; (vi) leg stubs absent; (vii) posterior stigmatic bands bifurcated; (viii) multilocular disc-pores in a line one pore wide, across all abdominal segments, each with few pores; (ix) each stigmatic pore band forming a small oval group dorsally, without small eight-shaped pores, and (x) antennae without either a setal cavity or a cone-like extension

The adult female of A. cistarum   falls within Group D in the key to species of Antecerococcus   , and is possibly most similar to A. laniger   .
