Description made mainly from typeseries. Some data for some of the other material is given in Table 3and in (..) brackets below.   Unmounted material."Test of the adult female highly convex; the dome with a shallow median depression with a very small elongate boss, longitudinally orientated, pushed anteriorly by the cone of wax behind it. Plates only obscurely marked on the adult but more clearly on the young specimens. Diameter of the wax of the adult female up to 8 mm. With the wax removed, the adult female is highly convex, with 3 very small lateral processes, plus 1 cephalic and another dorsal; the caudal process is small and directed upwards at an angle of about forty-five degrees." ( Hodgson, 1969a: 4).   Mounted material.Body probably rather roundly oval and convex, with shallow stigmatic clefts; dorsum with distinct lateral tubercles. Caudal process short. Body length 2.5–3.5 mm, total width 1.5–2.75 mm.   Dorsum.Derm membranous except for heavily sclerotised caudal process, becoming more sclerotised on older individuals; caudal process 0.5–0.85 mmlong, 0.54–0.83 mmwide. Derm apparently with 8 clear areas, anterior and medio-dorsal areas with dorsal setae. Dorsal setae each very blunt, often appearing cylindrical, each subequal to or slightly longer than width of basal socket, each seta 4–5 µm long and socket 4–5 µm wide; present sparsely throughout but absent in clear areas. Dorsal pores: (i) loculate microducts of rusci-type abundant, each about 5–7 µm widest; pores with 2 or 3 satellite loculi much less frequent and most abundant in wax-plate lines but occasional elsewhere; pores abundant throughout but absent from clear areas; and (ii) simple microducts present sparsely in all clear areas but very scarce or absent elsewhere. Preopercular pores present in a single line of 4–10. Anal plates each 150–165 µm long, width of both plates 145–165 µm, each with 3 (possibly sometimes 4) strong dorsal setae, each perhaps 65–75 µm long plus a shorter subapical seta. Anal tube short, about as long as anal plates; anal ring setae each about 200 µm long.   Margin.Marginal setae strongly setose; each about 18–22 µm long; with 15–18 (11–20) anteriorly between eyespots, and (on each side) 5–8 (5–9) between eyespots and anterior stigmatic seta, + 0–2 among stigmatic setae; 4–8 between stigmatic setae + 1 or 2 among stigmatic setae both anteriorly and posteriorly, and perhaps 17–19 along either side of abdomen + 1 or 2 anteriorly amongst stigmatic setae; each anal lobe with 3 or 4 long setae, longest about 75–85 µm long. Stigmatic clefts shallow, each with an elongate group of conical stigmatic setae, each seta about as long as wide, with convex sides; each group mainly 3 or 4 setae deep; groups occasionally almost meeting medially between stigmatic areas laterally, and extending an equal distance on each side of cleft; each cleft with 18–25 (18–34) marginal and 12–23 (8–27) non-marginal stigmatic setae (totals per cleft 31–53) (i.e., non-marginal setae extend some distance out of each cleft and are about 2/3rds as abundant as marginal stigmatic setae); smallest spinose seta 6 µm long and 5 µm wide, but generally with 1 incentre of each group larger, each about 17 µm long and 13 µm wide. Eyespots each about 38–40 µm wide.   Venter.Derm entirely membranous. Pregenital disc-pores abundant around genital opening (segment VII) and across preceding segment; also with about 2 medially + a group associated with anogential fold mediolaterally on V; generally absent on segments IV–II and metathorax but occasionally 1 pore present on 1 or more segments. Spiracular disc-pores present in fairly broad bands of about 100–120 pores, each band often widening submarginally; those near each cleft more sclerotised; with none extending medially past peritreme. Ventral microducts showing nothing distinctive. Ventral tubular ducts present both anteriorly and posteriorly, with about 3–10 incephalic region and 1 or 2 mediolaterally associated with anogenital fold in abdominal segments V and/or VI; each with a long narrow inner ductule, often with a terminal gland. Submarginal setae frequent, each 20–25 µm long. Antennae each with 6 segments, segment III with 2 or 3 pseudo-articulations; total length 275–350 µm. Clypeolabral shield about 185 µm long. Spiracles: width of peritremes 68–92 µm. Legs well developed, each with a distinct tibio-tarsal articulation and sclerosis; each claw sometimes with a hint of a denticle; claw digitules both broad and shorter than tarsal digitules; dimensions of metathoracic legs (µm): coxa 145–160; trochanter + femur 175–200; tibia 105–130; tarsus 70–83, and claw 18–25.   Discussion.As pointed out by Hodgson (1969a),  C. eugeniaeis very close to  C. rusciand  C. eucleaebut the latter 2 species differ from  C. eugeniaein having generally fewer stigmatic setae in each cleft, particularly nonmarginal stigmatic setae. In addition, the specimens of  C. ruscifrom north Africa and the Mediterranean have a distinct denticle on each claw, absent on most material from further south. It is possible that  C. castelbrancoiis also a synonym of  C. eugeniae. In this study, what is believed to be  C. eugeniaehas only been seen from Mozambique, Zambiaand Zimbabwe, on  Eugenia owariensisand  Syzygium guineenseand  S. cordatum(Myrtaceae),  Loranthus quequensis(Loranthaceae),  Tecomaria capensis(Bignoniaceae),  Viscum subcylindricum(Viscaceae), and  Pappea capensisvar. radlkoferi(Sapindaceae).  Cryptic or sibling species.In addition to the material studied above, there is a single slide from Malawi (  Malawi, Nyika Plateau,  Ochna puberula, 7.vii.1966, C.J. Hodgson (BMNH): 1/1 (fair, originally identified as  C. spicatus) which is very close to  C. eugeniaein that it has a long line of non-marginal stigmatic setae and the stigmatic setae in each cleft are a long way apart but it has rather few stigmatic setae in total and they are only 2 deep in each cleft. In addition, we also saw the following:  Algeria,Sahara Central, Dider, Tassili N’Ajjero, on Asclepiadaceae, -. iv.1949, A.S. Balachowsky (MNHN #68): 1/1 (poor).  Comoros, Anjouan[ Nzwani], Niouma- Kélé, on  Cananga odorata, 1911, Fleutiaux (MNHN #7489): 2/2 (good-fair).  São Tomé[San Thomé], Monte Café, on coconut, -. iv.1990, A.

A.N. Ritchie (BMNH): 2/3 young adff (fair-poor, as  C. actiniformis).  Uganda, Jinja, on exotic tree, 20.ii.1921, H. Hargreaves (BMNH): 1/ca8 or 9 (fair-good, identified as  C. floridensis).  Democratic Republic of the Congo(as Belgian Congo), Dimonika, rte de Voula Troua, “ind. do carton fourmis”, 14.xi.1975, D. Matile (MNHN #6400): 1/1 (good); Rutshuru, on  Annona muricata, 25.ii.1938, Ghesquière #4219 (MNHN, TERV): 2/5 (good-fair). These specimens appeared to be similar to  C. eugeniaebut, as the collection sites are all a long way from southern Africa, it is here considered that they could represent cryptic or sibling species.   FIGURE 55.  C. eugeniaeHall.Lectotype series. For explanation of labels, see p. 9. Notes: (i) dorsal loculate microducts of ruscitype; (ii) with 11-20+ marginal setae between eyespots; (iii) stigmatic setae extending out of cleft along margin and sometimes meeting between clefts, but sparse between clefts; (iv) stigmatic setae in each cleft mainly 3-4 deep and with dorsal-most seta largest; (v) each cleft with about 18-35 marginal stigmatic setae + 8-23 non-marginal setae (latter extending a long way out of cleft); (vi) multilocular disc-pores usually only present posteriorly on abdomen; (vii) ventral tubular ducts few, present both anteriorly and posteriorly; (viii) tibio-tarsal articulatory sclerosis present, and (ix) claw digitules both broad.   TABLE 3.Comparison of some data from collections of  C. eugeniaeand of two possible cryptic sibling species.    Site No seen Ant.hd set Post hd set Ant marg ss Ant. non- marg. ss Lat.m arg set Post m. ss Post non-m. ss Depth Ant. mldp Hd tub. ducts Den t.  Type 9 15–18 5–8 18–25 12–23 4–8 22–30 13–22 2–4 III–V 3–10 Hint    Loranthus 1 15+ 6 20 15 7 23 15 3 V 8 x–h    Syzygium 1 18 6 24 21 6 29 17 3–4 V 6 x    Viscum 1 20 6 28–34 9–20 6 31 22 4 V ?2 x–h  Mozambique 1 13 9 28 27 4 29 18 4 ? 10 x  South Africa 3 11–12 5–6 24–30 8–18 4–7 28–32 8–17 2–3 V? few x–h  Zambia 2 12+–14+ 5–6 18–21 15–20 6–7 20–21 15–16 3+ III ? x   Range  11–20  5–9  18–34  8–27  4–8  20–32  8–22  2–4  III–V  2?–10  x–h   Cryptic sibling sp.  São Thomé 4 14–24 – 23–26 4–8 – 22–31 6–8 2–3 ? Few– 13 ?  Uganda 5 12–18 6–8 15–21 12–15 4–9 16–19 13–16 3 II–IV 18–21 x–h Where: ant. hd set = number of marginal setae anteriorly between eyespots; post hd set = number of marginal setae between each eyespot and anterior stigmatic area; ant marg ss = number of marginal stigmaticsetae in anterior cleft; ant. non-m. ss = number of non-marginal stigmaticsetae in anterior cleft; lat.m set = number of marginal setae between clefts on each side; post m. ss = number of marginal stigmaticsetae in each posterior cleft; post non-m. ss = number of non-marginal stigmaticsetae in each posterior cleft; depth = number of rows of stigmatic setae in each cleft; ant mldp = most anterior segment on which multilocular disc-pores found; hd tub. ducts = number of ventral tubular ducts in cephalic region; and dent = presence of a claw denticle (where x = absent; h = hint).
