Hypoaspis calcarata sp. nov. ( Figs 10–15 View FIGURES 10 – 15. 10 )
Specimens examined
Holotype female, Hermanus, 28.viii.1994, T. K. Qin coll., clover and weeds, Site 30– 31 (= 9431). Paratype female, Plettenberg Bay, 18.viii.1994, roadside picnic area, T. K. Qin coll., clover and capeweed, site 30–13 (= 9413).
Description (Female)
Dorsal idiosoma ( Fig. 10 View FIGURES 10 – 15. 10 ). Length 512–517 µm, width at widest point 294–307 µm (n=2). Dorsal shield with 34 pairs of setae and two unpaired posteromedian setae (Jx, or possibly J2); setae subequal in length (50–60 µm) except z1 shorter (20 µm) and Z5 longer (75 µm).
Ventral idiosoma ( Fig. 11 View FIGURES 10 – 15. 10 ). Tritosternum with rectangular base and two lightly pilose laciniae; presternal area with weak irregular transverse lines; sternal shield with three pairs of long robust setae and two pairs of lyriform pores, with indistinct lineate ornamentation anteriorly, posteriorly smooth. Genital shield elongate, dropshaped, with one pair of genital setae and weak lineate ornamentation; metasternal plates minute, each bearing a pore; metasternal setae inserted in soft integument; anal shield triangular, with a pair of paraanal setae and a postanal seta; cribrum small, confined to area behind postanal seta; opisthosomal integument with a pair of elongate metapodal plates, two pairs of minute platelets, and ca. 12 pairs of opisthogastric setae. Peritrematal shields narrow, extending from level with seta s1 to a short triangular extension posterior to the stigmata.
Gnathosoma . Hypostomal groove with 6 rows of denticles, 2–3 teeth per row; anterior hypostomal seta (h1), interior posterior hypostomal seta (h3) and palp coxal seta subequal in length (ca. 25 µm), exterior posterior hypostomal seta (h2) about half this length; corniculae long and slender, reaching to anterior margin of palp femur ( Fig. 12 View FIGURES 10 – 15. 10 ). Cheliceral digits short and robust, movable digit edentate, fixed digit with a bidentate medial tooth; pilus dentilis very long, fine, dorsal seta thick, spinelike ( Fig. 13 View FIGURES 10 – 15. 10 ). Epistome triangular, very slightly serrated ( Fig. 14 View FIGURES 10 – 15. 10 ). Palp tarsal claw with two subequal tines and a much smaller third tine.
Legs. Chaetotaxy: Leg I. coxa 0 0/1 0/1 0; trochanter 1 0/2 1/1 1; femur 2 2/1 3/3 2; genu 2 3/2 3/1 2; tibia 2 3/2 3/1 2. Leg II. coxa 0 0/1 0/1 0; trochanter 1 0/2 0/1 1; femur 2 3/1 2/2 1; genu 2 3/1 2/1 2; tibia 2 2/1 2/1 2; tarsus 3 3/2 3/2 3 + mv, md. Leg III. coxa 0 0/ 1 0/1 0; trochanter 1 0/2 0/1 1; femur 1 2/1 1/0 1; genu 2 2/1 2/1 1; tibia 2 1/1 2/1 1; tarsus 3 3/2 3/2 3 + mv, md; Leg IV. coxa 0 0/1 0/0 0; trochanter 1 0/2 0/1 1; femur 1 2/1 1/0 1; genu 2 2/1 3/1 1; tibia 2 1/1 3/1 2; tarsus 3 3/2 3/2 3 + mv, md. Anterolateral setae on femur, genu and tibia of leg I very thick, short, spinelike ( Fig. 15 View FIGURES 10 – 15. 10 ); anteroventral setae on these segments also slightly thickened; all other setae fine, smooth, pointed. All legs with two welldeveloped claws and a rounded membranous pulvillus.
Notes
In the classification of Karg (1979) H. calcarata belongs to the oophila species group of Hypoaspis (Holostaspis) . It differs from the other members of this group by the presence of heavy spinelike setae on leg II of the female. It appears to be rare, and is unlikely to play a major role in regulating populations of H. destructor .
