Legs ( Fig. 29View FIGURES 27 – 31). Legs IV with a macroseta on the basitarsus, ST IV 45 (38–53). Chaetotactic formula of genu II: seven setae, 2 2 / 0, 2 /0 1; genu III: seven setae, 1 2 / 1, 2 /0 1.

Chelicera ( Fig. 30View FIGURES 27 – 31). Fixed digit 25 long with three teeth; and movable digit 23 long with one tooth.

Spermatheca ( Fig. 31View FIGURES 27 – 31). Cup-shaped and saccular ( Denmark et al., 1999), with a cervix 17 (15–20) long and 7 wide, with an atrium attached directly to the calyx (absence of neck).

Etymology. The name “ leclanti  ” is in honor of Mr. François Leclant, Professor in Montpellier SupAgro (previously Ecole Nationale Supérieure Agronomique de Montpellier), colleague of two of the authors and great taxonomist of aphids, who has descried many species, especially from Morocco.

Remarks. Within the sub-genus Typhlodromus  ( Typhlodromus  ), three species bear three dorsal shield solenostomes, seven setae on the genu II, four setae and no pores on the ventri-anal shield: T. (T.) baccettii  , T. (T.) kykladiticus  and T. (T.) phylaktioticus  . Table 4 provides the measurements and their range calculated using the intraspecific variations around the means (Tixier, 2012). Typhlodromus (T.) lecanti  differs from T. (T.) baccettii  in the lengths of the setae Z 4, Z 5, S 2 and S 4. T. (T.) lecanti  differs from T. (T.) phylaktioticus  in the spermatheca shape as well as in the cheliceral dentition. Typhlodromus (T.) leclanti  differs from T. (T.) kykladiticus  in the ST IV length and peritreme length.

TABLE 4. Comparison between the Typhlodromus (Typhlodromus) species bearing three solenostomes on the dorsal shield, Typhlodromus (Typhlodromus) ballotae n. sp. and Typhlodromus (Typhlodromus) leclanti n. sp., measurements are taken from the re-descriptions provided by Chant & Yoshida-Shaul (1987). Variations ranges were calculated using the abacus proposed in Tixier (2012).
