Legs
(

. 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. 30
)
. Fixed digit 25 long with three teeth; and movable digit 23 long with one tooth.
Spermatheca
(
Fig. 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:
