Ornithodoros faccinii n. sp. Barros-Battesti, Landulfo & Luz Diagnosis
Larva with elongated dorsal plate, almost rectangular; the anterior and posterior margins rounded with sides parallel. Idiosoma dorsal with 10 pairs of dorsolateral setae and 3 pairs of central dorsal setae. Idiosoma ventral with 7 pairs of setae (3 sternal, 3 circumanal and 1 ventrolateral pairs) plus 1 anal pair. Hypostome long, pointed, dental formula 3/ 3 in the anterior third, then 2/2 posteriorly to the base. Presence of small spurs at the base of hypostome in the lateral position. Trochanter of palpi with spurs in the internal side and ventrally, some of them are bifid. Nymphs of first
instar with reduced camerostome. Hood and cheeks absent. First pair of posthypostomal setae (Ph1) arising at level of insertion of article II of palpi and half of hypostome. Second pair of posthypostomal setae (Ph2) very short, not reaching the hypostomal basis and corresponding to 1/4 of length of Ph1. Hypostome notched in the apex, dental formula 4/4 apically (3 rows) then 3/3 (3 rows) and 2/2 (3 rows) until posterior margin of article II. Body with mammillae covering both ventral and dorsal surfaces. Genital primordium present. Capsule of Haller ’ s organ U-shaped.
