Ixodes dendrolagi Wilson, 1967 : Figs 2 -3: 848-849.

Female

Idiosoma body — unengorged idiosoma ovoid, widest between spiracular plates, unengorged length from apices of scapulae to posterior body margin (3.22 mm); width (2.10 mm); engorged idiosoma oblong, widest anterior to spiracular plates; moderate number of short fine setae on ventral and dorsal surfaces, more numerous outside genital groove.

Scutum — distinctly longer than wide, widest slightly anterior to terminal edge of lateral carinae posterolaterally, anterolateral margin with slight concavity, posterior margin rounded; scapulae blunt, broadly rounded; lateral carinae distinct, slightly curved along length of scutum, beginning at inner margin of scapulae, extending two thirds length of scutum to anterolateral edge of posterolateral margin of scutum; corrugations absent on posterior margin of scutum; cervical grooves faint, deepest anteriorly, extremely faint posteriorly, terminating slightly posterior to widest part of scutum; scutum surface smooth, with short indistinct setae, inconspicuous evenly distributed punctations throughout, three uneven chains of large punctations present at anterior edge of scutum between scapulae at level of cervical grooves, several uneven chains of large punctations along posterior edge of scutum.

Sternal plate — elongate triangular, edges rounded, shape variable, surface with small, scattered punctations, small number of fine setae present on surface.

Spiracular plate — subcircular, slightly elevated; chain of aeropyles along edge of plate roughly parallel to sides, other aeropyles distributed randomly towards centre of plate, no

Tarsi and pulvili — Tarsia abruptly narrowed distally, with moderate subapical humps; pulvilli almost as long as claws.
