Winlundia Newell, 1984

Type species — Winlundia filistoma Newell, 1984

Idiosoma — Dorsum with three pairs of gland pores, one on AD, OC and PD, and (five? to) six pairs of dorsal setae. Gland pores not on cones. AE with epimeral pores and three pairs of ventral setae, pair of PE each with one dorsal and three ventral setae. Female GA with three pairs of pgs and each genital sclerite with two sgs. Male genital sclerites with three to five pairs of sgs; GO with two pairs of internal acetabula ( Figure 1E ).

Gnathosoma — Slender, with long, narrow rostrum. Basal pair of maxillary setae on gnathosomal base. Palps four-segmented, laterally attached. P-2 with one dorsal seta, P-4 with three setae in basal whorl; no seta on P-3.

Legs — Genua shorter than telofemora and tibiae. Basifemora I to IV with 2, 2, 2, 2 setae, telofemora with 4-5, 3-5, 2, 2-3 (in W. filistoma 4, 3, 2, 2, in W. furcata 5, 5, 2, 3) and genua with 3, 3, 3, 3 setae. Tibiae I to IV with 7, 6, 5, 5 setae, of these 4, 3, 2, 2 in ventral position. Tarsi I and II with dorsolateral and dorsomedial solenidion, respectively. Tarsus I with two ventral setae, a basal slender one ventromedial in position and an apical eupathid one ventrolateral in position; tarsi II to IV lack ventral setae.

Deutonymph — Genital plate of W. filistoma with two pairs of pgs and two pairs of internal acetabula.
