ST3 and the metasternal setae (ST4) on separate platelets, with a pair of small poroids with ST4. Genital shield 110 (90 – 129) long, 54 (48 – 60) wide (at level of ST5), smooth. Three elongate platelets or genital sigilla situated between genital and ventrianal shields. One pair of poroids close to the genital shield (ST 5) and 4 pairs of poroids around the genital shield. Ventrianal shield subtriangular-shaped, 102 (85 – 118) long and 77 (60 – 84) wide (at level of ZV2), smooth or faintly striate, with four pairs of preanal setae (JV1, JV2, JV3 and ZV2) and a pair of small solenostomes gv3 posteromediad to JV3. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 34 (30 – 38) long, smooth.

Three pointed macrosetae 33 (31 – 34), 31 (30 – 32) and 55 (51 – 59) long on genu, tibia and basitarsus IV, respectively.

Material examined — Three female paratypes deposited in the Department of Agroforestal Ecosystems , Universidad PolitØcnica de Valencia, Spain .

Adult male ( Figure 18f, g )

Dorsal shield slightly reticulated and chaetotaxy similar to the female. Sub-lateral seta R1 on the dorsal shield. Ventrianal shield 118 long and 150 wide, slightly reticulated and bearing 7 pairs of preanal setae and 4 pairs of poroids. Spermatodactyl L-shaped. This description is based on a male paratype specimen .
