Pachymasiphis new genus (2 described species)

Movable and fixed cheliceral digits with three and five teeth, respectively. Epistome with an anteromedian extension wider at base, acute distally, smooth or serrated. Seta h 3 about in longitudinal line with h 1 and slightly posterior and mediad to h 2. Idiosoma elongated, 360–440 µm long and 170–240 µm wide at widest level. Podonotal and opisthonotal shields fused, forming holonotal shield. Dorsal idiosomal setae aciculate and slightly pilose. Podonotal region of dorsum with 21–22 pairs of setae, of which 21–22 pairs on podonotal shield and without setae on soft integument along lateral margins of podonotal shield. Opisthonotal region with 19–20 pairs of setae, of which 19–20 pairs on opisthonotal shield and without setae on soft integument along lateral margins of opisthonotal shield. Seta j 1 not on prominent protuberance, shorter than r 3 and Z 5. Holonotal and ventrianal shields separated. With a pair of presternal platelets. Sternal shield fused to endopodal shield near coxa IV; seta st 3 mediad to imaginary line between st 1, st 2 and st 4. Opisthogaster without platelets between genital and ventrianal shields; with six pairs of setae on ventrianal shield and a pair on soft integument around ventrianal shield; post-anal seta longer than para-anal seta. Peritreme with straight or smoothly curved margins, extending anteriorly to level of posterior margin of coxa I. Peritrematal shield fused posteriorly to exopodal shield near coxa IV, with connection behind stigma wider than peritreme. Exopodal shields near coxae II–III–III fused. Without distinct metapodal platelets. Pretarsi I–IV uniform in size, leg chaetotaxy unknown. Leg II greatly enlarged, tarsus and tibia II with cuticular apophyses and with some very heavy, thickened and spur-like setae.
