Allogamasellus Athias-Henriot  (3 described species)

Movable and fixed cheliceral digits with 3–6 and 6–10 teeth, respectively. Epistome with an anteromedian extension wider at base. Seta h 3 about in longitudinal line with h 1 and slightly posterior and mediad to h 2. Idiosoma elongate, 250–320 µm long and 130–210 µm wide at widest level. Podonotal and opisthonotal shields separated. Dorsal idiosomal setae aciculate, pectinate or serrated laterodistally. Podonotal region of dorsum with 24 pairs of setae, of which 20–22 pairs on podonotal shield and 0–4 pairs on soft integument along lateral margins of podonotal shield. Opisthonotal region with 22–23 pairs of setae, of which 17–19 pairs on opisthonotal shield and 3–6 pairs on soft integument along lateral margins of opisthonotal shield. Seta j 1 not on prominent protuberance, longer or shorter than r 3 and Z 5. Opisthonotal and ventrianal shields separated. With 3–5 pairs of presternal platelets. Sternal shield not fused to endopodal shield near coxa IV; st 4 slightly laterad to imaginary line between st 1– st 3. Opisthogaster with 0–1 platelet between genital and ventrianal shields; with 5–7 pairs of setae on ventrianal shield and 0–2 pairs on soft integument around ventrianal shield; post-anal seta longer, as long as or shorter than para-anal seta. Peritreme with straight or smoothly curved margins, extending anteriorly to posterior margin of coxa III. Peritrematal shield fused posteriorly to exopodal shield near coxa IV, with connection behind stigma wider than peritreme. Exopodal shields near coxae II –III –III usually fused. With a pair of elongate metapodal platelets. All legs with pretarsi (pretarsus I absent in A. castilhoi  ). Genua I, III and IV and tibia IV with 13, 8–9, 10 and 10 setae, respectively.
