Ologamasus Berlese View in CoL (20 described species)
Movable and fixed cheliceral digits with 3–4 and 4–10 teeth, respectively. Epistome with an anteromedian extension wider at base, acute or bifurcate distally, smooth or with one to several spines, flanked or not by one pair of large anterolateral extensions, as long as or shorter than anteromedian extension (with an anteromedian extension of about uniform width along its entire length in O. foliatus ; convex and serrated in O. testudinis ). Seta h 3 about in longitudinal line with h 1 and slightly anterior and mediad to h 2. Idiosoma suboval, 460–950 µm long and 260–840 µm wide at widest level. Podonotal and opisthonotal shields fused, forming holonotal shield. Dorsal idiosomal setae aciculate and smooth, or spatulate and pilose. Podonotal region of dorsum with 16–23 pairs of setae, of which 16–23 pairs on podonotal shield and without setae on soft integument along lateral margins of podonotal shield. Opisthonotal region with 12–20 pairs of setae, of which 12–20 pairs on opisthonotal shield and without setae on soft integument along lateral margins of opisthonotal shield. Seta j 1 not on prominent protuberance, as long as or shorter than r 3 and Z 5. Holonotal and ventrianal shields fused. With a pair of presternal platelets. Sternal shield not fused to endopodal shield near coxa IV; st 4 lateral to st 1– st 3. Opisthogaster without platelets between genital and ventrianal shields (with four platelets in O. striolatus ); with 6–9 pairs of setae on ventrianal shield and without setae on soft integument around ventrianal shield; post-anal seta longer than, as long as or shorter than para-anal seta. Peritreme with straight or smoothly curved margins, extending anteriorly to level between middle region of coxa II and coxa I. Peritrematal shield fused posteriorly to exopodal shield near coxa IV, with connection behind stigma wider than peritreme (shorter in O. striolatosimilis and O. striolatus ). Exopodal shields near coxae II–III–III divided at median level of coxa III. Without distinct metapodal platelets. All legs with pretarsi. Genua I, III and IV and tibia IV with 13, 9, 10 and 10 setae, respectively.
