Ameroseiella

Diagnosis (adults). Dorsal shield well sclerotised and coarsely ornamented, with 29 pairs of setae, including z 6, similar in length and form, thickened, often flattened, with longitudinal vein and smooth or sparsely serrate lateral margins; setae j 1 differently formed, leaf-like to fan-shaped, with distinctive longitudinal midrib and regularly denticulate anterolateral margin. In female, sternal setae on sternal shield (st 1, st 2), soft integument (st 3, st 4) and epigynal shield (st 5); opisthogastric region with six pairs of setae (JV 1 - JV 5, ZV 2), all on soft integument (anal shield with only three circum-anal setae). In male, ventrianal shield with 3 - 4 pairs of opisthogastric setae (JV 1 on or off the shield, JV 5 always off the shield); setae JV 4 absent. Opisthogastric setae mostly smooth, short and needle-like; setae JV 4 pilose; setae JV 5 modified and similar to those on dorsal shield. Corniculi normally sclerotised, relatively slender, with splitted apex; setae h 1 markedly thickened. Cheliceral digits relatively large, fixed digit of chelicera with three well developed teeth on proximal masticatory area (two proximal teeth somewhat adjacent). Epistome with anterior margin produced into long and narrow central projection. Palptarsal apotele two-tined. Genu III, and tibiae III-IV with two anterolateral and two posterolateral setae. Tarsi of legs I with empodium and claws not developed, terminating with four conspicuously lengthened sensory setae and some shorter ones; tarsi II-IV each with normal empodium and claws.
