Dorsal shield variously sclerotised and ornamented, with 28 - 29 pairs of setae, including z 6; setae Z 2 absent in some species. Dorsal shield setae similar in adults of both sexes, relatively short (with tips never reaching bases of the following setae of the same longitudinal rows), mostly smooth and spatulate, sometimes crenelated, paddle-shaped or spoon-shaped, with a broad flat end tapering to the base; setae j 1 otherwise modified, smooth or serrate, usually with pointed apex, and often with ventral position on vertex. In female, st 1 and st 2 on sternal shield, st 3 on small suboval or subtriangular pseudo-metasternal platelets, and st 4 on soft integument; endopodal platelets II-III well developed, relatively large, subtriangular and close to posterolateral angles of sternal shield; anterior margin of epigynal shield usually deeply concave to form two cusps, genital poroids on soft integument. Opisthogastric region with five pairs of setae in females and males (JV 1 - JV 3, JV 5, ZV 2; JV 4 absent); setae JV 5 usually similar to those on dorsal shield, other ventrally inserted setae simple, smooth and needle-like; females with three pairs of opisthogastric setae (JV 1, JV 5, ZV 2) on soft integument and two pairs (JV 2, JV 3) on ventrianal shield; male with more expanded ventrianal shield bearing all five pairs of opisthogastric setae. Peritrematal shields anteriorly fused to dorsal shield, with enlarged cavity-like poroid structure at the level of coxa III and well developed parapodal portion. Metapodal platelets relatively large, longitudinally elongate. Soft striate integument simple, not with additional sclerotic granulation. Corniculi normally sclerotised, well spaced and trifid; setae h 1 markedly thickened proximally, curved and abruptly tapered medially, attenuate distally, and sharply pointed apically. Fixed digit of chelicera with three subequal teeth on proximal masticatory area; male spermatodactyl small, shorter than movable cheliceral digit. Epistome with anterior margin produced into narrow and bifid central projection; lateral margins with several minute spines. Palptarsal apotele two-tined. Coxae I-IV with rows of minute spines, coxae II with spine-like process on anterior surface; coxae I-IV and femora I-IV with lamellar and / or papular sclerotic structures. Genu III, and tibiae III-IV with two anterolateral and two posterolateral setae. Tarsi I-IV each with empodium and rudimentary claws, or claws absent. Insemination apparatus with papilla-like sperm induction pores (solenostomes) associated with inner margin of coxae III; spermathecal ducts free and elongated.","source":"A revision of the family Ameroseiidae (Acari, Mesostigmata), with some data on Slovak fauna","sourceTaxonKey":135026445}]}
