(Type species: <i>A. cornutus</i> Hunt &amp; Lee, 1995 by original designation.) Type species. <i>Pedrocortesella pulehra</i> Hammer, 1961, by monotypy. Diagnosis. Prodorsum with deep transverse furrow, enantiophyses lacking, bothridium abutting notogaster, sensillus nearly always a petiolate blade, rarely a petiolate club; seta <i>ex</i> absent; notogaster flattish in lateral aspect, usually concave inside the margin; integument alveolate-reticulate, foveate-reticulate or punctate; 5-6 pairs of notogastral setae, 2-3 of which are anterior to fissura <i>ip,</i> setae <i>p2x</i> never lateral or posterior to <i>ip;</i> setae <i>p2x</i> and <i>p3x</i> at same level as <i>hI,</i> not on posterior flank at same level as <i>pI; lm</i> if present not mesad of fissura <i>im</i> but well posterior to it; seta <i>ag</i> anterior to posterior margin of genital valves; 2 (rarely 3) pairs of anal setae, 2-3 pairs adanal; tarsal cluster orientated dorsad or distodorsad, solenidion <i>omega I</i> usually shorter than seta <i>fi";</i> integument of legs usually reticulate or in wavy crests; iteral setae absent on tarsus of leg IV Description Plateremaeoid mites ofmedium size (400-750 <i>/lm);</i> body covered with layer of cerotegument, reticulation pattern and other high points usually with stellate cushion-like mounds of cerotegument which often coalesce into crests; notogaster of adults ovate, adult carrying exuvial scalps or scalps may be absent or missing; prodorsum with deep transverse furrow but no enantiophyses; seta <i>le</i> lateral or dorsolateral, <i>ro</i> ventrolateral; seta <i>ex</i> absent; seta <i>in</i> small, spinous and arising from apophysis; bothridium with posterolateral carina; bothridium abutting notogaster, its posterior wall sometimes incomplete; distal part of sensillus usually a flattened, tuberculate blade; notogaster flattish in lateral aspect, concave intramarginally, concave area often U-shaped or obovate; integument alveolate-reticulate, foveate-reticulate, or punctate; 5-6 pairs of marginal setae in posterior part of notogaster, setae <i>hI, lpx, p2x</i> and <i>p3x</i> situated dorsally, latter two always anterior to fissura <i>ip; pI</i> situated on posterior flank ventral to <i>hI, lm</i> usually absent, if present situated well posterior to fissura <i>im;</i> pedipalp tarsus seta <i>I"</i> usually with barbs, apophysis supporting eupathidial seta <i>aem</i> short; ventral antiaxial and paraxial processes on chelicera well developed; anal and genital plates close; genitoanal chaetotaxy 6-7:1:2(rarely 3):3(rarely 2); genital setae either forming straight line near inner margin of plate, or forming an arc; seta <i>ag</i> anterior to posterior margin of genital valves; setae <i>adI</i> usually posterior to anal plates, setae <i>ad3</i> usually most laterad; cerotegument on legs reticulate, often forming strong wavy crests; leg tarsi heterotridactylous, laterals weaker than central prong; stalk usually short and stout, tarsus sometimes with distal recess to receive retracted unguinal complex; tarsal cluster ofleg I with setafi" and solenidia <i>omega I</i> and 2 usually surrounded by collar, though former may be partitioned from solenidia; entrance to cavity containing undeveloped famulus (seta <i>epsilon)</i> not usually visible under SEM; <i>omega I</i> and 2 usually shorter than <i>ft";</i> iteral setae absent on tarsus of leg IV Comments. The belief by Aoki (1974, 1984) and Ryabinin (1986) that <i>Pedrocortesella</i> is a junior synonym of <i>Pedroeortesia</i> is not accepted in this work. <i>Pedroeortesia</i> is now regarded by most authors as a junior synonym <i>ofPheroliodes,</i> whereas <i>Pedrocortesella</i> is regarded as a separate taxon (Hunt &amp; Lee, 1995). Hunt &amp; Lee (1995) erected the monotypic genus <i>Aeupedieellus</i> for <i>A. cornutus.</i> Increased knowledge of the Australian fauna and re-examination of the type species of <i>Pedrocortesella</i> suggest that the variation in leg I structure on which the genus was based does not warrant separate generic status. The dorsal apophysis on the femur of leg I and the tapering tarsus are best regarded as autapomorphies for the species. The species becomes <i>Pedrocortesella cornuta,</i> n.comb. The nominal species <i>P dispersa</i> and <i>P queenslandica</i> each represent radiations which warrant separate generic status and are redescribed elsewhere (Hunt, 1996b; 1996c). Key to adults of Australian species of <i>Pedrocortesella</i> (For identification under transmitted light the animal should be cleared. Scalps, if present, should be noted and removed to assist identification). 1 Terminalpartof sensillus aflattenedblade(Figs 39 Dand39A TODO TODO TODO TODO TODO show differentaspects), curvedandnot truncatedistally..................................................
