Aceria korykis n. sp. ( Fig. 4 View FIGURE 4 )
DIAGNOSIS – With 5rayed empodium; prodorsal shield bearing a small, distinctly rounded anterior lobe and typical shield design.
REMARKS – Aceria korykis n. sp. resembles A. acalyphae Mohanasundaram, 1990 , described from Acalypha fruticosa Forsk. from India, causing whitish erineal patches on both sides of the leaf, differing mainly in relation to the empodium (4rayed in A. acalyphae ), the number of coxisternal annuli (56 in the n. sp., 8 in A. acalyphae ) and prodorsal shield design.
FEMALE – (n = 6). Idiosoma 155 (135180) long, 51 (5155) wide. Gnathosoma: basal seta 3 (23); antapical seta 4 (45); chelicera 12 (1113). Prodorsal shield 28 (2832) long, 32 (2832) wide, with a small but distinct rounded anterior lobe. Shield design consisting of median, admedian, a pair of submedian lines and 2 pairs of lateral diagonal lines. Shield flanked by short dashes. Scapular seta (sc) on rear shield margin, set on tubercle, pointing backwards, 18 (1821) and 22 (2024) apart. Legs: leg I 23 (2324); femur 8 (7 8), femoral seta (bv) 7 (79); genu 4, genual seta (l”) 18 (1819); tibia 4 (45), tibial seta (l’) basal, 4; tarsus 5 solenidion (Z) 6 (67), empodium 4, 5rayed, dorsal seta (ft’) 11 (10 11), lateral seta (ft”) 16 (1619), unguinal seta (u’) 3 (34).

Opisthosoma evenly rounded in cross section, annuli fully microtuberculate. Lateral seta (c2) 19 (18 24), on annulus 4 (45) counting from genitalia rear margin; ventral seta I (d) 36 (2736), 33 (3236) apart, on annulus 16 (1618); ventral seta II (e) 11 (912), 16 (1418) apart, on annulus 30 (2832); ventral seta III (f) 20 (1820), 19 (1819) apart, on annulus 50 (4754) or on annulus 6 from rear.

TYPE MATERIAL – Female holotype, 89 female paratypes, 3 male paratypes, from Acalypha reptans Sn. (Euphorbiaceae), Piracicaba , São Paulo, Brazil (22o42’30” S, 47o 38’08” W), coll. G.J. Moraes, 1 March 2001, on 10 microscopic preparations in the collection of Departamento de Entomologia, Fitopatologia e Zoologia Agrícola, Universidade de São Paulo ESALQ, Piracicaba, São Paulo, Brazil GoogleMaps .
RELATIONSHIP TO HOST – Small erineal galls on leaves and leaf distortion.
ETYMOLOGY – The specific designation korykis is derived from korykis, Greek for gall on leaves, referring to the damage caused by the mite on the host plant.
