description: <i>Abacarus nectandrae</i> n. sp. (Fig. 1) DIAGNOSIS – With 7 ­rayed empodium, no seta on tibia I and femur I and epigynium with arched transversal lines. REMARKS <b>–</b> This new species is unique among the members of the genus <i>Abacarus</i> by missing setae concurrently on tibia and femur of leg I. FEMALE – (n = 6). Idiosoma 174 (145­187) long, 61 (54­61) wide. <b>Gnathosoma</b> 25, antapical seta not discernible; basal seta 4 (3­4). <b>Prodorsal shield</b> 37 (36­41) long, with distinct frontal lobe; anterior half with short longitudinal dashes, separated from posterior half by a sinuous transverse line; posterior half with admedian lines, and a transverse line curved backwards between shield tubercles. Dorsal shield tubercles distinctly elongate, directing scapular seta (<i>sc</i>) backwards. Scapular seta 35 (32­35) apart, needle­like, 9 (8­9) long. <b>Legs</b>: leg I 25 (23­26); femur elongate, 9 (7­9), femoral seta (<i>bv</i>) missing; genu 4 (3­ 4), genual seta (<i>l”</i>) 26 (25­27); tibia 4 (3­4), tibial seta (<i>l’</i>) missing; tarsus 5 (5­6), solenidion (Z) knobbed, 4 (5­7), empodium 7 ­rayed, 5 long, dorsal seta (<i>ft’</i>) 13 (11­14), lateral seta (<i>ft”</i>) 18 (16­18), unguinal seta (<i>u’</i>) 5 (4­5). Leg II 21 (21­23); femur 9 (8­9), <i>bv</i> 19 (18­20); genu 3, <i>l”</i> 12 (11­12); tibia 3; tarsus 4 (4­5), solenidion (Z) long, 15 (15­18), empodium 5 (4­6), 7 ­rayed, <i>ft’</i> 4, <i>ft”</i> 22 (22­26), <i>u’</i> 4 (3­4). <b>Coxisternal area:</b> coxae I fused, granulated, no sternal line; coxal seta I (<i>1 b</i>) 4 (4­5), 7 (5­8) apart; coxal seta II (<i>1 a</i>) 20 (14­20), 11 (11­12) apart; coxal seta III (<i>2 a</i>) 31 (30­33), 23 apart. Coxigenital area with 2 (2­3) transverse lines of microtubercles and no other evidence of annuli. Genitalia 18 (18­19) wide, 18 (14­18) long; epigynium with 2 pairs of curved transverse lines; genital seta (<i>3 a</i>) 25 (22­33). <b>Opisthosoma</b>: dorsomedian ridge extends to approximately midway the distance between ventral setae II and III; lateral ridges fade away shortly behind. Lateral seta (<i>c 2</i>) 42 (40­44), on annulus 3 (3­4), counting from rear margin of genitalia; ventral seta I (<i>d</i>) 53 (49­58), 34 (33­35) apart, on annulus 14; ventral seta II (<i>e</i>) 42 (38­47), 19 (18­21) apart, on annulus 29 (26­28); ventral seta III (<i>f</i>) 13 (12­15), 12 (12­13) apart, on annulus 45 (42­45) or 6 th from rear. Total ventral anuli 50 (47­50), with elongate microtubercles; total dorsal annuli 43 (42­45), smooth except for the caudal 9 (7­8) annuli which bear minute bead­like microtubercles on posterior margins. Caudal seta (<i>h 2</i>) 46 (40­49), accessory seta (<i>h 1</i>) 1 (1­2). MALE – not seen. TYPE MATERIAL – Female holotype, 23 female paratypes, from <i>Nectandra membranacea</i> (Sw.) Griseb, (Lauraceae), Pariquera­açu, São Paulo, Brazil (24 o 36 ’ 51 ”S, 47 o 53 ’ 22 ” W), coll. G.J. Moraes, 19 May 2001, on 6 microscopic preparations deposited in the collection of Departamento de Entomologia, Fitopatologia e Zoologia Agricola, Universidade de São Paulo, ESALQ, Piracicaba, SP, Brazil. RELATIONSHIP TO HOST – vagrants on the underside of leaves; no apparent damage. ETYMOLOGY – The specific designation <i>nectandrae</i> is derived from <i>Nectandra</i>, the name of the genus of the plant on which the new species was collected.
