- Abacarus nectandrae Flechtmann, Carlos H. W., 2002, Zootaxa 23: 2-2.
Diagnosis
DIAGNOSIS – With 7 rayed empodium, no seta on tibia I and femur I and epigynium with arched transversal lines.
Discussion
REMARKS – This new species is unique among the members of the genus Abacarus by missing setae concurrently on tibia and femur of leg I.
Description
FEMALE – (n = 6). Idiosoma 174 (145187) long, 61 (5461) wide. Gnathosoma25, antapical seta not discernible; basal seta 4 (34). Prodorsal shield37 (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 (sc) backwards. Scapular seta 35 (3235) apart, needlelike, 9 (89) long. Legs: leg I 25 (2326); femur elongate, 9 (79), femoral seta (bv) missing; genu 4 (3 4), genual seta (l”) 26 (2527); tibia 4 (34), tibial seta (l’) missing; tarsus 5 (56), solenidion (Z) knobbed, 4 (57), empodium 7 rayed, 5 long, dorsal seta (ft’) 13 (1114), lateral seta (ft”) 18 (1618), unguinal seta (u’) 5 (45). Leg II 21 (2123); femur 9 (89), bv19 (1820); genu 3, l”12 (1112); tibia 3; tarsus 4 (45), solenidion (Z) long, 15 (1518), empodium 5 (46), 7 rayed, ft’4, ft”22 (2226), u’4 (34). Coxisternal area: coxae I fused, granulated, no sternal line; coxal seta I (1 b) 4 (45), 7 (58) apart; coxal seta II (1 a) 20 (1420), 11 (1112) apart; coxal seta III (2 a) 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 (3 a) 25 (2233). Opisthosoma: dorsomedian ridge extends to approximately midway the distance between ventral setae II and III; lateral ridges fade away shortly behind. Lateral seta (c 2) 42 (4044), on annulus 3 (34), counting from rear margin of genitalia; ventral seta I (d) 53 (4958), 34 (3335) apart, on annulus 14; ventral seta II (e) 42 (3847), 19 (1821) apart, on annulus 29 (2628); ventral seta III (f) 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 (h 2) 46 (4049), accessory seta (h 1) 1 (12). MALE – not seen.
Materials Examined
TYPE MATERIAL – Female holotype, 23 female paratypes, from Nectandra membranacea (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
ETYMOLOGY – The specific designation nectandrae is derived from Nectandra, the name of the genus of the plant on which the new species was collected.
