Cocoseius paucisetis n. sp.
( Figures 46–50 View FIGURES 46 – 50 )
Diagnosis. Females with dorsal shield reticulate; St3 inserted on separate platelets; four pairs opisthogastric setae (JV1, JV5, ZV1 and ZV2); ventrianal shield ovoid with two pairs of pre-anal setae (JV1 and ZV2); leg macrosetae pointed.
Specimens examined. Holotype female and two paratype females from Syagrus romanzoffiana (Cham.) Glassman, Cananéia , State of São Paulo, 22 July 2001, G.J. de Moraes coll.; deposited at ESALQ-USP.
Description. Female (n= 3). Figures 46–50 View FIGURES 46 – 50 .
Dorsum. Dorsal shield reticulate, with seven distinguishable pairs of lyrifissures and two pairs of pores, 276 (267–285) long and 140 (135–145) wide. Setae j1 20 (19–22), j3 46 (44–48), j4 29 (28–30), j5 31 (30–33), j6 45 (43–47), J2 46 (45–48), J5 31 (30–33), z2 30 (28–33), z3 39 (36–41), z4 51 (50–53), z5 34 (34–36), z6 65 (62–68), Z4 57 (54–59), Z5 61 (58–63), s4 59 (56–61), S4 63 (61–65), r3 45 (43–50), R1 61 (59–64), setae smooth and pointed, except for J5 and Z5, lightly serrate and pointed.
Venter. Sternal shield lightly sclerotised, posterior margin indistinguishable, reticulate, with two pairs of setae and two pairs of lyrifissures; St3 inserted in separated patelets; distances between St1 - St3 54 (52–56), St2 - St2 53 (53–54). Genital shield striate; distance between St5 - St5 57 (56–60). Ventrianal shield ovoid, striate, with two pairs of pre-anal setae (JV1 and ZV2); ZV1 on unsclerotised cuticle and a pair of pre-anal pores posterolaterad of ZV2; 81 (80–83) long, 62 (60–66) wide at anus level. Ventral setae smooth and pointed, except for JV5, lightly serrate. With two pairs of metapodal plates. Peritreme extending almost to the level of r3.
Chelicera. Movable digit 21 long, with one tooth; fixed digit 23 (23–24) long, with three teeth, all distal to pilus dentilis.
Spermatheca. Calyx saccular, slightly swollen near atrium, 8 (8–9) long; atrium small, nodular.
Leg macrosetae. Sge IV 23 (21–26), Sti IV 20 (18–23), St IV 66 (64–69), pointed. Chaetotaxy: genu II 1–2 /0, 2/1–2; genu III 1–2 /1, 2/0–1.
Male. Unknown.
Etymology. The name paucisetis is a compound of pauci (Latin for few) and setis (Latin for setae), referring to the few opisthogastric setae (JV2, JV3, JV4 and ZV3 absent).
Remarks. The species here described is most similar to Cocoseius elsalvador Denmark & Andrews, 1981 but the latter has shorter z2 (18) and longer j5, j6, J2 and s4 (52, 63, 60 and 76 respectively). In addition, it has a shorter peritreme (extending to the level of s4), six pairs opisthogastric setae (JV1, JV2, JV5, ZV1, ZV2 and ZV3) and longer calyx of spermatheca (17–23).
