Typhlodromus moraesi sp. nov.

( Figs. 1–7 )

Type material

Holotype female, from Tabebuia alba (Cham.) Sandwith. (Bignoniaceae) , March 24, 2000, UNESP Campus (20º47’03” S, 49º21’36” W), São José do Rio Preto, São Paulo, Brazil, M. R. Bellini coll.. Paratypes: 3 females and 1 male, March 27, 2001; 1 male, November 28, 2000; 1 male, January 29, 2001, same host, type locality and collector as holotype; 1 female, Chamaesyce hirta (L.) Millsp. ( Euphorbiaceae ), April 14, 2000, Pindorama (21º13’43” S, 48º54’54” W), São Paulo, Brazil, M.A. Nunes coll..

Diagnosis

This species differs from T. arizonicus by having setae Z4 and Z5 serrate; the calyx of the spermatheca more elongate; ventri­anal shield of the female subquadrate and smooth; and by the absence of macrosetae on tarsus IV.

Description

Female ( Figs. 1–5 ) (5 specimens measured).

Dorsum ( Fig. 1 ): Dorsal shield reticulate, 360 (326–381) long, 196 (185–204) wide at level of s4; setae: j1 19 (16–22), j3 19 (16–22), j4 15 (14–16), j5 15 (14–16), j6 20 (16–22), J2 21 (19–22), J5 8, z2 14 (11–16), z3 14, z4 17 (16–19), z5 13 (11–16), Z4 34 (33–35), Z5 40 (38–41), s4 18 (16–19), s6 18 (14–22), S2 22 (22–24), S5 17 (16–19), r3 17 (16–19), R1 17 (14–19). All setae smooth, except Z4 and Z5 which are serrate.

Peritreme: Extending forward to the level of j1.

Ven te r ( Fig. 2 ): Sternal shield smooth, slightly longer than wide; bearing two pairs of setae (st1 and st2) and two pairs of lyrifissures; st3 inserted on a weakly sclerotised plate separated from the sternal shield; distances between st1–st3 62 (54–68) and between st2–st2 62 (60–63). Genital shield smooth, distance between st5–st5 73 (68–79). Ventrianal shield smooth, longer than wide (1.3:1), with lateral margins slightly concave at JV2 level, with four pairs of pre­anal setae and a pair of pores posterior to JV2; 115 (109–122) long, 90 (84–95) wide at level of ZV2, 81 (76–84) wide at level of anus.

Chelicera ( Fig. 3 ): Fixed digit 24 (22–24) long, with two teeth; movable digit 26 (24–27) long, with one tiny tooth.

Spermatheca ( Fig. 4 ): Calyx cylindrical, 21 (19–22) long. Atrium nodular. Legs: Macrosetae absent; chaetotaxy of geII 2,2/0,2/0,1; geIII 1,2/1,2/0,1.

Male: ( Figs. 6 and 7 ) (3 specimens measured).

Dorsum: Dorsal shield reticulate; 319 (299–332) long, 186 (177–196) wide at level of s4, j1 16, j3 19, j4 15 (14–16), j5 15 (14–16), j6 18 (16–19), J2 21 (19–22), J5 10 (8–11), z2 15 (14–16), z3 15 (14–16), z4 17 (14–19), z5 15 (14–16), Z4 37 (35–41), Z5 36 (35–38), s4 19 (16–22), s6 23 (19–24), S2 23 (19–24), S5 17 (16–19), r3 18 (16–19), R1 19. All setae smooth, except Z4 and Z5 which are serrate.

Peritreme: Extending forward to level of j3.

Ve n t e r: sternogenital shield mostly smooth. Ventri­anal shield subtriangular sligthly reticulate; 122 (120–125) long and 169 (155–182) wide at anterior corners, with 4 pairs of preanal setae; one pair of pores posterior and centraly to bases of JV2; 2 pairs of anterolateral lyrifissures ( Fig. 6 ).

Spermadactyl: Shaft 13 (11–14) long ( Fig. 7 ).

Legs: Macrosetae absent; chaetotaxy of genua II and III as in females.
