Quadromalus columbiensis Moraes, Denmark and Guerrero, 1982: 17
The biology of this species found only once in Colombia on Tanicum paniculatum (Moraes et al., 1982) remains totally unknown.
Previous Records — Colombia (Moraes et al., 1982; Moraes et al., 2004b).
Specimens examined — Guadeloupe, Basse- Terre, Petit-Bourg, Domaine Duclos de l’INRA Antilles-Guyane, 16°12’N, 61°39’W, alt. 85 m, 3 ♀ + 1 ♂ on Cissus verticilata, Kreiter coll., 18 December 2008.
Remarks — this is the first record of this species in the West Indies. The measurements and description of the three female specimens collected fit very well those given by Moraes et al. (1982). No measurement for the male was given in Moraes et al. (1982). Diagnosis proposed by Moraes et al. (1982) corresponds very well to the specimens collected in Guadeloupe: Z4 and Z5 not serrated, only one macroseta on leg IV, 3-4 teeth on fixed and 3 on movable digits, respectively, and moreover 4 extralong setaceous setae on the tarsus 1 (Moraes et al., 1982).
The average measurements of three adult females presently found are as follow: dorsal shield smooth, dorsal shield length 370 (361 – 385), width 246 (239 – 2555), 6 solenostomes (gd 1, 2, 4, 6, 8 and 9), j1 29 (28 – 30), j3 38 (37 – 40), j4 13 (12 – 13), j5 14 (13 – 15), j6 12, J2 19 (17 – 20), J5 13, z2 37, z4 41 (40 – 42), z5 17 (15 – 20), Z1 27 (25 – 3), Z4 34 (33 – 35), Z5 33, s4 44 (42 – 45), S2 34 (33 – 35), S4 31 (28 – 32), S5 28 (25 – 30), r3 34 (33 – 35), R1 30, all setae smooth, st1-st1 56 (55 – 58), st2-st2 66 (60 – 75), st1-st3 70 (60 – 75), posterior margin of the sternal shield not straight, metapodal 1 length 25, width 7 (6 – 8), metapodal 2 not visible, ventrianal shield 103 (100 – 108) long, 57 (48 – 67) wide at level of anterior corners and 68 (60 – 75) wide at level of anus, 4 poroids around the ventrianal shield, JV5 41 (40 – 43), spermatheca 24 (20 – 28) long and 3 width, SgeI 25 (23 – 28), SgeII 22 (20 – 23), SgeIII 24 (23 – 25), StiIII 21 (20 – 23), SgeIV 29 (28 – 30), StiIV 26 (24 – 28), StIV 41 (40 – 42), macrosetae very slightly knobbed, fixed digit of chelicerae 31 (28 – 32), mobile digit of chelicerae 32 (30 – 35), 3 large strong denticles on fixed digit and 3 large strong denticles on mobile digit.
