Guerrero• ---ABSTRACT-This is the second report of the phytoseiids of Colombia. A new genus and species, Quadromalus colombiensis and Euseius ricinus n. sp. are described, bringing the total to 17 species of phytoseiids for Colombia.------RESUMO-ACAROS FITOSEIDEOS DA COLOMBIA (ACARINA: PHYTOSEIIDAE). Este e o segundo relate sobre os acaros fitoseideos da Columbia. Um novo genero e duas novas especies sao descritas, Quadromalus colombiensis e Euseius ricinus sp. n., elevando para 17 o numero total de especies conhecidas.---15 In 1972, Denmark and Muma reported 11 species of phytoseiids from Colombia. These species were: Amblyseius anacardii De Leon, Amblyseius deleoni Muma and Denmark [a synonym of A. herbicolus (Chant)], Euseius flechtmanni Denmark and Muma [a synonym of Euseius concordis (Chant)], Euseius paraguayensis Denmark and Muma [a synonym of Euseius alatus De Leon], Euseius naindaimei (Chant and Baker), Iphiseiodes zuluagai Denmark and Muma, Typhlodromips sinensis Denmark and Muma, Typhlodromalus peregrinus (Muma), Neoseiulus anonymus Chant and Baker, Diadromus regularis (De Leon), and Phytoseius purseglovei De Leon. The Centro Interamericano de Agricultura Tropical has been researching the ecology of mites associated with cassava, Manihot esculenta Crantz, (Guerrero, 1980; Guerrero and Bellotti, 1980), in order to evaluate the role they play and the possibility of utilizing the native predators in cassava pest management. The phytoseiids are important predators of phytophagous mites. This paper reports on the phytoseiids found in Colombia by Dr. J. M. Guerrero in relation to ecological studies. Ali measurements are in micra. Quadromalus Moraes, Denmark and Guerrero, new genus TYPE SPECIES-Quadromalus colombiensis Moraes, Denmark and Guerrero. FEMALE-Moderate size species.

Vol. 8, No. 1 Internat. J. Acarol 17 Venter: Chaetotaxy St 2, PAS 3, VL 4. Sternal scutum longer than wide, slightly creased with 2 pairs of pores, 2 pairs of moderate setaceous setae, and indistinct to trilobed posteriorly. Genital scutum smooth with slight crease on each side posteriorly, 1 pair of moderate setaceous, and about twice as wide as the ventrianal scutum. Ventrianal scutum vase-shaped, about one-third the width o f the body, lightly creased with 2 to 3 pairs o f preanal setae, and a pair of pores. Ventrolateral setae tiny to moderate setaceous and arranged in 2 rows beside the ventrianal scutum. Metasternal scuta present, irregular in shape with a moderate setaceous seta on each one. Metapodal scuta narrow and elongate. Peritreme normal in width (1 primary pore present) and extending beyond L 1; peritremal and stigmatal seu ta fused, peritremal scutum extending as an ectal strip around leg IV. Spermathecae: Tubular-fundibular; atrium indistinct nodular. Cervix 26 long. Chelicerae: Moderate in size in relation to body size with 3 large denticules on the mf, and 3 large and 1 small denticule on the ff. Legs: Macrosetae chaetotaxy = 0,0,0,1. Genu 11 2- ~- 1; Genu 111 1 -! -1.- 1. Leg formula: 4123. o I O MALES-Similar to but slightly smaller than the female. Ventrianal scuta shield-shaped with a pair of preanal pores and 3 pairs of tiny, setaceous, preanal setae. Spermatodactyl with foot terminal, enlarged toe as in Typhlodromalus without lateral process. DISCUSSION-This genus is closely related to Typhlodromalus Muma. It differs by having at least 4 extra long setaceous setae on tarsus I, the chelicerae are larger with 3 large denticules on the mf and 3 large and 1 small denticules on the ff.
