Comments — B. costaricaensis differs from all other known species by having a small number of broad fimbriate setae on the dorsum. FOLDICOCCINAE Kozár, subfam. n. Type genus: Foldicoccus Kozár, gen. n. The subfamily differs from other subfamilies by having umbelliform setae on the margin of the dorsum. FOLDICOCCINI Kozár, trib. n. The tribe may be characterised by two rows of the umbelliform setae on the dorsal margin. Foldicoccus Kozár, gen. n. Type species: Foldicoccus monikae sp. n. The genus has sclerotized plates on the dorsum. Some of them on the thoracic tergites altogether with umbelliform setae, some others with broad fimbriate setae. Foldicoccus monikae sp. n. (Fig. 3) Material examined — Holotype: female, Brasilia, Fazenda Aqua Azul, Maranhao Staatm, 02-04. 09. 1967. Leg. J. Balogh, No. 284, BRB 4 (this slide includes one 3rd instar larva, too). From the same collection there are three 1st instar larvae on one slide and on another slide one 2nd and one 3rd instar larvae. Paratypes: Two females (on one slide) from the same collection as the holotype. Four females, on three slides, these two slides contain larvae of 1st and 3rd instar, one more slide contains 1st and 2nd instar larvae, Brasilia, Belém, Para Staat, 18. 09. 1967. Leg. J. Balogh No. 310, BRB 29. Description of adult female — Mounted specimen (Fig. 3): Holotype, adult female 1.2 mm long, 0.6 mm wide. Antennae 3-segmented, 1st segment 48 pm long, 2nd segment 38 pm long, with a sensory pore, apical segment 72 pm long, with setose setae on all segments, apical segment, with two sensory setae 22 pm long, apical seta 88 pm long, with one short subapical seta 17 pm long. Venter: Labium 47 pm long. Stylet loop three times longer than labium. Legs: 1st coxa 64 pm long, trochanter-femur fused, 134, tibia-tarsus, not clearly divided, 115 pm long, claw 24, claw digitules hairlike, 2nd - coxa 74 pm long, trochanter-femur 144, tibia-tarsus 115, claw 24, claw digitules 8 pm long, 3rd - coxa 86 pm long, trochanterfemur 160, tibia-tarsus 128 pm long, claw 26, with hair-like setae. Legs covered with hair-, spine-like, and fimbriate setae (some of them wide brush-like), with clavate sensory setae near tibial sensorium on all legs; trochanter with two sensory pores on each surface. Thoracic spiracles (which should be on the venter) (exsertiles sensu Richard 1986) situated on the dorsum, 26 pm long. Fimbriate setae, broad clavate setae, and some hair-like setae, scattered in medial areas of thorax, and presented in rows on the abdominal segments. Bilocular pores 4 pm in diameter; scattered on both surfaces. Quadriloculars and simple pores absent. Tubular ducts absent. First two abdominal spir-
