Eriobalachowskya Kozár

Eriobalachowskya Kozár (in Kozár & Konczné Benedicty, 2008: 121–123).

Type species: Eriococcus valenzuelae Balachowsky 1959: 363–365 .

Generic diagnosis. Adult female ( Fig. 19 ). Occuring on the leaves of Inga sp. in a coffee plantation. Body of adult female broadly oval, red, and covered with a pure white ovisac. Dorsum. Dorsal setae all spine-like, of rather variable size, each conical, with acute or slightly rounded apices. Macrotubular ducts absent. Microtubular ducts with a characteristically-shaped orifice, a long outer ductule and a filamentous inner ductule, common throughout. Anal lobes well developed, inner margins sclerotised and serrate; dorsal surface with 3 strong spinose setae; ventral surface with 4 setose setae. Anal ring sclerotised and well developed, with 8 anal ring setae, each twice as long as width of anal ring; anal ring pores few. Median plate rather large, of characteristic shape and sclerotised. Margin. Not demarcated. Venter. Setae of 2 types: (i) setose setae, each quite long, mainly present medially and submedially, and (ii) short spinose conical setae, much smaller than those on dorsum, present in large segmental clusters submarginally, and also submedially on thorax. Macro- and microtubular ducts absent. Cruciform pores numerous along margins. Quinquelocular pores frequent throughout. Antennae 8 segmented. Frontal lobes absent but antennal tubercles present. Labium 2 segmented, basal segment with 2 pairs of setae. Stylet loop long. Legs long, tibia shorter than tarsus; coxae of all legs with spinulae; posterior coxae with numerous translucent pores. Claw with denticle. (Modified after Kozár & Konczne Benedicty, 2008).

Known from Fabaceae .

Comment. Eriobalachowskya is a monotypic genus known from Colombia and Ecuador. According to Kozár & Konczné Benedicty (2008), Eriobalachowskya differs from all other eriococcid genera in: (i) having 8-segmented antennae; (ii) microtubular ducts with a particularly large and unusually-shaped dermal orifice; and (iii) a median plate swollen basally and with a pointed apex. It is somewhat similar to Acanthococcus , Eriococcus and Gossyparia in having enlarged, spine-like setae on the dorsum but differs in; (i) absence of macrotubular ducts; and (ii) presence of frontal tubercles.
