Coxicoccus Kozár (in Kozár & Konczné Benedicty 2008: 118–119)
Type species: Coxicoccus foldi Kozár & Konczné Benedicty 2008: 119–121 .
Generic diagnosis. Adult female ( Fig. 18 View FIGURE 18 ). Dorsum. With spine-like setae of more or less 1 size. Macrotubular ducts narrow, long, inner ductule ending in flower-like terminal gland; present throughout. Microtubular ducts long with bifurcate orifice, few but often associated with base of dorsal spinose setae. Anal lobes well developed, dorsal surface with 3 strong, curved spinose setae. Anal ring sclerotised, not well developed, with 8 setae, each twice as long as width of anal ring; anal ring pores few. Median plate absent. Margin. Not differentiated. Venter. Setae capitate on posterior abdominal segment; suranal setae also capitate and longer than length of anal lobes; ventral surface of each anal lobe with 1 short apical seta + a capitate subapical seta. Macrotubular ducts sparse throughout. Microtubular ducts submarginal. Cruciform pores absent. Loculate pores present medially, mainly on abdomen. Antennae 7 segmented. Frontal lobes and antennal tubercles absent. Labium 1 (?) segmented; basal segment with 1 pair setae. Legs long, tibia shorter than tarsus; all coxae with spinulae; metacoxae with small translucent pores. Vulva present between abdominal segments VII and VIII. (Modified after Kozár & Konczné Benedicty, 2008).
Host plant unknown.
Comment. Kozár & Konczné Benedicty (2008) state that this genus is close to Eriococcus and Acanthococcus . It resembles Eriococcus in having: (i) only 1 seta on basal segment of labium; (ii) long microtubular ducts with a bifurcate orifice; and (iii) in lacking cruciform pores. It differs in: (i) absence of enlarged tubular ducts; (ii) absence of frontal lobes; and (iii) presence of translucent pores on metacoxa, femur and tibia. It resembles Acanthococcus in having: (i) enlarged spine-like setae on dorsum; and (ii) micro- and macrotubular ducts; it differs in the absence of: (i) cruciform pores; (ii) frontal lobes; and (iii) a median plate, and presence of (iv) only 1 pair of setae on basal segment of labium. In addition, it differs from both genera in having clavate setae posteriorly on the venter. Note that the vulva lies between VII and VIII, not as illustrated in Kozár & Konczné Benedicty (2008).
Coxicoccus is a monotypic genus known only from Chile. For a description of the adult female of the type species, see Kozár & Konczné Benedicty (2008) .
