Genus Coccus Linnaeus, 1758 

Type species: Coccus hesperidum Linnaeus, 1758  , designated by Opinion 1303 (1985). Diagnosis. Dorsal setae spinose, pointed, blunt or cylindrical ( Figs 17C View Figure , 19B View Figure , 23D View Figure , 25E View Figure , 27D View Figure , 29A View Figure ) (except in C. formicarii  , in which they are setose, Fig. 21C View Figure ). Marginal setae with pointed or fimbriate apices ( Figs 17J View Figure , 19J View Figure , 20C View Figure , 21B View Figure , 23M View Figure , 25A View Figure , 26C View Figure , 27B View Figure , 28C View Figure , 29I View Figure ). Venter with tubular ducts usually present on medial area of thorax or distributed in submarginal area ( Figs 17G View Figure , 19F View Figure , 21I View Figure , 23L View Figure , 25M View Figure , 27K View Figure , 29L View Figure ); and legs each with a tibio-tarsal articulatory sclerosis ( Figs 22E View Figure , 23I View Figure , 24E View Figure , 25L View Figure , 26E View Figure , 27H View Figure , 28F View Figure , 29M View Figure ) (except in C. capparidis  and C. formicarii  , Figs 17H View Figure , 20E View Figure , 21H View Figure ) ( Hodgson 1994; Wang & Feng 2012a).

Remarks. Coccus  is a large genus, comprising about 111 described species from all zoogeographical regions ( García Morales et al. 2016). Adult females of the genus are easily recognized by the presence of ventral tubular ducts mainly in the medial area of the thorax and legs each with a tibio-tarsal articulatory sclerosis ( Hodgson 1994).
