Remarks

• Systematics: Gallacoccus heckrothi agrees with G. secundus and G. spinigalla in many characters but differs as follows: in the adult female the disc pores are of two types, the disc pores occur on the head as well as on the posterior portion of the body and some dorsal setae are geminate; in the adult male the papillae are tubercular, the antennae, legs, and genital capsule as well as the trunk are beset with papillae, the fifth antennal segment is provided with two knobbed setae and the prescutum is relatively short. Some of these characters, when combined, may have generic value, justifying the erection of a new genus for this species, but it is tentatively referred to Gallacoccus (Takagi, 2001).
• Structure: Adult female globular, simplified in structure. Quinquelocular pores variable in size, strewn about body on both surfaces except on head, where they are limited to the dorsal surface; broadly scattered in prothoracic region on dorsal surface and also anteriorly to anus; densely strewn between anus and vulva and laterally to vulva, none anteriorly to vulva. Derm with spicules on some segments anterior to anus. Adult male with head very small, abdomen about as long as thorax, gradually narrowing posteriorly on distal half (Takagi, 2001).
• Biology: Galls produced by this species showed no processes on the external surface. One dry gall found was elongate globular, 3.8 cm long and 2.8 cm wide, glabrous on the external surface, with the distal end produced to form a short tube for exit. The gall was similar to galls produced by G. secundus, though the latter is not smooth on the external surface (Takagi, 2001).
• General Remarks: Detailed description of 1st instar female, adult female, 1st and 2nd instar male and adult male by Takagi (2001).
