Remarks

• Systematics: Miller & Stocks (2022)designated a lectotype from the series collected by G.F. Ferris in 1926. It is in the Bohart Museum at UCD. In addition, there are 9 paralectotypes, some of which were used by Ferris for the line drawing; others were used for the original description of the gall and were mounted after the original description.
• Structure: Adult female is membranous and approximately circular when mounted (Ferris, 1957c). Slide-mounted adult female with: antennae reduced to unsegmented tubercles; legs absent; anal ring represented by minute area of sclerotization with 1 pair of small setae; with pores near spiracles; small setae; tubular ducts absent; minute circular pores scattered over body (Ferris, 1957b).
• Biology: This species forms galls on the small twigs of its host. These galls involving the petioles of several leaves, almost globular (Ferris, 1957c). Carpochloroides mexicanus was found in galls that contained not only this species but also numerous specimens of Carpo. eugeniae. In the original description of Carpo. mexicanus, Ferris (1957: 84) described it in the field as follows: “Forming gall on the small twigs of the host, these galls involving the petioles of several leaves, almost globular and attaining a length of as much as two cm. There must be some opening to this gall but this is extremely obscure.” It seems likely that Carpo. mexicanus is not the species that induces the galls. (Miller & Stocks, 2022)
