(Modified from Kondo 2010; Kondo and Williams 2009)

1. Anal plates located near mid dorsum; ventral tubular ducts absent .......................................... 2

– Anal plates not located near mid dorsum, generally found at about 1/5 of body length from posterior margin; ventral tubular ducts present or absent .................................................................... 3

2(1). Anterior spiracular pore band incomplete, not extending to margin, posterior spiracular pore band extending to margin; marginal setae cylindrical, peg-like; stigmatic setae absent .......... ....................................................................................................... Cyclolecanium Morrison View in CoL

– Anterior spiracular pore band complete, extending to margin; marginal setae sharply to bluntly spinulose, not peg-like; stigmatic setae present, totaling 2-7 ..................................................... .......................................................................................... Foldilecanium Kondo , gen. nov.

3(1). Stigmatic clefts deep; dorsal sclerotized plates associated with each spiracle ............................... ................................................................................................................ Cryptostigma Ferris View in CoL

– Stigmatic clefts shallow or absent, or rarely deep; without dorsal sclerotized plates associated with each spiracle ..................................................................................................................... 4

4(3). Dorsal microducts around body margin conspicuously larger than rest of microducts on dorsum .............................................................................................................. Octolecanium Kondo

– Dorsal microducts around body margin not conspicuously larger than rest of microducts on dorsum .................................................................................................................................................. 5

5(4). Large bilocular pores (probably macroducts), present in 1 or 2 small groups anterior to anal plates; marginal setae slender, sharply spinose, with tips mostly pointed, but some with lanceolate, or bifurcate apices, arranged in 1 or 2 rows, numerous (distance between each marginal seta less than half the length of a seta) .......................... Aztecalecanium Kondo and Williams

– Groups of large bilocular pores or macroducts absent from area anterior to anal plates; marginal setae variable, arranged in 1 row, not as numerous (distance between each marginal seta more than the length of a seta) ......................................................................................................... 6

6(5). Preopercular pores absent; dorsum with dense pattern of invaginated bilocular microducts; stigmatic setae absent ................................................................ Pseudophilippia Cockerell View in CoL

– Ventral tubular ducts present at least around perivulvar area .................................................. 9

8(7). Dorsum of slide-mounted specimens with a dense pattern of microducts. Young adult females in life covered by a white cottony to powdery wax, although this powdery wax disappears in old specimens. Perivulvar pores mostly with 5 loculi and one central loculus ................................ ............................................................................................................... Bombacoccus Kondo

– Dorsum of slide-mounted specimens without a dense pattern of microducts. Adult females in life covered by a thin layer of glassy wax. Perivulvar pores mostly with 7 or 8 loculi and with 2 or 3 central loculi .......................................................................................... Akermes Cockerell View in CoL

10(9). Ventral tubular ducts located around vulva and mediolaterally on abdomen; dorsal setae lanceolate; stigmatic clefts deeply invaginated ................................................ Megasaissetia Cockerell View in CoL

– Ventral tubular ducts located around vulva and often also on posterior abdominal segments, but absent mediolaterally on abdomen; dorsal setae generally sharply spinose, rarely lanceolate; stigmatic clefts absent or shallowly invaginated ................................ Toumeyella Cockerell View in CoL
