Key to separate the known species of Stictolecanium Cockerell

(Adapted from Granara de Willink (2006))

1. Stigmatic spines differentiated from marginal setae. Dorsal reticulation partial or obscure, not covering entire body ...................................................................................................................................................................................... 2

- Stigmatic spines not differentiated from marginal setae. Dorsal reticulation formed by propercular pores covering entire dorsum ............................................................................................................................................................... 3

2. Cribriform plates scattered over body surface. Reticulation pattern on dorsum when present, formed by preopercular pores restricted to margin only .......................................................... Stictolecanium entrerrianum Granara de Willink

- Cribriform plates absent. Reticulation pattern formed by preopercular pores restricted to mid-areas of dorsum only. ....................................................................................................... Stictolecanium cranstoni Kondo & Gullan sp. nov.

3. Preopercular pores on abdomen only. Marginal setae slender, long, with a flagellate apex. Legs with tibio-tarsal scleroses ......................................................................................................................... Stictolecanium ornatum (Hempel)

- Preopercular pores extending anteriorly to thorax. Marginal setae slender, spiniform or setose. Legs without tibiotarsal scleroses............................................................................................................................................................... 4

4. Clear marginal areas very broad, approximately twice as broad as long, delineated by circular pores, cribriform plates and setae that form lines. Perivulvar pores present on abdomen but absent on thorax ........................................ ............................................................................................................................... Stictolecanium convexum (Hempel)

- Clear marginal areas smaller, about as broad as long, delineated by broad bands formed by numerous pores, cribriform plates and setae. Perivulvar pores present on both abdomen and thorax ............................................................... ......................................................................................................
