Genus Stictolecanium Cockerell

Stictolecanium Cockerell, 1902: 452 .

Type species: Lecanium ornatum Hempel, 1900: 421 . By original designation and monotypy.

This genus belongs to the Saissetiini (Coccinae) ( Hodgson, 1994) and has four species, two from Brazil and two from Argentina (Granara de Willink, 2006). The type species was described based on specimens from Eugenia jaboticaba (Myrtaceae) collected in Brazil. The new species, described below, shares the following features with S. ornatum (Hempel) , the type species of the genus: (1) dorsal pores arranged in a reticulated pattern; (2) marginal setae numerous; (3) ventral tubular ducts of two or more types in a submarginal band; (4) legs with tibio-tarsal scleroses; (5) spiracular pores with 5-loculi; (6) perivulvar pores with 10 loculi, present on mid areas of all abdominal segments; and (7) antennae 8 segmented.

The species differs from S. ornatum by the following combination of features (character states of S. ornatum in parentheses, taken from Hodgson (1994)): (1) cribriform plates absent (present), (2) stigmatic spine differentiated from marginal setae (not differentiated), (3) marginal setae of 2 types, i.e., bluntly spinose with knobbed apex, and sharply spinose (marginal setae very long and setose, with a flagellate apex), (4) ventral tubular ducts of 2 types (3 types), and (5) perivulvar pores absent from area mesad to each prothoracic coxa and near antennae (present mesad to each prothoracic coxa and with a single pore near each antenna).
