Comments: Ilyocryptus silvaeducensis paraensis has an occurrence range restricted to two locations in Northern Brazil ( Fig. 3E View Figure 3 ). This is the only Neotropical taxon that belongs to the silvaeducensis group. For further information regarding the morphology of this taxon and its differentiation from subspecies of other zoogeographical regions, see Kotov & Elmoor-Loureiro (2008).
