Zahlbr. Description. Swinscow and Krog (1981 , as P. pannosa ), Timdal and Krog (2001) . Distribution. North America ( Brako 1991 ), Africa ( Timdal and Krog 2001 ), Asia. Remarks. This species (Fig. 6A) was previously known from the type collection from North America (Louisiana), East Africa (Ethiopia, Kenya, Tanzania), and a few reports from Asia (Table 1). We here confirm its presence in Asia, based on DNA sequences from material from Sri Lanka compared with sequences from Kenya and Tanzania (Suppl. material 1: Fig. S1). Three chemotypes of this species are known ( Timdal and Krog 2001 ), differing in terpenoid patterns and presence of an unknown compound. Our two specimens from Sri Lanka belong in chemotype 3 of Timdal and Krog (2001) . The species is the phylogenetic sister to P. amazonica (Fig. 1). It is new to Sri Lanka. Figure 6.
