Pseudosympycnus albipalpus (Parent)

( Figs 1 , 16, 17 , 42, 43 , 86 )

Sympycnus albipalpus Parent, 1930: 22 , figs 25–27. Type locality: Taperinha farm, Santarém, Pará, Brazil.

Diagnosis (male). Metepimeron yellow ( Fig. 1 ). Femora entirely yellow ( Fig. 1 ). Tibia I not compressed ( Fig. 1 ). Tarsus I ( Fig. 42 ) brown, except It 1 yellow: It 2 with 2 dorsal bristles at apex; It 3 twice as long as It 4; It 4–5 laterally flattened, with It 5 slightly longer than It 4 and with posteroventral row of curved setae. Tarsus II unmodified. Tarsus III ( Fig. 43 ): IIIt 3–4 with posterior and posteroventral rows of setae decreasing in size towards apex.

Remarks. Species with “distal joints of male fore tarsus partly compressed, whitish” run to couplet 2 of Robinson’s (1967) key. According to the original description and after examination of photographs of the type (NHMW), that is not the case for P. albipalpus , which has brown fore tarsus. Based on characters listed in couplet 1 of Robinson’s key, we suspect that P. albipalpus and P. latipes were simply switched in the key entries.

Material examined. BRAZIL. Amapá, Serra do Navio , 18.v.1989, Armadilha suspensa 1,6 m, A.L. Henriques (1 Ƌ, INPA) .

Distribution. Brazil (States of Amapá and Pará) ( Fig. 86 ).
