Soares, Matheus M. M. & Capellari, Renato S., 2020, Review of the Neotropical genus Pseudosympycnus (Diptera: Dolichopodidae) with description of six new species from Brazil and Peru, Zootaxa 4881 (2), pp. 231-256 : 242-243

Pseudosympycnus latipes (Parent)

( Figs 4 , 24, 25 , 49, 50 , 67 , 86 )

Sympycnus latipes Parent, 1930: 23 , figs 28–30. Type locality: Taperinha farm, Santarém, Pará, Brazil.

Diagnosis (male). Metepimeron yellow ( Fig. 4 ). Femora mostly yellow, except femur I brownish ( Fig. 4 ). Tibia I not strongly compressed (only slightly thicker than tibiae II and III). Tarsus I ( Fig. 49 ) with It 1–2 brown and It 3–5 white: base of It 2 with brush of compacted stout dorsal setae directed forward and followed by 3 stout curved setae, apex with dorsal and anterodorsal stout setae; It 3 with dorsal projection, overlapping base of It 4 and with 3 stout dorsal setae at base and dorsal row of white slender setae. Tarsus II unmodified. Tarsus III ( Fig. 50 ): IIIt 3 with 4 posterior setae longer than podomere length and curved at apex.

Material examined. BRAZIL. Acre, Mâncio Lima, Parque Nacional Serra do Divisor, Malaise , 5.x.2007, L. Menezes (1 Ƌ, INPA) . Amapá, Serra do Navio , 18.v.1989, I.S. Gorayeb, Armadilha Suspensa 6m (1 Ƌ, MPEG) .

Remarks. Robinson’s (1967) identification key leads P. latipes to couplet 3, which includes the species without whitish distal joints on male fore tarsus. Nevertheless, Parent’s (1930) original description clearly states “ tarse I, articles 3, 4 et 5 blancs ” (“fore tarsus, joints 3, 4 and 5 white”), which is also confirmed after examination of photographs of the type (NHMW). Apparently P. latipes and P. albipalpus are switched in the couplets of the identification key.

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