Pseudosmittia sp. " Brazil "

( Figs 207–210 )

Material examined. BRAZIL: Amazonas State, Rio Maramá, North Mission San Antonio , A 491, 1 pupal exuviae, 24.i.1963, E.J. Fittkau ( ZSM) .

Pupa (n = 1). Total length 1.80 mm. Exuviae essentially colorless.

Cephalothorax ( Figs 207–208 ). Frontal apotome, thorax and wing sheath smooth. Frontal seta and median antepronotals each about 35 µm long. Distance between Dc 1 and Dc 2 59 µm, between Dc 2 and Dc 3 16 µm, between Dc 3 and Dc 4 5 µm.

Abdomen ( Figs 209–210 ). Tergite I bare; T II–IX with extensive shagreen, stronger anteriorly and posteriorly and with bare preapical band on T VIII. Sternites I–V bare, S VI–IX with anterolateral shagreen, weak on T IX. Tergal conjunctive III/IV with 12 spinules, IV/V with 22, V/VI with 32, VI/VII with 26 spinules. Sternal conjunctive IV/V possibly without spinules, V/VI with 42 spinules, VI/VII with 53 spinules. Anal segment without setae.

Remarks. This species from the Amazon area clearly belongs in the forcipata group. It differs from other associated pupae of the group by having spinules only on two sternal conjunctives.
