Plagaedessa maranhensis sp. n.

( Figs. 38–39 , 50–51, 52)

Etymology. Name refers to the locality where the specimen was collected.

Material examined (n=1): Holotype female. BRAZIL, Maranhão: 1 ♀, Bom Jardim, REBIO-Res. Biol. Gurupi. Armad. Luminosa Base. 05–15.VI.2010, J. C. Silva, J. A. Silva, A. A. Santos, T. T. A. Silva. ( MPEG).

Measurements. Total length: 17.7 mm; abdominal width: 8.9 mm; head length: 1.7 mm; head width: 3.2 mm; antennomeres length: I: 0.9; II: 1.6; III: 1.9; IV: 3.7; V: 4.2; pronotum length: 3.5 mm; pronotum width: 10.2 mm.

Diagnosis. Gonocoxites 8 with distal region rounded and strongly projected reaching almost half of the length of the plate; projection forming a U–shaped medial excavation ( Fig. 38 ). Gonocoxites 9 with posterior margin slightly notched ( Fig. 38 ). Protuberance of gonapophysis 9 larger than in the other species.

Discussion. Male unknown. This species can be easily recognized by the form of the gonocoxites 8 and 9. Females from the other species are quite similar and difficult to differentiate.
