Pseudogaurax longilineatus Sabrosky, 1949

( Fig. 15 )

Material examined. BRAZIL. Pará: Belém, Research Campus of Museu Paraense Emílio Goeldi , 1°27’06.5”S 48°26’38.8”W, 08.IX.2016, leg. F.S. Carvalho-Filho, reared from pupa of Cicinnus infected with an entomophagous fungus ( 1 male) .

Puparium ( Fig. 14 ). Reddish brown. Elongated, cylindrical, parallel-sided, slightly dorsoventrally flattened, apically and posteriorly truncate. Dorsal surface with some long transverse wrinkles, without spinules and setulae. Posterior spiracle well-developed, placed on an elongate tubular projection.

Distribution. Brazil ( Ceará, Minas Gerais, Pará, Rio de Janeiro, Roraima).

Natural history. The analyzed specimen was obtained from pupae of Cicinnus Blanchard sp. ( Mimallonidae ), one of which was infected with an entomophagous fungus ( Fig. 16D ). This species has been previously reared from mantid oothecae ( Sabrosky 1949, Travassos & Carrera 1949), evidencing that it utilizes a variety of host species from different orders and developing stages, as previously documented for other species of Pseudogaurax (Banes et al. 1992) .
