Etymology. This species is dedicated with much pleasure to Janice Peters who continuously encourages and helps us with the study of Polymitarcyidae, especially Campsurus.

Distribution (Fig. 179). Colombia and Brazil (Amazonas).

Diagnosis. Campsurus janae sp. nov. is known from male adults only. It can be distinguished from other species of Campsurus by: 1) posterior margin of male abdominal sternum IX truncated (Figs. 75); 2) pedestal almost touching each other medially, strongly elongated, parastylus short, broad and rounded apically, inner corner strongly projected (Fig. 75); 3) base of main lobe of penes strongly expanded laterodorsally (Fig. 76), penes narrowing abruptly on apical half, main lobe of penes apically pointed and curved ventrally; secondary membranous lobe relatively short and cylindrical; 4) small size (length of male fore wings 6.5 mm).

Discussion. Campsurus janae sp. nov. is similar to C. pereirae sp. nov., but the extremely large and elongated pedestal of C. janae sp. nov. easily differentiates it. Campsurus janae sp. nov. is described as a pharate male imago (still inside the subimaginal cuticle), but the characteristic genitalia are sclerotized and in their final configuration.
