Remarks. Belonopteryx can easily be distin- guished from other Chrysopidae by the lanceolate wings, marked with two black longitudinal stripes, the concave costal margin and absence of an intra- median cell. It differs from most Belonopterygini in primitively lacking parameres but retaining entoprocessus and in having extraordinarily dense microtholi. The genus is probably most closely related to Nacarina, species of which also lack parameres, but which, like Belonopteryx, have only three rows of setae on the flagellar segments, an unstable venation with many forked and irregularly placed crossveins, and a short second medial cell. Belonopteryx is apparently unique among the Chrysopidae in having a broad but untoothed left mandible. Due to the rarity of specimens of B. arteriosa we have not made any head preparations so have been unable to examine the right mandible but it is unlikely that this possesses a tooth either. Biology.
