One of the morphs (the "brown-spotted" morph) is indistiguishable from the widespread species Leucochrysa (Leucochrysa) longicornis (G. Gray in Cuvier, 1832) and the second morph (the "white-spotted" morph) is identical to another Argentinian species, Leucochrysa (Leucochrysa) boxi Navas, 1930. These observations generated a number of nomenclatural changes: (1) The oldest of the three names, L. (L.) longicornis (= Hemerobius longicornis), is a secondary homonym of a Linnaean species described in 1764 and therefore is unavailable for Gray's species. (2) Thus, by priority, L. (L.) boxi becomes the valid name for the polymorphic species. (3) Leucochrysa (L.) loretana becomes a synonym of L. (L.) boxi. (4) The above three names are stabilized by the designation of primary types for each of the species, and by other nomenclatural actions. Specifically, (a) a lectotype is designated for Hemerobius longicornis G. Gray and, as First Revisers, we selected the species name from among two that were published in the original description; (b) a lectotype is designated for Leucochrysa boxi Navas; and (c) a neotype is designated for Leucochrysa loretana Navas. Finally, the L. (L.) boxi adult is redescribed (both morphs, as well as the male and female genitalia); the larvae (all instars) are described; and aspects of the biology ofthe species (geographic variation in the polymorphism and a new record of ectoparasitism) are presented.

One subspecies, M. h. theodorus Fruhstorfer,inhabits Amazonian moist forests in the western and northern parts of the country. Another subspecies, M. h. coelestis Butler, is common in moist cloud forests (Bolivian Yungas), but also occurs to the North and North-East. We describe a new subspecies,M. h. prometa ssp. nov., from Southern Andean Yungas. Transition zones between theodorus and coelestis are highlighted, where specimens exhibiting intermediate phenotypes were collected. The pattern of geographic transition from M. h. coelestis to M. h.prometa needs to be documented. M. h. prometa inhabits sub-humid, semi-deciduous forests, whereas M. h. theodorus and M. h. coelestis live in rainforests. M. h. coelestis populations are found from less than 100 m to more than 1600 m a.s.l.; M. h. theodorus has been collected at more than 1000 m a.s.l.; and M. h. prometa between 500 m and 1400 m a.s.l.. Therefore, Bolivian M. helenor populations are distributed throughout a wide range of ecological contexts: we discuss the habitat plasticity of the species in light of available knowledge of its geographical distribution and habitats in the Neotropical Region.
