Name
Leucochrysa camposi (Navás, 1933) – Wikispecies link – ZooBank link – Pensoft Profile
- Nodita camposi Navás, 1933: 197–8, Fig. 17 (Lectotype: MNHN, male, examined; original description: “Ecuador: Guayaquil, Julio de 1932. Campos R. Leg.”). Navás (1934b: 16)[1] [collection record: “Guayaquil (Ecuador), 1933. Campos leg.”; specimen in MNHN]; Penny (1977: 25)[2] [species list].
- Leucochrysa (Nodita) camposi (Navás). First combination in Leucochrysa (Nodita) apparently by Brooks and Barnard (1990: 277)[3] [species list]. Freitas and Penny (2001: 287)[4] [misidentified; see Leucochrysa (Nodita) azevedoi, above]; Oswald (2007)[5] [catalog listing, nomenclature]; Legrand et al. (2008: 121)[6] [lectotype designation, information on type].
- Nodita morenoi Navás 1934a[7]: 157–158 (Lectotype: MNHN, male, examined; original description: “Équateur, Quito, R. Benoist, 1930. Mus. París.”). Synonymized by Legrand et al. (2008: 154)[6]. Here: Synonymy reversed (see below).
Type material
The Nodita camposi lectotype, a male, is badly discolored, but its wings are in good condition, its body is mature, and the genitalia are well sclerotized. A female specimen collected one year later, at the same locality as the type, is also mature.
Diagnosis
Leucochrysa (Nodita) camposi can be distinguished from Leucochrysa (Nodita) azevedoi by its somewhat larger size and more robust appearance (see above) and genitalic characters (male and female) (Figs 8–10). In the male Leucochrysa (Nodita) camposi, the gonarcal arms are narrowly arched; the gonarcal arms extend perpendicularly from the gonarcal bridge, not laterally as in Leucochrysa (Nodita) azevedoi. The gonocornua are located distally on the gonarcal bridge, well outside the span of the mediuncus, and they extend laterally away from the gonarcal bridge. Like Leucochrysa (Nodita) azevedoi, the mediuncus is heavy apically and its beak is borne on a plate (arcessus) that bends back toward the gonarcal arch; however, the membrane extending from the beak does not have distinct arms or patches of setae, as are found on Leucochrysa (Nodita) azevedoi. The hypandrium internum is delicate and has a very narrow U-shape. The Leucochrysa (Nodita) camposi female can be recognized by its bulbous spermatheca, asymmetrical bursa that extends from its left side over the spermatheca and part of the bursal duct, and its highly coiled bursal duct that extends well into the sixth abdominal segment. The bursal glands are elongate, branching and ribbon-like.

Larvae and biology
Unknown.
Distribution
Currently known only from Ecuador (Guayaquil, Quito).
Adult specimens examined
In addition to the type listed above, we examined two female specimens from the type locality; both are in the MNHN. One was collected in 1933 and was reported by Navás (1934b: 16)[1]. The other specimen bears a determination label reading “Nodita Azevedoi Nav, P. Navás S.J. det.”; it was reported by Navás (1928: 111)[8]. The descriptions above are based on the male type and the female specimen reported by Navás in 1934.
Etymology
Navás named the species in honor of its collector, D. Francisco Campos R. of Guayaquil, Ecuador. Campos provided Navás with numerous lacewing specimens from Ecuador.
