Leucochrysa azevedoi Navás, 1913 – Wikispecies link – ZooBank link – Pensoft Profile
- Leucochrysa azevedoi Navás, 1913: 97; Type: missing; original description: “Brasil: Rio de Janeiro, Agosto de 1911. R.P. Joaquín da Silva Tavares S.J. (Col. m.)”. Navás (1912–1913: 303)[1] [species list].
- Nodita azevedoi (Navás). First combination in Nodita by Navás (1928: 111)[2] [collection record: Guayaquil, Ecuador, May 1926, probably misidentified; see below]. Navás (1929: 859)[3] [collection record: Prov. de Rio de Jan., Coll. v. Bönninghausen, 20-X-1906, M. H., specimen probably destroyed]; Penny (1977: 25)[4] [species list].
- Leucochrysa (Nodita) azevedoi Navás (Brooks and Barnard 1990: 277[5]) [species list]; Oswald (2007)[6] [catalog listing, nomenclature]; Legrand et al. (2008: 117)[7] [probably Nomen Dubium]; Mantoanelli et al. (in press)[8] [larval descriptions]. Here: confirmed as a valid species.
Type Material
The original type remained in Navás collection (Navás 1913[9]: 97); however, it does not exist in the Navás collection at the Natural History Museum of Barcelona now (Monserrat 1985[10]: 240). Also, Legrand et al. (2008: 117)[7] were unable to find it in the Muséum national d’Histoire naturelle, Paris (MNHN). It is reasonable to assume that the specimen has been destroyed; therefore, Legrand et al. (2008)[7] considered the species a Nomen Dubium.
Recently we attempted to identify a Leucochrysa (Nodita) species from orchards in northern Rio de Janeiro State. Using the key by Freitas and Penny (2001)[11], we identified the specimens as Leucochrysa (Nodita) camposi, a species that was described from coastal Ecuador; our specimens matched the drawings and description included with the key. However, comparison of our specimens with the type of Nodita camposi showed significant differences.
Earlier, we had noted that Navás had confused Leucochrysa (Nodita) camposi and azevedoi (see Legrand et al. 2008[7]: 116). That is, he had labeled a specimen of Leucochrysa (Nodita) camposi in the MNHN as Nodita azevedoi; this specimen had been collected from the Nodita camposi type locality in 1930. [Note: Navás may also have similarly misidentified another specimen collected from the same locality in 1926 (Navás 1928[2]: 111), but we have not seen that specimen.]
Navás’s errors then led us to consider whether our specimens could be Leucochrysa (Nodita) azevedoi. Indeed our specimens were collected in the state of Rio de Janeiro, where Leucochrysa (Nodita) azevedoi was originally collected; moreover our specimens fit Navás’s original description of Leucochrysa azevedoi well. Although Navás’s type of Leucochrysa azevedoi is missing, the similarities in external features, coupled with his confusion of the two species, give us confidence that Navás’s original description applies to the specimens we have at hand from northern Rio de Janeiro State.
As a result of our studies and the correction of Navás misidentifications, we now consider that Leucochrysa (Nodita) azevedoi ranges throughout coastal Brazil [and probably also into the state of Pará] and that Leucochrysa (Nodita) camposi occurs on the west coast of northern South America (currently known only from Ecuador). Now, to stabilize the nomenclature of these species, we designate as the Leucochrysa azevedoi neotype, a specimen (male) from the Brazilian state where the original type specimen was collected. Its labels read: (1) “Brazil: R[io de] J[aneiro], Campos dos Goytacazes, Est. Exp. PESAGRO (Estação Experimental da Empresa de Pesquisa Agropecuária do Estado do Rio de Janeiro) [21°44'55"S, 41°18'30"W], 06/IV/2002”; (2) “G. S. Albuquerque, Collector”; (3) “NEOTYPE Leucochrysa azevedoi Navás 1913[9], desig. C.A. Tauber, G.S. Albuquerque 2010.” In the Coleção Entomológica Pe. Jesus Santiago Moure (Universidade Federal do Paraná, Curitiba, PR, Brazil).
Diagnosis
Externally, Leucochrysa (Nodita) azevedoi adults closely resemble several Leucochrysa (Nodita) species that have a red to reddish brown dorsolateral stripe on the scape, dark brown to black ventrolateral marks on the basal flagellomeres, red to reddish brown marks on the sides of the raised portion of the vertex, a darkened section in the middle of the Radial sector (forewings and hindwings), and darkened terminal veinlets along the posteroapical margin of the hindwings (Figs 1A, 2–3). Leucochrysa (Nodita) azevedoi is slightly smaller than many of these species, including Leucochrysa (Nodita) camposi and Leucochrysa (Nodita) morenoi (wing length 17.7–19.5 mm versus ~21.3–21.6 for Leucochrysa (Nodita) camposi and morenoi), but it can only be identified with accuracy by its genitalic characters (male and female) (Figs 4–6). In the male Leucochrysa (Nodita) azevedoi, the gonarcal arms are broadly spread; they extend almost the full width of the segment. The gonocornua are located mesally on the gonarcal bridge, well within the span of the mediuncus, and they are directed upward from the bridge, not laterally from the bridge as are the Leucochrysa (Nodita) camposi gonocornua. The mediuncus is heavy; the beak is borne on a posteriorly projecting ventral plate (arcessus) that angles back towards the gonarcal arch; the beak is broad and blunt, and the membranous arms extending laterally from below the beak are rounded and each bears a lateral patch of setae. The hypandrium internum has a broad V-shape. Females can be recognized by their tubular spermatheca, small bursa, relatively small, fluted bursal duct. The bursa has two elongate, branched, tubular glands attached to its dorsal surface, and the subgenitale is heavy-based; the terminus has a thick neck, paired short, dorsal lobes and a short protrusion.

Larvae

Biology
This species has been collected in orchards in the states of Rio de Janeiro, São Paulo, Mato Grosso and Rio Grande do Sul, in some cases in relatively large numbers. Its seasonal occurrence in orchards of coastal Brazil was assessed (Multani 2008[12]).
Distribution
Currently known only from Brazil. We have seen specimens from the States of Rio de Janeiro, Matto Grosso, and São Paulo [also see Freitas and Penny 2001[11], as Leucochrysa (Nodita) camposi]. Probably, the species also occurs in the State of Pará. [Note: Adams (1987)[13] considered a specimen that he studied from Pará (illustrated in Fig. 18) to be an abnormal variant of Leucochrysa (Nodita) amazonica (Navás). It is not clear why he did so; Navás’s description of Leucochrysa (Nodita) amazonica was based on a single teneral male from the lower Amazon. Our study shows that Adams’ figure of the specimen from Pará is typical of Leucochrysa (Nodita) azevedoi.]
Variation
See images on our project site at www.morphobank.org. In teneral males, S8 and S9 are only partially fused; the segments are fully fused, but well demarcated in mature males. When teneral, the gonarcus is thin and delicate; the gonocornua are small and closely aligned, adjacent to the mediuncus; and the setose lateral extensions below the beak of the mediuncus are not visible, but the beak is distinct.
In addition to the specimens listed below, we examined one specimen (a male) from the State of Rio Grande do Sul. This specimen’s background color and markings are lighter than those of the other specimens; in addition, the beak on its mediuncus is sharp and straight, not blunt and decurved as in Leucochrysa (Nodita) azevedoi. A determination of whether this specimen represents a separate species or a variant population of Leucochrysa (Nodita) azevedoi awaits the availability of additional specimens.

Etymology
Latinized proper name, genitive. Navás named the species in honor of Ignacio de Azevedo (1528–1570), a Portuguese Jesuit who labored in Brazil and was killed along with 39 Jesuit companions, while sailing near the Canary Islands on a return voyage from Rome to Brazil. They are known as the “Fourty Martyrs of Brazil”.
