Adelpha serpa diadochus
Fairly common 700-1100 m. Attracted to bait.
Similar species: Similar to A. margarita (probably higher elevations; I have no Cusco records) and A. hyas diadochus but lines crossing veins in marginal markings (D and V), not just streaks parallel to veins.
Adelpha hyas viracocha
Uncommon 1000-1500 m. Attracted to bait.
Similar species: See A. serpa diadochus. A. margarita (I have no Cusco records) has a darkened area in the middle part of the VHW margin.
Adelpha aricia aricia
Uncommon 1500-2950 m. Puddles; attracted to bait.
Similar species: Lacks pair of white dashes DFW of A. alala negra.
Adelpha fabricia
Uncommon up to 850 m. Usually found inside forest; attracted to bait.
Similar species: Recalls several others, perhaps especially A. sichaeus, but the combination on VFW of a split post-discal spot in space 2 and a reduced submarginal spot (compared with those above and below it) in space 3 is unique.
Adelpha malea aethalia
Rare(?) up to 550 m. Usually found inside forest; attracted to bait and occasionally puddles.
Similar species: Has a split pale post-discal spot in space 2 VFW, like A. fabricia and A. capucinus capucinus, but lowest orange apical spot DFW is small to absent (like fabricia) and submarginal spot in space 3 VFW is the same size as those above and below it (like capucinus).
Adelpha boeotia boeotia
Fairly common up to 1350 m. Attracted to bait.
Similar species: Very straight and continuous dark orange line dividing discal and post-discal pale areas VFW is distinctive; many others have this line curved or broken, while A. cocala cocala lacks pale markings in post-discal area. See also A. jordani which has a superficially similar V pattern.
Adelpha ximena ximena
Unommon up to 1350 m. Attracted to bait.
Similar species: Outer edge of orange band DFW is scalloped and parallels the wing margin; compare this with superficially similar A. boreas boreas.
Adelpha erotia erotia
Uncommon up to 1500 m. Attracted to bait. Two forms with very different D patterns exist (see images); all the individuals I've seen in Cusco have the DFW with a solid white band and a separate orange apical patch. V is similar on both forms.
Similar species: Note the large, solid pale spot in space 3 VFW and the three bold rows of white markings on outer part of VHW. See very similar A. messana delphicola.
Adelpha messana delphicola
Rare(?) up to 550 m. Puddles; attracted to bait.
Similar species: Similar to several others; note solid spot in space 3 VFW, with an adjacent well-marked post-discal spot. Most similar to A. erotia erotia: the row of white dashes distal of the white band VFW is even width throughout, or widest at top, in messana; the 2nd and 3rd dashes from the top are widest in erotia.
Adelpha thesprotia
Uncommon up to 850 m. Puddles; attracted to bait.
Similar species: Not distinctive. No other species has a large solid pale patch in space 3 VFW with an faded adjacent submarginal spot other than A. attica (I have no Cusco records); attica has a broad, nearly solid band basal of the white band VHW among other differences.
Adelpha sichaeus
Common 750-1450 m. Puddles; attracted to bait.
Similar species: Similar to several others but note the very contrasting V pattern including a wide dark area distal from white band VHW. Cf especially A. justina valentina which is common in the same areas; it has a less contrasting V pattern, lacking a bold line separating discal and post-discal pale markings VFW.
Adelpha boreas boreas
Common up to 1350 m.; probably less common (absent?) in true lowlands. Puddles; attracted to bait.
Similar species: D recalls A. ximena ximena but note that the outer edge of the orange band DFW runs from post-discal area at costa to the tornus, not paralleling the wing margin as in ximena.
Adelpha cocala cocala
Fairly common up to 1050 m. Usually found inside forest; attracted to bait.
Similar species: VFW pattern, with the straight divide between pale discal and orange post-discal area, is unique; compare with A. boeotia boeotia. On D, 'bulged' appearance of orange band DFW can be useful.
Adelpha irmina tumida
Fairly common 850-2150 m. Attracted to bait; puddles.
Similar species: Very similar to A. zina irma; best told by VHW where zina has a more or less complete row of marginal white dashes and irmina has just three white spots near apex; irmina has V pattern generally more sharply marked and contrasting. See also A. salmoneus colada and A. saundersii which have obvious differences on V but can be very similar to irmina on D.
Adelpha saundersii saundersii
Uncommon at 2150 m., probably lower. Attracted to bait. Intergrades with helepecki might occur.
Similar species: Extensive yellow on V distinguishes saundersii from similar species. Subspecies helepecki has yellow in submarginal area VHW extending up to costa, not only below space 4 as in saundersii.
Adelpha saundersii helepecki
Fairly common 1100-1950 m. Puddles; attracted to bait.
Similar species: Extensive yellow on V, especially VHW, distinctive. See saundersii for differences between subspecies.
Adelpha coryneta
Locally fairly common 1500-2150 m. Restricted to drier valleys, though found in cloud forest within these areas. Puddles; attracted to bait.
Similar species: DFW with large, tapered orange apical patch is distinctive; note that the orange patch is separate from the white band, not touching as in A. cytherea cytherea. V is also unique.
Adelpha jordani
Uncommon up to 1100 m., probably more common in lowlands. Attracted to bait. I have twice encountered apparent hybrids with A. zina irma.
Similar species: V pattern vaguely recalls A. boeotia boeotia, but note rounded HW and single orange apical spot DFW.
Adelpha zina irma
Common 700-1350 m. Puddles; attracted to bait. Presence of orange apical spots DFW is variable. I have twice encountered apparent hybrids with A.jordani.
Similar species: V pattern plainer than similar species; see A. salmoneus colada, A. saundersii and especially A. irmina tumida, all of which have similar D pattern.
Adelpha justina valentina
Common 1050-1350 m. Attracted to bait.
Similar species: A. sichaeus is similar and common in the same areas, but has a wider orange band DFW and a more strongly marked V including an obvious dark line dividing pale discal and post-discal areas VFW. See also A. olynthia.
Adelpha olynthia
Fairly common, at times common, 1350-2200 m. Puddles; attracted to bait.
Similar species: White line HW is much narrower than similar species; compare especially with A. justina valentina.
