Morphology and morphometry of Lycaenid eggs (Lepidoptera: Lycaenidae) Munguira, Miguel L. Martín, José García-Barros, Enrique Shahbazian, Gayaneh Cancela, Juan Pablo Zootaxa 2015 3937 2 201 247 b452e628-a562-4ab1-a962-3dd71f61cde6 Reichenbach Reichenbach [238,481,1590,1616] Polychaeta Orbiniidae Aricia Animalia Lepidoptera 27 228 Annelida genus  ( Fig. 20and 21A, B)  The annular zone of the species from this genus is small and formed by cells of smooth surface, only occasionally bearing small ridges in  Aricia nicias(Meigen)( Fig. 20A, B) and  A. cramera(Eschscholtz)( Fig. 20E, F). This contrasts with the transition zone in which the surface of the cells is porous and the cell walls have a rough texture. Cells in this zone are organized in a regular spiral pattern that is more evident in  Aricia montensisVerity( Fig. 21A, B). In  A. niciasthe tubercle-aeropyle area has well developed ridged tubercles and cells with three or four sides, which adjoin together in groups of five to seven. The size of the tubercles is large in  A. nicias, intermediate in  A. montensisand short in  A. crameraand  A. morronensis(Ribbe)(20C, D). In the latter species this trait is variable in the different areas and tubercles can be larger than in the pictured specimen (see Munguira & Martín 1988; Munguira 1989). Tubercles are also crowned with aeropyles at their tips in all the species of the genus.  A. crameraalso differs from the eggs of the other species by the higher number of cells, making it quite similar to the egg of  A. agestis,while that of  A. montensisresembles  A. artaxerxes(Fabricius). The egg of  A. agestisand  A. artaxerxeshas been described in detail by Smyllie (2001).
