Fig. 1 in Antennomere numbers in fireflies (Coleoptera: Lampyridae): unique patterns and tentative explanations

Fig. 1. Antennal diversity of fireflies is remarkable both in shape and in antennomere numbers. AeF: Diversity of shapes of 11-jointed antennae: A, filiform (Photuris femoralis); B, serrate (Lucidota atra); C, serrate and uniflabellate, flabella compressed along the major axis of antenna (Scissicauda disjuncta); D, filiform and uniflabellate, flabella compressed perpendicular to major axis of antenna (Cladodes illigeri); E, biflabellate and symmetric (Roleta sp.); F, biflabellate and asymmetric (Lucio blattinum). Arrow points one of the smaller branches. GeJ: Diversity of shapes of antennae with numbers other than 11. G, filiform (Microphotus angustus, 9 antennomeres); H, petaliform (Petalacmis sp., 9 antennomeres); I, uniflabellate (Amydetes fastigiata, 35); J, biflabellate (Araucariocladus hiems, 18 antennomeres). f: flagellum, p: pedicel, s: scape.
