Xenylla mucronata Axelson, 1903 — Figs. 85-89
Xenylla mucronata Axelson, 1903
Axelson's (1912, pls. iv and v) figures of this species deal with the furcula and anal spines. Specimens from BMNH Boerner's collection have been used for the figures included here and these add considerably more detail for the identification of this species.
Notes: Sensory structures of Ant IV are as drawn in Fig. 85. The SO Ant III (Fig. 87) is similar to that of X. longicauda Folsom with the two inner small sense rods completely hidden behind a high cuticular fold. The two tenent hairs of each foot of equal length (Fig. 86); papillae of anal spines contiguous; mucro incompletely separated from dens which bears two simple setae only on posterior face (Fig. 89). The species X. longicauda and X. mucronata are very similar differing mainly in the shape of the mucro and the extent of its lamella, and by the form and degree of separation of the anal spines and their papillae.page 18
