Fig. 3 in New insights in the taxonomy of Lepismatidae (Insecta, Zygentoma) with an updated key to genera and future challenges

Fig. 3. Pronged sensilla of the apical article of the maxillary palp of some subfamilies of Lepismatidae Latreille, 1802, SEM photographs. A. Three pronged sensilla in Heterolepisma sp., with short and wide base and several (8–9) finger-like projections. B. One pronged sensilla (arrow) in Allacrotelsa kraepelini (Escherich, 1905), with long base and few finger-like projections. C. One of the three narrow multipronged sensilla of the ultimate article of the maxillary palp of Visma spp. They are probably homologous with the sensilla seen in Allacrotelsa Silvestri, 1935 and other Lepismatinae Latreille, 1802 but the other two have been lost. Scale bars: A = 0.1 mm; B = 50 μm; C = 25 μm.
