FIGURE 4 in Antennal sensory organs of Scathophaga stercoraria (Linnaeus, 1758) (Diptera: Scathophagidae): ultramorphology and phylogenetic implications

FIGURE 4. SEM micrographs of coeloconic sensilla and clavate sensilla on the antennal funiculus of male Scathophaga stercoraria (Linnaeus, 1758). A. Distribution of coeloconic sensilla in the proximal region of antennal funiculus. B. Overview of distal region of antennal funiculus. C. Magnification of coeloconic sensillum. D. Magnification of clavate sensillum. E. Distal surface of clavate sensillum, showing pores on it. (Abbreviations: Ba I (basiconic sensillum I); Ba II (basiconic sensillum II); Co (coeloconic sensillum); Cl (clavate sensillum); Mt (microtrichia); Tr (trichoid sensillum). Scale bars: A–B. 15 µm; C–E. 2.5 µm.)
