Anthrenus (Anthrenus) festivus Erichson, 1846 ( Figures 4–6 View FIGURE 4 View FIGURE 5 View FIGURE 6 )
A total of 34 A. festivus were dissected (27♁♁ and 7♀♀). Examples of A. festivus habitus (dorsal aspect) ( Figure 4A View FIGURE 4 ), ventrites ( Figure 4B View FIGURE 4 ), and antenna ( Figure 4C View FIGURE 4 ) are illustrated. All data were normally distributed and homoscedastic. Male BL = 2.417 ± 0.122 mm (mean ± standard deviation); female BL = 2.529 ± 0.115 mm. Male BL was significantly smaller than female BL (t 31 = 2.17, p = 0.038). 95 % of male BL would be expected to fall between 2.17–2.67 mm (study sample minimum and maximum = 2.05 mm and 2.65 mm, respectively). 95% of female BL would be expected to fall between 2.25 mm and 2.81 mm (study sample minimum and maximum = 2.40 mm and 2.70 mm, respectively). Body width/body length (BW/BL) was calculated as a measure of body shape. Male BW/BL = 0.722 ± 0.016; female BW/BL = 0.709 ± 0.004. Male BW/BL differed marginally but significantly from female BW/BL (t 31 = 2.08, p = 0.46) indicating that males had a slightly rounder profile than females. 95% of male BW/BL would be expected to fall between 0.689 –0.755 (study sample minimum and maximum = 0.688 and 0.750, respectively). 95% of female BW/BL would be expected to fall between 0.700 and 0.718 (study sample minimum and maximum = 0.703 and 0.714, respectively). Figure 4C View FIGURE 4 shows a typical example of an A. festivus antenna. For the antenna shown in Figure 4C View FIGURE 4 , AL = 161 µm and AW = 121 µm, AL/AW = 1.33.
Figure 5A and 5B View FIGURE 5 show an A. festivus aedeagus dorsal and ventral aspect, respectively. The example in Figures 5A and 5B View FIGURE 5 shows slight sinuosity in the outer margin of the parameres, but this is not evident in all specimens. The parameres have very blunt, rounded tips and are slightly concave immediately round the tip along the inner margins. The surfaces of the parameres are covered in long, fine, forward pointing hairs. These hairs are located principally on the dorsal surface. At the tip of the parameres on the ventral surface, there are a few inward pointing hairs. The median lobe narrows steadily from the base to a blunt tip that falls short of the tips of the parameres. PL in the example shown in Figures 5A and 5B View FIGURE 5 is 356 µm. Figure 5C View FIGURE 5 shows an example of male A. festivus sternite IX. The posterior lobe is broad and parallel sided to an evenly rounded end with a small notch at the very tip. The entire length of the margin of the posterior lobe displays long, spikey setae, except across the notch which is bare. The setae at the posterior end are slightly shorter and more numerous with a few emerging from the surface of the lobe as well as the margin. One of the anterior pointing horns is slightly damaged. SL = 439 µm.
Figure 6 View FIGURE 6 shows A. festivus distribution. Anthrenus festivus is distributed around western Mediterranean only and is principally coastal. The countries shaded grey are those listed as containing A. festivus in the World Catalogue ( Háva 2023). Three countries: Germany, Switzerland, and Austria are hatched indicating dubious records resulting in their inclusion in the World Catalogue.
