(Afrius) purpureus</i> (e.g., Linnavuori 1989; Schouteden 1905a; Van Heerden 1931; Villiers 1952b) as well as for other pentatomids, such as <i>Nezara viridula</i> (Linnaeus, 1758) (e.g., Freeman 1940; Kiritani 1970; Ohno & Alam 1992; Vivan & Panizzi 2002; More <i>et al.</i> 2017) and <i>Stiretrus decemguttatus</i> (Lepeletier & Serville, 1828) (Paleari 2013) for colour pattern, and <i>Pinthaeus sanguinipes</i> (Fabricius, 1781) for variation in the pronotum, reported by Zhao <i>et al.</i> (2013). Besides, we could not find any connection between the polymorphism and the geographic distribution of <i>A.</i> (<i>Afrius</i>) <i>purpureus</i>, i.e., specimens that we have examined, despite different colour patterns and pronotum shapes, are sympatric. The localities where they were collected are denoted by the green dots on Fig. 1.</p><p>There has been considerable difference of opinion regarding the name used for this species, i.e., either <i>yolofa</i> /- <i>us</i>, <i>purpurea</i> /- <i>us</i> or <i>figurata</i> /- <i>us</i> and, sometimes, the latter used as a variety or subspecies of the second one (see review of the taxonomic history of the species above). Dallas (1851) was the first to synonymize <i>figuratus</i> and <i>yolofa</i>; he stated the date of publication of <i>Pentatoma yolofa</i> as 1830, while Stål (1864) stated it as 1829. Subsequent authors (including Stål 1870) accepted 1838 as the year of publication for <i>yolofa</i> and therefore they recognized either <i>figuratus</i> or <i>purpureus</i> as the valid name, Wallengren (1875) may have been the last author to use <i>yolofa</i> (misspelled as <i>Ylofa</i>) as a valid name while Larousse (1890) gave a brief description of it under the genus <i>Canthecona</i> (strangely, this entry first mentions that the type species of <i>Canthecona</i> is from Senegal and thereafter describes <i>C</i>. <i>yolofa</i>, as though implying it were the type species; the type species of <i>Canthecona</i> Amyot & Serville, 1843 is, however, <i>C</i>. <i>discolor</i> (Palisot de Beauvois, 1811), described from the Kingdom of Oware, now Southwest Nigeria). Dupuis (1952) demonstrated the priority of <i>Pentatoma yolofa</i> Guérin-Ménéville, 1831 over <i>Pentatoma purpurea</i> Westwood, 1837 and <i>Asopus figuratus</i> Germar, 1838. Thomas (1994) adopted the combination suggested by Dupuis (1952), <i>Afrius yolofus</i>. This was, as well, used by subsequent authors (Maldès & Pluot-Sigwalt 2004; Rebagliati <i>et al.</i> 2005; Kerisew 2011). Some others (Sileshi <i>et al.</i> 2001, 2004; Kerzhner <i>et al.</i> 2004; Rider 2006; Robertson 2009; Matesco <i>et al.</i> 2014), however, chose the combination <i>Afrius yolofa</i>, while others again still used <i>purpureus</i> and/or <i>figuratus</i> after 1952 (e.g., Mancini 1953; Villiers 1954, 1956; Leston 1954; Lindberg 1958; Schouteden 1963, 1964; Gillon 1972; Linnavuori 1975, 1976, 1982; Bourdouxhe & Jolivet 1981; Nuamah 1982; Matanmi & Hassan 1987; Balsbaugh 1988; Couilloud 1989; Quicke <i>et al.</i> 1992; Schaefer 1996; Tchibozo & Braet 2004; Poutouli <i>et al.</i> 2011; Agboton <i>et al.</i> 2014; Crétenet & Gourlot 2015) and yet others treated <i>figuratus</i> as a variety or a subspecies of <i>purpureus</i> (Schouteden 1905a, 1907a; Kirkaldy 1909; Schouteden 1909; Mancini 1937; Le Pelley 1959; Linnavuori 1989). Others still have used two or three combinations in the same work, possibly because they were reporting facts from primary sources, using the names as they were in the sources, and were not aware that the species were the same (Le Pelley 1959; Schaefer 1996).</p><p>The different combinations used for one and the same species clearly are the results of a few misconceptions: when and how <i>yolofa</i>, <i>figuratus</i> and <i>purpureus</i> were synonymized, the problematic dating of <i>yolofa</i> and <i>figuratus</i> and the status of <i>yolofa</i> as an adjective or a noun in apposition.</p> |

(Afrius) purpureus</i> (e.g., Linnavuori 1989; Schouteden 1905a; Van Heerden 1931; Villiers 1952b) as well as for other pentatomids, such as <i>Nezara viridula</i> (Linnaeus, 1758) (e.g., Freeman 1940; Kiritani 1970; Ohno & Alam 1992; Vivan & Panizzi 2002; More <i>et al.</i> 2017) and <i>Stiretrus decemguttatus</i> (Lepeletier & Serville, 1828) (Paleari 2013) for colour pattern, and <i>Pinthaeus sanguinipes</i> (Fabricius, 1781) for variation in the pronotum, reported by Zhao <i>et al.</i> (2013). Besides, we could not find any connection between the polymorphism and the geographic distribution of <i>A.</i> (<i>Afrius</i>) <i>purpureus</i>, i.e., specimens that we have examined, despite different colour patterns and pronotum shapes, are sympatric. The localities where they were collected are denoted by the green dots on Fig. 1.</p><p>There has been considerable difference of opinion regarding the name used for this species, i.e., either <i>yolofa</i> /- <i>us</i>, <i>purpurea</i> /- <i>us</i> or <i>figurata</i> /- <i>us</i> and, sometimes, the latter used as a variety or subspecies of the second one (see review of the taxonomic history of the species above). Dallas (1851) was the first to synonymize <i>figuratus</i> and <i>yolofa</i>; he stated the date of publication of <i>Pentatoma yolofa</i> as 1830, while Stål (1864) stated it as 1829. Subsequent authors (including Stål 1870) accepted 1838 as the year of publication for <i>yolofa</i> and therefore they recognized either <i>figuratus</i> or <i>purpureus</i> as the valid name, Wallengren (1875) may have been the last author to use <i>yolofa</i> (misspelled as <i>Ylofa</i>) as a valid name while Larousse (1890) gave a brief description of it under the genus <i>Canthecona</i> (strangely, this entry first mentions that the type species of <i>Canthecona</i> is from Senegal and thereafter describes <i>C</i>. <i>yolofa</i>, as though implying it were the type species; the type species of <i>Canthecona</i> Amyot & Serville, 1843 is, however, <i>C</i>. <i>discolor</i> (Palisot de Beauvois, 1811), described from the Kingdom of Oware, now Southwest Nigeria). Dupuis (1952) demonstrated the priority of <i>Pentatoma yolofa</i> Guérin-Ménéville, 1831 over <i>Pentatoma purpurea</i> Westwood, 1837 and <i>Asopus figuratus</i> Germar, 1838. Thomas (1994) adopted the combination suggested by Dupuis (1952), <i>Afrius yolofus</i>. This was, as well, used by subsequent authors (Maldès & Pluot-Sigwalt 2004; Rebagliati <i>et al.</i> 2005; Kerisew 2011). Some others (Sileshi <i>et al.</i> 2001, 2004; Kerzhner <i>et al.</i> 2004; Rider 2006; Robertson 2009; Matesco <i>et al.</i> 2014), however, chose the combination <i>Afrius yolofa</i>, while others again still used <i>purpureus</i> and/or <i>figuratus</i> after 1952 (e.g., Mancini 1953; Villiers 1954, 1956; Leston 1954; Lindberg 1958; Schouteden 1963, 1964; Gillon 1972; Linnavuori 1975, 1976, 1982; Bourdouxhe & Jolivet 1981; Nuamah 1982; Matanmi & Hassan 1987; Balsbaugh 1988; Couilloud 1989; Quicke <i>et al.</i> 1992; Schaefer 1996; Tchibozo & Braet 2004; Poutouli <i>et al.</i> 2011; Agboton <i>et al.</i> 2014; Crétenet & Gourlot 2015) and yet others treated <i>figuratus</i> as a variety or a subspecies of <i>purpureus</i> (Schouteden 1905a, 1907a; Kirkaldy 1909; Schouteden 1909; Mancini 1937; Le Pelley 1959; Linnavuori 1989). Others still have used two or three combinations in the same work, possibly because they were reporting facts from primary sources, using the names as they were in the sources, and were not aware that the species were the same (Le Pelley 1959; Schaefer 1996).</p><p>The different combinations used for one and the same species clearly are the results of a few misconceptions: when and how <i>yolofa</i>, <i>figuratus</i> and <i>purpureus</i> were synonymized, the problematic dating of <i>yolofa</i> and <i>figuratus</i> and the status of <i>yolofa</i> as an adjective or a noun in apposition.</p> |
