The female genital structure of someBruchidius(Coleoptera, Bruchidae) species and their systematic importance

Evolution of Male and Female Genitalia Following Release From Sexual Selection

“…Comm.). Like the male genital spines (Rönn et al 2007), the female bursal spines exhibit considerable interspecific variation in form, size and number (Southgate 1971; Kingsolver 1979; Anton 2000; Mergen 2004).…”

“…In species where males have longer spines, females have evolved a thicker copulatory tract wall (Rönn et al 2007). Like many other bruchids (Southgate 1971; Kingsolver 1979; Anton 2000; Mergen 2004), C. maculatus females also possess blade‐like spines on the copulatory tract wall near the entrance to the bursa copulatrix (Southgate et al 1957). To our knowledge, the function of these female spines has never been investigated before.…”

Comparative morphology of the spermatheca in Megalopodidae (Coleoptera, Chrysomeloidea)1

“…The morphology of the SptCp and SptCd in Zeugophorinae and Megalopodinae is complex (Suzuki 1988, 2003), similar to that of Disteniidae where the SptC has a complex arrangement in the SptCd, the stem being globose, the SptCp being C–shaped, and the SptC being “?–shaped” (Lin and Murzin 2012, Bi and Lin 2013). In Chrysomelidae, Orsodacnidae and Cerambycidae the SptC is simple, C–shaped or hook–shaped, and the SptCd is wide (Suzuki 1988, Hernández 1993, Hernández and Ortuño 1992, Mergen 2004, Chamorro-Lacayo et al 2006, Yus-Ramos 2008, Gui-Yi and Li 2012). …”
