4.1.2 | Hybrids in Strombidae

The literature contains several references to strombid specimens possessing intermediate shell morphologies, interpreted as putative intrageneric (e.g., Dekkers, 2012b; Kronenberg, 2013; Liverani & Wieneke, 2016) and intergeneric hybrids, though none were tested with molecular data. While claims of intrageneric hybrids are plausible, intergeneric hybrids ( Latissistrombus latissimus × L. lambis , Conomurex decorus × Gibberulus gibberulus , L. latissimus × H. chiragra ; Dekkers & Maxwell, 2018; Kronenberg, 2008; Maxwell & Ocean, 2022) are less likely, as these occur between lineages separated for substantial periods, according to the chronogram: Latissistrombus × Lambis or Harpago , 71 Mya (95% HPD: 56–88 Mya); Conomurex × Gibberulus , 53 Mya (95% HPD: 38–69 Mya) (Figure 3). As far as we are aware, intergeneric hybrids are unknown in natural molluscan populations and appear in very few other groups (e.g., Franco-Trecu et al., 2016). Molecular data will be informative for understanding these taxa.
