“…As might then be expected from the resulting interlocus sexual conflicts, love darts are highly variable across species (Koene and Schulenburg 2005;Koene et al 2013) and display signatures of antagonistic coevolution and counteradaptation by sperm recipients in the form of modified reproductive organ morphologies (Koene and Schulenburg 2005; see also Davison et al 2005;Beese et al 2009;Sauer and Hausdorf 2009). Similar functions may be performed by the copulatory setae of earthworms (Koene et al 2002König et al 2006) and devices such as the stylet-like penis appendage found in Siphopteron sea slugs Lange et al 2014) and the penial gland that is everted following external sperm exchange in Deroceras land slugs (Reise 2007;Reise et al 2007;Benke et al 2010; for a recent review of "traumatic secretion transfer," see also Beese et al 2009 andLange et al 2013a). In all of these cases, however, the exact costs and benefits to donor and recipient because of either wounding or receipt of a specific (manipulative) substance under naturalistic conditions remain to be determined.…”

Hermaphrodites combine the male and female sex functions into a single individual, either sequentially or simultaneously. This simple fact means that they exhibit both similarities and differences in the way in which they experience, and respond to, sexual conflict compared to separate-sexed organisms. Here, we focus on clarifying how sexual conflict concepts can be adapted to apply to all anisogamous sexual systems and review unique (or especially important) aspects of sexual conflict in hermaphroditic animals. These include conflicts over the timing of sex change in sequential hermaphrodites, and in simultaneous hermaphrodites, over both sex roles and the postmating manipulation of the sperm recipient by the sperm donor. Extending and applying sexual conflict thinking to hermaphrodites can identify general evolutionary principles and help explain some of the unique reproductive diversity found among animals exhibiting this widespread but to date understudied sexual system.

The name Deroceras panormitanum is generally applied to a terrestrial slug that has spread worldwide and can be a pest; earlier this tramp species had been called Deroceras caruanae. Neither name is appropriate. The taxonomic descriptions apply to a species from Sicily and Malta. This true D. panormitanum and the tramp species are distinct in morphology and mating behaviour. For instance, the penial caecum of D. panormitanum is more pointed, everting faster at copulation. The size of the penial lobe varies considerably in preserved specimens but is always prominent at copulation. D. panormitanum is distinct from the Maltese endemic Deroceras golcheri, but a phylogeny based on mtDNA COI sequences implies that they are more closely related than is the tramp species. D. golcheri has a still closer counterpart on Sicily, but we leave the taxonomy of this "species X" unresolved. In interspecific crosses, D. panormitanum may transfer sperm to the partner's sarcobelum whereas the partner fails to evert its penis (D. golcheri) or to transfer sperm (the tramp species). Names previously applied to the tramp species originally referred to D. panormitanum or are otherwise invalid, so it is here formally redescribed as D. invadens. Deroceras giustianum Wiktor, 1998 is synonymised with D. panormitanum.

“…Asami et al (1998) verified the prediction that chiral speciation has been more frequent in tall-shelled groups, in which the interchiral mating barrier is less strong. Reciprocal mating in slugs (South, 1992;Reise et al, 2002;Reise, 2007) also explains their lack of mirror-image species in the relatively small number of slug taxa compared to reciprocally mating snail taxa.…”

The unique nature of body handedness, which is distinct from the anteroposterior and dorsoventral polarities, has been attracting growing interest in diverse biological disciplines. Recent research progress on the left-right asymmetry of animal development has focused new attention on the mechanisms underlying the development and evolution of invertebrate handedness. This exploratory review of currently available information illuminates the prospective value of Drosophila and pulmonate snails for innovative new research aimed at elucidating these mechanisms. For example, findings in Drosophila and snails suggest that an actin filament-dependent mechanism may be evolutionarily conserved in protostomes. The polarity conservation of primary asymmetry across most metazoan phyla, which visceral handedness represents, indicates developmental constraint and purifying selection as possible but unexplored mechanisms. Comparative studies using Drosophila and snails, which have the great advantages of using genetic and evolutionary approaches, will accelerate our understanding of the mechanisms governing the conservation and diversity of animal handedness.
