Hi Bill,
Concerning the current discussion on the Forum about Siphopteron quadrispinosum. After comparing the description of S. leah with that of S. quadrispinosum, there is little question in my mind that they are the same species. The external coloration, radular teeth, form of the penis (with deeply separated prostatic and penial ducts and a penis with few large spines) are unique to these species. The discrepancies noted by Klussman-Kolb and Klussmann, seem relatively minor. It could be that the two spines versus four may represent individual variation or it may be that they did not see the other two spines. Given that they didn't describe the other details of the penial morphology (such as the papilla with smaller spines and the penial papilla with a reticulate spine) it is difficult to be absolutely certain, but they sure look the same.
