Fig. 13. Genital skeletomusculature of Panorpa nuptialis (Mecoptera: Panorpidae). A, genitalia in situ, lateral. B, composite sclerite of tergum and sternum IX. CeE, genital appendages: C, dorsal; D, ventral; E, distal. FeH, right half of genital appendages: F, dorsolateral oblique; G, lateral, paired appendages of sperm pumping complex intact; H, lateral, left half of sperm pumping complex removed. I, J, mittelplatte and dorsal pseudoparameres (¼ kammersklerit plus second fragment of aedeagal apodem). K, pistilltrö ager, ventrolateral oblique.L, base of dorsal pseudoparameres, posterior view.M, base of dorsal pseudoparameres, internal (anterior) view. Abbreviations: Apd ¼ apodeme of pistilltrö ager; Ce ¼ cercus;d. ps. par. ¼ dorsal pseudoparamere; Cxa ¼ gonocoxa or first gonocoxites; Cxt ¼ gonocoxite; CxtAapd ¼ anterior apodeme of gonocoxite; CxtDapd ¼ dorsal apodeme of gonocoxite; mittelp. ¼ mittelplatte; pistillt. ¼ pistilltrö ager; Pen ¼ penis or penial sclerite; Prct ¼ proctiger; StIX ¼ sternum IX; Sty ¼ gonostylus; StyDcond ¼ dorsal stylar condyle; StyVcond ¼ ventral stylar condyle; TgIX ¼ tergum IX. Muscle abbreviations indicated in Table 1. Note: Sclerite fragment numbers indicated with Roman numerals; addition signs indicate sclerite fusion.
