Fig.16. Genital skeletomusculature of Pycnopsyche antica (Trichoptera: Limnephilidae).A, genital and pregenital segments, lateral.B, genital and postgenital segments, posterior.C, same as B, left coxopod removed. D, same as C, lateral oblique. E, genital and postgenital segments, ventral. F, genital appendages, dorsolateral oblique. G, same as F, left gonopod removed. H, right gonopod and piece of postgenital complex, muscles removed, mesal (medial). IeK, penial sclerite and lateropenites: I, dorsolateral; J, dorsolateral, sheath membrane removed; K, ventrolateral, base of penial sclerite torn open. Abbreviations:?Ce ¼ structures possibly homologous with cerci; Cxa ¼ gonocoxa; Lpe ¼ lateropenite; Pen ¼ penis or penial sclerite; Prct ¼ proctiger; Seg ¼ segment; St ¼ sternum; Sty ¼ gonostylus; Tg ¼ tergum.Muscle abbreviations indicated in Table 1. Note: Segment numbers indicated with Roman numerals; addition signs indicate sclerite fusion.
