Fig.12. Genital skeletomusculature of Apterobittacus apterus (Mecoptera:Bittacidae).AeC, genital and pregenital segments: A, lateral; B, distal; C, ventral.DeG, genital appendages and sternum IX: D, dorsal; E, lateral (partially dissected); F, lateral, left fragment of first coxite removed; G, same as F, with more muscle removed. H, left fragment of first coxite, mesal. IeN, complex of second coxite, lateropenite, and penial sclerite: I, lateral, first penial sclerite fragment removed; J, dorsal; K, dorsal, first penial sclerite fragment removed, dorsal.L, second coxites and first penial sclerite fragment removed,dorsal. M, same as L, dorsolateral oblique. N, first penial fragment,ventral (mesal), left and median tines partially broken. Abbreviations: Apd ¼ apodeme; Ce ¼ cercus; Cxa ¼ gonocoxa or first gonocoxites; Cxt# ¼ gonocoxite fragment; Lpe ¼ lateropenite; Pen# ¼ penial sclerite fragment; Prct ¼ proctiger; Sclbr-b-a'' ¼ sclerotic bridge between mittelplatte and second fragment of aedeagal apodem; Sclbr-cxt-cxt ¼ sclerotic bridge between first gonocoxites; SegVII ¼ seventh abdominal segment; Seg VIII ¼ abdominal segment VIII; StIX ¼ sternum IX; Sty ¼ stylus; TgIX ¼ tergum IX. Muscle abbreviations indicated in Table 1. Note: Sclerite fragment numbers indicated with Roman numerals; addition signs indicate sclerite fusion.
