Abb. 6: Zeichnung des Genitalapparats des Ohrwurms Arixenia jacobsoni ♂, dorsal, koloriert; ein Hoden (blassblau) liegt dorsal, der andere ventral vom Penis (blassrot). Die dünnen Vasa deferentia (dunkelblau) münden dorsal vom Penis in die Samenblase (pink). Von dort läuft der Ductus ejaculatorius (D.e., rot) zur Basis des Penis. Kurz hinter der Samenblase zweigt das Rudiment eines zweiten D.e. ab (rot 3). Beim Eintritt in den Penis passiert der D.e. ein Vesikel mit kräftiger Muskulatur (rot 4). Nach einigen Windungen tritt der D.e. in einen sklerotisierten Abschnitt ein (rot 5). Dieser Abschnitt verbindet sich mit dem Eingang zum Präputialsack (gelb), der D.e. mündet jedoch (rot 2) in einen darunter liegenden 2. Hohlraum, vermutlich Rudiment eines zweiten Präputialsacks (ebenfalls gelb). Die Parameren (grün) sind gelenkig mit je einem Sklerit (schwarz 1) verbunden. Weitere Sklerite befinden sich am Präputialsack; Abbildung und Beschriftung nach Burr/Jordan[13]

Text Appearing Before Image: 414 closely applied to this curved base of the penis, the right one generally lying on top of the organ, more or less covering the space encircled by the crook, but sometimes being so far moved sideways as it is drawn in our figure. Each testicle (ts) contains sixteen follicles, which are rounded distally and narrowed towards the common duct. The follicles are pressed closely to- gether and form a compact body, the apical and dorsal sur- faces of which resem- ble to some extent a compound berry. In the structure of the testicle Arixenia essentially differs from Hemimerus and the Earwigs (as far as they have been ex- amined), the testis of these insects being composed of one or two follicles rolled up. The very slender vas deferens (vd) origin- ates at the ventral side of the testis and runs straight back- wards to near the Text Appearing After Image: par È4 B2 Figs. 24 and 25.—Reproductive organs oí A rixenia jacobsoni ^. ts, testis ; vd, vas deferens ; de, ductus ejaculatorius ; Vi, apex of same ; vs, vesicle ; dr, atrophied duct ; par, paramere ; le, lever of paramere (abbreviated) ; B^, B^, B^, B*, genital armature. rectum and then curves forward.^ 1 In Forfícula and a few other Earwigs dissected by me the vas deferens is also straight, not being coiled up as drawn by the earlier authors.—K.
