Family Pilumnoididae The male gonopore is coxal. The penis emerges from the large gonopore situated on the P5 coxo-sternal condyle in close proximity to the distal extremity of the condyle, more precisely on its anterior margin; the thick and recurved remaining condylar portion articulates on sternite 8 (Guinot 1979a: fig. 21A; Guinot & Macpherson 1987: fig. 1) (see Modalities of penis protection: Condylar protection). The precise relationships of the family remain unknown (Guinot & Macpherson 1987), with, however, larval results suggesting affinities with Carpiliidae (Luppi et al. 2010).
