FIGURE 14 in Structure and phylogenetic significance of the sternum V glands in Trichoptera 2884

FIGURE 14. Drawings based on wholemounts. The structures are viewed through the cuticle and anterior is to the left with down being mesal; thus all drawings show the left gland. Muscle fibres are grey and all structures are drawn as if they were transparent. Transparency of cuticle is not indicated. A–F: Limnephilidae sensu lato, note the complete absence of gland reservoir musculature. A and B: Neophylax concinnus (Uenoidae) female and male, respectively. Female has very typical reniform gland. C–F: Limnephilidae. C: Onocosmoecus unicolor (Dicosmoecinae) female, male similar. D: Drusus annulatus (Drusinae) male, aberrant reniform gland with gland duct at one end. Female has normal reniform gland. E: Pseudostenophylax sparsus (Pseudostenophylacinae) female, male similar. F: Limnephilus secludens (Limnephilinae) female, male similar. Female L. sericeus similar. Go, gland opening; Ip, insertion point for muscle; Op, origin point for muscle; Rs, gland reservoir; Sc, secretory cells; T-t, Trichoptera-type opening muscle.
