FIGURE 11 in Structure and phylogenetic significance of the sternum V glands in Trichoptera 2884
FIGURE 11. 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: Agraylea multipunctata (Hydroptilidae) female, male very similar. B: Palaeagaptus guppyi (Hydroptilidae) male, female very similar. The secretory tissue was not discernible, possibly due to decomposition. Go, gland opening; Ip, insertion point for muscle; Op, origin point for muscle; Rs, gland reservoir; Sc, secretory cells; L-t, Lepidoptera-type opening muscle.
FIGURE 9 in Structure and phylogenetic significance of the sternum V glands in Trichoptera 2884
FIGURE 9. 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–D: Hydrobiosidae. A: Apsilochorema segitiga female, note the sharp bend in the gland duct. The secretory tissue was not discernible, possibly due to decomposition. B: Cailloma pumida female, note the sharp bend in the gland duct. The gland opening muscle was missing, most likely due to decomposition. C and D: Atopsyche callosa male and female, respectively. Note the sharp bend in the gland duct in the female. E and F: Rhyacophila arnaudi (Rhyacophilidae) female and male, respectively. Note that the Lepidoptera-type opening muscle originates medioanterially on sternum VI and inserts on the gland duct wall just inside gland opening. The secretory tissue in the male was not discernible, possibly due to decomposition. S V, sternum V; S VI, sternum VI; 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; L-t, Lepidopteratype opening muscle.
FIGURE 4 in Tadpole buccal secretory glands as new support for a Neotropical clade of frogs
FIGURE 4. Optimization of nine characters (see main text) relevant to the understanding of relationship and evolution among major Leptodactylus groups in two competing hypotheses. A) One of the most parsimonious reconstructions (Acctran) on the scenario of Ponssa (2008) (16 steps; CI = 56; RI = 22). B) a different topology emphasizing a preferential relationship among species of the L. fuscus and L. marmoratus groups, as suggested by Kokubum & Giaretta (2005) (11 steps; CI = 82; RI = 78).
