Also, in our descriptions, unless stated otherwise, all setae, other than the submedian setae, are smooth and pointed (not thorny, hooked or blunt).shared Generic Characteristics The chrysopid life cycle includes a larval stage with three instars. The first instar differs markedly in structure, setation and often coloration from the other two instars, which differ from each other only in minor ways, largely related to size. Thus, for taxonomic purposes, the first instar constitutes Semaphoront A, whereas Semaphoront B includes both the second and third instars and Semaphoront C encompasses all instars (= the larva) (See Wheeler 1990). We use the term “semaphoront” in our descriptions because of its systematic and phylogenetic value. Specifically: (i) the term highlights the relative degree of morphological CBR-5884 supplier change that occurs with each instar during NVP-BEZ235MedChemExpress NVP-BEZ235 metamorphosis, (ii) it reflects accurately the relative value of the three chrysopid instars to phylogenetic analysis, and (iii) the commonality of the pattern of variation among semaphoronts across chrysopid taxa, and indeed taxa in other insect orders (see Wheeler 1990), itself is of considerable biological interest. Chrysopid genera fall into two general categories: those with “naked” larvae and those with “trash-carrying” larvae. Chrysopodes larvae are typical examples of the lat-Patr ia S. Silva et al. / ZooKeys 262: 39?2 (2013)ter ?that is, they have compact, globose bodies, hooked abdominal setae, and well developed thoracic and abdominal tubercles that bear elongate setae adapted for carrying small pieces of plant or animal debris. Furthermore, Chrysopodes larvae express a unique set of morphological and setal characters that distinguishes them from the larvae of other trash-carrying genera (Tauber 2003; for additional comparisons, see D zAranda and Monserrat 1995, Tsukaguchi 1995, Monserrat and D z-Aranda 2012). In general, the species studied here exhibit all of the larval characteristics proposed earlier to typify Chrysopodes (Tauber 2003); moreover, several additional characteristic features were discovered during the current study. Thus, we provide an up-dated list of shared Chrysopodes generic-level characteristics (Appendix); those that are new as a result of the current study are marked with an asterisk. Among the most distinctive features that were previously unreported are the uniquely shaped submedian setae (SMS) on the anterior abdominal segments of all instars (Fig. 1C). These long, smooth, hooked setae are slender and bent throughout the midregion, but their hooked tips are robust, rigid and laterally compressed.
