gonopod photos (those of the former are provided in supplemental information at http:// www.nature.com/nature/journal/v441/n7094/suppinfo/441707a.html), but a significant drawback to this practice is that details of the anterior gonopod sternum are not shown. Since gonopods represent modified legs that are joined by a sclerotized sternum, the structure is a fundamental part of the &quot;gonopod complex&quot; whose presence, absence, size, and configuration may hold taxonomic utility at generic and supra-generic levels. Just as gonopods can be modified, enlarged, and reduced, so can the sternum that connects them; it can even be vestigial or lost altogether, as in the tribes

Though tedious, dissecting and mounting the &quot;gonopod complex&quot; for SEM examinations seems advisable because the platform with the stub can be rotated to show details of the sternum and basal podomeres. Phylogenetically significant traits likely involve the sternum; omitting this structure from illustrations and ignoring its features could result in flawed taxonomies within the Colobognatha.
