- Description: Reinvestigation of mitochondrial haplotypes previously reported to be shared between the Afrotropical blowflies Chrysomya putoria Weidemann and Chrysomya chloropyga Weidemann (Diptera: Calliphoridae) revealed an error resulting from the misidentification of specimens. Preliminary amplified fragment length polymorphism (AFLP) analysis of the original and additional individuals again failed to find reciprocal monophyly, leading to a re‐examination of the specimens for diagnostic male genitalic characters that were first described following the earlier study. Four of the original study specimens were found to have been misidentified, and definitive analysis of both mtDNA and AFLP genotypes using phylogenetic analysis and genetic assignment showed that each species was indeed reciprocally monophyletic. In addition to correcting the earlier error, this study illustrates how AFLP analysis can be used for efficient and effective specimen identification through both phylogenetic analysis and genetic assignment, and suggests that the latter method has special advantages for identification when no conspecific specimens are represented in the reference database.

- Description: Preservation of viable tissue is important in wound management. It is achieved by small, incremental removal of devitalised, necrotic and infected tissues. Maggot debridement therapy (MDT) is used in septic necrotic wounds that fail to respond to conventional modalities. MDT has relied on Lucilia cuprina, which consumes only necrotic tissues, as opposed to Lucilia cuprina, which devours both flesh and necrotic tissues. Recent findings have shown that L. cuprina consumes mainly necrotic and very small amounts of viable tissues and may be used in MDT where L. sericata is very rare or absent. Here we describe wound healing in a patient from rural South Africa with cutaneous myiasis. Our findings agree with workers who indicated that L. cuprina could be used in MDT.
