DNA barcode

CO1 sequences (652‒659bp) were obtained of two specimens detailed below and allocated to two BINs, BOLD:AEP5411 (ZSM-DIP-42303-G10) and BOLD:AEP5413 (ZSM-DIP-42303-E02). The fact that the two genetic clusters, labeled here A and B, are supported by morphological differences, suggests the presence of two discrete species. In A, the tegmen is strictly parallel-sided (↓ 1, Fig. 19A View Fig ) and sharply pointed apically (↓ 2); in B, it is slightly constricted near the midlength (↓ 1, Fig. 19B View Fig ) and narrowly rounded apically (↓ 2). Also, the gonocoxal ventral emargination of A might be broader and U- rather than V-shaped compared with B (↓ 3, Fig. 19A‒B View Fig ), and the undulating sclerotized rim at the inside of the gonocoxal wall is entirely sharply demarcated in A, while it is seemingly interrupted in B (↓ 4, Fig. 19A‒B View Fig ). Both characters, outline of the emargination and appearance of the rim, might be interdependent. Since possible effects of individual variation and preparation artefacts cannot be assessed in the absence of further specimens for study, I refrain here from naming the potential sibling species. Also, it remains to be settled through study of the holotype which of the clusters is the genuine D. quadridens . Search on BOLD’s BIN Database retrieved no further results for these BINs (accessed 27 Aug. 2023).
