MORPHOMETRIC AFFINITY IN THE COCCINELLINI TRIBE (COLEOPTERA: COCCINELLIDAE) OF THE PERUVIAN COAST
Insects are important bioindicators of environmental quality; highlighting predators such as ladybugs (Coleoptera: Coccinellidae). The objective of this study was to use morphometry to differentiate species of the tribe Coccinellini (Coleoptera: Coccinellidae) from the central and southern Peruvian coast. For this, specimens were collected in the Lima and Ica Departments and identified in the laboratory. A total of 42 individuals were selected, measuring length and width of the body, pronotum and elytra; to develop a hierarchical cluster analysis, Ward's method and square Euclidean distance fixed in 8. According to the results, three groups of species were formed, the third being conformed only by Neda ostrina Mulsant, 1850. In conclusion, morphometry is useful to separate Coccinellini species groups.
