  abstract = {{S}imple {S}ummary {S}everal members of the {C}imicidae family are ectoparasites of vertebrates. {S}ome of these are economically and medically important, e.g., the bed bugs, which are a global pest affecting humans. {T}he development of a method to easily identify species of the {C}imicidae family, despite the high morphological similarity of its members, will bring benefits such as the early detection of emerging infestations, facilitating the setup of adequate control and management measures. {O}ne of the existing methods, traditional morphometry (linear measurements and ratios of an object), is a demanding process involving the examination of many morphological features of well-preserved samples. {A}n alternative approach that uses only one morphological feature could be an asset. {T}herefore, we assessed the use of a single organ, the pronotum, to classify {C}imicidae via two methods: traditional and geometric morphometry (a method capturing the geometry of an object using coordinates as opposed to simple linear measurements and ratios). {B}oth methods were effective in classifying members of the family based on the pronotum; however, better quality data were obtained with geometric morphometry. {W}e recommend adopting the latter approach in future surveillance programs for medically important members and poultry pests of the family. {A}n infestation of a {C}imicidae ({H}emiptera: {C}imicidae) member, especially the bed bug, can cause economic loss and impact health. {A} cost-effective and user-friendly method for identifying the infesting species will help with the early detection and control of infestations. {A} linear morphometric method is often used, but it requires the examination of many characters and a highly preserved specimen. {W}e conducted a comparative morphometric study of the effectiveness of {C}imicidae classification using a single organ, the pronotum, through outline-based and linear morphometric methods. {B}at ({S}tricticimex parvus), human ({C}imex hemipterus), and bird ({P}aracimex sp.) ectoparasites were subject of the study. {W}ith both methods, the properties of size and shape were compared and used separately to classify the specimens. {C}lassification analyses of the two methods provided similar results, but more informative variables of size and shape were obtained with the outline-based approach. {S}ize, as analyzed with the outline-based method, could detect sexual dimorphism, and produced better reclassification. {T}he shape variables obtained from the linear measurements were strongly influenced by size variation, much more than the ones obtained from coordinates describing the pronotum contours. {O}ur data suggest that the outline-based approach provides better characterization variables, thus we recommend them for a wider use in other {C}imicidae family members.},
