  abstract = {{M}odern methods allow a geometric representation of forms, separating size and shape. {I}n entomology, as well as in many other fields involving arthropod studies, shape variation has proved useful for species identification and population characterization. {I}n medical entomology, it has been applied to very specific questions such as population structure, reinfestation of insecticide-treated areas and cryptic species recognition. {F}or shape comparisons, great importance is given to the quality of landmarks in terms of comparability. {T}wo conceptually and statistically separate approaches are: (i) landmark-based morphometrics, based on the relative position of a few anatomical "true' or "traditional' landmarks, and (ii) outline-based morphometrics, which captures the contour of forms through a sequence of close "pseudo-landmarks'. {M}ost of the studies on insects of medical, veterinary or economic importance make use of the landmark approach. {T}he present survey makes a case for the outline method, here based on elliptic {F}ourier analysis. {T}he collection of pseudo-landmarks may require the manual digitization of many points and, for this reason, might appear less attractive. {I}t, however, has the ability to compare homologous organs or structures having no landmarks at all. {T}his strength offers the possibility to study a wider range of anatomical structures and thus, a larger range of arthropods. {W}e present a few examples highlighting its interest for separating close or cryptic species, or characterizing conspecific geographic populations, in a series of different vector organisms. {I}n this simple application, i.e. the recognition of close or cryptic forms, the outline approach provided similar scores as those obtained by the landmark-based approach.},
