Key for species identification using exuviae Species may be differentiated by the morphology of their exuviae (see Figs. 1, 4-10). Females of M. aper and F. mannifera present dubious characteristics and are not easy to distinguish them. 1. Large or medium size, length 2.6 cm .............................. 2 1’. Length 2,6 cm ................................................................. 5 2. Light beige coloration ........................................................ 3 2’. Dark beige/brown coloration ............................................ 4 3. Light beige with white patches, male> 3.7 cm, female> 3.3 cm .................................................................. Quesada gigas 3’. Normal beige with or without white patches; medium size, male: 3.1-3.8 cm, female: 3.0-3.4 cm; male developing genitalia longer than wider and without anterior barbs; profemoral intermediary tooth single or slightly undulated ....................................................... Fidicinoides determinata 4. Medium large (male: 3-3.7 cm; female: 2.9-3.5 cm), light gray sternites, generally with soil attached, male developing genitalia with two light protuberances ..... Majeorona aper 4’. Medium small (male: 2.7-3.3 cm; female: 2.5-3.3 cm), more intense coloration, more “glossy”, dark gray sternites; male developing genitalia with two proximate barbs; profemur darker coloration ................................... Fidicina mannifera 5. Length: 2.2-2.6 cm, light beige, white patches can be present, normal setae ........................................... Fidicinoides pronoe 5’. Not as above ....................................................................... 6 6. Length: 1.8-2.4 cm, whitish beige coloration, pilous body, larger and more abundant setae ................... Dorisiana sp. 6’. Normal light beige coloration, normal setae ................... 7 7. Small (male: 1.6-2.1 cm), male developing genitalia with two barbs ................................................... Dorisiana viridis 7’.
