description: Iden ti fica ti on key to the fi ft h-instar nymphs of some cicada species associated with co ff ee planta ti ons in Brazil
1. Femoral comb with seven or more teeth; length of anterior femur more than 5 mm long .............................. 2
1’. Femoral comb with less than seven teeth; length of anterior femur less than 5 mm long ................................. 3
2. Intermediate tooth of femur bifurcate (Fig 2g). Male 10th sternite with two soft globular protrusions in the anterior margin (Fig 3g) ............................. Quesada gigas
2’. With a single intermediate tooth on femur (Fig 2d). Male 10th sternite with two strong projections close to the anterior margin (Fig 3d) ............ Fidicina mannifera
3. Blade of tibia without any tooth; apex of the blade of tibia under-developed and separated from apical tooth by a light incision (Fig 2f). Male with posterior margin of 9th sternite with two protrusions and 10th sternite with strong ventral projection (Fig 3f) .................................... ..................................................................... Carineta fasciculata
3’. Blade of tibia with teeth; apex of the blade tibia developed and separated from the apical tooth of tibia by a strong incision .................................................................. 4
4. Tibia on mesothoracic legs with spines or protrusions along its length .......................................................................... 5
4’. Tibia on mesothoracic legs without spines or protrusions along its length. Wing cases shaded in the upper region (Fig 1a). Male 10th sternite with two globular protrusions in the anterior margin (Fig 3b) ........ ....................................................................... Dorisiana drewseni
5. Mid tibia with two short spines along its length, being the distance between these spines similar with the distance between the distal spine to the apex of tibia (Fig 5a). Male 10th sternite with two strong projections forming an open angle at the anterior margin (Fig 3c) ..... ............................................................................ Dorisiana viridis
5’. Mid tibia with about three protrusions along its length, being the distance between these protrusions less than the distance between the distal one to the apex of tibia (Fig 5c). Male 10th sternite pentagonal with two soft processes in the anterior margin (Fig 3e) .............................. ...................................................................... Fidicinoides pronoe
The assessment of the cicada infestation in coffee culture is based on number of nymphs in their roots (Souza et al 2007). With the use of the identification key to the fifth-instars nymphs of cicada will be possible be sure about the specie in any season of the year, in the detriment of the adults that are present in only few months of year (Martinelli & Zucchi 1997). This key may serve as a base to future researches about the ecology and biology of these species by association of the nymphs with the hosts.
