The specific epithet, chusqueae is the genitive singular of the generic name of the aphid's host plant.	en	Hidalgo, Nicolas Perez, Martinez-Torres, David, Collantes-Alegre, Jorge Mariano, Muller, William Villalobos, Nafria, Juan M.

A0EF33E82F9734F49A44292FD82E3E89.taxon	distribution	Distribution and host-plant. Chusquea tomentosa (Poaceae, Bambusoideae) is the only known host of Rhopalosiphum chusqueae. This bamboo is endemic to the country and can be found in several areas of the Cordillera de Talamanca at an altitude of between 2450 and 3000 m (Widmer 1997; Hammel et al. 2003). Species of Chusquea (approximately 120 described) can be found at between 800 and 3800 m in dry and humid forests from Mexico to Chile and Argentina (Clark 1989). As species in the genus Rhopalosiphum are not strictly stenophagous, Rhopalosiphum chusqueae may also live on other species of Chusquea, or even on other bamboos and live in other parts of America. On the plant, the aphids live close to the nodes well protected by the leaves (Figs 1 C, 1 D) and not easily detectable, as shown by fruitless efforts to locate other colonies. So far, only one aphid species had been recorded on Chusquea: Hysteroneura setariae (Thomas) on Chusquea abietifolia Griseb, in Cuba (Holman 1974). Blackman and Eastop (1994) present two identification keys to the aphid species living on Arundinaria and on Bambusa, genera that include arboreal bamboos; several of these aphid species belong to the subfamily Aphidinae. Blackman and Eastop (2006) report the presence of aphid species on several genera of non-arboreal bamboos such as Chusquea, Pseudosasa, Sinoarundinaria, Thamnocalamus, Thysanolaena, and also Arundinaria (other bamboo genera are included but no Aphidinae species have been recorded on them), and for the identification of these species the reader is forwarded to the " keys [of 1994] to aphids on Arundinaria and Bambusa ", or to the " keys [of 2006] to apterae on Digitaria and other genera of herbaceous Poaceae ". To make the identification work easier, it seems useful to present one compendium-key to the identification of apterous viviparous females of Aphidinae species recorded on species of Bambusoideae in the World. This key has been prepared using the general structure and several couplets in all of those keys by Blackman and Eastop; thirteen Aphidinae species and subspecies have been included, and are: Hysteroneura setariae (Thomas, 1878), Melanaphis arundinariae (Takahashi, 1937), Melanaphis bambusae (Fullaway, 1910), Melanaphis meghalayensis bengalensis Raychaudhuri [D. N.] and Banerjee [C.], 1974, Melanaphis meghalayensis meghalayensis Raychaudhuri [D. N.] and Banerjee [C.], 1974, Melanaphis pahanensis (Takahashi, 1950), Melanaphis sacchari (Zehntner, 1897), Rhopalosiphum arundinariae (Tissot, 1933) and Rhopalosiphum rufiabdominale (Schrank, 1899) (Aphidinae Aphidini Rhopalosiphina), and Sitobion bambusicola (Ghosh [L. K.], 1986), Sitobion fragariae (Walker, 1848), Sitobion miscanthi (Takahashi, 1921) and Sitobion papillatum subnudum Remaudiere, 1985 (Aphidinae Macrosiphini).	en	Hidalgo, Nicolas Perez, Martinez-Torres, David, Collantes-Alegre, Jorge Mariano, Muller, William Villalobos, Nafria, Juan M.
