Handwritten label to left of cover slip: ‘14077: Asp. /Targionia/riverae Ckll. /Chusquea sp. /Fam. Gramineas [sic] /Prov. Arauco (Chile?) /Schrottlsy?/Oct. 1904/ No 22. /Type’ (USNM).

Remarks

• Systematics: DNA sequence fragments of several loci of Chusqueaspis riverae have been submitted to Genbank: 28S, accession number MT790770 (PA835A); COI, accession numbers MT790345 (PA835A) and MT790346 (PA835A). Chusqueaspis riverae is easily distinguished from the other species of Chusqueaspis by the presence of perivulvar pores (perivulvar pores absent in both C. patriciae and C. gonzalezi).
• Structure: Female scale about 3 mm long, oval, moderately convex, rough, grayish brown, with the large uncovered ochreous exuviae near one end (Cockerell, 1905d). Dorsal scale cover of female convex, subcircular initially, becoming oval at full maturity, exuviae submarginal, yellow to orange; ventral cover thick; body colour dark pink. Oviparous, eggs light pink 0.29 × 0.13mm(n = 3); adult females with eggs observed in October in the RN Nonguén; crawlers beige to pink‐beige. (Amouroux, et al., 2020) Slide‐mounted adult female. Not pupillarial; 0.8–2.2 (median 1.8) mm long, 0.7–1.6 (median 1.3) mm wide. Body outline turbinate, broadest at mesothorax. Derm membranous or slightly sclerotised. (Amouroux, et al., 2020)
• Biology: The presence of adult females with eggs at the beginning of the springtime (October) suggests that the female overwinters as a second‐instar nymph, or as an adult. (Amouroux, et al., 2020)
• General Remarks: Description of adult female by Cockerell (1905d). Ddetailed redescription, illustration and photographs in Amouroux, et al., 2020.
