Rhynchasphaera basisticta Bechyné, 1958

( Figure 7 )

Rhynchasphaera basisticta Bechyné 1958:680 ( Peru: Oxapampa , holotype female).

Measurements. LB = 8.58 mm; WB = 4.91 mm (N=1)

Distribution. Peru.

Type examined. Holotype female: Oxapampa Peru, Type Rhynchasphaera basisticta ns. J. Bechyne det., 1957 ( NMB).

Literature records. PERU: Oxapampa (Mus. G. Frey) ( Bechyné 1958).

Description of genitalia. Dissection of the holotype was not possible due to the poor condition of the abdomen.

Diagnosis. Rhynchasphaera basisticta can quite easily be separated from the two other species in this genus, based on the elytral coloration alone (see key above, Figure 7 ). Rhynchasphaera basisticta can additionally be separated from R. latipleura by having shiny (less deeply punctate) elytra ( Figure 7A ), and elytra that are not evenly rounded when viewed laterally (in R. basisticta , the basal half of the elytra is much less rounded than the apical half, Figure 7B ). Rhynchasphaera basisticta can be further separated from R. orophila by having a clearly punctate frons ( Figure 7C ).
