INTRODUCTION
LENCIONI (2004) listed nine species of Telagrion, seven from Brazil, when
he described T. nathaliae.Thenewspecies describedherein brings thetotal de-
scribedspecies to 10. Thelarva isunknownas withall speciesof Telagrion. The
genus Telagrion isrecordedfromBoliviaforthefirst time.

DIAGNOSIS
Theflavescent/brownish wings willimmediately separate Telagrion boliviensis
malesandfemalesfromallknown Telagrion species as they havehyaline wings.

Telebasisboliviensiscommonly inhabitslakes ingrassland andopenpastures
thatare mostly surroundedby marginal forest. Immatureadults remain in the
forestunderbrushduring the dryseason. Thedarkermature adultsreturn to the
lakes at theadventofthe rainy seasonto breed.Odonatespecies collectedwith
T. boliviensisincludeTelebasisgigantea Daigle, and Lestesjurzitzai Muzon. At
leastone ofthree specimens that havebeentaken atthe Tambopata Reserve in
Peruwas inthe middleof primary forest, along way fromany openarea. They
werecollectedthere only during the rainyseason, andnonewas foundduring a
month-longvisit inthe dryseason(D. R. Paulson, pers.comm.).
