Abstract
ABSTRACT The previously unknown female of Spodochlamys marahuaca Jameson & Ratcliffe, 2011 is described and illustrated for the first time based on two specimens collected in the region of the Juruá River, Amazonas state, Brazil. The specimens constitute a new record for Brazil. The identification key for species of Spodochlamys is updated, as well as the geographic distribution of the other two Brazilian species, S. caesarea Burmeister and S. iheringi Ohaus.

The ruteline beetles belonging to the Neotropical tribe Anatistini (Rutelinae) comprise 21 species distributed in four genera: Anatista Brême, 1844, Chalcochlamys Ohaus, 1905, Spinochlamys Machatschke, 1970 and Spodochlamys Burmeister, 1855, occuring from Honduras to central and western Brazil (Jameson and Ratcliffe 2011)
Jameson and Ratcliffe (2011) were correct when they hypothesized that the hitherto unknown female had dark, opaque elytra

Spodochlamys is the most diverse genus of Anatistini, with about 80% of the species, and can be distinguished from the other genera by the clypeal apex broadly rounded, parabolic, or with a median tooth, the pronotum not vertically elevated anteriorly, the mesoventrite not produced beyond the base of the mesocoxae, and the length of the antennal club subequal to twice the length of the antenommeres 2–7 combined (Jameson and Ratcliffe 2011).
