Type species.

Lumieria antonionii gen. et. sp. nov., by present designation.


Lumieria gen. nov. can be distinguished from all other Metasarcidae genera by the combination of following: Kappa-type DSS; area I divided; ocularium medially depressed, with two high tubercles, area III with two spines; posterior margin and free tergites with one or two higher tubercles; femur IV much longer than dorsal scutum length; penis VP and stylus robust and thick in lateral view; conspicuous dry-marks on the carapace, grooves of DS and free tergites.


Kappa-type DSS, with constriction I well marked and constriction II absent. Coda undefined, coalescing with mid-bulge. Ocularium low, medially depressed. Ocularium unarmed, small tuberculate or smooth. Areas of dorsal scutum small to moderately tuberculate. Area I divided in two halves. Area III armed with two high spines. Posterior margin armed with one or a pair of high tubercles. Coda short, without constriction. Coxa IV reaching area IV or posterior margin. Coxa IV unarmed (Figs 6A, B View Figure 6 , 24C, E View Figure 24 ). Femur IV much longer than dorsal scutum length (Figs 11C-F View Figure 11 , 24C, E View Figure 24 ). Less than 10 macrosetae C. Penis stylus elongate, robust, very thick and flattened latterally (with a almost subrectangular or claviform appearance in the lateral view), with apical or subapical projections. Penis VP thick in lateral view, with dorsal side with a robust curvature resulting in a laterally convex appearance (Figs 14A, B View Figure 14 , 17D-F View Figure 17 ).

Derivatio nominis.

The genus name, a noun in the nominative singular, is derived from Auguste Marie Louis Nicholas Lumière (1862-1954) and Louis Jean Lumière (1864-1948), the Lumière brothers, who were the inventors of cinematograph, being frequently referred like the parents of the “Cinema”. Gender feminine.
