Ooceraea decamera

Identification
Ooceraea decamera and Ooceraea joshii are distinctly separated from the other valid congeners by having 10-segmented antennae. Furthermore, these two species are well distinguished from each other by a combination of the following characters
 * head shape (almost as long as broad in O. joshii, rectangular, distinctly longer than broad in O. decamera)
 * presence of ommatidia (present in O. joshii and absent in O. decamera)
 * propodeal lobes (reduced versus roundly produced)
 * petiolar node in lateral view (hemiglobular versus rectangular)
 * subpetiolar process (anteroventral part sickle-shaped versus forming a rectangular and semitransparent lobe)
 * pilosity (head and body comparatively more pilose in O. joshii)
 * sculpturation (head, mesosoma, petiolar, postpetiolar node, and gaster with more pronounced foveolate sculpture in O. joshii)

Distribution
Known only from the type locality. The place has been transformed into agricultural land and is prone to anthropogenic activities. Thus, this reinforces the concept that important biodiversity components, which are already rare, are imperiled due to local extinctions.
