Fore femur with three strongly developed posterodorsal setae, median seta being considerably stronger than supramedian and posteromedian
setae; three preapical dorsal setae, two median dorsal setae, 10 posteroventral setae evenly spaced on femur, no differentiated posterior setae.
Surface of mesoscutum distinctly shagreened peripherally, smooth and polished posteromedially; punctatorugose except the small shiny posteromedian
area, here punctures separated by 1 to 2 puncture diameters.
Anteromedian sulcus moderately deep, ovate; posteromedian
sulcus narrow, shallow anteriorly, deep posteriorly; posterolateral sulci shallow, wide, curved; posteromarginal sulcus deep, narrow.
8O): Median notch less deep with seven pairs of plumose setae and one posteromedian spine.
9J): Posterior margin straight, with seven pairs of plumose setae and one posteromedian spine.
The anterior, lateral and posterior margins of syntergite I-III, the fusion lines between mediotergites I-II and II-III, the posterior and lateral margins of mediotergites IV-VI, the lateral margins of mediotergite VII, the posteromedian
angles of epipleurites II-VI, and the posterior margins of all visible abdominal sternites are conspicuously elevated, and ornamented with setigerous tubercles.
89 times longer than pronotum and vertex combined; 3 longitudinal carinae all reaching anterior and posterior margins, median carina indistinct on posteromedian
area, which bears transverse striations.
Carapace: three pairs of lateral ocelli; ocular tubercle prominent, median ocelli separated by one diameter; anterior margin with weak median notch, anterior median and anterior marginal furrows only weakly developed; median ocular furrow present, lateral ocular furrows weak, median and posteromedian
furrows strong, with a depressed area in between, posterior transverse furrows absent, posterolateral furrows well developed.
Legs: Profemur without anteroventral ctenidium; posteriorly with strong posterodorsal, weak posteromedian
and strong posteroventral setal rows.
