Metaterga 2-19 each with 2+2 and 2+2 (or 2+3) coniform spines arranged in two transverse rows, lateral spines of posterior rows much larger than the others in metaterga 2-18 (Figs 7

Paraterga 2-8 directed obliquely upwards at ca 45°, following pareterga growing increasingly horizontal and ending up clearly above dorsum in ♂ (Fig. 7
