Base - special structuresSpecial structures at/ on embolus base absent (except for indistinct ridges or flat bulges that are often recognisable). Arising point6 o´clock-position. 7 o´clock-position. Direction of distalmost sectionprolatero-distally (with between 11° and 50° angle from longitudinal axis of cymbium). width relation - at arising point - subdistallyfrom 2.1x to 2.5x broader. width relation - subdistally - centrallyfrom > 1/2 to < 3/4 the width of central section. General structurewithout or with 1-3 (at most) longitudinal ridges. long. with less than 1/2 winding. with more than 1/2 winding but less than 3/4 winding. without distinct embolic lamella over entire embolus length. without apophysis. in ventral view subdistally not narrower or narrower, but not distinctly narrower than proximally (more than 1/7 as broad. narrow to medium-sized and hose shaped.

Colourationdark red-brown or brown with few lighter annulations, mainly at proximal articles and tarsi. completely or mainly with dark colour (e.g. dark red-brown) ((hardly with lighter sections, e.g. only tarsi lighter).
