Lateral margin regularly convex from base up to just below level of <i>prl</i>, at this place turning slightly laterad and forming blunt, rounded angle with oblique apical margin; cucullus (<i>cu</i>) hence subtriangular, apically rounded. Metaplical flange (<i>mf</i>) ending in long, triangular process pointing anteriad-mesad-distad; metaplical mesal margin straight up to level of arculus. Metaplical shelf (<i>ms</i>) forming subrectangular-rounded process just distal to arculus, followed by triangular incision separating cucullus from basal part of metaplica. <i>ms</i> simple, proximally stout, continuing in metaplical shelf-spine (<i>mss</i>) with no clear demarcation. <i>mss</i> medium long, originating from anterior-distal surface of <i>ms</i>, first projecting distad, then curving mesad, and then slightly basad.</p><p>GONOPOD TELOPODITE (Figs 8A, 27).

Telomere distally with two branches:</p><p>• a large anterior lamella dividing into two triangular lobes (<i>al1</i> and <i>al2</i>) with strongly laciniate margins; basalmost lobe (<i>al2</i>) folded laterad and <i>in situ</i> visible in front of opposite coxa,</p><p>• a large posterior lamella (<i>pl</i>) first directed distad then folding back and delimiting an empty space together with <i>al2</i>.</p><p><b>Distribution and habitat</b></p><p>Known only from Udzungwa Mts, New Dabaga/Ulangambi FR.
