Material examined

Attemsostreptus costatus Verhoeff, 1941 types (ZSM), 4 micro-preparations of 2 ♂♂ and 1 juvenile ♂.

TANZANIA • 1 ♂, juvenile, gonopods, 3 sections of a tergite; ZSM A20042783 • ♂ legs 1–7, gnathochilarium, labrum; ZSM A20042784 • ♂, gonopod in one block; ZSM A200427814 • 1 ♂, gonopods separated in left and right, left and right telopodites, two leg-pairs attached to a portion of sternite; ZSM A20042785.

Descriptive notes on gonopods

STERNUM (st). Small and simple, lower than paracoxite (px).

COXA. Proplica (pp) simple, straight and broad, distally with scattered bristles. Metaplica (mp) with a deep mesoapical incision, a rounded mesoapical metaplical process (map) and a long twisted and downturned lateroapical metaplical process (lap). The latter (lap) pointing proximolaterad and ending in claw-like pointed apex.

TELOPODITE. With a thin and curved antetorsal process (atp) ending in a pointed apex, post-torsal part forming a loop at mid-length, narrowing towards apex, apex bifurcate with a thin serrated lamella (sl) and an acuminate apical process.

Comments

Verhoeff (141: 263, pl. 12, fig. 36) described serrations on the margins of the ‘solenomere’ and three projections at the apex of the ‘telomere’. The descriptions and drawings of Krabbe (1982: 252 fig. 185) and Kraus (1985: 1–12, figs 30–34) match our observations.
