Type material (examined): Holotype: SOUTH AFRICA: Eastern Cape: 1ơ, Mt. Ayliff [3029CD], on road, xi.1961, R. F. Lawrence ( NMSA 8209 About NMSA ) . Paratype: 1ơ, same data as holotype .
Etymology: This species is named for Prof. Robert Slotow (University of Natal), in recognition of his interest in millipede biogeography, and his contribution of numerous specimens for this study.
Diagnosis: Telopodite with one long, narrow, apically tapered and slightly curved femoral spine partially concealed under posterior telocoxal fold ( Figs 176, 179, 180 View Figs 175–183 ). Distally, medial margin of anterior telocoxal fold extended to form a large, aborally directed, flattened process with two to four teeth/telocoxal spines apically (spine plate) ( Figs 176, 177, 179 View Figs 175–183 ).
Description:
Dimensions: Males, n = 3. Body width 6.0, 6.0–7.5; collum width 6.3, 6.0–7.5; body length 70.0, 65.0–75.0; leg length 4.0, 4.0–4.7; antenna length 5.0, 5.0–5.0.
Number of segments: 43, 43–45.
Colour: Head, clypeus, and collum brown. Prozonites and mesozonites orange, metazonites brown. Pre-anal ring and anal valve orange. Tip of caudal spine dark brown. Legs and antennae brown.
First ozopore: Segment 5.
Collum: One submarginal groove, anterior corner rounded, forming an angle of about 90˚ ( Fig. 182 View Figs 175–183 ).
Gonopods: One long, narrow and slightly curved femoral spine emerging from flexure of telopodite ( Fig. 180 View Figs 175–183 ), this partially concealed under posterior telocoxal fold ( Figs 176, 179 View Figs 175–183 ). Pectinophore curved towards thumb. Thumb a concave/saucer-like laminate plate widening apically, dentate along distal margin and curved towards pectinophore. Second lamella distally widened ( Figs 178, 181 View Figs 175–183 ). Distally, medial margin of anterior telocoxal fold extended to form a spine plate, a prominent, aborally directed, flattened, broad, plate-like protrusion with two to four teeth/telocoxal spines apically, positioned one above the other ( Figs 177, 179 View Figs 175–183 ). Anterior margin of posterior telocoxal fold sloping diagonally, not concealing telocoxal spines nor overlapping opposite posterior telocoxal fold ( Figs 175, 176 View Figs 175–183 ). Lateral margin of posterior telocoxal fold without distinct projection. Pre-anal ring: Caudal spine extending beyond posterior margin of anal valve and upturned distally.
Distribution: The species is known from one locality, namely Mt Ayliff in the Eastern Cape ( Fig. 3 View Fig ).
Remarks: Lawrence initially labelled the type material as Z. diplodonta , but this was because he had examined only the specimen with two spines on the telocoxal spine-plate, without dissecting out the gonopods. Z. diplodonta is distributed in the northern parts of the subregion, and the Eastern Cape locality falls far out of this range.
There is a degree of variation in the structure of the gonopods. One specimen has two telocoxal spines ( Fig. 177 View Figs 175–183 ) and the other has four ( Fig. 179 View Figs 175–183 ). In both cases one spine is further split into two, i.e. apically bifid.
