Polydesmus integratus Porat, 1894: 30 (original description).

Type material.

Lectotype ♂ (Naturhistoriska riksmuseet, Stockholm), Cameroon, leg. Y. Sjöstedt.

Paralectotypes: 2 fragmented ♀♀ (Naturhistoriska riksmuseet, Stockholm), together with lectotype.

One of us (JPM) revised the types and made the present lectotype designation, the latter to ensure that the species is based on male material.

Diagnosis.

Differs from other species of the genus by 20 body segments, the presence of a boletiform epicranial tubercle (♂), coupled with the gonopodal telopodites which are deeply sunken inside a large gonocoel and show only one, flagelliform, basal, main branch (bb) exposed beyond the coxa. The solenomere (sl) is short and finger-shaped (Figs 27F, G).

Descriptive notes.

Length of lectotype ca. 8 mm, width of midbody pro- and metazonae 0.6 and 1.1 mm (♂), respectively. Coloration in alcohol red-brown ( Porat 1894).

Body with 20 segments. Pore formula normal, but slightly abbreviated: 5, 7, 9, 10, 12, 13, 15-17. Head with a distinct, epicranial, boletiform tubercle (♂)(Figure 27A, B). Interantennal isthmus ca. 1.5 times as broad as diameter of antennal socket (Figure 27A). In width, head = collum <segment 2 (Figure 27B). Paraterga relatively well-developed (Figure 27 C–E), mostly slightly upturned caudally. Tarsal brushes present (♂).

Gonopodal telopodites deeply sunken inside a large gonocoel and showing only one, flagelliform, basal, main branch (bb) exposed beyond coxa; solenomere (sl) short and finger-shaped (Figs 27F, G).
