Diagnosis.

Prefemur of the ultimate legs with four larger ventral spinous processes (Figure 5). Femur with two ventral and one medial spinous process, and tibia without (Figure 6). Femur and tibia without cylindric process at ventral corner of distal end; Femur equal to or a little longer than the tibia. Tarsus 1 not clavate. Tarsus 2 with 21 “pseudoarticles”. The tooth plates short (Figure 7), with the lateral side higher than the medial side, but differing from Tidops simus in being wider than long. Coxopleural process median to long.

Remarks.

The obscure and monotypic genus Kartops , that appears in a clade with Newportia and Tidops in Schileyko and Pavlinov (1997), was here examined for the first time since its description. Kartops was proposed by Archey (1923) for a scolopendromorph that clearly resembled Tidops , but according to him differed by three characters: (1) the number of spiracles, (2) presence of a "socketed spine tibialis" (i.e., a tibial spur), and (3) the anterior armor of the prosterum ( Archey 1923). Schileyko (2002) disputed the distinction between the two genera and placed Kartops in subjective synonymy with Tidops . The type species of Kartops , Kartops guyanae , is mounted on a slide, which is housed in the Canterbury Museum in New Zealand. The slide is in poor condition and it is only possible to verify the shape of the forcipula, which resembles that of all species of Tidops . Although the holotype does not allow the observation of many details described by Archey (1923), ten specimens from Kartabo, the type locality of Kartops guyanae , here identified as Tidops collaris , were examined and compared to the type material and the original description of Tidops collaris . The main characters used by Archey (1923) to diagnose Kartops , namely the number of spiracles, presence of a spur on the tibia and blunt processes on the anterior margin of the forcipular coxosternum are present in all species of Tidops . There are no details of the characters of the ultimate pair of legs that were lost when collected and so were not described. All other characters of Kartops guyane agree with those of the specimens from Kartabo. Therefore, Kartops guyane should be considered synonymous under Tidops collaris .

Type locality.

Bas Carsevenne, French Guyana (this locality now belongs to Amapá State, in Brazil).

Distribution.

French Guyana ( Kraepelin 1903, Attems 1930; Bücherl 1941a, b, 1974, Schileyko and Minelli 1999), Guyana, Venezuela (new record), Brazil and Paraguay ( Schileyko and Stagl 2004).
