A review of the centipede genus Tidops Chamberlin (Scolopendromorpha, Scolopocryptopidae, Newportiinae) Author Chagas-Junior, Amazonas text International Journal of Myriapodology 2011 5 63 82 http://dx.doi.org/10.3897/ijm.5.1649 journal article http://dx.doi.org/10.3897/ijm.5.1649 1875-2543--63 Tidops simus Chamberlin, 1915 Tidops simus Chamberlin, 1915: 496. Attems, 1930: 285. Schileyko & Minelli, 1999: 296. Schileyko & Stagl, 2004: 125. Type material: Holotype (MCZ 14550, examined) GRENADA: Richmond Hill, 1910, coll. G. M. Allen and C. T. Brues. Additional material: (ZMUC) 1 specimen, BRAZIL: "Brasilien" , Para , Santarem , Taperinha, 9-XI-1970, Ove Jensen. Diagnosis. Prefemur of the ultimate legs with three ventral spinal processes, and femur with two. With a cylindric process at ventral corner of distal end of the tibia of the ultimate legs. Tarsus 1 of the ultimate legs clavate. (cf. Chamberlin (1915) plate 1, fig. 6). Femur and tibia of equal length; second tarsus divided into 9-11 "pseudoarticles" . Tooth plates dentiform longer than wide. Coxopleural process medium to short. Remarks. The holotype of Tidops simus is mounted on a slide and almost all pieces are broken. The specimen has been mounted ventrally and it is not possible to examine characters of the dorsal part and the legs, which are missing. The only relevant character which could be observed was the forcipular coxosternum. I have found a specimen of Tidops from Brazil that was assigned as Tidops simus mainly on the characters of the ultimate legs and the tooth plates (i.e., their diagnostic length/width ratio). The prefemur of the ultimate legs has a series of three ventral spinous processes and the femur one or two. The tibia has a cylindric process at ventral corner of distal end and tarsus 1 clavate as described to the holotype of Tidops simus by Chamberlin (1915) . Different from the holotype, the specimen from Brazil showed a very short expansion at ventral corner of distal end of the femur. Tarsus 2 is divided into 11 articles in one leg and 9 in the other. The tooth plates are longer than wide. Type locality. Richmond Hill, Grenada. Distribution. Grenada and Brazil (new record).
