Redescription
Body length from 40 to 70 mm. General body color light blue or olive green, sternites and legs light blue or yellowish; prefemur and femur of the ultimate legs light or dark blue, but sometimes tibia and tarsi are pale or light blue. Antennae with 17 to 21 articles, first two and dorsal surface and ¾ of the ventral surface of the third article are glabrous; antennae reaching the posterior margin of tergite 5. Cephalic plate smooth, with a median sulcus but without sutures or depressions (Fig. 1), wider than long. Anterior margin of cephalic plate right-angled, with four ocelli in each side, posterior margin slightly rounded (Fig. 1). Forcipular coxosternum without depressions (Fig. 2); tooth plates with 4+4, 4+5 or 5+5 teeth; the inner two teeth are closer to each other than to the external teeth (Fig. 3). Each tooth plate with a long seta in the center; the tooth plates with obtuse angled basal suture. Trochanteropreforal process well-developed, long and ending as a point, with three to five denticles laterally, these sometimes not visible (Fig. 4). Tergites smooth, wider than long. Tergite 1 without sutures, its anterior border overlapping the posterior border of the cephalic plate. Tergites 3–5 to 19–20 with complete paramedian sutures (Fig. 5). Tergites 5 to 21 marginate, usually from tergite 11 (Fig. 5), but sometimes also from tergite 16. The margination is clearly visible in the anterior part of the tergites; tergite 21 with a slight posterior depression and triangular posterior margin (Fig. 7). A pair of spiracles on the 7th leg -bearing segment. Sternites smooth, wider than long. Sternites 2 (4)-19 with short incomplete anterior sutures (Fig. 6). However, sometimes, they are overlapped by the posterior margin of the previous sternite and visible only at sternites 5–18. Sternite 21 longer than wide; converging caudad and with straight or slightly concave posterior margin (Fig. 8). Coxopleural pores of several sizes, and numerous; the pore-field occupies nearly all surface of coxopleuron except for its dorsal and posterior parts, which are free of pores, posterior part of coxopleuron with a longitudinal depression (Fig. 9); very short coxopleural process with two apical spines (Fig. 10); apical spines may be combined as 1+2 or 2+3. Leg 1 with one femoral spur and legs 1 and 2 with one tibial spurs; legs 1 to 16, 17 or from 2 to 18 with two tarsal spurs, 19 and 20 with one and 21 without. Sometimes legs 20 lack spurs. Pretarsi of all legs with two accessory spines. Ultimate legs long and slender (12 mm to 22 mm). Prefemur without spines.
Taxonomic remarks
Except for Rhysida maritima where the holotype and paratype were separated and given different numbers (e.g., holotype, MAGS 580a, and, paratype, MAGS 1002), the type specimens of all other species described by González-Sponga (2002)[7] were left united and were labeled with identical numbers (e.g., holotype, MAGS7400, and a paratype, MAGS740b). The acronym MAGS in the collection numbers stands for ‘Manuel Ángel Gonzalez Sponga’ and indicates that the specimens belong to his private collection, which after his death was transferred to the myriapodological collection of Museo del Intituto de Zoología Agrícola Francisco Fernández Yèpez, Maracay, Venezuela. The type series of Rhysida caripensis, Rhysida neoespartana, Rhysida monaguensis and Rhysida porlamarensis consists of more than two specimens. The recognition of the holotype is only possible by measuring the total body length, cephalic plate and ultimate legs and by checking them against the original publication (González-Sponga 2002[7]).
The results of the review of the type-material described by González-Sponga (2002)[7] are summarized in Table 1. The type of Rhysida celeris andina was not examined, but all characters (number of antennal articles, complete paramedian sutures and the margination of the tergites, sternite sutures, forcipular tooth-plates and tarsal spurs) fall within the intraspecific variation found in Rhysida celeris. Therefore, Rhysida celeris andina was also included in this revision, but the proposed synonymy is based solely on critical analysis of the published information (Bücherl 1953[8]).

Two other important characters that were omitted or were poorly described by González-Sponga (2002)[7] are the incomplete paramedian sutures on the sternites and the distribution of tarsal spurs on the legs. The incomplete paramedian sutures were not mentioned in his paper, although they are clearly visible from sternites 1 to 18, being more evident on sternites 6-15. The tarsal spurs were only described for Rhysida guayanica, Rhysida monaguensis and Rhysida porlamarensis, but their distribution were not indicated.
Rhysida celeris was originally described from ‘Carolina’ (Humbert and Saussure 1870[10], Saussure and Humbert 1872[1], Underwood 1887[11]) and later on recorded also from Georgia, USA (Pocock 1893[12], Kraepelin 1903[4], Attems 1930[5]). Crabill (1960)[13] stated that the North American records were not corroborated, and Shelley (2002)[14] deleted Rhysida celeris from the list of Scolopendromorpha of United States. Carolina is a common toponym in several countries in the Neotropical region. It exists in Puerto Rico, Cuba, Colombia (in the departments of Cesar, Antioquia and Magdalena), in Ecuador (in the departments of Guayas and Imbabura) and in Brazil. There is also a state of Carolina in the U.S. Virgin Islands, and also “La Carolina” in both, Mexico and Argentina. I did not examine the holotype of Rhysida celeris, but it is hosted (in alcohol) at the Myriapodological collection of Museum of Natural History of Genève, Switzerland. The specimen is labeled “Branchiostoma celer Humbert & Saussure, type, from Caroline”. A second label reads “revision R. E. Crabill, back 1970” (Peter Schwendinger, personal communication). I do not know any other additional information on the type locality, therefore, the exact whereabouts of the type locality remains uncertain. However, it is more likely that the specimen had been collected somewhere in Antilles, Central or South America rather than in the USA.
Distribution
Jamaica, Dominican Republic, Haiti, Nicaragua (Meinert 1886[3]), Venezuela (Bücherl 1942[6], 1959[15]), Mexico (Kraepelin 1903[4], Attems 1930[5], Bücherl 1942[6]), Bolivia (Silvestri 1897[16]), Argentina (Bücherl 1942[6]), Brazil (Kraepelin 1903[4], Attems 1930[5], Bücherl 1942[6], Schileyko 2002[17]), Colombia (Chamberlin 1921[18]), Ecuador, Peru (Bücherl 1950[19], Kraus 1957[20]), Suriname and Paraguay (Silvestri 1895[21]).
