Diagnostic description: 

Diagnosis from Chagas-Jr. (2013: 21)[1]: General body color light blue or olive green, sternites and legs light blue or yellowish; prefemur and femur of the ultimate legs light blue, sometimes tibiae and tarsi are pale. Antennae with 17 to 21 articles, first two articles, dorsal surface and ¾ of ventral surface of third articles glabrous. Cephalic plate smooth, without sutures or depressions; tooth plates wider than high, 4+4, 4+5 or 5+5 teeth. Tergites smooth; complete paramedian sutures present from tergites 3–5 to 19–20, margination from tergites 5–9 to 21. Posterior border of tergite 21 ending in an obtuse angle. A pair of spiracles at 7th leg-bearing segment. Sternites 2, 3 or 4 to 19 with anterior incomplete paramedian sutures, but without depressions. Coxopleuron not prolonged, very short process with two small apical spines. Legs 1 to 16 (or 17) or 2 to 18 (sometimes 17) with two tarsal spurs, 19 (or 20) with one and 21 without; ultimate legs long, prefemur without spines.

Distribution: 

Distribution: Caribbean: New Providence, Cuba, Jamaica, Dominican Republic, Haiti, Montserrat, Trinidad. North America: Mexico, Nicaragua, Costa Rica. South America: Colombia, Venezuela, Suriname, Ecuador, Peru, Bolivia, Brazil, Paraguay, Argentina. [24.02.2022]

The record from New Providence (Bahamas) by Chamberlin (1918: 155)[1] has been missed by subsequent authors.

Distribution from Chagas-Jr. (2013: 25)[2]: Jamaica, Dominican Republic, Haiti, Nicaragua (Meinert 1886), Venezuela (Bücherl 1942, 1959), Mexico (Kraepelin 1903, Attems 1930, Bücherl 1942), Bolivia (Silvestri 1897), Argentina (Bücherl 1942), Brazil (Kraepelin 1903, Attems 1930, Bücherl 1942, Schileyko 2002), Colombia (Chamberlin 1921), Ecuador, Peru (Bücherl 1950, Kraus 1957), Suriname and Paraguay (Silvestri 1895). From that summary list are missing Costa Rica and Montserrat. According to Chagas-Jr. (2013: 26), "The species is herewith recorded from the Dominican Republic, Haiti, Montserrat, Suriname and Ecuador for the first time." but Costa Rica is not mentioned either. Chagas-Jr. (2013: 19-21) gave detailed specimen localities and a distribution map was presented by Chagas-Jr. (2013: 26).

Reported from Cuba by Schileyko (2014: 183)[3], who missed Costa Rica and Montserrat in his summary list but included "Southern USA". The latter range is unjustified, as Rhysida celeris was deleted by Shelley (2002: 5)[4] from the list of Scolopendromorpha of United States, an action followed by Chagas-Jr. (2013: 25).

Reported from Trinidad by Joshi et al. (2019: 3)[5].

Not reported from: Saint Barthélemy (Schileyko, 2018)[6], Martinique (Schileyko et al., 2018)[7].
