Rheumatobates minutus Hungerford, 1936

(Fig. 10)

In contrast to the two next species, R. minutus has a very wide distribution. Two subspecies distinguished by color are currently recognized: R. m. minutus (dorsum entirely dark) and R. m. flavidus (thorax dorsally yellow) (Hungerford 1954). The nominal subspecies has been recorded from Florida to Panama, including Puntarenas and San José provinces in Costa Rica, whereas R. m. flavidus has a more meridional distribution, from Puntarenas to northern Argentina (Drake & Harris 1942, Drake & Carvalho 1954, Hungerford 1954, Spangler et al. 1985, Polhemus & Spangler 1989, López-Ruf et al. 2003, Melo & Nieser 2004, Peralta-Argomeda 2011, Mazzucconi et al. 2009, Cunha et al. 2015, Cordeiro & Moreira 2015, Molano et al. 2018). The subspecific status of R. m. flavidus should be reevaluated because there seems to be a gradation of color patterns in Mesoamerica, sometimes with different forms in the same population (Polhemus & Spangler 1989). The material below represents what is currently considered R. m. flavidus and was collected close to sea level.
