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.

Material examined. Limón— Moín, Turbia Stream, 1400 m before confluence with another river, site 3, 3.VII.2012, (X. González): 1 male (MZUCR).
