Comment | MARX 1958 listed FMNH 95836 as cotype, implying that the “type” was among the remaining ZMB specimens. DIXON et al. (in GOLAY et al. 1993) regarded ZMB 6659 as the lectotype, apparently accepting MARX’s action as an implicit designation. However, as two specimens remain under this number in Berlin, no action to date has selected a single lectotype and all members of the type series should be regarded as syntypes (from BAUER 1995). Venomous! The common name is derived from the Balsas river in south-central Mexico, along which this species appears to occur. |
Etymology | Latin from lati- meaning broad or wide and collari meaning of the collar, referring to the long black nuchal band. M. l. maculirostris was named after Latin macular = spot, and rostrum = beak, proboscis, trunk, alluding to the light dots on the snout. |
