Remarks. This subspecies is recorded from Colombia and Venezuela . It inhabits lowland streams with waterfalls inside forest (between 0 and 450m . a.s.l.) along the Magdalena River Valley and extends northwest to the foothills of the Cordillera de Merida in Táchira and Trujillo States ( De Marmels 2008 ). We found some variation on abdominal coloration with dorsum of S9 brown to black ( Fig. 7b ). It is sympatric with H. aequatoriale and H. erythrogastrum in different localities (see information above in the biology section of these species). New localities are recorded at Antioquia and Caldas Departments ( Fig. 2 ).
