The bolivar species-group contains two species, M. bolivar and M. carvalhoi , originally described in the genus Giovanella then moved to Huascaromusca ( Marinho et al. 2017 ) , the two new species M. epandrioaurantia sp. nov. and M. woodorum sp. nov. These four species share anterior spiracle with a long, narrow opening gradually widening above ( Fig. 6 ), rather than a broad oval opening above; discal scutellar setae absent; and 2x 2 postpronotal setae. The epandrium, cerci and surstyli of M. bolivar ( Figs 37–38 ) and M. carvalhoi ( Wolff et al . 2017 : figs 10–11) are very similar, but they are very different from those of M. epandrioaurantia sp. nov. and M. woodorum sp. nov. ( Figs 31–34 ). As more species are described this group may be split, but for now they are placed together based on the shared morphological characters listed above. Barcodes were obtained only for M. epandrioaurantia sp. nov. , which formed a distinct group (see discussion under that species).
