A new genus and a new species of treehopper (Hemiptera: Membracidae) from the páramo of Tatamá in Colombia.

The treehopper fauna of páramos has been poorly studied. Here, the new genus Oropedium is described to accommodate the new species Oropedium tatamaense, found in the unexplored páramo of Tatamá at 3750 masl (Cordillera Occidental, Colombia). This taxon could not be classified in any known tribe of the subfamily Membracinae and is placed as incertae sedis.

Andinodarnis gen. nov., a new treehopper genus from the Andes (Hemiptera: Membracidae: Darninae).

Andinodarnis gen. nov. (Darninae: Darnini) is proposed based on recently collected treehoppers from the Northern Andes.

A new species of Sakakibara (Membracidae: Smiliinae: Acutalini) from Colombia.

The genus Cornutalis Sakakibara currently includes two valid species, Cornutalis cauca Sakakibara, 1997 (from Colombia) and C. valida Sakakibara, 1997 (from Ecuador). Herein, a new species, Cornutalis andinum sp.

Contribution to the taxonomy of the family Membracidae Rafinesque (Hemiptera: Auchenorrhyncha) in Colombia.

The Membracidae are a relatively diverse group with nearly 400 genera and 3200 species. For Colombia 93 genera and 394 species were previously known. Study of the literature and 3744 specimens deposited in ten colections in Colombia, as well as non-systematic collections and field observations done in Colombia between 2011 and 2014, led us to record 116 genera and 474 species grouped in 9 subfamilies and 23 tribes, distributed in 24 departments.

The identity of the treehopper genus Dysyncritus Fowler, with descriptions of new related taxa (Hemiptera: Membracidae: Heteronotinae).
