Species delimitation, environmental cline and phylogeny for a new Neotropical genus of Cryptinae (Ichneumonidae)

Two new Darwin wasp species of Eiphosoma Cresson, 1865 (Ichneumonidae: Cremastinae) from the northwestern Andes of Colombia

Two new Darwin wasp species of Eiphosoma Cresson, 1865 (E. nigroandinum Fernandes sp. nov. and E. merceae Fernandes sp. nov.) are described from the northwestern Andes of Colombia. Furthermore, we propose the establishment of a new species-group, E. nigroandinum species-group, to encompass these newly described species. Additionally, we expand the geographical distribution of Eiphosoma vitticolle Cresson, 1865, and complement the findings with a map and digital images.

Five new species of Eiphosoma Cresson, 1865 (Ichneumonidae: Cremastinae) from Colombia, new records, and a key to Colombian species

A taxonomic study of the species of the Darwin wasp genus Eiphosoma Cresson, 1865 (Hymenoptera: Ichneumonidae: Cremastinae) from the department of Caquet, Colombia, resulted in five new species being described: E. caqueta sp. nov. (Type locality: Curillo, Caquet), E. eneke sp. nov. (Type locality: San Vicente del Cagun, Caquet) E. interpunctum sp. nov. (Type locality: Solano, Caquet,), E. rumi sp. nov. (Type locality: Florencia, Caquet) and E. sinecarenatum sp. nov. (Type locality: Florencia, Caquet). With this paper, the number of Eiphosoma species from Colombia increases from three to 16. Eiphosoma bogan Gauld, 2000; E. dentator (Fabricius, 1804); E. dolopon Gauld, 2000; E. fluminense Costa Lima, 1953; E. fuzhi Gauld, 2000; E. macrum (Enderlein, 1921); E. minense Costa Lima, 1953 and E. tantalium Gauld, 2000 are recorded for the first time from Colombia. A dichotomous key to the Colombian species is presented.
