6573CDD71D425FF0AF74C1A06F70EF7C.taxon	etymology	Etymology. The name of this species refers to the Arhuaco people with ancestral lands close to the type locality of the species. The Arhuaco people self-identify as Iku, which translates as “ people ” in the Ika language (Tracy 1997). Iku (Arhuacos) - Guardians of life, defenders of the peaceful coexistence of men among themselves and with the forces of nature. This is a name in apposition and thus invariable.	en	Arredondo, Brandon S., Guerrero, Roberto J.

BC051E13C8215581A9840E21F9F60A48.taxon	diagnosis	Diagnosis. Frontal lobe projected laterally, covering the antennal insertions. Frontal carina extending to posterior cephalic vertex, forming a weak scrobus. Dorsum of mesosoma straight and flattened. Lateral margin of pronotum straight, converging towards mesonotum. Lateral projection of the mesonotum dentate. Lateral dorsopropodeal processes long, covering propodeal spiracle in dorsal view.	en	Arredondo, Brandon S., Guerrero, Roberto J.

BC051E13C8215581A9840E21F9F60A48.taxon	description	Description. Worker. In full-face view, head longer than wide (CI 85 – 86), slightly narrowing behind the eyes; occipital margin weakly convex; occipital angles rounded; lateral margins slightly curved posteriorly; anterior margin of clypeus weakly convex, projecting over mandibles; eyes lateral, with 10 ommatidia at greatest diameter; frontal lobes laterally expanded, antennal insertions completely hidden by frontal lobes; frontal carina extending to posterior cephalic vertex, as if forming a weak scrobus; antenna with 12 antennomeres; mandible triangular; inner margin with five teeth, separated from basal margin by fifth tooth; scapes short (SI 72 – 73) barely reaching posterior margin of eye, curved towards mid-length; pedicel longer than wide, and almost as long as next three antennomeres together; antennal club with three antennomeres. Mesosoma. In lateral view, mesosomal profile straight; in dorsal view, pronotum wider than long, with its maximum width towards anterior margin, the latter slightly convex, humeral angle angulated, lateral margins of pronotum curved; in lateral view, promesonotal suture present, in dorsal view, absent; in dorsal view, mesosomal lateral projection angulate; dorsopropodeal lateral projection angulate, projecting over propodeal spiracles; propodeal spines short, less than half the distance between their apices in length, and divergent; in lateral view, propodeal spiracle small (diameter = 0.057 mm), approximately equal to the length of the 10 th antennomere, circular, projected posterolaterally; propodeal lobe short and uniformly rounded. Metasoma. In dorsal view, petiole trapezoidal, anterior margin shorter than posterior margin; posterior margin with two mesial tubercles of equal length; lateral margins diverging from anterior to posterior margin; lateral margin with two posterolaterals tubercles; in anteroposterior direction, first tubercle poorly developed, length less than half the total length of the following tubercle; in lateral view, petiole subquadrate, peduncle and petiolar node without apparent differentiation, forming a continuous outline, which extends to the dorsal surface of the petiolar node; anterior surface of petiole with anteromedial petiolar spine on each side, superior to the petiolar spiracle; dorsal surface weakly rounded and short; anteroventral process of petiole acute; in dorsal view, postpetiole hexagonal, twice as wide as long; in lateral view postpetiole globose, taller than long. Sculpture. Body generally opaque, with smooth, shiny areas restricted to gaster; dorsal surface of body rugose-reticulate, excluding gaster; lateral surface of mesosoma reticulate; clypeus smooth and shiny, with medial longitudinal carina; dorsal surface of mandibles shiny, with weakly marked striation; scape and legs shiny with superficial sculpture; gaster weakly imbricate. Pilosity and color. Dorsal surface of body with flattened erect hairs, mostly separated by a distance equal to or greater than its length; hairs as long as the base of the propodeal spines; in full-face view, head capsule with erect hairs restricted to the clypeus, area between the frontal carinae and vertex; scapes covered with short decumbent hairs, without erect hairs; propodeal spines with erect hairs; legs with simple, appressed, sparse hairs restricted to the apex of the femora; gaster with abundant erect hairs, separated by a distance equal to its length. Body pale yellow, legs slightly paler, base and apex of femur and tibia darker. Queen and male. Unknown.	en	Arredondo, Brandon S., Guerrero, Roberto J.

BC051E13C8215581A9840E21F9F60A48.taxon	etymology	Etymology. The epithet xerophilus is a word composed of the prefix xero - (from ancient Greek ξηρο - meaning dry) and the suffix - philo or - philus (from ancient Greek φίλος meaning attraction towards). The species epithet refers to the dry habitat where these ants live, that is, the tropical dry forest, a life zone highly threatened by the high rate of deforestation in Colombia. It is a noun in apposition and thus invariant.	en	Arredondo, Brandon S., Guerrero, Roberto J.
