Antrops tequendama View in CoL sp. nov.

( Figs. 82–84 View FIGURES 79–84 , 212 View FIGURES 204–212 )

Description. Head orange, medial occipital sclerite brown. Occiput and gena covered with microtomentum, frons shiny except extreme anterior corners with microtomentum, face shiny with a small spot of microtomentum below lunule. Ocellar, posterior orbital, and outer vertical bristles absent. Subvibrissal bristle about 0.4X length of vibrissa, anterior genal bristle not developed. Gena about 0.5X eye height. Number of pseudotrachea on labellum unknown.

Thorax black, mostly shiny. Microtomentum at lateral corners and just lateral to scutellum, on dorsal third of anepisternum, covering katepisternum except spot behind fore coxa, covering anepimeron except anterodorsal corner, and covering laterotergite. Anterior notopleural and lateral postalar bristles long, postpronotal, presutural intra-alar, posterior notopleural, posterior postsutural dorsocentral, and medial postalar bristles short. Scutellar and katepisternal bristles broken on holotype, other bristles appear to be absent or indistinguishable from surrounding setae. Wing and halter absent.

Legs black, shiny, trochanters, joints, and tarsi brown. Mid tibia with 1 anterodorsal, 1 anteroventral, 1 posteroventral, and 4 apical bristles. Hind tibia with 2 ventroapical bristles.

Abdominal tergites heavily sclerotized, black, shiny. Sternite 2 heavily sclerotized, black, shiny, sternites 3–4 weakly sclerotized.

Male postabdomen: Sternite 5 flared and emarginated posteriorly, anterior apodeme about as long as external portion, without keel ( Fig. 84 View FIGURES 79–84 ). Surstylus subrectangular with a curved anterior projection, anterior corner with a row of stout setae ( Fig. 83 View FIGURES 79–84 ). Pregonite small, distinct. Postgonite with long lobe, anterior lobe very thin, posterior lobe wider, pointed apically. Basiphallus without distinct epiphallus, preepiphallus very short. Distiphallus with a strongly curved, smooth dorsal tube ( Fig. 82 View FIGURES 79–84 ).

Female unknown.

Type material. Holotype ♂: COLOMBIA: Cundimarca : “ C. Amara ”, Tequendama, 7600′, 6 Jul 1970, J. M. Campbell, debu01154923 ( CNCI).

Comments. The holotype has some broken bristles on the head and thorax and is somewhat greasy, but is otherwise in good condition. There are no sockets present for the bristles noted as missing in the description, and they do not appear to be merely broken off. It is unclear what the name “C. Amara” on the label of the holotype refers to. It may be a poorly transcribed abbreviation for Cundimarca, the department which includes the municipality of Tequendama. The species name is derived from the type locality and should be treated as a noun in apposition. The surstylus of this species is quite striking and rather distinct from any other species in the genus.
