Abstract
Nine new species of Itaplectops Townsend (Diptera: Tachinidae) are described from Area de Conservación Guanacaste (ACG), northwestern Costa Rica. All specimens have been reared from -various species of ACG caterpillars in the families Limacodidae and Dalceridae. By combining morphological, photographic, and genetic barcode data we provide clear yet concise descriptions. The following nine new species are described in the genus Itaplectops: Itaplectops akselpalolai, Itaplectops anikenpalolae, Itaplectops argentifrons, Itaplectops aurifrons, Itaplectops ericpalolai, Itaplectops griseobasis, Itaplectops omissus, Itaplectops shellymcsweeneyae, Itaplectops tristanpalolai. We move Itaplectops to the tribe Uramyini from its original placement within the Blondeliini, and we discuss its systematic placement. We also provide a key differentiating the, genera of the tribe Uramyini as well as the known species of Itaplectops.Entities:

| 1 | Abdominal T5 usually extended dorsally beyond the genitalia, into a tail-like process; proclinate orbital bristles only present in females; T3, T4, and T5 with two or three, rarely one pair of median discal bristles; if no tail present then mid-dorsal depression on T1+2 extending almost to tergal margin | |
| – | Abdominal T5 normal, dorsally with a truncate appearance; two strong proclinate orbital bristles; inner and outer vertical bristles strong, median discal bristles ranging from absent to only one pair present; mid-dorsal depression on T1+2 not extending to tergal margin |
|
| 2 | Three katepisternal bristles; discal bristles absent on scutellum; discal bristles present on T4 | |
| – | Two katepisternal bristles; discal bristles present on scutellum; discal bristles absent on T4 |
This key has been adapted from Guimarães (1980) to include the genus Townsend; this key is valid for both sexes.
| 1 | First flagellomere pale orange |
|
| – | First flagellomere a darker orange brown |
|
| 2 | Median marginal bristles present on T3; apical scutellar bristles short, up to 1/2 the length of subapical scutellars; femur mostly dark, paler at apex (concolorous with tibia) |
|
| – | Median marginal bristles absent on T3; apical scutellar bristles long at least 1/2 the length of subapical scutellars; femur mostly yellow, darkened at base | 3 |
| 3 | Parafacial with 1 bristle arising near midway, between lowest frontal bristle and facial margin | |
| – | Parafacial bare |
|
| 4 | Parafacial haired, bearing at least a few sparse bristles midway |
|
| – | Parafacial bare, devoid of any bristles below lowest frontal bristles |
|
| 5 | Fronto-orbital plate with small hairs interspersed throughout and not confined to a row outside of frontal bristles, hairs extending into frontal vitta; frontal vitta with silver sheen when viewed from the front; legs dark with yellow ground color on joints, yellow tibia and dark tarsi. |
|
| – | Fronto-orbital plate with small hairs confined to a row outside of frontal bristles, hairs not extending into frontal vitta; frontal vitta bearing a gold sheen when viewed from the front; legs dark with yellow ground color on joints, yellow tibia and yellow tarsi |
|
| 6 | Subapical scutellar bristles either parallel or convergent (frequently crossed); anterior katepisternal arising behind pleural suture; median marginal bristles absent on T1+2, discal bristles absent |
|
| – | Subapical scutellar bristles divergent; anterior katepisternal arising below or slightly anterior to pleural suture; median marginal bristles present or absent on T1+2 discal bristles present at least on T3 |
|
| 7 | Fronto-orbital plate entirely golden tinged; facial ridge bearing at least 8 stout decumbent bristles |
|
| – | Fronto-orbital plate entirely silver; facial ridge bearing at most 4 stout decumbent bristles |
|
| 8 | Median marginal bristles absent on T1+2; 3 postsutural supra-alar bristles; apical scutellar bristles short, up to 1/2 as long as subapical scutellars; femur yellow, tibia yellow, and dark tarsi |
