description: SUBGENUS UDAMOCHIRAS ENDERLEIN STAT. NOV.   
 Udamochiras Enderlein, 1912: 42. Type species: U. colossia Enderlein, by original description 1924: 281.   
 Diagnosis. Abdominal tergites laterally with large, bristle-like setae as long as tergal length (Fig. 16). Mid and hind leg with anterodorsal row of large setae (Fig. 15). All legs with bifurcate tarsal claws in females.   
 Characters shared by most or all species. See Figure 22 for a habitus photograph of a typical species.   
 Head. Fronto-orbital and interfrontal setal bases surrounded by sulcus that delimits oval setal base (which is also found in at least some Phalacrotophora species); setal base in some species coloured differently than rest of frons. Basal one-half of flagellomere 1 white, distally one-half yellow; arista yellow at base, apically black. Palpus yellow with yellow, flattened setae along ventral length and one longer, apicoventral, black seta. Ocular and genal setae flattened, yellow.   
 Thorax. Scutum blackish-brown. Scutellum dark brown with silver pollinosity; with posterior pair of setae much longer than anterior pair. Thoracic pleuron dark brown with silver pollinosity, except katepisternum, which lacks all but posterodorsal pollinosity. Coxae whitish-yellow; fore coxa anteriorly with silver pollinosity. Fore femur and tibia yellowish-brown. Fore tibia with posterodorsal bare region, bounded anteriorly by row of enlarged, widely spaced setae and more anterior, row of larger setae, and posteriorly by row of larger, posterodorsal setae. Mid femur and tibia yellowish-brown; mid tibia with one dorsal setal palisade extending entire length and few anterodorsal, irregular palisades basally. Mid tibia with anterodorsal row of enlarged setae and posterodorsal row of larger setae that extends to apical one-third of tibia. Mid tarsomeres thin, yellowish-brown, elongate; claws finely bifurcate at apex. Hind femur yellowish-brown with dark brown macula at apex; hind tibia yellowishbrown. Hind tibia with anterodorsal row of enlarged setae extending to mid-length and posterodorsal row of larger setae that extend entire length of tibia and that increase in size posteriorly; with several irregular, anterodorsal setal palisades. Hind tarsomeres thin, yellowish-brown, elongate; claws finely bifurcate at apex. Wing vein R 2+3 absent. Halter pale yellow.   
 Abdomen. Abdominal tergites black, with anterior regions of silver pollinosity. Venter of abdomen grey. Stylet as in Figures 13, 14, with ventral processes shorter than dorsal apex.   
 Hosts. The only published host record of a species of Udamochiras is that of Ronna, 1936, 1937) who reared M. ronnai from honey bees, Apis mellifera. In addition to the new records listed in the species treatments below (and summarized in Table 1), I reared a male Udamochiras of an unknown species from Cephalotrigona capitata (F. Smith) at La Selva Biological Station, Costa Rica, during a study on Apocephalus Coquillett (Diptera: Phoridae) parasitoids of stingless bees (Brown, 1997). The bee host was collected alive on 26.iii.1995 and the adult fly emerged 22.iv.1995, giving a minimum of 27 days for the fly’s immature stages.
