( Figures 1A,E , 2E , 3E , 4E , 5E ) Diagnosis Frontal vitta dark brown; scape and pedicel yellow; length of postpedicel.1.5 times the length of pedicel; arista with short pubescence, rays shorter than width of base of arista; scutum with three brown vittae, dc vitta not well-delimited due to pollinosity on scutum; sternite 5 with two long apical processes, with long setae and strong spines on inner apical region; cercal plate formed by cerci fused on apical half (V-shaped), apex square. Description Male holotype . Body length 2.7 mm ; wing length 3.0 mm. Head. Eye bare. Frontal vitta dark brown. Interocular space 0.5 mm . Three pairs of fr , two of which are more developed and converging, with intercalated setulae between them. Orb two pairs, anterior pair lateroclinate, posterior pair reclinate. Ocellar tubercle grey pollinose; oc proclinate and developed, one pair of setae weaker than the others, tubercle area with two short setulae. Poc divergent. Fronto-orbital plate, parafacial and gena greyish. Parafacial with short setae on dorsal half. Scape and pedicel yellow. Postpedicel dark brown, golden yellow pollinose, 1.5 times the length of pedicel. Arista brown with short pubescence, rays shorter than width of base of arista. Palpus dark brown, spatulate. Thorax. Greyish with golden yellow pollinosity, scutum with golden yellow pollinosity, three brownish vittae, along acr and dc rows, the vittae on dc row mixed with pollinosity on scutum. Acr 2:3, in irregular rows. Dc 2:3, first presutural seta shorter than half the length of second presutural seta. Postpronotum with two well-developed setae and a weaker seta. Pra two, both well developed. Proepimeral setae two, seta closest to spiracle longer, second seta weakly differentiated, proepimeron without setulae. Katepisternal setae 1:1, with one weakly developed between them, katepisternum with short setulae. Wing. Yellowish. Calypter whitish with yellowish margins. Haltere yellowish. Legs. Coxae and femora dark brown, fore and mid trochanters yellow, apex of femora and tibiae yellow; tarsi dark brown with whitish pulvilli. Fore femur on av surface with a row of short setae; pd surface with a row of long, subequal setae; p surface with two rows of setae shorter than pd setae; pv surface with a row of long setae on apical half; v surface bare. Fore tibia on d surface with a pre-apical seta; ad surface with a seta at the limit of apical third and an apical seta; av surface without differentiated setae; pv surface with an apical seta; v surface with an apical seta. Fore first tarsomere with one differentiated basal setae on v surface. Mid femur on av surface with a row of sparse setae; pv surface with two rows of setae, most setae curved apically and forming a ctenidium on apical half; p surface with three pre-apical differentiated setae. Mid tibia on v and a surfaces with a developed apical seta; ad surface with a seta on limit of apical third and a pre-apical seta; v surface setulose, with short and weak setae; pd surface with a developed pre-apical seta; p surface with a median and two short pre-apical setae; pv surface with a short apical seta; d surface with a developed pre-apical seta. Hind coxa setulose on posterior margin. Hind femur on apical half of ad surface with thre or four developed setae; av surface on apical third with two developed setae; v surface bare; d surface with a short seta on apical third; pd surface with a short seta on apical third. Hind tibia on d surface with a median seta and a developed pre-apical seta; ad surface with a median developed seta, at the same level as d median seta and a shorter pre-apical seta; av surface with a median seta and a pre-apical developed seta; pv surface with a short apical seta. Abdomen. Grey with faint golden yellow pollinosity. Sternite 1 bare. Sternite 5 ( Figure 2E ): wide, with two long apical extensions, ample on median portion, with long setae and strong spines on internal surface of apical portion. Terminalia ( Figures 3E , 4E ): epandrium longer than wide and bearing long setae; surstylus long, almost the same length as epandrium, narrow, curved and articulated with epandrium, inner surface setulose basally and apical region with short setae with clearly visible sockets; cercal plate fused on apical half (V-shaped), square apex. Hypandrium and associated structures as in Figure 5E . Female. Unknown. Variation Some specimens with scape dark brown and pedicel dark brown with anterior margin and suture yellow; vittae on scutum occasionally not very conspicuously differentiated from pollinosity on scutum, or better defined when scutum is faintly pollinose. Biological notes According to collecting label data this species has potential forensic utility for the departments of Cundinamarca and Boyacá in Colombia because it is associated with carrion. Comments As part of the material examined there were some females from the same locality and collection (decomposing pig carrion). However, it is difficult to be sure that they belong to the same species as the male. Etymology The specific epithet, muisca , refers to the indigenous people Muiscas that inhabited the “Altiplano Cundiboyacense” formed by high plains on the east side of the Colombian Andes between the departments of Cundinamarca and Boyacá , type locality of the species.
