Eye red and bare; ocelli on large tubercle, well in front of vertex, ocelli minute, anterior ocellus divided at middle into two minute ocelli, anterior ocellus with lateral dark line that reaches lateral ocelli, ocelli surrounded by black spot; vertex yellow with a brown transverse fascia covered with brown pile, frons yellow with an arched brown mark above antennal fossa; face yellow, sparsely covered with pale pile; yellow gena reduced and narrow; post-ocular orbit yellow, narrow laterally, with black pile; occiput yellow, with yellow and black pile; scape dark-brown, elongated, about 1/4 of length of basoflagellomere; pedicel dark-brown, reduced, with short black pile on anteroapical margin; basoflagellomere very long, laterally flattened, light-brown except for yellow tip; arista minute, spine-like, yellowish and bare. Thorax. Mesoscutum orange with a small median black spot on anterior margin and with wide lateral black vittae that do not reach the anterior and posterior margins, covered with golden pile on presutural area and black pile on mesonotum; postpronotum yellow; notopleuron black; postalar callus yellow, with black pile; scutellum orange, covered predominantly with black pile and with three pairs of apical golden setae, divided into two lobes by a cleft in the middle of the posterior margin (Fig. 15); pleuron yellow, except for black meron, katepimeron and anatergum, dark anterior part of anepisternum, and posterior margin of katepisternum; anepisternum with black and golden pile on dorsal half; anepimerom with black and golden pile on posterodorsal corner; katatergum covered with golden pile on posterior corner; katepisternum with median golden pile on dorsal margin. Legs. Procoxa yellow with black mark dorsally, with golden pile on posterior margin of anterior surface; mesocoxa black with golden pile on posterior margin; metacoxa yellow with black pile dorsally and golden pile ventrally; trochanters black with black pile; pro- and mesofemora yellow with yellow pile; metafemur brown; pro- and mesotibiae yellow; metatibia flattened laterally, black, except for yellow distal portion, with an oblique orange cicatrix; all tarsi reddish with golden pile, tarsal claws black.

Type material. Holotype f# labeled as follows: “ Brasil Pará/ Serra Norte/ Est. MANGAN/ 13 a 16.8.1984 [White label with printed and handwritten information]”; “Armadilha/ 20m / suspensa [= suspended trap at a height of 20 meters] [White label with printed and handwritten information]”; “ MPEG DIP / 12170377 [White label with printed information]”. Specimen in good condition. Paratype f# labeled as follow: “ Brasil Pará/ Serra Norte/ Est. Manganês/ 5 a 9.IX.1983 [White label with printed and handwrite information]”; “Armadilha/ suspensa/ 1,6m [= suspended trap at a height of 1.6 meters] [White label with printed and handwrite information]”; “ MPEG DIP / 12170506 [White label with printed information]”. Specimen in good condition, with head and antennae glued on a piece of cardboard pinned with the specimen.
Etymology: Jataí is the common name for some stingless bees of the genus Tetragonisca Moure (Hymenoptera: Apidae) in Brazil, alluding to the similarity of Carreramyia jatai to some Tetragonisca species. It should be treated as a noun in apposition.
Geographic distribution: Brazil (Pará).
Remarks. Carreramyia jatai sp. n. is similar to C. flava (Sack) in having abdomen and thorax yellowish and with brown marks. However, C. flava differs from C. jatai sp. n. in having a basoflagellomere with a conspicuous median protuberance just distal of the insertion of the arista; frons with two separated brown spots, one on each side of the antennal fossa, and vertex and scutellum covered with yellow pile (see Reemer (2013) for a detailed redescription of the species). In C. jatai sp. n. the frons has only one large brown spot located dorsad of the antennal fossa and extending laterally to it; the pile of the thorax is dark-brown and the pile of scutellum is yellow basally and black apically, and the median protuberance of the basoflagellomere is absent (Figs 17, 18).
