( Figs. 8 View FIGURE 8 A–C)

Type material. ♂, labeled: HOLOTYPE, Olbiogaster puuc sp. nov. MEXICO, Yucatan, Reserva Estatal Biocultural del Puuc, 7-October-2015, CDC Trap, Sitio 3, GPS: 20° 13' 44.92" N; 89° 32' 57.11" W; Col. Navarrete-Carballo, J.C. GoogleMaps

Diagnosis. Male: thorax dark brown, mesonotum with central stripe and pale dorsocentral line; coxae dark brown; forefemur with distal half yellow, half basal dark brown; midfemur yellow, except for basal dark brown ring; hind femur dark brown; haltere pale brown. Abdomen dark brown. Gonostylus with two elongated subapically setae, one inserted subbasally on the spine.

Description. Body length (including the antenna), 8.5 mm.

Head. Very similar to the description of O. nuxco . Scape almost entirely yellow; pedicel brown, black pilosity; flagellum black, with 11 cylindrical flagellomeres (12–14 lost flagellomeres), about 1.2 times as long as wide, flagellomeres with scattered setae.

Thorax. ( Fig. 8 View FIGURE 8 A–B). Dark brown, mesonotum with central stripe and pale lateral margins, covered with fine whitish setulae ( Fig. 8B View FIGURE 8 ). Scutellum dark brown, postscutellum black, with patch of 9–10 fine, whitish lateral setae. Pleural sclerites uniformly black, shining. Post-pronotal lobe with ca. 45 fine whitish setae. Anepisternum with patch of 20 fine whitish setae on dorsal lobe, anepimeron with small patch of 16 fine whitish setae on posterodorsal portion.

Legs. ( Fig. 9 View FIGURE 9 A–C). Coxae black, setose; forefemur with distal half yellow, basally dark brown; midfemur yellow, except for basal dark brown ring; hind femur dark brown; fore and mid tibia yellow, and hind tibia darker. Tarsi darker; tibiae and tarsi with dense black pilosity; all legs with setulae irregularly arranged; tibiae densely covered with irregular rows of setae; tibiae and tarsi with stiff, stout, black setae. Apical comb of seven setae present at inner face of hind tibia; tibial spurs 1:2:1. Tarsal claws black.

Wing ( Fig. 8C View FIGURE 8 ). Membrane mostly translucent, with veins dark brown, radial veins darker, membrane brownish around r-m, m-m, and m-cu, and on basal fifth of cell sc. Length, 4.8 mm; width, 1.8 mm. Membrane irregularly covered by microtrichia. C extending past R 5 at least 1/3 of distance to M 1. R 1 and R 2+3 meeting C very close together. Dark stigma covering 3/4 of R 2+3. R 5 ending before wing tip. Cross-vein r-m short, connecting to just before mid of discal cell. M 1, M 2 and M 3 arising distally from discal cell, m-cu oblique. CuA distal half sinuous. CuP complete, A incomplete. C, Sc, radials, base of M and CuA with macrotrichia. Sc complete; R 1 long, extending about 3/4 of wing length. Haltere pale brown, pedicel and capitulum covered with short setae.

Abdomen. Tergites and sternites dark brown.

Male terminalia ( Figs. 5 View FIGURE 5 D–E, 6H–J). Dark brown. Gonocoxites with patch of large setae; gonostylus ( Fig. 6I View FIGURE 6 ) with two elongated, thin setae subapically, one inserted subbasally on the strongly sclerotized spine, the distal portion of which is abruptly curved inwards; aedeagal guide with basal apodeme ( Fig. 6H View FIGURE 6 ), midportion enlarged, tapering, distal portion with a pair of long setae directed anterolaterally and 4 short, coarse spines, apex with a short pair of coarse spine directed ventrally; sternite 10 ( Fig. 6J View FIGURE 6 ) complex, with two pairs of elongated slender arms connected basally, midportion curved, inner arms with apical spine, outer arms with a group of long, curved setae; cerci setose ( Fig. 5E View FIGURE 5 ).

Female. Unknown.

Bionomics. The specimen was collected in semi-deciduous medium dry forest with CDC trap in the natural reserve “Puuc” ( Navarrete-Carballo 2017).

Distribution. Mexico (Yucatan). Fig. 10 View FIGURE 10 .

Etymology. This species is named after “Puuc”, as the name of the type locality, used in apposition.
