M. cappilicrus Pucci new species

Figures 27–31

Etymology: Latin; in reference to the setae of the hind tibia and tarsi being especially thick.

Females.—Color: Face and below usually pale yellow (occasionally light brown), the rest of the head orange to light brown but dark brown to black near the ocelli and the flagellum brown to dark brown; mesosoma orange or brown with darker areas dorsally or mesosoma completely black; legs mostly orange to brown, hind tibia and tarsi brown to black—darker than fore and mid legs; metasoma black, brown, orange to pale yellow, the petiole darker than the remaining terga and the sternum lighter than the terga. Length excluding ovipositor: approximately 3.5. Head: Occipital carina widely absent medially; lateral eye/gena 1.2–1.5; transverse head/face 2.3–2.5; flagellum length 3.2–3.4, number of flagellomeres 27–28; first flagellomere/second 1.3–1.4; face smooth but for setal insertions; clypeus suboval to subtriangular; length of last four maxillary palpomeres/fore femur length 0.80–0.90. Mesosoma: Subanterior pronotum carinate, mostly smooth elsewhere; median mesonotal lobe distinctly raised anteriorly, especially laterally; number of setae along widest transverse line of anterior lobe approximately 15; notaulus broad and irregular fovea, joined throughout posterior half of mesoscutum; longitudinal carina on the posterior mesoscutum present; lateral mesonotal lobes glabrous but for a narrow fringe; C+SC+R length 1.2–1.4; stigma length/R1 1.2–1.3; fore wing RS a shallow arch, rather straight distally; sternaulus formed by rather wide and irregular fovea, extending horizontally or restricted to mid mesopleuron; propodeum areolate-rugose, areola present dorsally, median groove rather wide; outline of propodeum in lateral view with posterior end vertical; hind tibia and tarsi with setae distinctly thicker than those on fore and mid legs; setae of hind femur less than half maximum femur width; hind tibia subequal to or less than C+SC+R. Metasoma: Petiole smooth but for medial protuberance that narrows posteriorly and subbasal petiole depressed laterally forming ridges dorso-laterally; petiole length/posterior width 2.1–2.2; terga 2 + 3 length 0.56–0.66; sheath length 0.93–1.0, sheath/C+SC+R 0.68– 0.81.

Males differ from females by the following: length usually 2.7–3.3, C+SC+R 1.0–1.1; transverse head/face 2.0–2.1.

Specimens examined: Holotype: female, Mexico, Durango , 6 mi. E of Durango, VII.14.1964, W. R . M. Mason ( CNC). Paratypes: Brazil: 1 male, Parana Maringa , V . 13.1961, N. Marston-3 ( KSUC). Costa Rica: 1 male, Heredia, Est. Biol. La Selva , 50–150 m, 10.26N 84.01W, II-IV . 1993, P. Hanson, huertos, Malaise trap, set by G. Wright ( ESUW); 1 male, Monte Verde, T-B, I.24–26.1972, M.M. Powel ( UCDC); 1 female, Guanacaste, Santa Rosa National Park , 300m, ex. Malaise trap, Site # BH-11-O, IX.6–27.1986, I.D. Gauld & D. Janzen, Bosque Humedo, mature evergreen dry forest, in clearing, fully isolated part of day ( ESUW); 1 female, as above but Site # SE-6-C, VIII . 3–24.1985, Bosque San Emillo, 50 yr old deciduous forest, more or less fully shaded as possible ( ESUW). El Salvador: 2 males, Quezaltepeque , 500m, VI . 19.1963, D.Q. Cavagnaro & M.E. Irwin ( CAS). Mexico: 4 males, Durango, 6 miles south of Durango, 6100’, VII.5.1964, W. R . M. Mason ( CNC); 1 male, Veracruz, Fortin De Las Flores, Sumidero, Planta De La Cerveceria , 1 NG., Daniel Rabago Res., elev. 2500–3000’, H. V . Weems Jr., V . 20–23.1965, Malaise trap ( FSCA); 1 female, Cordoba, Crawford [assumed to be from Mexico because similar labels have other Mexican towns] ( USNM). Paraguay: 1 male, Italpúa Pirapó , 26°51’S 55°32’W, 122m, I.1–3.1972, L. Peña ( CNC). Peru: 1 female, Junin, 22 km W San Ramon, 10°59.35’S 75°25.5’W, 1220m, XI.24–27.2007, D. Brzoska, FIT ( CNC) .

Flight period: Apparently year-round.

Remarks: A male paratype from Costa Rica is unusually large (length ~4.0 mm) and has vein (RS+M)a (ESUW). Four specimens of two morphospecies housed at ESUW and CAS are close to M. cappilicrus . In particular, they have thickened setae of the hind tibia and tarsi but differ in various other characteristics.
