Fig. 53 View FIGURES 43–53

Recognition. This yellow species is similar to M. striatula   , but has a distinctive pair of dorsoapical setae on the ovipositor, and a characteristic rounded apex of the sclerite of intersegment 7–8.

Description. Female (male unknown). Body length 2.0– 2.3 mm. Frons yellow, bare of setulae; ocellar triangle black. Mean frontal width 0.47, range 0.47–0.49. Medial furrow absent. Ocular and genal setae brown. Flagellomere 1 and aristomeres 1–2 yellow; aristomere 3 brown. Palpus white; palpal setae black. Scutum yellowish­brown, except with narrow, posterolateral dark brown markings. Scutellum yellowish­brown, with anterolateral dark round spot. Pleuron yellowish­brown, except basalare black. Legs yellowish­brown. Combined length of foretarsomeres equal to length of foretibia. Foretarsal claws recurved, with large basal lobe. Mean costal length 0.54 wing length, range 0.53–0.55. Halter yellow. Abdominal tergites anteriorly yellow, posteriorly black. Ovipositor yellow at base, mostly black; curved dorsally (holotype less abruptly curved along ventral margin than in Fig. 53 View FIGURES 43–53 ), with narrow dorsal lobe projecting further posteriorly than ventral lobe; with scattered short setae, plus one pair larger, divergent setae at dorsal apex. Sclerite of intersegment 7–8 with enlarged, rounded apex.

Host. The holotype was collected attacking a worker of Trigona truculenta   , which is mounted on a point on the same pin.

Geographical distribution. Costa Rica and Peru.

Derivation of specific epithet. Greek trichos for bristle and peras for end, referring to the two strong setae at the apex of the ovipositor.
