Tetragoneura marceda The Megophthalmidia (Diptera, Mycetophilidae) of North America including eight new species Kerr, Peter H. ZooKeys 2014 386 29 83 9HZKN http://species-id.net/wiki/Ectrepesthoneura_marceda Sherman, 1921 Sherman 1921 Insecta Mycetophilidae Ectrepesthoneura CoL Animalia Ectrepesthoneura marceda Diptera 38 67 Arthropoda species marceda   Tetragoneura marcedaSherman, 1921: 20  Examined material. Although the original description states that 35 specimens were examined, the syntype series currently consists of 22 specimens labeled as "Tetragoneura marceda Sherman, 1921" within the CNC collection. One specimen is a female  Mycetophilasp. (specimen # 765). As an additional note, it appears that C.B. Garrett added type labels and notes on Sherman'slabels (e.g., "R.2.3. absent, ♂"). Specimens # 600 and # 324 have vein R4 present on the right wing. E.I. Coher dissected one specimen (specimen # 473) and labeled it as the holotype. As first reviser and in the interests of stable taxonomy, I designate this specimen as the lectotype. Lectotype: ♂, "Savary Id., 10.4.17 [on mount] / 473 [on back side of mount]/ R.2.3 ABSENT, ♂, Tetragoneura marceda R.S. Sherman, ♂ / TYPE, See letter [handwritten], C.B.D. Garrett / HOLOTYPE, Megophtalmidia [sic] marceda, (Sherman) 1921 ["(Sherman) 1921" on underside; handwritten label created by E.I.
