Eiseman, Charles S., Lonsdale, Owen & Feldman, Tracy S., 2019, Nine new species of Agromyzidae from North Carolina, USA, with new host and distribution records for additional species, Zootaxa 4571 (3), pp. 301-333 : 307-308

Calycomyza novascotiensis Spencer

( Figs. 35–36 )

Material examined. NORTH CAROLINA: Durham Co., Durham , 15.vi.2015, em. by 6.vii.2015, T.S. Feldman, ex Scutellaria integrifolia , # CSE1681 , CNC564726 (1♂) .

Host. * Lamiaceae : Scutellaria integrifolia L.

Leaf mine. ( Figs. 35–36 ) A gradually widening, serpentine track, expanding to a blotch that may obliterate the earlier portion; whitish, largely discolored brown; frass in scattered grains (more closely spaced in the earlier portion).

Puparium. Yellowish-brown to brown; formed outside the mine.

Distribution. * USA: NC; Canada: NS ( Spencer 1969).

Comments. Scutellaria is a new host genus for Calycomyza and for any North American agromyzid. Since S. integrifolia does not occur in Nova Scotia, this fly must have another host. Scutellaria galericulata L. and S.

lateriflora L. are the only congeners recorded from Nova Scotia ( USDA, NRCS 2018), and we have never found agromyzid mines on either of these plants.
