Ophiomyia

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 : 306

Ophiomyia sp. 2

( Figs. 6 , 32 )

Material examined. NORTH CAROLINA : Durham Co., Durham , 23.v.2017, em. 25.v.2017, T.S. Feldman, ex Pyrrhopappus carolinianus , # CSE3714 (1♀).

Host. Asteraceae : Pyrrhopappus carolinianus (Walter) DC.

Leaf mine. ( Fig. 32 ) Whitish, on the upper leaf surface; primarily over the midrib, with occasional short excursions into the blade. Although the leaf from which the adult was reared had no mining on the lower surface, TSF has found similar mines on this host with associated lower surface tracks as with Ophiomyia sp. 1.

Puparium. ( Fig. 6 ) Whitish; formed within the mine, with the anterior spiracles projecting through the upper epidermis.

Comments. Although the leaf mine seems consistent with Ophiomyia beckeri , the single reared female cannot be identified. This is the first published record of any agromyzid from Pyrrhopappus DC. M.W. Palmer (in litt.) has found Ophiomyia mines on stems of P. carolinianus in Oklahoma.
