( Figs. 18, 21 , 120 , 273–278 ) Holotype . VERMONT : Chittenden Co. , Essex , Woodside Park , 29.vi.2014 , em. 15.vii.2014 , C.S. Eiseman , ex Helianthus , #CSE1184, CNC384849 ( 1♂ ) . Etymology. This species is named in honor of Hubert W. "Hub" Vogelmann ( 1928–2013 ), educator, conservationist, and founder of the University of Vermont's Field Naturalist graduate program, who gave enthusiastic encouragement as CSE embarked on his study of leafminers. Host. Asteraceae : Helianthus decapetalus L. Leaf mine. ( Fig. 120 ) The single mine found was a whitish, upper surface blotch, formed in the angle between the midrib and a lateral vein, near the base of the leaf. The brown, liquidy frass line was largely deposited in transverse arcs. Puparium. ( Fig. 21 ) Reddish-brown, formed outside the mine. Distribution. USA : VT. We have found identical leaf mines on Helianthus decapetalus in New York . Adult description. Wing length approximately 2.6mm ( ♂ ). Female unknown. Length of ultimate section of vein CuA1 divided by penultimate section: 2.5. Eye height divided by gena height: 7.7. First flagellomere rounded. Arista pubescent. Cheek narrow, well delimited. Notum subshining. Chaetotaxy : Two ors, two ori (thinner); setae decreasing in length anteriorly. Postvertical and ocellar setae subequal in length to anterior ori, ocellar thinner. Three dorsocentral setae; posterior two strong (evident from sockets, with only right second seta remaining), anterior third seta thinner, less than half length of second seta, to which it is closely set. Six rows of acrostichal setulae. Mid tibia with one lateromedial seta. Coloration : ( Fig. 18 ) Setae black. Head light yellow; antenna, back of head, ocellar tubercle, posterolateral corner of frons to base of inner vertical seta, clypeus and palpus black. Thorax black to dark brown; complete light yellow stripe along scutum and postpronotum (excluding large spot on postpronotum); dorsal margin of anepisternum with light yellow stripe that is very narrow anteriorly and 1/3 height of sclerite posteriorly. Calypter margin yellow, hairs dark brown. Haltere white. Abdomen and legs black, light yellow with spot on apex of fore femur as long as wide, and base of fore tibia yellowish. Genitalia : ( Figs. 273–278 ) External genitalia of Calycomyza type . Phallophorus narrowed apically. Basiphallus a single dorsal sclerite that narrows to base and is broader and irregular apically, with right margin slightly longer. Hypophallus large and membranous with medial tubule and one pair of apically tapering lateromedial sclerotized plates. Paraphallus membranous, carinate, semicircular in profile, lightly sclerotized with small irregular darker streak medially. Mesophallus with subbasal attachment of minutely annulated duct, with insertion hidden behind inverted V-shaped ventrobasal plate; base rounded, widest apically, width slightly more than ¼ length in profile, nearly 1/3 length viewed ventrally. Distiphallus very dark, straight, angled ventrally, nearly as long as mesophallus, widest as base, swollen medially, slightly flattened laterally at narrow rounded apex. Ejaculatory apodeme with broad stem that is nearly as wide as base, blade pale with marginal striations; sperm pump with sclerotization around insertion of duct. Comments. Using Spencer & Steyskal (1986) , this species will key to Calycomyza frickiana Spencer , which is said to make a large, greenish blotch mine on Bidens , Helianthus , and Rudbeckia ( Spencer & Steyskal (1986) did not describe the frass, but their illustration shows frass in scattered, irregular lumps). The male genitalia of the new species differs, however, in that the hypophallus is larger with a wider ( Figs. 277, 278 ), weaker pair of sclerites positioned medially, the paraphallus is strongly semicircular with a weak sclerotized patch, and the distiphallus is much longer.
