Coniceromyia hoggi new species

( Figs. 2 , 7–8 , 14 , 24 ; Morphbank images 477861, 477862, 477864)

Recognition. C. hoggi is most easily recognized by its distinctive wing pattern, with the darkening at the apex of the radial cells, apical one-half of membrane anterior to M2, apical one-fifth of membrane between M2 and CuA1, and the presence of a lighter brown elongate macula between CuA1 and A1+CuA2.

C. hoggi keys to couplet 6 in the key to patterned-wing species ( Kung & Brown 2000a). Unlike C. blomae Peterson & Arntfield , the darkening of the wing of C. hoggi does extend to the apical margin and the darkening is much less extensive. Wing vein M1 is not thickened in C. hoggi , and veins M1 and M2 are not divergent in apical two-thirds, distinguishing this species from C. apicalis Kung & Brown , in addition to the different wing patterns.

Description. Body length 2.56 mm. Frons dark brown. Frontal height 1.17 frontal width. Flagellomere 1 brown, pyriform. Palpus light brown. Scutum, scutellum, and pleuron brown. Anepisternal setae present. Legs mostly yellow, except mid- and hind coxae light brown. Foretibia with 2 anterodorsal setae. Foretarsomere 1 anteriorly excavate, with long basal seta, and long, thin, setose anteroapical projection ( Fig. 2 ). Foretarsus slender, with tarsomeres approximately twice as long as wide. Tarsal ratio 2.33:2.00:2.00:2.00:1.50. Posterior face of hind femur with narrow band of tiny, blunt posterior setae on basal half; setae arranged broadly basally, tapering apically ( Figs. 7–8 ). Hind tibia with one long dorsal seta. Costa not thickened ( Fig. 14 ). Wing vein R2+3 absent. Wing with extreme apex of costal cell and apical two-fifths of cell r1 darkened by pigment. Apical one-half of wing membrane between anterior margin and M2 darkened, apical one-fifth of membrane between M2 and CuA1 darkened. Wing veins M1 and M2 parallel in basal two-fifths, sinuous and divergent apically. CuA1 relatively straight. M2 and CuA1 more widely-spaced than M1 and M2; CuA1 and M2 parallel in basal two-thirds, M2 rounded anteriorly in apical one-half. Costa length 0.43 wing length. Halter white. Abdominal tergites dark brown, pruinose. Venter of abdomen brown. Left surstylus of genitalia broad, turned ventrally at apex ( Fig. 24 ). Left hypandrial lobe with rounded pointed apex.

Distribution. Costa Rica.

Derivation of species name. This species is named posthumously for my mentor and friend, Norman D. Hogg.
