Hendelia heliconiae  spec. nov.

( Figs 4View FIGURES 1 – 5, 20–22View FIGURES 17 – 28, 32View FIGURES 29 – 32)

Description ( Fig. 4View FIGURES 1 – 5). Body length 3.4 – 4.3mm.

Male. Most bristles brown, with vibrissa brown to black. Anterior fronto-orbital half length of mid frontoorbital and posterior fronto-orbital absent. Two pairs of dorsocentral bristles with small additional bristle in front of anterior dorsocentral. One minute and one short pair of lateral scutellar bristles. Head yellow with ocellar tubercle brown and antenna (excluding arista) light yellow; frons sometimes orange to brown medially. Notum yellow with medial stripe (often broken at transverse suture) and dorsum of scutellum brown; lateral margin of scutum sometimes orange to brown. Dorsal half of pleuron orange with only thin subnotal stripe present. Legs light yellow with fore coxa white, base of hind tibia brownish and fore tarsi brown with basal 1 / 3 of first segment yellow to white. Wing infuscated on distal 1 / 3 and along R 2 + 3 at intersection of vein r-m.

Male terminalia. ( Figs 20–22View FIGURES 17 – 28) Similar to H. nigripalpus  except as follows: produced lobe on anterodistal margin of epandrium narrow and nearly half height of epandrium; all setae on surstylus short; hypandrium with only two long bristles; pregonite setulose apically and medially.

Female. Externally similar to male except as follows: antenna yellow with inner-distal margin sometimes infuscated; apex of hind tibia and femur brown; notal stripe not broken at suture.

Female terminalia. ( Fig. 32View FIGURES 29 – 32) Similar to terminalia of H. boliviensis  except ventral receptacle approximately as long as spermathecal duct and spermatheca shorter.

Etymology. The specific epithet refers to the Heliconia  plant upon which the holotype was taken.

Distribution. Bolivia, Costa Rica, Ecuador.

Cartago: Tapanti N.P., nr W entrance, 1150m, sweeps, trail to hydro tower/creek, 11.x. 1999, Marshall & Buck (1 Ψ, DEBU), Turrialba, Tayutic, Estacion Grando do Oro, 1200m, i. 1994, Malaise, P.

Marshall, 1200m, on leaves, small dung bait, 27.x. 1999 (2 Ψ, QZAC), river trail, 27.x. 1999 (2 ɗ, QZAC), river trail, 29.x. 1999 (2 ɗ, DEBU), river trail, 1200m, sweep, 29.x. 1999 (1 ɗ, QZAC), river trail, 1200m, sweeping, 29.x. 1999 (3 ɗ 1 Ψ, DEBU; 1 ɗ, QZAC), main trail, 1400 – 1600m, 0° 7 ’ 34 N, 78 ° 37 ’ 57 W, 27.iv. 2002 (2 Ψ, DEBU).

Comments. Both sexes of Hendelia heliconiae  can be distinguished from other neotropical Hendelia  by having fore tarsi that are dark brown with the base of the first segment yellow. The closely related H. boliviensis  has similar female genitalia, but the dark markings on the palpus and antenna clearly identify it.
