MELALONCHA HANSONI View in CoL SP. NOV. ( FIGS 22 View Figures 22–27 , 76 View Figures 76–86 )

Recognition. This species is recognized by the four slightly enlarged setae at the apex of the ovipositor ( Fig. 76 View Figures 76–86 ).

Description. Body length 2.5–2.8 mm. Frons orange, except vertex and ocellar region, which are black. Setal base of all setae coloured like rest of frons. Mean frontal

width 0.3 head width; range 0.29–0.3. Frons with fine reticulate sculpturing, slightly shiny, punctate, with small, black setulae. Median furrow absent. Frontal setae normal; arrangement of frontal setae unmodified, with ventral interfrontal setae near venter of frons. Dorsal interfrontal setae present, 0.6 length of postocellar setae, level with ventral margin of ventral ocellus. Palpus unmodified. Ocular and genal setae flattened, yellow. Fore tarsomeres yellowish-brown, relatively narrow. Combined length of fore tarsomeres approximately 0.8 tibial length. Fore tarsomere 1 approximately twice as long as tarsomere 2. Fore tarsomere 5 slightly expanded. Pulvilli of fore leg large. Tarsal claws of all legs small, bifurcate at apex. Mid and hind leg yellowish-brown, with tarsomeres 4–5 and apex of tarsomere 3 of mid leg dark brown dorsally. Mean costal length 0.56 wing length; range 0.54–0.57. Tergite 6 of similar colour to other tergites. Tergites 2– 6 lateroventrally black, with silver pollinosity. Venter of abdomen grey. Ovipositor relatively tubular, slightly curved ventrally. In dorsal view, lateral setae of ovipositor thin, short; larger, thicker, pairs of setae dorsoapically and subapicolaterally. Ventrally, ovipositor with short, fine, sparse setae. Surface of ovipositor with faint, irregular, reticulate sculpturing.

Variation. Wing vein R 2+3 is present on the left wing of the paratype.

Geographical distribution. Costa Rica.

Etymology. Named after Dr Paul Hanson, whose Malaise trapping programme has collected many new phorid flies.
