Diagnosis

Dohrniphora dispar is recognized by the orange, enlarged flagellomere 1 ( Figures 21, 22 ) and the unusually broad and darkened fore tarsomere 5 ( Figure 19 ). The distinct dark, circular carina on the posterior face of the hind femur, posterior to a group of approximately 60 ventrobasal peg-like setae also help distinguish it from other species ( Figures 3, 4 ).

Description

Male. Mean body length 2.33 mm; range 1.97–2.81 mm. Mean frontal ratio 0.46; range 0.42–0.48. Frons brown. Ventral fronto-orbital setae at approximately same level as ventral interfrontal setae. Flagellomere 1 orange, enlarged, approximately one-half length of eye ( Figures 21, 22 ). Palpus orange, with five apical setae. Scutum and pleuron yellow. Scutellum brown, sometimes yellow, with two pairs of scutellar setae. Posterior pair approximately 3.5 times length and thickness of anterior pair. Mean wing length 2.30 mm; range 2.19–2.62 mm. Mean costal length 0.49 wing length; range 0.47–0.52. Mean costal sector ratio 10.47:2.22:1.00; range 7.50–12.50:1.57–2.50:1.00. Halter yellow. Legs, including coxae, yellow. Fore tarsomere 5 dark brown to black, broadening towards apex, with medial, apical point; pulvilli enlarged ( Figure 19 ). Postcoxal lobes not developed. Posterior face of hind femur ( Figures 3, 4 ) with dark, ventral circular carina surrounding concavity, apical to group of approximately 60 basal, apically-rounded, curve-tipped, peg-like setae. Hind tibia without isolated setae. Abdominal tergites with yellow anterior and posterior margins, yellow medially, dark brown laterally. Venter of abdomen white to yellow. Mean cercus length 0.27 mm; range 0.23–0.30 mm ( Figures 25, 26 ).

Distribution
