( Figures 13–16, 29, 30) Diagnosis Dohrniphora seriata, D. sexspinosa new species, and D. scutellarisBorgmeierare the only known New World Dohrniphoraspecieswith six scutellar setae. All three species key to D. scutellarisin Borgmeier’s 1960key. We did not examine any specimens of D. scutellaris, but based on the information in the description (including figures), it differs from the Caribbean species in having approximately 14 scattered ventrobasal peg-like setae. There are only four or five ventrobasal peg-like setae on D. seriata( Figures 13–16), arranged in a relatively straight row, and the six ventrobasal peg-like setae in D. sexspinosaare closely grouped ( Figures 17, 18), not in a row (as in D. seriata) nor scattered (as in D. scutellaris). Description Male.Mean body length 1.95 mm; range 1.41–2.50 mm. Mean frontal ratio 0.52; range 0.50–0.54. Frons brown. Ventral fronto-orbital setae at approximately same level as ventral interfrontal setae. Flagellomere 1 orange to brown. Palpus yellow, with five apical setae. Thorax yellow. Scutellum with three pairs of setae; middle pair approximately 3.5 times length and thickness of anterior and posterior pairs; anterior and posterior pairs subequal. Mean wing length 1.83 mm; range 1.44–2.09 mm. Mean costal length 0.51 wing length; range 0.49–0.54. Mean costal sector ratio 7.50:2.18:1.00; range 6.50–9.50:1.83–3.25:1.00. Halter white. Legs yellow. Apex of hind femur dark, although in some specimens only faintly. Postcoxal lobes not developed. Posterior face of hind femur with relatively straight ventrobasal row of four or five peg-like setae ( Figures 15, 16); some specimens with one or two setae ventral or dorsal to rest of setae in the row, not in a straight line ( Figures 13, 14). Posterior face of hind femur also with basal tooth near trochanter and three or four small, thin setae dorsal to and slightly apical of ventral row of setae. Hind tibia without isolated setae. Abdominal tergites mostly dark brown, yellow medially. Venter of abdomen yellow. Mean cercus length 0.26 mm; range 0.19–0.30 mm( Figures 29, 30). Figures 13–18. Posterior face of hind femur.

Etymology From the Latin word series, meaning row, referring to the ventrobasal row of setae on the posterior face of the hind femur. Holotype: „.
