( Figures 17, 18, 31, 32) Diagnosis Dohrniphora sexspinosais easily distinguished from other Dohrniphoraspeciesby its six scutellar setae, and close group of six ventrobasal peg-like setae. D. sexspinosakeys to D. scutellarisin Borgmeier’s 1960key because of the presence of six scutellar setae, but the arrangement and number of the ventrobasal peg-like setae on the hind femur differs. (See Diagnosis section of D. seriata.) Description Male.Mean body length 2.44 mm; range 2.12–2.72 mm. Mean frontal ratio 0.50; range 0.48–0.51. Frons and flagellomere 1 orange to brown. Ventral fronto-orbital setae at approximately same level as ventral interfrontal setae. Palpus yellow, with four or five apical setae. Scutum and scutellum light brown. Scutellum with three pairs of scutellar setae. Middle pair approximately 2.5 times length and thickness of other pairs. Anterior and posterior pairs about equal in size. Pleuron yellow. Mean wing length 2.22 mm; range 2.00– 2.41 mm. Mean costal length 0.52 wing length; range 0.49–0.53. Mean costal sector ratio 8.54:3.11:1.00; range 7.67–10.75:2.67–3.75:1.00. Halter white. Legs mostly yellow, except apex of hind femur dark brown, almost black, on anterior and posterior faces. Postcoxal lobes present; yellow, rounded. Posterior face of hind femur ( Figures 17, 18) with a group of six peg-like setae at base of ventral margin, basal tooth, and apical tooth, dorsoapical to the group of setae (teeth difficult to see under light microscopy). Hind tibia without isolated setae. Abdominal tergites dark brown, with or without thin yellow line medially. Venter of abdomen yellow. Mean cercus length 0.29 mm; range 0.23–33 mm( Figures 31, 32). Distribution Dominican Republic. Etymology Combination of the Latin words sexand spinosus, referring to the six setae on the posterior face of the hind femur. Figures 19, 20. Fore tarsomere 5.

1. Scutellum with four setae................. 2 – Scutellum with six setae................. 4 2. Posterior face of hind femur with sparse dorsal setae; ventrobasal region with only four or five short, thick peg-like setae ( Figures 1, 2).... D. cornuta(Bigot) – Posterior face of hind femur without dorsal setae; ventrobasal region with many (more than 20) long, thick peg-like setae............ 3 3. Flagellomere 1 orange, enlarged ( Figures 21, 22); fore tarsomere 5 dark, broad ( Figure 19); posterior face of hind femur with dark, circular ventral carina apical to ventral setae ( Figures 3, 4).......... D. dispar(Enderlein) – Flagellomere 1 brown, not enlarged; fore tarsomere 5 same colour as rest of leg, not broad ( Figure 20); posterior face of hind femur without carina, but with shallow ventral depression apical to ventral setae ( Figures 5–12)....................... D. divaricata(Aldrich) 4. Posterior face of hind femur with relatively straight ventrobasal row of four or five setae ( Figures 13–16); postcoxal lobes not developed...
