The number and pattern of peg-like setae vary, although there are usually two rows along the ventral margin, in addition to a larger group of setae dorsal to the row (sometimes in a curved or triangular pattern) ( Figures 5–12). We examined the holotypefemale of  Dohrniphora cavifemurBorgmeierand found it to be a probable female of  D. divaricata. Although taxonomy of  Dohrniphorais based on males, the number of tergal plates and colour of the mid coxa allowed us to match it with other Caribbean specimens of  D. divaricata. The distortion of the hind femur, given by Borgmeier as the main character of this species, is an artifact of preparation (see Diagnosis section of  D. cornuta).  Description  Male.Mean body length 2.09 mm; range 1.66–2.50 mm. Mean frontal ratio 0.51; range 0.47–0.54. Frons brown to dark brown. Ventral fronto-orbital setae at approximately same level as ventral interfrontal setae. Flagellomere 1 brown. Palpus orange, with five apical setae. Scutum and dorsal half of pleuron light brown to brown. Ventral half of pleuron white. Scutellum dark brown. Two pairs of scutellar setae present; posterior pair twice length and thickness of anterior pair. Mean wing length 1.92 mm; range 1.50–2.25 mm. Mean costal length 0.51 wing length; range 0.48–0.54. Mean costal sector ratio 9.50:2.24:1.00; range 7.00–11.33:1.67–2.40:1.00. Halter white. Legs mostly light brown; fore and hind coxae white, mid coxa dark brown. Postcoxal lobes well developed, yellow. Posterior face of hind femur ( Figures 5–12) with large triangular group of basal peg-like setae; number of setae varies, but usually with two rows along ventral margin of femur and several more dorsal peg-like setae (see further discussion in Variation, below); also with shallow round depression posterior to setae. Hind tibia without isolated setae. Abdominal tergites dark brown, yellow medially. Venter of abdomen white. Mean cercus length 0.26 mm; range 0.20–0.30 mm( Figures 27, 28).  Variation  The variation in the setae of the posterior face of the hind femur is extensive. Specimens from the typelocality in Saint Vincent have the largest number of setae ( Figures 5, 6), and are similar to mainland specimens we have seen (for example from Costa Rica). Samplingis insufficient to determine if this variation has a strong geographical component, and whether certain patterns are restricted to individual islands. Someof the variants are shown here ( Figures 5–12).  Distribution  Argentina, Brazil, Costa Rica, Trinidad, West Indies.  Material examined   Dominica: Cabrit Swamp, 1 „, 23 February 1965, W.
