Fig. 1 , 30-32

Description. Male. Black, mostly white tomentose, white setose. Body, 13.1 mm; wing 11.8 mm. Head: Mystax white, 1 black bristle dorsally; frons at ocellar tubercle only slightly wider than vertex. Face at antennae 4/5 as wide as one eye. Palpi white setose, only 1-2 black setae apically. Antennae and frons mostly black setose, scape and frons with sparse white setae. Ocellar setae longer than 3 antennal segments combined; 4-5 black Figure 27-29. Male terminalia of Efferia haloesa postocular bristles dorsally. (Walker), lateral views; 27. intact terminalia; 28.

gonostylus; 29. phallus with aedeagus, aedeagal tubes,

Thorax: Mostly golden yellow tomentose dor-

and phallic flange. sally, prescutellum yellowish-gray. Pronotal vestiture whitish. Scutal setae and bristles black, anterior setae about as long as scape; dorsocentrals mostly thin, slightly shorter than lateral bristles. Scutellum gray tomentose, setae whitish, as long as scape and pedicel combined, 2 stout marginal bristles, 1white, 1 black. Pleura yellowish-gray anteriorly, more grayish posteriorly, white setose.

Wing: Slightly yellowish, costal cell brown medially; costal margin almost straight, swollen or very

weakly dilated. Crossvein r-m beyond apical 1/3 of cell d. Vein R 4 angular, well beyond apex of cell d; recurrent vein shorter than cell r 4 base.

Legs: Vestiture mostly whitish, narrow apex of femora black setose, bristles black; metathoracic

femora with 7 black anteroventral bristles. Tibiae brownish-yellow, bristles black, dense setae reddish. Tarsi blackish-red with black setae and bristles.

Abdomen: mostly gray tomentose, whitish or pale yellowish setose, long on basal 3 segments, erect on

1-3; tergites 2-4 mostly brown tomentose dorsally, blackish setose medially on 2 and most of 3-4; segment 5 mostly and segments 6-7 entirely white tomentose, tergite 5 dorsally with small brown triangular spot basally; segment 8 black, brown setae, setae especially long along apical margin of sternite 8.

Terminalia (Fig. 30-32): Black, mostly black setose. Epandrium narrow, tapered apically, apex about

1/3 its middle width, dorsal process somewhat squared posteriorly with minute projections more anteriorly; 3 times longer than wide. Gonostylus slightly angular apically, with minute setulae. Phallus stout, flanges only slightly produced, aedeagal tubes oblique, about 60 degrees. Gonocoxite abruptly narrowed at basal 1/3, blade-like with width on apical 3/4 more or less uniform, apex round; setae long, moderately dense.

Female. Unknown.

Type. CUBA: Rio Seco / San Carlos Est. ~ Guantánamo [province] Cuba / 4.vii.1915, CT Ramsden ~ id.error, Erax portoricensis Hine ~ SW Bromley Coll. (holotype m, USNM) .

Etymology. The species name, hinei , genitive case, is in recognition of the significant contributions of the American dipterist J. H. Hine.

Distribution ( Fig. 1 ). Cuba, Guantánamo province; July.

Remark. Bromley (1929) mistakenly reported Ef. hinei as Erax [= Efferia ] portoricensis Hine , a Puerto Rican species. It is distinguished from Ef. portoricensis and Cuban congeners by the mostly white face and palpi, the 2 stout marginal scutellar bristles, the 3 white tomentose abdominal segments, and the combined characters of the male terminalia (Fig. 30-32).
