known species from Brazil. Caribbean and Central American spe- 
cies all have the sixth antennal flagellomere strongly aristate. In this 
regard, the South American species are somewhat intermediate 
between more typical members of Nothomyia , as exemplified by the 
type-species ( N . scutellata Loew, from Cuba), and species of Myxo- 
sargus. This further indicates the need for reevaluation of generic 
concepts within the tribe.

Type material. The holotype male is housed in the Zoologisches 
Museum der Humboldt-Universitat, Berlin, East Germany. It is 
labeled: “Brasilien/9368/[purple square]/ Coll. H. Loew/Type/ 
Pseudoberis fallax Type Ender. $ Dr. Enderlein det. 1919/ Beris (Nov 
gen) eupoda m/Nothomyia fallax (Enderlein) Det. N. E. Woodley 
1982”. The specimen is in excellent condition. The genitalia are 
preserved in glycerin in a microvial attached to the pin of the 
specimen. 
Description. Male. Head (Fig. 1) black, with faint bronzy green- 
ish metallic reflections; eyes essentiallly holoptic, separated on upper 
frons by less than diameter of a single ommatidium, ommatidia not 
strongly differentiated in size; lower frons widely triangular, slightly 
convex, sharply impressed medially in lower half; upper frons very 
narrowly triangular in front of anterior ocellus; ocellar tubercle 
moderately prominent; face wide, convex, sides divergent toward 
oral margin, but not produced downward; lower occiput somewhat 
convex; lower frons with small, tear-drop shaped, silvery white 
tomentose spots near upper margins which are contiguous with eye 
margins, and with very narrow margins inconspicuously tomentose, 
head otherwise not tomentose; head mostly pilose, hairs longest on 
face where they are about as long as the basal two antennal seg- 
ments combined, mostly brownish, but whitish lateral to antennae, 
most of occipital hairs also pale; antennae subequal to head in 
length, ratio of segments 13:15: 55[7:4:5:6:7:26], first two segments 
blackish, very narrowly pale apically, with blackish hairs; flagellum 
gradually tapering to a sharp apex, first three flagellomeres yellow- 
ish brown, last three darker brownish; flagellum with velvety vesti- 
ture, but the individual hairs quite long and noticeable; palpi small,
