(1946 p. 68) rest on the assumption that Lutz’ 1909c names 
were invalidly published. See introductory discussion above. 
Dyspangonia 1905, p. 22. defined and with fuscipennis Wied., clari 
n. sp., fasciata Macq., lugubris Macq., ferruginea Macq. 1909b 
p. 625—Esenbeckia Rond. Type Pangonia fuscipennis Wied. 
1828 (Bequaert 1924). 
Epipsila 1909b, p. 648 with eriomera Macq. and eriomeroides n. sp. 
descr. Type E. eriomeroides Lutz (Enderlein 1925). 
Himantostylus 1913a, p. 183, defined and with intermedius n. sp. 
descr. Monotypic (not Himanthostylus Borgm. 1933). 
Ionopsis 1909c, p. 28 with nitens n. gen. (sic) and Foetterlei n. sp. 
1909b, p. 650 defined and with nitens Bigot and Foetterlei n. sp. 
described ( Ionopis ). The spelling will depend on which of 
these publications appeared first. Neave’s Nomenclator gives 
Ionopis, while Borgmeier (1933) maintains that Ionopsis was 
the original spelling. Type nitens Bigot 1892 (Enderlein 
1925). The type species was originally included in Bombylopsis 
Lutz 1909a (q.v.) which has some months priority. 
Katachlorops 1909c, p. 29, with fuscipennis Macq., rufesceus Fab. 
intereuns Walk., capreolus Wied. and bitinctus Walk. 1911a, 
p. 34. with same species. 1913b, defined in key only ( Cathach - 
lorops, Gatachlorops ) Type. Dichelacera fuscipennis Macq. 
1847 (Bequaert 1924). The emended spelling Catachlorops, 
has largely prevailed. 
Laphriomyia 1911b, p. 70. defined and with mirabilis n. sp. descr. 
The erroneous variant Laphriopsis appears on p. 71. 1911a 
p. 34 ( Laphromyia ) Monotypic for L. mirabilis Lutz 1911. 
Leptotabanus 1914a, p. 72, with nigrovenosus Lutz in list of Tab- 
anidae from Xerem. 1918, in list only, no authority. 1921, in 
list only, no authority. The species seems never to have been 
described, though it is possible that Melanotabanus fuliginosus 
Lutz and Neiva (q.v.) was based on the same specimen. It is 
described in the same paper from a single specimen from 
Xerem, Rio de Janeiro, and the authors state in the paragraph 
preceding their list of Tabanidae from Xerem that the list in- 
cludes a new species based on one specimen from Xerem. 
Leptotabanus nigrovenosus is the only new species in this list. 
Since the name is invalid, a nomen nudum, as listed by Neave, 
it does not preoccupy Leptotabanus Krober 1931 as believed
