03C387E074385419FC87FBCEFAA8F919.taxon	discussion	COMPARISON Free Sc is present as well in L. brasiliensis Edwards, 1932, L. barrettoi Lane, 1947, L. sanctaecatherinae Thompson, 1975, and L. cerqueirai Lane, 1958. However, the first three species have wings completely hyaline, without infuscation, and also differ from L. maculipennis n. sp. in the pattern of abdominal markings. L. cerqueirai has abdominal segments 1 - 6 with pale apical bands similar as the new species, but has a very different pattern of wing spots. In addition, L. cerqueirai has a single dorsal seta on each flagellomere, Costa extends to almost 2 / 3 of distance between R 5 and M 1, laterotergite and metepimeron are shorter than hind coxa, and M 1 and CuA are conspicuously bent anteriorly and sinusoid. REMARK Specimen NMS- 10003793 is darker, with thorax and coxae completely dark brown except for extreme tip of fore coxa; abdominal segment 6 has a slightly lighter coloration than the rest of the segment, but the genitalia are of the same structure as the other specimens included in the type series.	en	Blagoderov, Vladimir, Pollet, Marc (2020): Diversity of Lygistorrhina (Probolaeus) Williston, 1896 (Diptera: Keroplatidae, Lygistorrhininae) of Mitaraka (French Guiana), with descriptions of three new species.

03C387E074355411FCAEFA89FE55FEE4.taxon	discussion	REMARK The species was described by F. W. Edwards based on a series of 8 specimens (7 males and one female), collected by H. Scott (Cambridge, UK). While the original paper specifies that the type was presented to the British Museum (now Natural History Museum, NHMUK, London), one male and one female specimen were located in this collection. Five male specimens were deposited in the collection of the Museum of Zoology, Cambridge University (UK). Edwards did not specify the gender of the type specimens deposited in the NHMUK, so the entire type series should be considered as syntypes. Discovery of additional syntypes allows us to emend Edward’s description (only additional or misinterpreted characters being mentioned).	en	Blagoderov, Vladimir, Pollet, Marc (2020): Diversity of Lygistorrhina (Probolaeus) Williston, 1896 (Diptera: Keroplatidae, Lygistorrhininae) of Mitaraka (French Guiana), with descriptions of three new species.

03C387E074315411FF38FE2CFB0DFDCD.taxon	discussion	REMARK Lane (1947) described a female of Lygistorrhina, believing it to be a specimen of Aphanizophleps coxata Enderlein. However, the species described by Enderlein belongs to Manota. The name was treated as available by Papavero (1978), though it is a clear case of misidentification and was ignored subsequently (Oliveira & Amorim 2012). Examination of Lane’s specimens in MZUSP by the senior author revealed that they were identical to Lygistorrhina barrettoi Lane, 1947, except for being slightly darker.	en	Blagoderov, Vladimir, Pollet, Marc (2020): Diversity of Lygistorrhina (Probolaeus) Williston, 1896 (Diptera: Keroplatidae, Lygistorrhininae) of Mitaraka (French Guiana), with descriptions of three new species.
