03E46477FF8A6B09FF04F8FA7CCFFC8E.taxon	distribution	Distribution. Brazil (Acre, Amazonas, Pará, Goiás) and Uruguay. Taxonomic discussion. Leptoconops (L.) brasiliensis is a typical member of the Leptoconops subgenus by the frons with a pair of setae, claws with a basal bristle, tarsi with strong ventral spines and female genital lamellae long. From the seven Neotropical species, it is similar to L. (L.) casali Cavalieri & Chiossone by the antennal flagellomeres shape, the aspect of the palpal sensory pit, the costa reaching 0.40 – 0.50 from total wing length and the ovoid spermathecae. These species can be easily distinguished from each other by the smaller wing length (1.24 in L. (L.) casali), the palpus with segment 3 only slightly longer than 4 (1.5 x longer in L. (L.) casali) and longitudinal veins extending to the wing margin (obsolete in L. (L.) casali). Ronderos & Spinelli (1992) and Spinelli et al. (2022) consider in their key that L. (L.) brasiliensis has bare frons; however, we observe that the specimens present a pair of medial setae in the frons (Fig. 1 A). In addition, these authors cited the flagellomere 12 of female antenna 4 – 5 times longer than broad, but herein we observe this relation much smaller. In this case, we have seen that the antenna position after slide montage and the conservation state of the material is very important and can influence this relation. Considering this, we suggest not using this measurement to separate and define species from this subgenus. In 2005, Trindade & Gorayeb corrected the record of the type locality for the state of Pará and collected this species in the estuarine coastal zone and on the coast of this same state. Pessoa et al. (2012) found it on the river margin in the state of Acre. Farias et al. (2015) collected in the Amazonas State, near small farms, but there is no data describing if it was collected in upland or lowland environments. Spinelli et al. (2005) have reported L. (L.) brasiliensis from Argentina, but recently Spinelli et al. (2023) recognized the specimen is L. (L.) casali and removed the record. We report this species for the first time in the Brazilian State of Goiás, in Uruaçú municipality, which is in the Cerrado biome. This region includes one of the largest artificial lakes associated with a hydroelectric plant in Brazil. Thus, we can observe that L. (L.) brasiliensis occurs in areas with high humidity, even if they are not coastal areas, as it was previously reported. It is the only species from this subgenus found in Brazil.	en	Santarém, Maria Clara Alves, Cremer, Marta Jussara, Vieira, Jenyffer Vierheller, Lemos, Giulia Gaglianone, Pecor, David B., Felippe-Bauer, Maria Luiza (2023): Redescription of Leptoconops (Leptoconops) brasiliensis (Lutz) and Leptoconops (Megaconops) floridensis Wirth (Diptera: Ceratopogonidae) with its first Brazilian record.

03E46477FF8F6B05FF04FCFE7BC4FD32.taxon	distribution	Distribution. United States (Florida), Jamaica (?), Colombia, Brazil (Santa Catarina). Taxonomic discussion. Leptoconops (Megaconops) floridensis Wirth is the unique species described for this subgenus worldwide. Wirth & Atchley (1973) described L. (Megaconops) based on this species and remarked that it is similar to Leptoconops (sensu stricto), but females differ in the leg and antennal proportions, claw structure and setation of the frons. In fact, we observe that in L. (M.) floridensis femora and tibiae legs are stout, the flagellomere 12 is tapered and slender distally, and the tarsal claws lack basal spines or bristles, while in the Leptoconops subgenus the femora and tibiae are slender, the flagellomere 12 is usually blunt or conical and the claws present a basal bristle. However, the frons setation is too variable in our L. (M.) floridensis specimens and we cannot differ it from other species within the L. (Leptoconops). Wirth & Atchley (1973), in their redescription, indicated that frons present four to five pairs of fine setae, despite the drawing show four setae on left and five on right side. In really, we can see the drawing pattern in the holotype specimen (Fig. 4 B), with a total of nine mesal setae. Here, we analyze more specimens, and we can see that the unequal distribution on each side is usual, with the frons presenting 2 – 9 mesal setae (Fig. 6 A). In the description of L. (M.) floridensis (Wirth 1951) and in its subsequent redescription (Wirth & Atchley 1973), the authors state that the tarsomeres are unarmed. In contrast, we observe that the tarsomeres present spines, primarily the basitarsi, but they are more hyaline and slenderer than commonly seen in other species from the genus. Also, we can see a strong subapical dorsal spine in the fore tarsomeres 3 and 4, which is a unique characteristic of this species. Considering this, we suggest that frons setation is not a good feature to identify L. (M.) floridensis and consequently the subgenus Megaconops. In addition, the mandible lacking any teeth, the fore tarsomeres 3 – 4 with a dorsal subapical spine and the spermathecae with ventral perforations are unusual characteristics and unique within all Leptoconops species and can be more accurate to identify this species. Leptoconops (M.) floridensis was described by Wirth (1951) to Santa Rosa Island, Escambia County, Florida, United States. Posteriorly Wirth & Atchley (1973) found it in Seahorse key, Levy County, and in a mangrove area in Colombia, in both places they were biting humans. The authors also describe a single male specimen from Jamaica which they presumed on general characters of size, coloration, and close similarity in external features to be L. (M.) floridensis, but they emphasize that additional collecting was necessary to prove it. Considering this, we maintain the record for Jamaica with a question mark. Herein, we found the species in the estuary and on sandy beaches, also a coastal area, in Santa Catarina, Brazil, biting birds. It is the first record of this subgenus in Brazil. As any male specimens were found, we did not add any characteristic to its first description made by Wirth & Atchley (1973).	en	Santarém, Maria Clara Alves, Cremer, Marta Jussara, Vieira, Jenyffer Vierheller, Lemos, Giulia Gaglianone, Pecor, David B., Felippe-Bauer, Maria Luiza (2023): Redescription of Leptoconops (Leptoconops) brasiliensis (Lutz) and Leptoconops (Megaconops) floridensis Wirth (Diptera: Ceratopogonidae) with its first Brazilian record.
