Machadagrion garbei (Santos, 1961) was only known by the male holotype from Vila Nova, Bahia state, Brazil, and one male from Junqueira, Alagoas state, Brazil, collected in 1963. Over 50 years of its original description we report its rediscovery with specimens collected in Barra do Jacuípe, Camaçari County, Bahia state, Brazil, and Serra de Itabaiana, Sergipe state, Brazil. We provide illustrations and diagnosis from both sexes, including the description of the female.

Measurements. FW: 20.5; HW: 19.5; AL: 38.9; TL: 46.7. Differential diagnosis. Unfortunately, we could not perform a comparison of our specimens of M. garbei with the type material, as it was lost in the big fire of 2018 at the National Museum of the Federal University of Rio de Janeiro. However, we had access to a bona fide specimen of this taxon, housed at FAAL, collected in 2006 and compared with the original series. Machadagrion garbei (Figures 1 a−b) is a species morphologically close to M. cyanostigma (Machado, 2012) and M. dardanoi (Santos, 1968) according to male hind lobe of prothorax and cercus (Figures 3 a−d) and female hind lobe of prothorax (Figures 2 a−b). In M. garbei, the ventral “C”-shaped branch (Fig. 3c) is subequal to dorsal branch (longer than dorsal branch in M. dardanoi see Lencioni 2022); the dorsal branch of cercus in M. garbei (Fig. 3c) is similar to M. cyanostigma, but is truncated in the latter (see Lencioni 2022). Additionally, M. cyanostigma is the only species with a blue pterostigma (Machado 2012), thus it can be easily separated from other congeners. The female of M. garbei differs from those Machadagrion females by the following combination of characters (other species on parenthesis): abdomen length> 38 mm (22 mm in M. dardanoi; 31 mm in M. cyanostigma), hind lobe of prothorax (Figures 2 a−b) widest at base, with slight lateral projections, slight medial concavity, and roughly trapezoidal shape (narrower at base on M. dardanoi; roughly trapezoidal, no medial concavity, and without lateral projections on M. cyanostigma). Final remarks. The IUCN red list assessors had classified M. garbei as Data Deficient, and stated: “This poorly known species was collected for the last time in 1963 (Costa & Garrison 2001). Nothing else is known about distribution and ecology” (Vilela & Guillermo-Ferreira 2021). Unfortunately, the lack of distributional data for M. garbei is not an exception for Odonata species, as it is the case for 28% of all the assessed taxa (IUCN 2021). Until now, M. garbei was known to occur in the states of Bahia and Alagoas (Costa & Garrison 2001), and in the present study we expand its record to Sergipe state, which is located between the two states mentioned before (Figure 4). Even if the distribution of M. garbei falls within the expected range of occurrence of the species, our discovery proves that the species is still thriving on their natural habitats, including a protected area. Thus, we expect that the rediscovery of this poorly known species to be an essential step to establish strategies for its protection., Published as part of Vilela, Diogo Silva, Lencioni, Frederico Augusto De Atayde, Furieri, Karina Schmidt & Santos, Jean Carlos, 2022, The rediscovery of Machadagrion garbei (Santos, 1961) (Odonata: Coenagrionidae) with notes on the hitherto unknown female, pp. 391-396 in Zootaxa 5124 (3) on pages 392-394, DOI: 10.11646/zootaxa.5124.3.8, http://zenodo.org/record/6411030, {"references":["Santos, N.

No. of bitstreams: 0 Previous issue date: 2021-11-16 A new species of Leptagrion Selys, 1876 is described and named in honor to Dr. Jerome Constant: Leptagrion jeromei (Holotype: Brazil: Bahia, Jussari, RPPN Serra do Teimoso, Jequitiba tree (Cariniana legalis (Mart.) Kuntze, 1898) at 32 m, 10.v.2005, K.S. Furieri leg and deposited in FAAL). This species was confused for a long time with L. andromache Hagen in Selys, 1876 its closest congener. Diagnostic illustrations of L. andromache (lectotype and specimens collected at AmapBrazil) and L. jeromei spec. nov. are presented. We also present the northernmost record for L. andromache in Amap state, Northern Brazil.

In this paper, we provide taxonomic updates on the genus Leptagrion Selys: the females of L. acutum Santos and L. porrectum Selys are illustrated and diagnosed for the first time. We also add to the original description of L. acutum based on a male collected in the Atlantic Forest. A key for females is also provided for the currently known species of Southeast of Brazil.
