0384E974FF8A964AFD8DFD11FD699369.taxon	discussion	Remarks The relationship between the genera Baliga and Hagenomyia is still unclear. Baliga has been assigned as a synonym of Hagenomyia in several works, including Esben-Petersen (1913), Markl (1954) and Wang et al. (2018), while Stange (2004), Hayashi et al. (2020) and Oswald (2024) considered an opposing opinion. Here, we agree with the latter view. By comparing the Taiwanese and the Japanese species in Hayashi et al. (2020), Baliga is an independent genus that can be determined by a series of characters, including female anterior gonapophyses almost as long as posterior gonapophyses, the shape of the male genitalia, especially the three-pronged mediuncus, as well as the long, slender mandible and the few abdominal digging setae of the larvae. Most species inhabit moist forest environment (Stange et al. 2003; Hayashi et al. 2020; Lin et al. 2021).	en	Lin, Yu-Hsiu Hugh, Ko, Chiun-Cheng, Tseng, Hui-Yun (2024): Taxonomic revision of the antlion tribe Myrmeleontini (Neuroptera: Myrmeleontidae) of Taiwan.

0384E974FF8B9645FDBFFCCBFC39920E.taxon	discussion	Remarks This is the largest species of Myrmeleontini in Taiwan and can be easily recognized by the large white pterostigma on the wings (Fig. 2 C). The adults are very similar to those of B. kimurai Hayashi et al., 2020 from Ishigaki Island, Japan, but with a larger pterostigma (Hayashi et al. 2020). Stange & Wang (1998) recorded this species as B. eurystictus (Gerstaecker, 1885), but in later publications, the name B. asakurae was used instead (Miller et al. 1999; Stange et al. 2003).	en	Lin, Yu-Hsiu Hugh, Ko, Chiun-Cheng, Tseng, Hui-Yun (2024): Taxonomic revision of the antlion tribe Myrmeleontini (Neuroptera: Myrmeleontidae) of Taiwan.

0384E974FF849640FE34FD6EFCF19139.taxon	discussion	Remarks This species is similar to B. asakurae in characters, including wing venation (forewing RP arising almost opposite to CuA fork, often with an extra row of cells under the hypostigmatic cell; hindwing RP arising almost opposite to MP fork, at origin runs equidistant to RA and MA), genitalia (male mediuncus three-pronged in caudal view; female anterior gonapophyses more than half length of posterior gonapophyses), and larval morphology (IX abdominal sternite without or with few reduced digging setae) (Figs 5 C, 6 A – B, 7; Lin et al. 2021: figs 3 b, 4 b, 6). Such a combination of characters can also be observed in other species of Baliga from Japan (Hayashi et al. 2020). Due to such, this species should be placed in Baliga. This species differs from B. asakurae by the smaller pterostigma and fully dark brown abdomen of the adult (Figs 1 B, 5 C). Since the original description, there have been no records of Baliga brunneipennis collected from Taiwan. During their 1998 collecting trip to the island, Stange and Miller did not collect this species and mentioned that only the holotype is known. As a result of this collecting trip, they described six new species of Myrmelon, including Myrmeleon alticola Miller & Stange, 1999 (Miller et al. 1999; Stange et al. 2003). After comparing images of the holotypes of each nominal species, we conclude that M. alticola is a junior synonym of B. brunneipennis. In the identification key provided by Stange et al. (2003), B. brunneipennis is described to have several interconnected veins in the costal area of the fore wings and the wing membranes yellowish-brown, thus differing from the species M. alticola. However, the interconnected veins are not present in the holotype, and the yellowish-brown coloring of the wings is likely only a variation. In Wang et al. (2018), B. brunneipennis was described to have large, white pterostigma as in B. asakurae, which is not present in the holotype. Such a misunderstanding might be caused by an error in a figure of the wing tip of B. asakurae wrongly captioned as B. brunneipennis in Stange et al. (2003: fig. 63 b). Additionally, Hagenomyia pterostigma Yang, 1999 from China was synonymized with B. brunneipennis mainly due to the large pterostigma (Bao et al. 2007; Wang et al. 2018). This synonym may be wrong and that name could be a synonym of B. asakurae, but because we have not examined any specimen from China, we do not propose this synonymy here.	en	Lin, Yu-Hsiu Hugh, Ko, Chiun-Cheng, Tseng, Hui-Yun (2024): Taxonomic revision of the antlion tribe Myrmeleontini (Neuroptera: Myrmeleontidae) of Taiwan.

0384E974FF81965FFDBCFE98FBBB9116.taxon	discussion	Remarks Myrmeleon consists of around 180 species with similar combination of characters (Stange 2004; Machado et al. 2019; Oswald 2024). Due to the recovery of this genus as paraphyletic by Michel et al. (2017) and Machado et al. (2019), more morphological characters are needed for resolving the complex relationship among Myrmeleon and the other Myrmeleontini genera. Here, the Taiwanese species can be assigned to four distinct species groups due to several morphological characters.	en	Lin, Yu-Hsiu Hugh, Ko, Chiun-Cheng, Tseng, Hui-Yun (2024): Taxonomic revision of the antlion tribe Myrmeleontini (Neuroptera: Myrmeleontidae) of Taiwan.

0384E974FF9A965AFD89F992FABA9238.taxon	discussion	Remarks Several characters of the sole species of this group, including longer hindwings and the interconnected crossveins on the costal area (Fig. 11 C), are similar to the species of Baliga, but remaining characters such as the overall morphology of the larvae (IX abdominal sternite with one or more row of digging setae) (Lin et al. 2021: figs 3 e, 4 e, 10), and the male genitalia and female terminalia (female anterior gonapophyses about half length of posterior gonapophyses) (Figs 12 – 13) suggest that this species group is distinct from Baliga. Hassan et al. (2022) described Baliga kashimirensis from Pakistan but based on the male genitalia and female terminalia, this species should belong to the M. littoralis group as well.

0384E974FF9B9655FDE6FD98FBC39401.taxon	discussion	Remarks This is a dominant species in Taiwan, the overall markings on the head and thorax make this species easy to identify (Fig. 11 A – B). This species is similar to Myrmeleon coalitus Yang, 1999 from southeastern China in overall appearance and the species status of whether M. littoralis is a junior synonym of M. coalitus requires further confirmation (Yang 1999; Wang et al. 2018).	en	Lin, Yu-Hsiu Hugh, Ko, Chiun-Cheng, Tseng, Hui-Yun (2024): Taxonomic revision of the antlion tribe Myrmeleontini (Neuroptera: Myrmeleontidae) of Taiwan.

0384E974FF949654FD77FB53FC8A9115.taxon	diagnosis	Diagnosis The M. wangi group can be characterized by the hindwing shorter than the forewing; hindwing RP at origin runs closer to MA; male genitalia with gonarcus arched, membrane with short black setae, mediuncus well sclerotized, inverted V-shaped in caudal view, parameres well sclerotized, triangular in caudal view, the larvae with brown markings on coxae.	en	Lin, Yu-Hsiu Hugh, Ko, Chiun-Cheng, Tseng, Hui-Yun (2024): Taxonomic revision of the antlion tribe Myrmeleontini (Neuroptera: Myrmeleontidae) of Taiwan.

0384E974FF949654FD77FB53FC8A9115.taxon	discussion	Remarks Several other Old World species have a similar structure in the male genitalia comparing with M. wangi, including M. formicarius, M. punicanus and M. trivialis. The male genitalia of these species are similar to those of M. wangi in the overall shape of the gonarcus and with short, black setae on the membrane. However, the mediuncus of M. wangi is an inverted V-shape in caudal view (Fig. 16 C), as the mediuncus of the other three species appears to be three-pronged. The male genitalia of these species can be distinguished from those of Baliga by the presence of short, black setae on the membrane, as well as the lack of an additional dorsal process on the mediuncus, which is present in species of Baliga in lateral view (Figs 4 A, 7 A) (Pantaleoni & Badano 2012; Sekimoto 2014; Hassan et al. 2022). The above-mentioned species likely belong to a closely related or the same species group as M. wangi, but additional research is required. If these species are proven to be in the same species group, this group should be redesignated as Myrmeleon formicarius group.	en	Lin, Yu-Hsiu Hugh, Ko, Chiun-Cheng, Tseng, Hui-Yun (2024): Taxonomic revision of the antlion tribe Myrmeleontini (Neuroptera: Myrmeleontidae) of Taiwan.

0384E974FF959650FE01FE66FDAD9510.taxon	discussion	Remarks Myrmeleon wangi Miller & Stange, 1999 was proposed as a junior synonym of Myrmeleon trivialis by Ábrahám (2017). However, he did not mention whether he compared types of both names, but only stated that M. trivialis is widely distributed in the Oriental region and the species is morphologically variable. After comparing the specimens from Taiwan with specimens of M. trivialis from Yunan, China, and images of specimens from Pakistan in Hassan et al. (2022), the two species are different in the male genitalia, particularly the shapes of the mediuncus and parameres (Hassan et al. 2022: fig. 19 e – g). Due to this, it is clear that M. wangi is a separate species from M. trivialis. This species is large-sized, and the adults can be distinguished from the other species from Taiwan by the markings on pronotum (Fig. 14 B).	en	Lin, Yu-Hsiu Hugh, Ko, Chiun-Cheng, Tseng, Hui-Yun (2024): Taxonomic revision of the antlion tribe Myrmeleontini (Neuroptera: Myrmeleontidae) of Taiwan.

0384E974FF91966FFD91FA60FE889297.taxon	diagnosis	Diagnosis The M. punctinervis group is characterized by the hindwing shorter than the forewing; hindwing RP at origin runs closer to MA; male genitalia with gonarcus narrow, arched, crescent-shaped in lateral view, mediuncus well sclerotized, large, trapezoid in caudal view, parameres well sclerotized, large, rectangular in caudal view.	en	Lin, Yu-Hsiu Hugh, Ko, Chiun-Cheng, Tseng, Hui-Yun (2024): Taxonomic revision of the antlion tribe Myrmeleontini (Neuroptera: Myrmeleontidae) of Taiwan.

0384E974FF91966FFD91FA60FE889297.taxon	discussion	Remarks In Miller et al. (1999), the M. punctinervis complex was mentioned, stating that four species were recognized, including M. confusus, M. persimilis, M. taiwanensis, and M. punctinervis, of which confusus being a nomen nudum. Another invalid name M. nigriventris was also mentioned, which is likely an erratum of punctinervis depending from the text. The punctinervis group recognized here is likely to be consistent with the species complex they mentioned. While Miller et al. (1999) suggested that there may be additional species from Taiwan, this has not been confirmed by our investigation. The four species within this group are similar in body size, general appearance, and the shape of the male genitalia. The larvae of this group can all be found on the coast, with M. punctinervis also inhabiting inland riverbanks (Miller et al. 1999; Stange et al. 2003; Lin et al. 2021). A similar structure of the male genitalia is also seen in many species of Myrmeleon, including M. otiosus (Navás, 1912), M. solers Walker, 1853, M. mariaemathildae Pantaleoni et al., 2010, M. almohadarum Badano et al., 2016, M. regularis (Esben-Petersen, 1918), M. immanis Walker, 1853 M. inconspicuus Rambur, 1842 and M. capito Navás, 1912 (New 1985, 1990; Pantaleoni et al. 2010; Krivokhatsky 2011; Sekimoto 2014; Badano et al. 2016). This may indicate a close relationship among these species and the punctinervis group from Taiwan, resulting in a larger species group. Confirmation will require additional material and research.	en	Lin, Yu-Hsiu Hugh, Ko, Chiun-Cheng, Tseng, Hui-Yun (2024): Taxonomic revision of the antlion tribe Myrmeleontini (Neuroptera: Myrmeleontidae) of Taiwan.

0384E974FFAE966BFDE2FCF9FDBA94FC.taxon	discussion	Remarks This is the smallest species of Myrmeleon in Taiwan. The overall morphology of the adult resembles M. persimilis in several characters such as small body size, shorter hindwings, the disposition of digging setae on IX abdominal sternite, and the absence of setae on the ventral side of the mandibles of the larvae (Lin et al. 2021). The two species can be distinguished by the markings on the pronotum of the adults (Figs 17 B, 20 B). This species also resembles M. solers in the markings on the pronotum of the adults (Sekimoto 2014: figs 1 e – f), and comparison of specimens will be needed to confirm the relationship between, M. solers and M. heppneri.	en	Lin, Yu-Hsiu Hugh, Ko, Chiun-Cheng, Tseng, Hui-Yun (2024): Taxonomic revision of the antlion tribe Myrmeleontini (Neuroptera: Myrmeleontidae) of Taiwan.
