Myrmeleon bore ( Tjeder, 1941)

Grocus bore Tjeder, 1941: 74 . Type localities: Sweden and Norway.

Myrmeleon exigus Yang, 1999: 148 . Type locality: China (Fujian: Dongshan).

Myrmeleon tschernovi Krivokhatsky & Shapoval, 2014: 173 . Type locality: Russia.

Diagnosis

Myrmeleon bore can be characterized by wholly dark brown vertex without yellow markings and the pronotum with lateral margins narrowly yellow on proximal half ( Aspöck et al. 1980: fig. 822; Ábrahám & Papp 1991: fig. 2; Monserrat & Acevedo 2013: fig. 39; Tillier et al. 2013: fig. 13; Ábrahám & Giacomino 2020: fig. 3), while the species recorded from Pakistan have yellow markings on a vertex in dorsal view and the pronotum medially brownish yellow ( Akhtar et al. 2018: fig. 2a). This character suggests that the specimens from Pakistan identified as Myrmelon bore belong to a different species.

Remarks

Myrmeleon bore seems widely distributed in the Palaearctic Region and was recently recorded from Pakistan. Notably, Enza otiosus Navás, 1912 has long been considered a secondary synonym of M. bore ( Stange 2004; Sekimoto 2014; Wang et al. 2018). However, based on the priority of the nomenclature of the ICZN (International Code of Zoological Nomenclature), the validity of E. otiosus should be restored and transferred to Myrmeleon , then M. bore should be treated as a synonym of the former. Meanwhile, Kuwayama (1962) did not treat E. otiosus as a synonym for M. bore formally. Considering the type localities between E. otiosus (holotype in Japan) and M. bore (syntypes in Sweden and Norway) have great distance, the relationship between both species needs to be further investigated. Hence, we do not include E. otiosus in the citation of M. bore .

Distribution

Pakistan? Widespread in Palaearctic Region ( Röhricht 1998; Aspöck et al. 2001; Bao & Wang 2006; Akhtar et al. 2018; Yang et al. 2018; Hassan et al. 2019; Ábrahám & Giacomino 2020; Oswald 2020).
