Clinocera stagnalis

Clinocera stagnalis (Haliday) (Fig. 2A) Material examined. L1: 1 ♂. Distribution. According to Sinclair (2008), Clinocera stagnalis is the most widespread species of Clinocerinae, distributed throughout the Palaearctic Region (Europe, the Near East, Central Asia and North Africa), and is also known from the Nearctic (Canada, Greenland and the USA) and Oriental regions (Nepal) (Chvála & Wagner 1989; Sinclair 2008; Ivković et al. 2013, 2017; Słowińska & Jaskuła 2020). This is the first record of the genus and species from Albania. Identification. The present specimen bears the crossvein between R 4 and R 2+3 on the right wing, while it is absent on the left (this common asymmetry was also noted by Sinclair (2008)). Other characters (face completely with greyish-bluish pruinosity, apices of femora reddish) also agree with the description and characters listed by Sinclair (2008), as well as the male genitalia. Remarks. Słowińska & Jaskuła (2020) summarised the knowledge on the Albanian aquatic dance fly fauna and listed four species occurring in the country. They also noted that Albania may still harbour species new to science in this group due to its heterogeneous habitats, including numerous high-altitude areas and diverse waterbodies with several streams. The present record increases the number of aquatic dance fly species known from Albania to five; however, this number remains significantly lower than that of any neighbouring Balkan country (cf. Słowińska & Jaskuła 2020).
