Ascalaphus dicax Walker 1853

Ascalaphus dicax Walker, 1853 Ascalaphus dicax Walker, 1853: 423. Type locality: India. Diagnosis. Ascalaphus dicax can be easily distinguished by the angled antenna at the proximal region in the male, with short black setae on basal flagellomeres, while straight in female. Although this species shows similarities with the other two congeners known from Pakistan, it can be distinguished from A. prothoracicus due to the absence of a well-developed triangular process on the mesonotum which is present in A. prothoracicus, and from A. abdominalis due to lack of well-develpoed median dilation on the lateral margin of abdominal tergum 4, which is well-developed in A. abdominalis. Distribution. Pakistan (exact location unknown, it might be distributed in Punjab province); Bangladesh, China (Guangxi, Guizhou), India (Assam, Himachal Pradesh, Odisha, Uttar Pradesh, West Bengal), Iraq, Saudi Arabia, Indonesia, Syria, Japan, Philippines, Sri Lanka (Sziráki 1998; Ghosh 2000; Whittington 2002; Yang et al. 2018; Hassan et al. 2019).Published as part of Hassan, Muhammad Asghar & Liu, Xingyue, 2021, Taxonomic notes on owlflies from Pakistan (Neuroptera: Myrmeleontidae Ascalaphinae), pp. 401-452 in Zootaxa 4970 (3) on page 408, DOI: 10.11646/zootaxa.4970.3.1, http://zenodo.org/record/476654
