However, the combination of a higher antennal ratio, the complete absence of an anal point, and larger median volsella separates the adult males of the two species. Sympotthastia wuyiensis Liu, Ferrington et Wang, 2016 is another species without an anal point. However, S. golalae sp. nov., differs in the shape of superior volsella and the presence of megaseta compared to S. wuyiensis. The prominent adult characteristics of the S. golalae sp. nov. that separate it from other known Sympotthastia species is a larger size and a longer wingspan, which, on average, is 1.3 × for total length and 1.2 × for wing length. Further, a much larger median volsella of S. golalae sp. nov. in comparison to other Sympotthastia species is apparent. The adult female of S. golalae sp. nov. is easily distinguishable from the only species described as female, Sympotthastia bicolor (Tokunaga, 1937), by a much larger size, and short and wide ovate seminal capsules with small necks. S. bicolor has elongated ovate seminal capsules with prominent necks (Tokunaga 1937: Fig. 97). The adult male of Sympotthastia can also be separated based on the key we provided in this study. In constructing this key, we used the keys constructed by Doughman 1985, Liu et al. (2016), and Makarchenko (1985) with additions and modifications. In addition to this key, we have listed some relevant distinguishing characteristics of Sympotthastia adult males in Table 6. In constructing Table 6, we consulted the relevant literature that described the Sympotthastia species, and in doing so, we have also made corrections to the previous measurement records. Makarchenko (1985) provided an AR value of 3.48–3.69 for Sympotthastia takatensis (Tokunaga, 1936), under Sympotthastia khorensis. Liu et al. (2016) indicated an AR value of 3.19–3.48 for this species. However, in their diagnosis and the key to adults of Sympotthastia they indicated the AR value of 3.19–4.26. Further, Makarchenko et al. (2022a) indicated an AR value of 2.76–2.81 for S. takatensis from the Republic of Khakassia, Russia. Dr. Wenbin Liu has kindly confirmed that their AR value of 3.19–4.26 is extracted from all S. takatensis reviewed and measured from Russia, Japan, and the Korean Peninsula. Dr. E. Makarchenko has also confirmed their value of 2.76–2.81 for S. takatensis from the Republic of Khakassia. Therefore, it seems this species has a large AR variation across its geographical range, so we considered an AR value of 2.8–4.3 for S. takatensis. This value falls within the AR range value for Sympotthastia huldeni Tuiskunen. Given the similarities in the shapes and sizes of anal point and AL + SVo of S. takatensis and S. huldeni along with their similar AR value, the only characteristic that separates them is the surface of S. takatensis median volsella bearing spinules and its apical edge being smooth whereas S. huldeni has a median volsella with bare surface and serrated apical edge. Dr. Liu has further provided us with a correct VR value of 0.83–0.87, for S. wuyiensis, which should replace the value of 3.29–3.44 previously provided by Liu et al. (2016). Regarding the absence of values for some characteristics of Sympotthastia macrocera Serra-Tosio, 1973 in Table 6, Serra-Tosio (1969) indicated that besides the ratio of palp length to head width, antennal ratio, and more temporal setae, S. macrocera is virtually the same as Sympotthastia spinifera Serra-Tosio, 1969. At the time, he described the species as a variation of S. spinifera; however, later in his 1973 work, Serra-Tosio erected the species based on discovering several other adults and immatures and the consistency of the distinctive characteristics.However, he did not provide any additional description or measurements. The total length and wing length measurements of this species in Table 6 are based on Doughman (1985). There seems to be an inconsistency regarding the morphology terminologies used for the hypopygium of Sympotthastia. Liu et al. (2016) have indicated that what is referred to as superior volsella is, in fact, the aedeagal lobe. This terminology usage follows that of Hansen & Cook (1979) and Oliver (1989), which refer to the structure as the aedeagal lobe or median aedeagal lobe. Hansen &
