The two lateral black stripes of synthorax, the second and the third according to Zhao (1990), are usually distinct and entire in males (Fig. 1); the variation of this character seems sex-related, as the females exclusively have the second stripe broken at the middle for a distance around 1/3–1/2 length of the stripe, and the third stripe becomes narrower and indistinct toward the lower end (Figs 2 &amp; 11). Other variations of body pattern in the Taiwanese F. prometheus include the paired spots on the labrum and the extent of antehumeral stripes. The paired yellow labral spots are usually absent (Fig. 3) but can be present in few specimens. The antehumeral stripes are usually vestigial, leaving only an upper spot and rarely also a lower short stripe (Figs 1 &amp; 2); in few female specimens, a short lower stripe is present and sometimes even connected to the upper spot to form a short antehumeral stripe (Fig. 11). Considering the variations mentioned above, the body pattern of the holotype of S. takashii as shown here (Figs 4 &amp; 7) does not differ from those found in the female Taiwanese F. prometheus .</p><p>In morphology, the female F. prometheus is characterized mainly by a short spine locating on the outer-posterior corner of the lateral ocellus, in additional to a larger, low and obtuse tubercle on the inner-posterior corner (Fig. 3). Further, the female subgenital plate of F. prometheus is equilaterally triangular, with the length as long as 1/4 of the 9th abdominal segment; the plate is divided by a middle slit running from the apex to around basal 1/2 of the plate (Fig. 5). These morphological characters fit well also with those of the holotype of S. takashii mentioned by Asahina and examined by us (Figs 4 &amp; 8).</p><p>Distribution. China (Zhejiang, Fujian, Guangdong and Hainan); Taiwan (Taipei, New Taipei, Taoyuan, Keelung, Hsinchu, Miaoli and Nantou), Vietnam (Lieftinck et al. 1984; Kompier 2015; Zhang 2019; this study). The distributional map of F. prometheus in Taiwan is shown in Fig. 15.</p><p>Ecology. The habitats of F. prometheus observed in northern Taiwan are mainly shaded creeks (Fig. 12) or tiny muddy trenches in well-forested areas. The females usually oviposit alone at the shallow margins of small pools in creeks, or in trenches fed by the water from nearby seepage. The territorial males often perch on undergrowth vegetation near the female oviposition sites, sometimes as low as 10 cm above the ground. In Guangdong, F. prometheus inhabits shady seepages, narrow creeks with slow-flow and marshes or pools with thick bottom silt. In Pingan and Tonghou where the oviposition sites are semi-shaded tiny trenches, the ovipositing behaviors of females were stealth and difficult to discover, usually undertook under the coverage of dense weeds growing along the banks of trenches. The females perform egg-gathering behaviors before each dipping to release the eggs, either by hovering still low in the air above the water or sitting on vegetation adjacent to the dipping site. The larvae dwell on muddy seepages with weedy vegetation or amongst the detritus accumulated at the bottom of tiny trenches or pools in creeks. In Taiwan, F. prometheus is confined in low mountainous areas in the north, ranging from 40–1100 m.a.s.l. in elevation; the only exceptional record is the type locality of S. takashii in Nanshanshi where it is located in Nantou County in central Taiwan (Fig. 15).</p></div>	https://treatment.plazi.org/id/ED3D87AEFFE1FF9AFF79E6B9FD5BFAAF	Public Domain	No known copyright restrictions apply.
