Mayfly Species Paraleptophlebia rufivenosa

This is a brownish species without distinct color pattern. The head and thorax and tip of the abdomen are dark brown; middle abdominal segments, legs, and tails paler brown. Wings with reddish longitudinal veins and with the cross veins also tinged except in the basal 3rd; most heavily in the stigmatic region, where the cross veins are oblique, rather crowded, and some of them forked. 9th sternite narrowly divided by a V-shaped notch. Forceps tapering rather regularly from base to apex, slightly corrugated internally; the 3rd segment as large as the 2nd. Penes separated for about half their length by a V-shaped notch that is rounded proximally; their outer margins parallel almost to the tip where a triangular tooth projects laterally. There is no reflexed spur and there is no apical tooth (see fig. 134).
