Triphleba aequalis (Schmitz, 1919) (Figs 81–84) Trupheoneura aequalis Schmitz, 1929: 189 (male). The hitherto unknown female is described below. In the key of Schmitz (1943) it runs to couplet 57, lead 1 to T. excisa. However, its female sternite 7 has much shorter posterolateral processes (Fig. 168 in Disney 1983). The subsequently described T. bifida Schmitz (1949) runs to the same point in the key and its sternite 7 closely resembles that of T. aequalis but with shorter posterolateral processes (Fig. 85). In addition Schmitz gave its wing length as 2.79 mm, its costal index as 0.55 and its costal ratios as 1.65: 1.35: 1. For the females of T. aequalis reported below these measurements differ a little (see below). It is possible that Schmitz’s measurements represent small extensions of the ranges for T. aequalis and that the shorter posterolateral processes of sternite 7 in T. bifida as figured by Schmitz (Fig. 85) represent a foreshortening due to the tilt of a pinned specimen. If so then T. bifida would become a synonym of T. aequalis. Female. Head as Fig. 81. Abdominal tergites 1–6 brown with moderate hairs. T6 longer than T5 and slightly tapered and T7 represented by hairs only. Sternite 7 as Fig. 82. Hind femur and tibia as Fig. 83. Wing (Fig. 84) 2.11–2.26 mm long. Costal index 0.50–0.54. Costal ratios 1.72–2.13: 1.44–1.68: 1. Previously Known from Austria, Czech Republic, Denmark, France, Germany, Hungary, Italy, Poland, Spain, Sweden. Material examined. 2 males, 4 females, Finland: Lkor: Savukoski, Ainijärvi 7522397:3602914 and 7522293:360311, 30 Jul–28 Sep 2015, J. Salmela leg. (Malaise trap) (UCMZ, 34-187, 189).
