Ecnomina View in CoL foramen sp. nov.
Figs 156–158 View FIGURES 153–161
Diagnosis. Ecnomina foramen closely resembles other species in the group in possessing one pair of relatively robust dorsal processes on tergum X and meso-distally excised and fused inferior appendages. It is distinguished by tergum X with short, narrowly separated processes and inferior appendages without disto-lateral projections.
Description. Head, body and wings light brown, abdomen paler ventrally; wings similar to E. merki ( Fig. 172 View FIGURES 168–174 ). Forewing length about 2.6–2.7 times width: male 3.0– 3.4 mm. Forewing fork 2 relatively long, sessile, length about 1.2–1.6 times length of fork 3; fork 3 relatively long, with short footstalk, length fork about 2.5– 4.6 times length footstalk, footstalk length about 1.1–1.6 times length cross-vein m, r-m and m nearly contiguous at footstalk fork 3, r-m and m separated by about 0.3–0.9 times length of cross-vein m; fork 4 slightly shorter than fork 3; fork 5 long, length about twice length of fork 4. Hindwing length about 2.8 times width, fork 2 sessile, length about 1.4–1.7 times length of fork 3.
Male Tergum X membranous, with one pair of relatively short, simple dorsal processes, narrowly separated ( Fig. 158 View FIGURES 153–161 ). Superior appendages in lateral view, dilated slightly near middle, length about 2.5 times width ( Fig. 156 View FIGURES 153–161 ); in dorsal view, length about 4 times width, dilated slightly and with several spines distally ( Fig. 158 View FIGURES 153–161 ). Phallus simple, tube-like, obliquely truncate distally, with several short spines dorsally ( Fig. 156 View FIGURES 153–161 ). Inferior appendages short; in ventral view, fused in basal half, dilated and truncated distally, with oval excision meso-distally, length about two thirds width ( Fig 157 View FIGURES 153–161 ); in lateral view, dilated slightly distally, length about three times width ( Fig. 156 View FIGURES 153–161 ).
