A review of the Australian species of Ecnomina Kimmins and Daternomina Neboiss (Trichoptera: Ecnomidae) Author Cartwright, David I. text Zootaxa 2008 2008-05-21 1774 1 1 76 https://biotaxa.org/Zootaxa/article/view/zootaxa.1774.1.1 journal article 10.11646/zootaxa.1774.1.1 1175­5334 5124133 Ecnomina chorisis Neboiss Figures 117–119 Ecnomina chorisis Neboiss, 1978: 828 , figs 4–6. — Neboiss 1986: 154 Diagnosis. Ecnomina chorisis is similar to E. cohibilis in possessing broad, fused, inferior appendages, with entire margin, not incised meso-distally, but it is distinguished by inferior appendages with length greater than width. Description. Head, body light brown and wings pale; wings similar to E. legula ( Fig. 3 ). Forewing length about 3 times width: male 2.8 mm . Forewing fork 2 relatively long, sessile, length about 1.3–1.4 times length of fork 3; fork 3 relatively long with short footstalk, length fork greater than 3.2 times length footstalk, footstalk length about 1.2–1.5 times length cross-vein m, r-m and m not contiguous at fork 3 by about 0.5–0.9 times length of cross-vein m; fork 4 shorter than fork 3; fork 5 long, length about 1.8 times length of fork 4. Hindwing length about 3.0–3.2 times width, fork 2 sessile, length about 1.5 times length of fork 3. Male. (Revised after Neboiss 1978 ). Tergum X membranous ( Fig. 119 ). Superior appendages in lateral view, sub-rectangular, length about 3 times width, with a robust, hooked ventro-distal projection ventrobasally ( Fig. 117 ); in dorsal view, length about 3.5 times width, with two pairs of small meso-subapical teeth ( Fig. 119 ). Phallus generally tube-like, with a pair of elongate parameres dorso-laterally ( Fig. 117 ). Inferior appendages fused, dorso-ventrally flattened, up curved laterally; in ventral view, large, broad, length about 1.2 times width, entire margin distally ( Fig. 118 ); in lateral view, length about 2.5 times width, broad near middle, tapered distally ( Fig. 117 ). Female. Unknown. Material examined: Holotype male , Queensland , Fraser Island , Little Minker Lake , 18 Dec 1975 , H. Burton ( NMV , T-5698, specimen PT-548 figured). Remarks. Ecnomina chorisis appears to be restricted in distribution and probably is rare as it has been collected from the type locality only, in south-eastern Queensland (latitude 24°54'S ). Neboiss’s (1978) figures have been redrawn to allow direct comparisons and to accompany the description that is revised in light of new interpretations of Ecnomina genitalic and wing structures.
