Procladius (Holotanypus) paragretis Roback (Figs 8 D, E; 10 D) Procladius (Procladius) paragretis Roback, 1971: 185; Roback 1980: 38; Saether 1977: 48. 8. Procladius spp., male. A–C. Procladius (H.) freemani Sublette; A–cibarial pump, tentorium and stipes; B—thorax; C—hypopygium. D–E. Procladius (H.) paragretis Roback; D—cibarial pump, tentorium and stipes; E—hypopygium. Material examined . CANADA: Manitoba, Lake Winnipeg, 2 km off Selkirk (Horse) Island, light trap, 1 female, 7.vi. 1969; Matheson Island to Gimli Government Wharf, 6 males, 24.vii. 1969; Grand Rapids Government Wharf, 3 males, 28.vii. 1969. The gonostylus ratio (Fig. 8 E) of the males from Lake Winnipeg is 1.59–2.05, 1.91 (4) and thus an extension of Roback’s measurement for Procladius gretis Roback (1.58–1.70). In all other details, however, the males conform to P. paragretis. The female probably belonging to P. paragretis has about 15 setae on anepisternum II, about 34 setae on segment X, and about is 10–14 sensilla chaetica on each ta t of p 2 and p 3. The genitalia are illustrated in Fig. 10 D. Distribution and ecology . Roback (1971: 1.85) records the holotype and allotype from Greenland. The specimens from the northwestern parts of Lake Winnipeg and a female from Feniak Lake, Notak River Basin, Alaska (8 / 7 / 73, D. Huggins), are the only other records. : Published as part of Saether, Ole A., 2010, Procladius Skuse from Lake Winnipeg, Manitoba, Canada, with keys to some females and immature stages of the genus (Diptera: Chironomidae), pp. 34-58 in Zootaxa 2726 on pages 44-45, DOI: 10.5281/zenodo.200030 : {"references": ["Roback, S.
