Key to some females of Procladius  

A preliminary key to females primarily based on Lake Winnipeg specimens was presented by Saether (1977). Procladius   sp. n. in that paper is identical to Procladius rugulosus   sp. n. in the enlarged key below. Roback (1966, 1971) and Wrubleski & Roback (1987) describe a number of female Procladius   ( Psilotanypus   ). However, only the last paper incorporate the details of the female genitalia necessary for placing most of the species in a key.

1. Apex of gonapophysis VIII tongue-shaped; wing membrane without setae; segment X with 7–22 setae..................................................................................... Procladius   subgenus Psilotanypus Kieffer   2

- Apex of gonapophysis VIII triangular; wing membrane with setae; segment X with 16–58 setae......................................................................................... Procladius   subgenus Holotanypus Roback   4

2. Apex of gonapophysis VIII curved ( Saether 1977 fig. 20 C); abdomen pale to light brown with caudal edges of tergites narrowly light ( Roback 1971 fig. 278)............................................... P. (Psilotanypus) bellus (Loew)  

- Apex of gonapophysis VIII straight, parallel-sided ( Roback 1987 fig. 32); abdomen wholly brown..................... 3

3. Wing with some setae towards apex; area around RM broadly infuscate.................. P. (Psilotanypus) nietus Roback  

- Wing without setae towards apex; area around RM not infuscate......................................................................................................................... P. (Psilotanypus) deltaensis Roback  

4. With 3–4 supraalars (postalars in Roback 1971), about 30 humerals, and eye ratio (distance between dorsal eye extension divided by length of extension) 2.0; abdomen not banded.............................. P. (Holotanypus) desis Sublette  

- With 1–3 supraalars, 14–30 humerals, and eye ratio 2.1–3.1. When more than 1 supraalar eye ratio 2.5–3.1, when more than 2 supraalars about 14 humerals; abdomen occasionally banded................................................... 5

5. Abdomen with indication of banding; anepisternum II without setae; segment X with about 25 setae; about 9–14 sensilla chaetica proximally on each basitarsus of middle and hind leg........................... P. (Holotanypus) freemani Sublette  

- Abdomen not banded; anepisternum II with or without setae; segment X with 16–18 or 20–58 setae; 3–14 sensilla chaetica on each basitarsus of middle and hind leg..................................................................... 6

6. Segment X with about 16–18 setae; anepisternum II without setae; about 3–10 sensilla chaeticae proximally on each basitarsus of middle and hind leg............................................................... P. (H.) sublettei Roback  

- Segment X with about 20–58 setae; anepisternum II usually with setae; 3–14 sensilla chaeticae proximally on each basitarsus

of middle and hind leg.................................................................................. 7 7. Segment X with about 56–58 setae; anepisternum II with 0–5 setae; about 9–14 sensilla chaeticae proximally on each basitarsus of middle and hind leg......................................................... P. (H.) denticulatus Sublette  

- Segment X with about 20–40 setae; anepisternum II with 3–15 setae; about 3–14 sensilla chaeticae proximally on each basitarsus of middle and hind leg............................................................................... 8

8. Segment X with 20–30 setae; anepisternum II with 6–8 setae; 3–8 sensilla chaeticae on each basitarsus of middle and hind leg.................................................................................. P. (H.) culiciformis   (L.)

- Segment X with about 34–40 setae; anepisternum II either with about 3 or about 15 setae; either 4–5 or 10–14 sensilla chaeticae on each basitarsus of middle and hind leg............................................................... 9

9. Anepisternum II with about 15 setae; 3–4 supraalars; about 10–14 sensilla chaeticae on each basitarsus of middle and hind leg................................................................................ P. (H.) paragretis Roback  

- Anepisternum II with about 3 setae; 1 supraalar; 4–5 sensilla chaeticae on each basitarsus of middle and hind leg............................................................................................ P. (H.) rugulosus   ? sp. n.
