Key to species of Erimococcus based on morphology of adult females

1. Cerarii reduced to fewer than 8 pairs; quinquelocular pores on venter absent or very few and restricted to around mouthparts..................................................................................................... 2

- Cerarii always more than 8 pairs; quinquelocular pores on venter abundant on head, thorax and abdomen............... 4

2. Multilocular disc pores absent on dorsum; quinquelocular pores absent on venter............... E. ozani Kaydan sp. nov.

- At least a few multilocular disc pores present on dorsum on posterior abdominal segments; quinquelocular pores present on venter, at least around mouthparts........................................................................ 3

3. Each cluster of oral collar tubular ducts on dorsum of abdominal segments V–VII and ventrally on thorax and first 3 abdominal segments with 1 or 2 multilocular disc pores; oral collar tubular ducts present ventrally on head and thorax.................................................................................... E. talhouki (Matille-Ferrero) comb. nov.

- Most clusters consisting of just oral collar tubular ducts, without multilocular disc pores; dorsal multilocular disc pores restricted to very few on abdominal segments VI and VIII; oral collar tubular ducts absent ventrally on head and thorax............................................................................... E. limoniastri (Priesner & Hosny)

4. Multilocular disc pores absent on dorsum..................................... E. multitubulatus (Danzig) comb. nov.

- Multilocular disc pores present on dorsum.................................................................. 5

5. Dorsal multilocular disc pores mainly present in transverse lines on posterior abdominal segments, although single disc pores occasionally present more anteriorly....................................................................... 6

- Dorsal multilocular disc pores present more or less evenly scattered throughout......... E. salviae (Hadzibejli) comb. nov.

6. Each cluster with at least 2 or more larger oral collar tubular ducts; clusters in distinct transverse rows on all dorsal abdominal and thoracic segments but absent from head............................. E. montanus (Bazarov & Babaeva) comb. nov.

- Each cluster with only 1 larger oral collar tubular duct; clusters randomly distributed on head, thorax and abdomen.............................................................................. E. kimmericus (Kiritchenko) comb. nov.
