Key to the species of Metalorryia André

1. Dorsal idiosomal setae nude; palptibia seta short: not longer than 1/3 of length of palptarsus....................................................................................................... M. magdalenae (Gerson, 1968)

- Dorsal idiosomal setae serrate; palptibia seta long: nearly as long as palptarsus..................................... 2

2. Dorsal opisthosomal setae club-like (broadened distally)....................................................... 3

- Dorsal opisthosomal setae lanceolate or leaf-shaped (pointed).................................................. 5

3. Palpal terminal eupathidium (p’ζ) rod-like: not broadened, but rounded distally; bothridial (bo) setae two times longer than others dorsal idiosomal setae, with slender and feeble distal part........................... M. palpsetosa (Karg, 1975)

- Palpal terminal eupathidium (p’ζ) not rod-like, being broadened or cleft, not rounded distally; bothridial (bo) setae nearly the same length of other dorsal idiosomal setae, without slender and feeble distal part..................................4

4. Dorsal idiosomal setae club-like strongly serrated; gnathosoma concealed by aspidosoma; bothridial (bo) setae twice as long as other dorsal setae.............................................................. M. insignita (Kuznetzov, 1971)

- Dorsal idiosomal setae lanceolate slightly serrated; gnathosoma visible from above; bothridial (bo) setae only slightly longer than other dorsal setae.......................................................... M. armaghensis (Baker, 1968)

5. Dorsal setae leaf-shaped: ratio of length to width of each seta about 3:1..................... M. foliata Kaźmierski, 1998

- Dorsal setae lanceolate, much narrower....................................................................6

6. Palptarsal eupathidium simple, rod-like with round tip; seta d on palp forked; solenidion ɷI located anteriorly on palp; multiangular cells (most often hexagonal) and reticulum connected by Y-shaped cross ties; frames of meshes with single I or double II-shaped costulae...................................................... .. M. anchisi Momen & Lundqvist, 2005

- Palptarsal eupathidium with cross-piece on tip (T-shaped); seta d on palp is simple; solenidion ɷI located posteriorly on palp; frames of meshes without I-shaped costulae......................................... M. delicata (Kuznetzov, 1971) junior synonym: M. cristata (Karg, 1975)
