Key to the species of Pseudolorryia Kaźmierski

1. Palptarsus eupathidium (p’ζ) simple, rod- or thumb-like, rounded distally; seta d on palptarsus simple, not forked; ornamentation variable in type.................................................................................... 2

- Palptarsus eupathidium (p’ζ) not simple, with goblet-shape or “T”-shape tip, or cleft distally; seta d forked; ornamentation type “ Tydeus ”............................................................................................ 5

2. Dorsum of opisthosoma reticulated........................................................................ 3

- Dorsum of opisthosoma striated..........................................................................4

3. “Mountains-shaped” reticulation grouped into regular regions; dorsal idiosomal setae “rough” only............................................................................................. .. P. edwardbakeri Kaźmierski, 1989

- Dorsal reticulation flat; no separate regions; dorsal setae with small, but distinct serration...... P. taurica ( Kuznetzov, 1971)

4. Cheliceral stilettos (ca 23) longer than palptarsus (ca 18), but shorter than combined length of palptarsus and its rod-like terminal eupathidium (18+14); striation type “ Paralorryia ”; dorsal idiosomal setae sickle-like, serrate, subequal in length...................................................................................... P. nikitensis (Livshitz, 1973)

- Cheliceral stilettos not shorter than 40, i.e. significantly longer than combined length of palptarsus and its thumb-like terminal eupathidium (14+6); striation type “ Tydeus ”; dorsal idiosomal setae pointed, smooth; setae ps1 and especially h2 distinctly longer than other setae.................................................... P. striata (Momen & Lundqvist, 1996)

5. Reticulation on aspidosoma forming area ( ro)( bo)....................... P. andreae (Ueckermann & Smith Meyer, 1979)

- Reticulation absent.................................................................................... 6

6. Cheliceral stilettos distinctly longer than combined length of palptarsus and its terminal eupathidium; all dorsal idiosomal setae sharpointed...................................................................................... 7

- Cheliceral stilettos distinctly shorter than combined length of palptarsus and its terminal eupathidium; at least some dorsal idiosomal setae pointed.................................................................................9

7. Opisthosomal dorsal setae extremely strongly spined, with a few branches on bases; dorsal striae strong, with rectangular tubercles........................................................................ P. spinea (Livshitz, 1973)

- All dorsal idiosomal setae “rough” only, without distinct serration; dorsal striae subtle, close, with small rods or “I”-shaped costulae.............................................................................................8

8. Tectal setae on tarsus I inserted in tubercle-like convexities; empodial hooks absent (only a short thorn at base of empodium); no “swirls” in dorsal ornament; lyrifissure ia lies closer to c2 than c1............................ P. starri ( Baker, 1944)

- No tubercle-like tectal convexities; empodial hooks well developed, curved; a pair of “swirls” occur between setae c1 and c2 on both sides; lyrifissures ia lie in range of “swirls”, closer to c1 than to c2............... .. P. nicaraguensis ( Baker, 1970)

9. Dorsal idiosomal setae club-like and nude; cheliceral stilettos shorter than palptarsus; ventral striation between metasternal setae longitudinal.................................................................................... 10

- Dorsal idiosomal setae not club-like, distinctly serrated; cheliceral stilettos as long as palptarsus; ventral striation between metasternal setae transverse or form “V” pattern............................................................ 11

10. Dorsal striae between d1 transverse; empodial claws present........................... .. P. fustis (Ueckermann, 1988)

- Dorsal striae between d1 longitudinal; empodial claws absent............... P. pseudofustis ( Theron & Ueckermann, 2012)

11. Dorsal setae extremely variable in length; setae ro and f1 short, pointed; setae c1 and d1 longer, stick-like; setae la, ex, c2, e1 and f2 very long (longer than bothridial setae), club-like; setae h1 short, club-like; setae h2 and ps1 very short, broadly clublike, situated ventrally and very closely to each other; solenidion ωI short; empodial hooks ( om) very small, near empodial base; ventral situation transverse between metasternal setae............................. P. turrialbensis ( Baker, 1970)

- Dorsal setae subequal in length, distinctly shorter than bothridial setae; aspidosomal setae, as well as setae c lanceolate, curved and almost sharp; setae d1 and e1 lanceolate, but rounded distally; setae f spatulate; setae h and ps1 broader and spatulate distally ( h2 situated dorsally, ps1 situated terminally); solenidion ωI long; empodial hooks thick and strong; ventral situation “V”- shaped between metasternal setae...................................................... P. mumai ( Baker, 1970)
