Key to the species of Paralorryia Baker

1. Ornamentation type “ Paralorryia ” (longitudinal striation between setae d1)........................................ 2

- Ornamentation type “ Tydeus ” (transverse striation between setae d1).............................................3

2. Reticulation on aspidosoma and opisthosoma; aspidosoma with vast area (ro)(la); Opisthosoma with three large areas: f2-f1, f1-f2 and (h1)(h2)(ps1); in addition, four pairs of small areas (each with one seta): c1, c2, d1 and e1; gnathosoma visible from above; striation subtype “Biparalorryia”; dorsal idiosomal setae rod-like and long: not shorter than bothridial setae with exception of ro; setae f1 longer than distance f1-h1 ........................................ .. P. arthurbakeri ( Baker, 1944)

- Reticulation occurs on aspidosoma only (AA0); gnathosoma concealed from above; striation subtype “ Paralorryia s. str. ”; dorsal idiosomal setae narrowly lanceolate and significantly shorter: two or three times shorter than bothridial setae; setae f1 shorter than distance f1-h1 ......................................................... P. cumbrensis ( Baker, 1944)

3. Reticulation forms relatively vast, rectangular aspidosomal area AA0; dorsal idiosomal setae subequal in length, short, serrated and pointed....................................................................... P. formosa ( André, 1984)

- Reticulation absent; dorsal idiosomal setae unequal in length, shaped differently.................................... 4

4. Dorsal idiosomal setae blunt, club-like (mildly clavate) and serrate; posterior idiosomal setae broader, but shorter than anterior setae......................................................................... P. costaricensis ( Baker, 1970)

- Dorsal idiosomal setae slender, nude and pointed.............................................................5

5. Setae ro, la, c1, d1, e1, f1, h1 and ps1 very short: three times shorter than bothridial setae; setae h2 long (ca 50): distinctly longer than other dorsal setae and similar in length to (bo); no “swirls” between setae c1 and c2........ P. bipilis ( André, 1984)

- No setae very short; shortest setae are: ro, la, c1, d1, e1 and f1, which are at least 1/2 as long as (bo); setae ex, c2, f2, h1, h2 and ps1 are distinctly longer: nearly as long as (bo); “swirls” between setae c1 and c2 present.......... P. shawi ( Baker, 1944)
