List species and varieties by family
Pseudocyclopidae Giesbrecht, 1893 ( Pseudocyclopoidea )
(1) Pinkertonius Bradford-Grieve, Boxshall & Blanco-Bercial, 2014
Rem.: Type: Pinkertonius ambiguus Bradford-Grieve, Boxshall & Blanco-Bercial,2014. Total: 1 sp.
For Bradford-Grieve & al; (2014, p.528) the most distinctive shared characteristics that link this genus to the family Pseudocyclopidae are:
1- Absence of an aesthetasc on ancestral antennular segment IV;
2- Presence of a well-developed, elongate 2-segmented mandibular endopod with 10 terminal setae;
3- Presence of 9 setae on the coxal epipodite of Mx1;
4- Presence of a posterior surface process on the basis of P1;
5- Exopod segment 2 of female P5 distally extended, and articulation between segments 2 and 3 at an oblique angle to the main axis of the limb;
6- Right exopod segment 2 of male P5 with a triangular inner process and left exopod segment 2 with a scapel-like inner projection that is directed distally.

[1] Pinkertonius ambiguus  Bradford-Grieve, Boxshall & Blanco-Bercial, 2014   (F,M)    [Figs]
(2) Pseudocyclops Brady, 1872
Rem.: Hyperbenthic forms generally on a littoral substrate. Type: Pseudocyclops crassiremis Brady,1871. Total: 39 spp. + 1 indet.

Diagnosis from Bradford-Grieve (199 b, p.23):
- Body short and compact, with anterior part considerably swollen.
- Head strongly vaulted, projecting ventrally an a sharply pointed rostrum, which is moveably connected to the head in male.
- Head and pediger segment 1 separate, pediger segments 4 and 5 fused or separate.
- Urosome 4-segmented in female; 5-segmented in male with a small anal segment.
- Caudal rami short with outermost seta spiniform.
- Eye distinctly developed.
- A1 longer than head, 15-48-segmented; right A1 male distinctly geniculate with the terminal part 4-segmented.
- A2 somewhat cyclopoid in shape; endopod 3-segmented and its distal part is aticulated to proximal segment at nearly a right angle; exopod about as long as endopod and 3-6-segmented.
-Md with distinctly biramous palp.
- Mx1 with the endopod considerably produced.
- Mx2 compact, with all finger-like lobes distinct.
- Mxp hardly longer than Mx2, with reduced setation.
P1-P4 powerfully built with strong outer edge spines on exopods.
P5 female with setae reduced in size, endopod short, 2-3-segmented.
- Male P5 somewhat asymmetrical, right leg larger and hooked at tip, endopod lamellar.

For Zagami & al. (2008, p.611) the five Pseudocyclops species occurring in Lake Faro (Sicily): P. umbraticus, P. xiphophorus, P. costanzoi, P. giussanii and Pseudocyclops sp. are all characterised (according to Ohtsuka & al. 1999) by the following synapomorphies and advanced features by a 2-segmented endopod of the female P5; the distal endopod segment of the female P5 with 1 medial and/or 2 terminal setae, and acute processes terminally; and the number of A1 segments of both sexes being 16 or 17.
The mirus-group shares synapomorphies as follows: 1- absence of exopodal setae along the inner margin of female P5; 2- unarmed proximal endopod segment of female P5, with 2 acute pointed processes; the distal endopod segment of the female P5 with 1 medial and 2 distal setae, and 3 or 4 processes terminally.
Nota: Synapomorphiy: common possession of a derived (apomorphic) homologous character, whereas the symplesiomorphy is the common possession of an ancestral (plesiomorphic) character.
