Pompholyx Gosse, 1851

[ref. ID; 1663]
Lateral edges of dorsal and ventral plates of lorica closely confluent. Flat or four-lobed in cross section. Corona without finger-like processes. Two frontal eyespots. Mastax malleoramate. Trophi symmetrical. (ref. ID; 1663)

Lorica almost circular with the dorsal plate having a pointed protuberance in the middle. (ref. ID; 2715)
Measurements; Length 114 um. (ref. ID; 2280)
Length of lorica 62; width 39 um. (ref. ID; 2715)
Total length 90; width 81 um. (ref. ID; 2860)
Pompholyx sulcata Gosse, 1851 (ref. ID; 1804, 1923) reported author and year? (ref. ID; 3073)
Description; This species is very common in ponds and lakes. (ref. ID; 1923)
Lorica egg shaped; divided into four lobes in cross-section. Frontal edge raised into a lobe-like projection dorsally, two elevations laterally and a shallow sinus ventrally. Cloacal aperture situated posteriorly. Egg connected by elastic threads to the posterior end of lorica. (ref. ID; 1804)
Measurements; Total length 84; maximum width 68 um. (ref. ID; 1804)
Body length 120 um. (ref. ID; 1923)
Pompholyx sulcata Hudson, 1885 (ref. ID; 1345, 1847, 2269, 2280, 3059, 3083, 3114, 3514, 3688) reported year? (ref. ID; 2619, 3046, 3064, 3072, 3239)
Description; Organisation (ref. ID; 3072 )
[Male]: Male present. (ref. ID; 3064)
[Egg]: Mode of egg-carrying. (ref. ID; 3072 )
Measurements; Total length 115 um. (ref. ID; 2280)
Dorsal lorica length 92-106; widest part 80; highest part 71-78; caudal projection or protuberance (for Gosse's threads) 10-12 x 5-10 in size. (ref. ID; 3083)
Pompholyx triloba Pejler, 1957 (ref. ID; 3257 original paper)
Description; The dorsal side had a bulge, resembling that in P. sulcata Hudson. The ventral side, however, lacked such a bulge. This produces in the outline of the cross-section three rounded lobes, which are alluded to by the name Pompholyx triloba. In dorsal or ventral view, the lorica does not exhibit any greater differences from that of P. sulcata or that of P. complanata Gosse. (ref. ID; 3257)
Comments; Pompholyx sulcata and P. triloba have never been found in the same waters. The former species has been encountered only in real lakes which are larger throughout than the three waters in which P. triloba has been found. This circumstance suggests that the two species are vicariating ecologically for one anther. No intermediate forms between P. sulcata and P. triloba have been observed, nor between P. triloba and P. complanata. (ref. ID; 3257)
Measurements; Length of lorica 80-95 um. (ref. ID; 3257)
Pompholyx trilobata Pejler, 1957 (ref. ID; 1923)
Description; This species has 3-lobed cross section. (ref. ID; 1923)
Pompholyx tubulosa Berzins, 1982 (ref. ID; 4606 original paper)
Description; This is similar to complanata, but flatter. Most differed from other Pompholyx having well shaped tubus at the anal opening which passed the lorica posteriorly. Eggs are often attached to this. (ref. ID; 4606)
Type locality; In the plankton of Lake Purumbete. (ref. ID; 4606)
Measurements; Lorica length/width 100/71, 99/71, 106/75 um. (ref. ID; 4606)
