Genus Pseudocleobis Pocock 1900

Pseudocleobis Pocock 1900a: 304; Kraepelin 1901a: 108; Roewer, 1934: 602; Mello-Leitão, 1938a: 23; Muma, 1971a: 14-16; Muma, 1976: 28.

Tetracleobis Roewer, 1934: 605; Muma, 1976: 28 (synonymized by Maury, 1976: 93).



Diagnosis:


Pocock (1900) characterized the genus as follows:

 

"Differing from Cleobis Sim., as recently restricted and defined by Kraepelin (Jahrb. Hamb. Wiss. Anst. xvi. pp. 223-227, 1899) in the following particulars:-

The tibia and protarsus of the palp are furnished below with short paired spines in both sexes. In the male the third tooth of the upper jaw is larger than the first and much larger than the second, which is minute and lodged in between the other two. In the female the third tooth is also larger than the first and second, but its basal width is less than that of these two teeth taken together.

Also allied to Mummucia, but having the fourth tarsus distinctly trisegmented."


Roewer (1934) characterized the genus as follows:


"Ammotrechinae, deren 2. und 3. Tarsus ventral mit jeweils 1.2.2.4 Dornen und deren 4. Tarsus ventral mit 2.2/2/2.4 Dornen bewehrt ist (Abb. 335, f, k); Cheliceren am unbeweglichen Finger vor den 1 oder 2 Zwischenzähnen mit 3 Vorderzähnen, deren erster größer ist als der zweite und kleiner als der dritte, und am beweglichen Finger ohne einen medialen Wangenzahn neben dem Hauptzahn (Abb. 341, a-e)."


[Ammotrechinae whose 2nd and 3rd Tarsus each bear 1.2.2.4 ventral spines and whose 4th Tarsus bears 2.2/2/2.4 ventral spines (Fig. 335, f, k); Fixed cheliceral finger with 2 anterior teeth in front of the 1 or 2 intermediate teeth, of which the first is greater than the second and smaller than the third, and movable cheliceral finger without a medial cheek tooth next to the main tooth (Fig. 337, a-e).]


In the same publication, Roewer (1934) diagnosed the genus Tetracleobis, later regarded as a synonym of Pseudocleobis by Maury (1976), as follows:


Ammotrechinae, deren 2. und 3. Tarsus ventral mit jeweils 1.2.2.4 Dornen und deren 4. Tarsus ventral mit 2.2/2/2.4 Dornen bewehrt ist (Abb. 335, f, k); Cheliceren am unbeweglichen Finger mit 4 Vorderzähnen vor den 2 Zwischenzähnen und am beweglichen Finger ohne einen medialen Wangenzahn neben dem Hauptzahn (Abb. 341, f).


[Ammotrechinae whose 2nd and 3rd Tarsus each bear 1.2.2.4 ventral spines and whose 4th Tarsus bears 2.2/2/2.4 ventral spines (Fig. 335, f, k); Fixed cheliceral finger with 4 anterior teeth in front of the 2 intermediate teeth, movable finger without a medial cheek tooth next to the main tooth (Fig. 341, f).]
