Ammotrechella Roewer, 1934: 594; Muma, 1951: 125; Muma, 1970a: 45; Muma and Nazario, 1971: 506; Muma, 1976: 25; Maury, 1982a: 130; Muma, 1987: 17; Armas, 2004b: 32; Armas and Teruel, 2005: 152.

Ammotrechona Roewer, 1934: 595; Muma, 1970a: 48; Muma, 1976: 26 (synonymized by Armas, 2004b: 60).



Diagnosis:


Roewer (1934) characterized the genus as follows:

 

"Ammotrechinae, deren 2. und 3. Tarsus ventral mit jeweils 1.2.2.1 Dornen und deren 4. Tarsus ventral mit 2.2/2/2 Dornen bewehrt ist (Abb. 335, b, g); Cheliceren am unbeweglichen Finger mit 2 Vorderzähnen vor dem Zwischenzahn und am unbeweglichen Finger mit 1 medialen Wangenzahn neben dem Hauptzahn (Abb. 337, b usw.)."


[Ammotrechinae whose 2nd and 3 Tarsus each bear 1.2.2.1 ventral spines and whose 4th tarsus bears 2.2/2/2 ventral spines (Fig. 335, b, g). Immovable finger of chelicerae with 2 anterior teeth in front of the median tooth and movable finger with 1 medial cheek tooth next to the main tooth (Fig. 337, b etc).]


In the same publication, Roewer (1934) diagnosed the genus Ammotrechona, later regarded as a synonym of Ammotrechella by Armas (2004), as follows:

 

"Ammotrechinae, deren 2. und 3. Tarsus ventral mit jeweils 1.2.2.2 Dornen und deren 4. Tarsus ventral mit 2.2/2/2 Dornen bewehrt ist (Abb. 335, c, g); Cheliceren am unbeweglichen Finger mit 2 Vorderzähnen vor dem Zwischenzahn und am beweglichen Finger mit 1 medialen Wangenzahn neben dem Hauptzahn (Abb. 337, c)."


[Ammotrechinae whose 2nd and 3 Tarsus each bear 1.2.2.2 ventral spines and whose 4th tarsus bears 2.2/2/2 ventral spines (Fig. 335, c, g). Immovable finger of chelicerae with 2 anterior teeth in front of the median tooth and movable finger with 1 medial cheek tooth next to the main tooth (Fig. 337, c ).]

 

 


Muma (1986) stated the following about Ammotrechella:


"Roewer's (1934) leg, tarsal, spine-like, setal formulae for this genus are 1,2,2,1 for legs 2 and 3 and 2,2-2-2 for leg 4. These species have a mesal tooth on the movable cheliceral finger and 2 primary teeth distad of the principal tooth of the fixed cheliceral finger. Males of this genus often carry remnants of the female dorsal carina on the fixed cheliceral finger with very little additional modification."


Muma (1986) noted:


"Roewer's (1934) leg tarsal spine-like setal formulae for this genus are 1, 2, 2, 1 for legs 2 and 3 and 2, 2-2-2, 1 for leg 4. These species have a mesal tooth on the movable cheliceral finger, and an intermediate and two primary teeth distad of the principal tooth of the fixed cheliceral finger. Except for a distinct to indistinct dorsal indentation, the male fixed cheliceral finger is unmodified."
