Maracazercon Fain 1989

Maracazeron Fain 1989: 148

[type species: Maracazeron joliveti Fain 1989 , by original designation].

Diagnosis. Distance from setae hyp3 to sc distinctly smaller than distance from hyp3 to hyp2 (21.0); platelets of sternal setae st2 and st 3 in male completely fused (51); endopodal and sternitiventral shield in male fused (58, shared with Afroheterozercon ); postanal seta less than 1/3 the length of paranal setae (73); marginal opisthosomal setae hook-like spines (78, shared with Heterozercon ); femora II setae al, pl, and av in male spines (105–107, shared with Heterozercon and Allozercon ); setae pl1 on tarsi II spine-like (111; shared with Ecuazercon , Amheterozercon , Heterozercon ).

Remarks. The above diagnosis adds some characteristics of the leg setation to Fain’s (1989) diagnosis. This genus shares with Afroheterozercon the fusion of the endopodal and sternitiventral shields in the male, but differs from that genus by the lack of fusion between the metapodal and sternitiventral shields (58, 59). The resulting pattern of the male ventral shields is unique among Heterozerconidae .
