Diagnosis

Males of M. pax resemble those of M. acanthaspis comb. nov. and M. ramirezi by the presence of white feathery hairs on the carapace ( Figs 3A, D View Fig , 12A View Fig ), but differ by the tibia I ventral spination being 3-3 (4- 4 in M. ramirezi and 5- 4 in M. acanthaspis comb. nov.) and having the embolus with two keels ( Figs 3I–J View Fig , 6D View Fig ) (absent in both M. ramirezi and M. acanthaspis ). Females of M. pax resemble those of M. kaspari and M. tembe sp. nov. by the tibia I ventral spination being 3-3; they differ from those of M. kaspari by the presence of white feathery hairs on the carapace (absent in M. kaspari ), and from those of M. tembe by the presence of a short groove above the CO ( Fig. 3G View Fig ) (absent in M. tembe ) and by the narrow ST I (nearly ⅓ of ST II width) ( Figs 3H View Fig , 6A View Fig ) (wider, nearly ½ of ST II width in M. tembe ).

Description

See Reiskind (1969: 264).

Remarks

As reported by Reiskind (1969), this species is polymorphic, mainly regarding the extent of feathery hairs on the carapace, coloration, and the length of the DS ( Reiskind 1969). The specimens attributed here to M. pax present the same characteristics as the Costa Rican forms, such as the brown-black color, the dorsal abdominal sclerite ending at an impression, and the extent of feathery setae on the carapace.

Distribution

Mexico to Colombia ( Fig. 20 View Fig ).
