Paratypes: 1 male (CNANT0186), 1 female (CNANT0187) deposited in CNAN, 1 female (CAAMS-PS001), 7 tritonymph, 2 deutonymph, and 1 protonymph, with same data as holotype (CNAN).
Nymphs: Much like adults, but trichobothrial patterns as follows: tritonymph with 14 on fixed finger and 8 on movable finger; deutonymph with 9 on fixed finger and 6 on movable finger; and protonymph with 3 on fixed finger and 1 on movable finger.
This undescribed species is known only from 23 specimens (1 [male], 3 [female][female], 11 TT, 5 DD, 3 PP) collected in four of the five nests sampled; however, all specimens were on the "cover" of the nests except for one tritonymph found in the "green chamber".
boneti (1 larva, 1 tritonymph and 2 adult males) stored in ethanol (70%) were dehydrated in graded ethanols, critical-point dried and coated with gold-palladium.
Semeiochernes armiger (Balzan 1892): 6 males collected in January 2006 either as adults (n = 3) or as tritonymphs that molted to the adult stage in the laboratory (n = 3).
