( Fig. 54 )

Diagnosis. Setae chb absent. Setae v 2 and sc 1 vestigial. Setae c 1 absent. Dorsal idiosomal setae not thickened basally. At least prodorsal shield and hysterosomal tergites C and D with distinct subcuticular reticulation. Setae (pl) on tarsus I, (tc) on tarsi II and III, and tc’ on tarsus IV spatulate distally. Two pairs of aggenital setae. Apodemes 5 short.

Material examined. Four females, date, locality and collector unknown. All specimens are deposited in the collection of the Tyumen State University Museum of Zoology , Tyumen, Russia .

Remarks. This species was described from Honduras ( Lindquist et al. 1990) from the beetle Neoathyreus mexicanus . It was also recorded from Costa Rica from Neoathyreus tridentus ; El Salvador from N. mexicanus ; Honduras from N. cf. excavatus ; Guatemala from N. interruptus and N. mexicanus ; and Mexico from N. interruptus ( Lindquist et al. 1990) .
