KEY TO GENERA OF THE SUBFAMILY ENTOMOBRYINAE SENSU SOTO- ADAMES ET AL. (2008)

WITH SCALES AND DENTAL SPINES

1. Dental scales absent ............................................................................................ Sinhomidia gen. nov. Dental scales present.........................................................................................................................2

2. Body scales all rounded and finely striate; few macrochaetae on dorsal body except collar.............. Acanthurella Body scales mainly pointed and coarsely striate; numerous macrochaetae on whole body.............. Acanthocyrtus

Ant ., antennal segment.

Diagnosis: The genus is characterized by foursegmented antennae, eight + eight eyes, scales on body, scales and spines on dens, clavate tenent hairs on tibiotarsus, bidentate mucro with a basal spine, papillate male genital plate, two–three–two bothriotrichia on Abd. II–IV, respectively, and modified accessory microchaetae of the bothriotrichial complex. Some or most scales are pointed and coarsely striate as is typical for Seirini. It is close to Lepidosira or Lepidocyrtoides in scale morphology, body chaetotaxy, claw, and trochanteral organ morphology but differs in the presence of dental spines.
