''Aptostichus bonoi'', or Bono's Joshua Tree trapdoor spider, is a morphological species of Euctenizidae spiders,
Unlike males of the rest of the '' Aptostichus'' species, male specimens of ''A. bonoi'' and '' A. fisheri'' barely have scopula pads and possess short but distinctive spines on the ventral surface of tarsus I. The two species differ in that ''A. bonoi'' has significantly more spines on the retrolateral surface of tibia I. ''A. bonoi'' is one of only two

Description
Unlike males of the rest of the '' Aptostichus'' species, male specimens of ''A. bonoi'' and '' A. fisheri'' barely have scopula pads and possess short but distinctive spines on the ventral surface of tarsus I. The two species differ in that ''A. bonoi'' has significantly more spines on the retrolateral surface of tibia I. ''A. bonoi'' is one of only two sympatric species
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species s ...
of ''Aptostichus'', the other one being '' A. serrano''. The two species are easily distinguished from one another due by spines on the retrolateral surface I, which ''A. serrano'' lacks.
''Aptostichus bonoi'' was described on the basis of only one male and one female type specimen; the male is the holotype and is presumed to have been collected from a pitfall trap, while the female is the paratype and was presumably caught live in her burrow. The species is known only from an area of Joshua Tree National Park called Covington Flat, which is the type locality. The available data is very limited, but it is assumed that males disperse to look for females from late fall until early winter.
Conservation status
Due to the very limited range of the species and its scarceness in collections, it is probable that Bono's Joshua Tree trapdoor spider is endangered in terms of its conservation status. According to Bond, the protection of the species is critical.See also
