In these beetles, the testes are tubular and the first abdominal sternum ( a plate of the exoskeleton ) is divided by the hind coxae ( the basal joints of the beetle's legs ).

Adult crawling water beetles use both their elytra and their hind coxae ( the basal segment of the back legs ) in air retention, while whirligig beetles simply carry an air bubble down with them whenever they dive.
33.
In almost all Riodinidae, the coxae of the front legs are extended on males jutting out over the trochanter ( only hinted at in " Styx infernalis " and " Corrachia leucoplaga " ).
34.
Males lack this particular furrow, so the mites are found on the smooth, concave ventral surface of the thorax between the coxae . " H . sexcinctus " was also found to harbor mites of the families Pygmephoridae and Scutacaridae " ."
35.
""'Charletonia austisensis " "'is a species of mite belonging to the family Erythraeidae . " C . austisensis " belongs to the species group with two setae between coxae II and III . It differs from its cogenerate species by various length measurements.
36.
Underneath the carapace is the mouth and six appendages, usually referred to in Roman numerals I-VI . Each appendage in turn is composed of nine segments ( known as podomeres ) labeled in Arabic numerals 1-9 . The first segments which connect the appendages to the body are known as the coxa ( plural coxae ).
37.
""'Charletonia cuglierensis " "'is a species of mite belonging to the family Erythraeidae, so named after its type locality . " C . cuglierensis " belongs to the group of species which possess two setae between coxae II and III . It differs from its cogenerate species by length measurements.
38.
The "'hip joint "', scientifically referred to as the "'acetabulofemoral joint "'( " art . coxae " ), is the joint between the femur and acetabulum of the pelvis and its primary function is to support the weight of the body in both static ( e . g . standing ) and dynamic ( e . g . walking or running ) postures.
39.
Head white tinged with buff; palpi crimson at base, black at tips; frons at sides and antennae black; thorax brown buff, the patagia with black spots; pectus dark brown in front; crimson streaks below the wings; the fore coxae and femora above crimson, the tibiae and tarsi black above; abdomen crimson, the base, tip of anal tuft and ventral surface buff, a dorsal series of black bands except at base, lateral series of spots and sublateral spots on medial segments.
40.
All 3 species have long, narrow, tapering auriculae ( lateral protrusions found on the ventral surface of their basis capituli, an apical region that is formed by the basal portions of their 2 pedipalps ) and several unique structure on their coxae ( the most basal of the several segments that constitute each of their legs ), including internal spurs on their first pair of coxae ( coxae I ); small but distinct external spurs on their first pair of coxae ( coxae I ); and syncoxae ( posterior regions that have a lighter color or texture ) on their first, second, and third pairs of coxae ( coxae I-III ).
