physorhinus Candeze, described from Mexico, with both species appearing similar in appearance and general morphology, including the parallel walls of the mesosternal
fossa and the posterior intercoxal portion of the mesosternum strongly declivous, ca.
Pronotum dorsally cylindrical, slightly convex between sulci 2 to 4 in dorsal view and rugose; laterally, and in the anterior part of the prozona and posterior part of metazona more rugose, slightly tuberculate; anterior and posterior margins of pronotum rounded; prosternai process conical with acute apex; mesosternal
space open with rounded lobes; hind femur 4 to 5 times longer than wide, 4 times longer than the foot and about 2/3 the length of the hind femur of G.
intercoxal process with deeply emarginated posterior margin.
The anatomical sites of participants were marked as acromial, radiale, mid acromial-radiale, subscapular, stylion, mid-stylion, mesosternal
, ill-crystal, illospinale, supraspinal, trochanterion, mid trochanterion-tibial lateral, mid-thigh, tibial lateral, tibial medial and sphyrion.
Foveolae long, trapezoidal reaching at the end of fastigium; mesosternal
interspaces significantly wider than long.............................................
Body shorter, length <10 mm 5 5 Mesosternal
tubercle low, broad, and rounded in profile.
substitullis Short & Perkins, 2004 en tamano, forma y disposicion de los puntos piliferos en los elitros, pero difieren en forma y numero de espinas en el proceso mesosternal
y la capsula genital, aunque en O.
apophysis narrow, facing a sharply rounded frontal apophysis of metasternum.
unicornis the mentum and the mesosternal
scars are glabrous and elytral striae 8-10 are pubsecent to their ends, characters which differentiate it from P.
Prosternai spines are delicate and short (shorter than the clypeus hornlets), mesosternal
lobes are pointed and erected, metasternal ones broadly rounded, and the metasternal pit is transverse, short, and deep (divided by a thin medial ridge).
