Polymorphs with number of elytral
spots varying from few to 13 spots, commonly six along with one spot on the mid-dorsal line of junction of elytra near the scutellum (Fig.
Moreover, Podagricomela with widely placed antennal sockets, closed procoxal cavities, and regularly punctate striate elytra is morphologically unrelated to Hemipyxis having closely placed antennal sockets, open procoxal cavities, and confused, fine elytral
Diagnosis: There are thirteen elytra with the first pair largest and the remainder small button-like discs that are often mistaken as elytral
Shiny, anterior border rectangular and pubescent; humeri fully pubescent; epipleura pubescent until the level of the first abdominal tergite; elytral
striae with marked rounded punctures in lateral striae and weak rounded punctures in dorsal striae.
Compound microstructures and wax layer of beetle elytral
surfaces and their influence on wetting properties.
Acratus is considered a genus between the Ithystenini and the Nemocephalini (SOARES, 1970); it differs from slender Proteramocerus and Teramocerus by the sturdy body (except Acratus apicalis); the head and rostrum are shorter than either Proteramocerus or Teramocerus; the prothorax is pyriform or cylindrical, sulcate; the elytral
apex is rounded; the first tarsal segment is almost as long as the length of 2nd and 3rd together.
The most important non-genitalic characters defining these taxa were elytral
punctation density and metacoxal punctation density.
The relationship of pronotal patterns to elytral
patterns in females was different than in males.
A species with remarkable sexual dimorphism, including entire (not bispinous) elytral
apices in males.
monalisa seen at Khor al-Beidhah (including the sexually active individuals) showed colouration consistent with the two earlier UAE records: the head and thorax were mostly a metallic copper colour, rimmed with green, and the elytral
markings were more or less black (Fig.
costae poorly developed or absent; body setae white 2
The brown speckle within the yellow elytral
stripe is much finer and less obvious than in robertsi.
