basebase:
point or edge closest to the body; opposite of apex
extending to interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
8; body glabrousglabrous:
smooth, devoid of vestiture
except for pronotalpronotal:
pertaining to the pronotum
and elytralelytral:
pertaining to the elytra
bases; striaestria:
punctures in rows, which may or may not be impressed to make grooves
and interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
uniseriate punctatepunctate:
set with fine impressed points, appearing as pin pricks
; elytralelytral:
pertaining to the elytra
discdisc:
the flat central upper surface of any body part (e.g. pronotum and elytra)
strongly shiningshining:
appearing glossy or bright in luster; referring to a surface that is polished and reflects light well
, declivitydeclivity:
downward slope of either the pronotum or elytra
shagreened; declivitydeclivity:
downward slope of either the pronotum or elytra
bisulcatebisulcate:
pertaining to an elytral declivity with two suci; a sulcus present on each elytron but the suture remains convex
, interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
2 to striaestria:
punctures in rows, which may or may not be impressed to make grooves
3 weakly to moderately depressed, interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
4−7 carinate, interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
4 moderately tumescent and sharply carinate from basebase:
point or edge closest to the body; opposite of apex
to apicalapex:
point or edge furthest from the body; opposite of base
half; posterolateralposterolateral:
relating to end of the side part/portion
margin carinate to interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
7; protibiaprotibia:
tibia of the first pair of legs
obliquely triangular; pronotumpronotum:
the dorsal surface of the thorax
rounded, robust (type 5) when viewed laterally, and rounded (type 1) when viewed dorsally.
