Prosternum punctate on disc, without impunctate
Clypeus almost entirely densely and evenly punctate with only extreme lower margin impunctate
An essential difference is the punctate shell structure of Kinnella compared to the impunctate
structure of Sigmelasma.
Tergite 1 more or less smooth, very shiny, with scattered, laterally with moderately scattered punctures; tergites 2-4 with basal parts shiny and unshagreened, depressed apical parts with superficial reticular shagreening; punctures distinct and dense, only a narrow zone in front of the depressions with punctures more scattered; depressed apical parts with fine and scattered punctures medially, moderately scattered to moderately dense laterally, with narrow impunctate
Thorax nearly impunctate
, shiny; pubescence yellow, shorter than that on head.
Scutellum: Medial swelling well elevated, impunctate
Mesoscutum nearly impunctate
, pubescence similar to that on vertex.
Corium and clavus thickset with pit-like punctures, embolium and cuneus impunctate
Head: malar space less than quarter the width of base of mandible; clypeus with median apical rim and adjacent subapical area without distinct punctures, apical third of clypeus shallowly but distinctly impressed, sides of clypeus with 3 convergent striae composed of a few large elongate punctures separated by narrow impunctate
shining interstriae; facial fovea deep and wide above, extending to level halfway up lateral ocelli, upper margins of foveae sharply margined, not evenly intergrading with occiput, apically wider than antennal width at second flagellar segment.
DIAGNOSIS: Randallophorus is distinguished from other Pilophorini by the broad impunctate
head; the strongly campanulate or bell-shaped, impunctate
pronotum, with a large quadrate velvety spot on each callus; the slender subparallel body; the slender antennae; the scattered whitish, scalelike setae on the dorsum, ventrally on the pro-, meso-, and metapleura areas, abdomen, and ar the bases of the coxae; the simple ostiolar auricle with a wide scent channel lacking a distinct knob dorsally; and the simple, S-shaped endosoma lacking an apparent secondary gonopore.
Mentum widely concave, impunctate
, with scarce, slender setae at sides, anterior border broadly notched.
TEXTURE: Body impunctate
, polished, callosite region of pronotum, corium and abdominal terga weakly shagreened.
