Paratype
: same data as
holotype
(6).
Diagnosis
. This species can be characterized by: a broadly obtusely angled cuticle between pronotal anterior setal tufts (
Fig. 27
); male genitalia with expanded posterior portion of parameres,and elongate median lobe (Fig. 35).
Description
. Body reddish brown to brown; body oval, convex. Length
1.5–1.8 mm
. Head dorsally smooth but with scattered setose tubercles in a band between eyes, tubercles distinct; setae short, recumbent and erect; setal tufts on either side of midline between eyes present; carina posterior of antennal fossae absent. Pronotum with visible surface extending posteriorly between setal tufts broadly triangular, forming an obtuse angle posteriorly; base of setal tufts arising from just slightly above cuticular surface by height equal to that of tubercles on curved carinae, anterior margin swollen, especially at middle; lateral spines distinct from but blending into tufts, thickness similar to erect elytral setae. Elytral surface moderately convex, apices rounded, not projecting; erect setae yellow, moderately long; six round patches of slightly flattened recumbent white setae located anteriorly within puncture rows 5–8 and posteriorly within rows 4 and 8. Male genitalia with parameres thinnest near apical 1/3, strongly curved inwards near apex, apices distinctly expanded; median lobe parallel sided except near apex, total length 87% of that of parameres measured from base (Fig. 35).
