Type material
Holotype: Collected near Chaomidian Village , Beipiao City , Liaoning Province, China; the Yixian Formation , Late Jurassic–Early Cretaceous (Late Tithonian to Berriasian), one specimen, part and counterpart of a near complete adult, No. CNU-C-LB2006004-1 and No. CNU-C-LB2006004-2, housed in Key Lab of Insect Evolution and Environment Change, Capital Normal University, Beijing, China.
Description
Body length 10.0 mm; body width 2.5 mm; elytron length 7.0 mm. Medium and subcylindrical beetles, covered with tubercles ( Figure 2A View Figure 2 ).
Head: wider than long, subtriangular, bearing two pairs of tubercles, anterior pair of tubercles at base of antennae, conical, small, posterior ones oblong, larger than anterior pair, ventral surface without groove for inserting antennae; eyes small; temples a little shorter than eyes, projected laterally; mandibles prominent, broad, apex flattened, tridentate ( Figure 2B View Figure 2 ), palpi visible with two segments.
Antennae: filiform, 11 segments, scape thicker and longer than other antennomeres, pedicel shortest, as long as wide, following antennomeres more or less homonomous.
Pronotum: transverse, slightly wider than head, about 1.3 times as wide as long, anterior margin straight, anterior angles bifid, without propleuron, disc of pronotum without elevations, scutellum semicircular.
Elytron: about 1.4 times as wide as prothorax, longitudinal ridges with small tubercles, 4.5 times as long as wide, epipleural rim comparatively wide, with eight rows of cells, elytral cells polygonal, with three black maculae on their margins ( Figure 2D View Figure 2 ), approximately 30 cells formed in a row.
Ventral surface ( Figure 2C View Figure 2 ): gula rectangular, reaching posterior ridge of the head, widening posteriorly, gena widely separated along entire distance ventrally; procoxal cavities at the middle of prosternum, small, separated, prosternal process not extending behind coxae; metasternum trapezoidal, transverse, 1.5 times as long as wide (at posterior margin), with longitudinal and transverse sutures developed on metasternum. Abdomen with five visible ventrites superimposed on each other, narrowed from the base of forth visible ventrite, first visible abdomen ventrite slightly longer than others, two to four visible abdomen ventrites nearly equal in length, last visible ventrite two times as long as the previous one, its apex rounded.
Legs: procoxae rounded, small, protrochanter very small, oblong, profemora shorter than protibiae, protarsi with five segments, first and last tarsomeres equal in length, both of them longer than other ones, two to four tarsomeres short, equal in length; mesocoxae subcircular, mesotrochanter oblong, mesofemora thick, mesotibiae as long as mesofemora; metafemora short, slightly extending beyond side margins of body.
