DIAGNOSIS
The genus is easily separable from all other genera of Cydnidae in having strongly swollen pronotal umbones concealing posterolateral margins of pronotum (Figs 3­4), apex of peritreme with more or less blunt triangular lobe posteriorly (Fig. 6), and head submargins bearing only hair­like setae (Figs 1­2), entirely without pegs or peg­like setae.
DESCRIPTION
B o d y. More or less ovate, from 4.7 to 12.7 mm in length, and 2.7 to 6.7 mm in width; general appearance as in Figs 99, 143 and 279.
H e a d. Broadly rounded, margins carinate; dorsal surface more or less punctate; clypeus free, usually parallel­sided, sometimes slightly tapering apicad, with or without a pair of subapical hair­like setae; each paraclypeus with two (M. lobatus) or three (all other species) primary hair­like setae (Fig. 1), submarginally without or with 1­10 secondary hair­like setae (Fig. 2); eyes large, more or less protruding, almost triangular (Fig. 1), or narrowed (Fig. 2), each bearing a single very short apical seta, about third or fourth eye length (Figs 1­2); ocelli clearly visible; bucculae large, entirely coarsely punctate or impunctate in anterior part; rostrum 4­segmented; antennae 5­segmented.
P r o t h o r a x. Pronotum broader than long, more or less narrowed apically; anterior margin angularly insinuated, disc usually punctate anteriorly, laterally, and behind its middle, transverse discal impression behind calli from absent to distinctly developed; lateral margins with submarginal setigerous punctures (absent only in M. lobatus), pronotal disc with three primary setigerous punctures bearing long hair­like setae (absent only in M. lobatus); umbones strongly swollen and protruding caudolaterally, concealing posterolateral margins (Figs 3­4); pronotal disc usually more or less unicolorous, in some species sharply bicoloured with umbones and/or posterior margin yellow or yellowish brown. Prosternal median carina low, basally stout, coarsely punctate; subcarinal smooth areas large and clearly visible; median part of posterior margin of prosternum straight or almost straight, sometimes bearing small triangular process; propleural depression deep and coarsely punctate; anterior and posterior convexities of propleuron distinctly developed.
M e s o t h o r a x. Scutellum triangular, longer than broad, sharpened apically; basal and lateral rows of punctures clearly developed, punctures in rows usually connected by incised lines; disc more or less punctate. Posterior wedge­shaped polished band on mesopleural evaporatorium well developed, impunctate or punctate; mesopleural evaporatorium large, occupying almost entire mesopleural surface, bearing more or less clearly visible longitudinal ridges (Fig. 5).
M e t a t h o r a x. Corium divided into clavus, meso­ and exocorium; clavus usually with one complete and one or two incomplete rows of punctures; mesocorium entirely separated from exocorium, with two rows of punctures parallelling clavo­corial suture; costa from entirely separated to entirely fused with exocorium, either with or without setigerous punctures; membrane normally developed, large; membranal suture more or less bisinuate. Metapleural evaporative areas large, bearing more or less clearly visible longitudinal ridges (Fig. 5); apex of peritreme rounded, its anterior margin clearly differentiated from evaporatorium surface or prolonged to fuse with it, its posterior margin with more or less blunt triangular lobe (Fig. 6); scent gland opening large, clearly visible, placed posteriorly on peritreme; posterior area of metapleuron with broader or narrower band of coarse punctures.
L e g s. More or less unicolorous, in some species femora bicoloured, yellow or yellowish brown with median dark stripe; fore tibiae expanded apically, margins armed with spines; male hind femora usually with one subapical tooth on dorsal margin, and several more less distinct teeth or spines on ventral margin; female hind femora with or without small subapical tooth on dorsal margin, and several setae on ventral margin; hind tibiae slender, basally more or less reflected and usually with tubercles or carinae in males.
A b d o m e n. Sterna from almost impunctate to distinctly punctate and wrinkled, usually with at least patch of tiny punctures close to spiracles; terga impunctate or punctate, always pilose. Male and female genitalia of the common geotomine type.
