description: Solomonius n. gen.   
 Description. Head with antennifers visible from above; vertex convex. Juga separated anteriorly, rounded and obtuse apically. Antennae 5-segmented; antennal segment 1 surpassing apex of head. Eyes slightly stalked. Ocelli located posterior of imaginary line drawn through posterior margins of eyes. Pronotum distinctly hexagonal; anterolateral margins slightly sinuate. Scutellum subtriangular, basally slightly swollen, with a narrow longitudinal raised area along median. Wings reaching or slightly surpassing end of abdomen. Laterotergites visible from above.   
Bucculae posterior margin acuminate. Prosternum sulcate; anterior margin concave; posterior margin of prosternum not reaching posterior margin of first coxal cavity. Mesosternum slightly sulcate with low median keel; posterior margin bilobed; posterolateral angle of mesopleuron posteriorly produced as narrow lobe. Metasternum hexagonal; lateral margins swollen between second and third coxal cavities; posterolateral angle of metapleuron entire; ostiole of metathoracic scent gland lenticulate; peritreme of equal breadth throughout its length, rounded distally. Abdomen medially flattened, sometimes sulcate; trichobothria transverse, coincident with spiracular line, on or just posterior to pseudosuture. Posterior margin of sixth abdominal sternite (fifth visible) distinctly “V”-shaped in males, less so in females. Legs with profemora with tubercles, stout spines, or unarmed; meso- and metafemora with tubercles or unarmed.  
 Male. Pygophore subglobular with elongate posteriorly directed dorsolateral lobes; ventral margin variable. Dorsolateral lobes longer than chamber portion of pygophore, often lobed posteriorly and/or anterodorsally. Proctiger heavily sclerotized, broadly ovoid globular; anus apical. Basal sclerite of proctiger well developed, fused with reduced parameres. Medial penile plates of aedeagus fused, equal to or longer than phallotheca.   
 Female. Posterior margin of abdominal seventh sternite (sixth visible) deeply emarginate medially. Gonocoxa of eighth segment variable. Gonocoxa of ninth segment with large lateral scrotum-like lobes. Laterotergites of ninth segment elongate, apically triangular, surpassing posterior margin of abdominal tergite VII. Secondary thickening of vagina intima tubular (Fig. 35A), sometimes bilobed distally (Fig. 35B), surrounding pore to ductus recepticali.   
 Etymology. A latinized form of the proper noun Solomon in reference to the Solomon Islands in which this genus is quite diverse. The genus name should be considered male in gender.   
 Type species. Solomonius malaitaensis sp. nov.   
 Comments. Member of the genus Solomonius are relatively large for the Solomonius -group. The male genitalia are distinctive in possessing elongate, robust, dorsolateral lobes. This is the only genus in the Solomonius -group in which the medial penile plates of the aedeagus are elongate and protrude outside of the genital capsule. Species in this genus can be distinguished from one another with the following key.
