Solomonius viridula ( Distant, 1899) comb. nov.

(Figs, 28I, 32J-L, 34F, 36L, 38)

Dalpada viridula Distant, 1899: 427 ; Bergroth, 1908: 154 (listed); Kirkaldy, 1909: 194 (listed)

Diagnosis. Metallic green to bronze with some straminous and testaceous markings. Labium reaching fifth abdominal sternite (fourth visible). Profemora with ventral series of tubercles. Ventral rim of pygophore with narrowly bilobed process. Medial penile plates distally swollen with small median carina and 2x longer than broad. Eighth gonocoxae of female broadly subtriangular.

Redescription. Body 2X longer than broad ( Fig. 28I View FIGURE 28 ). Head broader than long; juga shorter than tylus. Pronotum with anterior margin linear becoming concave medially; anterolateral angle produced laterally as small tubercle; anterolateral margins subentire (some vague crenulations anteriorly), explanate; lateral angles produced into acute angle; posterior margin slightly concave. Scutellum with lateral margins becoming briefly parallel prior to apex. Bucculae with anteroventral angle rounded and acute, produced anteriorly. Labium reaching fifth abdominal sternite (fourth visible); ratios of labial segments 1:1.7:1.6:1. Peritreme less than 1/2 as long as distance from ostiole of metathoracic scent gland to lateral margin of metapleuron. Episternal ridge located 2/3 of distance between ostiole of metathoracic scent gland and lateral margin of metapleuron. Third through fifth abdominal sternites (second through fourth visible) sulcate. Profemora with ventral row of stout distally hooked spines or small stout tubercles; dorsal surface unarmed. Mesofemora with row of small ventral tubercles. Metafemora with row of small ventral tubercles.

Color. Ground color bronze with some straminous and testaceous areas. Antennal segments I–III castaneous; segments IV–V with distal half castaneous. Pronotum almost entirely bronze. Scutellar bulge of ground color; anterolateral excavations black; median longitudinal ridge straminous. Forewing primarily of the ground color, sometimes with straminous proximal and distal areas; membrane testaceous. Labium straminous to testaceous, apical portion of labial segment IV castaneous. Legs testaceous with castaneous speckling; tubercles or profemora castaneous. Tibiae uniformly castaneous; tarsi distally and ventrally dark. Venter of abdomen with lateral markings forming a wide continuous castaneous band; medial area testaceous medially.

Male. Pygophore constricted around bases of dorsolateral lobes ( Fig. 32J–L View FIGURE 32 ). Ventral rim with median narrowly bilobed process ( Fig. 32J View FIGURE 32 ). Anterior flange of dorsolateral lobes developed as small rounded carina, convexity directed dorsally ( Fig. 32K, L View FIGURE 32 ); posterior lobes present, rounded, directed entad; posteroventral lobes narrowly acute, directed anterolaterally ( Fig. 32J–L View FIGURE 32 ). Medial penile plates little more than 2X longer than broad; distal portion slightly swollen with small medial carina ( Fig. 34F View FIGURE 34 ).

Female. Laterotergites of eighth segment broad with small pair of lobes. Gonocoxa of eighth segment broadly subtriangular, exposing all of gonocoxa of ninth segment. Gonocoxa of ninth segment broad; posterior margin distinctly emarginate. Laterotergites of ninth segment broad with undulate anterolateral carina, triangular apically. Gonopophyses of ninth segment with small median pore of unknown homology located between scrotumlike lobes of gonocoxa of ninth segment ( Fig. 36L View FIGURE 36 ). Secondary thickening of vagina intima short, as long as broad, distally bilobed, pore to ductus recepticali opening in distal emargination.

Distribution. Bougainville and Shortlands Islands ( Fig. 38 View FIGURE 38 ).

Comments. As it possesses reduced parameres which are fused with the proctiger, as well as elongate median penile plates which are fused together, Dalpada viridula is transferred to Solomonius . The remaining species of the genus Dalpada Amyot and Serville possess relatively well-developed claspers which are free from the proctiger, and therefore those species remain in that genus.
