description: <i>Solomonius viatorius</i> sp. nov. (Figs. 29E, 32 G-I, 34E, 35B, 36K, 38) <i>Holotype.</i> <b>SOLOMON ISLANDS: Kolombangara</b>, [no specific locality given], 6 June 1922, coll. E. Armytage. Deposited in British Museum of Natural History. <i>Diagnosis.</i> Testaceous to pale olivaceous with dark sometimes metallic markings. Labium reaching sixth abdominal sternite (fifth visible). Profemora with ventral and dorsal series of tubercles. Ventral rim of pygophore with median bilobed process. Medial penile plates distally with small median carina and 2.4x longer than broad. Eighth gonocoxae of female with deeply emarginate posterior margin. <i>Description.</i> Body 2X longer than broad (Fig. 29E). 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 rounded to truncate; posterior margin slightly concave. Scutellum with lateral margins changing angle but not becoming parallel. Bucculae with anteroventral angle acute, produced dorsally and acute, produced anteriorly. Labium reaching sixth abdominal sternite (fifth visible); ratios of labial segments 1:1.7:1.8:1. Peritreme less than 1/2 as long as distance from ostiole of metathoracic scent gland to lateral margin of metapleuron. Episternal ridge located 5/7 of distance between ostiole of metathoracic scent gland and lateral margin of metapleuron. Third through sixth abdominal sternites (second through fifth visible) sulcate. Profemora with ventral row of small stout tubercles; dorsal surface armed with small stout tubercles. Meso- and metafemora with row of small ventral tubercles. <i>Color.</i> Ground color testaceous to pale olivaceous with black to metallic markings and punctations. Antennal segment I straminous; segments II–V with distal half castaneous. Pronotum marked with four dark triangular maculations on the posterior margin. Scutellar bulge with dark maculations on posterolateral portion; anterolateral excavations black; median longitudinal ridge straminous with lateral dark maculations. Forewing with mottling of ground color and darker maculations; membrane testaceous. Labium straminous to testaceous, apical portion of labial segment IV castaneous. Legs of ground color; tubercles or profemora castaneous; tarsi distally and ventrally dark. Venter of abdomen with lateral markings forming a wide continuous castaneous band; medial area straminous. <i>Male.</i> Pygophore constricted around bases of dorsolateral lobes (Fig. 32G–I). Ventral rim with median bilobed process (Fig. 32G). Anterior flange of dorsolateral lobes auriculate, posterior margin rounded with concavity oriented ectad (Fig. 32H, I); posterior lobes absent; posteroventral lobes acute, apically rounded, directed laterally (Fig. 32G–I). Medial penile plates 2.4X longer than broad; distal tip with small medial carina (Fig. 34E). <i>Female.</i> Laterotergites of eighth segment with small pair of blunt lobes. Gonocoxa of eighth segment deeply emarginate medially, anterior and lateral portions sometimes covered by seventh sternite (sixth visible), making gonocoxa appear as narrow fingerlike lobes. Gonocoxa of ninth segment narrow; posterior margin entire to slightly emarginate. Laterotergites of ninth segment appearing relatively elongate because of emargination of gonocoxa of eighth segment; apex subtriangular, rounded (Fig. 36K). Secondary thickening of vagina intima tubular, 3–4X longer than broad, compressed, pore to ductus recepticali opening at apex (Fig. 35B). <i>Measurements.</i> Males (n=8): body length 16.4 SD 0.4 (15.6–17.1), anterior pronotal width 4.0 SD &lt;0.1 (3.9–4.2), humeral width 8.2 SD 0.3 (7.6–8.6), scutellar length 5.9 SD 0.4 (5.2–6.4), medial length of sixth sternite (fifth visible) 1.0 SD 0.1 (0.9–1.2), medial length of seventh sternite (sixth visible) 2.7 SD 0.2 (2.4– 3.0). Females (n=5): body length 16.5 SD 0.9 (15.5–17.9), anterior pronotal width 4.1 SD &lt;0.1 (4.1–4.3), humeral width 8.3 SD 0.3 (7.9–8.9), scutellar length 5.8 SD 0.3 (5.5–6.3), medial length of sixth sternite (fifth visible) 1.5 SD 0.2 (1.3–1.9), medial length of seventh sternite (sixth visible) 2.3 SD 0.1 (2.2–2.7). Appendages in Table 5. <i>Variation.</i> Venter of abdomen sometimes with lateral markings forming an undulating castaneous stripe joining the spiracles. <i>Etymology.</i> From the Latin word <i>viatorius —</i> of or belonging to a journey; reflecting the broad distribution of this species within the New Georgia Group in the Solomon Islands. <i>Paratypes.</i> <b>SOLOMON ISLANDS:</b> 10 May 1922 - 1 &amp;male; (BMNH); <b>Gizo Island</b>, [8° 6' S, 156° 51’ E], - 1 &amp;male; (AMNH); same locality, 21 August 1963, coll.
