McQuillan. Deposited in The Natural History Museum - London. <i>Diagnosis.</i> Testaceous to pale olivaceous with dark markings. Labium reaching sixth abdominal sternite (fifth visible). Profemora with ventral and dorsal series of tubercles. Ventral rim of pygophore with broadly bilobed process. Medial penile plates medially carinate and swollen apically and 2x longer than broad. Eighth gonocoxae of female with posterior margin extremely sinuate. <i>Description</i>. Body 2X longer than broad (Fig. 29B). 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 an acute angle; posterior margin slightly concave. Scutellum with lateral margins changing angle but not becoming parallel. Bucculae with anteroventral angle acute, produced anteriorly. Labium reaching sixth abdominal sternite (fifth visible); ratios of labial segments 1:1.7:1.9:1. Peritreme less than 1/2 as long as distance from ostiole of metathoracic scent gland of metathoracic scent gland to lateral margin of metapleuron. Episternal ridge 2/3 of distance between ostiole of metathoracic scent gland of metathoracic scent gland and lateral margin of metapleuron. Third through sixth abdominal sternites (second through fifth visible) sulcate. Profemora with ventral row of stout distally hooked spines; dorsal surface armed with small stout tubercles. Mesofemora with row of small ventral tubercles. Metafemora with row of small ventral tubercles. <i>Color.</i> Ground color testaceous to pale olivaceous with castaneous markings and punctations. Antennal segment I straminous; segment II dorsolaterally testaceous; segments III–V with distal half castaneous. Pronotum marked with four dark triangular maculations on the posterior margin. Scutellar bulge with dark maculations on the 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. Tibiae with postmedial dark band; tarsi distally and ventrally dark. Venter of abdomen with lateral markings forming a wide continuous castaneous band; medial area with wide longitudinal castaneous band, labial sulcus of ground color. <i>Male.</i> Pygophore slightly constricted dorsolaterally around bases of dorsolateral lobes (Fig. 30G–I). Ventral rim with median broadly bilobed process (Fig. 30G). Anterior flange of dorsolateral lobe poorly developed as small rounded carina (Fig. 30I); posterior lobes absent; posteroventral lobes acute, rounded, directed laterally (Fig. 30G–I). Medial penile plates little more than 2X longer than broad; basal half or medial area carinate; distal portion slightly swollen with small medial carina (Fig. 33C). <i>Female.</i> Laterotergites of eighth segment with small pair of lobes. Posterior margin of gonocoxa of eighth segment extremely sinuate. Gonocoxa of ninth segment narrow; posterior margin distinctly emarginate. Laterotergites of ninth segment elongate, triangular apically (Fig. 36C). Secondary thickening of vagina intima short, 1.5–2X longer than broad, broadly bilobed distally, pore to ductus recepticali opening between lobes (Fig. 35A). <i>Measurements.</i> Males (n=5): body length 15.7 SD 0.4 (15.1–16.4), anterior pronotal width 3.8 SD 0.1 (3.6–4.1), humeral width 7.9 SD 0.1 (7.8–8.2), scutellar length 5.5 SD 0.1 (5.4–5.7), medial length of sixth sternite (fifth visible) 0.8 SD 0.1 (0.7–1.0), medial length of seventh sternite (sixth visible) 2.7 SD 0.1 (2.6– 3.0). Females (n=5): body length 16.6 SD 0.3 (16.2–17.1), anterior pronotal width 4 SD 0.1 (3.9–4.2), humeral width 8.5 SD 0.2 (8.2–8.9), scutellar length 6 SD 0.1 (5.9–6.2), medial length of sixth sternite (fifth visible) 1.4 SD 0.2 (1.2–1.8), medial length of seventh sternite (sixth visible) 2.3 SD 0.1 (2.2–2.6).
