Diagnosis.
Metallic green with testaceous and red maculations. Labium reaching fourth abdominal sternite (third visible). Profemora with ventral series of tubercles. Ventral rim of pygophore with median bilobed process. Medial penile plates simple and 1.5x longer than broad. Eighth gonocoxae of female subquadrate, posterior margin becoming laterally lobed.
Description
. Body 2X longer than broad (
Fig. 28H
). Head broader than long; juga shorter than the tylus. Pronotum with anterior margin linear, becoming concave medially; anterolateral angle entire; anterolateral margins subentire (some vague crenulations anteriorly), slightly carinate; 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. Labium reaching fourth abdominal sternite (third visible); ratios of labial segments 1:1.7:1.7:1. Peritreme 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 fifth abdominal sternites (second through fourth visible) sulcate. Profemora with ventral row of stout distally hooked spines; dorsal surface unarmed. Mesofemora and metafemora with row of small ventral tubercles; dorsally unarmed.
Color.
Ground color metallic green with testaceous and red maculations. Antennal segments I–II dorsolaterally testaceous; segment III with distal half castaneous; segment IV castaneous; segment V straminous. Pronotum metallic green, red medially. Scutellar bulge with dark maculations on the posterolateral portion; anterolateral excavations black; median longitudinal ridge red. Forewing primarily of ground color; membrane testaceous. Labium straminous to testaceous, apical portion of labial segment IV castaneous. Legs straminous with testaceous speckling; tubercles or profemora castaneous; tibiae with postmedial dark band; tarsi mostly straminous, segments I and III testaceous apically. Venter of abdomen with lateral markings discontinuous, restricted to area surrounding spiracle; medial area straminous.
Male.
Pygophore slightly constricted around bases of dorsolateral lobes (
Fig. 32D–F
). Ventral rim with median bilobed process (
Fig. 32D
). Dorsolateral lobes with anterior flange absent (
Fig. 32E,F
); posterior lobes well developed, rounded, directed entad; posteroventral lobes narrowly acute, directed anterolaterally (
Fig. 32D–F
). Medial penile plates relatively broad for genus, 1.5X longer than broad (
Fig. 34D
).
Female.
Laterotergites of eighth segment broad, lobes obsolete. Gonocoxa of eighth segment subquadrate with low, broad lateral lobe. Gonocoxa of ninth segment broad; posterior margin deeply emarginate. Laterotergites of ninth segment slightly triangular apically (
Fig. 32J
). Secondary thickening of vagina intima subquadrate, semihemispherical, pore to ductus recepticali opening at apex.
