Etymology. Formed from the Latin words longus (long) and petiolus (stalk) in reference to its comparatively long petiole.

Description. FEMALE ( Fig. 37 ). Length about 2.5–3.5 mm. Head in frontal view ( Fig. 39 ) with face and frontovertex green with variably distinct coppery to reddish-violaceous lusters under some angles of light; frontovertex distinctly differentiated by difference in sculpture at level about midway between toruli and anterior ocellus, with larger, shallower, more isodiametric reticulation dorsad level compared to much smaller, more transversely punctate-reticulate sculpture ventrad level; in lateral view lower face and gena posterior to malar sulcus similarly strongly sculptured and colored; in dorsal view OOL about 2.25–2.5× maximum diameter of posterior ocellus. Antenna ( Fig. 43 ) yellow or pedicel and/or fl1 sometimes slightly brownish; fl1slightly transverse, fl4 about 0.8× length of fl2 and fl3, and funiculars increasing in width and beyond fl4 decreasing in length such that apical funicular slightly transverse in dorsal view; apical funicular ventrally extending under clava as apically tapered, ventrally sparsely setose, finger-like projection to level where clava tapers into terminal, setose, ventrally curved finger-like process. Mandible indistinctly tridentate, the ventral two teeth more acutely angled.

Pronotal collar ( Fig. 38 ) in lateral view flat but in dorsal view with abruptly declivitous concave regions posterolaterally such that pronotum appears more or less "shoulder-like" on either side; dorsally punctulatereticulate and mostly green with variably distinct coppery luster except neck more brownish and much more finely sculptured and shinier posterolateral declivitous regions partly reddish-violaceous to more blue posteriorly and often green laterally where more distinctly meshlike coriaceous, with each region having line of obvious white setae along lateral margin and transversely across region behind transverse anterior margins that together delineate posterior margin of broadly V-like convergent dorsal sculptured region. Mesoscutum ( Fig. 38 ) anteromesally between incomplete notauli similarly punctulate-reticulate as pronotum dorsally, but posteriorly and on lateral lobes with larger mesh-like reticulations and with variably bright and distinct coppery luster and usually with at least some reddish-violaceous luster anteriad axillae; scutellar-axillar complex ( Figs 38, 40 ) similarly colored as mesoscutum, axilla with slender dorsal reticulate surface less than length of median crenulate region between axillae, and with obliquely angled posterior surface mostly meshlike coriaceous to smooth, and scutellum convex, reticulate-punctate dorsally but more reticulate to reticulate-imbricate laterally and posteriorly, the dorsal sculpture intermediate in size between anteriorly and posteriorly on mesoscutum Tegula brown. Macropterous; fore wing ( Fig. 44 ) marginal vein about 8.0–9.4× length of stigmal vein; postmarginal vein extending to or slightly beyond level of uncus; uncus ( Fig. 45 ) diverging from stigmal vein apically so distinct stigma not differentiated and apex separated from posterior margin of postmarginal vein by distance distinctly less than width of postmarginal vein or maximum height of stigma plus uncus; costal cell ventrally with 0–3 setae basally; disc ( Fig. 44 ) with large brown region behind somewhat more than apical half of venation extending width of wing except for hyaline medial fold, and sometimes also with very small and inconspicuous lighter brownish region behind parastigma, with brown setae in infuscate regions and shorter, less conspicuous setae apically, except bare behind parastigma and marginal vein basally, the bare region conspicuously expanded posteriorly behind marginal vein adjacent to infuscate region, and dorsally with comparatively large, elongate bare region beyond stigmal vein ( Fig. 45 ); marginal fringe present except anteroapically beyond postmarginal vein ( Fig. 45 ). Prepectus mostly bare but usually with a few short, inconspicuous white setae posteroapically. Mesepimeron variably setose along posterior margin, sometimes with line of short white setae along entire margin ( Fig. 41 ) but with at least one seta within dorsal half (upper mesepimeron) and lower half (lower mesepimeron). Metapleuron ( Fig. 41 ) mesh-like reticulate ventrally and much shallower coriaceous-reticulate dorsally, and with sparse white setae anteroventrally and dorsally and posteriorly in more finely sculptured region. Metasternum comparatively short, with bases of meso- and metacoxae about on same level and apex of mesocoxa projecting conspicuously beyond base of metacoxa. Legs ( Fig. 37 ) with procoxa orangey-brown to brown or sometimes with reddish-violaceous luster, mesocoxa usually somewhat darker brown and with some metallic luster, and metacoxa yellowish ventrally; femora, tibiae and tarsi brown to yellowishbrown except basal three or four tarsomeres of meso- and metacoxae more yellowish compared to darker brown apical tarsomeres; metacoxa bare dorsally ( Fig. 42 ). Propodeum ( Fig. 42 ) with crenulate band along anterior margin recurved posteromedially into narrowly V-shaped crenulate band on either side of complete median carina; panels otherwise reticulate except for comparatively small smooth and shiny region anteromesally on either side of median sculptured region, and multicolored with anterior crenulate band greenish and depending on angles of light panels variably extensively reddish-violaceous anteriorly to greenish or somewhat coppery laterally and blue to purple posteriorly; callus finely coriaceous and multicolored similar to panels.

Petiole ( Fig. 42 ) yellow to yellowish-brown, with sides slightly divergent posteriorly but distinctly oblong, about twice as long as wide. Gaster ( Fig. 37 ) uniformly dark brown; basal two tergites shiny and smooth or with at most effaced mesh-like sculpture and remaining presyntergal tergites isodiametric mesh-like coriaceous except smooth along posterior margins (mesal tergites also smooth along basal margins, but the result of exposure due to gaster being inflated), with Gt2 strongly transverse, much shorter than other tergites, and Gt4 the largest tergite.

MALE ( Figs 46, 47 ). Length = 1.8–2.5 mm. Head ( Fig. 48 ) mostly green but with variably extensive and distinct coppery to reddish-violaceous luster, usually most distinctly on frontovertex and within and/or mesally above scrobes; sculpture of face and frontovertex similar to female or more uniformly mesh-like reticulate. Antenna ( Fig. 49 ) 11-segmented; scape mostly yellow, though sometimes partly brownish dorsally, pedicel yellowish-brown to brown, at least dorsally, and flagellum dark brown except for more yellowish, strongly transverse, anelliform fl1; funiculars all conspicuously longer than wide, pedicellate, and smooth and shiny except for finely, transversely strigose apical pedicel and whorl of long brown setae mesally, with apical-most funiculars uniformly spindle-like and more basal funiculars having convex dorsal and flat ventral surfaces; clava about twice as long as apical funicular, basally expanded and with three successive whorls of setae (two usually distinct). Mandible tridentate with three similar teeth ( Fig. 48 ). Labial and at least apical maxillary palpi white ( Fig. 48 ) and sometimes ventral surfaces of all palpomeres white.

Pronotum ( Figs 47, 48 ) green or with slight coppery luster and punctate-reticulate except usually with somewhat more finely sculptured reddish-violaceous to purple region posterolaterally ( Fig. 48 ). Mesonotum ( Fig. 47 ) green or with variably distinct coppery luster and comparatively uniformly mesh-like reticulate or anteriorly reticulations smaller, more punctate-reticulate similar to pronotum dorsally. Fore wing ( Fig. 50 ) with marginal vein about 6.2–7.8× length of stigmal vein; hyaline; disc obliquely bare behind parastigma and about basal half of marginal vein, and discal setae shorter and more uniform than female. Prepectus and posterior margin of mesepimeron ( Fig. 52 ) bare. Metapleuron ( Fig. 52 ) similarly sculptured and setose as female. Metasternum comparatively short, mesocoxa projecting conspicuously beyond base of metacoxa. Front leg with coxa dark with blue to violaceous luster; femur and tibia dark brown with violaceous luster usually at least on femur under some angles of light, except knee and sometimes tibia apically pale; tarsus yellowish-brown basally to dark brown apically. Middle leg similar in color to front leg except basal three tarsomeres pale. Hind leg with coxa entirely dark with metallic luster, often more blue ventrally and green to reddish-violaceous laterally or dorsally, but otherwise similar in color to middle leg. Propodeum ( Fig. 51 ) with complete median carina; panels entirely meshlike reticulate and usually mostly reddish-violaceous except usually variably blue to greenish anteriorly along crenulate furrow, mesally within crenulate furrow on either side of median carina, and within postspiracular sulcus; callus shiny, virtually smooth and reddish-violaceous.

Petiole ( Figs 51, 52 ) similarly dark as rest of body with blue to purple or green luster, more or less mesh-like coriaceous to reticulate, and about 2.0–2.5× as long as wide.
