Body. Body length 5-6 mm. Body form moderate or robust. Crown and pronotum at most somewhat convex, not arched above eyes. Anterior margin of head without round black spots. Vermiculate color pattern on wings and sometimes head and body absent. Predominant coloration white or off-white or ochraceous or orange or brown. Bright orange or red coloration absent. Crown with colored maculae, spots, or lines. Anterior margin of head without alternating dark and light transverse stripes.

Head. Head distinctly narrower than pronotum. Crown not produced, apex not longer than 1.5x length next to eye, flat or convex. Discal portion of crown radially or longitudinally striate. Transition of crown to face rounded. Texture of anterior margin of head shagreen. Frontoclypeus moderately narrow, median length 1.25x to 2x width between antennal pits or long and narrow, median length more than 2x width between antennal pits, not widening abruptly dorsad of antennal pits, texture shagreen. Clypellus widening apically, relatively flat. Lorum subequal to or wider than clypellus near base. Antennal bases near middle or posteroventral (lower) corners of eyes. Antennae long, 1.5x width of head or longer. Genae incised laterally. Fine erect seta on gena close to lateral frontal suture. Maxillary sensillum closely adjacent to lorum. Lorum closely adjacent to lower genal margin. Antennal ledges absent. Mesial margin of eye notched. Eye .5x width of crown or wider. Ocelli medium sized to large, close to eyes, less than 1/3 distant from eye to crown apex, on anterior margin, partially visible in dorsal view.

Thorax. Pronotum lateral margin carinate, lateral margin less than 1/2 basal width of eye or lateral margin longer than 1/2 basal width of eye, with tranverse striations.

Wings. Forewing rounded apically, macropterous, transparent, appendix restricted to anal margin, with 3 anteapical cells, outer anteapical cell rounded or truncate apically, not particularly small, 1st and 2nd apical cells normal, vein R1 diverging distad of R fork, without extra costal veins, with a few extra crossveins on corium, without extra crossveins in brachial cell, without false veins, with one crossvein between A1 and claval suture, anal veins not strongly curved, meeting commisural margin obliquely, claval cells without definitely delimited transparent or pale opaque spots, A1-A2 crossvein absent, inner anteapical cell open. Hind wing veins R4+5 and M1+2 separated by a crossvein or touching for a very short distance, M3+4 and CuA separated by a crossvein.

Legs. Profemur with AM1 seta only, AM1 seta near ventral margin of femur. Profemur number of intercalary row setae: 7-14 . Profemur row AV with short, stout macrosetae. Profemur number of row AV setae 18-30 . Profemur AV1 seta poorly differentiated from intercalary row setae. Protibia row AD with one macroseta. Protibia row PD number of macrosetae: 4 . Mesotrochanter with one stout apical seta. Metafemur apex penultimate set of macrosetae with 2 setae, antepenultimate set of macrosetae with 1 seta, without extra macrosetae proximal of typical 2+2+1. Metatibia proximal seta of PD distad of proximal seta of AD or equidistant from tibia base, row AD intercalary setae simple, without basal stout setae on dorsal surface, row PD macrosetae much longer than AD macrosetae, row PD macrosetae alternating short and long, basal dorsal width subequal to width near apex, pecten with median seta much longer than adjacent setae. Metatarsomere I not expanded apically, long, slender, plantar setae all simple. Metatarsomere I pecten: number of platellae 3 . Metatarsomere I pecten inner apical seta tapered.

Male Genitalia. Valve articulated with pygofer and subgenital plates, with short point of articulation with pygofer. Pygofer dorsoapical margin incised to near mid-length, macrosetae well differentiated into several rows, without dense tufts of thick or fine setae, without ventral tooth, spine, or process, without dorsal tooth, spine, or process or with dorsal tooth, spine, or process, posterior margin without teeth or serrations. Segment X sclerotized laterally and dorsally, not particularly long or broad. Subgenital plates triangular, longer than width, outer margin concave at least in part, or straight, apex long, filamentous and often with long fine setae, without macrosetae, with numerous densely situated long fine setae laterally and/or dorsally. Style preapical lobe short, rounded or pointed, apophysis shorter than rest of style, apophysis smoothly curved, apophysis apex pointed, apophysis inner (posterior) margin without teeth, apophysis smooth or apophysis irregularly denticulate. Aedeagus with a pair of processes arising from base, fused to aedeagus, without medial processes, apex simple, depressed, flagellum arising from ventral part of socle, symmetrical, moderate to long, gonoduct not sclerotized basad of aedeagal base, gonopore apical or gonopore subapical, on ventral side, with a single shaft and gonopore, preatrium absent or very short. Phragma membranous. Connective anterior arms somewhat divergent, (Y- or U-shaped), stem present, shorter than anterior arms, articulated with aedeagus, without processes.
