Description

Body. Body length 4-8 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 stramineous or yellow or brown. Bright orange or red coloration absent. Crown with a single black or fuscous band or with colored maculae, spots, or lines.

Head. Head subequal to or wider 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 broad, median length shorter than or nearly equal to width between antennal pits, not widening abruptly dorsad of antennal pits, texture shagreen. Clypellus parallel sided or tapering apically, relatively flat or tumid. Lorum subequal to or wider than clypellus near base or distinctly narrower than clypellus near base. Antennal bases near middle or posteroventral (lower) corners of eyes. Antennae short, less than 1.5x width of head. Genae incised laterally. Fine erect seta on gena distant from lateral frontal suture. Maxillary sensillum closely adjacent to lorum or well separated from lorum. Lorum closely adjacent to lower genal margin. Antennal ledges weakly developed (carinate or weakly carinate). Mesial margin of eye entire. Eye less than .5x width of crown. Ocelli medium sized to large, close to eyes, less than 1/3 distant from eye to crown apex, dorsad of anterior margin, completely visible in dorsal view.

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

Wings. Forewing rounded apically, macropterous or submacropterous, transparent, appendix absent or reduced, with 3 anteapical cells, 1st and 2nd apical cells normal, vein R1 diverging distad of R fork, without extra costal veins, without 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, AM 1 seta near mid-height of femur. Profemur number of intercalary row setae: 6-15 . Profemur row AV with short, stout macrosetae or row AV with relatively long macrosetae. Profemur number of row AV setae 10-20 . Profemur AV1 seta poorly differentiated from intercalary row setae. Protibia row AD with 5 or more macrosetae. Protibia row PD number of macrosetae: 5-6 . 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 or row AD intercalary setae cucullate, without basal stout setae on dorsal surface, row PD macrosetae subequal in length to AD macrosetae, row PD macrosetae alternating short and long or row PD macrosetae more or less equal in length, basal dorsal width much wider than width near apex, pecten with setae subequal in length. Metatarsomere I expanded apically, short, stout, plantar setae all simple. Metatarsomere I pecten: number of platellae 6-7 . Metatarsomere I pecten inner apical seta platelliform.

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 or with ventral tooth, spine, or process, without 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 convex, apex pointed, macrosetae scattered, irregularly arranged or with two lateral rows of macrosetae, or with some irregularly arranged macrosetae near lateral margin, without or with few long fine setae or with some medium to long fine setae laterally or dorsally. Style preapical lobe short, rounded or pointed or preapical lobe prominent; lobate, digitate, or pointed, apophysis shorter than rest of style, apophysis straight, apophysis apex rounded, apophysis inner (posterior) margin without teeth, apophysis irregularly denticulate. Aedeagus without processes arising from base, without medial processes, with one pair of apical processes, depressed, flagellum arising from ventral part of socle, symmetrical or asymmetrical, moderate to long, gonoduct not sclerotized basad of aedeagal base, 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, without processes.

Female Genitalia. Pygofer with numerous macrosetae. Ovipositor not protruding far beyond pygofer apex. First valvula convex, dorsal sculpturing pattern concatenate or dorsal sculpturing pattern imbricate, with overlapping scales or dorsal sculpturing pattern granulose, sculpturing marginal. First valvula dorsal sculpturing not distinctly more elongate than apical sculpturing. First valvula without or with indistinctly delimited ventroapical sculpturing. First valvifers not fused anteriorly. Second valvula broad, tapering apically, without dorsal median tooth or with dorsal median tooth, teeth on apical 1/3 or more, teeth small and short, longer than tall, regularly to irregularly shaped, teeth not serrated or teeth serrated. Third valvula without distinct setae.
