Bothriocera

Body length with wings 4.8–5.25 mm, without wings 2.7–3.32 mm. Head in dorsal view narrower than pronotum, broad and subrectangular, strongly produced beyond anterior margin of eyes; anterior margin concave, as broad or broader than interocular width at base; lateral and posterior margins of vertex carinate; subapical transverse carina between anterior margins of eyes medially joining median carina extending anteriorly onto frons; median carina of vertex absent posterior to subapical transverse carina; posterior margin of vertex nearly transverse between eyes. In frontal view, sides of frons and clypeus carinate; dorsolateral portions of frons expanded and auriculate at level of antennae; longitudinal midline of frons carinate only on upper half; frontal ocellus prominent; ventral margin of frons may bear a variably expressed broadly U-shaped ridge above frontoclypeal suture. In lateral view, head declinate to level of antennae; antennae arising from a deep elongated depression in front of eye formed by lateral carinae of frons defining a foliate, inverted C-shaped concavity; ocellus prominent above antennae in front of anterodorsal margin of eye. Pronotum extremely narrowed medially, may be entirely concealed medially by hind margin of head. Forewings broadly spatulate, held broadly tectiform, only slightly or not overlapping on inner margin, usually boldly patterned; veins without prominent setae-bearing pustules. Phallus bearing varied but few processes or projections from shaft; endosoma elongate, sinistrally curving into a partial helix, bearing varied processes.
