Phlyctinus xerophilus

Body integument dark red, head and prothorax usually black. Sides slightly convex, widest before middle of length (w/l ratio 0.73–0.77). Integument smooth, shiny, finely punctate; interstriae raised, 2–4× as wide as striae in basal half. Rostrum longer than wide (w/l ratio 0.80) in both sexes, base as wide as apex, sides slightly concave near middle. Nasal plate V-shaped, reaching level of antennal insertion basally, bare of scales, with short setae in scattered punctures and 3 pairs of long setae apically near mandible insertion. Epifrons as wide at base as eye width, narrower than distance between eyes, sides widening from base to apex, with a longitudinal carina from basal transverse groove to nasal plate. Antennal scrobes slightly curved, directed to middle of eye, separated from it by a strip of scales as wide as eye diameter. Forehead with short longitudinal furrow between eyes; scales and setae arranged centripetally. Funicle segments 1–2 elongate, segment 1 shorter (0.70×) than 2; segments 3–7 longer than wide, conical, 3–5 shortening apicad, 5–6 widening apicad. Pronotum slightly wider than long (w/l ratio 1.20), widest slightly before middle, apical margin 0.75× as wide as base, sides rounded, apical half slightly concave; integument with dense cover of elongate granules oriented parallel to median carina; median carina raised, smooth, shiny, not reaching apical and basal margins. Each elytral interstria with a series of semi-erect, elongate whitish scales, condensed on callosities. Ventrite 1 shorter than 2+3+4, slightly convex in middle (female) or concave with erect setae slightly shorter than claws (male); ventrite 5 longer than 3+4, with erect setae in middle and near apex and a smooth longitudinal carina (female) or with large cavity extending on apical 2/3, with long erect setae condensed on margins and along a longitudinal line at bottom of cavity (male).
