Paralectotype (FMNH), female.
Diagnosis. Ctenopeuca heynei differs from C. romani by having head and pronotum with the same color and abdominal segments III–IV slightly lighter than V–VII (Figs. 1–3); antennomere 4 quadrate; posterior margin of abdominal tergum VIII of male with a prominent tooth on each side of serrate region (Fig. 21); posterior margin of abdominal tergum VIII of female with a slightly tooth on each side of emarginate region (Fig. 26).
Redescription. Male. Body length 6.0 mm, humeral width 1.0 mm. Head, antennomeres 4–11, pronotum, postero-lateral angle region of elytra and abdominal segments IV–VII brown to dark brown, the rest of body yellowish to light brown (Fig. 2). Antennomere 4 quadrate. Abdominal spine of tergum IV somewhat quadrate in lateral view (Fig. 1, ST4); spine of sternum III three times longer than the spine of sternum IV (Fig. 1, SS3 and SS4); tergum VIII with posterior margin serrate on mesal three-fifth, a prominent tooth on each side of serrate region (Fig. 21); sternum VIII with posterior margin strongly projected medially (Fig. 22); median lobe of aedeagus strongly curved paramerally in lateral view (Fig. 24), apical half with ventral face evenly curved. Female. Similar to male, except tergum VIII with posterior margin emarginate on mesal three-fifth, a prominent tooth on each side of emarginate region (Fig. 26); sternum VIII with posterior margin slightly projected medially (Fig. 27); spermatheca not found.
Distribution. Peru: Junín (Chanchamayo) (Fig. 34)
Biological notes. Only the type material is known and collected from Chanchamayo, presumably in the province in northern Junín region, Peru. The lectotype has a label indicating that the specimen was collected at an altitude of 1000 meters.
