Diagnosis
This species is most easily confused with Cratocerus tanyae and can generally be separated by its slightly larger overall body size and the differently shaped pronotum (Fig. 9e, f). The size and shape of the median lobe of the male genitalia distinctly diagnose these two species (Fig. 11d, e).
Description
Size average for the genus, ABL 4.8–5.5 mm, TW 1.8–2.4 mm. Color. Head and prothorax brunneopiceous; elytra and abdominal sternites brunneous; legs, antennae, and mouthparts rufotestaceous. Head. HL 0.7–0.9 mm, HW 0.7–0.8 mm. One supraorbital seta present over each eye. Apices of mandibles slightly curved, at less than 45 degree angle to mandibular midline. Apical maxillary palpomere length 6 × width at base. Mentum with triangular lateral lobes. Thorax. Pronotum (Fig. 9f) with distinct median impression, one distinct basal fovea laterad; one lateral seta located on apicolateral pronotal bead; one posterior seta present on posterior bead and projecting over posterior angle; pronotal anterior margin convex, greatest width anterad of center; pronotal width 1.2–1.3 × pronotal length. Elytral length 1.5–1.7 × combined elytral width. Legs. Protibia with three distinct, stout spines confined to distal half of lateral margin; distance between spines 1 and 2 equidistant to distance between spines 2 and 3; one additional smaller spine laterad to spine 1 and one additional smaller spine anterad to spine 1, both only slightly visible with magnification of 125×, clearly visualized with scanning electron microscopy (Fig. 10d). Genitalia, male. Median lobe curved sharply, between forty-five and ninety degrees with respect to basal 1/3, remaining 2/3 with continuing curvature; very slight apical expansion; length average for the genus. Left paramere simply curved (Figure 11e). Genitalia, female. Spermatheca extremely thin, filamentous, form similar to spermatheca of Cratocerus kavanaughi (Fig. 12c), but much longer (2× length) and relatively narrower (1/2× width).
Etymology
The specific epithet refers to a series of specimens bearing locality labels specifying “Indupalma”. This series represent the specimens that were first recognized as constituting part of this quite variable new species of Cratocerus. Indupalma is treated as an adjective.
Distribution
This widespread species (Fig. 13) has been collected in Belize, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, French Guiana, Guatemala, Mexico, Panama, and Peru.
Ecology
This species has been collected under the bark of rotting, fallen trees.
