Anderson, Robert S., 2010, A taxonomic monograph of the Middle American leaf-litter inhabiting weevil genus Theognete Champion (Coleoptera: Curculionidae; Molytinae; Lymantini) 2458, Zootaxa 2458 (1), pp. 1-127 : 51-52

43. Theognete confusa Anderson , new species ( Figures 155 , 190 , 225 )

Diagnosis. Size. Length, male, 3.65–3.88mm; female, 3.77–4.02mm. Width, male, 2.08–2.25mm; female, 2.30mm. Pronotum subcordate, regularly rather deeply and densely punctate, punctures large, no impunctate areas evident; scales feebly arched, moderately large and broad, not clumped, distinctly plumose; flanks with punctures subcontiguous but no sulci present. Elytra with scales as on pronotum, arranged in a single row on each interval; scales long, apices overlapping; strial regions lacking scales; posteroloateral area of elytra with a series of 3–4 distinct punctures. Male tergite VIII emarginate in middle. Aedeagus as in Fig. 190 .

Geographical distribution. México (Chiapas).

Natural history. Collected from berlese extraction of cloud forest leaf litter at an elevation of 2000m.

Derivation of specific name. Named from the Latin confusus, meaning confused, because of structural similarity to (and confusion with) the sympatric T. balli and T. galvezi .
