(Figures 8–9)  
 Holotype male. Integument brown; parts of mandibles and genae, and elytral apex darker.   
Head dorsally covered with dense, alveolate punctures; pubescence very short, almost inconspicuous, with long seta laterally near clypeus. Clypeus punctate-alveolate. Labrum transverse, centrally deeply longitudinally sulcate. Mandibles laterally with long, sparse setae. Genal apex slightly projected forward, moderately acute. Antennal tubercles distant. Submentum punctate-alveolate; with short, moderately abundant, decumbent setae, mixed by long, erect, sparse setae. Distance between superior ocular lobes equal to 0.4 times length of scape; distance between inferior ocular lobes equal to 0.5 times length of scape. Antennae as long as 1.9 times elytra, reaching elytral apex near apex of antennomere VIII. Antennal formula based on antennomere III: scape = 0.74; pedicel = 0.22; IV = 1.05; V = 1.07; VI = 1.07; VII = 1.16; VIII = 1.14; IX = 1.11; X = 1.07; XI = 1.31.  
Pronotum punctate-alveolate, except impunctate, longitudinal central band, from near basal constriction to anterior third; pubescence very short, slightly conspicuous on disk, laterally more distinct. Prosternum with transverse, wide area densely punctate-alveolate and pubescent at basal half; distal half sparsely punctate, with short, sparse setae. Metasternum laterally coarsely, abundantly punctate, distinctly sparser, finer toward center; pubescence moderately abundant, except around metasternal sulcus. Elytra moderately finely, densely punctate throughout; covered with short, moderately abundant, decumbent setae; distal fifth with moderately long, erect, sparse setae (mainly around suture); apex slightly projected at suture. Ventrites abundantly punctate (mainly laterally on I-IV) and pubescent. Metatarsomere I about as long as II-III together.  
 Female. Antenae as long as 1.65 times elytra, reaching elytral apex near apex of antennomere X; antennal formula based on antennomere III: scape = 0.77; pedicel = 0.23; IV = 0.95; V = 1.02; VI = 1.02; VII = 1.02 VIII = 0.93; IX = 0.98; X = 0.84; XI = 1.02.   
 Variability (male and female). Integument light-brown; legs light-brown.   
 Dimensions in mm. Holotype male - total length (including mandibles), 13.0; prothoracic length, 2.2; largest prothoracic width, 2.0; humeral width, 2.5; elytral length, 8.9. Paratypes (male/female) - total length (including mandibles), 8.3–11.9/9.3–12.1; prothoracic length, 1.4–2.0/1.6–2.0; largest prothoracic width, 1.3–1.9/1.5–1.9; humeral width, 1.6–2.3/1.9–2.3; elytral length, 5.6–8.0/6.3–8.1.   
 Type material. Holotype male, PARAGUAY, Boquerón: Parque Nacional Teniente Agripino Enciso (Chaco), 4.XI.2001, C. Aguilar Julio col. (MZSP). Paratypes, 4 males, 2 females, same data as holotype (VMDC). Caaguazú: Repatriación, female, 27.XI.2010, Sv. Bilý col. (OMCO).   
 Etymology. Lembu dieguezi is named for Víctor Manuel Diéguez, for his collaboration by sending specimens for study.
