NOV. ( FIGS 6A, B , 8G , 9A–F , 20B ) Zoobank registration: urn: lsid: zoobank. org:act: A0499A2C-83A5-4C42-8422-B22FF60AB8F4 Type material: Holotype , female, BRAZIL : São Paulo , Bras. Mráz Lgt, Mus. Pragense ( NMPC ). Paratypes : Same data as holotype ( two females : 1, NMPC ; 1, MIZ ); Rio de Janeiro , Alte Bondlin, ex coll. Kessel, Mus. Zool. Polonicum Warszawa 19/46 ( one female , MIZ ); Bocaina, ex coll. Kessel, Mus. Zool. Polonicum Warszawa 19/46 ( one female , MIZ ). Diagnosis: Karumbe brethesi can be easily distinguished from K.pakaluki and K.geiseri by having larger body ( Fig. 6A, B ), peculiar punctations on dorsal surface of the body ( Fig. 9E ) (vs. setiferous punctures and additional round depressions in K.geiseri and K.pakaluki ), the central area of the metaventrite covered with setiferous punctures inserted in wide foveate impressions ( Fig. 9F ) (simple setiferous punctures in K. pakaluki and K. geiseri ), the pronotal disc with elongate, narrow concave area along the internal lateral carina ( Fig. 9C ), prosternal process with carinae convergent anteriorly ( Fig. 9D ) (subparallel in K. pakaluki and K. geiseri ), and the terminal labial palpomere elongate and acuminate, 2.2 times as long as wide ( Fig. 9B ) (in K. pakaluki and K. geiseri : short and apically rounded, 1.2–1.4 times as long as wide). Description: Body: length 1.40–1.45 mm , 1.3 times as long as wide, 2.0 times as long as high, short oval and moderately convex, dark brown with infuscateyellowish legs, antennae and palpi ( Fig. 6A, B ). Antenna nearly 0.35 of length of body; antennomeres 1–7 longer than wide; antennomeres 8–9 subquadrate. Apical labial palpomere elongate and acuminate, 2.2 times as long as wide at its base ( Fig. 9B ). Pronotum 2.0 times as wide as long, 1.9 times wider at widest part than on front angles ( Fig. 9C ). Area between lateral edge and internal lateral carina concave, wide and continuously weakly narrowing posteriorly. Anterior crenulate margin moderately wide. Pronotal disc deeply concave along internal lateral carina. Basal margin bordered with weakly crenulate bordering line. Prosternal process, narrowest near half-length, weakly widened apically with apex about 0.7 of the width of procoxal cavity ( Fig. 9D ); with lateral carinae convergent anteriorly (comparatively narrowly separated throughout most of their length) almost reaching anterior quarter length of prosternum, central part depressed. Elytra 1.00– 1.35 mm long, about as long a wide, 2.6– 2.7 times as long and 1.4 times as wide as pronotum; lateral margins visible from above. Elytral dorsal surface with most punctures with peculiar raised sculpture consisting of a small ring and an accessory point posteriorly ( Fig. 9E ). Mesoventral process about 1.1 times as wide as mesocoxal diameter. Metaventrite with setiferous punctures at central area placed in large and shallow foveate impressions ( Fig. 9F ). Hindwings present, well developed ( Fig. 7H ). Legs. Pro-trochanters rounded; meso- and metatrochanters flattened and angulately produced posteriorly ( Fig. 9F ). Abdomen with ventrite 1 with comparatively shallow, rounded postcoxal lines ( Fig. 9F ). Ventrite 5 with posterior margin straight. Female genitalia ( Fig. 8G ). Bursa copulatrix large, with apical outlet of sperm duct. Spermatheca submembranous, moderately large, elongatesubcylindrical, oblong; sperm duct short; accessory gland small, membranous, of irregular shape. Male unknown. Etymology: This species is dedicated to Jean Brèthes, French/Argentinian entomologist who established the family Cerasommatidiidae in 1925. Distribution: Brazil ( Fig. 20B ).
