(Fig. 4–6)
Type material: Holotype female. MEXICO, Hidalgo: 1 km N Tlanchinol (Hwy 105), V.30 -31.1984, G. Nogueira col. (CNIN).
Dimensions in mm. Total length, 16.1; pronotal length (centrally), 2.5; anterior pronotal width, 2.1; posterior pronotal width, 2.2; humeral width, 3.5; elytral length, 10.7.
Description. Holotype female. Integument dark brown; postclypeus laterally, anteclypeus, labrum, most mouthparts, scape, trochanters, femora, tibiae (slightly brownish on base), tarsomeres I, narrow distal band on ventrites I–IV (mainly III–IV) orangish; mandibles mostly reddish-brown on basal 2/3, black on distal third; antennomeres III–X orangish-brown on basal half, brown on distal half (left antenna missing antennomeres VII– XI; right antenna missing antennomere XI); elytra with longitudinal, irregular, reddish-brown areas, from about basal 1/5 to about middle; tarsomeres II orangish on base, gradually brown toward apex; tarsomeres III brown; tarsomeres IV–V reddish-brown (apex of claws dark brown).
Head. Frons finely and moderately abundantly punctate laterally, smooth centrally; with short setae laterally, gradually sparser toward glabrous center. Area between antennal tubercles smooth, except for fine punctures close to longitudinal sulcus; with short, sparse setae close to longitudinal sulcus, anteriorly interspersed with some long setae. Area between upper eye lobes coarsely, sparsely punctate, interspersed with fine punctures (punctures more abundant close to longitudinal sulcus); with short, sparse setae, except for long setae close to antennal tubercles. Vertex finely, sparsely punctate, except for smooth area close to longitudinal sulcus; with short, sparse setae, interspersed with long setae close to eyes. Area behind upper eye lobes finely, sparsely punctate; with short setae close to eye, glabrous on remaining surface. Area behind lower eye lobes smooth, tumid close to eye; with long, sparse setae close to eye, glabrous on remaining surface. Area between lower eye lobes and gulamentum with long, erect, sparse setae. Gulamentum shiny, smooth on basal half; tumid, finely, sparsely punctate, with short, sparse setae between lower eye lobes; depressed, punctate-vermiculate, with short, sparse setae on anterior region. Genae finely punctate, with short, sparse setae, except for smooth, glabrous area close to apex. Antennal tubercles mostly smooth, glabrous, except for sparse, short setae anteriorly. Longitudinal sulcus distinct from clypeus to prothoracic margin. Postclypeus moderately coarsely and abundantly punctate; with short, sparse setae interspersed with long setae (mainly laterally). Distal segment of maxillary palpi fusiform. Distance between upper eye lobes 0.25 times length of scape; distance between lower eye lobes in ventral view 0.65 times length of scape. Antenna (right – from base to apex of antennomere X) 1.75 times elytral length; reaching elytral apex at distal quarter of antennomere VIII; antennal formula based on antennomere III: scape = 0.92; pedicel = 0.13; IV = 0.96; V = 0.92; VI = 0.89; VII = 0.89; VIII = 0.85; IX = 0.76; X = 0.59.
Thorax. Prothorax, including lateral tubercles, 1.25 times wider than long; lateral tubercles placed about middle, large, conical, with apex spiniform, upturned. Pronotum with five distinct gibbosities: two on each side, subrounded; one elongated, centrally. Pronotal surface finely, abundantly punctate between gibbosities, slightly sparser on transverse basal region and on outer side of subrounded gibbosities, very sparse on dorsal and inner side of subrounded gibbosities, smooth on central gibbosity, sparse on anterior region (punctures distinctly finer than those between gibbosities); with short, decumbent, sparse setae between gibbosities, interspersed with long setae, except for glabrous dorsal side of subrounded gibbosities and central gibbosity. Prosternum smooth basally, slightly transversely striate centrally, finely and sparsely punctate anteriorly; basal 2/3 with short, moderately sparse setae laterally, slightly denser around procoxal cavities, glabrous on remaining surface; anterior third with long, sparse, erect setae. Prosternal process with short, abundant setae. Mesosternum, mesepimera and mesepisterna with short, decumbent, abundant setae (not obscuring integument). Metepisterna with short, decumbent, abundant setae. Metasternum very finely, abundantly punctate laterally, gradually sparser toward center; with short, abundant setae laterally (interspersed with long setae), gradually sparser toward glabrous center. Scutellum minutely punctate, with short, decumbent setae. Elytra. Surface minutely, abundantly punctate; basal half with coarse, deep punctures aligned in five rows, of which the second is the shortest; with short, abundant, decumbent setae (not obscuring integument) interspersed with long setae at basal and distal quarter, and laterally close to margin; carina well-marked from base to about distal third; apex bispinose (spine of outer angle finer and longer than that on sutural angle). Legs. Profemora fusiform; meso- and metafemora slightly claviform (missing left middle leg); metatarsomere I about as long as II–III together; right mesotarsus and left metatarsus missing tarsomere V.
Abdomen. Ventrites I–IV minutely, abundantly punctate laterally, gradually sparser toward center, smooth on narrow distal band; with short, abundant setae laterally (interspersed with long setae), gradually sparser toward center, glabrous on narrow distal band. Ventrite V minutely punctate, with short setae interspersed with long setae throughout.
Etymology: The new species is named after Guillermo Nogueira, collector of the holotype, who also made innumerable contributions to the knowledge of Mexican Coleoptera, especially Scarabaeidae.
Remarks. Elytrimitatrix (Grossifemora) nogueirai is similar to E. (G.) bispinosa Santos-Silva & Hovore, 2008, but differs as follows: pronotal punctation moderately fine, not very distinct; spine of external elytral apex longer, and longer than sutural one. In E. (G.) bispinosa the pronotal punctation is coarser, very distinct and confluent, and the spine of external elytral apex is shorter and about as long as sutural one. In the holotype of E. (G.) nogueirai the setae of the dorsal surface of the body are distinctly less conspicuous than in E. (G.) bispinosa. However, the setae of the holotype of the new species could be lost, because the specimen is not in very good condition.
At the time of the collection of the holotype, the type locality was a forest dominated by Liquidambar sp. and Quercus sp. which no longer exists (G. Nogueira, pers. comm.).
