Elytrimitatrix (Grossifemora) curoei Santos-Silva and Le Tirant , new species ( Figs. 13–16 )

Description. Holotype Male. Head dark brown, except for palpomeres brown with distal area yellowish brown, clypeus brown on basal half, yellowish brown on remaining surface, and labrum yellowish brown. Scape and antennomeres III–X reddish brown, with apex brown (this area gradually lighter toward distal antennomeres). Prothorax dark brown with anterior and basal areas dark reddish brown. Mesothorax dark brown, with parts of mesepisterna slightly reddish brown. Metathorax dark brown, with wide lateral band dark reddish brown. Elytra orange-brown, maculated with dark brown areas ( Fig. 13 ), including punctures. Ventrites dark brown, except for yellowish apex of ventrites I–IV. Femoral peduncle yellow; femoral club dark brown. Tibiae black on base, yellow on central region, dark brown on apex. Tarsi reddish brown. Setae and pubescence yellowish. Head: Frons narrow, very finely, moderately sparsely punctate; with short, moderately abundant setae, distinctly sparser medially. Area between antennal tubercles and upper eye lobes mostly smooth, except for very finely punctate central area between eyes; with short, moderately abundant setae, except for narrow glabrous area close to eyes, small region, medially, between antennal tubercles, and longitudinal central area between eyes; with some long setae near eyes. Vertex finely, moderately sparsely punctate, except for smooth, longitudinal, central area; with short, moderately abundant setae laterally, glabrous centrally, longitudinal region, subglabrous on transverse area close to prothorax. Area behind eyes smooth on area close to eyes, finely, moderately sparsely punctate on area close to prothorax (punctures gradually finer, sparser toward inferior side of lower eye lobe); with short, abundant setae on area close to upper eye lobes, gradually sparser toward inferior side of lower eye lobes. Submentum with short, sparse setae interspersed with some long setae. Maxillary palpomere IV securiform, with apex obliquely truncate. Distance between upper eye lobes 0.20 times length of scape; distance between lower eye lobes in ventral view 0.55 times length of scape; largest width of upper eye lobes 0.90 times largest width of scape. Antennae (left antenna missing antennomeres IX–XI) 1.8 times elytral length; reaching elytral apex at distal third of antennomere VIII. Scape without depression on base of dorsal surface; moderately finely, abundantly punctate on basal half, gradually sparser toward apex; with short, sparse setae throughout, interspersed with some long setae near apex. Antennal formula based on antennomere III: scape = 0.89; pedicel = 0.17; IV = 1.04; V = 1.00; VI = 0.96; VII = 0.91; VIII = 0.87; IX = 0.76; X = 0.74; XI = 0.80. Thorax: Prothorax, including lateral tubercles, transverse, 1.25 times as wide as long; lateral tubercles large, not spiniform at apex. Pronotum with 5 tubercles: 2 large, distinctly elevated, subrounded, placed on each side of anterior half; 2 smaller, subrounded, placed on each side of basal half; 1 elongate, placed medially. Pronotal surface shiny, very finely punctate, except on longitudinal tubercle and inner side of rounded tubercles; with short, moderately abundant setae, except for glabrous area on part of latero-anterior tubercles and on longitudinal tubercle. Basal half of prosternum with short, moderately abundant setae laterally and close to procoxal cavities, glabrous on remaining surface; anterior half with short and long, sparse setae. Metasternum with short, abundant setae laterally, gradually sparser toward center, mainly on large, triangular region from about anterior quarter to metacoxal cavities. Metepisterna with short, abundant, decumbent setae. Elytra with 6 rows of punctures: 1 close to suture, almost reaching apex (punctures sparser toward apex); 1 close to previous row, reaching middle of elytra; 1 at middle between scutellum and humerus, almost reaching apex (punctures sparser toward apex); 1 anteriorly close to humerus, almost reaching apex; 1 laterally from base to about distal quarter (punctures notably sparser toward apex); 1 close to lateral margin (punctures notably finer than in other rows), slightly distinct after distal third. Elytral surface pubescent (pubescence distinctly not obscuring integument); apex uniformly narrowed, not spiniform. Abdomen: Ventrites I–IV with short, moderately abundant setae, except for glabrous area on center of I, and base and apex of II–IV; ventrite V with short, moderately abundant setae throughout, interspersed with long setae; apex of ventrite V subtruncate. Legs: Profemur somewhat fusiform; with spiniform tubercles on ventral side of club; with short, sparse setae, interspersed with long setae ventrally. Mesofemur slightly clavate, with tubercles shorter than on profemur. Metafemur subcylindrical.

Female. Similar to male, but differs as follows: antennae as long as 1.6 times elytral length, reaching apex at base of antennomere IX; maxillary palpomere IV fusiform.

Dimensions. Holotype male/ paratype males/ paratype females. Total length (including mandibles) 14.10/11.90–15.60/ 14.70–16.30 mm; prothoracic length 1.80/1.70–2.10/2.00 mm; anterior prothoracic width 1.60/1.45–1.80/ 1.75–1.90 mm; basal prothoracic width 1.80/1.45–2.00/1.90–2.00 mm; broadest prothoracic width 2.40/2.05–2.70/ 2.65–2.70 mm; humeral width 2.90/2.40–3.25/ 3.10–3.60 mm; elytral length, 10.30/8.60–11.20/ 10.50–12.10 mm.

Type Material. Holotype male from MEXICO: Oaxaca: Santiago Xiacui, El Quelite , 17°17′33N / 96°23′W, 2,350 m, 21.VI.2006, D. Curoe and A. Ramirez col. ( MZSP) . Paratypes from MEXICO: Oaxaca: same data as holotype (1 female, ICMQ) ; Sierra de Juárez , 1,980 m, 15.V.1996, G. Nogueira col. (2 males, DHPC) ; same locality data except 1,650 m (1 male, DHPC) ; same locality data except 10-11.V.1997, G. Nogueira col. (1 female, MZSP) ; same locality data except 850 m, 15.V.1998, G. Nogueira col. (1 male, TAMU) ; San Pedro Teutila , 1,650 m, 26.VI.1998, G. Nogueira col. (1 male, CNIN) .

Additional Material. MEXICO, Oaxaca: Sierra de Juárez , 1,020 m, 17.V.1996, G. Nogueira col. (1 male, DHPC). This specimen was not included as a paratype because the head and prothorax are of a male, but they are glued to the body (remaining thorax and abdomen) of a female .

Etymology. This species is named after our friend Daniel Curoe.

Remarks. Elytrimitatrix curoei is similar to E. lineatopora , but differs as follows: upper eye lobes almost as wide as broadest width of scape, not distinctly narrowed toward apex; femoral club totally dark brown. In E. lineatopora , the upper eye lobes are distinctly narrower than the broadest width of the scape and distinctly narrowed toward apex, and the femora are dark over the central third, with the basal and distal thirds distinctly orange.

In the key to species of the subgenus in Santos- Silva and Hovore (2008), E. lineatopora was misidentified. Thus, the inclusion of the new species, similar to E. lineatopora , can lead to mistakes in identification.
