Coccoderus costae sp. nov.

( Fig. 6A–D )

Diagnosis. External apex of antennomeres III–V with short spiniform projection ( Fig. 6D ); antennomere III about 3x length of IV ( Fig. 6A, D ). Elytra yellowish and translucid, with 3 elliptical eburneous callosities, anterior one shorter; distance between basal and medial callosities equal to length of basal callosity; medial and apical callosities near to each other ( Fig. 6A ).

Description. Holotype female. Integument mostly orange; inner area of mandible, pronotal tubercles, lateral tubercles of prothorax, and apex of ventrites black; apex of antennomeres light brown; elytra yellowish and transparent; tarsomeres I–III brown and tarsomere V yellowish; tarsal claws dark brown. Elytron with three elliptical eburneous callosities, with different lengths, one basally, one medial, and another on posterior half, with brown area on anterior and posterior margin of the medial and posterior callosities; distance between anterior and medial callosities equal to length of anterior callosity; distance between medial and posterior callosities about one-third length of medial callosity ( Fig. 6A ). Clypeus, labrum, mandibles, labial and maxillary palpi, antennae, and legs with sparse, long, and erect yellowish setae. Prothorax subglabrous, with rows of dense and erect setae on anterior and posterior margin. Ventral region covered with dense, long, and decumbent yellowish pubescence, except on head and prosternum.

Head and antennal tubercles with thick, shallow, dense punctation. Antennal tubercles well separated; with shallow sulcus between antennal tubercles. Upper eye lobes well separated, distance between them more than 3x width of one upper lobe; upper eye lobe with eight rows of ommatidia dorsally, five toward lower eye lobe. Mandible with one tooth on inner margin. Antennae not reaching elytral apex; external apex of antennomeres III–V with short spiniform projection; antennomere III about 3x the length of IV; antennomeres IV–XII with subequal length.

Prothorax wider than long; with thick, shallow, and dense punctation; each side of prothorax with two rounded tubercles ( Fig. 6D ). Pronotum with two elevated tubercles, rounded apically. Prosternal process without tubercle; rounded apically. Elytral apex with lateral and sutural spine. Femora subfusiform; apex of meso- and metafemora with spine on inner margin. Tibia as long as femora; cylindrical, expanding toward apex. Ventrite 5 with apical margin emarginate.

Measurements, in mm. Total length: 28.4; prothorax length: 4.9; anterior width of prothorax: 4.5; posterior width of prothorax: 4.8; elytral length: 20.6; humeral width: 6.2.

Etymology. The specific name is in honor of the mother of the first author, Gilvanete Costa, in grateful for all the support and education.

Type material. Holotype female, BRAZIL: “ BAHIA: Aracatu, Fazenda Lagoa do Tamburi , BA262, km 400, sentido Vitória da Conquista /Brumado, Caatinga arbórea, trilha do umbuzeiro, 1.x.2013, Ferreira, A.S. leg.” ( MZFS) ( Fig. 6E ).

Remarks. Coccoderus costae sp. nov. is morphologically similar to the females of C. sicki Lane, 1949 for the presence of short spiniform projection on the external apex of the antennomeres III–V, and females of C. sexmaculatus Buquet, 1840 ( Fig. 6F ) for the length of the eburneous callosities on the elytra, length and position of the pronotal tubercles, and antennomeres IV–XII subequal in length. However, C. costae sp. nov. has the antennomere III about 3x longer than IV; antennomeres IV–XII subequal in length ( Fig. 6A–D ); pronotal tubercles distant from each other, about 3x the width of the scape, and eburneous callosities on the elytra with different lengths ( Fig. 6D ). In females of C. sicki , the antennomere III is 0.33x longer than IV; antennomeres IV–XII with decrescent length; pronotal tubercles larger and about twice the width of the scape, and eburneous callosities on the elytra with subequal length. Coccoderus costae sp. nov. differs from C. sexmaculatus by antennomere III about 3x longer than IV ( Fig. 6F ); the elytra yellowish and translucid; distance between the anterior and medial callosities is the same length of the anterior callosity; medial and posterior callosities on the elytra about one-third of the length of the medial callosity ( Fig. 6F ). In females of C. sexmaculatus , the antennomere III is slightly longer than twice the length of IV; elytra orangish brown and opaque, and distance between the anterior and medial eburneous callosities on the elytra about two-thirds of the length of the anterior callosity; medial and posterior callosities about two-thirds of the length of the medial callosity. According to Monné (2005), species of Coccoderus do not have records in the phytogeographic domain of the Caatinga. The new species is described from Caatinga biome.
