Atlanticolycus camposgerais sp. nov.

( Figs. 1–2 , 7–8, 17 )

Type material. Holotype, male, BRAZIL: BRASIL, PR, Ponta Grossa; Parque Nacional dos Campos Gerais ; - 25,101; 49973; 14-15.xi.2015; Nascimento, E.A., Biffi, G., Prado, L. R., Ray, A. col. ( DZUP) . Paratypes: same data, 1 male, 1 female ( DZUP) .

Diagnosis: Eye diameter 1.7× longer than interocular distance. Maxillary palpomere 2 almost twice longer than 3. Pronotum 1.3× wider than long, median longitudinal carina at apical 1/3 bifurcating medially forming areola mostly at posterior 2/3, connected to the posterior margin by a very short carina ( Fig. 1 ). Elytra dark brown with median transversal band yellow increasing in thickness towards marginal costae ( Fig. 2 ). Phallus curved in lateral view, apex with sharp and slightly curved apical dorsally-oriented projections and apex almost conical ventrally-oriented ( Fig. 7a, b ); parameres medially constricted in ventral view ( Fig. 8 ), apically rounded with three ventral subapical thorns ( Fig. 7c ).

Description: Maxillary palpomere 1 and basal half of palpomere 2 yellow. Trochanters yellow, basal 1/4 of median femur yellow. Pronotum dark brown with lateral sides and anterior margin yellow ( Fig. 1 ). Elytra dark brown with humeral portion yellow, and a median transversal band yellow increasing in thickness towards marginal costae ( Fig. 2 ).

Eye diameter 1.7× longer than interocular distance in male. Male antennomeres 3−5 almost of the same length. Maxillary palpomere 2 as long as 4 and almost twice longer than 3. Pronotum 1.3× wider than long, median longitudinal carina bifurcating in anterior 1/3 forming areola mostly at posterior 2/3, connected to posterior margin by a very short carina ( Fig. 1 ). Prosternum trapezoidal, mesoventrite trapezoidal. Elytra 4× longer than humeral width in male, 3.7× longer than humeral width in female, and intercostal intervals with irregular cells. Hind femora 3× longer than trochanter length. Male genitalia with short phallus, curved in lateral view, strongly bent dorsally, with sharp and slightly curved apical dorsally-oriented projections ( Fig. 7a ) and apex almost conical ventrally-oriented ( Fig. 7b ); parameres elongate, 1.1× longer than phallus length, ventrally bent towards the apex in lateral view, medially constricted in ventral view, apically rounded with three ventral subapical thorns ( Fig. 7c ) and joined basally by a ring-like bridge, phallobase slightly asymmetrical and as long as half of parameres length ( Figs. 7–8 ). Female genitalia with short valvifers forming thin ventral bridge, coxites long, medially arcuately emarginate, styli as long as valvifers ( Fig. 17 ). Body length: 6.3−6.8 mm (males), 6.0 (female), humeral width: 1.5−1.6 mm (males), 1.4 (female).

Etymology: The specific name is a noun in apposition taken from the type locality, Campos Gerais National Park.

Distribution: Brazil: Southern region, Paraná state, Ponta Grossa municipality ( Fig. 19 ).
