Falsocaenia veracruzi Ferreira , new species

( Figs. 1–4 )

Diagnosis. F. veracruzi can be distinguished from other Falsocaenia species by the dark brown elytra with yellow

humeral spots; the pronotum margins, and antennomeres II and at least apex of antennomeres XI also yellow. Description. General coloration dark brown, except humeral spots, pronotum margins antennomeres II and apex of

antennomeres XI, which are yellow ( Fig. 1 ). Interocular distance twice longer than eye diameter. Head prognathous,

mandibles yellowish, hooked. Labrum transverse. Maxillary palp with coloration varying from yellow to dark brown,

with segment II 6 times longer than I; III and IV subequal in length, 4 times shorter than II, that is very long compared to

the others, the last securiform. Antennae serrate, with antennomeres II and XI yellow (females whole yellow, male only

distal half yellow). Pronotum as long as wide, posterior margins slightly divergent, with a longitudinal carina posteriorly

divergent, forming a slender areola ( Fig. 2 ). Prosternum V shaped, with an agglomeration of setae at the posterior

margin. Pro spiracle tubular. Mesoventrite transverse, connected to mesoepisternum by sternopleural plates.

Mesepimeron expanded, with a conspicuous row of setae. Metaventrite convex, rounded, with metadiscrimen complete, reaching posterior margin of mesoventrite. Legs elongate, slender, generally dark brown. Pro- and mesocoxae short, transverse, more or less oval; metacoxae transverse, slender; trochanters tubular, yellow; femora and tibiae clavate, with the basal tip of the yellow. Elytra 5 times longer than pronotum, widened in the posterior 2/3. Male genitalia symmetrical; median lobe 1.5 times longer than phallobase, broadened distally ( Fig. 3 ), with terminal circular enlargement of phallus 1.5 times wider than parameres width in distal third. Phallobase 2.5 times shorter than median lobe, longitudinal suture absent. Female genitalia slender ( Fig. 4 ), coxites 0.5 times longer than styli. Mediobasal projection sclerotized, directed obliquely. Valvifers shortened, basally fused, forming a ventral bridge, with posterior lateral margins divergent.

Length: 6.0 mm. Width (across humerus): 1.8 mm.

Distribution. Brazil: Amazonas state.

Etymology. The species name was given in honor of the author’s grandmother, Vera Cruz Ferreira.

Type material. Holotype 1, ♂: Brasil—Amazonas, Serra dos Porcos, 0º25’N, 69º22’O, VII-1977, Franklin, Moore ( INPA). Paratypes 2, ♀: same data as holotype. Paratype 1, ♀: Brasil—Amazonas, Manaus—Campus INPA, 22/III/1988, Amorim, N. col. ( MZSP).

Taxonomic remarks. F. veracruzi sp. n. (Brazilian Amazonian Forest) resembles F. grisea Kleine, 1951 ( Peru) and F. ecuadorensis Bocákova, 2012 (Equator), differing from the first by the absence of the yellow transverse stripe on elytra and from the latter by having the lateral margins of the pronotum yellow.
