Specific epithet.

Geographical epithet, from the type locality of this species, the Rio Manu in Peru.

Diagnosis.

With the character states of the genus Calleida   , but from the closest Neotropical species markedly characterized by the peculiar combination of the following morphological features: small-medium sized (TL: mm 7.5-8.0); body very elongate, slender and narrow; head ovate-elongate, with genae swollen and abruptly constricted at the neck; pronotum cordiform, with lateral margins deeply sinuate in the posterior third, disc transversely wrinkled and basolateral seta absent; elytra parallel sided, deeply striate, beaded at apex. Head and pronotum dark brown reddish (yellow-rufous in some individuals), contrasting in color with the dark metallic green or cupreous green elytra; antennae reddish yellow; legs rufous, with darkened, blackish brown femora. Abdominal sternum VII with two setae on each side in males (one only, exceptionally, in one examined individual), three (exceptionally four, on one side) setae in females. Male genitalia as in Fig. 9 View Figures 8–10 .

Description.

General features as in Fig. 5 View Figure 5 . Small-medium sized: L: 8.0-8.5 mm; TL: 7.5-8.0 mm.

Color: head, prothorax and pterothorax concolorous brown reddish (rufous in teneral individuals); abdomen brown blackish (rufous in teneral individuals); antennae, trochanters, tibiae, and tarsi uniformly rufous; femora darkened, brown reddish to blackish; elytra dark metallic green or cupreous green, in some individuals with golden reflections.

Luster and microsculpture: Head and pronotum glossy, cuticular microlines mostly effaced; elytra moderately glossy, with mesh pattern transverse, and evident microlines.

Head: elongate, ovate, with deep neck constriction, evident also on the dorsal side; genae swollen, markedly curved and abruptly constricted at the neck, not contiguous with the posterior margin of eyes which are longer than genae and very prominent; frons smooth; frontal furrows superficial, deeply and densely punctate in front; two supraorbital setae on each side.

Prothorax: transverse-cordiform (ratio PL/PW: 0.78), with lateral margins deeply sinuate in the posterior third and constricted to the base. Lateral grooves wide, flattened, punctate; lateral reflection moderate, evident in the basal fourth. Disc convex, with dense, deep transverse wrinkles and sparse, small punctuations. Anterior angles rounded, fully effaced; basal angles obtusely marked, slightly prominent outside. Base beaded, oblique at the extreme lateral margins. One paramedial seta on each side present; basolateral seta absent.

Elytra: elongate and narrow (ratio EL/EW: 2.0), sub-convex, parallel sided; striae markedly impressed, deeply punctate; intervals convex. Post-humeral sinuation very shallow, pre-apical outer callosity absent. Apex beaded. Interval 3 with two small discal and one apical setiferous punctures; umbilicate series of 13 punctures along stria 8, interrupted in the middle.

Hind wings: fully developed.

Legs: short, robust. Tarsomeres of stout form. Metatarsomeres 1-3 flattened, with shallow traces of dorsal grooves; metatarsomere 4 deeply bilobed, its lobes slightly widened and rounded at apex. Tarsal claws denticulate, each with five long teeth on the inner side.

Abdominal sterna: sternum VII with two setae on each side in males (exceptionally one, in one examined individual), three setae in females (exceptionally and asymmetrically four on one side in one examined individual).

Male genitalia: median lobe of aedeagus (Fig. 9 View Figures 8–10 ) small, short, tubular, moderately curved; apex short, rounded distally. Endophallus with a short, curved, and undulate flagellum, not twisted at base, and a small, basal copulatory piece.

Female genitalia: not examined.

Geographical distribution and habitat.

Calleida manuensis   is known so far from the type locality only: Peru, Madre de Dios, Rio Manu, BIOLAT Biological Station, Pakitza, 356 m a.s.l. The specimens of the type series were obtained by insecticidal fog of bamboo, Astrocaryum   and Guadua   in September and October.

Relationships.

Calleida manuensis   , in both external features (general shape of body, disc of pronotum transversely wrinkled, and abdominal sternum VII with two setae on each side in males and three in females) and the characters state of male genitalia (endophallus with a long, bent flagellum and a small basal copulatory piece), seems to be related to C. gounellei   Liebke, 1935 from southern Brazil and Paraguay. From the latter, it is easily distinguishable for the different pattern of color (the pronotum is mostly metallic golden-green in C. gounellei   ), ovate head (much more transverse in C. gounellei   ), and the markedly cordate pronotum (subquadrate, with lateral margins not or slightly sinuate basally in C. gounellei   ).
