The specific name, Calleida anomala , indicates the unique features of this new species into the genus, i.e., the absence of the paramedial (anterior) seta of the pronotum, and the peculiar shape of head and pronotum.
With the character states of the genus Calleida (in the wider sense: see Materials and methods), but from the closest Neotropical species markedly characterized by the peculiar combination of the following morphological features: small-medium sized (TL: mm 7.1-8.5); body moderately elongate, depressed; head subquadrate, with genae very swollen and abruptly constricted at the neck; pronotum transverse-cordiform, with lateral margins markedly sinuate in the posterior third and paramedial seta absent; elytra slightly widened at the apical third, deeply striate, beaded at apex. Head, pronotum, underside and legs dark brown to blackish, moderately contrasting in color with the dark metallic green, blue green, blue violet, or violet elytra. Abdominal sternum VII with one seta on each side in males, two setae in females. Abdominal sternum IX as in Fig. 10C View Figures 8–10 . Male genitalia as in Fig. 10A, B View Figures 8–10 .
Color: Head, prothorax and pterothorax concolorous dark brown to blackish; mandibles and palpomeres at apex, and antennomeres 1 and 2 dark reddish; following antennomeres markedly darkened at apex and on the dorsal side; abdominal sterna 4-7 blackish, each with a dark reddish spot at sides; elytra dark metallic green, blue green, blue violet or cupreous violet.
Luster and microsculpture: head and pronotum glossy, cuticular microlines mostly effaced; elytra moderately glossy, with mesh pattern transverse, and evident microlines.
Head: subquadrate, with deep neck constriction; genae swollen, markedly curved and abruptly constricted at the neck, not contiguous with the posterior margin of eyes which are longer than genae and prominent; frons smooth; frontal furrows elongate, with deep longitudinal wrinkles and sparse punctuations; two supraorbital setae on each side.
Prothorax: transverse-cordiform, slightly wider than long (ratio PL/PW:0.82), with lateral margins markedly sinuate in the posterior third and constricted to the base. Lateral grooves wide, punctate, widened and flattened in the posterior two/thirds; lateral reflection moderate, evident in the basal fourth. Disc moderately convex, with dense, deep transverse wrinkles. Basal foveae deep, punctate. Anterior angles rounded, fully effaced; basal angles right. Base straight, completely beaded. Paramedial seta at sides absent; basolateral seta on each side present.
Elytra: moderately elongate (ratio EL/EW: 1,7), depressed, slightly widened at the apical third; striae impressed, punctate; intervals convex. Post-humeral sinuation very shallow, pre-apical outer callosity slightly distinguishable on interval 8. Apex beaded. Interval 3 with two small discal and one apical setiferous punctures; umbilicate series of 13 large, foveate punctures along stria 8, interrupted in the middle.
Hind wings: fully developed.
Legs: elongate. Meso- and metatibiae markedly curved; tarsomeres of stout form. Metatarsomeres 1 and 2 flattened, with evident dorsal grooves; metatarsomere 4 deeply bilobed, its lobes markedly widened and rounded at apex. Tarsal claws denticulate, each with five long teeth on the inner side.
Abdominal sterna: abdominal sternum VII with one seta on each side in males, two setae in females. Abdominal sternum IX as in Fig. 10C View Figures 8–10 .
Male genitalia: median lobe of aedeagus (Fig. 10A, B View Figures 8–10 ) very small, stout, moderately curved; apex short, rounded distally. Endophallus with two elongate, bent and basally connected pieces; dorsal piece longer than the ventral one, and more sclerotized.
Female genitalia: not examined.
Geographical distribution and habitat.
Calleida anomala 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 mostly by insecticidal fog of bamboo, in September and October.
Calleida anomala is very isolated into the genus owing to some unique and peculiar morphological characters, i.e., the absence of paramedial (anterior) seta at sides of pronotum and the general features of head and prothorax. However, for some features such as the small-medium sized body, and the abdominal sternum VII with one seta on each side in males, two setae in females, it should be related to a large group of species widely distributed mostly in Venezuela and Brazil (many of them undescribed), including C. similis Reiche, 1842, C. subaenea Mannerheim, 1837, and C. purpuripennis Chaudoir, 1872.
