Lucena, Daercio A. A., Almeida, Eduardo A. B. & Zanella, Fernando C. V., 2021, Amiseginae and Cleptinae from northeastern Brazil, with the description of four new species (Hymenoptera, Chrysididae), Journal of Hymenoptera Research 81, pp. 57-85 : 57

Cleptidea nordestina Lucena sp. nov.

Fig. 7

Diagnosis.

Head bicolored, mostly dark green extending from vertex until upper half of face, mid face to malar area orange; clypeus raised and square-shaped, with lower margin straight; scutum, scutellum and metanotum testaceous; propodeum entirely black, except for the whitish tip of lateral angle. Cleptidea nordestina sp. nov. most resembles C. fasciata (Dalman). The new species can be readily distinguished from C. fasciata by the following combination of unique characteristics: bicolored head, hyaline marks at body (especially trochanters, pronotum, and propodeal angles), clypeus produced, orange metanotum, and entirely black propodeum.

Description.

Holotype, female. Body length: 6.7 mm (Fig. 7A ).

Head: 1.2 × wider than high; toruli 0.9 × MOD separated; scape more or less cylindrical, broader apically, 3.4 × longer than its maximum width; F1 length 3.1 × breadth, 3.1 × longer than F2; F2-F10 sub-equal in size, slightly flattened ventrally, F8-F11 excavated ventrally, F11 acute apically, slightly longer than F10; clypeus protruded medially, squared lobe, with lower margin slightly convex; malar space about 0.6 × MOD; ocelli set in compact triangle on vertex, with transverse sulcus linking laterals; posterodorsal border of eye surpassing lateral ocellus dorsal limit; inner ocular margin sub-parallel, slightly convergent above; LID 1.1 × eye height; eye height 1.5 × breadth; OOL 2.3 × OL, 2.6 × POL; frons with short longitudinal sulcus below median ocellus briefly interrupted.

Mesosoma: pronotum crossed antero- and submedially by transverse crenulate grooves, longitudinal sulcus culminating in a deep fovea posteriorly (Fig. 7H ); posterior margin of pronotum slightly elevated, posterolateral lobe touching tegula; scutum with notaulus deeply impressed, parapsidal line discrete, faintly marked; disc of metanotum slightly convex, marginal areas depressed, posterior margin with pair of small medial pits (Fig. 7G ); M with first abscissa more or less straight, diverging at 1cu-a; costal cell wider distally, about 2.2 × the maximum width of C; dorsum of metacoxa with distinct longitudinal carina; lateral angle of propodeum short, thumb-like.

Metasoma: posterior margin of S1 distinctly concave medially; posterior margin of S2-S4 slightly convex.

Coloration: head basally orange, extending from malar area to mid face, paler basolaterally, metallic dark green hue extending from upper half of face to vertex and gena (Fig. 7B ); scape, pedicel and F1-F2 orange; F3-F11 brownish orange, paler ventrally; pronotum predominantly orange, paler on lobe; disc of scutum testaceous, becoming gradually orange laterally (Fig. 7C, D ); scutellum and metanotum orange; legs yellowish orange, paler on trochanters and ventrally on coxae; tegula orange; wing membrane dusky-hyaline, with broad brownish band submedially, veins brown; metapleuron-propodeum black, tip of lateral angle of propodeum white; metasoma mostly yellowish orange, T1-T3 with broad dark brown bands (Fig. 7E, F ); T4 predominantly yellowish; sterna most yellowish orange, anterior S1 and posteromarginal borders of S2-S3 brown; S4 orange.

Sculpturing: head heavily sculptured, densely punctate, rugulose-lacunose, particularly on vertex and frons, becoming sparser on gena, and impunctate basally near torulus and clypeus; pronotum, scutum and scutellum mostly rugulose-lacunose, lobe of pronotum impunctate; mesopleuron faintly costate above, punctate to rugulose-lacunose below; metanotum punctate on disk; femora and tibiae sparsely punctate; dorsum of propodeum heavily carinate forming areolate enclosures, posterior declivity longitudinally crossed by three main carinae, somewhat rugulose in-between; T1 nearly impunctate and polished posteromedially, with sparse tiny lateral punctures; T2 sparsely punctate on disk, marginal areas impunctate; T3-T4 densely punctate on disc, with broad impunctate stripes marginally; S1 and S4 nearly impunctate, with sparse marginal punctures; S2-S3 finely punctate on disk becoming sparser marginally.

Vestiture: head with sparse, long, pale setae on vertex; frons, face, gena and scape with relatively shorter and denser setation; flagellomeres with decumbent dense pale setation; eye with tiny, sparse, sub-erect microtrichia; dorsum of mesosoma with long, sparse, pale setation, longer on venter of mesopleuron; marginal depression of metanotum with patch of pale setae posteriorly; wing membrane entirely setose, with some distinctive, long, erect dark setae inserted proximally; legs with abundant long pale setation, comparatively longer on metaleg; inner surface of tarsi with short, thick setation and short spines irregularly distributed; disc of T1 and T2 glabrous, sparse setation only marginally, T3 and T4 with long dense setae posteriorly, S1 and S4 glabrous, S2 and S3 with long sparse setation; gonapophysis with some erect setae apically.

Male. Unknown.

Host. Unknown.

Material examined.

Holotype: Brazil • ♀; Bahia, Jequié, campus II UESB, Malaise III; 11.v.2007; Silva-Jr. JC & cols; RPSP.

Distribution.

Brazil, BA: Jequié.

Comments.

The holotype is missing distal flagellomeres of the left antenna. The new species is only known from Jequié, located in a transition zone between Atlantic rainforest and Caatinga (Fig. 8C ). Three unidentified male specimens from Maranhão state (06.vii.1987, Möericke, UFES; but no collector nor locality data) are also new records of the genus Cleptidea for northeastern Brazil. These male specimens are poorly preserved (lacking appendices, altered coloration, and their metasomas are collapsed); thus, we could not assign them to C. nordestina sp. nov. confidently or to interpret them as representing yet another new species.

Etymology.

The name refers to the region where the new species was collected, and it is a Brazilian gentile adjective for a person native from the northeastern region.

Political division of northeastern Brazilian states is indicated by white lines A distribution records of Amisega species (one paratype of Amisega similis Kimsey is signed with a question mark-see Discussion) B distribution records of Duckeia species C distribution records of Cleptidea species. Some localities harbor more than one species, which are indicated by dashed circles. Cleptidea fasciata and C. xantha Kimsey, 1986 are only known from the same type locality and both are represented by the same symbol in C (see Discussion).
