Elampus pulchricollis ( Ducke, 1911)

( Figs 19–24 )

Ellampus (!) (Notozus) pulchricollis Ducke, 1911: 113 , ♀, holotype (type species by monotypy) “ Brazil, Minas Gerais Barbacena 24.x.1905 / Ellampus (Notozus) pulchricollis ♀ Ducke type ” / “ HOLOTYPE Ellampus (Notozus) pulchricollis Ducke 1911 ” (red label), examined [MPEG]; Ducke 1913: 13.

Elampus pulchricollis: Kimsey & Bohart 1991: 169 .

Diagnosis. Female. Marginal area of terga with broad basolateral membranous border. Scapal basin with distinct cross-ridge zone medially. Dorsal surfaces of head, mesosoma and metasoma without definite punctuation. Integument dull, with pulverulent air on vertex, pronotum and scutum. Dorsal surfaces of mesosoma and apical teeth of mandibles without reddish highlights. Metanotum pointed posteriorly. Tarsal claws with two subsidiary teeth. Male. Unknown.

Redescription. Female (holotype). Body size: 4.8 mm ( Fig. 19 ). Coloration: integument primarily metallic green; vertex, pronotum and scutum metallic green with large dull areas ( Fig. 20 ); metasoma metallic green with large membranous whitish borders basolaterally; sterna greenish; wing membrane light with brown veins; femora and tibiae greenish; tarsi brownish. Head: scapal basin with distinct transverse zones of cross-ridging ( Fig. 24 ); scape and pedicel greenish; flagellomeres dark brown; malar space extremely short (about 0.3 × MOD); subantennal space narrow, shorter than 0.5 × MOD; genal fringe well developed; genal region, behind the composed eye, with distinct scratch marks ( Fig. 19 ); upper genal space broad (longer than 2.5 × MOD); posterior genal margin delimited by carina; upper frons with regular and deep punctures; vertex without punctuation; genal space with scarce and widely separated punctures. Legs: fore femur elbowed basally, forming strong ventral keellike projection; tarsal claws with two subsidiary teeth; legs without distinct punctures, except by tiny ones noticed externally. Wings: R1 absent; M strongly arched, arising slightly before at cu–a; Rs short and curving away from distal margin of wing. Pronotum: lower lateral pronotal surface with large and deep fovea; dorsal surface without punctuation, scarce punctures noticed antero and laterally ( Fig. 20 ); integument dull, with pulverulent air ( Fig. 19, 20 ). Mesopleuron: omaulus and scrobal carina very sharp; mesopleural surface coarsely punctuated. Scutum: notauli absent ( Fig. 20 ); dorsal surface without punctuation along scutal area, scarce punctation restricted to posterolateral region; disc with integument dull, with pulverulent air ( Fig. 20 ). Metanotum: pointed posteriorly ( Fig. 22 ); coarsely punctuated. Propodeum: with sharp teeth basolaterally. Metasoma: lateral margins of visible terga with large membranous whitish border ( Fig. 23 ); T3 distal margin with shallow medial notch ( Fig. 21 ) and smooth integument; T1 and T2 with tiny and widely separated punctures, very shiny interspaces; fine punctuation at all metasoma ( Fig. 21 ), larger and deeper on T3, mainly anterolaterally.

Variation. The species is known only from the holotype.

Material examined. Holotype only.

Distribution. Brazil (Minas Gerais) ( Fig. 12).

Remarks. The species is highly morphologically modified and easily distinguishable by the dull integument on vertex, pronotum and scutum. Additionally, Elampus pulchricollis (Ducke) is readily identifiable by the broad basolateral membranous whitish border on lateral margins of visible terga of metasoma.
