Diagnosis

Chrysidea pumiloides is characterized by the combination of the following characters: TFC absent; head wide, 1.3–1.4 × as wide as high; distal margin of T3 with large, triangular lateral teeth and area between rounded; MS = 0.6–0.8 MOD; tegula brown with more or less strong blue to purple reflection; mesoscutellum with impunctate area; metanotum rounded, without anteromedian pit; T2 with microreticulate interspaces among punctures; male genitalia with distal apex of paramere flat.

Description

Female

BODY LENGTH. 3.8–4.8 mm.

HEAD. Width 1.3–1.4 × as wide as high. Scapal basin deep, transversely wrinkled and punctate with sparsely located minute punctures. TFC absent ( Fig. 1B ). Antennomeres P, F1, F2, F 3 in the following proportions: 1.2–1.7, 1.0–1.8, 0.7–1.0, 1.0–1.2; F1 l/w = 1.5–1.9; OOL = 1.3–1.5 MOD; POL = 1.7–1.9 MOD; MS = 0.6–0.8 MOD; apical margin of clypeus slightly concave; mandible edentate; basal width of mandible = 1.1 MOD. Brow and vertex punctate-reticulate; punctures on brow irregular and slightly larger, PD: 0.5–0.6 MOD ( Fig. 1B ).

MESOSOMA. Pronotal groove shallow and indistinct, extending ⅔–¾ length of pronotum. Notauli deep, complete; parapsidal lines indicated by smooth strip. Mesoscutellum almost flat. Metanotum rounded, separated from mesoscutellum by deep furrow, large anteromedian pit absent. Pronotum, mesoscutum and metanotum densely punctate, almost punctate-reticulate: punctuation on surface between notauli sparser, 0.2–0.5 PD apart in a female labeled “No. 66” (ELKU); base of punctures flat, margin keenly edged; mesoscutellum densely or sparsely punctate, dorsal surface with smooth impunctate area ( Fig. 1C ): smooth area narrower in a female from Antsingy (MNHN). Episternal sulcus and scrobal sulcus distinct, formed by large foveae. Metanotum without anteromedian pit, rounded in lateral view. Forewing weakly infuscate with discoidal cell incomplete, outer veins not pigmented ( Fig. 1A ).

METASOMA. Median line absent or faintly present on T1 and T2 ( Fig. 1D ). Punctures on T1 0.2–0.4 MOD, almost punctate-reticulate with smooth interspaces; punctures on T2 and T3 smaller, sometimes indistinct, 0.15–0.3 MOD, with granulate interspaces: interspaces almost smooth, only faintly granulate in a female from Antsingy (MNHN); pre-pit row area of T3 weakly bulged; pit row distinct, with deep pits. Apex of T3 with a pair of lateral dully teeth, interval between teeth rounded ( Fig. 1F ). S2 ( Fig. 1E ) black spots oval and medially separated by 0.8 MOD.

COLORATION. Head metallic blue-green to blue, sometimes purplish, face more greenish. Antenna dark brown with scape, pedicel, F1 and F2 metallic blue-green or blue: F1 and F2 of holotype almost dark brown. Mandible testaceous, basal ⅓ metallic blue-green, apex reddish dark brown. Mesosoma metallic blue-green, sometimes surface between notauli darkened: surface of holotype blackish with purplish luster. Tegula brown with strong purple reflection; reflection weaker, more brownish in smaller specimens and more bluish in female from Antsingy. Legs brown, with strong purplish reflection and green luster on coxae and femora: hindcoxa of a female from Behara (NHMW) metallic green; tibiae brown with greenish reflection, sometimes bluish; tarsi brown. T1 metallic blue-green, sometimes purplish, more greenish laterally and posteriorly; T2 metallic blue with purplish luster, greenish or bluish without purplish luster laterally and posteriorly; T3 metallic purple, bulged pre-pit row area usually bluish. Sterna metallic blue-green to green.

Male

Body length 3.0 mm. Similar to female ( Fig. 2 A–B). Head 1.5 × as wide as high ( Fig. 2B ); tegula more brownish, bearing only a slightly purplish luster ( Fig. 2C ), metasoma more darkened ( Fig. 2D ): T2 and T3 largely dark purple; distal apex of T3 broken in the only known male specimen ( Fig. 2F ). Antennomeres P, F1, F2, F 3 in the following proportions: 1.3, 1.0, 0.7, 0.7; F1 l/w = 2.0; OOL = 1.5 MOD; POL = 1.6 MOD; MS = 1.0 MOD; S2 black spots ( Fig. 2E ) semicircular, anterior margin substraight, 1.6 MOD apart each other. Paramere ( Fig. 9A ) with inner margin rounded, distal apex flat; aedeagus wide, laterally not exposed.

Distribution

North and south Madagascar.

Biology

Unknown.

Remarks

According to Zimmermann (1956), a paratype female should be deposited at the Musée royal du Congo belge, Tervuren, Belgium (Royal Museum for Central Africa), however, no material of C. pumiloides was found (S. Hanot, Royal Museum for Central Africa, pers. com.). On the other hand, there is a female of C. pumiloides with a type label in NHMW, but it should not be the true paratype because the specimen is incongruent with the original description and the collection locality is Annarivo (= Antananarivo?) instead of Bekily, as given in the original description. In NHMW, we found similar erroneous type labels pinned with other chrysidids, including another Chrysidea : a specimen labelled as “type” of C. phoebe Zimmermann, 1956 , which is conversely described on a single holotype specimen deposited in MNHN, without paratype designation.

Linsenmaier labelled a female from Antsingy (MNHN) as type of Chrysidea planipunctata , but it remained unpublished. The body color appears more greenish compared to the holotype female of C. pumiloides , however, other important morphological characters are indistinguishable. The color could be variable from more bluish, like a female from Behara (NHMW), to greenish, like a female from Antsingy and females and a male labeled “No. 66” (ELKU).
