Chrysidea pumiloides – Bohart 1988: 130 (key, partim).

Diagnosis

Chrysidea vazimba sp. nov. is characterized by the combination of the following characters: TFC present; metatarsus basally light brown to yellowish; head wide, 1.3 × as wide as high; distal margin of T3 with large, strong (female) or rounded (male) lateral teeth and rounded interval; MS = 0.7 MOD; tegula with strong blue-green reflection; second metasomal tergum without microreticulate punctation.

Etymology

Chrysidea vazimba sp. nov. is named after the name of the first inhabitants of Madagascar, according to popular tradition.

Description

Female

BODY LENGTH. 5.6 mm.

HEAD. Width 1.3 × as wide as high. Scapal basin deep, transversely wrinkled and punctate, with sparsely located minute punctures. TFC present above scapal basin, substraight ( Fig. 3B View Fig ). Antennomeres P, F1, F2, F 3 in the following proportions: 1.3, 1.8, 1.2, 1.2; F1 l/w = 1.9; OOL = 1.8 MOD; POL = 2.1 MOD; MS = 0.7 MOD; apical margin of clypeus almost straight, faintly concave; mandible edentate; basal width of mandible = 1.6 MOD. Brow with large, irregular and longitudinally contiguous punctures; punctures above TFC deeper, PD on brow: 0.5–0.7 MOD ( Fig. 3B View Fig ).

MESOSOMA. Pronotal groove shallow and indistinct, extending ½ length of pronotum. Notauli deep, complete; parapsidal lines indicated by smooth strip. Mesoscutellum weakly rounded. Metanotum humped (as in Fig. 4A View Fig ), separated from mesoscutellum by deep furrow, large anteromedian pit present ( Fig. 3C View Fig ). Mesosoma entirely punctated by deep, coarse and irregularly sized punctures; pronotum mesoscutum, and mesoscutellum with densely located large and fewer small punctures: largest punctures 0.6 MOD. Episternal sulcus and scrobal sulcus distinct, formed by large foveae. Forewing with discoidal cell indistinct, outer veins faintly pigmented but apparently weaker and not tubular as other pigmented veins ( Fig. 3A View Fig ).

METASOMA. Median line faintly present on metasomal terga ( Fig. 3D View Fig ). Punctures on T1 0.2–0.4 MOD, densely located each other, interspaces with minute punctures; punctures on T2 and T3 smaller, 0.2–0.3 MOD, with interspaces smooth; pre-pit row area of T3 bulged; pit row distinct, with large and deep pits. Apex of T3 with a pair of acute lateral teeth, interval between teeth rounded ( Fig. 3F View Fig ). S2 ( Fig. 3E View Fig ) with black spots oval and medially separated by 0.6 MOD.

COLORATION. Head metallic blue-green. Antenna dark brown with scape, pedicel and F1 metallic blue-green. Mandible testaceous, basal ⅓ metallic blue-green, apex reddish dark brown. Mesosoma metallic blue-green, with mesoscutum between notauli blackish, propodeum bearing purplish luster. Tegula brown with marked blue-green reflection. Legs greenish with purplish coxae, tarsi dark except metatarsus basally light brown to yellowish. T1 metallic blue-green, more greenish laterally and posteriorly, T2 metallic green-blue, more greenish posteriorly, behind posterior margin of T1 with black and purplish narrow bands; T3 basally blackish, apically metallic violet, bulged pre-pit row area bluish. Sterna metallic green.

Male

Body length 4.2 mm. Similar to female ( Fig. 4 View Fig A–B) but different as follow: body slightly more greenish; lateral teeth on T3 rounded ( Fig. 4D, F View Fig ); S2 black spots ( Fig. 4E View Fig ) reniform; paramere with inner margin substraight ( Fig. 9B View Fig ); aedeagus strongly narrowed apically ( Fig. 9B View Fig ).

Distribution

Madagascar.

Biology

Unknown.

Remarks

The type locality name “Annanarivo” is ambiguous. It might indicate an area near Antananarivo, northeast of the capital city, or even a larger undefined area. The body color of Chrysidea vazimba sp. nov. is similar to that of C. pumiloides , but is easily distinguished by the presence of one TFC ( Figs 3B View Fig , 4B View Fig ) and humped metanotum. Morphological characters are rather similar to C. rhodopis Zimmermann, 1961 ; however, in C. vazimba sp. nov., interspaces among punctures on T2 are smooth and black spots on S2 are more rounded and more closely located each other ( Figs 3E View Fig , 4E View Fig ).
