Anacharis flavidicornis – Kieffer 1910 (non Anacharis flavicornis Kieffer, 1909 ).

Diagnosis

Species with incomplete notauli and smooth mesoscutum like A. atricornis , A. longicellus , A. paucus and A. zaitzevi , from which can be distinguished by having alutaceous scutellum slightly projected at the end (scutellum areolate and not dorsally projected in A. atricornis , A. longicellus , A. paucus and A. zaitzevi ).

Redescription

MEASUREMENTS. Body: 2.4 mm; antennae: 0.3 mm (♂, scape and pedicel only); wings: 2.5 mm.

COLORATION. Head, mesosoma and metasoma black. Mandibles yellowish brown with darker teeth. Antennae yellow. Leg yellow with brown coxae. Veins of wings yellowish.

HEAD. Triangular-shaped in anterior view, 1.2 times as broad as high, malar area not expanded. Face smooth and punctate, with short uniform pubescence. Malar area coriaceous, 0.6 times as long as compound eye. Clypeus smooth, glabrous and shortly projected; anterior tentorial pits small, indistinct. Transfacial distance as long as compound eye. Diameter of torulus larger than inter-toruli and toruluseye distances. Frons, gena and occiput smooth and glabrous with few sparse setae; occipital and postocular carinae absents. In dorsal view 1.7 times as broad as long, broader than mesosoma. Compound eyes glabrous. POL: OOL: LOL is 8.0:4.5:2.5, diameter of lateral ocellus is 3.5.

ANTENNAE. In males, antenna 14-segmented; flagellomeres cylindrical and pubescent, same width in all flagellomeres, placodeal sensilla abundant in all flagellomeres; F1 not modified; antennal formula (flagellum lost): 6.0(3.0), 3.5(2.5).

MESOSOMA. Pronotal plate smooth. Pronotum punctate; slightly pubescent, some short irregular ventral carinae present. Mesoscutum 1.2 times as broad as long in dorsal view. Mesoscutum smooth to slightly alutaceous, shiny, glabrous. Notaulus incomplete but apparent, effaced at anterior mesoscutum and never internally carinate ( Fig. 3c ); median mesoscutal furrow short and narrow. Lateral mesoscutum punctate; parapsidal signum reduced to a short and narrow groove, parascutal sulcus very tenuous and not internally carinate, presence of a punctate band instead. Scutellum alutaceous and shiny, laterally coarse, 0.6 times of mesoscutal length; scutellar foveae trapezoidal, large, smooth, posteriorly defined by carina; presence of superficial and narrow pit next to inner margin of scutellar foveae.Interfoveal line complete.Circumscutellar carina shortly projected at apex of scutellum ( Fig. 3c ), triangular shape in dorsal view. Anterior and ventral mesopleuron carinate, central and posterior mesopleuron smooth. Mesopleural triangle heavily alutaceous, not pubescent. Metanotal troughs coarsely sculptured and almost glabrous. Lateral propodeum with strong coarse sculpture; central propodeum glabrous, coriaceous, divided in two symmetrical areas by median longitudinal carina; lower central region and rest of propodeal surface divided into smaller cells.

FORE WINGS. Pubescent, marginal pubescence denser at apical third. Radial cell closed, 2.5 times as long as wide. Vein 2rm absent.

METASOMA. Shorter than head + mesosoma. Petiole slightly longer than wide, shorter than metacoxa, coarsely sculptured, shiny. Third metasomal tergum 2.9 times longer than fourth in dorsal view. Metasomal terga smooth and glabrous; T4 to T7 punctate.

Biology

Unknown.

Distribution

Palaearctic. China: Xinjiang Uyghur Autonomous Region ( Kieffer 1910), Beijing ( Mata-Casanova et al. 2015b).

Comments

Kieffer (1909) described an American species of Anacharis as A. flavicornis . One year after, another species of Anacharis was described from Chinese Turkestan with the same denomination ( Kieffer 1910). The author changed the homonymy one year later as part of a revision and correction on the names of different species of Cynipoidea and Evanoidea ( Kieffer 1911), thus resulting in one American species, A. flavicornis Kieffer, 1909 , and one Palaearctic species, A. flavidicornis Kieffer, 1911 .

When studying the type of Anacharis flavidicornis , it did not present the typical features of the genus Anacharis but Aegilips instead, being recombined into Aegilips flavidicornis ( Mata-Casanova et al. 2018) .
