Fig. 4A–C

Diagnosis

Species very similar to A. parapsidalis , from which can be distinguished by having smooth pronotum with only some short carinae in its lower region (pronotum strongly carinate in all its surface in A. parapsidalis ). It is also very similar to the Nearctic species A. melanoneura , except for having alutaceous and more strongly areolate scutellum, a complete median carina in the propodeum and placodeal sensilla starting at F1 (in A. melanoneura , the scutellum is smooth and not so strongly areolate, the median propodeal carina is incomplete and placodeal sensilla start at F2).

Etymology

The specific name was chosen to honor the British entomologist N. Fergusson, who systematized the confusing information on European Anacharitinae .

Description

LENGTH. Body: 2.9 mm. Antennae: 2.3 mm (♀), 2.5 mm (♂). Wings: 2.8 mm.

COLORATION. Head, mesosoma and metasoma black. Mandibles yellowish brown with darker teeth. Antennae brown with black first segment. Legs yellowish brown, upper femur and coxae darker. Veins of wings brownish.

HEAD. Triangular-shaped in anterior view. Face smooth, covered with abundant white setae. Width of head 1.3 times its height in anterior view and 2.4 times its length in dorsal view. Malar sulcus coriaceous, 0.7 times height of compound eye. Transfacial line length 1.1 times height of compound eye. Diameter of the toruli shorter than inter-toruli distance, but bigger than torulus to compound eye distance. Clypeus shortly defined, convex, densely covered by facial pubescence. Occipital and postocular carinae absent. Compound eyes glabrous. In both sexes POL:OOL:LOL ratio = 7:5:3, ocelli diameter being 3. Frons and occiput smooth covered by some scarce hyaline hairs, gena densely pubescent.

ANTENNAE. Cylindrical flagellomeres covered with pubescence. Female antennal formula: 8(3), 3(2.5), 11(2), 9(2), 8(2), 8(2), 8(2), 7.5(2), 6.5(2), 6.5(2), 6(2), 5.5(2), 9.5(2). Male antennal formula: 9(3), 3.5(3), 10.5(2.5), 9(2.5), 9(2.5), 8(2), 8(2), 7.5(2), 7.5(2), 7(2), 7(2), 7(2), 6(2), 7(2). Placodeal sensilla starting at F 1 in both sexes ( Fig. 4C ).

MESOSOMA. Pronotum alutaceous, densely pubescent, slightly coarse in most of its surface, presence of some short carinae in its ventral region ( Fig. 4B ). Mesoscutal width 1.2 times its length in dorsal view. Mesoscutum smooth, shiny, almost glabrous except for a few lateral short setae; weak alutaceous sculpture at base of notauli ( Fig. 4A ). Notauli complete with strong transverse carinae; median mesoscutal furrow short but distinct. Parapsidal signum short; parascutal sulcus present, internally carinate, being more distinct in anterior mesoscutum ( Fig. 4B ). Scutellar length 0.6 times that of mesoscutum in dorsal view. Scutellum alutaceous, shiny, completely areolate ( Fig. 4A ). Scutellar foveae rounded, smooth, without any internal carinae, basally defined by a carina; lateral pits of scutellar foveae present but superficial. Interfoveal line present. Circumscutellar carina complete, clearly defined, not dorsally projected at scutellum apex. Mesopleuron glabrous, shiny, with internally carinate transverse groove, presence of more or less extended coarse sculpture in anterior mesopleuron which may not be present in some cases. Mesopleural triangle densely covered by long hyaline hairs. Metanotal troughs densely pubescent. Propodeum heavily alutaceous, pubescent; central area longitudinally divided in two symmetrical areas by median carina; both areas are further divided by short transverse carinae in one big upper cell and two smaller cells.

WINGS. Pubescent. Radial cell of forewing closed, 2.7 times as long as wide. Marginal pubescence of forewing denser at apical third.

METASOMA. Longer than head + mesosoma. Petiole about 2.0 times as long as metacoxa, smooth and shiny. Third metanotal tergum 2.1 times as long as fourth tergum in dorsal view. Fifth, sixth, seventh metanotal terga visible in dorsal view. Metanotal terga smooth and glabrous, punctate in anterior region of each tergum, more distinct from T4 to T7.

Taxonomic remarks

After examining large series of material, we have concluded that although most Anacharitinae species show a substantial degree of intraspecific variability in their body sculpture, the difference regarding the pronotal sculpture between Anacharis fergussoni sp. nov. and A. parapsidalis is greater than the variation among the individuals of each species, thus supporting A. fergussoni sp. nov. as a new species.

Biology

Unknown.

Distribution

Palaearctic. Collected from Spain, Andorra, France, Germany, Slovakia, Hungary, Romania and Norway.
