Ordo: Hymenoptera
Familia: Chrysididae
Genus: Chrysis
Name
Chrysis woodi Rosa, Proshchalykin & Halada sp. nov. – Wikispecies link – ZooBank link – Pensoft Profile
Material examined
Holotype: ♂, Mongolia: Dornogovi, 65 km SE of Chatan-Bulag, 1020 m alt., 2.VIII.2007, leg. MH (MSNM).
Diagnosis
Chrysis woodi sp. nov. is characterised by the unusual colouration of flagellomeres, yellowish to brownish. Other relevant diagnostic characters are shape of the genital capsule, with different shape of gonocoxae before gonostylus; apical teeth on metasomal T3, aligned and almost subequal in length, with lateral ones slightly longer than the median pair; pits of the pit row on T3 deep, large or confluent; black spots on S2 large, medially fused, covering 2/3 of segment length.
Description
Male. Body length 5.4 mm. Head. Scapal basin weakly concave with microridged median stripe, laterally micropunctate and covered with dense, short, silvery setae (Fig. 5A); brow prominent above scapal basin; uppermost area of the scapal basin distinctly polished; transverse frontal carina weak, straight, placed medially between anterior ocellus and uppermost margin of scapal basin; malar space elongate, 2.0 × MOD, shorter than F1; antenna thin and long, F1 5.0 × times as long as narrowest width; ventral side of F2–F3 lobulate (Fig. 5A and B); brow with confluent punctures, forming radial pattern around anterior ocellus; dense punctures on remaining part of vertex and ocellar area, with narrow and polished interspaces. OOL 1.5 × MOD; POL 2.3 × MOD; MS 2.0 × MOD; relative length of P:F1:F2:F3 = 1.0:1.7:1.1:0.8; subantennal space 1.1 × MOD. Mesosoma. Pronotum short, l/w: 3.3; medial pronotal line [= pronotal groove] short and shallow; pronotum with small punctures (PD ~ 0.2–0.3 × MOD) and micropunctate interspaces; median area of mesoscutum with shallow and small punctures (PD ~ 0.2–0.4 × MOD), with wide, polished interspaces (1-3 PD), denser postero-medially; interspaces mostly polished with few shallow dots; lateral areas of mesoscutum with similar punctation; punctures become denser along tegulae; mesoscutellum with slightly larger punctures posteriorly (PD ~ 0.5–0.6 × MOD) and small punctures on polished interspaces; anterolateral corners of scutellum above scutellar wing fossa expanded, subrectangular apically; metanotum with denser punctures; scutellar-metanotal suture deep, formed by longitudinally elongate foveae; posterior propodeal projections slightly divergent and basally concave; mesopleuron with wide scrobal sulcus and weak episternal sulcus, formed by small, aligned punctures in the upper part. Wings hyaline, with brown veins, tip of radial sector ending about 1.0 × MOD from anterior wing margin, leaving radial cell open. Metasoma. T1 with double punctation, with dense, small punctures (PD~ 0.2–0.3 × MOD) and micropunctate interspaces (Fig. 5F); T2–T3 with similar dense punctures, with polished intervals; pit row with deep, large and partially to fully confluent pits; apical margin of T3 with four short, triangular teeth, lateral ones slightly longer and more pointed (Fig. 5E and F); lateral edge of T3 straight; medial longitudinal carina faint; black spots on S2 elongate, covering about 2/3 of sternum length, medially fused, with posterior margin outcurved (Fig. 5G); apical margin of T3 bordered with narrow brownish, non-metallic rim; sterna covered with whitish short setae; genital capsule as in Fig. 5C, differently shaped compared with other species in this species group (Farhad et al. 2019[1]). Colouration. Body entirely metallic green, with golden or rosy reflections on mesosoma and metasoma and blue pits of the pit row on T3; tegulae metallic green; mandibles light brown medially, metallic green at base. Scape, pedicel and large part of F1 metallic green, following flagellomeres yellowish ventrally and brownish dorsally (Fig. 5A, B and D); legs metallic green, tarsi yellowish, becoming darker distally; sterna metallic green. Female. Unknown.
Etymology
The specific epithet woodi (masculine noun in genitive) is dedicated to Thomas J. Wood (Mons, Belgium), for his continuous help in proofreading the manuscripts of our team.
Comparative diagnosis
Chrysis woodi sp. nov. belongs to the C. varidens group. Other two western Asian species show green colouration and similar habitus in this subgroup: Chrysis brunneamarginata Farhad, Rosa & Talebi, 2019 (known from Iran) and C. reperta Vinokurov, 2010 (known from Kazakhstan). The first species is easily separable by shape of apical margin of T3, without metallic reflections and by shape of genital capsule (see Farhad et al. 2019[1]). The second is separated by shape of apical margin of T3 with wavy median teeth and shape of black spots on S2 with straight posterior margin (vs. median apical teeth acute and arched posterior margin of black spots).
Remarks
Chrysis reperta Vinokurov, 2010 was originally described with the name C. repertus and the name is here emended in C. reperta, being repertus a Latin masculine adjective not in accordance with the gender of the genus Chrysis Linnaeus, 1761.
Distribution
Mongolia (Dornogovi).
Genus Euchroeus Latreille, 1809
