Description

Female. 1.9 (small specimens are rare) – 2.5 mm. Rufous, with more or less metallic dark brown colouration on head, lateral mesosoma (mesopleurae) and dorsum of metasoma ( Figure 1 View Figure 1 (a – d)); parascrobal area with white transverse line ( Figure 1 View Figure 1 (d)), scape white, with its base and ventral half to two-thirds dark brown ( Figure 1 View Figure 1 (a,b,d)), pedicel dark brown, F1 – F3 dark brown, F4 and F5 white ( Figure 1 View Figure 1 (d)), occasionally with F4 darker in its basal 1/3 – 1/4 ( Figure 1 View Figure 1 (a,b,d)); legs with fore coxa, fore and mid femora and fore and mid tibiae white to very pale brown, mid and hind coxae, hind femur and hind tibia dark brown to black, tarsi of all legs pale white to pale yellow ( Figure 1 View Figure 1 (a – c)). First dorsal tergum with a wide, posterior white cross-band extending to first sternum and continuing as a broad band in middle of lateral metasoma ( Figure 1 View Figure 1 (a – c)). Fore wing with two dark bands: proximal band near basal hair row and distal band under marginal vein (perpendicular to marginal vein); hind wing hyaline, basally with dark brown triangular patch ( Figure 1 View Figure 1 (d)).

Head convex, 1.3× as wide as high in frontal view ( Figures 1 View Figure 1 (d) and 2(d)); 1.4× as wide as long in dorsal view, subcircular in lateral view ( Figures 1 View Figure 1 (a) and 2(b)). Eye height 4.0× malar space; mouth opening 2.7× as wide as length of malar space ( Figures 1 View Figure 1 (d) and 2(c – e)). Torulus separated from lower clypeal margin by distance 1.2 – 1.3× as long as its diameter ( Figures 1 View Figure 1 (d) and 2(d)). Lower margin of clypeus slightly projecting as a small rectangle; upper margin of clypeus marked off as a line of creasy sculpture ( Figure 2 View Figure 2 (d,e)). Mandible with two teeth and with minutely denticulate truncation ( Figure 1 View Figure 1 (d)). POL slightly (in ratio of about 77:70) longer than OOL ( Figure 2 View Figure 2 (a)). Antenna with scape 4.5 – 5.2× as long as broad, pedicel 1.7 – 1.9× as long as broad. Flagellum widening towards its end: F5 (clava) ~2.0× wider than F1 ( Figure 1 View Figure 1 (d)), F1 about 1.8 – 2.0× as long as pedicel, F2 about 2.5×, F3 1.5×, F4 1.1×, F5 (clava) 1.4×; relative lengths of F1:F2:F3:F4:F 5 in ratio 9:8:7:5:7.

Mesosoma 2.0× as long as broad in dorsal view ( Figures 2 View Figure 2 (a) and 3(b)), 1.9× in lateral view ( Figure 3 View Figure 3 (a)). Pronotum conical, its anterior margin with four large bristles, its collum convex dorsally and this convex area bearing several setae and being delimited by a flange around it ( Figure 2 View Figure 2 (a)). Mesoscutum about 1.5× as wide as long, bearing two pairs of bristles in its mid part and two pairs of bristles on each shoulder; mesoscutellum ~1.2× as long as broad, with distinct sublateral grooves ( Figure 3 View Figure 3 (a,b), arrowed) and with two pairs of strong bristles ( Figures 2 View Figure 2 (a) and 3(a,b)). Metanotum with broad lateral panels and metascutellum (dorsellum) with anterior groove delimited by a flange ( Figure 3 View Figure 3 (a – c)). Propodeum ( Figure 3 View Figure 3 (c)) about ~1.4× as long as broad, ~3.2 – 3.4× as long as metasomal petiole ( Figure 3 View Figure 3 (a)), bearing distinct basal cup, median carina and lateral plicae; propodeal callus with about five setae ( Figure 3 View Figure 3 (a,c)).

Metasoma about 1.8 – 1.9× as long as broad, 1.3× as long as mesosoma. Petiole short, robust, slightly wider than long. First gastral tergum narrowed, the following terga much wider and convex ( Figure 1 View Figure 1 (a – c)). Basal width of syntergum slightly (~1.1×) larger than its length; cerci with two long curved and two shorter setae ( Figure 3 View Figure 3 (d,e)). Ovipositor sheaths short, not protruding ( Figure 3 View Figure 3 (d,e)).

Body (including head) about 1.5× as long as fore wing. Fore wing 2.7 – 3.0× as long as broad; marginal vein slightly (in ratio of about 330:318) longer than submarginal vein; costal cell 12.0 – 13.0× as long as broad; postmarginal vein 1.4 – 1.5× as long as petiolate stigmal vein; longest marginal seta 2.6× maximum width of marginal vein ( Figure 1 View Figure 1 (e)).

Host. Unknown.

Distribution Afrotropical region ( Central African Republic, Gabon, Uganda; habitats depicted in Figure 5 View Figure 5 ).

Etymology

The species is named in honour of the late John La Salle, a friend and colleague, and an international authority on Chalcidoidea as a whole, and on the family Eulophidae in particular.

Comparative diagnosis. The new species is easily distinguishable from S. fasciatus Bouček ( Figure 4 View Figure 4 ) in the colouration of the antennal flagellum: F1 – F3 are dark brown to black and F4 – F5 are white in S. lasallei ( Figure 1 View Figure 1 (a,b,d)), whereas F2 – F4 are dark brown to black, and F1 and F5 are pale brown to creamy in S. fasciatus ( Figure 5c,d View Figure 5 ). The two species may also easily be distinguished by body proportions, shape of dark bands of fore wings and leg colouration: the mesosoma and head are more robust and convex in S. lasallei (body slender in S. fasciatus ), the stripes on fore wing are broader in S. lasallei (fore wing with fine stripes in S. fasciatus ), and the hind femur and tibia are dark brown to black in S. lasallei (they are pale brown to creamy in S. fasciatus ).
