Ismarus goodrichi sp. n. Figure 4A− C

Diagnosis.

Ismarus goodrichi sp. n. is similar to I. halidayi Förster, 1850. It differs mainly in the posterior rim of scutellum and furrow on base of T2: in I. halidayi , posterior rim of scutellum rounded and base of T2 with long median furrow, at least to half the length of tergite; in I. goodrichi sp. n., posterior rim of scutellum truncated and base of T2 with short median furrow, extending 0.2 × length of tergite.

Description.

Holotype (Female). Head. Head in dorsal view much wider than long (20:11), slightly wider than width of mesosoma (8:7) (Fig. 4 A–B); POL: 10; LOL: 7; OOL: 8 (Fig. 4B); ocelli large, LOL subequal to diameter of lateral ocellus; vertex behind ocelli nearly flat in lateral view; eye large and without setae; inner orbits, frons and temple with few sparse setae; above antennal sockets, face and cheek with few long setae; antenna much shorter than body length (13:19); scape and pedicel with scattered setae; A3-A15 with dense and short setae; antennal segments in following proportions (length:width): 17:5; 8:4.5; 10:3; 10:3.5; 7:4; 7:4; 7:5; 7:5; 7:5; 7:5; 7:5; 7:5; 7:5; 7:5; 11:5.5 (Fig. 4A).

Mesosoma. Pronotum in dorsal view rugose with whitish long setae; lateral pronotum predominantly rugose punctate except smooth and slightly concave in the middle; mesoscutum smooth and convex with pairs of long setae in front of scutellar pit; notauli present anteriorly, pits merged with the curved notauli (Fig. 4C); humeral sulcus deep and long, much longer than length of tegula (16:11); anterior scutellar pit small and deep, much shorter than remaining scutellar disc, slightly crenulate at bottom, median keel weakly present; scutellum smooth with punctures and slightly convex, posterior rim truncate (Fig. 4C); mesopleuron smooth with deep crenulate line along posterior margin (Fig. 4C); metapleuron rugose and covered with dense whitish long setae.

Wings. Radial cell completely closed, 1.75 × as long as wide and 0.95 × as long as marginal vein (Fig. 4A).

Legs. Fore and mid legs slender; hind tibiae incrassate posteriorly, its maximum width slightly wider than hind femora (9:8).

Metasoma. Petiole short and distinctly expanded (3:5), punctate-rugose dorsally; tergites smooth, with scattered setigerous punctures; base of second tergite with several short costae basally and short median furrow, 0.20 × length of second; sutures between tergites complete and deeply impressed.

Colour. Body black; antennae yellow except A12-A15 brown, tegulae and legs uniformly yellow; wings hyaline, covered with brown setae.

Measurements. Head length 0.46 mm, width 0.80 mm; mesosoma length 0.94 mm, width 0.71 mm; metasoma length 1.04 mm; fore wing length 1.99 mm; body length 2.43 mm.
