Diagnosis.

Ismarus notaulicus sp. n. is similar to I. dorsiger (Haliday, 1831). It differs mainly in the notauli and mesosoma colour pattern: in I. dorsiger notauli completely absent, dorsal part of pronotum yellow, mesopleuron completely yellow; in I. notaulicus sp. n. notauli present with 7 very small pits, dorsal part of pronotum black, mesopleuron brown except upper margin darkened.

Description.

Holotype (Female). Head. Head in dorsal view much wider than long (9:5), subequal to width of mesosoma (Fig. 11 A–B); POL: 6; LOL: 3; OOL: 7 (Fig. 11B); ocelli large, LOL slightly longer than diameter of lateral ocellus (6:5); vertex behind ocelli nearly flat in lateral view; eye large and without setae; frons and temple with few sparse setae; above antennal sockets, face and cheek with few long setae; antenna slightly shorter than body length (14:17); scape and pedicel with scattered setae; A3-A15 with dense and short setae; antennal segments in following proportions (length:width): 16:5; 8:4; 12:3; 12:3.5; 10:3.5; 10:4; 9:4; 8:4; 8:4; 8:4; 8:4; 8:4; 8:4; 8:4; 11:4 (Fig. 11A).

Mesosoma. Pronotum in dorsal view punctate with whitish long setae; pronotal shoulders angled; lateral pronotum predominantly smooth and concave except upper and lower margins with whitish long setae; mesoscutum smooth and convex with pairs of long setae in front of scutellar pit; notauli present with 7 very small pits on anterior margin (Fig. 11C); humeral sulcus deep and short, as long as length of tegula; scutellum smooth and slightly convex, posterior rim rounded (Fig. 11C); anterior scutellar pit small and deep, much shorter than remaining scutellar disc, distinctly crenulate at bottom, median keel absent (Fig. 11C); mesopleuron smooth with deep crenulate line along posterior margin; metapleuron rugose and covered with dense whitish long setae.

Wings. Radial cell completely closed, 2.0 × as long as wide and 0.6 × as long as marginal vein (Fig. 11A).

Legs. Fore and mid legs slender; hind tibiae incrassate posteriorly, its maximum width slightly wider than hind femora (10:9).

Metasoma. Petiole subquadrate, with strong costae dorsally; base of second tergite with several short costae basally and very short median furrow, extending 0.20 × length of second tergite; suture between T2 and T3 obsolete but the following sutures between tergites distinctly impressed.

Colour. Head yellow except whitish mandibles and antennae yellowish-brown except scape and pedicel yellow; mesosoma black except tegulae yellow and lateral pronotum, mesopleuron and metapleuron brown except upper margin of mesopleuron darkened; metasoma yellow except petiole black; legs yellow; wings hyaline, covered with brown setae.

Measurements. Head length 0.29 mm, width 0.55 mm; mesosoma length 0.48 mm, width 0.49 mm; metasoma length 0.58 mm; fore wing length 1.83 mm; body length 1.35 mm.
