P a r a t y p u s (): with same label (Leiden)

D e s c r i p t i o n of: Body length 15 mm. Flagellum slightly lanceolate, with 43 flagellomeres. First flagellomere (without anellus) 3.0x as long as wide, two basal flagellomeres together 0.75x as long as eye, widest flagellomeres 1.7x as wide as long. Temple roundly narrowed behind eye. Distance of lateral ocellus to compound eye about 1.3x its diameter. Frons smooth, with very few punctures laterally. Face, gena and clypeus with superficial puncture, intervals smooth. Apical margin of clypeus slightly biconcave, with a small median tubercle.

Mesosoma with whitish hairs. Sides of pronotum with small and dense puncture dorsally. Central parts of mesoscutum with coarse puncture, puncture at sides and anterior parts becoming much smaller, granulate. Mesopleurum with fine dense puncture, speculum smooth. Metapleurum with coarse rugulose-puncture. Coxal carina distinct. Scutellum flat, with complete thickened lateral carina, puncture somewhat striate in the apical half. Area basalis and superomedia slender, confluent and finely rugulose, about 3x as long as wide, costula in the middle of area superomedia. Propodeum otherwise with coarse puncture. Coxa III with fine puncture and weak scopa. Femur III with scattered puncture in the ventral third, about 4.6x as long as high.

Areolet almost quadrangular, frontal distance of intercubiti 1x their diameter, nervulus postfurcal.

Metasoma oxypygous. Postpetiole moderately widened, median field smooth, with few punctures. Gastrocoelus large, smooth. Thyridium large, oblique, 1x as wide as the thyri- dial interval. Second tergite 1.1x as long as wide. Tergite 2 with coarse rugose puncture and median striation. Tergites 3-4 with dense fine puncture, median striation on base of tergite 3 only. Ovipositor sheath not extending metasomal apex.

Coloration: Black. Ivory are stripe on flagellomeres 8-16, palps, mandible except teeth, clypeus and face, gena, orbits except two narrow interruptions on vertex, scapus beneath, propleurum, collare and upper margin of pronotum, spot on tegula, subtegular ridge, two short and more reddish median stripes on mesoscutum, lower mesopleurum, prescutellar carina, apex of scutellum, postscutellum, apical margin of metapleurum, spot of area spiraculifera in front of spiracle, area basalis, area posteroexterna, apical band of postpetiolus and subapical bands of tergites 2-3, apical band on tergite 6, tergite 7 completely, coxae I-II, all trochanters, base of coxa III. Leges reddish-yellow. Femur III black, narrowly reddish at base, tibia III black, with subbasal ivory ring. Tarsus III completely black. Pterostigma brownish.

D e s c r i p t i o n of: Body length 16.5 mm. Flagellum with 41 flagellomeres. Long-oval tyloids on flagellomeres 8-21, longest ones as long as their flagellomere. Femur III 3.7x as long as high, with scattered puncture in the ventral third. Second tergite 1.05x as long as wide. Tergites 2-3 with rugulo-puncture and median striation, tergites 4-5 with fine superficial puncture, tergite 4 with some median striae at base. Otherwise structured as the.

Coloration: As in the, with the following differences: flagellum without ivory ring, orbits completely ivory, lower mesopleurum and mesosternum ivory, area basalis black, base and ventral side of coxa III ivory; femur II reddish, infuscate in the apical 0.4. Metasoma black. Base of petiolus and apical band of postpetiolus ivory, tergites 2-3 with apical ivory band (narrowed medially), tergite 4 with posterolateral ivory spots, tergite 5 black, tergite 6 with ivory apical band, tergite 7 completely ivory.

R e m a r k: This taxon differs from the known species of Cratojoppa mainly by the carinated scutellum, black tarsus III, and completely black tergite 5.

D i s t r i b u t i o n: Vietnam.
