(Figs 5–16)  
 Type material. Holotype ♀: CHINA, Xishuangbanna Tropical Botanical Garden, 20.iii.2003, W. Q. Zhen leg., ex Ficus microcarpa. Deposited in Institute of Zoology, Chinese Academy of Sciences. Paratypes: 6♀, 7♂, same data as holotype.   
 Description. Female (Figs 5–10). Body length 1.9–2.4mm. Head and mesosoma dark, black with faint metallic sheen; mandible yellow with teeth red; antenna with scape yellow, pedicel and anelli yellowish-brown, flagellum dark brown; fore and midcoxae and femora nearly black, lower part of hind coxae almost light yellow; hind femur and all tibiae and tarsi yellow; metasoma dark brown.   
 Head. In frontal view (Fig. 7) slightly higher than wide (73:70); head width and oral cavity width in ratio of 70:45; face and mandibles with white setae; scrobes indistinct; clypeus protruding, black, sides indistinctly delimited. Head in lateral view (Fig. 8) higher than long (27:17); malar sulcus complete; malar space, eye height and eye width in ratio of 3:5:4. POL longer than OOL (21:12). Antennal segments (Figs 7, 9) with long setae except anelli; scape claviform, shorter than pedicel+flagellum (35:50), approximately 8 times as long as wide and 5 times as long as pedicel; funicular segments compact, each slightly wider than long; clava as long as the last three funicular segments combined.   
 Mesosoma. Mesonotum (Fig. 6) with several irregular, outstanding setae. Length of pronotum, mesoscutum and scutellum approximately in ratio of 5:14:17; width of pronotum to mesoscutum in ratio of 4:5; pronotal collar edge with a line of setae; mesoscutum broader than long (35:19); notauli composed of irregular punctures. Scutellum longer than wide (73:70), subacuminate, with 5 or 6 setae. Upper and lower mesepimeron with imbricate reticulation. Fore wing (Fig. 5) length to width in ratio of 8:3; submarginal, marginal and stigmal veins in ratio of 80:15:17. All tarsi with abundant setae.   
 Metasoma. Longer than mesosoma (35:50); in dorsal view with seven tergites, the sixth longest; all tergites and ovipositor sheath with thin, evenly distributed setae. Ovipositor sheath moderately produced (Fig. 5).   
 Male (Figs 11–16). Body length 1.5–2.2mm. Body fragile and soft, meshlike coriaceous, mainly yellowish, sometimes with testaceous spot on propodeum, and on tergites (Figs 12, 15). Antenna with pedicel and flagellum, and wing veins brown. Head with long setae, thorax with black bristles. Structure mostly similar to female, but scrobes distinct, flagellar segments loose, clava not distinct, notauli as linear grooves, and proportions different: head in frontal view wider than high in ratio of 13:11; scape and pedicel length in ratio of 21:9; scape length to rest of antenna in ratio of 21:45; malar space to eye height in ratio of 23:13; length of pronotum, mesoscutum and scutellum approximately in ratio of 5:15:20; width of pronotum to mesoscutum in ratio of 3:4; and in lateral view metasoma approximately as long as mesosoma.   
 Etymology. The specific epithet is from the Latin word root “costallifer” (ridgy), referring to the sharp longitudinal carina present between the toruli, an important character of the genus Sirovena.

 Type material. Holotype ♀: Christmas Island, 1939–1940, C.A. Gibson-Hill leg. Deposited in The Natural History Museum, London. Paratypes: 4♀, same data as holotype.   
 Redescription. Female. Body length 1.5–2.1mm. Head and mesosoma brownish black, without greenish tinge; antenna brown; legs mostly light yellow; metasoma dark brown.   
 Head. In frontal view (Fig. 2) slightly wider than high (71:69); head width and oral cavity width in ratio of 93:50; clypeus protruding, testaceous, sides distinctly delimited by dorsally convergent grooves. Head in lateral view higher than long (40:27); malar sulcus complete; malar space, eye height and eye width in ratio of 10:22:15. POL longer than OOL (20:12) (Fig. 3). Antennal segments with setae except anelli; scape claviform, shorter than pedicel+flagellum (25:35), approximately 8 times as long as wide and 5 times as long as pedicel; funicular segments compact, each slightly wider than long; clava as long as the last three funicular segments combined.   
 Mesosoma. Mesonotum (Fig. 3) with several irregular, outstanding setae. Length of pronotum, mesoscutum and scutellum approximately in ratio of 2:7:12; width of pronotum to mesoscutum in ratio of 5:6; mesoscutum broader than long (36:14); scutellum longer than wide (95:90), with about 3 pairs of dark, outstanding hairs. Upper mesepimeron mostly glabrate, lower mesepimeron with imbricate reticulation (Fig. 4). Fore wing (Fig. 1) length to width in ratio of 8.0:3.4; submarginal, marginal and stigmal veins in ratio of 55:10:13.All tarsi with abundant setae.   
 Metasoma. Longer than mesosoma (40:55); in dorsal view with seven tergites, the sixth longest; all tergites and ovipositor sheath with thin, evenly distributed setae; hypopygium rather large, ending beyond middle of gaster. Ovipositor sheath apex upturned (Fig. 1).
