description: Odontofroggatia quinifuniculus Feng & Huang sp. nov.   
(Figs 1 A–D, 2, 3)  
 Type material. Holotype ♀: CHINA, Hainan province, Danzhou city, Chinese Academy of Tropical Agricultural Sciences, 24.IV.2007, collected by G. Feng, ex Ficus microcarpa L., deposited in Institute of Zoology, Chinese Academy of Sciences.   
 Paratypes: 2 ♀ x ♂ (mating, Fig. 2 A), 25 ♀, and 18 ♂: same data as holotype. (2 ♀, 2 ♂ BMNH; 2 ♀, 2 ♂ in Iziko South African Museum, Cape Town; 2 ♀, 2 ♂ in Jean-Yves Rasplus collection, INRA, Montpellier; others in Institute of Zoology, Chinese Academy of Sciences, Beijing.)   
 Etymology. The specific epithet is a combination of the Latin word root “ quin -” meaning “five” and the Latin noun “ funiculus ”. The antenna of females of Odontofroggatia quinifuniculus is uniquely characterized within the genus by having only 5 funicular segments.   
 Diagnosis. Female (Figs 1 A, B): antennal formula 11053, the first funicular segment without or with only 1 or 2 longitudinal plate sensilla, the other 4 funicular segments with one row of longitudinal plate sensilla extending slightly beyond distal margin; toruli separated by distance subequal to torulus diameter; propodeum with two weak sub-median longitudinal ridges in posterior two-thirds connected to two semiround ridges in anterior third that form more or less W-like pattern; metasoma not compressed. Male (Figs 1 C, D): antennal toruli separated by distance equal to one-fourth torulus diameter and situated at clypeal margin; clypeal margin protruding outward, without lobe; head with a longitudinal median keel; petiole approximately 2.5 times as wide as long with lateral tooth.   
 Description. FEMALE (Figs 1 A, B, 2B, 3a, b). Body 1.5 mm, length of head 0.2 mm, mesosoma 0.6 mm, metasoma 0.7 mm.   
 Colour: Body generally yellow, flagellum darker, gastral terga each with transverse sooty band in dorsal view; eyes and ocelli red, fore wings hyaline with veins pale brown.   
 Head: Head wider than high across eyes (4:3); malar space approximately half length of eye; clypeal margin with a medial cleft and 2 wide lobes; mandibles tridentate, the upper one truncated; maxillary palpus 1-segmented with 3 long apical setae; labial palpi obsolete. Antennae inserted in middle of face, well above lower margin of eyes; distance between torulus and inner eye margin about 4.5 times as great as torulus diameter; antennal formula 11053, scape subcylindrical and 3.5 times as long as wide, twice as long as pedicel; pedicel 1.5 times as long as its apical width; funicular segments cup-shaped, slightly wider than long; club approximately as long as the last three funicular segments combined.   
 Mesosoma: Thorax almost glabrous; pronotum shorter than mesoscutum (2:3), glabrous except for 2 dorsal and 6 lateral long setae; notauli complete, with one long seta at middle; posterior margin of middle lobe of mesoscutum wide; lateral lobe of mesoscutum with one long lateral seta; scutellum slightly shorter than mesoscutum, pointed anteriorly; axilla with a single long seta on inner margin; propodeum approximately three-fourths length of scutellum. Fore wing submarginal vein with 5 long setae; submarginal, marginal, stigmal veins approximately in the ratio of 5:1:1. Fore leg: tibial armature consisting of one subapical ventral spur and a row of five axial spines between spur and apex, tarsal segments approximately in ratio 3:2:2:4. Mid leg: tibia with one subapical ventral spur, tarsal segments approximately in ratio 4:2:2:2. Hind leg: tibia with two subapical ventral spurs and two lines of straight spines in dorsal surface, tarsal segments approximately in ratio 4:1:1:2.   
 Metasoma: Gaster ovoid, ovipositor and its valves not protruding; spiracle of sixth gastral tergite small and circular; hypopygium wide and short, with a single long seta on each side of midline, mucro very short and with 2 pairs of long setae near base.   
MALE (Figs 1 C, D, 2C, 3c–e). Length of body 1.8 mm, head 0.3 mm, mesosoma 0.9 mm, metasoma 0.6 mm.  
 Colour: Body yellow; eyes and ocelli red; wings hyaline with veins pale brown.   
 Head: Head wider than high (3:2); ocelli arranged in a 150˚ obtuse-angled triangle; malar space about one-third as long as length of eye; mandibles bidentate, considerably long, curved inwards, and overlapping each other; maxillary palpus 1-segmented, about twice as long as wide; labial palpi obsolete; head with a longitudinal median keel; clypeal margin protruding outward, without lobe; antennal toruli situated at clypeal margin; toruli separated by distance about equal to one-fourth diameter of torulus; antennal formula 11053; scape subcylindrical, approximately 4 times as long as wide and 2.5 times as long as pedicle; pedicle twice as long as its apical width and as long as the first and second funicular segments combined; the first funicular segment longest and the fifth segment widest; club as wide as fifth funicular segment and as long as the last three funicular segments combined.   
 Mesosoma: Pronotum longer than mesoscutum (2:1), with many setae; notauli complete and with 1 pair of long seta along each; scutellum slightly longer than mesoscutum; propodeum slightly shorter and wider than scutellum and with some setae on each lateral margin; wings more densely ciliated than for female; fore wing submarginal, marginal, stigmal veins approximately in the ratio of 6:1:1. Fore leg: tibia with one subapical ventral spur, tarsal segments approximately in ratio 3:2:2:4. Mid leg: tibia with one subapical ventral spur, tarsal segments approximately in ratio 4:2:2:3. Hind leg: tibia with two subapical ventral spurs and many straight spines on dorsal surface; tarsal segments approximately in ratio 3:1:1:2.   
 Metasoma: gaster much shorter than mesosoma (1:2) and dorsoventrally flattened; genital digitus with 3 dark spines.   
 Remarks. The four previously described Odontofroggatia species have an antennal formula of 11063 in females, which was regarded as a stable diagnostic character for the genus (Bouček 1988). However, females of O. quinifuniculus have an antennal formula of 11053, which violates this diagnostic feature. Females of Camarothorax Mayr also have five funicular segments, but they can be differentiated by a malar sulcus, the antennal funicular segments bear a row of strong longitudinal plate sensilla but almost no hairs (Bouček 1988, fig. 234), and the anterior margin of scutellum is at least slightly broader than the hind margin of mid lobe of mesoscutum. Furthermore, the funicle in males is reduced to about 3 segments (Bouček 1988, figs 232, 233; Vincent & Compton 1992).   
 Females of O. quinifuniculus lack an occipital carina, the scutellum is pointed anteriorly, and the tarsi are 4-segmented, which is much more similar to females of Josephiella malabarensis Narendran (1993). However, females of J. malabarensis possess a 11153 antennal formula including a distinct anellus (Narendran & Sheela 1993, fig. 4). Females of another Josephiella species, J. microcarpae Beardsley and Rasplus (2001), have the same antennal formula as O. quinifuniculus, but both the notauli and axillar grooves are much reduced (Beardsley & Rasplus 2001, fig. 3D). Beardsley and Rasplus (2001) also provided other features to differentiate the genera, including Josephiella having a subglobose rather than transverse head, a short scape not reaching the anterior ocellus, and the scutellum having at least 3 pairs of setae. Furthermore, both J. malabarensis and J. microcarpae reared from leaf galls of fig trees (Beardsley & Rasplus 2001; Narendran & Sheela 1993). DNA Barcoding data (unpublished) also supports our new described species being placed into the genus Odontofroggatia.   
 Within Odontofroggatia, O. quinifuniculus is most similar to O. ishii, females sharing a very similar propodeal sculpture pattern (Figs 1 B, F), and males a similar petiolar structure (Figs 1 D, H). Females differ in antennal formula and males in the presence (O. ishii, Fig. 1 G) or absence (O. quinifuniculus, Fig. 1 C) of a clypeal margin lobe and presence (O. quinifuniculus) or absence (O. ishii) of a longitudinal median keel on the front of the head, as well as by DNA Barcoding evidence (unpublished).
