Type material. HOLOTYPE. ♀ (deposited in AMNH) with the following labels: “ MEXICO, Ciudad de Mexico, Ciudad de Mexico ” (white label), “ Q. crassipes, (01.xii.1932) leg. Kinsey ” (white label); Holotype Amphibolips kinseyi Cuesta-Porta & JP-V n. sp., desig. Cuesta-Porta, 2020” (red label).
Etymology. Named in honor of Alfred C. Kinsey (1894–1956) who greatly contributed to the knowledge of Amphibolips and the American cynipid fauna.
Diagnosis. The new species is characterized by incomplete notauli margined dorsally by carinae on posterior half of mesoscutum; mesoscutellum margined laterally by strong carina that emarginate posterior depression of mesoscutellum, both laterally and posteriorly. Most closely resembles A. aliciae by the forewing colouration, notauli emarginate by carina on dorsal side. It differentiate by brown to chestnut head and mesosoma, ambarine metasoma (head and mesosoma black, metasoma rufous in A. aliciae), strongly emarginated mesoscutellum laterally and posteriorly (not emarginate in A. aliciae); frons alutaceous with fine rugae (coarsely reticulate-rugose in A. aliciae). Forewing colouration also resembles those of A. salicifoliae and A. quercuspomiformis comb. nov., but in A. kinseyi n. sp. infuscate area on basal margin of radial cell larger, tarsal claws with basal lobe (claws simple in A. salicifoliae and A. quercuspomiformis comb. nov.). Furthermore, bud galls of the new species are ovate with lignified parenchyma while galls of A. aliciae are fragile, fusiform, internal hollow with radiating filaments supporting the larval chamber. The gall is similar to other species with a large globular shape without mottled surface and not deformable at finger pressure (as A. quercuspomiformis comb. nov. and A. bassae n. sp.), but the size is smaller, around 20 mm in diameter.
Description. (Figs 6 A–6G).
Female. Body length: 3.8 mm. (N=1)
Colour. Head chestnut; antennae brown in basal half and ambarine distally; mesosoma chestnut to brown; legs brown, ambarine distally, coxae chestnut to brown, femora and tibiae light brown, except ambarine tarsi; metasoma ambarine.
Head (Figs 6 B–6D) trapezoidal in anterior view, 2.6x as broad as long from above, 1.4x as broad as high in anterior view and slightly narrower than mesosoma; frons with fine rugae, alutaceous interspaces, almost glabrous; lower face alutaceous, with more dense white setae. Gena dull rugose, slightly broadened behind eye, not visible behind eyes in anterior view, as broad as cross diameter of eye; malar space dull, delicately rugate; height of eye 1.7x as long as length of malar space. POL 0.8–0.9x as long as OOL; diameter of lateral ocellus equal to LOL; ocelli ovate. Transfacial distance 1.4x as broad as height of eye; diameter of antennal torulus subequal to distance between toruli, distance between torulus and inner margin of eye 1.7x as long as diameter of torulus. Clypeus dull smooth, ventrally projected, without median incision; anterior tentorial pits deep, epistomal sulcus conspicuous, clypeopleurostomal line distinct. Frons, vertex, interocellar area and occiput uniformly rugose with alutaceous interspaces. Occiput without dorsal carina. Labial palpus 3-segmented, maxillary palpus 5-segmented.
Antenna (Fig. 6G) with 11 flagellomeres; slightly longer than head+mesosoma; scape 1.8x as long as pedicel; pedicel subglobose, slightly longer than broad; F1 subequal to scape+pedicel and 1.3x as long as F2; F2 as long as F3; F3 nearly equal in length to F4, subsequent flagellomeres shorter, F11 partially divided, 1.8x as long as F10; placodeal sensilla visible on F5–F11, absent on F1–F4.
Mesosoma (Figs 6 D–6E) only slightly longer than high. Pronotum smooth dorsally, with numerous faint irregular rugae laterally. Mesoscutum round, uniformly rugose with alutaceous interspaces, rugose sculpture fainter and dull smooth interspaces on convergent point of median sulcus and notauli on posterior part; 0.8x as long as broad in dorsal view (largest width measured across mesoscutum on the level of tegulae base). Notauli incomplete, distinct under rugose sculpture on posterior half; notaular furrow faintly rugose with smooth interspaces; anterior parallel lines extending to almost half length of mesoscutum, slightly elevated, mesoscutum impressed along both sides of lines; parapsidal lines distinct, originating from posterior margin and extending to nearly half length of mesoscutum; median mesoscutal sulcus present, shiny smooth furrow; parascutal carina short, extending to level of tegula. Mesoscutellum 0.5x as long as mesoscutum, coarsely rugose with alutaceous interspaces, quadrangular, as broad as long, slightly overhanging metanotum, emarginate laterally; scutellar foveae quadrangular, shallow, faint median carina dividing the base of mesoscutellum into two halves, smooth foveae with faint transversal carinae connected to median carina, lateral sides of foveae with strong narrow carinae, separating them from dorsoaxillar area, posteriorly limited by rugate sculpture. Mesoscutellum with posteromedian depression emarginate by strong carinae. Mesopleuron uniformly rugose with alutaceous interspaces and sparsely pubescent, some rugae orientated into transverse faint subparallel striae. Mesopleural triangle rugose; dorsoaxillar area with faint rugae; lateral axillar area and axillula rugate, with few short, white setae; subaxilular bar smooth, shining, with parallel sides, its height less than height of metanotal trough, most posterior part extending to half height of mesoscutellum; postalar process long, with parallel striae; metapleural sulcus hidden under dull rugose sculpture. Metascutellum uniformly coriaceous, metanotal trough coriaceous, with dense white setae; ventral impressed area smooth, slightly shorter than height of metascutellum; central propodeal area faintly rugate, dull; lateral propodeal carinae high, subparallel, slightly curved outwards medially; lateral propodeal area with irregular strong wrinkles and dense white setae; nucha short, with irregular wrinkles around.
Legs with sparse short white setae; tarsal claws with basal lobe.
Forewing longer than body, mostly hyaline, with short dense cilia on margin, with dark stripe on basal part of radial cell, veins dark brown; radial cell narrow, long, opened on margin, 4.0x as long as broad; R1 and Rs nearly reaching wing margin; areolet infuscate, small, almost invisible, internal space round, closed; Rs+M reaching basalis at its half height.
Metasoma (Fig. 6F) as long as head+mesosoma, 1.2x as long as high in lateral view; 2nd metasomal tergum occupy nearly 2/3 of metasoma length, smooth, shining, with short sparse setae dorsolaterally and with larger patch of dense setae ventrolaterally; posterior third conspicuously finely punctate dorsally and laterally, posterior margin with a narrow smooth band, without punctures; all subsequent terga dorsally and laterally uniformly and entirely micropunctate, with a narrow smooth band posteriorly on each tergum. Ventral spine of hypopygium robust, short, needle-like, prominent part 5.0x as long as broad, with two rows of white setae each side, extending beyond apex of spine.
Gall (Fig. 16J). A relatively small, subglobose bud gall. The body of the gall reaches its greatest diameter near the middle, up to 20 mm in diameter. The gall is thick-walled, with lignified parenchyma, light brown when mature, with a smooth and naked surface; with spongious hard parenchyma internally; the hard-walled, ovate central larval chamber, with a mature length of 5.0– 6.5 mm.
Host. Quercus crassipes.
Biology. Only females are known. Mature galls were collected in December.
Distribution. Mexico: Ciudad de Mexico.
Remarks. This species was collected by Kinsey in 1932 and it was never described. Deposited in the Kinsey collection at the American Museum of Natural History (AMNH) as an ‘unidentified Amphibolips ’. Characters are clearly differing from any other Amphibolips species (see diagnosis).
