Entedonomphale boccaccioi sp. n.

Figs 10–14

Etymology: This species is named after Giovanni Boccaccio.

Diagnosis: This species is defined based on the unique combination of the following morphological features: male antenna with a 2-segmented funicle and a solid clava (the only species of Entedonomphale known to have an undivided clava of the male antenna); female antenna with a slender scape and relatively small funicle segments, their combined length much less than length of clava (F1 without sensilla); both sexes: forewing disc hyaline, with setae very short and inconspicuous, marginal setae short; apex of hind wing broadly rounded. Morphologically, the female of E. boccaccioi sp. n. is somewhat similar to the much darker (black) female of another North American species, E. nubilipennis , which has a narrower forewing (about 3.0 x as long as wide) with a medial cloud on the disc and relatively longer marginal setae.

Description: Female (holotype and paratype). Body and appendages brown to dark brown except F1 light brown.

Head normal, not compressed dorso-ventrally; vertexal suture faint but distinct. Antenna ( Fig. 10 ) with scape slender, about 3.0 x as long as wide; F1 a little longer than wide and without sensilla, F2 a little wider than long and with 1 sensillum; clava much longer than funicle, about 2.3 x as long as wide, with numerous sensilla.

Mesosoma shorter than metasoma, almost smooth. Midlobe of mesoscutum with 2 pairs of setae; anterior margin of scutellum almost straight. Forewing ( Fig. 11 ) about 2.7 x as long as wide; longest marginal setae about 0.28 x maximal forewing width; disc hyaline, more or less evenly setose in apical half of forewing (setae very short, inconspicuous). Hind wing ( Fig. 12 ) about 6 x as long as wide, with broadly rounded apex; disc relatively wide, with several rows of setae, more or less evenly covered with short, inconspicuous setae; longest marginal setae about 3/4 maximal width of hind wing. Coxae lightly sculptured.

Figs 15, 16. Entedonomphale bicolorata , female (paralectotype of Thripoctenoides gaussi ): (15) antenna, (16) forewing. Scale lines = 0.1 mm.

Petiole conspicuous, longer than wide (length/width ratio about 1.5:1). Ovipositor relatively short, occupying a little less than 1/2 length of gaster, not exserted; ovipositor length/metatibia length ratio about 1.3:1.

Measurements (n=1, holotype). Body: 1661. Antenna: scape: 203; pedicel: 64; F1: 38; F2: 36; clava: 139. Forewing: 923/339; longest marginal seta: 97. Hind wing: 824/136; longest marginal seta: 96. Ovipositor: 358.

Male (paratype). Body length 1292. Generally similar to female except for colouration of antenna (all segments brown) and normal sexually dimorphic features such as antenna and genitalia. Vertexal suture indistinct. Antenna ( Fig. 13 ) with a 2-segmented funicle and a solid clava; flagellar segments with numerous long setae. Petiole a little shorter than in female. Genitalia as in Fig. 14 .
