Diachasmimorpha norrbomi Wharton, 2012
Size variation in this species is similar to that exhibited by D. martinalujai, with males dominating the small end of the range.
Mesosoma 1.35-1.45 x longer than high; 1.85-1.95 x longer than wide; 1.35-1.40 x higher than wide. Pronope deep, large, interrupting posterior crenulate groove middorsally; crenulae extending along dorsal 0.2 of pronotum laterally within narrow, shallow groove; groove not margined anteriorly by carina; anterior margin of pronotum laterally sinuate (Fig. 5), not abruptly excavated. Notauli (Figs 4, 5) deep anteriorly, gradually weakening posteriorly, extending posteriorly to level of tegula, not reaching long, narrow midpit, anterior end usually just short of and only rarely reaching anterior-lateral margin of scutum; mesoscutum usually without supra-marginal carina between base of notaulus and tegula, rarely with short, weak trace of a carina. Scuto-scutellar sulcus nearly rectangular, a little narrower medially; 4.2-4.8 x wider than midlength; crenulate-foveolate. Propodeum rugose, areola extending over posterior 0.8 but largely obscured by sculpture. Precoxal sulcus crenulate, widely separated from anterior margin of mesopleuron.
Wings (Fig. 6). Fore wing stigma short, broad, discrete distally, 3.15-3.30 x longer than wide; r1 arising from midlength of stigma; 1RS (excluding parastigma) 0.30-0.35 x length of 1M; m-cu postfurcal by 0.2-0.3 x length of m-cu; second submarginal cell distinctly converging distally; 2RS 1.0-1.2 x longer than 3RSa; 2CUa 1.6-1.8 x longer than 2cu-a; 1cu-a distad 1M by about 1.0 x its length.
Metasoma not distinctly petiolate; head 1.6-1.9 x wider than apex of T1. T1 0.95-1.05 x as long as apical width; strongly diverging apically, with apex 2.0-2.5 x wider than base; surface smooth to weakly strigose posterior-medially, almost completed smooth laterally; dorsal carinae weakly converging, widely separated at posterior margin, strongly elevated over anterior 0.5, gradually weakening posteriorly; lateral carina weaker, extending distinctly ventrad spiracle, rounded and barely distinguishable posteriorad spiracle; spiracle at midlength of T1; dorsope absent but lateral and dorsal carinae elevated at junction, giving appearance of a slight depression; laterope deep; S1 very short, extending posteriorad to level of dorsal tendon attachment. T2 unsculptured, with sharp lateral margins. Ovipositor sheath (Figs 1, 2, 7) 1.7-1.8 x longer than mesosoma, setal pattern about as in D. martinalujai, with slightly greater density basally.
Color (Figs 1-4). Very similar to D. hildagensis. Meso- and metasoma orange, except tegula black; head dorsally dark brown to black except for small orange spot on vertex adjacent eye, lower occiput mostly yellow-orange, similar in color to broad band extending through epistomal sulcus, clypeus, lower gena (often), and mandibles; clypeus usually with narrow, transverse brown band, mandible with apical teeth dark, rarely with entire mandible brownish; legs black except extreme base and most or all of dorsal side of hind coxa orange, joint between femora and trochantelli reddish orange.
Male as in female except head in dorsal view 1.3-1.4 x broader than mesoscutum, 1.70-1.75 x broader than face; eye slightly smaller, in dorsal view eye 1.45-1.60 x longer than temple, in lateral view 1.9-2.4 x longer than temple; antenna with 41-43 flagellomeres, first flagellomere 0.95-1.2 x longer than second. Mesosoma slightly narrower, 1.95-2.05 x longer than wide; 1.4-1.5 x higher than wide; scuto-scutellar sulcus somewhat more variable in size, 4.0-5.5 x wider than midlength. Fore wing stigma 3.1-3.4 x longer than wide. T1 slightly smaller, head 1.9-2.2 x wider than apex of T1, T1 1.75-1.90 x wider at apex than at base.
Body length 3.3-4.3 mm, fore wing length 3.5-4.1 mm, mesosoma length 1.15-1.65 mm.
Paratypes: 27 females, 20 males, same data as holotype (TAMU, UNAM, USNM).
Other specimens examined (not paratypes): 1 female, 1 male, Mexico, D.F., Delegacion Tlapan, Fracc. Tlapuente, 19.ix.2003, M. Aluja #50, reared from fruit of Granadilla (TAMU).
In the original description of this species (Wharton et al. 2012), the type locality was incorrectly stated as being in the state of Mexico. The type locality is actually in the state of Morelos. The first line on the top label of the holotype (as given verbatim in the next section) and paratypes is therefore incorrect.
Two additional specimens that fit within the morphological limits of this species were reared from an unknown tephritid infesting Passiflora ligularis Juss.
