Trimorus calligetus Kononova & Kozlov, 2001: 231 . Original description.

FEMALE (Holotype): Length= 0.95 mm.

Brown; maxillary palp, mandible, interantennal process, radicle, A1 proximally, A2, legs, including coxae, excluding apical brown tarsomeres yellow.

FCI =1.25; LCI =1.45; HW/IOS =1.57; head less than 1.5 times as wide as mesosoma (HW/TSL = 1.33); facial striae exceeding midlevel of eye, exceeding frontal patch; frontal patch distinct; frons setae sparse, thin; central keel complete, indistinct dorsally, obscured by frons sculpture; POL less than 1.5 times as long as OOL (POL/OOL =1.2); OOL more than 1.5 times as long as LOL (OOL/LOL =1.66); hyperoccipital carina absent; vertex entirely reticulate, vertex sculpture extending anteriorly to frons, merging posteriorly with genal patch; A1 less than 5.0 times as long as radicle (A1/r =4.25), shorter than clava (A1/cl =0.83).

Epomial carina absent, cervical pronotal area smooth, with sparse setae, setal bases pustulate; lateral pronotal area reticulate dorsally, with few crenulae above pronotal ventral projection; netrion sulcus complete; netrion sculpture not extending onto lateral pronotal area; pronotal suprahumeral and cervical sulci not foveolate; mesoscutum about 1.5 times as wide as long (TSL/ML =1.55); notaulus short, not exceeding transscutal line, distance between posterior end of notauli more than two times as long as distance between posterior end of notaulus and posterolateral edge of mesoscutum; mesoscutum entirely sculptured; mesoscutellum about 2 times as wide as long (SW/SL =1.94); scuto-scutellar sulcus almost as wide medially as laterally; mesoscutellum smooth, with sparse, long marginal setae, setal bases pustulate; posterior scutellar sulcus not extending onto axillula; sternaulus not separated from anterior row of foveae of mesopleural carina; sulcus along metapleural carina foveolate; metascutellum triangular, only base striated, with a triangular, semitransparent lamella apically; propodeal lateral carinae inverted V-shaped, shafts straight; propodeal lateral area and plical area with dense setae, marginal striation not extending medially; posterior propodeal projection indistinct; fore wing as wide as mesoscutum (TSL/WW =1.04); marginal vein more than 5 times as long as stigmal vein (m/st =5.62); hind wing about two times as wide as marginal ciliae length (HWW/ HWS =1.9).

T1 less than 1.5 times as wide as T1+T2 length (T1W/T1+T2L =1.48); T3 about 1.5 times as wide as long (T3W/T3L =1.57), about 1.2 times as wide as mesoscutum (T3W/TSL =1.22); costae on T3 exceeding 1/3 of tergum; lateral patch present; posterior patch of T3 reduced, nearly equal to width of 2–3 basal depressions; lateral and median patches on T4 present, separated.

Variability (n=5): Length= 0.78–0.95 mm (m=0.85, SD =0.08); FCI =1.21–1.25 (m=1.22, SD =0.02); LCI =1.45–1.54 (m=1.49, SD =0.04); HW/IOS =1.57–1.66 (m=1.63, SD =0.04); HW/TSL =1.33–1.36 (m=1.34, SD =0.01); POL/OOL =1.2–1.21 (m=1.20, SD =0.006); OOL/LOL =1.63–1.66 (m=1.65, SD =0.01); A1/r =4.16–4.28 (m=4.23, SD =0.06); A1/cl =0.83–0.85 (m=0.84, SD =0.01); TSL/ML =1.55–1.58 (m=1.56, SD =0.01); SW/SL =1.94–2.09 (m=2.03, SD =0.08); TSL/WW =1.04–1.13 (m=1.04, SD =0.05); m/st =5.33– 5.62 (m=5.48, SD =0.14); HWW/HWS =1.77–2.0 (m=1.89, SD =0.11); T1W/T1+T2L =1.36–1.48 (m=1.41, SD =0.05); T3W/T3L= 1.48–1.68 (m=1.57, SD =0.09); T3w/TSL=1.10–1.20 (m=1.17, SD =0.06)

MALE: Unknown.

Diagnosis. Most closely related to X. buccatus , differing in the more elongated metasoma, entirely sculptured frons, well developed fore and hind wings and less transverse mesoscutellum. Differs from X. cornutus in entirely sculptured frons and mesoscutum, less elongate metasoma and wider fore wing.
