Trjapitziniola vanharteni n. sp. Buffington & van Noort

(Fig. 11)

Description. FEMALE. Head. Shiny, shagreened around ocelli and on vertex (Fig. 11 F); frons shagreened (Fig. 11 F), cheeks smooth; setae present only on frons and occiput. Antenna entirely dark brown/black; scape 2x length of radicle, short appressed setae present on all 11 flagellomeres, filiform, last pair nearly fused.

Mesosoma. Entire pronotum striate, shiny, with few sparse, long setae (Fig. 11 C); pronotal carina present dorsally, indistinct ventrally. Mesopleuron entirely striate; dorsal and ventral margins of mesopleural triangle clearly visible, glabrous anteriorly, weakly setose towards midpit (Fig. 11 C). Mesoscutum entirely shiny (lacking microsculpture) with several scattered setae present over entire surface; notaulices complete, originating at anterior end of parascutal impression; area between posterior junction of notaulices delineated by elongate impression (Fig. 11 D). Disk of scutellum anteriorly smooth, posteriorly strongly rugulose; disk distinctly angled midway, declined; declined area flat (Figs 11 B and 11C). Posterior margin of disk strongly rugose, bordered by raised carina (Fig. 11 B).

Metapleural-propodeal complex. Metapleuron glabrous except for sparse setae within the antero-ventral cavity (Fig. 11 C), entirely rugose. Propodeum crenulate, long setae present (Figs 11 C and 11D); area between propodeal carinae strongly carinate, glabrous. Nucha crenulate, not striate, protruding posteriorly.

Metasoma. Petiole striate without visible setae; petiole obscured anteriorly by syntergum. Syntergum smooth and shiny, entirely glabrous (Fig. 10 A). Entire metasoma, in lateral view, about as long as deep.

Wings. Pseudostigma weakly sclerotised, marginal cell clearly visible (Fig. 11 E).

Legs. Coxae and femora setose, light brown to orange, non metallic; remaining portion of legs orange, non metallic; legs evenly covered with long, non appressed setae entirely to claws (Fig. 11 A).

MALE. Unknown.

Diagnosis. Separated from T. popovi by having the scape 2x length of the radicle (1.25x length of radicle in T. vanharteni), posterior portion of the mesopleuron entirely striate (posteriorly smooth in T. popovi), having the ventral portion of the metapleuron smooth (crenulate in T. popovi) and having the ventro-posterior aspects of the propodeum setose (glabrous in T. popovi).

Etymology. Named for the collector, Anthony van Harten.

Distribution. Southwestern Asia: United Emirates Republic (Fig. 12).

Material examined. Holotype: UNITED EMIRATES REPUBLIC: Wadi Maidaq, 25.18N 56.07E, 29.III–10.IV.2006, in white & yellow water traps, A. van Harten, coll. [first label], USNM type [second label]. The holotype is a female mounted on a black card point; the right fore and hind wings are mounted on a white card below the black point. The holotype is in good condition. Deposited in USNM.

Additional material. None.
