Trjapitziniola popovi (Kovalov 1995:140) . Type species by original designation and monotypy.

Redescription. non-type MALE, Head. Shiny without microsculpture around ocelli and on vertex ( Fig. 10 View FIGURE 10 C); frons shagreened ( Fig. 10 View FIGURE 10 E), cheeks smooth; setae present only on frons and occiput. Antenna entirely dark brown/black; scape 1.25x length of radicle, short appressed setae present on all 16 flagellomeres, filiform. Mesosoma. Upper part of lateral aspect of pronotum entirely smooth to weakly shagreened, shiny, with few sparse, long setae ( Fig. 10 View FIGURE 10 B); pronotal carina present, extending ventrally from anterior half of pronotal plate. Mesopleuron with distinct striations anteriorly, smooth posteriorly; dorsal and ventral margins of mesopleural triangle clearly visible, glabrous anteriorly, weakly setose towards midpit ( Fig. 10 View FIGURE 10 B). 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. 10 View FIGURE 10 C). Disk of scutellum anteriorly smooth, posteriorly strongly rugulose, distinctly angled midway, declined posteriorly; declined area flat ( Figs 10 View FIGURE 10 B and 10D). Posterior margin of disk strongly rugose, bordered by raised carina.

Metapleural-propodeal complex. Metapleuron glabrous except for sparse setae within the antero-ventral cavity ( Fig. 10 View FIGURE 10 B), strongly rugose, slightly smoother ventrally. Propodeum crenulate, sparsely setose to entirely glabrous; 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 View FIGURE 10 A). Entire metasoma, in lateral view, about as long as deep.

Wings. Pseudostigma weakly sclerotised, marginal cell clearly visible ( Fig. 10 View FIGURE 10 D).

Legs. Coxae and femora setose, dark brown/black, non metallic; remaining portion of legs brown except for orange, non metallic joints; legs evenly covered with long, non appressed setae entirely to claws ( Fig. 10 View FIGURE 10 A).

FEMALE. Data taken from Kovalev (1995). As in male except antenna 12 segmented, clavate; relative length of scape to radicle unpublished.

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

Distribution. Southwestern Asia: Turkmenistan, Armenia. ( Fig. 12 View FIGURE 12 )

Material examined. Non-type: ARMENIA: Sisian, 23.VI.1957, V. Tryapitsyn [collector] (label in Russian; locality data taken from Kovalev (1995)) (1 male). Deposited in ZMAS.

Note: The holotype specimen of T. popovi is in very poor condition. It was the opinion of O. Kovalev (pers. comm.) that the specimen best stay in St. Petersburg and not travel for further examination. Hence, the redescription here is based on conspecific material included in the original description of T. popovi .
