Panteliella rugosa Nastasi & Deans 2024, sp. nov.

Panteliella rugosa Nastasi sp. nov. urn:lsid:zoobank.org:act: BFD917CC-CDC3-4755-B88D-07A212879EDE (Figs. 9–14) Material examined. Holotype female: INHS Insect Collection 288137. Kyrgyzstan: Osh Region, Ikazak, 2 km east of junction with Koksu River, 39°42′51″ N, 73°46″30″ E (approximately 39.714, 73.775 in decimal degrees). 3100m elevation. Collected 9 July 2000, by vacuum. Field code 00-092-08. C. H. Dietrich leg. Etymology. Named for the abundant rugose sculpture on the mesoscutum of this species. Noun in apposition. Description. Female (Fig. 9)–Body 1.5 mm in length. Coloration of head mostly orangish brown, with occiput dark brown; mesosoma more or less entirely black; metasoma dark reddish brown. Mandibles yellow. Antennae orangish brown, with scape and pedicel slightly darker than following antennomeres. Wing veins brown. Legs yellow except coxae and femora light brown proximally to yellow distally and apical tarsomeres light brown. Head (Fig. 10). In dorsal view 1.8× as wide as long; in anterior view subtrapezoidal and 1.2× as wide as tall. Sculpture excluding facial radiating striae entirely coriaceous. POL:LOL:OOL:DLO in holotype measuring 13:6:8:3. Toruli situated about mid-height of eyes. Malar space about 0.75× as long as compound eye in anterior view. Facial radiating striae incomplete, poorly impressed, apparent as weak striations emanating for a short distance from the clypeus. Clypeus large, broadly projecting ventrally over base of mandibles, and with clypeo-pleurostomal lines strongly divergent ventrally. Genae only slightly expanded posterior to eyes. Antennae (Fig. 9). With 13 antennomeres, about two thirds as long as body length. Conspicuous placodeal sensilla present on F2 and following flagellomeres. Pedicel shorter than F1. F1 2.3× as long as wide. F2 2.6× as long as wide; about 1.0× as long as F1. Apical flagellomere 3.7× as long as wide. Mesosoma (Figs. 11–13). In lateral view somewhat convex anteriorly but conspicuously angled in posterior three quarters. Pronotum mostly coriaceous, with some apparent rugose sculpture lateral to pronotal plate; with medial height about 0.3× height of lateral margin. Submedial pronotal pits transverse, deep, and clearly separated. Pronotal plate incomplete, with lateral sutures terminating only shortly before reaching mesoscutum. Mesopleuron almost entirely striate, with a very small ventral area of reticulate sculpture. Mesopleural triangle conspicuously impressed, densely setose throughout. Mesoscutum strongly reticulate with abundant transverse rugae, with only a few sparse, scattered setae. Notauli incomplete and inconspicuous; apparent only as short longitudinal rugae in posterior third of mesoscutum. Median mesoscutal impression inconspicuous. Mesoscutellar disc entirely rugose-reticulate, with conspicuous rugae anteriorly. Mesoscutellar foveae ovate; relatively short, about one quarter as long as mesoscutellar disc; posterior margins poorly defined but strongly divergent; without setae; rugose within margins; separated by a broad subtriangular area. Metapleural sulcus meeting mesopleuron in dorsal third. Metapleuron coriaceous to rugose, more or less moderately setose throughout. Propodeal carinae conspicuous, apparent as paired subparallel lateral carinae. Fore wing (Fig. 14). Hyaline and setose throughout. Marginal cell open, 3.4× as long as wide, with vein R1 indistinctly reaching fore wing margin. Areolet absent. Distal margin with conspicuous marginal setae. Metasoma (Fig. 9). Slightly longer than combined length of head and mesosoma. Second metasomal tergite with sparse micropunctation in posterior third. Third and following metasomal tergites with sparse micropunctation throughout. Male– Unknown. Remarks. We examined Panteliella fedtschenkoi and reviewed descriptions and redescriptions of its synonyms (Belizin 1959, Ionescu & Roman 1960, Quinlan 1968) and found that our P. rugosa is morphologically distinct from these species (Table 1). While the host of P. rugosa is not yet known, it is probably associated with Phlomoides tuberosa or a related species, as is the case for all taxa currently placed within Panteliella.
