Mongoloraphidia (Mongoloraphidia) kaszabi (H. Aspöck & U. Aspöck, 1967)

( Figs 8–12 )

Agulla kaszabi H. Aspöck & U. Aspöck, 1967: 26 . Type locality: Mongolia ( Mt. Altai ).

Raphidia (Mongoloraphidia) kaszabi H. Aspöck & U. Aspöck, 1968: 115 .

Mongoloraphidia (Mongoloraphidia) kaszabi H. Aspöck & U. Aspöck, 1985: 39 .

Diagnosis. This species is characterized by the male gonocoxite 9 with a long posteroventral and digitiform projection, which is distinctly curved dorsad, and the gonapophyses 9 (hypovalva) present as a long tongue-shaped sclerite, which is flat, straightly directed posteriad, anteriorly elevated ventrad in lateral view, and anterolaterally produced into a pair of short, acutely tapering projections.

Supplementary description of the specimen from Xinjiang. Male. Body length 9.3 mm; forewing length 9.2 mm, hind wing length 7.5 mm.

Head ovoid, blackish brown with clypeus brown. Compound eyes grayish black. Antennae blackish brown. Mouthparts brown.

Pronotum long, slender, blackish brown, posterior half with three yellowish brown stripes. Legs yellowish brown with blackish setae. Wings hyaline; pterostigma yellowish brown throughout; veins brown, but proximal half of C, R and A veins on forewings and bases of most longitudinal veins on hind wings yellow; anterior branch of RP in both fore- and hind wing with one simple and one bifurcate or trifurcate branch.

Abdomen black; each pregenital segment with a pair of yellowish vittae laterally, a triangular yellowish marking medially on tergum and a yellowish transverse stripe on posterior margin of sternum. Tergum 9 laterally markedly flexed, anterior margin moderately notched. Sternum 9 arcuate, rather narrow, and posteromedially prominent. Gonocoxite 9 ( Fig. 9 ) posteroventrally produced into a long digitiform projection, which is distally curved dorsad. Gonostylus 9 ( Figs 9, 10, 12 ) short, unguiform, strongly curved. Gonapophyses 9 (hypovalva) ( Fig. 12 ) long, straightly directed posteriad and exceeding apex of ectoproct, flatly tongue-shaped, largely paired but distally fused, anteriorly elevated ventrad in lateral view, anterolaterally with a pair of short, acutely tapering projections, laterally with numerous small teeth. Fused gonocoxites 11 (gonarcus) ( Figs 9–10 ) small, paired, strongly sclerotized. Endophallus ( Figs 9–10 ) broad.

Material examined. 1♂ [preserved in alcohol], CHINA: Xinjiang, Buerjin County, Kanas [布尔津县, 喀ṷ ª], 86°59′37.85″E, 48°41′4.62″N, 1470.8 m, 2017.VII.16, Jinlong Ren ( CAU) .

Distribution. China (Xinjiang), Mongolia (Hovd), Russia (Gorno-Altaysk).

Remarks. This species was originally described by H. Aspöck & U. Aspöck (1967) based on a single male specimen from Mt. Altai of Mongolia. Here Mongoloraphidia (M.) kaszabi is recorded from China for the first time based on the specimen from Xinjiang. The identification of this additional male specimen as M. (M.) kaszabi can be justified based on its male genital characters that are nearly identical to that of the holotype of this species (see H. Aspöck & U. Aspöck 1967: fig. 1). However, there is another species, namely Mongoloraphidia sajanica H. Aspöck, U. Aspöck & Martynova, 1968 , which is morphologically very similar to M. (M.) kaszabi and has geographically close distribution with the latter species. At present, it is not practical to clearly distinguish them as two independent species, and further investigation based on more specimens and molecular data is necessary to confirm if both are synonyms.
