Dasysapyga van Loon, 2024

Genus Dasysapyga van Loon , gen. nov.

Type species: Dasysapyga picta van Loon , sp. nov., by present designation.

Diagnosis. The unique hind wing venation separate Dasysapyga gen. nov. and the other Oriental genus Parasapyga from all other Sapyginae . Among Old World Sapyginae , the connection of the frontal shelf to the dorsal margin of the clypeus is also unique, however this condition is also seen in some New World Sapyginae such as Eusapyga Cresson, 1880 , Huarpea Pate, 1947 and Sapyga louisi Krombein, 1938 and the Old World species Polochridium spinosum Yue, Li & Xu, 2017 . In addition to characters listed in the key, Dasysapyga gen. nov. can be distinguished from Parasapyga by the following: frontal carina not distinctly developed above antennal sockets (frontal carina distinct above antennal sockets in Parasapyga ); median sector of mesoscutum-scutellar suture between scutellar axillae very short, clearly shorter than median scutellar length (as broad as long or broader than scutellar length in Parasapyga ); vein 2rs-m of fore wing apically separated by more than 4.0 AOD from wing margin (separated by approximately 3.0 AOD in Parasapyga ); lamella of fore tibial spur apically acute (lamella apically rounded in Parasapyga ); body bicoloured (body tricoloured in Parasapyga , with a bright red metasoma).

Description. Clypeus with median lobes rounded, dorsally directly connected to the frontal shelf of the frons ( Fig. 2B View FIGURE 2 ). Frontal carina distinct medially, not developed above antennal inserts ( Fig. 2B View FIGURE 2 ). Ocellar triangle compact, ocelli moderate-sized ( Fig. 3A View FIGURE 3 ). Vertex slightly raised behind lateral ocellus ( Fig. 2C View FIGURE 2 ). Malar space short, gena broad and strongly convex ventrally ( Fig. 2C View FIGURE 2 ). Occipital carina present laterally. Flagellomeres nodular, longer than broad and entirely clothed in dense sensilla ( Fig. 2A View FIGURE 2 ). Mesosoma compact ( Fig. 3A View FIGURE 3 ). Propodeum with distinct anterodorsal horizontal surface and posterior declivitous surface, rather sparsely punctate throughout, with shiny interstices; posterior declivity convex and laterally with a large polished area ( Figs 1B View FIGURE 1 , 3A,B View FIGURE 3 ). Second submarginal cell of forewing short and receiving first recurrent vein subbasally ( Fig. 4A View FIGURE 4 ). Third submarginal cell anteriorly narrower than posteriorly, vein 2r-m sinuous ( Fig. 4A View FIGURE 4 ). Hind wing vein r-m distinctly angled ( Fig. 4B View FIGURE 4 ). Foretibial spur bidentate, dorsal lamella not reaching apical tip of spur. Hindcoxa without dorsobasal carina; hindtarsus short, combined length of apical tarsomeres shorter than basitarsus ( Fig. 1A View FIGURE 1 ). Metasomal tergites coriaceous, without distinct punctures ( Fig. 3C View FIGURE 3 ); anterolateral spiracle of T1 not tuberculate. Pubescence short and generally dense, especially on metasoma and forecoxa; T6 with numerous bristly setae ( Figs 1A View FIGURE 1 , 3C View FIGURE 3 ).

Etymology. The generic name is derived from the ancient Greek prefix ‘ dasy -‘, meaning ‘hairy’, and the suffix taken from the generic name Sapyga Latreille, 1796 , and refers to the dense and shaggy pilosity of the body. The gender is feminine.

Distribution. Oriental: Southeast Asia (Borneo).
