Palaeoides Belokobylskij subgen. nov.

Type species.

Centistoides (Palaeoides) magnioculus sp. nov., by present designation.

Etymology.

Named after “Palaeo” (Greek for “ancient”) and part of the generic name Centistoides from the tribe Centistini .

Description.

Ocelli less distinctly enlarged (Fig. 1D, E View Figure 1 ). Palpi longer, maxillary palpus more than 3-segmented, perhaps with 5 segments; labial palpus at least 2-segmented (Fig. 1D View Figure 1 ). Prescutellar depression with five carinae (Fig. 1D View Figure 1 ). Precoxal sulcus present, but very shallow (Figs 1A View Figure 1 , 2C View Figure 2 ). In fore wing, discoidal (discal) cell petiolate anteriorly, petiole (1-SR) medium length (Fig. 2A, B View Figure 2 ). Mediocubital vein (M+CUl) entirely distinctly sclerotised and pigmented (Fig. 2A, B View Figure 2 ). Fore femur not more robust than hind femur (Fig. 2C View Figure 2 ). Tarsal claws weakly curved apically (Figs 1A View Figure 1 , 2A, C View Figure 2 ). Second metasomal suture present but fine (Fig. 1F View Figure 1 ). Ovipositor sheath weakly narrowed apically (Fig. 1F View Figure 1 ).

Diagnosis.

The genus Centistoides (as well as Asiacentistes ) characterised by the fore wing mediocubital vein (M+CU1) distinctly sclerotised and pigmented, when such a vein in most Centistini genera is clearly desclerotised and transparent (spectral). Both known Centistoides species, C. doesburgi van Achterberg, 1992 and C. ophthalmicus (Granger, 1949), together with the genus Asiacentistes , have a sessile or subsessile discoidal (discal) cell in the fore wing ( van Achterberg 1992; Belokobylskij 1995, 2018), while in the new subgenus, Centistoides Palaeoides subgen. nov., the discoidal (discal) cell of the fore wing is petiolate.
