Type species.

Paralanceis chotardi sp. nov.

Etymology.

The genus name is a combination of Para - and - lanceis, contraction of Lancepyris , for the similarities between the latter and the new proposed genus. Gender masculine.

Diagnosis.

Female. Body stout (Fig. 5A View Figure 5 ); head ovoid; compound eye slightly longer than high, located anteriorly on head; clypeus with median lobe triangular, lateral lobe shorter; toruli separated by flat surface; antenna short; mandible with three teeth (Fig. 5B-D View Figure 5 ); propleuron elongate and visible dorsally; pronotum with lateral margin straight; metanotum long; metapectal-propodeal complex smooth, without projection (Fig. 5A View Figure 5 ); fore wing with [1M] cell elongate, fully enclosed by tubular veins; pterostigma elongate; 2r-rs&Rs arising from distal half of pterostigma; 2r-rs&Rs fully tubular; R1 tubular, closing [2R1] cell; [2R1] cell lanceolate (Fig. 5E, F View Figure 5 ).

Systematic remarks.

Following the key to the genera of Lancepyrinae of Jouault et al. (2021), our specimen keys to Lancepyris due to the fore wing with Rs+M vein tubular and the [2R1] cell closed. It differs from this genus, however, by the head less elongate, the eyes more rounded, the space between the toruli flat, and the fore wing with [1M] cell fully enclosed by tubular veins. It also differs from Azepyris gen. nov. by the vein Rs+M tubular, the cu-a vein aligned with 1M, the [1M] cell enclosed by tubular veins and the absence of lateral dentiform projections on the posterior corners of the metapectal-propodeal complex; from Gwesped by the R1 vein long, distally meeting 2r-rs&Rs, the [1M] cell enclosed by tubular veins, the antennae with 11 flagellomeres and the absence of lateral dentiform projections on the posterior corners of the metapectal-propodeal complex. Compared to all the lancepyrine genera but Lancepyris , it is particular for possessing the [2R1] cell closed. Therefore, we propose the new genus Paralanceis gen. nov. to accommodate this morphotype.
