Genus Apertochrysa Tjeder, 1966 View in CoL View at ENA
Diagnosis
The genus Apertochrysa can be distinguished from other chrysopid genera in Pakistan by the following characters: antennal scape with lateral markings present (occasionally absent); forewing with elongated fifth and six cells beneath Rs ( Figs 3C–D View FIGURE 3 ); basal inner gradates in both fore- and hindwing not arise from pseudomedia (Psm); outer gradate always arise from pseudomedia ( Figs 17A–B View FIGURE 17 ); tibial spurs ratio in each legs are 0-1-1 ( Figs 3H–J View FIGURE 3 ); legs with basal dilation of pretarsal claw present (occasionally absent); sternum 8 and 9 fused, rounded posteriorly ( Fig. 19A View FIGURE 19 ); male genitalia with or without tignum, but the entoprocessus and gonapsis are always present ( Figs 19C, E View FIGURE 19 ); gonapsis with distinctive shapes (see Breitkreuz et al. 2021a), and a pair of lateral wings, which are connected to a single anteriorly-directed rod; female with variable shapes, wider than long ( Fig. 19M View FIGURE 19 ) or longer than wide ( Fig. 23F View FIGURE 23 ).
Notes
The genus Apertochrysa currently includes 183 species worldwide and is one of the largest genera within the family ( Duelli et al. 2017; Breitkreuz et al. 2021a). The taxonomic history of this genus is presented by Dong et al. (2004), Duelli et al. (2017), and Breitkreuz et al. (2021a). Here we record eight species of Apertochrysa from Pakistan. Among them, five species could not be identified to species, and the other two species are newly transferred to this genus. Among the undetermined female Apertochrysa species, A. sp. 2 has the subgenitale wider than long, while it is longer than wide in A. sp. 4 and A. sp. 5. All of these species, which are solely described based on females, require additional specimens to investigate the male genitalia; however, at present, these species differ in body coloration and shape of pretarsal claws. The known ranges of all these species is in in the northern portion of the country.
