The New World Belonopterygini (Neuroptera: Chrysopidae): descriptions of a new genus and species from the West Indies and comparisons among the genera Author Tauber, Catherine A. text Zootaxa 2021 2021-05-26 4975 3 509 543 journal article 6141 10.11646/zootaxa.4975.3.4 b58a1513-492f-45c0-bc72-21ae072fe689 1175-5326 4808947 8FF26470-F7DE-4C0C-9AA7-92CA479A6F96 Nacarina ( Brooks & Barnard 1990: 175–177 , Figs 179–186; Freitas & Penny 2001: 252–256 , Figs 1–7 ; Penny 2002: 206–208, Figs 132–140; Breitkreuz 2018: 286–290 ). Size: Body usually large and stout, but some species from Brazil relatively small and delicate; wing length 16–31 mm ; males smaller than females. Coloration: Yellow to cream, with or without markings on thorax, abdomen, or legs; antennal flagellum often dark basally. Wings: Not narrowed, with rounded tips; ratio of forewing length to width = 2.8–3.4: 1, without splayed crossveins; forewing and hindwing without markings, veins mostly pale. Tarsal claws: Basal dilation absent or small. Abdomen: Setae numerous, short, stout. Male: Dorsal apodeme of T9+e with basal section extending anteroventrally from behind callus cerci to or almost to end of T9+e (See Freitas & Penny 2001 : Figs 4D , 5D , 7A ); S8+9 fused with prominent suture or no suture; microtholi present or absent; gonarcal complex usually broad, with mediuncus having lateral arms; parameres rarely absent, with two arms fused. Female: No report of mesal suture dividing abdominal tergites; spermatheca with deep or shallow invagination; praegenitale present or absent; elongate, slender bursal ducts [shown for two species in Freitas & Penny 2001 : N. lavrasana Freitas & Penny and N. panchlora (Gerstaecker) ]. [Note: Figs 1 and 10 in Freitas & Penny are switched—the images on Fig. 10 should have the caption and placement of Fig. 1 , N. panchlora ; vice versa for the images on Fig. 1 —they belong with the caption of Fig. 10 , Ceraeochrysa cincta (Schneider) ]. In summary, Nacarina species (and the sexes) are variable in size, body form, and many genital traits (see Table 1 ). The claim that parameres are absent from Nacarina ( Brooks & Barnard 1990: 177 ) appears to have been premature. Apparently, they are present and associated with the gonosaccus in many species ( Freitas & Penny 2001 ), but the structure of the parameres has not been well defined or illustrated. Indeed, it is safe to say that this relatively large genus is in great need of morphologically based revisionary work.
