( Figs 7–12 View Figures 1–12 , 19–24 View Figures 13–19 View Figures 20–22 View Figures 23–24 )
Type-species: Chryseacampa evani sp. n., here designated.
Description. Male ( Figs 7–8, 11–12 View Figures 1–12 ). Forewing. Forewing length: 18–20 mm; wingspan: 38–40 mm. Short, somewhat trapezoid. External margin slightly crenate. Background color creamy or reddish brown. Pattern consists of more or less pronounced dark crenate ante- and postmedial lines, pale c-shaped discal mark, and fragmented external line. Fringe speckled, colored like background and pattern color. Hindwing. Ovate with slightly crenate external margin. Background color creamy or reddish brown. Pattern absent, only darker anal field or darker anal angle may be pronounced. Fringe speckled, colored like background and pattern color. Genitalia ( Figs 20–22 View Figures 20–22 ). Tegumen dorsolaterally bears a pair of fused basally socii. Socii enlarged, sclerotized, somewhat triangle, ventrally covered with setae. Cucullus long, claw-shaped, sparsely covered with setae. Sacculus tiny, knob-like, densely covered with setae. Vinculum medially thin, fused with ring-like juxta surrounding aedeagus; vinculum has a pair of laterodistal outgrowths. Aedeagus claw-like, dorsobasally has apodeme, ventroapically bears spur. Vesica narrow, bears cornuti. The eight sternite somewhat trapezoid, lateroproximally has short apodemes, distal margin more sclerotized. Female ( Fig. 9 View Figures 1–12 ). Externally similar to male. Forewing length: 31 mm; wingspan: 60 mm. Genitalia ( Fig. 19 View Figures 13–19 ) Papillae anales oval, densely covered with setae. Posterior apophyses one fourth longer than the anterior ones. Sterigma highly sclerotized, somewhat trapezoid, medially membranous with semi-round ostium. Ductus bursae short. Corpus bursae ovoid, bears small round signum.
Diagnosis. The following three genera are morphologically close to Chryseacampa gen. n. and, thus, compared with its members: 1) Pachymetana , 2) Mallocampa , and 3) Dollmania .
1) The genus Pachymetana contains 10 species (type species Pachymetana custodita Strand, 1912 ; see De Prins & De Prins, 2011 –2021). Male adults of Chryseacampa gen. n. have shorter forewings with c-shaped discal mark ( Figs 7–8, 10–12 View Figures 1–12 ), while the ones of Pachymetana have elongated forewings with white discal dot ( Fig. 2 View Figures 1–12 ). Female adult of Chryseacampa gen. n. has evenly colored hindwing ( Fig. 9 View Figures 1–12 ), while the one of Pachymetana has contrasting basal field on hindwings ( Fig. 1 View Figures 1–12 ). In male genitalia of Chryseacampa gen. n. socii expanded and basally grown together; cucullus sharply bent; sacculus very small; vinculum medially narrow and fused with ring-like juxta, laterodistally has outgrowths; aedeagus S- or C-shaped with dorsobasal apodeme and apical dent; vesica narrow with one dorsal cluster of cornuti; the eight sternite elongated distally with more sclerotized distal margin ( Figs 20–22 View Figures 20–22 ); while in Pachymetana socii small and separate; cucullus around 90 degrees bent; sacculus medium-sized, somewhat triangle; vinculum does not fuse with juxta, laterodistally slightly wider; aedeagus C-shaped without apodeme and apical dent; vesica basally large, has two dorsal ridges covered with cornuti; the eighth sternite somewhat trapezoid with mediodistal concavity, laterobasal narrow apodemes ( Fig. 13 View Figures 13–19 ). In female genitalia of Chryseacampa gen. n. sterigma membranous medially, bursa has small round signum ( Fig. 19 View Figures 13–19 ), while in Pachymetana sterigma has no medial membrane, bursa has no signum ( Fig. 16 View Figures 13–19 ).
2) The genus Mallocampa contains 10 species (type species Mallocampa audea (Druce, 1888) ; see Prozorov, Zolotuhin, 2013 a, 2013b; De Prins & De Prins, 2011 –2021). Adults of Chryseacampa gen. n. have c-shaped discal mark ( Figs 7–12 View Figures 1–12 ), while adults of Mallocampa have discal dot of short stroke ( Fig. 3– 4 View Figures 1–12 ). In male genitalia of Chryseacampa gen. n. socii short; cucullus elongated, claw-shaped with one apex; vinculum has laterodistal outgrowths; aedeagus elongated, S- or C-shaped; vesica elongated with dorsal cluster of cornuti; the eight sternite has no distal dents ( Figs 20–22 View Figures 20–22 ); while in Mallocampa socii very long; cucullus short, with three apices; vinculum has no laterodistal outgrowths; aedeagus short, claw-shaped; vesica tiny, without cornuti; the eighth sternite has pair of distal dents ( Fig. 14 View Figures 13–19 ). In female genitalia of Chryseacampa gen. n. sterigma somewhat trapezoid, membranous medially ( Fig. 19 View Figures 13–19 ), while in Mallocampa sterigma somewhat triangle with pin-like mediodistal extension ( Fig. 17 View Figures 13–19 ).
3) The genus Dollmania contains 6 species (type species Dollmania plintochroa Tams, 1930 , junior synonym of Dollmania cuprea ( Distant, 1897)) . We showed that male genitalia of Dollmania spp. have weak intraspecific differences (see Prozorov et al., 2023b, 2023c), so here for comparison we take genitalia of Dollmania ivoriensis Prozorov et al., 2023 . Adults of Chryseacampa gen. n. have shorter forewings with doubled medial lines and nearly white discal mark ( Figs 7–12 View Figures 1–12 ), while adults of Dollmania have elongated wings with multiple medial lines and darker diskal mark ( Fig. 3–4 View Figures 1–12 ). In male genitalia of Chryseacampa gen. n. socii fused basally, have two apices; cucullus C-shaped; sacculus very small; aedeagus S- or C-shaped; juxta surrounds aedeagus; vesica elongated; the eight sternite has no distal dents ( Figs 20–22 View Figures 20–22 ); while in Dollmania socii not fused basally, have one apex; cucullus slightly C-shaped; sacculus medium-sized; aedeagus C-shaped; juxta stem-like, fused with aedeagus basally; vesica small; the eighth sternite has distal dents ( Fig. 14 View Figures 13–19 ). In female genitalia of Chryseacampa gen. n. sterigma somewhat trapezoid, membranous medially ( Fig. 19 View Figures 13–19 ), while in Dollmania sterigma somewhat oval with a slit-like opening ( Fig. 18 View Figures 13–19 ).
DNA comparison ( Fig. 23 View Figures 23–24 ). One species of the genus has been sequenced – Chryseacampa evani sp. n. The p -distance between Chryseacampa evani sp. n. and P. custodita is 6.4–7%; between Chryseacampa evani sp. n. and M. audea is 7.9–8.1%; between Chryseacampa evani sp. n. and D. cuprea is 5.6–6.8%.
Included species: Chryseacampa evani sp. n. and Chryseacampa ralphyi sp. n.
Etymology. The genus name consists of the Latin “chryseum” for “golden,” and “campa” from Lasiocampa Schrank, 1802 ; Mallocampa and others.
