Hollowayosia cardamoma sp. n. https://zoobank.org/ urn:lsid:zoobank.org:act: 994C589B-9A20-4CB2-8422-DFFAF476A669 (Figs 61, 62, 117, 148) Type material. Holotype (Figs 61, 117): male, “SE Thailand | Prov. Chanthaburi, 150 m, | 33 km N Chanthaburi | 12°48,17'N, 102°17,53'E, | ♀ 30. X. 2010 ex L.[arva] K. Černý ” / “Slide | AV8225 ♂ | A. Volynkin ” (MWM / ZSM, ex CKC). Paratypes. THAILAND: 1 male, 2 females, same data as in holotype but not reared from larva, gen. slide Nos.: AV8226 ♀, AV9238 ♂, AV9239 ♀ (CKC). Diagnosis. The forewing length is 14.5–15.5 mm in males and 18.5–19.0 mm in females. Hollowayosia cardamoma sp. n. (Figs 61, 62) differs externally from H. longpala (Figs 59, 60) in the longer forewing. Additionally, the male hindwing of the new species is paler than in the similar congener. The male genital capsule of H. cardamoma sp. n. (Fig. 117) can be easily distinguished from H. longpala (Fig. 116) by the more asymmetrical valvae (the right one is markedly broader), the narrower and apically pointed dorsal-distal section of the valva (it is apically tapered in the congener), and the longer and straighter distal saccular process with a more elongate tip. Additionally, the uncus of the new species is slightly shorter and narrower, and the vinculum is somewhat shorter than the corresponding structures in H. longpala. The phallus of H. cardamoma sp. n. is shorter and distally broader than in H. longpala, medially downcurved (it is straight in H. longpala), and bears a very short and broad, triangular carinal process, which is narrow and claw-shaped in the similar congener. The vesica of H. cardamoma sp. n. differs from H. longpala in the broader main chamber and the markedly longer, proximally broader and granulose dorsal diverticulum, which is membranous and bearing a cluster of robust spines apically in H. longpala. Additionally, the distal diverticulum of the new species is longer, has a broader area of graniculi, and is directed ventrally (whereas it is medially membranous and distally directed in H. longpala), and the lateral diverticula are larger than in the similar congener. In the female genitalia, H. cardamoma sp. n. (Fig. 148) is distinguished from H. longpala (Fig. 147) by the posteriorly broader and more asymmetrical antrum having two broad and irregular sclerotised plates (vs. one narrow and symmetrical medial plate in H. longpala), the shorter and markedly narrower ductus bursae, the posteriorly narrower and more weakly gelatinous posterior section of the corpus bursae, the anterior section of the corpus bursae bearing two rounded and equally small signa (vs. a small rounded and a larger elliptical ones in H. longpala), and the larger and basally broader appendix bursae. Distribution. The new species is currently known from Southeast Thailand (Chanthaburi Province). The record of ‘ Cernyia longpala (Holloway, 2001) ’ from Cambodia (Bae et al. 2016) probably also belongs to H. cardamoma sp. n. but requires confirmation. Etymology. The specific epithet is derived from the Cardamom (Khelang) Mountains, where the new species is found. The name is a noun in the nominative singular in apposition.
