Genus Macroilleis Miyatake

Macroilleis Miyatake, 1965: 71 .

Type species: Halyzia hauseri Mader, 1930 , by original designation.

Anchilleis Iablokoff-Khnzorian 1979: 63. Type species: Thea chapuisi Crotch, 1874 , by original designation. Synonymized by Kovář 2007: 72; Li et al. 2010: 16.

Diagnosis. Form elongate oval, dorsum convex and glabrous. Head with large eyes and comparatively narrow frons. Antenna with 11 antennomeres, long and slender, antennomeres 3–8 much longer than wide, 9–11 forming a loosely jointed, elongate club. Terminal maxillary palpomere transverse, but to a lesser degree than in Illeis . Abdominal postcoxal line incomplete, very short and apically barely recurved. Male genitalia with penis capsule prominent with an indistinct inner process, parameres characteristic with two lobes, the inner, subapical lobe shorter than the outer lobe, both covered with dense pubescence. Spermatheca strongly curved and C-shaped, with a well-differentiated ramus and nodulus, infundibulum distinct, tubular, enclosing the sperm duct.

Distribution. India, Nepal, Bhutan, Pakistan, Central and southern part of China, Vietnam, northeastern Borneo and Java ( Miyatake 1965; Poorani 2002; Li et al. 2010).

Affinities. Tomaszewska et al. (2021) included it in the Synonycha -group of genera and recovered the genera of the former tribe Halyziini including Psyllobora , Oxytella , Illeis , Vibidia , Macroilleis , and Halyzia as a major subclade in this group.

Included species. Li et al. (2010) revised this genus and included three species, of which only Macroilleis hauseri (Miyatake) is distributed in this region. Rafi et al. (2005) reported “ Illeis (Anchilleis) chappuisi Crotch ” (= Macroilleis chapuisi (Crotch 1874)) , from Pakistan and it appears to be an erroneous / unverified record as it is known only from Indonesia ( Li et al. 2010).
