Ectemnus pictipennis Esaki, 1931: 264 (sp. n.); Esaki, 1934: 1673; 1950: 256 (illustration, diagnosis) Teisocoris pictipennis (Esaki) : Hiura, 1959: 2 (n. comb).

Montandoniola pictipennis (Esaki) : Carayon, 1961b: 543 (note); Carayon & Ramade, 1962: 208 (note); Herring, 1966: 93 (syn. with M. moraguesi (Puton)) .

Type material examined: Holotype Ƥ, Japan, Kyushu, Wakasugiyama (province Chikuzen), 29–30.III.1930, Esaki, Hori, Fujino, Cho, Hashimoto, Yasumatsu ( KUEC) ( Fig. 14 ). Note: both antennae are damaged: segments IV and apical part of III are missing. Dissection of genitalia has been made by us.

Diagnosis (female Holotype). Body length: 2.3 mm. Head: antennal segments I and II dark brown, II lighter at base, basal part of III whitish, apical part of III and IV [missing on type specimen] pale yellow according to original description; labium dark, apex of segment II whitish, segment III whitish except apex dark. Thorax: lateral margins of pronotum nearly straight, lateral carinae well marked, expanded anteriorly; metapleural evaporative area damaged, ostiolar peritreme indistinct posteriorly ( Fig. 18 ); legs dark brown; foretibiae whitish (except extreme base dark); mesotibiae pale brown, whitish apically, lighter than hindtibiae, foretarsi whitish [other tarsi glued indistinct] (all tarsi pale yellow on the original description). Female genitalia ( Fig. 39 ): copulatory tube long, located on right and curved toward midline.

Male unknown.

Biological data. According to Esaki (1931), the species lives in the grasses. Hiura (1959) added the following data: “Miyamoto obtained a specimen beating a dead tree and Hama another under a pile of fallen leaves near water with Dryopid and Ptiliid beetles”.

Distribution. Known only from the type locality: Japan (Kyushu).

Comments. Herring (1966) considered that the synonymy of M. pictipennis with M. moraguesi was definitely realized by Carayon (1961b) and he agreed with him. In fact, in his paper, Carayon only suggested the synonymy as possible and he did not propose it formally because he had not studied the type specimen. Examination of the genitalia of the female holotype clearly shows that M. pictipennis is different from M. moraguesi and must be restored as a valid species.

M. pictipennis differs from M. moraguesi by the following characters: shape and location of the female copulatory tube (curved and inserted right to the base of the ovipositor, compare Figs. 5 and 19 to 38 and 39), coloration (mesotibiae light in M. pictipennis , dark in M. moraguesi ). It differs from M. confusa sp. nov. by a quite different female copulatory tube (compare Figs. 40 and 39 ); from M. ishikawai and M. bellatula , by the coloration pattern and copulatory tube; from M. sawtellense by the genitalia also being different.
