Female.
Body length. 6.0-6.9 mm.
Colour. Black; following parts unpigmented, pale: apical maxillary palpomeres; posterodorsal margin of pronotum in lateral parts; tegulae (except lateroproximal part); median band or patch of pro-, meso-, and metatrochantellus; profemur apically; protibia in anterior and partly posterior aspects; mesotibia partly in anterior and posterior aspects; metatibia basally; tarsomere 1 of hind leg basally; paired patches on abdominal terga 2-5; at least partially posterior margins of terga (tergum 10 dorsally more widely) and sterna; and cenchri. Labrum from yellowish-brown to blackish.
Head. Head behind eyes in dorsal view subparallel sided; postocellar area trapeziform, its length equal to or longer than 2 times diameter of lateral ocellus; distinct and diverging lateral postocellar furrows going from ocelli towards occiput at least to the distance of ocellus diameter; area between frontal crests clearly exceeding the level of crests in dorsal view; postocellar area with indistinct punctures and interspaces, more or less glossy; punctures more regular on temples and postocular area, face with more irregular punctures; wrinkled interspaces more prominent on frontal area; clypeus with rough irregular punctures, more or less fused; ocellar and postocellar area convex, slightly raised; clypeus tridentate with median keel distinct mostly in anterior part of clypeus only, median tooth smaller than lateral teeth; malar space about equal to or shorter than distance between antennal sockets; frontal ridge V-shaped; pit in central part of frontal field present; median ocellus surrounded by groove, with short distinct longitudinal furrow anteriorly, and with similar but mostly less distinct furrow posteriorly. Maximal length of temple 1.2-1.4 times greater than its minimal length; flagellum 1.9-2.0 times longer than breadth of head.
Thorax. Mesoscutellum, mesoscutellar appendage, and metapostnotum more or less glossy, almost impuctate or with indistinct shallow punctures; metascutellum with irregular fine punctures; punctures on mesoscutum more evident on lateral and anterior regions of the median lobes, fading towards central regions; mesepisternal punctures variable between specimens, from rather weak with intespaces almost glossy to more distinct with sculptured, interspaces; mesepimeron with setae on posterior part; metepisternum with evenly distributed setae; metepimeron in central part without setae; distance between cenchri 1.1-1.4 times of cenchrus width; wings hyaline, venation brownish, becoming paler near junction to thorax; closed cell M in hindwing present; tarsal claws with conspicuous subbasal tooth.
Abdomen. Terga on most parts with transverse keel-like sculpticells and with short setae (about half of lateral ocellus diameter), sometimes with shallow punctures at median parts of terga 2-4; posterior parts of terga (6) 7-9 (occasionally terga 3-10) at median line with small more or less triangular pale regions; ventral margin of valvula 3 slightly bending towards apex, slightly longer than valvifer 2; serrulae of valvula 1 as in Fig. 21, number of serrulae 15-16.
Male.
(Mostly the differences compared to female are given).
Body length. 4.8-5.6 mm.
Colour. Unpigmented, whitish or yellowish brown: anterolateral (seldom also posterolateral) margins of tegulae; protibia in anterior aspect, often partly also in posterior aspect; mesotibia partly in anterior aspect; outer margins of harpes; and paired patches on abdominal terga 2-(3)/4/(5).
Head. Area between frontal crests reaching or slightly exceeding the level of crests in dorsal view; malar space less than or equal to distance between antennal sockets; length of postocellar area about 2 times of lateral ocellus diameter; maximal length of temple 1.25-1.45 times greater than its minimal length; flagellum 2.3-2.6 times longer than breadth of head.
Thorax. Distance between cenchri variable, up to 2 times width of cenchrus. Tarsal claws with minute subbasal tooth.
Abdomen. Tergum 8 with indistinct tergal hollows which form semioval or semicircular depression reaching 1/3-1/2 of tergum length and sometimes possessing indefinite central procidentia. Posterior margin of sternum 9 round; penis valve as in Fig. 31.
Taxonomic affinities.
Based on the similarities in penis valves, the closest species is Empria sulcata Wei & Nie, 1998 from China (see http://www.morphbank.net/?id=643394). While the penis valves of both species can easily be distinguished, the distinctly concave dorsal margin of valviceps of these species is a unique characteristic within Empria . Serrulae of the two species are clearly different (cf. Fig. 21 and http://www.morphbank.net/?id=700325). Externally the species can mainly be distinguished by colouration: in Empria sulcata tegulae are completely pale and legs extensively yellowish, while in Empria honshuana tegulae are at least partly and legs predominantly black.
Host plants.
Unknown.
Distribution.
Japan (Honshu).
Etymology.
The species name refers to the type locality, Honshu, the main island of Japan.
