1. Accacidia obunca Cao & Dmitriev sp. nov.

( Figs 9 View FIGURE 9 , 25 View FIGURE 25 i–l)

Description. Ground color off white (specimens preserved in ethanol before examination) without distinct markings. Body thin. Head distinctly narrower than pronotum, crown fore margin broadly rounded apically, anteclypeus long. ( Figs 25 View FIGURE 25 i–l). Forewing ( Fig. 9a View FIGURE 9 ) with fourth apical cell wide and third apical cell narrow.

Male abdominal apodemes 2S ( Fig. 9c View FIGURE 9 ) narrow, extended to middle of sternite V. Anal tube appendage ( Figs 9d, e View FIGURE 9 ) directed ventrad, pointed and hooked apically.

Pygofer lobe ( Fig. 9d View FIGURE 9 ) with dorso-caudal angle produced, hind margin with small process medially. Subgenital plate ( Figs 9d, g View FIGURE 9 ) with outer margin rounded subapically, with about 2 macrosetae. Style ( Figs 9h, i View FIGURE 9 ) with apical margin slightly concave, preapical lobe with small process ventrad of apical part, only with sensory setae on preapical lobe. Connective ( Fig. 9j View FIGURE 9 ) with manubrium moderately wide, central lobe almost as long as lateral arms, apical margin slightly convex. Aedeagal shaft ( Figs 9 View FIGURE 9 k–n) narrowing towards apex, dorsal margin protruded near apex, with pair of short apical processes extended basad, with small tooth subapically on ventral margin of process; dorsal apodeme large, lamellate; preatrial process longer than shaft, apex curved caudad, smooth, without sculpture, connection between shaft and preatrial process wide and inflexible; gonopore subapical.

Measurement. Male length 3.70–3.75mm.

Material examined. Holotype: ♂, REPUBLIC OF CONGO, Dept. Pool, Iboubikro site, Lesio-Loun Pk, 340m, 03°16.020'S, 015°31.440'E, 29.viii.2008, coll. Braet & Sharkey. GoogleMaps Paratype: 1♂, same data as holotype except 03°16.196'S, 015°28.267'E, 25.viii.2008 GoogleMaps .

Etymology. The new specific epithet is derived from Latin adjective “ obuncus ” which means hooked, referring to the hooked anal tube appendage.

Diagnosis. The new species differs from most of the other species of the genus in having a longer and thinner body with the head narrower than the pronotum. In these respects, it is similar to two other species previously described from the Republic of Congo (Odzala): A. stehliki Dworakowska, 1974 and A. metcalfi Dworakowska, 1974 . The male genitalia are most similar to A. simillima Dworakowska, 1971 , but the style is concave on the apical margin and has a small process on the preapical lobe, the aedeagal shaft is longer, the apical processes of the shaft are longer and the connection between the shaft and the preatrial process is much wider.
