Ishiharella iochoui Dworakowska, 1982 ( Figs. 4, 7, 8 , 29-43 )

Ishiharella iochoui Dworakowska, 1982: 55 ; Qin & Zhang, 2004: 115.

Ishiharella scitula Qin & Zhang, 2004: 116 , syn. nov.

Description. Body length: male (HOLOTYPE of I. scitula Qin & Zhang ) 4.0 mm.

Color. General color (HOLOTYPE of I. scitula Qin & Zhang ) orange brown. Basal trapezoid patch of vertex brownish black, anteriorly with a brown line and linked to the pentagonal dark patch medially at the joint of vertex and face ( Fig. 7 ), sublateral stripes near eyes greyish and brownish at the base of face ( Figs. 4, 7 ). Eyes grayish black ( Figs. 4, 7, 8 ). Frontoclypeus with a longitudinal sordid stripe medially, not reaching apex of frontoclypeus, anteclypeus blackish apically, rest of area of face brown ( Fig. 4 ). Pronotum with the sinuate transverse depression slightly pigmented ( Fig. 7 ). Scutellum black apically, scutoscutellar sulcus brown ( Fig. 7 ). Forewing yellowish brown ( Figs. 7, 8 ).

Male Genitalia. Basal abdominal sternal apodemes surpassing half of segment 4, apically narrowed ( Fig. 37 ). Male pygofer brown, elongated in lateral view, narrowed in apical 2/5, dorsal margin almost straight, posterior margin truncated dorsally and constricted ventrally, terminally with 8 rigid microsetae on each side of lobe, caudoventral protrusion of pygofer short, in lateral view not surpassing the end of pygofer side, in dorsal aspect skeletonized and incised subbasally ( Figs. 29, 30 ). Subgenital plates separated subbasally, B-group setae (37-41) in 5-6 irregular rows, D-group (7-12) scattered in 2-3 rows, C-group setae (11-13) uniseriate on the lef side but biseriate near apex on the right side ( Fig. 33 ). Paramere sinuate, broad at base, bifurcated at apex and bearing a rigid tooth basad of bifurcation ( Fig. 35 ). Aedeagal shaf short, expanded basad in profile, gonopore terminus on the ventral side, basoventral protrusion of aedeagus long, strongly curved submedially, apicad of which are developed processes, the ventral process with a distinct cavity which is linked with the connective basoventrally, caudoventral margin of the cavity with an additional flake-like struc- ture, apical processes paired, spine-like, narrowing in distal half and slightly divergent in ventral aspect ( Figs. 31, 32 ). Connective trapezoidal ( Fig. 34 ). Anal tube process short, truncated at apex ( Fig. 36 ).

REMARKS

Dworakowska (1982) erected Ishiharella iochoui based on a single male from southern China (Zhejiang Province) (see the re-illustrations afer Dworakowska in Figs. 38-43 in this paper). Qin & Zhang (2004) established I. scitula based on a single male collected from southern China as well (Hunan Province). Qin & Zhang noted “ I. scitula is similar to I. iochoui Dworakowska , but differs from the latter by the pygofer long with hind margin truncated in lateral view, by the apical process of basal projections of aedeagus flat and sub-parallel with 2 long apical processes in dorsal view and by the connective nearly trapezoidal rather than ‘V’-shaped as the latter”. Afer examining the holotype of Ishiharella scitula , we suggest these differences represent variability within one species, and therefore treat the 2 taxa as synonyms.

DISTRIBUTION

China (Zhejiang, Hunan) .
