Ishiharella paradentata Lu & Qin , sp. nov. ( Figs. 44-61 )

Description. Size. Male 4.6-4.8mm, female 4.7mm.

Color. General color red brown. Vertex sordid orange, medially with a small blackish patch on each side, basal patch of vertex brown, anteriorly with a brownish line and linked to the pentagonal dark patch medially at the joint of vertex and face ( Fig. 44 ), vertex sublaterally near eyes with a visible brown stripe which is extended to the base of face ( Figs. 44, 46 ). Eyes dark ( Figs. 44-46 ). Frontoclypeus brown, medially has a longitudinal stripe, yellow brown, anteclypeus black apically ( Fig. 46 ). Pronotum centrally blackish, laterally with a black sinuate transverse depression on each side, basal angles red ( Fig.44 ). Scutellum with the central trapezoidal patch anteriorly and its apex black, scutoscutellar sulcus black brown ( Fig. 44 ). Forewing reddish basally and brown apicad ( Figs. 44, 45 ). Abdomen black. Legs sordid. Coloration of female same as male except abdomen brownish red, ovipositor brown.

Male Genitalia. Basal abdominal sternal apodemes reaching to end of segment 3, apically narrowed ( Fig. 47 ). Male pygofer brown, apical half strongly narrowed dorsally, with long fine setae caudally and rigid microsetae caudoventrally,pygofer caudoventral protrusion fairly long,in lateral view significantly surpassing the end of pygofer side,narrowing distad with pointed apex,ventrally bearing a tooth in middle ( Figs.48,50 , 54,55 ).Subgenital plates separated in basal 2/5, B-group setae (28-31) in 5-6 irregular rows,D-group setae (5-7) in about 2 rows,C-group setae (10-11) uniseriate in most part, subapically arranged in 3 rows on both sides ( Fig. 58 ). Paramere distinctly longer than pygofer, broad at base and narrowing apicad, apex spirally twisted, subbasally adorned with 4-5 teeth laterally ( Figs.48, 49 , 54, 60 ). Aedeagal shaf tubular, slightly broadened and curved caudad toward apex, caudal margin incised basally, dorsally bearing 4-5 small teeth, gonopore terminal on ventral side, dorsoatrium shorter than shaf, skeletonized basally and membranous apically, basoventral protrusion of aedeagus slender, sinuate, slightly longer than shaf, subbasal cavity distinct, apically bifurcated ( Figs. 48, 49 , 54, 56, 57 ). Connective lamellate caudally and crimped basally, caudal margin concave medially ( Fig. 59 ). Anal tube process skeletonized,strongly tapered and curved toward apex, tuberculate subapically ( Figs. 48, 49 , 54, 61 ).

ETYMOLOGY

The species epithet is derived from the combination of “para–” and “dentata ” which refers to the similarity of this new species to Ishiharella dentata Qin & Zhang, 2004 .

TYPE MATERIAL

HOLOTYPE male CHINA: Zhejiang, Tianmu Mountain , 25-VII-2011, L. Lu . PARATYPES. 1 male, Fujian, Wuyi Mountain, Dazhulan , 25-VII-2006, M.X. Yang ; 1 male 1 female, Jiangxi, Suichuan , 13-VIII-2004, C. Wei & M.X. Yang ; 1 male, Jiangxi, Suichuan , 10-VIII-2004, C. Wei & M.X. Yang .

REMARKS

This new species is similar to I. dentata Qin & Zhang , but differs in male genitalia (features of I. dentata in parentheses): dorsoatrium of aedeagus present (dorsoatrium absent), aedeagal shaf slightly curved dorsad and with 4-5 small teeth apically (aedeagal shaf curved ventrad apically and serrated in most part), caudoventral protrusion of pygofer significantly surpassing the end of pygofer side, sinuate, ventrally bearing a tooth medially (caudoventral protrusion slightly surpassing the end of pygofer side, curved ventrad and without teeth).

DISTRIBUTION
