description: Neotetricodes xiphoideus Chang et Chen, sp. nov.
(Figs 3–4, 33–51)
Description. Measurements. Body length (from apex of vertex to tip of tegmina): male 5.8 mm (N =1), female 6.0– 6.2 mm (N=2); Tegmen: male 4.8 mm, female 5.0– 5.5 mm.
Coloration. General color (Figs 3–4) brown. Vertex (Fig. 33) brown, eyes reddish brown to brown; antenna dark brown. Frons (Fig. 34) brownish black. Pronotum (Fig. 33) brown, with numerous pale brown mottling; mesonotum brown. Tegmina (Fig. 3) brown, suffused with irregular black spots. Hind wings translucent, gray. Legs (Fig. 9) brown, tips of spines on hind tibiae and tarsi black.
Head and thorax. Head (Fig. 33) including eyes narrower than pronotum (0.74: 1.00). Vertex (Fig. 33) shorter in midline than wide at base (0.47: 1.00), strongly depressed; disc of vertex with median carina. Frons (Fig. 34) flat, disc slightly depressed, basal margin arched, apical margin obtusely rounded, lateral margins ridged, lateral margins incurved below level of sockets of antennae, longer in middle than the widest breadth (1.20: 1.00), with median and lateral carinae. Pronotum (Fig. 33) with median carina obscure, lateral carina not reaching the posterior margin. Mesonotum (Fig. 33) triangular, with median carina and lateral carinae obscure. Tegmina (Fig. 36) elongate, 2.4 times as long as maximum width, ScP and R forked near 1/4 base, MP four branched, MP1+2 bifurcate, reaching the apical margin, MP3+4 bifurcate at middle part, uniting near apical margin, CuA not forked, simple, CuP present, Pcu and A1 uniting in basal 2/3 of clavus. Hindwings (Fig. 37) deeply incised on apical margin into two big lobes, with a network of veins, anal lobe reduced. Hind tibiae (Fig. 9) each with 2 spines, spinal formula of hind leg 8 (10) –10–2.
Male genitalia. Anal tube (Fig. 40) in dorsal view sub-quadrate, relatively short, with two lobes near apical margin. Anal style (Figs 38, 40) short, located at the base 1/4 of anal tube. Pygofer (Fig. 38) narrow and curved in lateral view, subquadrate, anterior margin concave on dorsal 1/3, posterior margin moderately convex. Genital styles (Figs 38–39) moderately long, dorsal margin producing an obscure triangular lobe before capitulum. Phallobase (Figs 41–42) with dorsal lobe with one trapeziform process and irregular finger-like processes near base in lateral view; ventral lobe relatively long, not reaching the tip of dorsal lobe; in ventral view ventral lobe irregularly quadrate, the apical half broad, basal half lateral margins parallelling. Aedeagus with xiphoid processes near middle, acute apically with its apex directed caudad in lateral view (Figs 41 a, 42a).
Female genitalia. Hind margin of sternum VII widely concave, with two horned prominence near mediline (Figs 45, 47) in ventral view. Anal tube (Fig. 46) sub-rectangular, truncate apically, distinctly longer in midline than the widest portion(1.66: 1.00), anal style short, located at the basal 1/4 of anal tube. Hind margin of gonocoxa VIII with endogonocoxal lobe indistinct, endogonocoxal process gradually narrowing (Fig. 48). Anterior connective lamina of gonapophyses VIII (Fig. 48) with 3 teeth bearing 3 keels in lateral group and 3 teeth in apical group. Posterior connective lamina of gonapophyses IX (Figs 49–50) sub-triangular, relatively broad, lateral field with one triangular process (Fig. 49 b) on lateral margins; sublateral field with coralloid processes (Fig. 49 a) between lateral margin and median field, median field with lingulate prominence (medial dorsal process) (Fig. 49), the apical part gradually tapering, the apical margin with median incision; posteroventral lobes bent at obtuse angle (posterior ventral lobes) (Fig. 49). Gonoplacs (Fig. 51) without keels.
Type material. Holotype: ♂, Huanglianshan National Nature Reserve (22°54´N, 102°12´E), Lvchun, Yunnan Province, China, 14 Aug. 2014, Z.-X. Zhou (IEGU); paratypes: 1♀, Huanglianshan National Nature Reserve (22°54´N, 102°12´E), Lvchun, Yunnan Province, China, 5 Aug. 2012, S.-Y. Xu (IEGU); 1♀, Huanglianshan National Nature Reserve (22°54´N, 102°12´E), Lvchun, Yunnan Province, China, 5 Aug. 2012, S.-Y. Xu (BMNH).
Host plant. Unknown.
Distribution. China (Yunnan).
Etymology. This new species is named after the presence of aedeagus with xiphoid processes near middle, acute apically, its apex directed caudad in lateral view.
Remarks. This new species is similar to N. longispinus Chang et Chen, sp. nov., but can be distinguished from the latter in: Phallobase (Fig. 49) with dorsal lobe with one trapeziform process and irregular finger-like processes near base in lateral view; ventral lobe irregular quadrate, the apical half broad, basal half parallelling in ventral view (Fig. 50). Aedeagus with xiphoid processes near middle, its apex directed caudad in lateral view (Figs 49–50).
