Dalpada brevivitta Walker, 1867 by original designation.

Holotype male, pinned, CHINA: Sichuan Province: Mianning County, Liangshan Prefecture, 29. VIII. 2008, Kai DANG leg. Paratypes: all pinned, CHINA: Sichuan Province: 1 female, same data as holotype; 1 male, with genitalia in a separate microvial, same data as holotype.

Rostrum reaching the middle of 3^rd sternum, pronotal humeral angles not elevated upwards, apical meeting trend of mandibular plates are all similar to Cahara tibetana. But Cahara tibetana has a distinct angular process before each eye along the lateral margin of mandibular plate, mandibular plates about equal to or slightly longer than clypeus. While in this new species, mandibular plates are always longer than the clypeus, lateral margins of head sinuate and with no angular process before eye.

Body size Male, length 16.0mm, width between humeral angles 8.0mm. Female, length 17.0mm, width between humeral angles 8.5mm.

Color and puncturing. Dorsum fuscous, darkly and thickly punctured, with several obscure patches formed by dense punctures: four or five longitudinal strips on the pronotum, five on the scutellum (one short oblique strip near each arcuate callus behind the fovea of scutellar basal angle, one patch on central disk, two short longitudinal stripes at the level of the posterior apices of frena), two or three patches on each corium. Scutellar apex paler and punctures finer. Calli on the anterior disk of pronotum ochraceous with punctures in the middle. Humeral angles piceous, tips a little pale, with several transverse furrows and wrinkles on the dorsal base. Hemelytral membrane fuliginous, except apices of veins paler. Head beneath black, except buccula and one obscure strip behind each antenniferous tubercle ochraceous. Thoracical pleura thickly and darkly punctured, each episternum with an ochraeous, laevigate and arcuate fascia distally. Mesosternum black strips laterally. Legs ochraceous, with irregular brown spots, tibiae paler in the middle third and darker in the apical third, first two tarsal segment and apex of the third one white dorsally. Ventral abdomen smooth at center, punctures gradually getting denser laterally. Middle third of each laterotergite with a transverse brown impunctate stripe.

Structure. Head. Mandibular plates longer than clypeus, apices with meeting trend but still separated, forming an incision before clypeus. Lateral lobes of mandibular plates are found angulate in the male holotype and the female paratype (Fig. 1a), but obtuse in the male paratype (Fig. 1b). Buccula with anterior angle not produced, gradually evanescent posteriorly. Antennae ochraceous, darker to the end, antennomere I paler except each lateral side, base of antennomere IV and basal third of antennomere V stramineous, IV> V>III >II>I in length. Rostrum reaching the middle of 3^rd sternum, apex of 1^st segment equal to the posterior end of buccula.

Thorax. Pronotum with anterior margin slightly convex in the middle, anterior angle produced laterad, anterolateral margins concave, crenulate along the anterior half, crenulation getting weaker posteriorly. Humeral angles horn-like, apices obtuse, slightly produced and not elevated upwards. Hemelytral membrane longer than the abdominal end. Peritreme groove shaped according to Kment and Vilímová (2010), which is narrow, long, curved, apex rounded, median furrow is well developed in most of its length. A narrow and long carina along the midline of mesosternum.

Abdomen. Connexiva exposed broadly, posterior angles sharp and produced. Mesial groove on ventral side not distinct.

Male genitalia. Ventral rim of pygophore with two separated processes on both lateral sides. Suspensory apodeme and infoldings of lateral rims developed. Paramere L–shaped, stem with a short basal process, apex of blade obtuse without any distinct process. Phallotheca cylindric, with a mesial process on the base of ventral side. Aedeagus with a pair of dorsal conjunctival processes, sclerotized and fingerlike, a trifurcate membraneous conjunctival lobe, a pair of ventral conjunctival processes, slightly sclerotized. Median penial plates oblong and narrow, about as long as the protrudent vesica.

Female genitalia. Paler in color, punctured on gonocoxites I and paratergites VIII, punctures on gonocoxites I finer. Mesial margins of gonocoxites I narrowly black, meeting each other along the basal halves, lateral margins of the fingerlike processes not vertical. Gonocoxite II with a transverse tumescent beam full of setae. Paratergits IX obtuse apically, slightly passing beyond the posterior margin of 8^th sternum. Paratergites VIII not protrudent apically.

The species name, incisura, refers to the longer mandibular plates that always leave an incision before clypeus. It’s feminine.

Buccula low, anterior angles pointed and protrudent, outer margins straight. Rostrum with 1^st joint extending beyond the buccula, apex reaching to the middle of 4^th sternum.

Thorax. Pronotum with anterior half depressed and posterior half tumescent, anterior margin broad, sinuate, slightly convex mesially, anterior angle small, angulate and produced laterad, anterolateral magins crenulate, humeral angles nodular, protrudent, elevated upwards. Scutellum longer than width, basal disk and longitudinal midline tumescent. Meso sternum flat with a mesial narrow carina. Peritreme similar to Cahara incisura. Hemelytral corium longer than scutellum, membrane extending beyond the abdominal end.

Abdomen. Connexiva exposed, posterior angles pointed and produced. Venter, from 3rd to 6th abdominal sternite, with a mesial shallow groove.

Male genitalia. Ventral rim of pygophore V–shaped excavated, sinuate along the margin but without distinct process. Suspensory apodeme and infoldings of lateral rims developed. Paramere L–shaped, stem broad with a small basal process, blade long with an apical process and a basal process, these two processes all directed caudad. Aedeagus with paired sclerotized dorsal conjunctival processes, a trifurcate membranous conjunctival lobe, and a pair of slightly sclerotized ventral conjunctival processes. Median penial plates oblong, apices obtusely angulate. Vesica slim, protrudent.

Female genitalia. Outer margins of gonocoxites I black, so are the apical halves of paratergites IX, pratergites VIII thickly punctured. Gonocoxites I strongly sinuate mesially, broadly and distinctly depressed in the middle of the lateral margins so the fingerlike processes bent dorsally and almost vertical. Apices of fingerlike processes reaching the apical third of paratergites IX. Gonocoxite II with a transverse tumescent beam. Paratergite IX base with a short oblique ridge, apex passing a little beyond the posterior margin of 8^th sternum. Paratergites VIII obtuse distally.

The name, nodula, refers to the bulbous, distinct nodular humeral angles of pronotum. It’s feminine.

See diagnosis of Cahara incisura sp. n. Besides, in this species, two processes on the ventral rim of pygophore connected basally, suspensory apodeme longer than those in the other two species, stem of paramere broad with two lateral margins not parallel. Gonocoxites I depressed along the lateral margin and fingerlike processes bent dorsally like Cahara nodula, but the transverse tumescent beam of gonocoxite II shorter in this species.
