Capnogryllacris (C.) fasciculata fasciculata ( Pictet & Saussure, 1891)

Figs. 47I , 48L , 50H

Material examined. Indes orientalis— 1 female (type) (Genève (MHNG)); East Malaysia: Sarawak, River Baram , 1.i.–31.xii.1894, leg. W. Kükenthal— 1 male (Frankfurt SMF) ; Indonesia: Kalimantan Timur, Midden Oost Borneo 157, 11.x.1925, leg. H.C. Siebers— 1 female, 1 male (Wien NHMW) .

Diagnosis. Large species with wide tegmen. On the tegmen, media receives a short, oblique connection branch from radius thus that MA+RS become fused and divide in apical third; cubitus anterior is single branched at base, after division into two branches, the anterior branch receives a connection vein from media anterior and then divides again into MP and CuA1, while CuA2 does not further divide. Thus, tegminal venation largely agrees with that of C. elongata . Coloration of face similar to that of C. elongata : yellowish brown; antennal scrobae, a wide vertical band below compound eyes, margins of clypeus and labrum and maxillary palpi dark brown ( Fig. 48L ). Characteristic are the red bands along the cross veins of the hind wings while the centers of the cells and a narrow line along the cross veins are white ( Fig. 47I ). The male ninth abdominal tergite is strongly setose, provided with a pair of oval swellings in apical area and furrow in midline; from each oval swelling a process with moderately swollen basal half and narrow apical half is pointing medio-apicad; tip of process obtuse. Male subgenital plate wider than long with central area moderately projecting, projecting area with medial furrow and obtuse-angularly excised tip; both apico-lateral angles strongly excavated with conical styli ( Fig. 50H ).

Description. Large species. Head: Face ovoid; forehead nearly smooth with scattered impressed dots and fine transverse riffles; fastigium verticis little wider than scapus, separated by a fine transverse furrow from fastigium frontis; ocelli distinct; subocular furrow absent ( Fig. 48L ).

Wings nearly reaching tip of ovipositor and end of stretched hind tibiae ( Fig. 47I ). Tegmen: Radius forks several times in apical area. Media anterior free from base; at about end of basal quarter receives a short connection vein from R, the RS, with which it is fused to apical third where MA+RS divide into RS and MA; RS then fuses a few times in apical area while MA remains unbranched in the further curse; cubitus anterior at base with a single branch that forks into two veins, the anterior branch makes a curvature and receives an oblique connection vein from MA+RS and shortly after divides again into two parallel branches, MP and CuA1, while the posterior branch (CuA2) does not divide further; cubitus posterior free and uni-branched throughout; with 4 anal veins, the last two with common stem.

Coloration. General color uniformly brown. Face in middle yellow; fastigium, base of antennae, towards genae, mandibles and lower part of labrum red brown, ocelli and palpi yellow. Tegmen along anterior and posterior margin semi-transparent white with yellow veins, in basal third little darker; along central area behind basal third surface reddish grey with pale veins and veinlets; hind wing semi-transparent white with dark veins; cross-veins rather pale, bordered on both sides with red bands, towards rim red color filling almost the whole cells.

Male. Ninth abdominal tergite strongly setose, globular with medial furrow, near hind margin divided and provided on both sides of midline with a large compressed faintly sinuate process with subobtuse tip ( Fig. 50H ). Subgenital plate rather short and wide, with weak medial furrow and basal margin angularly excised; apical margin wide roundly excised on both sides and in middle with a process with subacute latero-apical angles and concave apical margin; styli inserted in wide, rounded excisions between lateral margins of subgenital plate and medial process and largely surpassing tip of apical process.

Female. Seventh abdominal sternite wider than preceding sternites with truncate apical margin and a tiny pit before margin; between sternite and subgenital plate with a transverse groove. Subgenital plate with basal margin little elevated; with medial furrow, lateral margins convex, apical margin slightly bi-lobate. Ovipositor elongate; tip subacute.

Discussion. This species is included because of its strange venation of tegmen, in which the radius sector is obviously fused for a rather long distance with the basically free media anterior. This condition was found in all four specimens studied. In other characters, especially the male abdominal apex, the species fully agrees
