description: Stirellus viridulus (Pruthi) comb. nov.
Material examined. Pakistan: 23, 2Ƥ, Tando Jam, 8.i.2008.
Remarks. Specimens compared to the original figures given by Pruthi. Described from several syntypes from: India, Kodaikanal Road Station, foot of Palni hills, 3–4-vii.29, H.S. Pruthi (ZSI) and other localities in India; types not examined.
New taxa
Bampurius pakistanicus sp. nov. (Plate 1, a; Figs. 1, 2)
Description. Length: 3, 4.8mm.
Yellow with brown markings as in Plate 1, a and Fig. 1 a–d. Vertex with a distinctively shaped brown mark from ocellus towards coronal suture; forewing with apex and reflexed costal veins brown.
Head subequal in width to pronotum; anterior margin angularly rounded. Vertex triangularly produced, slightly shorter than basal width; smooth. Face slightly longer than greatest width, shagreen; clypeus narrow, with lateral margins noticeably incurved at antennal pit; clypellus with sides concave, apex slightly wider than basal width and subequal to width of lora; antennae longer than width of head, bases at level near middle of eyes; antennal ledge absent; ocelli touching or nearly touching eyes.
Pronotum with lateral carina. Forewing macropterous; appendix extended to slightly beyond midlength of marginal vein of second apical cell; inner subapical cell open; two or three costal veins from outer subapical cell and an additional vein slightly more basad, reflexed; A1–A2 cross vein absent.
Male genitalia with pygofer with posterior margin incurved ventrally with two groups of stout setae and an internal medial bowed sclerotised band across lobes dorsally (Fig. 2 d). Valve moderately long.
Subgenital plate short, acute apically in ventral view, without digitate apex, macrosetae uniseriate near lateral margin; with a few short fine hairs laterally. Style broadly bilobed anteriorly, median anterior lobe short; apical apophysis elongate, digitate, apex turned laterally, crenulate; lateral lobe reduced.
Connective short, Y -shaped with stem as long as arms, apex bifurcate; articulated with aedeagus.
Aedeagus with shaft turned slightly to one side of socle, elongate, cylindrical, recurved posteriorly, slightly expanded to near apex in lateral view then tapered to acutely rounded apex, without processes, gonopore apical on dorsal surface; basal apodeme moderately long, tapered to near apex then slightly widening apically in dorsal view.
Female genitalia with pregenital sternite with posterior margin strongly incised medially.
First valvula lanceolate, tapered to acute apex; dorsal sculpturing pattern concatenate; reaching dorsal margin. Second valvula moderately broad, expanded slightly subapically; dorsoapical teeth over distal half, large, with denticles on posterior edge; dorsal sclerotised area present, saddle-shaped.
Material examined. Holotype 3, Pakistan: Tharparkar, 7.viii.2007, I. Khatri (BMNH); paratypes: 53, 1Ƥ, same data as holotype (BMNH and IKC).
Remarks. The shape of the aedeagus in this species is similar to other members of the genus e.g. B. eberti (Dlabola, 1964), B. bahukalatus Dlabola (1977), B. striatus Dlabola (1977) and B. trilunulatus Dlabola (1984). From these species it differs in the slightly broader aedeagal shaft subapically (Fig. 2 g) and the incised female pregenital sternite (Fig. 1 e). One other species of the genus, B. melichari (Distant), lacks the aedeagus in the only known male (see Webb & Viraktamath, 2009). We figure the pygofer of pakistanicus in posterior aspect (Fig. 2 d) to show the lobe-like infolding of the interconnecting membrane, with two groups of spinelike setae on each lobe, and a transverse dorsal sclerotized band, structures that have not previously been figured for the genus. The measurement given is taken from the type and only complete specimen.
Neolimnus quadricornis sp. nov. (Plate 1, b; Figs 5, 6)
Description. Length: 3, 3.6mm; Ƥ, 4–4.2mm
Yellow with brown markings as in Plate 1, b; Figs 5 a, c. Vertex with a distinctively shaped brown mark from ocellus towards coronal suture and a triangular shaped mark each side of midline subapically and forewing with a brown spot in outer apical cell.
Head subequal in width to pronotum, fore margin angularly rounded to face. Vertex triangularly produced, slightly shorter than basal width, shagreen. Face slightly longer than greatest width, shagreen; clypeus moderately narrow, with lateral margins not noticeably incurved at antennal pit; clypellus with sides concave, apex slightly wider than basal width and subequal in width to lorum; antennae longer than width of head, bases at level near middle of eyes; antennal ledge absent; ocelli touching eyes. Pronotum with lateral carina. Forewing macropterous; appendix extended to slightly beyond midlength of marginal vein of second apical cell; inner subapical cell open, outer subapical cell pertiolate, outer vein from fourth apical cell reflexed, costal vein from outer subapical cell reflexed; A1–A2 crossvein absent.
Male genitalia with valve relatively long. Subgenital plate short, broadly rounded apically in ventral view, without digitate apex, stout processes from inner dorsal margin directed dorso laterally; macrosetae uniseriate, near lateral margin and across plate subapically; with a few short fine hairs laterally and dorsoapically. Style broadly bilobed anteriorly, median anterior lobe pronounced; apical apophysis long, digitate, apex crenulate; lateral lobe reduced. Connective large, Y -shaped with stem twice as long as arms; articulated with aedeagus. Aedeagus with shaft moderately long, cylindrical, curved dorsally, tapering to narrowing rounded apex, with a slight lateral ledge (visible in ventral view, Fig. 6 f), gonopore apical, two pair of moderately long lateral processes directed dorsally, one at midlength from ventral surface and one slightly more distal arising near ventral margin in lateral view; basal apodeme short and robust widening apically in dorsal view.
Female genitalia with pregenital sternite with posterior margin with a medial lobe. First valvifer with lobe-like ventral posterior extension. First valvula lanceolate, tapered to acute apex with numerous dorsal teeth over distal two thirds, more basal teeth positioned slightly on more medial surface (Fig. 5 g); dorsal sculpturing pattern concatenate; reaching dorsal margin. Second valvula moderately broad, gradually tapered; dorsoapical teeth over distal third, large, with denticles on posterior edge; dorsal sclerotised area present, saddle-shaped.
Material examined. Holotype 3, Pakistan Tharparkar, 7.viii.2007, I. Khatri (BMNH); paratypes: 13, 7Ƥ, same data as holotype (BMNH, IKC).
Remarks. This species is similar to the two other species of the genus, N. egyptiacus (Matsumura) and N. superlaminatus Dlabola, in external appearance and from the former species in the unusual posterior lobe of the first valvifer and apically twisted first valvulae with dorsal teeth, the latter teeth reminiscent of those found in the unrelated Cicadulina (see Knight & Webb, 1993, fig. 142). It is also similar to egyptiacus, which is the only other species known from the male, in the short subgenital plate with an unusual inner dorsal process (Figs 6 d, 7g). It differs from this species by its more elongate pygofer and very different aedeagus with a more elongate and evenly tapered shaft (compare figs 6g and 7e) with two pair of lateral process.
