Neojurtina Distant, 1921

Neojurtina Distant, 1921: 68 (original description). Type species: Neojurtina typica Distant , by monotypy.

Neojurtina : Hoffmann (1932): 8 (list); Tang (1935): 339-340 (catalogue); Stichel (1962): 247 (list of species, references and distribution); Hsaio et al. (1977): 93, 102, 116 (key, description, distribution); Lin & Zhang (1993): 118 (key).

Additional description: Structure: Head ( Images 3–4) slightly sloping downwards, nearly as long as width across compound eyes; lateral margins more or less straight, not reflexed. Mandibular plates nearly as long as or slightly shorter than clypeus, apex of mandibular plates rounded; dorsoposterior surface of head between ocelli and base of clypeus slightly gibbose. Compound eyes large, rounded, protruding out of head outline in most of their width. Ocelli small, situated posteriorly behind eyes. Antenniferous tubercles indistinct, scape visible from above. Antennae slender and 5-segmented, antennal segments from shortest to longest: I<IIa<IIb≤III>IV; antennal segment I cylindrical, shortest and stoutest, nearly as long as apex of head ( Image 3); antennal segments IIa–IV, cylindrical and slender. Bucculae short, rounded anteriorly, partially covering anterior three-quarters of labial segment I. Labrum narrow and elongate ( Image 4). Labial segment I stout, slightly surpassing posterior margin of bucculae; apex of labium reaching abdominal ventrite II.

Pronotum ( Image 1). Anterior pronotal margin deeply concave; anterolateral angles rectangular to acutangular, with minute laterally directed tooth; lateral margins nearly straight. Humeri angulate; posterolateral margin of pronotum sinuate, posterolateral angles of pronotum nearly rounded; posterior margin of pronotum slightly concave medially. Anterior part of pronotal disc slightly sloping downwards, without median ridge; posterior part of pronotal disc horizontal and slightly convex.

Scutellum ( Image 1) roughly triangular, longer than wide at base;lateral sides slightly incised at apices of frena (at third from apex); apex of scutellum not surpassing outer distal angles of corium, widely rounded. Disc of scutellum slightly gibbous at anterior two thirds.

Hemelytra. Clavus narrow and elongate and roughly triangular and uniformly punctate. Corium with inner distal angles arcuately rounded, outer distal angles acutely extending downwards and outlining anterior half of membranous region. Membrane translucent, widely rounded apically, surpassing apex of abdomen. Membrane bearing 8–9 nearly parallel and simple veins, without reticulate venation.

Thoracic pleuron and sternum ( Image 2). Procoxae placed close to each other; meso- and metacoxae remote from procoxae; mesosternum with narrow, median, longitudinalcarina( Image5);metasternumwithprominent median, longitudinal carina, grooved and in apposition to extreme apex of tubercle on abdominal ventrite III, metasternal carina acutely produced downwards laterally. Ostiole semiovate, accompanied with elongate, semispindle-shaped peritreme of the ruga shape sensu Kment & Vilímová (2010) ( Image 6); evaporatorium large, well developed on metapleuron, metathoracic spiracle long, distinctly visible in ventral view.

Legs ( Image 2) long;profemora as long as mesofemora, metafemora longest; all femora nearly cylindrical, unarmed and rounded in cross section. All tibiae slender than appropriate femora, tibiae narrowly cylindrical and rounded in cross section, lacking dorsal longitudinal groove. All tarsi with segment II shortest, segment I longest but shorter than segment I and II combined; all tarsal segments dorsally regularly rounded, not grooved.

Pregenital abdomen ( Image 2). Connexivum slightly exposed;posterolateral angles of each abdominal ventrite angulate or with minute tooth. Abdominal venter slightly convex medially, strong median longitudinal groove beginning from ventrite III–VII. Ventrite III with one strong tubercle or short angulate process possessing strong median longitudinal groove. Spiracle on ventrite II covered by metapleuron. Spiracle placed above spiracular outline on each ventrite and a pair of trichobothria situated slightly mesad to each spiracle.

Male genitalia: Unknown.

Female genitalia ( Images 7–8). Terminalia ( Image 8). Valvifers VIII ventrally almost meeting each other, roughly quadrangular with inner lateral margin straight; valvifers IX fused and inverted trapezoidal in shape; laterotergite IX finger-like, not reaching apex of abdomen; laterotergite VIII nearly rhomboidal with caudal margin bearing two angulate projections, laterotergite VIII dorsally encompassing laterotergite IX and segment X and medially fused. Spermatheca ( Image 7). Median dilation not distinct rather with short proximal dilation; intermediate part of spermatheca short, proximal flange of same size as that of distal flange; apical receptacle small, rounded with three elongate, finger-like processes, all distinctly surpassing distal flange.

Differential diagnosis:The genus is easy to recognize by combination of the stout median tubercle on abdominal ventrite III and deep median longitudinal groove continuing from ventrite III to the rest of the abdominal ventrites up to ventrite VII, and also the strongly grooved metasternal carina in apposition to median tubercle on abdominal ventrite III.

Etymology: In the original description of Neojurtina, Distant (1921) did not mention anything about the origin of the genus name other than remarking that this genus is allied to Jurtina Stål, 1868 (now junior synonym of Bathycoelia Amyot & Serville ). The gender of the name is feminine, as it is apparent from the feminine form of the specific adjective typica .
