Parazimmermania BAI, HEISS & CAI, 2024

Parazimmermania BAI, HEISS & CAI gen. nov.

T y p e s p e c i e s o f t h e g e n u s: Parazimmermania tamdaoensis BAI, HEISS & CAI nov.sp.

D e s c r i p t i o n: Micropterous. Medium sized (6-7.7). Body elongate ovate, reddish brown. Head, antennae and lateral parts of thorax, abdomen and legs beset with brush-like stiff erect apically curved hairs.

H e a d: About as long as wide across eyes; clypeus and genae short, not produced beyond apex of labial atrium; antenniferous tubercles stout, conical, shorter than clypeus; eyes small, semiglobose, with convex face; postocular borders with dense erect hairs, converging posteriorly to constricted neck; antennae long, first segment stout and clavate, longer than cylindrical second segment, third cylindrical and longest, fourth fusiform and shortest; rostrum arising from a slit-like atrium, shorter than rostral groove.

T h o r a x: Pronotum attenuated anteriorly, anterolateral lobes not protruding; collar ringlike; pronotal disc with longitudinal deep impression. Mesonotum with distinct scutellum, laterally deeply depressed and bulbous anterolateral wingpads; metanotum fused to mtg I and II into an elongate plate with longitudinal ridge and 4 (2+2) oval glabrous callosities; the fusion line is marked by a thin bisinuate carina; deltg I + II fused, produced forward to mesonotal wingpads.

A b d o m e n: Deltg III-VII distinctly raised laterally, rather bare on inner half, with stiff erect pilosity on outer half; tergal plate consisting of mtg III to VI fused into a subquadrangular central plate, with a median longitudinal ridge and the basic pattern of large oval callous spots and dots; mtg VII strongly elevated posteriorly in male and slightly depressed in female. Paratergites VIII clavate or dentiform. Dorsal scent gland openings small.

V e n t r a l s i d e: Prosternum raised and with dense erect hairs, disc of meso- and metasternum flattened medially; spiracles II+III lateral, IV sublateral and barely visible from above, V-VII ventral, VIII terminal.

L e g s: Long, slender; fore tibiae with preapical spine-like combs.

D i s t r i b u t i o n: Vietnam (Vinhphuc province).

E t y m o l o g y: The generic name reflects the similarity to the Oriental flat bug genus Zimmermania ,>para<(Latin) = near to.

R e m a r k s: The genus resembles Zimmermania USINGER, 1948 in general body plan, but differs by the closed labial atrium with slit-like opening (vs. labial atrium open in Zimmermania ); in the key to genera of the Oriental, Australian and Pacific Carventinae ( KORMILEV 1970) , it runs to Chelysosoma KORMILEV, 1956, but this genus lacks a distinct scutellum and differs by other position of spiracles: II sublateral and visible from above,

III-VII ventral (vs. II+III lateral, IV sublateral but visible from above, V-VII ventral, VIIII terminal in Parazimmermania ).
