Genus Campanacella Handschin

Campanacella Handschin, 1961 . Type species: Mаntispа hаmiltonellа ( Westwood, 1867) , by original designation.

Distribution: Oriental: India, Indonesia, Malaysia.

Diagnosis ( Fig. 5 ): Campanacella can be distinguished from all other Oriental and Palearctic genera by the peculiar formation of cu-m in the forewing ( Fig. 5b ). The cu-m is fused with M to form a distinct anteriorly directed loop touching R posterior to the origin of the costal space. The wings are always without pigmentation and the pronotum is at least 1½ times the length of the pterothorax ( Fig. 5d ).

Head: vertex with slight longitudinal ridge from the interantennal space to the occiput, flattening out laterally towards the ocular margin, postocular margin narrow, interocular space at anterior margin of scape distinctly narrower than width of eyes; scape usually lacks setae but a few may be present, flagellum length shorter than prothorax, flagellomeres simple/unmodified, similar in length than width, squircular in shape, each antennule with multiple whorls of anteriorly directed setae, flagellum lacks pale band in distal third.

Thorax ( Fig. 5a and c ): anterior margin with dorsoanteriorly directed cusp, pronotal shape of mid-section almost cylindrical, regular corrugation in dorsal view, lateral surfaces with long sparsely distributed setae; maculae pigmented and flattened, dorsolaterally directed (away from medial plane); posterior to maculae pronotum gradually decreases in width up to midway of mesozone, then increases in width; dorsal cusp anterior to prescutum inconspicuous if compared to corrugation on dorsum; prothorax longer than pterothorax; ventral outline of pronotum in lateral view straight; pterothorax: lacks setae but pubescent (velvet appearance), mesoscutal furrows conspicuous, meet at prominent central furrow, central furrow shaped as laterally compressed conical pit; mesoscutellum triangular, terminates just posterior to central furrow.

Legs: meso- and metatarsus with segment I longer in length than segments II–IV combined; segment IV the shortest; metatarsus with segment I similar in length than segments II–IV combined; segment II–IV similar in size; segment V slightly globose anterodorsally; meso- and metatarsal claws consisting of four to six teeth, with a collective rounded shape (middle teeth not distinctly longer, similar in length).

Wings: wings hyaline, unpigmented; pterostigma unmodified. Forewing: costal space terminating just basal to r-rs1; pterostigma commencing midway of RS2, terminates midway of RS3; sc-ra crossvein distinctly less than half the length of RS3, c-ra crossveins distal to pterostigma one, rarely two or three, A3 simple, A1 and A2 fused basally, CuP slightly curved proximally. Hindwing: cu-m fused with M to form a distinct anteriorly directed loop touching R posterior to costal space origin; A1 forked, A2 present, CuA distinctly bent towards A1, cu-a long, rarely attenuated or absent.

Male abdomen ( Fig. 5e–i ): length short, not extending past wing apices; tergite VI with two transverse rows of approximately 15–25 pores on anterolateral margin, pores do not extend to dorsum, rows meet prior to dorsum to form collective oval shape ( Fig. 5h [i–ii]); setae present among pores; central region flanked by pores lacks setae; ectoprocts posteriorly slightly elongated but do not extend past apex of sternite IX in lateral view, apices not globose; ventromedial lobes prominent, medially directed, majority of spines on ventral surface, sternite IX with prominent central patch of setae, ventrocaudal indentation posterior to setae patch in lateral view, indentation with conspicuously less setae than surrounding areas; pseudopenis longer than pseudopenal membrane; pseudopenal membrane triangular, tapering towards pseudopenis; hypomeres prominent 1/3 from midline to gonocoxites; basal apices of gonocoxites extend past hypomeres, median gonarcal lobe a thin elongated protrusion, ½ the length of pseudopenis, basal apex of mediuncus arrow-shaped, basally elongated, extending well past the basal apices of the gonocoxites.

Notes: The biology of Campanacella remains unknown. At rest the wings are held in a roof-like manner over the abdomen, unlike the wasp mimicking genera.

The colouration of C. hamiltonella ( Westwood, 1867) and C. radiata ( Navás, 1914b) corresponds well with C. javanica ( Westwood, 1852) . Both the overlapping distributions and similar morphology indicate that a possible synonymy between the and should be investigated.
