DIAGNOSIS (
♀
): Mediumsized individuals (
2 mm
); body lightcolored, honey yellow, highly shining, with only very sparse semidecumbent pale hairs; foamy structures and cushions of hairs not developed, but few areas of dense pilosity occur; sculpture of head rough rugulose, almost corrugated, especially on postgena; strong keel running from OOL area down on temple and postgena, almost reaching malar area; occiput abruptly sloping down behind posterior ocelli; entire side of pronotum remarkably rugulose, epomium strongly developed, bladelike sharp; scutellar disc strongly subcircular; metapleuron remarkably smooth, mirrorlike shining and glabrous; median part of petiole with transverse scalelike node, with posterior margin sharply carinate; S2 produced ventrally, with dense tuft of hairs at meson.
DESCRIPTION (
♀
): HEAD. Head in dorsal view subhexagonal, slightly transverse, frons medially with sharp keel, antennal shelf rath er large, not completely margined posteriorly; temple behind eye remarkably short; occiput abruptly sloping down behind posterior ocelli; head in lateral view with antennal shelf distinctly protruding, level of torulus in middle of eye; eye remarkably large, distinctly higher than long, larger than half of head height, distinctly larger than malar space, posterior orbit of eye almost straight; ommatidia large, highly convex, raspberrylike; sculpture of head rough rugulose, almost corrugated, especially on postgena; strong keel running from OOL area down on temple and postgena, reaching almost malar area; OOL subequal to LOL; oral carina well developed; occipital flange rudimentary but steplike; head in frontal view with face slightly wider than higher, mandible bidentate, teeth subequal, sharply pointed; clypeus relatively well indicated by depressions in epistomal area; head in ventral view with hypostomal bridge present; palpi very short, palpal formula 3– 2; antenna 12segmented, with indistinct nondifferentiated multisegmented clava (6–7 segments), A12 subequal to A
11 in
size, clavomeres with narrow gaps; A1 robust, cylindrical, unarmed apically, but with rather sharp rim. MESOSOMA. Pronotum in dorsal view relatively well developed, pronotal shoulders not developed, entire side of pronotum remarkably rugulose, epomium strongly developed, bladelike sharp; mesoscutum slightly longer than wide, distinctly convex, parapsidal and admedial lines not developed; tegula well developed; anterior scutellar pit subcircular, relatively small and shallow, shorter than scutellar disc; scutellar disc remarkably subcircular, lateral keels not developed, sides sloping round into axillar depression; posterior margin of axilla perfectly rounded, axillar depression small, nonexcavate under axilla; mesopleuron distinctly flat, subrectangular, oblique submedian line fine; dorsellum well defined with sharps keels, middle keel bladelike; metapleuron remarkably smooth, mirrorlike shining and glabrous, with sharp keel on ventral margin; propodeum subquadrate, bunlike, median keel moderate or absent, plica not developed but sides of propodeum sharply carinate, surface of propodeum predominantly smooth, posterior margin of propodeum moderately arcuate, very sharp, propodeum in lateral view convex, not sloping, flattened dorsally; wings primarily developed but lost in all specimens examined; legs long and strong, coxae strong, hind coxa pearshaped, femora moderately clavate, tarsi only moderately compressed. METASOMA. Petiole highly modified, strongly necklike constricted anteriorly and posteriorly, median part with transverse scalelike node, posterior margin sharply carinate, petiole in lateral view high er than long, with deep horizontal cleft at meson; metasoma past petiole highly convex dorsally and ventrally, anterior margin of syntergite sloping roundly to petiole, ecarinate; S2 produced ventrally, with dense tuft of hairs at meson, specialized spot not visible.
RECOGNITION AND RELATIONSHIPS:
Neivapria
is recognized by the following peculiar character states: general shape of head (occiput, postgenal keel, sculpture), sculpture of metapleuron, shape of petiole, and tuft of hairs on S2.
Neivapria
resembles
Asolenopsia
in some cephalic character states; however it remains a rather isolated genus because of many peculiarities.
MALE: Unknown.
DISTRIBUTION: We examined two species from
Brazil
(including
paratype
of
N. penicillata
Borgmeier
).
BIOLOGY: Numerous females of
N. penicillata
were collected from columns of
Neivamyrmex minensis
(Borgmeier)
.
Borgmeier (1939)
assumed that
N. penicillata
is primarily (hereditary) apterous; however, the tegula is normally developed and stumps of wings indicate secondary loss of wings due to lytic alectomy.
