Paracaraptera
n.gen.
Type
species:
Paracaraptera schuhiana
n. sp.
Diagnosis.
Small and apterous, its habitus resembling that of
Acaraptera
species
described from
New Zealand
,
Samoa
, and the
Fiji Islands
; however, the sculpured dorsal structures and the shape of head are different from
Acaraptera
Usinger & Matsuda 1959
. It differs also from
Rugicarventus
n.gen.
by the short antennae, the dilated postocular lobes, the laterally produced anterolateral angles of the pronotum, and the shape and sculpture of the thorax and abdomen.
Description.
Apterous, elongate oval; colouration yellowish brown with darker patches on thorax and abdomen.
Head:
Wider than long, genae projecting over clypeus reaching ½ of antennal segment I; antenniferous lobes triangular; antennae short about as long as width of head, segment I longest and thickest, II and III shorter and thinner, IV fusiform; eyes granulate inserted in head; postocular lobes dilated and dentate; rostrum shorter than head.
Pronotum:
Strongly transverse, collar very thin and smooth, anterior margin carinate and straight, highest at middle; disk with a median carina and lateral callosities delimited by deep grooves; anterolateral angles granulate and triangularly projecting laterally at a lower level than disk; posterior margin convex and deeply sulcate separating pro- from mesonotum; all thoracic segments fused to each other and to mtgI+II forming a continuous medially sulcate ridge, although their fusion lines are marked by distinct grooves.
Mesonotum:
Produced posteriorly at middle with a sulcate longitudinal ridge,this separated from ovate lateral callosities by deep grooves.
Metanotum:
Consisting of a bicarinate median ridge and larger and smaller ovate lateral callosities; on mtgI the two carinae are bent laterally leaving a deep pit at middle; mtg II is transversely carinate but this interrupted at middle by a depression.

Abdomen:
Median longitudinal elevation carinate at base, then flat and widening toward abdominal scent gland and again carinate on mtg V and VI; apodemal impressions delimited by polygonal carinae; deltg I+II fused and extending to pronotum; deltg III–VII separated by sutures with carinate lateral margins, disk with 2 apodemal impressions; all spiracles lateral and visible from above.
Legs:
Femora and tibiae slender and cylindrical, claws with thin pseudopulvilli.
