T y p e m a t e r i a l e x a m i n e d: Holotype: ″ La Réunion, Rempart de Bélouve, 26.i.1955, // Gabrius rabigoides, J. Jarrige det., Holotype, [white oblong label handwritten], Institut Scientifique Madagascar ″ (MNHN). Paratype. [same label data as in holotype).
R e d e s c r i p t i o n: Body length 4.6 mm, length of fore body (to end of elytra) 2.2 mm. Head and abdomen black, pronotum and elytra black-brown, maxillary and labial palpi black-brown, antennomeres 1-2 and base of antennomere 3 yellow-brown, remaining antennomeres black-brown, legs yellow-brown.
Head longer than wide (ratio 19: 15), slightly narrowed posteriorly, posterior angles markedly rounded. Between eyes 4 punctures, distance between medial punctures about 4 times as large as distance between medial and lateral puncture, medial punctures slightly shifted anteriad, temporal area with scattered punctures. Eyes small, shorter than temples (ratio 5: 9). Surface with very fine irregular microsculpture.
Antennae reaching posterior fourth of pronotum when reclined, antennomere 1 more than twice longer than antennomere 11, antennomeres 2-3 equal in length.
Pronotum highly convex, longer than wide (ratio 19: 15), distinctly narrowed anteriorly. Each dorsal row with 6 approximately equidistant punctures, each sublateral row with 2 punctures, puncture 2 slightly shifted to the lateral margin. Microsculpture similar to that of head.
Scutellum very finely and coarsely punctured. Diameter of punctures as large as eyefacets, separated larger than 1 puncture diameter in transverse direction. Surface with fine microsculpture consisting of transverse waves.
Elytra slightly wider than long (ratio 23: 21), slightly widened posteriorly. Punctation coarse and dense, diameter of punctures larger than eye-facets, separated by one and half puncture diameter. Surface lacks microsculpture; setation longer and grey
Legs. Metatibia longer than metatarsus (ratio 14: 11), metatarsomere 1 slightly shorter than metatarsomere 5.
Abdomen wide, gradually narrowed posteriorly beginning with visible tergite III. Punctation at base of all tergites finer and sparser than that on elytra, becoming finer and sparser towards posterior margin of each tergite. Surface lacks microsculpture; setation similar to that on elytra.
C o m p a r a t i v e n o t e s G. rabigoides is quite similar to G. macer in many cha-
racters, but differs as follows: shorter eyes, slightly shorter antennae and by the different shape of the aedeagus.
D i s t r i b u t i o n: Réunion ( HERMAN 2001).
