HOLOTYPE WORKER. TL 1.8, HL 0.44, HW 0.39, CI 89, ML 0.17, MI 38, SL 0.21, SI 54 PW 0.26, AL 0.47. Characters of abdera-comp ex. Right mandible with a spiniform preapical tooth; left mandible with a spiniform preapical tooth proximally and a minute distal preapical denticle. Cephalic dorsum posterior of clypeal margin with rows of spoonshaped hairs on anterior two thirds; upper scrobe margin with spoon-shaped hairs. Cephalic dorsum with a transverse row of 4 erect, short clavate hairs near occipital margin. Pronotal humeral hair absent; mesonotum without standing hairs. Dorsum of alitrunk with short spatulate ground-pilosity. In profile, promesonotal dorsum very shallowly convex; propodeal dorsum more or less flat anteriorly, sloping posteriorly to the declivity and rounding into the sides. Propodeal tooth a small denticle incorporated in the very narrow lamella; in profile, width of lamella approximately the width of eye. Ventral spongiform tissue well developed and conspicuous on petiole and postpetiole. Base of first gastral tergite with a continuous row of well developed basal costulae. Color dull yellow to pale brown.
PARATYPE WORKERS. TL 1.8, HL 0.42 - 0.44, HW 0.38 - 0.40, CI 91 - 93, ML 0.16 - 0.17, MI 39 - 41, SL 0.20 - 0.22, SI 50 - 57, PW 0.24 - 0.26, AL 0.45 - 0.46 (3 measured). As holotype.
Holotype worker, Madagascar: Fotodriana, CapMasoala, 25 m., 15 ° 41 ' 49 " S, 5 O ° 16 ' 13 " E, 27. xi. 1993, rainforest, Winkler app. 160.13981 w (G. D. Alpert) (MCZ).
Paratypes. 1 worker with same data as holotype but coded 160.13982 w; 2 workers (one with gaster missing) with same data as holotype but coded 160.3635 w, 160.3636 w and labeled lowland rainforest (Alpert et al.) (BMNH, SAM).
NON-PARATYPIC MATERIAL EXAMINED. Madagascar: F. C. Andriantanteiy 530 m. (H. J. Ratsirarson).
Measurements of non-paratypic material extends the range shown by the type-series: HL 0.45 - 0.48, HW 0.43 - 0.45, CI 95 - 96, ML 0.17 - 0.19, MI 38 - 40, SL 0.23 - 0.25, SI 53 - 56 (3 measured).
Within the arnoldi-group with 6 antennal segments, charino is separated from all other members by having:
1 Cephalic dorsum posterior of clypeal margin with rows of spoon-shaped hairs on anterior
two thirds.
2 Pronotal humeri and mesonotum without erect hairs.
3 Base of first gastral tergite with a continuous row of well developed basal costulae.
4 Lamella of propodeal declivity very narrow in profile, approximately equal to width of eye.
