barberi Blake, 1943b: 440 (type locality: Gov. Finca, Villalba, Puerto Rico; holotype, male, USNM); as Hadropoda. Scherer,

Redescription. Body length 1.79–1.96 mm, width 0.94–1.15 mm. Head, except mouthparts, antenna, except antennomere 5 and 6 in males and 5 in females, pronotum, base of elytron, and metafemur dark brown to blackish. In male scutellum and apical part of elytra yellowish. Venter dark brown, except yellowish last ventrite. Antennomeres 1 and 2 dark. In males antennomeres 5 and 6 white. In females antennomere 5 white. Sparse golden yellow setae scattered evenly across pronotum. Golden yellow setae form distinct pattern on elytra with wide band in the posterior half of elytra having dark spot near suture. Elytral apex with light setae. In addition, thin band of white setae situated at base of elytra. Some thinner and darker setae also present. Hind femora with light and dark setae forming a pattern in which dark setae make a spot on top of femur. Supraorbital pore distinct among other setiferous pores on vertex. Antennal calli slightly raised above surrounding surfaces, smooth. Supracallinal sulcus absent, however there is a shallow impression in its place. Similar impression in place of suprafrontal sulcus. Midfrontal sulcus wider basally than towards top of antennal calli, more so in female. Frontal and anterofrontal ridges slightly raised, with uneven surface. Anterofrontal ridge in middle abruptly extends towards labrum. Proportions of antennomere lengths in male: 12:6:8:7:7:7:7:9:9:9:11; in female: 12:7:9:6:7:7:8:7:8:9:12. Pronotum rectangular, 1.5 times wider than long. Punctures as dense on pronotal protuberances as between them. Scutellum covered with setae dens- er than elytra. Scutellar row of punctures very short, consisting of one or two punctures. Interspaces convex, less so in between puncture rows three and four. Proportions of mesotarsomere length in male as follows: 10:8:11:22. Median lobe simple, slightly and evenly curved in lateral view; in ventral view, with lateral sides almost parallel, apex subtriangular, without denticle. Venter apically flatter than basally. Dorsal flap comes close to apex.

Remarks. Menudos barberi can be differentiated from M. chamorrae by the presence of the stripe of yellowish setae at the base of elytra (stripe is absent in M. chamorrae); unicolorous female elytra (it is dark at the base and yellowish at the apex in M. chamorrae); midfornal sulcus being wider at the base than deeper between antennal calli (it is parallel sided in M. chamorrae); median lobe of the aedeagus evenly convex in lateral view with the dorsal flap coming close to the tip of the median lobe (in M. chamorrae, this flap comes at a distance to the tip of the lobe).

Habitat. Habitat of M. barberi is not known. Blake (1943b) mentioned the third specimen collected by Oakley at the Principi Finca, Adjuntas on Areca catechu L. (Arecaceae). However, this specimen could not be located in the USNM collection, hence we are unable to confirm its conspecificity.

Type material. Holotype, male, with labels as follows: 1) Host unknown, Ins. Gov. Finca, Villalba, Puerto Rico, coll. 18 June, 34. R. G. Oakley; 2) sl #5658; 3) Type No 5616, USNM; 4) Hadropoda barberi Blake type (USNM). Paratype female, with the same label and on the same pin as holotype (USNM).
