Redescription. Body length 1.72–2.27 mm, width 0.91–1.14 mm. Head, except mouthparts, antenna, except antennomere five in males and five and six in females, pronotum, base of elytron, and metafemur dark brown to blackish. In female scutellum and apical part of elytra yellowish. Venter dark brown, except yellowish last ventrite. Antennomeres 1 and 2 dark. In males antennomere 5 white. In females antennomeres 5 and 6 white. Sparse golden yellow setae positioned laterally at base of pronotum. Golden yellow pubescence forms distinct pattern on elytra with wide band in the posterior half of elytra having dark spot near suture. Elytral apex with light setae. Some thinner and dark- er setae also present. Hind femora with light and dark setae forming a pattern in which dark setae make transverse band across 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 parallel sided. Frontal and anterofrontal ridges slightly raised, smooth.Anterofrontal ridge in middle abruptly extends towards labrum. Proportions of antennomere lengths in male: 12:4:6:5:5:5:7:7:7:6:9; in female: 12:6:5:5:5:6:6:6:6:7:9. Pronotum rectangular, 1.47 wider than long. Punctures as dense on pronotal protuberances as between them. Scutellum covered with setae denser than those on elytra. Scutellar row of punctures very short, consisting of one or two punctures. Elytral punctures on rows 2 and 3 placed close to each other. Interspaces convex, less so in between puncture rows 3 and 4. Proportions of mesotarsomere length in male as follows: 10:8:9:22. Median lobe simple, slightly curved in lateral view with more abrupt curvature near middle; in ventral view, with lateral sides almost parallel, apex subtriangular without denticle. Venter apically flatter than basally. In female genitalia, posterior part of sternite eight sclerotized along its entire margin. Tignum with rounded posterior margin, widely sclerotized along entire posterior margin, bearing many moderately long setae. Vaginal palpi elongate, anteriorly and along middle strongly sclerotized and merged anteriorly for more than half of their length, each with about eight setae at apex, with posterior sclerotization shorter than anterior. Spermatheca curved, with receptacle and pump not differentiated from each other (pump about as wide as receptacle). Apex of pump with flattened projection. Spermathecal duct long, forming “S” coils.

Remarks. Menudos chamorrae can be differentiated from M. barberi by the absence of stripe of yellowish setae at the base of elytron (stripe of yellowish hair present at the base of elytra in M. barberi ); yellow color of the posterior half of the elytron in females (elytron is unicolorous in female of M. barberi ); in males the posterior half of the elytron is light in color in M. barberi , while it is dark in M. chamorrae ; parallel sided midfrontal sulcus (midfrontal sulcus is wider at the base then deeper between antennal calli in M. barberi ); median lobe of the aedeagus more abruptly curved at base in lateral view with the dorsal flap coming at a distance to the tip of the lobe (in M. barberi median lobe slightly and evenly curved in lateral view and dorsal flap comes close to the tip of the median lobe).

Habitat. Menudos chamorrae was collected by sweeping at the mid elevation forest road on Toro Negro. It is unknown if it is associated with moss cushions or not. Tree trunks on the side of the road where the specimens were collected had some moss cover.

Type material. Holotype, male, with labels as follows: 1) Puerto Rico: Toro Negro , 18°11.850’N, 66°29.533’W, 904 m, 20.VI.2008, leg. M. L. Chamorro ( USNM) GoogleMaps . Paratype female, with the same label as holotype ( USNM) .
