5.2.21.13. Scaphisoma vagenotatum PIC

Scaphisoma vagenotatum PIC, 1926 : 2. Lectotype ♀, MNHN; type locality: Mindanao, Dansalan. Lectotype designation: LÖBL 1972: 106.

Redescription: Length about 2.0 mm, width 1.40 mm. Head, pronotum, hypomera, femora and tibiae ochreous. Most of elytra, mesoventrite, metaventrite and sternites 1 to 3 reddish-brown, apical fourth of elytra, apical sternites, antennae and tarsi yellowish. Length/width ratio of antennomeres as: III 15/8: IV 45/7: V 64/8: VI 64/8: VII 66/12: VIII 50/9: IX 65/12: X 65/12. Pronotum almost evenly and very finely punctate. Hypomera smooth. Elytra with sutural striae starting about 0.25 mm posterior tip of scutellum, weakly converging apically, near bases indicated by puncture rows; lateral margin carinae hardly visible, lateral striae distinctly punctate; discal punctation fairly coarse, most puncture intervals about 1.5 to 2.5 times as large as puncture diameters. Mesanepisterna not microsculptured. Mesepimera about four times as long as wide, about as long as intervals to mesocoxae. Metaventrite weakly convex in middle, with punctation very fine and sparse, except for two shallow, coarsely punctate apicomedian impressions, fairly coarse and very dense antecoxal puncture rows and coarse punctures margining submesocoxal lines; microsculpture strigulate and distinct, absent from anterior surface of lateral areas. Submesocoxal areas about 0.03 mm, as sixth of intervals to metacoxae, submesocoxal lines subparallel. Metanepisterna narrowed anteriad, rounded near angles. Mesotibiae weakly curved. Abdomen with strigulate microsculpture, very finely punctate, except for dense, distinct punctures along basal margin of intercoxal process of sternite 1. Submetacoxal areas 0.05 mm, almost as fifth of intervals to apical margin of sternite 1, submetacoxal lines convex.

Distribution: Philippines: Mindanao.

Comments: The unique type has the apices of the elytra damaged, obviously by Anthrenus , and both antennomeres XI are broken off and missing. The specimen is similar to but cannot be associated with S. philippinense from which is differs by the lighter hypomera, not microsculptured mesanepisterna, elytra with narrower light apical areas with hardly visible lateral margin carinae in dorsal view.
