status

subsp. nov.

Dysiatus melas adami , ssp. nov.

Type and paratype material. Holotype ♂, Tahuna , Sangihe Island , North Sulawesi Province, Indonesia, June 2001, unknown collector ( Fig. 1 View FIGURE 1 A–10A) (presently stored in Paolo Missori’s collection) [pinned through right elytron; genitalia dissected and glued on transparent plastic cardboard]. 1 Paratype ♂ Talaud Island 11/2013, 1 Paratype ♂ Sangihe Island 08/2016, 1 Paratype ♂ Talaud Island 03/2016 ; Holotype ♀ Sangihe 08/2016 ( Fig. 11A View FIGURE 11 ). 1 Paratype ♀ Sangihe 08/1980, 1 Paratype ♀ Sangihe 06/2013, 3 Paratype ♀ Talaud 11/2013, 1 Paratype ♀ Talaud 03/2016 .

Description. Color. Dark reddish-brown.

Length. Total, including mandibles: 90.88 mm.

Head. Large, covered with short golden setae; distance between eyes: 3.24 mm. A wide and deep impression from vertex to between the antennal tubercles. Clypeus in dorsal view, triangular; coarsely punctate with long, sparse, gold setae.

Mandible. Strong, robust, elongate, and coarsely punctate with microreticulations.

Antenna. Reaching backwards about 2/3 of elytra length. The antennal scape attaining pronotum, gradually and slightly enlarged apically, covered with distinct, irregularly spaced shallow punctures proximally, deeper on the distal end. Several spiny tubercles lie on the anterior and posterior half of the scape. The first and second antennomere elongated, reaching the back corner of the pronotum. Pronotum. Overall rectangular, with anterior and posterior border basically flat. Surface coarsely, deeply punctate, covered with some short golden pubescence. Thick golden bristles are present on the front margin to the junction with the head. As wide at the base as the elytra, dentate along the lateral margin with small, not-sharpened spinules. Two thin, scarcely visible and parallel linear tubercles lie on the half anterior.

Scutellum . Large, brown, bordered with a linear impression, transverse, minutely punctured.

Prosternal apophysis. Strong and broad on the base with smooth apex and golden setae on the external edges. Surface reticulate.

Elytron. Surface coarsely, deeply punctate, covered with dense and short golden pubescence, with flanged lateral margin. Width at mid-length: 33.04 mm. Four slightly raised costae from base to near apex, with few intercostal bridges on the distal side. Tips of elytra rounded, with a small ridge at the apex of each elytral suture.

Legs. Forelegs longer than mid-legs, thin and covered along the internal margin with short dense spinules. Hind legs smoother, rugosely punctate on the lateral margin with short dense spinules on the medial surface.

Abdomen. Very sparsely pubescent.

Diagnosis. A pair of Dysiatus melas ( Pascoe, 1869) from Sulawesi of the same size as the new subspecies are shown to compare the differences between the subspecies ( Fig. 1 View FIGURE 1 B–11B). The new subspecies Dysiatus melas adami ssp. nov. resembles Dysiatus melas ( Pascoe, 1869) described from Sulawesi Island but differs in having more elongated forelegs covered along the internal margin with short dense spinules and a longer scape and antennomeres. The elytra are covered by dense, short, golden pubescence that is much less conspicuous in Dysiatus melas ( Pascoe, 1869) . The median lobe and tegmen of Dysiatus melas adami ssp. nov. show distinctive characters from Dysiatus melas ( Pascoe, 1869) . The comparison of the Dysiatus melas female confirms in Dysiatus melas adami ssp. nov. has more elongated forelegs as well the longer scape and antennomeres.

Etymology. This subspecies is named for the beloved child of both authors, who lives with us.
