Strongylaspis antonkozlovi Galileo and Santos-Silva , sp. nov.

( Fig. 1–7 View Figures 1–12 )

Description. Male ( Fig. 1–6 View Figures 1–12 ). Integument mostly dark brown and opaque; mouthparts dark reddishbrown; antennae and elytra gradually, slightly dark reddish brown toward apex; mesocoxae reddish brown; metacoxae partially dark reddish brown; metafemora partially dark reddish brown on basal half; abdominal ventrites dark reddish brown with irregular dark brown areas, except glossy dark brown distal area of ventrites I–IV.

Head. Dorsal surface concave between clypeus and posterior edge of upper eye lobes; finely, densely rugose-punctate between clypeus and posterior edge of upper eye lobes, finely, densely rugose on remaining surface; with abundant, decumbent golden setae not obscuring integument, except nearly glabrous transverse central area between posterior edge of upper eye lobes. Area behind eyes finely, densely rugose; with abundant golden setae close to eye, gradually sparser toward ventral side, slightly sparser on remaining surface behind upper eye lobe, gradually sparser toward ventral side. Antennal tubercles moderately coarsely, confluently punctate basally, gradually finely punctate toward apex; with golden setae not obscuring integument, short and denser frontally close to gena, nearly glabrous at apex. Median groove distinct from clypeus to area behind eyes. Postclypeus large, slightly concave, longitudinally sulcate centrally; finely, densely rugose-punctate except smooth sides; with moderately long golden setae on rugose-punctate area, glabrous on smooth areas. Labrum coplanar with clypeus on basal 2/3, inclined on distal third; with long, abundant golden setae directed forward and short fringe of golden setae distally. Genae finely, moderately sparsely punctate toward dorsal side, finely rugose-punctate toward ventral side; with short, sparse golden setae (shorter, sparser toward apex). Gulamentum moderately coarsely rugose, slightly less so close to prothorax; with long, erect, moderately abundant golden setae. Distance between upper eye lobes 0.50 times length of scape; in frontal view, distance between lower eye lobes 1.30 times length of scape; in ventral view, distance between lower eye lobes 0.85 times length of scape. Antennae (only holotype measured) 1.35 times elytral length, slightly surpassing elytral apex. Scape gradually widened toward apex; finely, densely rugose-punctate except smooth, narrow distal area; with decumbent golden setae on rugose-punctate area, glabrous on smooth area. Antennomere III distinctly thicker than remaining antennomeres; somewhat finely rugose-punctate except smooth, narrow distal area; with decumbent golden setae (ventrally interspersed with sparse erect golden setae), except glabrous smooth area. Antennomere IV with sculpturing and setae as on III. Antennomeres V with sculpturing as on IV except longitudinal carina on distal 2/3 of outer side, and striae on distal third of outer side; with short, decumbent, sparse golden setae. Antennomeres VI–VII with sculpturing as on V except longitudinal carina from base to apex of outer side, and striae nearly reaching base of ventral side; with short, decumbent, sparse golden setae. Antennomeres VIII–XI entirely striate; nearly glabrous; glabrous except short golden setae at apex. Antennal formula (ratio) based on length antennomere III: scape = 0.71; pedicel = 0.22; IV = 0.62; V = 0.61; VI = 0.54; VII = 0.54; VIII = 0.49; IX = 0.47; X = 0.46; XI = 0.71.

Thorax. Prothorax transverse, 1.7 times wider than long (excluding lateral spines); anterolateral angles flattened (rectangular), projected forward; lateral margins strongly divergent from base to lateral spine, slightly convergent from lateral spine to about middle, distinctly convergent toward anterolateral angle; finely crenulate between lateral spines and anterolateral angles; lateral spines moderately long, placed at basal quarter, slightly inclined backward. Pronotum with five gibbosities: one large, moderately oblique, subelliptical on each side of base; one large, transverse, subelliptical, longitudinally sulcate, placed centrally; one moderately large, more evident, glossy, irregular, distinctly contrasting with remaining surface of pronotum, on each side on distal third. Area between glossy pronotal gibbosities with moderately deep, circular depression. Pronotal surface opaque, granulate-punctate, except glossy gibbosities coarsely, partially confluently punctate; with decumbent, moderately abundant golden setae not obscuring integument, sparser toward lateral spines, nearly smooth on tip of glossy gibbosities. Hypomeron opaque, very slightly rugose; with decumbent, sparse golden setae. Prosternum minutely, abundantly punctate between finely scabrous surfaces; with golden decumbent golden setae not obscuring integument, interspersed with moderately long, erect golden setae. Prosternal process longitudinally sulcate; with erect and decumbent golden setae. Apex of mesoventral process deeply emarginate centrally. Metanepisternum minutely, densely punctate; with moderately long, decumbent golden setae not obscuring integument. Metaventrite minutely, densely punctate; central area with large, triangular area slightly depressed; nearly glabrous on wide inversed V-shaped area, starting at metaventral process, not reaching metanatepisternal suture; with dense fringe of golden setae close to sides of triangular depression; with moderately abundant, long, erect golden setae inside triangular depression. Scutellum not strongly tumid, longitudinally depressed basally; with small, moderately abundant asperities; with short, sparse, decumbent golden setae, denser on margins. Elytra. Parallelsided on basal 2/3, then slightly convergent toward rounded apex; sutural angle slightly projected; finely scabrous on basal fifth, nearly smooth toward apex; with short, abundant golden setae partially obscuring integument. Legs. Profemora scabrous, with nearly acute tubercles on distal half of ventral side; with short, decumbent golden setae not obscuring integument, interspersed with long, sub-erect golden setae ventrally. Meso- and metafemora finely rugose-punctate; with sparse nearly acute tubercles on distal half of ventral side; with decumbent golden setae not obscuring integument, interspersed with long, erect golden setae ventrally. Protibiae distinctly widened toward apex; scabrous, with short nearly acute tubercles on ventral side. Meso- and metatibiae moderately widened toward apex, finely scabrous. Metatarsomere I slightly longer than II–III combined.

Abdomen. Ventrites opaque, densely, minutely punctate except smooth, glossy distal area of ventrites I–IV. Distal third of ventrite V distinctly inclined centrally; distal margin widely notched centrally. Surface of ventrites with short, decumbent golden setae not obscuring integument, except glabrous smooth area of ventrites I–IV.

Female ( Fig. 7 View Figures 1–12 ). Differs from male especially by the more slender and longer, shorter antennae (0.95 times elytral length, reaching about base of distal third of elytra), abdominal ventrite V flat throughout, with its apex deeply emarginate centrally. The general color of the paratype female is more reddish than in the males.

Dimensions (mm) (holotype male/ paratype males/ paratype female). Total length, 29.70/27.00– 31.10/32.20; prothoracic length, 5.05/4.70–5.05/4.80; basal prothoracic width, 6.30/5.55–6.00/6.25; distal prothoracic width, 6.75/5.70–6.20/5.70; maximum prothoracic width (between apices of lateral spines), 9.75/8.20–9.10/8.70; humeral width, 10.65/8.55–10.20/10.15; elytral length, 22.05/20.50–23.35/25.00.

Type material. Holotype male from HONDURAS, Cortés: Cusuco National Park , 15°29 ʹ 32 ʺ N / 88°12 ʹ 38 ʺ W; 1520 m), 22–28.VI.2014, V. Sinyaev and M. Marquéz col. ( MZSP) GoogleMaps . Paratypes, 2 males ( AKPC) , 1 female ( MZSP) same data as holotype .

Etymology. The new species is named after Anton Olegovich Kozlov, who sent the specimens for study, and donated the holotype and a paratype to the MZSP collection.

Remarks. Strongylaspis antonkozlovi sp. nov. is similar to S. bullata Bates, 1872 ( Fig. 9–12 View Figures 1–12 ), but differs as follows: basal antennal segments with longer and distinctly more abundant setae in both sexes ( Fig.1, 7 View Figures 1–12 ); pronotal gibbosities on distal half distinctly punctate ( Fig. 6 View Figures 1–12 ); prosternal process slightly narrower than diameter of the antennomere III ( Fig. 2 View Figures 1–12 ); mesoventral process slightly wider than diameter of the antennomere III ( Fig. 2 View Figures 1–12 ); scutellum with smaller and more abundant asperities ( Fig. 5 View Figures 1–12 ); femoral setae more abundant and longer ( Fig. 1 View Figures 1–12 ); apex of abdominal ventrite widely notched centrally in male ( Fig. 2 View Figures 1–12 ). In S. bullata , the basal antennal segments have shorter and distinctly sparser setae in both sexes ( Fig. 11 View Figures 1–12 ), pronotal gibbosity on distal half smooth ( Fig. 10 View Figures 1–12 ); prosternal process and mesoventral process noticeably wider than diameter of the antennomere III ( Fig. 12 View Figures 1–12 ); scutellum with larger and sparser asperities ( Fig. 8 View Figures 1–12 ), femoral setae shorter and distinctly sparser ( Fig. 11 View Figures 1–12 ), and apex of abdominal ventrite truncate in male ( Fig. 12 View Figures 1–12 ). Strongylaspis antonkozlovi differs from S. championi Bates, 1884 , especially by the elytra distinctly pubescent in both sexes (glabrous in S. championi ).
