Sidonis guttata ( Sicard, 1912)

( Figs. 12–23 )

Aulis guttata Sicard 1912: 137 (original description); Korschefsky 1931: 95 (catalog); Blackwelder 1945: 443 (checklist). NeorhiZobius barrigai González 2013: 66 . Syn. nov.

Diagnosis. Sidonis guttata resembles S. biguttata sp. nov. by the number of spots on the elytra and shape of male genitalia, but differs in the size and shape of spots and size of penis guide. It resembles S. lineatosignata somewhat, but according to Mulsant’s description that species has spots distributed in a longitudinal line.

Redescription. Length 2.75–3.50 mm, width 2.25–3.08 mm. Male. Body slightly oval; with uniform, bristly, long, yellowish hairs; integument dark brown, punctation dense ( Fig. 12 ). Head, antennae and mouthparts yellow ( Fig. 13 ). Pronotum with two yellow lateral spots ( Fig. 14 ). Scutellar shield triangular, dark brown. Elytra with yellowish margin, extending throughout the length of elytra; each elytron with three rounded orange yellowish spots, one lateral, reaching margin or not; the second and third (anterior and posterior) in the same row, both equally distant from sutural margin; anterior one placed almost in middle of disc; posterior spot placed near the apex ( Figs. 12–15 ). Epipleuron yellowish brown, narrowing to apex ( Fig. 13 ). Meso- and metaventrite brownish. Legs yellowish with flattened femora; tibiae narrow, claws bifid. Abdomen with postcoxal lines moderately deep, extending along about 2/3 length of ventrite; first ventrites and middle region of the ventrites brownish ( Fig. 16 ). Genitalia with tegmen symmetrical, penis guide wide at base and acuminate at apex, 2/3 of the parameres length; parameres slightly enlarged, longer than tegmen, with bristles ( Figs. 17–18 ). Penis sclerotized, J-shaped, with acuminate recurved apex, penis capsule with developed inner arm ( Fig. 19 ).

Female. Similar to male. Genitalia with coxites longer than wide, sub-triangular; spermatheca with recurved cornu, highly developed ramus and sperm duct long ( Fig. 20 ).

Geographical distribution. Brazil, Argentina.

Type material. Photographs of the syntype were studied; it is deposited in the Senckenberg Deutsches Institut Entomologisches, Germany ( SDEI) with the following labels: " Brazil / Schaum", " Aulis / guttata / Sic. / type ", "Coll. Kraatz / Sicard det. " Syntypus " [pink label]. This specimen is here designated as lectotype ( Figs. 21–23 ).

The holotype of Neorhizobius barrigai contains the following labels: Pto. Bacetti/ 3 km. S. de Iguaz/ 30.VI.65 / col. H.G.C., Misiones/ Argentina, 17297/ colección/ J. E. Barriga/Stgo. Chile, “HOLOTYPE/ Neorhizobius / barrigai / González 2013.

Remarks. Sicard (1912) in the original description of Aulis guttata highlighted the color pattern, referred to the three spots on each elytron, and additionally mentioned that A. guttata and A. lineatosignata belong to the subgenus Sidonis.

González (2013) described a new species of Neorhizobius , N. barrigai , with morphological characters and genitalia identical to Sidonis guttata . Therefore, N. barrigai González, 2013 is synonymized here with S. guttata , expanding the distribution of this species to Argentina.
