Rhogadopsis Brethes, 1913

Taxonomic History / Nomenclature
Rhogadopsis Brethes, 1913: 44-45. Type species: Rhogadopsis miniacea Brethes, 1913 (monobasic).

Type locality of type species: Argentina, Buenos Aires; lectotype female in Buenos Aires, designated by Wharton (1987).

Treated as a synonym of Opius s. l. by De Santis (1967); proposed by Wharton (1987) as a senior synonym of Opius (Lissosema Fischer, 1972), belonging to the tucumanus species group of Fischer (1972). More recently elevated to generic rank by Li et al. (2013).

Diagnosis and Relationships
Rhogadopsis and Lissosema were characterized in Fischer’s (1972) classification of subgenera of Opius s.l. on the basis of the absence of a mesoscutal midpit (Fig. 2), presence of a precoxal sulcus (Fig. 6), an exposed labrum (Fig. 1), fore wing m-cu postfurcal (Figs 4, 5), absence of sculpture on the top of the head and on metasomal terga 2 and 3, a sculptured propodeum (Figs 3, 7), and the posterior margin of the mesopleuron without crenulations dorsally (Fig. 6). Li et al. (2013), on the other hand, emphasized characters not used by Fischer (1972) when they redefined Rhogadopsis and elevated it to generic rank. Li et al. (2013) continued to treat Lissosema as a synonym of Rhogadopsis while defining Rhogadopsis on the basis of the presence of a median longitudinal carina on the propodeum (Fig. 7) and fore wing venation in which 1m-cu and 2M do not form a distinct angle but more gradually merge with one another (Figs 4, 5).

The type species of Rhogadopsis additionally has the dorsal tooth of the mandible much larger than the tiny ventral tooth (Fig. 1); the mandible with a strong carina forming the entire ventral margin, but lacking a basal tooth or lobe ventrally; a very slightly protruding clypeus (Fig. 1); occipital and hypostomal carinae very widely separated at the base of the mandible, with hypostomal carina distinctly protruding as a flange beneath the mandible; a deep, narrow malar sulcus (Fig. 1); notauli short, transverse, deep and crenulate; precoxal sulcus about as in Fig. 6: short, broad, crenulate ventrally and somewhat more rugose dorsally; posterior margin of mesopleuron crenulate ventrally but smooth dorsally (Fig. 6); metapleuron smooth medially but with crenulate anterior margin and foveolate ventral, dorsal, and posterior margins; propodeum reticulate/rugose as in Figs 3 and 7, with the median longitudinal carina present but not easily differentiated from surrounded sculpture; T1 with laterope deep and round, dorsope absent but dorsal carinae well developed and extending full length of T1.

Figs 1-5 are of the lectotype of Rhogadopsis miniacea. Figs. 6 and 7 are of a specimen compared with the type that has very similar mesopleuron, metapleuron, and propodeum, but which lacks the distinctive fore wing venation.

This page was assembled by Bob Wharton and Danielle Restuccia. It is part of a review of the genera of World Opiinae, conducted at Texas A&M University. We are particularly grateful to Xanthe Shirley, Andrew Ly, Patricia Mullins, Trent Hawkins, Lauren Ward, Cheryl Hyde, Karl Roeder, and Andrea Walker, who did nearly all of the imaging (together with Danielle) for this project. Matt Yoder and Istvan Miko provided guidance on databasing issues associated with our use of mx and HAO respectively. This project would not have been possible without the kindness of many curators at museums throughout the world who gave generously of their time to Bob Wharton and his students.
