Type species

Mimofulvius pentatomus Schmitz, 1978 View in CoL (original designation).

Diagnosis

In addition to the characters presented by Schmitz (1978) and Yeshwanth et al. (2016) for defining Mimofulvius , this genus can be distinguished from other cylapine genera by having the rudimentary stridulatory device (exocorium edge-hind femur, cf. Figs 8, 12–13 View Figs 6–13 ) and the endosoma with lobal sclerites ( Figs 4 View Figs 3–5 , 33 View Figs 28–34 ).

Redescription

Macropterous; body elongate to elongate-oval ( Figs 1–2 View Figs 1–2 , 6 View Figs 6–13 , 14–16 View Figs 14–17 , 24–27 View Figs 24–27 ). Dorsum shiny, covered with sparse or dense, simple setae ( Figs 6–9 View Figs 6–13 ).

HEAD. Subhorizontal ( Figs 1–2 View Figs 1–2 , 6–7 View Figs 6–13 , 14–16 View Figs 14–17 , 18 View Figs 18–23 , 24–27 View Figs 24–27 ), rugose, covered with long, dense, semirecumbent setae ( Figs 1–2 View Figs 1–2 , 6–7 View Figs 6–13 , 18 View Figs 18–23 ); clypeal base situated above ventral margin of eye ( Fig. 18 View Figs 18–23 ); mandibular plate without sulcus posteriorly ( Fig. 18 View Figs 18–23 ); antennal insertion contiguous with sulcus between maxillary and mandibular plates ( Figs 7 View Figs 6–13 , 18 View Figs 18–23 ); eyes contiguous with pronotal collar, relatively large, reniform in lateral view ( Figs 7 View Figs 6–13 , 18 View Figs 18–23 ); antenna short, about ⅔ times as long as total body length; antennal segment I short, weakly surpassing apex of clypeus, cylindrical, weakly narrowed basally, covered with sparse, thick, erect and semirecumbent setae; segment II weakly broadened toward apex, covered with dense, erect and semirecumbent setae; segments III and IV as thick as segment II, covered with setae similar to those present on segment II; segment IV subdivided medially, forming pseudo-5-segmented ( Figs 1 View Figs 1–2 , 6 View Figs 6–13 , 14–17 View Figs 14–17 , 25, 27 View Figs 24–27 ); labial segment I subdivided medially; segment II subdivided subapically ( Fig. 7 View Figs 6–13 ).

THORAX. Pronotum. Pronotal collar relatively broad, approximately as wide as antennal segment II diameter; pronotal calli from narrow, restricted to medial part of anterior part of pronotum to broad, reaching pronotal lateral margins ( Figs 1–2 View Figs 1–2 , 6 View Figs 6–13 , 14–16 View Figs 14–17 ); dorsal surface of pronotum shiny, covered with sparse, semirecumbent setae ( Figs 6 View Figs 6–13 , 18 View Figs 18–23 ). Mesoscutum and scutellum. Covered with sparse, erect or semirecumbent setae; scutellum flat ( Figs 1–2 View Figs 1–2 ). Thoracic pleura. Covered with sparse, short, semirecumbent setae ( Figs 7, 9 View Figs 6–13 , 18–19 View Figs 18–23 ); metathoracic scent efferent system with narrow evaporative area and ovoid auricula, occupying ventral and posterior margins; peritreme flat, relatively broad ( Figs 9 View Figs 6–13 , 19 View Figs 18–23 ). Hemelytron. Shiny, covered with sparse or dense, simple setae ( Figs 1–2 View Figs 1–2 , 7–8 View Figs 6–13 ); exocorium with notched edge that may represent stridulitrum, or stridulatory device ( Figs 8 View Figs 6–13 , 20 View Figs 18–23 ). Legs. Short; covered with sort, semirecumbent and recumbent setae ( Figs 1–2 View Figs 1–2 , 24–27 View Figs 24–27 ); metafemur with short carina, probably plectrum of stridulatory mechanism ( Figs 12–13 View Figs 6–13 , 21 View Figs 18–23 ); pretarsal claw with tiny, subapical tooth ( Fig. 10 View Figs 6–13 ).

ABDOMEN. Covered with dense, reclining and semirecumbent setae ( Fig. 7 View Figs 6–13 ).

MALE GENITALIA. Genital capsule with dorsal wall long, weakly shorter than ventral wall, genital opening is terminal in orientation ( Figs 7, 11 View Figs 6–13 , 28 View Figs 28–34 ). Left and right paramere curved; paramere body covered with relatively dense setae dorsally ( Figs 3, 5 View Figs 3–5 , 29–32 View Figs 28–34 ). Left paramere. Apical process elongated, inner surface with small swelling basally ( Figs 3 View Figs 3–5 , 29–30 View Figs 28–34 ). Aedeagus. Seminal duct long and thin, sclerotized part of seminal duct expanded; endosoma membranous, with two long lobal-sclerites and with ovoid, large, membranous lobe basally embraced by expanded sclerotized part of seminal duct ( Figs 4 View Figs 3–5 , 33 View Figs 28–34 ).

FEMALE GENITALIA. As described and depicted by Yeshwanth et al. (2016: fig. 30).

Remarks

The present study adds the possession of a (presumed) stridulatory device (a set of a notched margin of the forewing and a metafemoral plectrum or keel) to the diagnostic characters for Mimofulvius ( Figs 8, 13 View Figs 6–13 , 20–21 View Figs 18–23 ). As stated by Yasunaga et al. (2019) and Tamada et al. (2020), many epigeic plant bug species of the tribe Hallodapini Van Duzee, 1916 (Phylinae) have a similar stridulatory mechanism which is used for intraspecific communication. However, the actual function of the Mimofulvius stridulatory device requires further verification.
