Carvalhoma taplini Slater & Gross, 1977: 137 .

Diagnosis

Separated from all other species in the genus by the following characters: head and pronotum matte and shagreened, hemelytron shiny, with distinct punctures ( Fig. 1G ); body large and ovate, total length of female 2.1–2.3, ca 3.6–3.8× longer than pronotum; antennal segment I ca 1.2–1.4× as long as vertex width; pronotum laterally with dense wrinkles and setae ( Fig. 5G ).

Material examined

Holotype

AUSTRALIA: ♀, South Australia, 1 km NW of Monash , 34.26742 ° S, 140.57012 ° E, 17 May 1970, I.C. Taplin (00043321) ( ANIC).

Paratype

AUSTRALIA: 1 ♀, same collection data as holotype (00043322) ( ANIC).

Description

Male

Unknown

Female

BODY LENGTH. 2.1–2.3.

COLOURATION ( Fig. 1G ). Dark brown, mostly with reddish tinge, head anteriorly pale brown to yellow, antenna, labial segments I–III, fore- and middle coxa, tibiae and tarsi yellow, hind coxa brown or yellow, ventral side of abdomen pale brown or brown.

SURFACE AND VESTITURE. Body mostly matte and shagreened, hemelytron moderately shiny and distinctly punctate ( Figs 1 , 5J ), pronotum laterally wrinkled ( Fig. 5A ), pronotum laterally and pleura clothed with short setae ( Fig. 5A, G ); dorsum and abdomen clothed with long suberect setae, usually longer than width of antennal segment II ( Fig. 5 A–B, I–J); appendages clothed with setae shorter than width of antennal segment II.

STRUCTURE AND MEASUREMENTS. Body ca 3.6–3.8× longer than pronotum width; frons protruding anteriad at distance subequal to at least half of eye diameter in dorsal view ( Figs 1 , 5B ), ca 2.0× as wide as long, vertex ca 1.1–1.4× as wide as eye diameter; head ca 1.2–1.4× as wide as high ( Fig. 5C ); antennal segment I ca 1.2–1.4× longer than vertex width, segment II ca 2.9–3.2× longer than vertex width, and ca 2.2–2.3× longer than segment I; segment III subequal to segment I, segment IV slightly shorter than segment III; labial segments I and II subequal in length, segments III and IV each shorter than segment II, subequal in length to each other ( Fig. 5D ); pronotum ca 1.4–1.5× wider than long, ca 0.9× wider than head, with single oval depression medially; metepisternum with very shallow ridge ( Fig. 5G ); hind femur ca 1.5× longer than head height; tarsal segment I almost twice as long as segment II, segment II slightly shorter than segment III ( Fig. 5E ).

GENITALIA. Not dissected.

Distribution

Known from a single locality in northeastern South Australia ( Fig. 11 ).

Differential diagnosis

Due to its surface and oval body shape (see diagnosis) Carvalhoma taplini is not very similar to the congenerics.
