Spinogramma ochreovittata Breuning, 1947: 62 (type locality: “ Sumatra, Indonesia ”); Breuning 1961: 202 (catalogue).

Remarks.

Breuning (1959) mentioned the differences between the two species of Spinogramma (i. e., S. ruficollis and S. ochreovittata ) in his description of S. ruficollis ; however, there are several key characters that we would like to add that were not mentioned by Breuning. As stated above, S. ruficollis is synonymous with E. isosceloides ; therefore, this species is compared with E. ochreovittata , and the found differences are detailed below.

The redescription of Ectinogramma reveals many common characteristics between the two species, E. ochreovittata and E. isosceloides . Ectinogramma ochreovittata can be distinguished from the later species by the following characteristics: (1) scape, pedicel and antennomere III dark reddish; basal half and apex of antennomere IV dark reddish, rest of surface reddish brown; antennomeres V – VIII reddish brown except apex reddish brown; antennomere IX reddish brown ( E. isosceloides with entire antennae black); (2) pedicel with a trochiformis and apically outward pointed projection, this projection shorter than the pedicel ( E. isosceloides the pedicel with a spinous and apically outward pointed process in males, this process is longer than the pedicel; pedicle lacking a spinous and apically outward pointed process in females); (3) prothorax black (reddish brown in E. isosceloides ); (4) pronotum with mid-dorsal yellowish-brown pubescence vitta on disc and sides with yellowish-brown pubescence vittae on the anterior 2 / 3 and sparsely scattered short white pubescence behind (pronotum of E. isosceloides sparsely covered with short yellowish-brown pubescence); (5) pronotal disc with transverse wrinkles (disc of E. isosceloides without transverse wrinkles); (6) scutellum densely clothed with short yellowish-brown pubescence (scutellum of E. isosceloides densely clothed with short yellowish pubescence); (7) elytra with a yellowish-brown pubescence band along suture, and side with reddish-brown area on anterior 2 / 5 which gradually constricts apically, the reddish-brown area covered with sparse yellowish-brown pubescence (elytra of E. isosceloides with a pale yellowish pubescence band along suture, and side with reddish-brown area anteriorly, the reddish-brown area covered with short yellowish-brown pubescence); (8) mesanepisternum, mesepimeron and metanepisternum sparsely clothed with short white pubescence ( E. isosceloides with mesanepisternum, mesepimeron and metanepisternum densely clothed with short yellowish pubescence); and (9) tibiae and femora of middle legs and tibiae of hind legs reddish brown ( E. isosceloides with tibiae and femora of middle legs and tibiae of hind legs black).
