Ectinogramma ochreovittata Huang & Li & Lu & Liu 2025, comb. nov.

Ectinogramma ochreovittata (Breuning, 1947) comb. nov. Fig. 3 A – D 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).
