Name
Salganea Stål, 1877 – Wikispecies link – Pensoft Profile
- Salganea Stål, 1877: 37. Type species: Panesthia morio Burmeister, 1838; Roth 1979[1]: 4; Asahina 1988[2]: 257.
- Mylacrina Kirby, 1903: 414. Type species: Mylacrina wrayi Kirby, 1903. Synonymized by Roth 1977[3]: 60.
Generic diagnosis
(modified after Roth (1979)[1]). Vertex rarely foveolate (except Salganea papua and Salganea mandelsi) and exposed. Pronotum transversal ovate, anterior margin almost straight or slightly convex, lateral margins arched, hind margin almost straight; anterior half depressed, with a pair of curved, oblique grooves; posterior half elevated and punctate. Tegmina and wings fully developed, sometimes mutilated, or reduced, or tegmina reduced but wings absent, or both tegmina and wings absent. If tegmina and wings fully developed, tegmina usually narrow and leathery with base thickened, the humeral area well developed and punctate, anterior margin slightly curved medially, subcostal vein short and unbranched. Hind wings with anal area developed with border smooth and rounded; subcostal vein (Sc) straight and simple or with a small branch at apical part, extending beyond the midline of wing length; radial vein (R) with less than five branches, with or without apical posterior branch (Ap. Post. Br.); median vein (M) simple, rarely with a terminal twigging; cubitus (Cu) with more than 8 branches, at least half of which are incomplete and fuse apically or going to the first plical vein (1Pl). Lateral margin of the 6th abdominal tergum (T6) straight; lateral margin of the 7th abdominal tergum (T7) uneven, caudal angles produced caudally or laterocaudally; anterolateral corners of 6th and 7th abdominal terga usually with holes, sometimes holes also existing in the corners of T3, T4 or T5, which are usually accompanied with small setae or hairs. Abdominal sternites punctured, the last sternite with a marginal ridge extending along the lateral margins. Supra-anal plate transverse; paraprocts broad, left one in ventral view armed with a finger-like projection, which is curved dorsally and whose apex is sclerotized. Subgenital plate flabellate, anterior margin straight or concave, lateral margins oblique, hind margin round. Four genital phallomeres as below: first sclerite of left phallomere (L1) plate-like, well developed but usually not sclerotized, sometimes reduced or absent; second ventromedial sclerite of left phallomere (L2vm) rod-like; second dorsal sclerite of the left phallomere (L2d) elongate, variable; second sclerite of right phallomere (R2) hook-shaped, reduced or absent in some species.
Remarks
Because the irregularities on lateral margin of T7 maybe subobsolete, this genus is similar to Panesthia. With a notch existing anterior to the laterocaudal angle of T7 sometimes, this genus resembles Ancaudellia Shaw, 1925. But it can be distinguished by the following characteristics: 1) anterolateral corners of 6th and 7th abdominal terga usually with holes and holes associated with well spaced setae (Panesthia rarely with holes and without setae, Ancaudellia with grooves and associated with dense patches of contiguous setae); 2) lateral margin of S7 with a ridge extending from anterior margin to hind margin (with a feeble and short ridge, or without a ridge in Panesthia and Ancaudellia).
Although Salganea amboinica, Salganea morio and Salganea passaloides passaloides (Walker, 1868) were recorded from China, none of them were found after our wide survey of collecting and examining loans from other museums. Moreover, Roth (1979)[1] had questioned whether they were truly recorded from China. These species have been excluded in our count for the total number of species in this genus from China, and have been removed from our key to the Salganea from China.
