156 Euura latibasis (Lindqvist, 1949)

Figs 152, 387

Pteronidea latibasis Lindqvist, 1949: 77–79 .

Diagnosis

Females are from nearly completely pale to mostly black dorsally, and pale ventrally. Externally and based on the lancet, most similar to E. dorsata and E. fuscarima ( E. bipartita group). Lamnium is 1.8–1.9 times as long as radix in E. latibasis (n = 1), but about 2.0–2.4 times as long in E. dorsata (n = 2) and 2.3–2.8 times as long in E. fuscarima (n = 2), but the difference might not hold for E. latibasis and E. dorsata . The middle and apical sutures of the lancet of E. fuscarima might also be more straight than in E. latibasis . Euura seriepunctata and E. serela sp. nov. have also quite a similar lancet, but the serrulae seem to be less protruding and the lamnium is 2.3–2.4 (n = 1) times as long as the radix in E. seriepunctata (the proportions could be similar in E. serela based on one basally damaged lancet).

Genetics

COI

Based on 3 specimens, maximum within-species distance is 0.15% and the nearest neighbour, diverging by a minimum of 1.67%, is Euura dorsata .

Nuclear

Based on 2 specimens, maximum within-species distance is 0% (0.02% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.33%, is Euura lienterica .
