Diploptera parva Princis, 1953

(Figs. 7–8, 63–65)

Diploptera minor: Bruijning, 1948: 153, locality Java.

Diploptera parva Princis, 1953: 208, localities Java (holotype) & Sumatra (paratype).

Taxonomic notes. D. parva is closely similar to D. minor but smaller and a little darker than the latter. The punctations on tegmina are almost invisible but the dense yellow pubescence is more impressive than other species. The cercus of D. parva is bicolor with basal one segment darker than the other two, whilst that of D. minor is almost unicolor. Bruijning’s (1948) D. minor is from Java instead of Philippines and meets the diagnostic characters of D. parva, which has a smaller size (male overall length 8.5mm, cp. D. minor 11mm) and is densely pubescent on tegmina but hardly punctate; this record should be removed from D. minor and put in D. parva . However, giving the assumption that D. parva was not proposed so far, we could speculate that similar specimens might be determined as D. minor and a “ D. parva ” is not easy to come up. Particular attention should be paid when determining specimens with a small body and brownish coloration.
