Tenagogonus kampaspe : HUNGERFORD & MATSUDA (1958) : 386 -388, pl.1 fig. 5, pl. 7 fig. 4. Tenagogonus ( Tenagogonus ) kampaspe : LANSBURY (1993) : 22 . Material examined. PAPUA NEW GUINEA : MOROBE : ‘New Guinea, Kodoka on rd. / Popondetta 1000’ 5 / km past Oivy Ridge / 30.iv.1989 R . Prior’, 2 JJ (apterous), 2 JJ 1 ♀ (macropterous). EAST SEPIK : ‘ PNG East Sepik / R . Salamin 29.xi. / 1995 R . Prior’, 3 ♀♀ (apterous) ( OXUM ). Remarks. The apterous males are somewhat longer ( 4.6 mm ) than the length ( 4.2 mm ) indicated by HUNGERFORD & MATSUDA (1958) . Moreover, in all the males we have examined the spines on ventrite VII are pointed ventrally, whereas in both the text and the figure of HUNGERFORD & MATSUDA (1958) these spines point caudally roughly in the same plane as the longitudinal axis of the body. Unfortunately we did not get a reaction on our request for the loan of some specimens from the type series. However, as the relative length of antennal and leg segments, the ratios of the abdominal tergites, and the colour pattern, notably of the apterous female, agree very well with the redescription by HUNGERFORD & MATSUDA (1958) , we can hardly consider our material as an undescribed species but as T. kampaspe . This species is only known from the south-eastern peninsular part of New Guinea and from West New Britain.
