Watt 1997: 124, fig. 59. Maddison 2010: 426. Synonymized with Lyctus depressiusculus White by Arrow 1909: 194. Penthelispa sophorae: Reitter 1880: 175 . Penthelispa acutangulum Reitter, 1878: 124 . Sharp 1886: 388. Synonymy with Pycnomerus sophorae Sharp in Reitter 1880a:

508. Pycnomerus acutangulus: Hetschko 1930: 61 . Maddison 2010: 426.

Type locality: Lyctus depressiusculus White : Port Nicholson (Wellington). Pycnomerus sophorae Sharp : Tairua. Penthelispa acutangulum Reitter : New Zealand.

Broun number: Lyctus depressiusculus White : none given. Pycnomerus sophorae Sharp : 368. Penthelispa acutangulum Reitter : none given.

Remarks: White did not mention the number of specimens examined of Lyctus depressiusculus , though we located two specimens in the BMNH card-mounted together (the left specimen is the lectotype). Sharp did not mention the number of specimens examined of Pycnomerus sophorae from Tairua sent from Broun, and there are six specimens in the BMNH labeled by Sharp as types mixed in with specimens of P. depressiusculus .

We were unable to locate types of Reitter’s (1878: 124) Penthelispa acutangulum and these are presumed lost. Based on the title of Reitter’s (1878: 113) paper, type (s) should be deposited in Berlin, though types were not located in the Hungarian Natural History Museum (Otto Merkl, pers. comm) or the Museum für Naturkunde, Berlin (Bernd Jaeger and Manfred Uhlig, pers. comm.).

In order to stabilize these names, a lectotype and paralectotype are here designated from the material of Lyctus depressiusculus and a lectotype and five paralectotypes are here designated from the material of Pycnomerus sophorae .

Type material examined: Lyctus depressiusculus White : Lectotype ( BMNH): mounted on same card as paralectotype, left specimen is the lectotype, “Type [round label with red border] // Port Nicholson N Zealand [green label, handwritten] // 67. 18- [round label, handwritten] // Lyctus depressiusculus White Zool. Ereb & Terror [in White’s hand]”. Paralectotype ( BMNH): mounted on same card as lectotype, right specimen is a paralectotype, labels same as lectotype. Pycnomerus sophorae Sharp : Lectotype ( BMNH): card-mounted, “ Pycnomerus sophorae Type N. Zeal d. D.S. [written at base of card in Sharp’s hand] // Type [round label with red border] // Sharp Coll. 1905-313.” Paralectotypes ( BMNH) : 2, mounted together on same card and pin, “ Pycnomerus sophorae Ind. typ. N. Zeal d DS. [written at base of card in Sharp’s hand] // Sharp Coll. 1905-313. // depressus = sophorae [handwritten in pencil] R. D. Pope det. 195_” . Paralectotypes ( BMNH): 3, individually mounted on separate cards and pins, with the following labels on each: “ Pycnomerus sophorae Ind. typ. N. Zeal d DS. [written at base of card in Sharp’s hand] // Sharp Coll. 1905-313.” Penthelispa acutangulum Reitter : Type material not examined .
