Haplaxius cabrerensis Ferreira, McKamey


Haplaxius cabrerensis Ferreira, McKamey  , & Sanchez, n. sp.

Figs. 1–3View FIGURES 1 – 7

Diagnosis. Aedeagus with a narrow dorsal process directed anteriorly and a broad falcate ventral process directed ventroanteriorly.

Description. Length of male with forewings in repose 4.2 mm. Color stramineous to light brown throughout, including forewing veins and stigma. Pygofer in lateral view ( Figs. 1, 2View FIGURES 1 – 7) with posterior margin sinuous, in ventral view ( Fig. 3View FIGURES 1 – 7) with median lobe subtriangular, distally rounded. Abdominal segment X (the “anal flap” of Kramer 1979) simple, symmetrical, without ventral processes, in lateral view ( Figs. 1, 2View FIGURES 1 – 7) ventroposteriorly acute with ventral length 3 × maximum height. Aedeagus asymmetrical with two processes: a narrow acuminate process dorsally, directed anteriorly along aedeagal shaft ( Figs. 1, 2View FIGURES 1 – 7), a broadly based falcate process slightly left of center ( Fig. 3View FIGURES 1 – 7), directed ventroanteriorly. Subgenital plates ( Figs. 1–3View FIGURES 1 – 7) capitate, distally rounded.

Material examined. Holotype ♂ ( USNMAbout USNM): DOMINICAN REPUBLIC, Prov. Maria Trinidad Sanchez, Cabrera, Payita, Baoba del Pinar, N 19 ° 30.709, W 69 ° 55.638. 8 -V- 2008. coll. Mileida Ferreira, Teresa Martinez y Andrea Feliz.

Etymology. The specific epithet is based on the type locality, Cabrera.

Notes. The collection was taken in a coconut plantation, sweeping grass ( Poaceae  ) and weedy herbs. In Kramer’s (1979) key to Neotropical species, H. cabrerensis  keys out to couplet 27, which includes H. tekton (Kramer)  from Peru (aedeagus with three long processes) and H. frontalis (Fowler)  from Mexico (aedeagus lacking long dorsal process). Haplaxius cabrerensis  is easily distinguished from other insular species of the Caribbean by the broad falcate ventral process of the aedeagus, and its abdominal segment X is simple, lacking ventral processes. In contrast, H. crudus  has a narrow digitate ventral process on the aedeagus and an abdominal segment X with a pair of small triangular processes at its base; H. hochae O’Brien (2006)  , from Dominica, has an abdominal segment X with a large convex projection at the base and a sinuous ventral margin. Three Haplaxius  females were collected with the holotype, but their species identity cannot be determined because the collection lot also included a male of H. jamaicae (Kramer)  , the only other Antillean species.
