Ordo: Orthoptera
Familia: Tetrigidae
Genus: Choriphyllum
Name
Choriphyllum bahamense Perez-Gelabert & Otte, 1999 – Wikispecies link – Pensoft Profile
- Choriphyllum bahamensis Perez-Gelabert & Otte, 1999: 454 (original description and type drawings); Silva et al. 2019[1]: 3, 6, 9–12, 35 (information on types; identification key, type photographs) (Note! Choriphyllum is of neuter gender, so the correct specific epitheton should be “bahamense” which agrees in gender with the genus). Taxonomic and nomenclatural history.
Type locality
The Bahamas: B. W. I. Exuma: Hummingbird Cay W of Georgetown (Perez-Gelabert and Otte 1999[2]).
Type specimens
Holotype. The Bahamas • 1 ♂; Exuma: Hummingbird Cay W of Georgetown; 12 Jun 1968; B. K. Dozier leg.; FSCA. Paratype. The Bahamas • 1 ♀; Exuma: Hummingbird Cay W of Georgetown; 12 Jun 1968; B. K. Dozier leg.; FSCA.
Distribution
(Fig. 2). Known only from the type locality, small Hummingbird Cay Island (Perez-Gelabert and Otte 1999[2]; Silva et al. 2019[1]). Due to the very small area of occupancy and extent of occurrence, as well as the affinity towards the rainforest habitat, the species might be endangered, but this has to be assessed through fieldwork. There are no new records since the description.
Diagnosis
(Figs 1, 3). Choriphyllum bahamense can be differentiated from its congeners by: (1) the caudal tip of the pronotum which reaches the tips of the hind knees, but not beyond (reaches behind the hind knees in C. (sagrai)), (2) the shape of the caudal tip of the pronotum which is excised vertically (in C. (sagrai) and C. saussurei excised at an angle) and (3) the moderate concave slope of the caudal margin of the crest (in C. (sagrai) the crest is higher, convex and sharply sloped and, in C. saussurei, it is lower and concave, but more sharply sloped, with a strong undulation).

The red line shows the position of the highest point of the pronotal crest. The blue arrow points to the anterior margin of the pronotum; the green arrow points to the posterior pronotal tip; and the purple arrow points to the caudal margin of the pronotal crest. Shown are silhouettes of the type specimens of each species. For C. sagrai, shown is the silhouette of Serville’s (1838)[3] drawing of the holotype. The capital sinus is marked in red and pointed out in grey.](/wiki/File:Dez-70-129-g003.jpg)
