Note.

Noted above is the name " Gynandropus obscuricornis (Chd)". It is a junior secondary homonym of Selenophorus obscuricornis Waterhouse, and was re-named Selenophorus neobscuricornis by Noonan (1985a: 40).

Type locality.

“Tablasco” in the Greater Antillean island of Hispaniola.

Diagnosis.

This species is readily separated from the other three West Indian members of the hylacis species group on a combination of: intermediate size, pronotum with obtuse posteriolateral angles and pronotum with posteriolateral impressions punctate.

Descriptive notes.

Data for SBL in Table 1. Habitus as in Fig. 26. Clypeus and labrum with anterior margin of each shallowly concave. Antennae with antennomeres 1 or 1and 2 testaceous, antennomeres 2-11 or 3-11 darker. Mouthparts and legs testaceous. Dorsal surface dark brunneous to brunneo-piceous, lateral bead of pronotum paler. Ventral surface rufo-brunneous to dark brunneous. Elytra with very faint iridescence. Head and pronotum shiny, microlines not visible at 100 ×. Elytra with mesh pattern slightly transverse, sculpticells about 3 –4× wide as long. Pronotum with posteriolateral impressions punctate; posteriolateral angles obtuse. Elytral striae impunctate, except the standard setigerous punctures in striae 2, 5 and 7. Both males and females with adhesive vestiture on tarsomeres 1-4 of fore- and mid-tarsi. Tarsomere 1 of fore-tarsus of females expanded, about 1.5 × the width of tarsomere 2, adhesive vestiture dense, not biseriate. Tarsomere 1 of mid-tarsus of females less expanded, about same width as tarsomere 2, adhesive vestiture dense, not biseriate. Both males and females with four terminal setae near the posterior margin on sternum VII.

Male genitalia. Fig. 28 D–F. Apical portion of phallic median lobe short, broad, symmetrically rounded in dorsal/ventral aspect; endophallus without spines or darkened microtrichial fields; without lamina; ostium anopic. Ventral surface of shaft with two rows of basally directed saw-toothed ridges.

Ovipositor and female reproductive tract. Very similar to S. dessalinesi , Fig. 29A. For details, see this topic for S. dessalinesi , above.

Geographical distribution.

Fig. 30. The known range of this species extends eastward from Greater Antillean Cuba to Puerto Rico, and then in the Lesser Antilles southward from St. Barthélemy and Saba to Martinique.

Chorological affinities and relationships.

The range of this species overlaps the ranges of the other three West Indian members of the hylacis species group. Relationships of S. subquadratus are not postulated beyond species group membership.

Material examined.

In addition to type material, we have seen a total of 65 specimens (41 males, 24 females). See Appendix for details.
