Lathropus parvulus Grouvelle 1878: 73

Diagnosis. Length, 1.16mm – 1.34mm. The adults of this species strongly resemble those of L. robustulus in their rather broad, rounded pronotum ( Fig. 19-20 ), and the armature of the internal sac ( Fig. 21 ), but differ in being bicolored ( Fig. 1-2 ) (versus all dark in L. robustulus ) and with the sculpture of the pronotum arranged in an obliquely parallel linear pattern ( Fig. 27 ). They differ from those of the other bicolored species treated here in their body form and genitalic characters.

Distribution. Mexico, Central America, Bahamas, Cayman Islands, Dominican Republic; Turks and Caicos.

Specimens examined. Many from Central America , plus 99 from: BAHAMAS: Great Inagua: strand S of Middle Point ; CAYMAN ISLANDS: Cayman Brac: jct. Hemmington Rd. at Songbird Dr .; Maj. Donald Dr.,. 6km E. jct. Ashton Reid Dr .; south side road west; Sovereign Heights ; The Creek ; Grand Cayman: no specific locality; Little Cayman: North Coast Rd. ,. 1km W Olivine Kirk Dr. ; 3km SE Spot Bay ; DOMINICAN REPUBLIC: Barahona: Payaso ; Monseñor Novel: Bonao ; Pedernales: Cabo Rojo ; km. 24.5 N. Cabo Rojo ; Peravia: 12km SE Rio Ocoa ; La Vega: 1km S Manabao ; TURKS AND CAICOS: Grand Turk: Turks and Caicos Nat. Mus. ( FSCA, RHTC)

Discussion. The West Indian representatives of this widespread species differ somewhat from the Central American population in being generally paler, but the two populations are very similar in body shape, sculpture, and genitalic characters.
